( WiMAX ) 系统接入网, 以及应用该接入网实现接入核心网的方法。 发明背景 (WiMAX) System access network, and a method of applying the access network to access the core network. Background of the invention
2001年 12月, 电气和电子工程师协会(IEEE )颁布了用于在城域 网中提供最后一公里无线宽带接入的 IEEE 802.16标准, 其工作频带位 于 10G到 66GHz之间。 但目前所说的 802.16标准主要包括 802.16a、 802.16RevD和 802.16e三个标准。 其中, 802.16a是为工作在 2 ~ 11GHz 频段的非视距(NLOS )宽带固定接入系统而设计的, 在 2003年 1月被 IEEE批准通过; 802.16RevD是 802.16a的增强型,主要目的是支持室内 用户驻地设备 ( CPE ); 802.16e是 IEEE802.16a/d的进一步延伸, 其目的 是在已有标准中增加数据移动性。  In December 2001, the Institute of Electrical and Electronics Engineers (IEEE) promulgated the IEEE 802.16 standard for providing last-mile wireless broadband access in metropolitan area networks with operating bands between 10G and 66GHz. However, the current 802.16 standard mainly includes three standards of 802.16a, 802.16RevD and 802.16e. Among them, 802.16a is designed for non-line-of-sight (NLOS) broadband fixed access systems operating in the 2 ~ 11GHz band, and was approved by the IEEE in January 2003; 802.16RevD is an enhanced version of 802.16a, the main purpose is Support for Indoor Customer Premises Equipment (CPE); 802.16e is a further extension of IEEE 802.16a/d, which aims to increase data mobility in existing standards.
为了提升 802.16系列标准在全球的推广和应用, 由众多设备和组件 供应商组成了名为全球微波接入互操作性论坛的非盈利性组织, 旨在通 过确保宽带无线接入设备的兼容性和互操作性, 加快基于 IEEE 802.16 系列标准的宽带无线网絡的部署。 通常情况下, 将应用 802.16系列标准 中规定的技术实现无线宽带接入的系统称为 WiMAX系统。  In order to promote the global promotion and application of the 802.16 series of standards, a number of equipment and component suppliers form a non-profit organization called the Global Interoperability Forum on Microwave Access, which aims to ensure the compatibility of broadband wireless access devices. Interoperability to accelerate the deployment of broadband wireless networks based on the IEEE 802.16 family of standards. In general, a system that implements wireless broadband access using the technology specified in the 802.16 series of standards is called a WiMAX system.
802.16系列标准规定了 WiMAX系统的空中接口部分协议层, 主要 包括物理层(PHY )和媒体接入控制层(MAC )两个部分。 其中, PHY 层在物理上完成对信号的调制解调以及编解码等操作; MAC层主要完 成 WiMAX系统的媒体接入控制功能。 使用上述物理层和 MAC层的 WiMAX系统, 具有覆盖范围广、 可 扩展性强以及业务质量(QoS )控制等优点。 具体如下: The 802.16 series of standards specifies the protocol layer of the air interface part of the WiMAX system, which mainly includes the physical layer (PHY) and the medium access control layer (MAC). The PHY layer physically performs modulation, demodulation, and codec operations on the signal; the MAC layer mainly implements the media access control function of the WiMAX system. The WiMAX system using the above physical layer and MAC layer has the advantages of wide coverage, strong scalability, and quality of service (QoS) control. details as follows:
1. 宽带无线接入、 覆盖范围广。  1. Broadband wireless access and wide coverage.
802.16标准是为在包括视距、 近视距和非视距等各种传播环境中获 得最优性能而设计的。 WiMAX 系统采用的正交频分复用 (OFDM )调 制的最大通信距离可达 4km, 支持高达 70Mbit/s的频谱效率。 该系统采 用诸如网状网的先进网络拓朴和诸如波束成形、 STC以及天线分集等天 线技术来进一步改善覆盖。这些先进技术也可用来提高频谱效率、容量、 复用以及每射频信道的平均与峰值吞吐量。  The 802.16 standard is designed to achieve optimal performance in a variety of propagation environments including line of sight, near line of sight, and non-line of sight. WiMAX systems use Orthogonal Frequency Division Multiplexing (OFDM) modulation for maximum communication distances of up to 4km, supporting spectral efficiencies of up to 70Mbit/s. The system uses advanced network topologies such as mesh networks and antenna technologies such as beamforming, STC and antenna diversity to further improve coverage. These advanced technologies can also be used to increase spectral efficiency, capacity, multiplexing, and average and peak throughput per RF channel.
2. 可扩展性强  2. Strong scalability
在物理层, 802.16支持灵活的射频信道带宽和信道复用, 当网络扩 展时, 可以作为增加小区容量的一种手段。 此标准还支持自动发送功率 控制和信道盾量测试, 因此可作为物理层的附加工具来支持小区规划和 部署以及频谱的有效使用。 当用户数增加时, 运营商可通过扇形化和小 区分裂来重新分配频语。 另外, WiMAX 系统对多信道带宽的支持, 使 设备制造商能够适应各国政府对频普使用和分配而制定独特管制办法。  At the physical layer, 802.16 supports flexible RF channel bandwidth and channel multiplexing, which can be used as a means of increasing cell capacity when the network is expanding. This standard also supports automatic transmit power control and channel shield testing, so it can be used as an additional tool in the physical layer to support cell planning and deployment and efficient use of spectrum. As the number of users increases, operators can redistribute the frequency through sectorization and cell splitting. In addition, WiMAX systems support multi-channel bandwidth, enabling device manufacturers to adapt to the unique regulatory regimes that governments use for frequency usage and distribution.
3. QoS控制  3. QoS control
802.16的 WiMAX系统提供多种服务类型和服务水平,其中的 MAC 层完全面对连接, 充分的保证了业务的可靠性; 另外, WiMAX 系统通 过优化的调度算法保证了不同业务对不同带宽和时延的需求。  The 802.16 WiMAX system provides multiple service types and service levels, in which the MAC layer is completely connected to the network, which fully guarantees the reliability of the service. In addition, the WiMAX system guarantees different bandwidth and delay for different services through optimized scheduling algorithms. Demand.
虽然上述的 WiMAX 系统具有如此优越的性能, 但是由于 IEEE802.16系列协议只规定了 WiNMAX系统无线网络架构中的空中接 口部分, 而并未规定 WiMAX接入网(WiRAN )接入诸如全球移动通信 系统(GSM )、 码分多址(CDMA ) 系统以及宽带码分多址(WCDMA ) 系统等核心网的网络架构及接入方法,因此 WiMAX系统的用户站(SS ) 和移动台 (MSS )无法通过 WiRAN接入到核心网中, 从而无法使用核 心网中丰富的网络资源和业务功能。 发明内容 Although the above WiMAX system has such superior performance, the IEEE 802.16 series protocol only specifies the air interface part of the WiNMAX system wireless network architecture, and does not stipulate WiMAX access network (WiRAN) access such as the global mobile communication system. The network architecture and access method of the core network such as (GSM), Code Division Multiple Access (CDMA) system and Wideband Code Division Multiple Access (WCDMA) system, so the subscriber station (SS) of the WiMAX system And the mobile station (MSS) cannot access the core network through WiRAN, so the rich network resources and service functions in the core network cannot be used.

The MAC&PHY module is connected to the terminal SS/MSS through the air interface. After receiving the SS/MSS service request, the MAC&PHY module establishes the dedicated signaling for transmitting signaling of the SS/MSS air interface according to the radio resource allocated by the RRM module. Connecting, and forwarding the service request to the GW module; the RRM module is configured to allocate the radio resource according to the service request; the GW module receives and establishes a dedicated signaling connection between the GW module and the core network and the MAC&PHY module according to the received service request And establishing a user plane instance for performing service transmission with the core network according to the service establishment request sent by the core network, and sending an instruction to notify the MAC&PHY module to establish a service data connection of the air interface. Based on the foregoing access network architecture and working principle, a method for accessing a WiMAX system to a core network is provided. FIG. 1 is a schematic structural diagram of a WiMAX system access network (WiRAN) according to the present invention, including: a MAC&PHY module, a GW module, and an RRM module. Among them, the AC&PHY module is responsible for connecting the terminal SSMSS, completing the processing of the air interface part, such as encoding/decoding, modulation/demodulation, mapping/demapping, connection establishment and maintenance, etc., and keeping the terminal synchronized with WiRAN.
RRM模块负责 WiRAN中与该 RRM模块对应的基站(BS ) 内部的 无线资源管理, 完成 BS 内部小区 /扇区的无线资源管理, 具体包括 BS 空口无线资源的管理和调度、 BS辖域内用户 QoS的管理、 以及对无线 链路信道环境的自适应等过程, 还负责 SS/MSS在相邻 BS间进行切换 时的无线资源管理和调度,负责 WiRAN内部多个 BS之间、多个 WiRAN 之间的无线资源管理和调度以及 QoS管理等。  The RRM module is responsible for radio resource management in the base station (BS) corresponding to the RRM module in the WiRAN, and completes radio resource management of the cell/sector of the BS, specifically including management and scheduling of BS air interface radio resources, and user QoS in the BS domain. Management, and adaptation to the radio link channel environment, etc., is also responsible for radio resource management and scheduling when the SS/MSS switches between adjacent BSs, and is responsible for inter-VARAN between multiple BSs and multiple WiRANs. Radio resource management and scheduling, and QoS management.
GW模块包括信令面和用户面网关功能, 负责 WiMAX系统中控制 面的信令传输, 主要完成 WiRAN与核心网设备信令面协议栈的适配和 信令协议的传送等操作; 并负责 WiMAX系统中用户面的数据传输, 完 成 WiRAN与核心网设备用户面协议栈的适配和用户数据的传送。因此, 也可以将 GW模块进行信令面和用户面分离,将 GW模块分为信令网关 ( SGW )模块和数据网关 ( DGW )模块, 分别负责将信令面和用户面 适配到核心网。  The GW module includes a signaling plane and a user plane gateway function, and is responsible for signaling transmission of the control plane in the WiMAX system, mainly performing operations such as adaptation of the signaling plane protocol stack of the WiRAN and the core network device, and transmission of the signaling protocol; and is responsible for WiMAX.

The WiRAN receives the SS/MSS service request through the MAC&PHY module, and performs information exchange between the GW module and the core network to establish a connection between the WiRAN and the SS/MSS and the core network to implement interworking between the terminal SS/MSS and the core network.
另外, 由于终端 SS/MSS在与核心网之间进行业务传输期间, 可能 会发生位置的改变, 因此在上述的网络架构中,还包括切换控制器(HO Controller ) 寻呼控制器(Paging Controller ) 以及多播广播业务服务器 ( MBS Server )等模块, 以便实现 WiMAX系统中终端 SS/MSS的迁移 和切换等功能。 其中, HO Controller设置在基站中, 用于进行 BS间切 换过程的协调和决策控制,在完成 BS间的切换时,进行 BS和核心网之 间信令接口的迁移, 并负责 BS和核心网之间用户数据面接口的迁移; Paging Controller用于进行寻呼控制消息的下发和寻呼过程的调度处理; MBS Server用于进行多播广播业务( MBS )的调度、过程处理以及 MBS 业务的下发。 MBS server—方面是内容提供者的入口, 另一方面需要规 划下属的 BS的多播广播数据的发送, 并且分发多播广播数据给下属的 BS。 In addition, since the location change may occur during the service transmission between the terminal SS/MSS and the core network, the above-mentioned network architecture further includes a paging controller (HO Controller) paging controller (Paging Controller). And multicast broadcast service server Modules such as (MBS Server) to implement migration and switching of terminal SS/MSS in WiMAX systems. The HO Controller is set in the base station, and is used for performing coordination and decision control of the inter-BS handover process. When the handover between the BSs is completed, the signaling interface between the BS and the core network is migrated, and the BS and the core network are responsible. Paging Controller is used to perform paging control message delivery and paging process scheduling; MBS Server is used for multicast broadcast service (MBS) scheduling, process processing, and MBS services. hair. The MBS server-side is the entry of the content provider, on the other hand, it is necessary to plan the transmission of the multicast broadcast data of the subordinate BS, and distribute the multicast broadcast data to the subordinate BS.
MBS Server和 Paging Controller根据需要可以分布式地存在于接入 网附近, £辑上, 一个 MBS Server和 Paging Controller可以和多个 BS 直接相连, Paging Controller通过 I-BP接口与 BS互联, MBS Server通 过 I-BM接口与 BS 互联。 目前大部分无线通信系统的核心网都支持 Paging Controller,部分支持 MBS Server。 因此 Paging Controller和 MBS Server可以根据实际网络配置和需要放置。  The MBS Server and the Paging Controller can be distributed in the vicinity of the access network as needed. In the series, one MBS Server and Paging Controller can be directly connected to multiple BSs. The Paging Controller is interconnected with the BS through the I-BP interface, and the MBS Server passes. The I-BM interface is interconnected with the BS. At present, the core network of most wireless communication systems supports Paging Controller, and some support MBS Server. Therefore, the Paging Controller and MBS Server can be placed according to the actual network configuration and needs.

本实施例中的 BS中包含 MAC&PHY模块、 BRRM模块、 DGW模 块以及 HO Controller模块,并且其中的 DGW模块通过 I-BSO模块接入 核心网; BSSN中包含 SGW模块、 CRRM模块、 Relocation Controller 模块、 MBS Server模块以及 Paging Controller模块, 并且其中的 SGW 模块通过 I-BNO接口与核心网连接。本实施例中各个模块的功能与实施 例 1中各个模块的功能完全相同。 The BS in this embodiment includes a MAC&PHY module, a BRRM module, a DGW module, and a HO Controller module, and the DGW module accesses the core network through the I-BSO module; the BSSN includes an SGW module, a CRRM module, a Relocation Controller module, and an MBS.

另外由图 7可见, 本实施例中的 BSSN与 BS是多对多的关系, 即 一个 BSSN下接多个 BS, 而每个 BS除了能够接入其自身所在 WiRAN 中的 BSSN上之外, 还能构接入其它 WiRAN中的 BSSN, 通常情况下 默认该 BS接入其所在 WiRAN中的 BSSN上。 这种做法的好处在于, 当默认 BSSN工作异常时, BS能够自动选择新的 BSSN, 以保证正常的 网絡传输。此种网络架构可以减少一个 BSSN导致大面积接入网的瘫痪, 保证了 WiMAX接入网络的运行鲁棒性, 为整个网络提供较好的容错机 制。  It can be seen from FIG. 7 that the BSSN and the BS in this embodiment are in a many-to-many relationship, that is, one BSSN is connected to multiple BSs, and each BS can access the BSSN in its own WiRAN. It can be configured to access the BSSN in other WiRANs. Generally, the BS accesses the BSSN in its WiRAN by default. The advantage of this approach is that when the default BSSN works abnormally, the BS can automatically select a new BSSN to ensure normal network transmission. This kind of network architecture can reduce the flaw of a large-area access network caused by a BSSN, ensure the robust operation of the WiMAX access network, and provide a better fault-tolerant mechanism for the entire network.

步骤 306.核心网收到业务请求后, 对终端 SS MSS进行鉴权认证, 如果鉴权认证成功, 则继续执行步骤 307; 否则, 结束本处 WiRAN接 入核心网的流程。  Step 306. After receiving the service request, the core network authenticates the terminal SS MSS. If the authentication succeeds, proceed to step 307; otherwise, terminate the process of the WiRAN accessing the core network.
如果核心网不需要验证接入终端的身份, 则省略本步骤的鉴权认证 过程。  If the core network does not need to verify the identity of the access terminal, the authentication process of this step is omitted.
步骤 307.核心网通过 I-BNO接口向 BSSN下发业务建立请求, 同 时 BS中的 BRRM模块对其所在的 BS进行资源控制, 而后 SGW模块 根据该业务建立请求, 通过 I-BB接口建立用于与核心网进行业务数据 传输的 DGW用户面实例。  Step 307.

至此, 本实施例中终端 SS/MSS通过 WiRAN与核心网的业务接入 过程完成。  So far, in this embodiment, the terminal SS/MSS is completed through the service access process of the WiRAN and the core network.
上述步骤 301至 308与实施例 2中的步骤 201至 208完全相同。 此后,终端 SS/MSS通过 BS中的 DGW模块与核心网进行交互, 实 现业务数据的传输,并在发生迁移或者切换时,由 BS中的 HO Controller 模块、 BSSN中的 Relocation Controller模块、 MBS Server模块以及 Paging Controller模块相配合, 保证业务的正常传输。 The above steps 301 to 308 are identical to the steps 201 to 208 in the second embodiment. Thereafter, the terminal SS/MSS interacts with the core network through the DGW module in the BS to implement transmission of service data, and when the migration or handover occurs, the HO Controller in the BS The module, the Relocation Controller module in the BSSN, the MBS Server module, and the Paging Controller module work together to ensure normal transmission of services.
另外, 本实施例的网络架构也可以采用图 8所示的方案, 即将图 7 中的 MBS Server模块和 Paging Controller模块从 BSSN中分离出来, 并 分别通过 I-BM和 I-BP接口为多个 BSSN所共享。 在使用此种网络架构 接入核心网时, 其具体过程与上述步骤 301至 308完全相同。  In addition, the network architecture of this embodiment may also adopt the scheme shown in FIG. 8, that is, the MBS Server module and the Paging Controller module in FIG. 7 are separated from the BSSN, and are respectively configured by the I-BM and the I-BP interface. Shared by BSSN. When using this network architecture to access the core network, the specific process is exactly the same as steps 301 to 308 above.
另外, 本实施例的网络架构除了包括接入所必须的 MAC&PHY模 块、 BRRM模块、 SGW模块、 CRRM模块和 DGW模块之外, 还可以 包含 HO Controller模块、 Relocation Controller模块、 MBS Server模块 以及 Paging Controller模块中的一个或者任意几个的组合。  In addition, the network architecture of this embodiment may include a HO Controller module, a Relocation Controller module, an MBS Server module, and a Paging Controller module in addition to the MAC & PHY module, the BRRM module, the SGW module, the CRRM module, and the DGW module necessary for access. One or any combination of the two.
由于目前存在多种类型的核心网, 因此上述三个实施例中的 BS和 BSSN可根据具体接入的核心网类型,采用不同的接口,例如,当 WiRAN 接入 WCDMA核心网时, BS和 BSSN均通过 IU-PS,接口与 WCDMA网 络进行通信。  Since there are many types of core networks, the BS and the BSSN in the above three embodiments may adopt different interfaces according to the core network type of the specific access, for example, when the WiRAN accesses the WCDMA core network, the BS and the BSSN. Both communicate with the WCDMA network through the IU-PS interface.
另外, 上述三个实施例中信令的处理和数据的处理分别由 SGW模 块和 DGW模块完成, 由于 SGW模块代表 WiRAN的控制面, DGW模 块代表 WiRAN的用户面, SGW和 DGW可以放置在不同的物理实体中, 实现了用户面与控制面的分离, 便于 WiRAN的管理和整体协调、 提高 设备效率和稳定性。  In addition, the processing of signaling and the processing of data in the above three embodiments are respectively performed by the SGW module and the DGW module. Since the SGW module represents the control plane of the WiRAN, the DGW module represents the user plane of the WiRAN, and the SGW and the DGW can be placed in different manners. In the physical entity, the separation of the user plane and the control plane is realized, which facilitates the management and overall coordination of the WiRAN, and improves the efficiency and stability of the device.
实施例 4:  Example 4:
本实施例中, 无需预先在 WiRAN 中设置 BSSN, 而是将本发明 MAC&PHY模块、 GW模块和 RRM模块均设置在 BS中, 而 WiRAN 则具有多个这样的 BS。  In this embodiment, it is not necessary to set the BSSN in the WiRAN in advance, but the MAC&PHY module, the GW module, and the RRM module of the present invention are all set in the BS, and the WiRAN has a plurality of such BSs.
图 9为本发明第四实施例 WiRAN接入到核心网的网络架构示意图, 其中 GW模块分为 SGW模块和 DGW模块,并且 MAC&PHY模块、 SGW 模块、 DGW模块和 RRM模块均位于 BS中。 其中, BS分布式地接入 到核心网, 在纵向上, BS和核心网之间通过 I-BO接口互联, 每个 BS 通过 I-BO接口适配核心网协议栈, 包括传输网络层协议、 无线网絡层 的协议以及高层应用协议, 每个 BS在用户面和控制面都只与一个核心 网相连。 在横向上, BS之间通过 I-BS接口互联, 每个 BS通过 I-BS接 口和其他 BS进行信令和数据交互,完成不同 BS之间的切换、迁移和数 据转发等功能。 用户端 SS MSS通过 U接口接入 BS。 FIG. 9 is a schematic diagram of a network architecture of a WiRAN accessing a core network according to a fourth embodiment of the present invention, where a GW module is divided into an SGW module and a DGW module, and a MAC&PHY module, SGW The module, the DGW module, and the RRM module are all located in the BS. The BS is distributedly connected to the core network. In the vertical direction, the BS and the core network are interconnected through an I-BO interface, and each BS adapts the core network protocol stack through the I-BO interface, including a transport network layer protocol. The protocol of the wireless network layer and the high-level application protocol, each BS is connected to only one core network on the user plane and the control plane. In the horizontal direction, the BSs are interconnected through an I-BS interface, and each BS performs signaling and data interaction with other BSs through the I-BS interface to complete functions such as handover, migration, and data forwarding between different BSs. The client SS MSS accesses the BS through the U interface.
当终端 SS/MSS使用上述接入网接入核心网时, 终端 SS MSS首先 通过空中接口向 BS 发出携带有终端标识及业务代码等信息的业务请 求。 BS 中的 MAC&PHY模块接收到终端 SS/MSS的业务请求后, BS 中的 RRM 模块根据业务请求进行该 BS 内部的无线资源分配。 MAC&PHY模块在 RRM模块分配的无线资源上建立该 SS/MSS空中接 口的专用信令连接,并将业务请求通过公共信道传送给 BS中的 SGW模 块。 SGW模块根据所收到业务请求中携带的终端标识为该 SS/MSS分配 用于记录其接入网絡的信息的实例,并建立 SGW模块与 MAC&PHY模 块的专用信令连接。 SGW模块进一步建立与核心网之间的专用信令连 接, 并把 SS/MSS的业务请求组装成核心网能够识别的 I-BO接口消息, 通过 I-BO接口发送给核心网, 以向核心网请求业务。  When the terminal SS/MSS accesses the core network by using the foregoing access network, the terminal SS MSS first sends a service request carrying the terminal identifier and the service code to the BS through the air interface. After the MAC&PHY module in the BS receives the service request of the terminal SS/MSS, the RRM module in the BS performs radio resource allocation within the BS according to the service request. The MAC&PHY module establishes a dedicated signaling connection for the SS/MSS air interface on the radio resources allocated by the RRM module, and transmits the service request to the SGW module in the BS through the common channel. The SGW module allocates an instance of the SS/MSS for recording information of its access network according to the terminal identifier carried in the received service request, and establishes a dedicated signaling connection between the SGW module and the MAC&PHY module. The SGW module further establishes a dedicated signaling connection with the core network, and assembles the SS/MSS service request into an I-BO interface message that can be identified by the core network, and sends the message to the core network through the I-BO interface to the core network. Request business.
核心网接收到来自 BS的 I-BO接口消息后, 通过 I-BO接口向 BS 下发业务建立请求, 同时 BS中的 RRM模块对其所在的 BS进行资源控 制, 而后 SGW模块根据该业务建立请求和资源控制结果, 通过内部原 语通知 DGW模块建立用于与核心网进行业务数据传输的用户面实例。 然后, SGW模块通过内部原语通知 MAC&PHY模块建立空口的业务数 据连接, 并在该空口业务数据连接建立成功后, 通过 SGW模块向核心 网返回业务连接建立成功消息; 核心网收到该消息后通过 SGW模块和 MAC&PHY模块向 SS/MSS返回业务接入成功消息,指明本次业务连接 已经成功建立。 至此, 本实施例中终端 SS/MSS通过 WiRAN与核心网 的业务接入过程完成。 After receiving the I-BO interface message from the BS, the core network sends a service establishment request to the BS through the I-BO interface, and the RRM module in the BS performs resource control on the BS where the BS is located, and then the SGW module establishes a request according to the service. And the resource control result, the DGW module is notified by the internal primitive to establish a user plane instance for performing service data transmission with the core network. Then, the SGW module notifies the MAC&PHY module to establish an air interface service data connection by using an internal primitive, and after the air interface service data connection is successfully established, returns a service connection establishment success message to the core network through the SGW module; the core network passes the message and then passes the message. SGW module and The MAC&PHY module returns a service access success message to the SS/MSS, indicating that the service connection has been successfully established. So far, in this embodiment, the terminal SS/MSS is completed through the service access process of the WiRAN and the core network.
此后,终端 SS/MSS通过 BS中的 DGW模块接收来自于核心网的业 务数据, 并在发生迁移或者切换时, 由 BS中的 HO Controller通过 I-BS 接口控制终端 SS/MSS在 BS间的切换。 具体切换过程为:  Thereafter, the terminal SS/MSS receives the service data from the core network through the DGW module in the BS, and controls the switching of the terminal SS/MSS between the BSs through the I-BS interface by the HO Controller in the BS when the migration or handover occurs. . The specific switching process is:
HO Controller通过 MAC&PHY模块收到 SS/MSS上报的相邻小区信 号质量的测量艮告后, 根据小区信号质量确定候选目标 BS。 然后, HO Controller利用 SGW模块通过 I-BS接口对各目标 BS进行咨询其资源满 足情况以及终端切换过来所需求的 QoS能否得到保证等信息。在获得这 些信息之后, HO Controller选定一个最终的目标 BS,并通过 MAC&PHY 模块下发切换执行信息给终端 SS/MSS。 终端 SS/MSS执行切换到目标 BS的操作, 并向 BS的 HO Controller返回终端切换到目标 BS的消息。 BS的 HO Controller收到该消息后,指示 MAC&PHY模块释放针对此终 端的空口资源, 向 GW模块发送消息以指示 GW模块进行 BS和核心网 之间信令面接口和用户数据面接口的迁移。  After receiving the measurement report of the quality of the neighboring cell signal reported by the SS/MSS, the HO Controller determines the candidate target BS according to the cell signal quality. Then, the HO Controller uses the SGW module to consult each target BS through the I-BS interface, and whether the resource sufficiency and the required QoS can be guaranteed. After obtaining this information, the HO Controller selects a final target BS and delivers handover execution information to the terminal SS/MSS through the MAC&PHY module. The terminal SS/MSS performs an operation of switching to the target BS, and returns a message that the terminal switches to the target BS to the HO Controller of the BS. After receiving the message, the HO Controller of the BS instructs the MAC&PHY module to release the air interface resource for the terminal, and sends a message to the GW module to instruct the GW module to perform the migration of the signaling plane interface and the user data plane interface between the BS and the core network.
Paging Controller通过 I-BP接口完成寻呼消息的下发。 具体地, 在 核心网需要寻呼某个终端时, 核心网通过 I-BO接口下发寻呼请求消息, 由 SGW模块将寻呼请求消息转发给 Paging Controller Paging Controller 收到寻呼请求消息后, 根据寻呼请求消息中所带的寻呼区域信息, 确定 进行寻呼的 BS范围。 然后 Paging Controller通过 SGW模块通知各 BS 进行寻呼。在确定终端被寻呼到以后, Paging Controller停止对终端的寻 呼或者在超时以后再重新进行寻呼, 在一定次数寻呼都失败以后, 就表 示整个寻呼失败。  The Paging Controller delivers the paging message through the I-BP interface. Specifically, when the core network needs to page a terminal, the core network sends a paging request message through the I-BO interface, and the SGW module forwards the paging request message to the Paging Controller Paging Controller after receiving the paging request message. The BS range in which the paging is performed is determined based on the paging area information carried in the paging request message. The Paging Controller then notifies each BS to page through the SGW module. After determining that the terminal is paged, the Paging Controller stops the paging of the terminal or re-patches after the timeout. After a certain number of paging failures, the entire paging fails.
MBS Server通过 I-BM接口完成多播广播业务( MBS ) 的下发和传 输调度。 首先, SS/MSS通过 MAC&PHY模块向 MBS server发送消息 以查询 MBS业务内容列表。 MBS server 4 至 lj该消息、后, 向 SS MSS返 回包含 MBS内容列表、 组播 IP地址 /端口号等信息的响应。 SS/MSS选 定接收的 MBS业务的组播 IP地址 /端口号后, 将该信息发送给 BS。 BS 收到该信息后与 MBS server进行 MBS业务内容接收的鉴权过程。 在鉴 权完成后, BS发送包括 MBS下行业务参数等信息的消息给 SS/MSS。 The MBS Server completes the delivery and transmission of the multicast broadcast service (MBS) through the I-BM interface. Transfer scheduling. First, the SS/MSS sends a message to the MBS server through the MAC&PHY module to query the MBS service content list. After the MBS server 4 to lj the message, the SS MSS returns a response including information such as the MBS content list, the multicast IP address/port number, and the like. After the SS/MSS selects the multicast IP address/port number of the received MBS service, the SS/MSS sends the information to the BS. After receiving the information, the BS performs an authentication process of receiving the MBS service content with the MBS server. After the authentication is completed, the BS sends a message including information such as the MBS downlink service parameter to the SS/MSS.
SS/MSS收到该消息后发送消息给 BS, 以获取用于解密 MBS业务数据 包的 MBS 密钥。 BS 向 SS/MSS 返回包含 MBS 密钥的响应消息给 SS/MSS。 SS/MSS在获取 MBS下行业务参数和 MBS密钥后, 利用得到 的信息接收从 MBS server通过 BS下发的相关 MBS业务数据包, 进入 正常的 MBS业务接收状态。 After receiving the message, the SS/MSS sends a message to the BS to obtain the MBS key used to decrypt the MBS service data packet. The BS returns a response message containing the MBS key to the SS/MSS to the SS/MSS. After obtaining the MBS downlink service parameters and the MBS key, the SS/MSS uses the obtained information to receive the relevant MBS service data packet sent from the MBS server through the BS, and enters the normal MBS service reception state.
如果 SGW模块和 DGW模块的功能包含在 GW模块中, 即该 GW 模块作为包含信令面和用户面网关功能的独立实体,则上述所有与 SGW 模块之间的信息交互均为与 GW模块间的信息交互。  If the functions of the SGW module and the DGW module are included in the GW module, that is, the GW module functions as a separate entity including the signaling plane and the user plane gateway function, the information interaction between all the foregoing and the SGW module is between the GW module and the GW module. Information exchange.
本实施例提供的网络架构中的核心网可以为各种不同的通信系统核 心网, 比如 NGN核心网、 3G核心网、 2G核心网等。 接入不同通信系 统核心网的原理与上述过程是类似的, 区别仅在于: 为接入不同通信系 统核心网, 需要利用不同的接口和传送不同核心网能够识别的消息。 下 面仅以 WiRAN接入 3G WCDMA PS核心网为例进行说明。  The core network in the network architecture provided in this embodiment may be a core network of various communication systems, such as an NGN core network, a 3G core network, a 2G core network, and the like. The principle of accessing the core network of different communication systems is similar to the above process. The only difference is that: To access the core network of different communication systems, different interfaces and messages that can be identified by different core networks need to be used. The following is an example of WiRAN access to a 3G WCDMA PS core network.
图 10为本发明第四实施例 WiRAN接入 WCDMA PS核心网的网络 架构。 其中, WiRAN包含与图 9所示的 WiRAN同样的逻辑功能模块, 在此不再详细描述。图 9所示的接口 I-BO在这里为 WCDMA PS核心网 的 IU-PS接口。 这样, BS—方面适配 IU-PS接口的信令面协议栈, 包 括传输网络层协议, 如 SCCP MTP3B/SCTP 等、 无线网络层的协议 RANAP以及非接入层 NAS的协议; 另一方面适配 IU-PS接口的用户面 协议栈, 如 GTP-U等。 并通过在 BS中解析 IUPS接口 NAS层消息, 将 其适配成与终端之间的业务应用层协议, 以实现终端与核心网 NAS 层 的通信, 并隔离终端与核心网的耦合关系。 FIG. 10 is a network architecture of a WiRAN accessing a WCDMA PS core network according to a fourth embodiment of the present invention. The WiRAN includes the same logical function modules as the WiRAN shown in FIG. 9, and will not be described in detail herein. The interface I-BO shown in Figure 9 is here the IU-PS interface of the WCDMA PS core network. In this way, the BS-side adapts the signaling plane protocol stack of the IU-PS interface, including the transport network layer protocol, such as SCCP MTP3B/SCTP, the protocol RANAP of the wireless network layer, and the protocol of the non-access stratum NAS; User plane with IU-PS interface Protocol stack, such as GTP-U. And through the analysis of the IUPS interface NAS layer message in the BS, it is adapted to the service application layer protocol between the terminal and the terminal, so as to realize the communication between the terminal and the core network NAS layer, and isolate the coupling relationship between the terminal and the core network.
当 WiMAX系统中终端 SS/MSS使用上述接入网接入 WCDMA PS 核心网时, 首先 SS/MSS通过 MAC&PHY模块完成 IEEE 802.16/IEEE 802.16e空口协议里定义的接入初始化过程。 在 SS/MSS完成与 BS之间 的接入网的接入初始化过程以后, SS/MSS通过 MAC&PHY模块发起接 入 WCDMAPS核心网的业务请求, MAC&PHY模块收到该业务请求后 建立空中接口的信令连接。 该业务请求被转发到 SGW模块, SGW模块 收到业务请求后建立 IU-PS接口信令连接, 并将业务请求中包含的用户 IMSI/PTMSL请求的业务类型等信息组装数据包,通过标准 IU-PS接口 的初始用户数据传输( Initial UE DT ) 消息发给核心网。  When the terminal SS/MSS in the WiMAX system uses the above access network to access the WCDMA PS core network, the SS/MSS first completes the access initialization procedure defined in the IEEE 802.16/IEEE 802.16e air interface protocol through the MAC&PHY module. After the SS/MSS completes the access initialization process of the access network with the BS, the SS/MSS initiates a service request for accessing the WCDMAPS core network through the MAC&PHY module, and the MAC&PHY module establishes the signaling of the air interface after receiving the service request. connection. The service request is forwarded to the SGW module, and the SGW module establishes an IU-PS interface signaling connection after receiving the service request, and assembles the data packet of the service type requested by the user IMSI/PTMSL included in the service request, and passes the standard IU- The Initial User Data Transfer (Initial UE DT) message of the PS interface is sent to the core network.
核心网收到 Initial UE D 消息后, 通过 BS下发消息给 SS/MSS以 对用户 USIM进行鉴权认证。 SS/MSS鉴权认证完成后, 把鉴权认证结 果上报给 BS , BS将鉴权认证结果组成相应的响应消息后上报给核心网。  After receiving the Initial UE D message, the core network sends a message to the SS/MSS to authenticate the user USIM. After the authentication of the SS/MSS authentication is completed, the authentication and authentication result is reported to the BS, and the BS composes the authentication response result into a corresponding response message and reports it to the core network.
BS中的 SGW模块根据 SS/MSS发送的业务请求, 通过 IU-PS接口 向核心网发起业务请求, 即分组数据协议(PDP )激活请求, 核心网收 到 PDP激活请求后向 BS下发 RAB指配请求消息, BS中的 SGW模块 收到无线接入承载(RAB )指配请求消息后, 建立 DGW与核心网的用 户面实例, 并通知 MAC&PHY模块建立空中接口的新的传输业务数据 的业务数据连接。 MAC&PHY模块完成业务数据连接建立后,通过 SGW 模块向核心网返回 RAB建立成功消息。核心网收到 RAB建立成功消息 后, 向 BS下发 PDP激活请求响应; SGW模块把收到的 PDP激活请求 响应消息组成 SS/MSS 应用层的消息, 通过 MAC&PHY模块发送给 SS/MSS, 以通知 SS/MSS业务请求成功。 至此整个业务建立完成。 由于本发明在一定范围内是分布式架构, 网元之间采用 IP协议, 保 证了网络之间的信息交互是通过 IP路由来实现, 而不用专用的电路连 接, 因此保证了网元之间的连接的易实现性,适用于网络全 IP互联的情 况。 The SGW module in the BS sends a service request to the core network through the IU-PS interface according to the service request sent by the SS/MSS, that is, a packet data protocol (PDP) activation request, and the core network sends the RAB finger to the BS after receiving the PDP activation request. With the request message, the SGW module in the BS receives the radio access bearer (RAB) assignment request message, establishes a user plane instance of the DGW and the core network, and notifies the MAC&PHY module to establish the service data of the new transmission service data of the air interface. connection. After the MAC&PHY module completes the establishment of the service data connection, the RAB establishment success message is returned to the core network through the SGW module. After receiving the RAB establishment success message, the core network sends a PDP activation request response to the BS; the SGW module forms the received PDP activation request response message into the SS/MSS application layer message, and sends the message to the SS/MSS through the MAC&PHY module to notify The SS/MSS service request was successful. So far the entire business has been established. Since the present invention is a distributed architecture within a certain range, the IP protocol is adopted between the network elements to ensure that information interaction between the networks is implemented by IP routing without using dedicated circuit connections, thereby ensuring the relationship between the network elements. The easy implementation of the connection is suitable for the case of network all-IP interconnection.
基于本实施例中 WiRAN的架构, 本发明所提供的用于 WiMAX系 统接入到核心网的方法包括以下步骤:  Based on the architecture of the WiRAN in this embodiment, the method for accessing the WiMAX system to the core network provided by the present invention includes the following steps:

Before initiating the access procedure, the SS/MSS completes the access initialization procedure defined in the IEEE 802.16/IEEE 802.16e air interface protocol through the MAC&PHY module. For the process, refer to the IEEE 802.16/IEEE 802.16e air interface protocol, which is not described here.
另外, 终端 SS/MSS通过该业务倚求中的终端标识指明发起端, 以 便在成功接入核心网后, 接收所需要的业务数据。  In addition, the terminal SS/MSS indicates the initiator through the terminal identifier in the service dependency, so as to receive the required service data after successfully accessing the core network.
步驟 402. BS中的 MAC&PHY模块摔收到终端 SS/MSS的业务请求 后, 请求 R M模块分配无线资源, RRM模块根据该业务请求中的业务 数据量大小、 以及当前网络资源的状况, 确定是否允许该 SS/MSS的接 入, 并在允许接入的情况下, 进行该 BS内部的无线资源分配。  Step 402. After receiving the service request of the terminal SS/MSS, the MAC&PHY module in the BS requests the RM module to allocate the radio resource, and the RRM module determines whether to allow the service according to the size of the service data in the service request and the current network resource status. The SS/MSS accesses, and in the case of allowing access, performs radio resource allocation within the BS.
本步骤中, RRM模块将诸如发射功率、 已接入的用户数量、 BS的 处理能力等当前网络的可用资源与业务请求中的业务数据量大小相对 比, 如果可用网络资源能够为终端提供其所需的业务数据量, 则允许当 前业务请求接入; 否则拒绝当前业务请求接入。  In this step, the RRM module compares the available resources of the current network, such as the transmit power, the number of users that have accessed, and the processing capability of the BS, with the amount of service data in the service request, if the available network resources can provide the terminal with the location. The amount of service data required allows the current service to request access; otherwise, the current service request is denied access.
在允许业务请求接入的情况下 , RRM模块进行其所在 BS内部的网 络资源分配, 例如, 为当前业务指定信道、 分配带宽等。 步骤 403. BS中的 MAC&PHY模块在 RRM模块分配的无线资源上 建立该 SS/MSS空中接口的用于传送信令的专用信令连接, 并将业务请 求传送给 BS中的 SGW模块。 In the case of allowing service request access, the RRM module performs network resource allocation within the BS where it is located, for example, assigning a channel to the current service, allocating bandwidth, and the like. Step 403. The MAC&PHY module in the BS establishes a dedicated signaling connection for transmitting signaling of the SS/MSS air interface on the radio resource allocated by the RRM module, and transmits the service request to the SGW module in the BS.
步驟 404. BS 中的 SGW模块根据该业务请求中的终端标识, 为 SS/MSS分配用于记录 SS/MSS接入网絡的各种信息的实例, 并利用该 实例建立 SGW模块与 MAC&PHY模块的专用信令连接。  Step 404. The SGW module in the BS allocates an instance of the SS/MSS for recording various information of the SS/MSS access network according to the terminal identifier in the service request, and uses the instance to establish a dedicated for the SGW module and the MAC&PHY module. Signaling connection.
本步骤中, SGW模块分配实例是指, 在 BS内存中为本次业务请求 建立信息描述, 该信息描述中至少包括本次业务请求的终端 SSMSS、 请求的业务类型等信息, 这些信息用于管理 SS/MSS接入网络的各种活 动。  In this step, the SGW module allocation instance refers to, in the BS memory, the information description is established for the current service request, and the information description includes at least the terminal SSMSS of the current service request, the requested service type, and the like, and the information is used for management.

由于步骤 403 中建立了 BS与 SS/MSS空中接口的专用信令连接, 因此本步骤中 SGW模块建立与核心网之间的专用信令连接。 至此, 由 终端 SS/MSS至核心网的专用信令连接建立完毕。  Since the dedicated signaling connection between the BS and the SS/MSS air interface is established in step 403, the SGW module establishes a dedicated signaling connection with the core network in this step. So far, the dedicated signaling connection from the terminal SS/MSS to the core network is established.
步骤 406. 核心网收到业务请求后, 对终端 SS/MSS进行鉴权认证, 如果鉴权认证成功, 则继续执行步骤 407; 否则结束本此 WiRAN接入 核心网的流程。  Step 406. After receiving the service request, the core network performs authentication on the terminal SS/MSS. If the authentication is successful, the process proceeds to step 407; otherwise, the process of accessing the core network by the WiRAN is ended.
本步骤中, 对终端 SS/MSS进行鉴权认证具体包括: 核心网首先向 BS下发鉴权认证请求, BS中的 SGW模块通过 BS中的 MAC&PHY模 块, 将该鉴权认证请求转发给 SS/MSS; SS/MSS在鉴权认证完成后, 向 核心网返回鉴权认证响应, 核心网根据该响应的内容完成鉴权。 本步骤 中的鉴权认证可以釆用数字证书、 共享密钥等常规方法。  In this step, the authentication of the terminal SS/MSS includes: The core network first sends an authentication request to the BS, and the SGW module in the BS forwards the authentication request to the SS through the MAC&PHY module in the BS. After the authentication is completed, the SS/MSS returns an authentication authentication response to the core network, and the core network completes the authentication according to the content of the response. The authentication method in this step can use conventional methods such as digital certificates and shared keys.
如果核心网不需要验证接入终端的身份, 则省略本步骤的鉴权认证 过程。 If the core network does not need to verify the identity of the access terminal, the authentication of this step is omitted. Process.
步骤 407.核心网向 BS下发业务建立请求, BS中的 SGW模块收到 请求后, 通知 RRM模块对其所在的 BS进行资源控制, 然后 SGW模块 根据该业务建立请求, 建立用于 DGW模块与核心网进行业务数据传输 的 DGW用户面实例。  Step 407. The core network sends a service establishment request to the BS. After receiving the request, the SGW module in the BS notifies the RRM module to perform resource control on the BS where it is located, and then the SGW module establishes a DGW module according to the service establishment request. The DGW user plane instance of the core network for service data transmission.
本步骤中的 DGW用户面实例用于配合核心网中的用户面实例实现 接入成功后的数据传输, 并且在考虑移动互联网协议(IP ) 的情况下, DGW即为移动 IP网络中的外部代理(FA )模块。。  The DGW user plane instance in this step is used to cooperate with the user plane instance in the core network to implement data transmission after successful access, and in consideration of the mobile internet protocol (IP), the DGW is an external proxy in the mobile IP network. (FA) module. .
步骤 408. BS中的 SGW模块通知 MAC&PHY模块建立空口的业务 数据连接,并在 MAC&PHY模块的空口业务数据连接建立成功后, SGW 模块向核心网返回连接成功的消息。  Step 408. The SGW module in the BS notifies the MAC&PHY module to establish a service data connection of the air interface, and after the air interface service data connection of the MAC&PHY module is successfully established, the SGW module returns a message of successful connection to the core network.
步骤 409.核心网收到连接成功响应消息后, 通过 BS中的 SGW模 块和 BS 中的 MAC&PHY 模块将连接成功的响应消息返回给终端 SS/MSS, 以通知 SS/MSS业务请求成功。 本实施例假设连接建立成功的 情况, 如果连接建立不成功, 则返回连接建立失败消息。  Step 409. After receiving the connection success response message, the core network returns a response message of successful connection to the terminal SS/MSS through the SGW module in the BS and the MAC&PHY module in the BS, to notify the SS/MSS service request that the request is successful. This embodiment assumes that the connection establishment is successful. If the connection establishment is unsuccessful, a connection establishment failure message is returned.
至此, 本实施例中终端 SS/MSS通过 BS与核心网的业务接入过程 冗成。  So far, in this embodiment, the terminal SS/MSS is redundant through the service access process between the BS and the core network.
此后,终端 SS/MSS通过 BS中的 DGW模块接收来自于核心网的业 务数据, 并在发生迁移或者切换时, 由 BS 中的 HO Controller控制 SS MSS在 BS之间的切换。 具体的切换控制过程包括如下步驟:  Thereafter, the terminal SS/MSS receives the service data from the core network through the DGW module in the BS, and controls the switching of the SS MSS between the BSs by the HO Controller in the BS when migration or handover occurs.
