Description
Technical field
The present invention relates to communication field, relate in particular to the methods, devices and systems of a kind of BRAN and digit subscriber wire interconnection.
Background technology
The broadband access method that broadband wireless access BWA (Broadband wireless access, broadband wireless access) equipment can be provided convenience for the user.Broadband wireless access equipment based on proprietary protocol is arranged at present, the broadband wireless access equipment based on standard agreement is also arranged.The broadband wireless access equipment of IEEE (IEEE) 802.16 standard definitions is subclass of the series standard of wireless access wide band technology.Comprise WIMAX (global interactive inserting of microwave) equipment in the BWA equipment.
The framework of DSL (Digital Subscriber Line) network just enables the type framework by PPP over ATM (ATM bearing point end-to-end protocol (EEP)) to the IP QoS (quality of service) based on Ethernet Aggregation and connectivity (Ethernet-Aggregation be connected) and develops.This universal architecture schematic diagram that enables the type framework as shown in Figure 1.In Fig. 1, provide this respectively and enabled PPPoE (PPP over Ethernet), IPoE (Ethernet bearing IP agreement) and three kinds of pattern protocol stacks of IP based (based on IP) of type framework.
In Fig. 1, T is the reference point between TE (terminal equipment) and DSLModem (DSL modulator-demodulator) in CPN (local network of users) network; U is the reference point between DSL Modem and access point DSLAM (Digital Subscriber Line Access Multiplexer); V is Ethernet Aggregation (Ethernet-Aggregation) reference point between middle DSLAM of Access Network (Access Network) and BRAS (BAS Broadband Access Server); A10 is the reference point between Access Network and SP (service provider), and this reference point can connect ASP (application service provider) to the NSP that has Access Network (Internet Service Provider), or connects NSP to visit ground Access Network under the roaming sight.Adopt the interconnection of DSL access technology between CPN network and Access Network.
Pppoe mode can only adopt the Ethernet bridge connection technology between BRAS and TE.This pattern as link protocol, provides terminal configuration and the control and management capability that is connected with PPP over Ethernet.This pattern is applicable to the clear data business.
The IPoE pattern can only adopt the Ethernet bridge connection technology between BRAS and TE.This pattern allows QoSProvisioning (QoS granting), relies on DHCP (DHCP) fully and provides sign and allocative abilities for TE, and this pattern mainly is applicable to Triple play (data+voice+video is provided) business.
IP based pattern must adopt three layers of route technology of IP between BRAS and TE.This pattern allows IPQoS to be issued to BRAS and DSL Modem, relies on DHCP fully for TE provides sign and configuration, finishes suitable route setting in DHCP discovery (DHCP discovery) stage.This pattern mainly is applicable to Triple play (data+voice+video is provided) business.
IEEE 802.16 is first broadband wireless access standards, and this standard mainly contains two versions: " 802.16-2004 ", promptly the broadband fixed wireless of 802.16 standards inserts version." 802.16e ", promptly the broadband mobile wireless of 802.16 standards inserts version.Wherein, 802.16-2004 has only defined two kinds of network element: BS (base station) and SS (subscriber station), adopts the interconnection of broadband fixed wireless access technology between BS and SS; 802.16e also only defined two kinds of network elements, BS and MS (mobile subscriber station) adopt broadband mobile wireless access technology interconnection between BS and MS.

In the prior art, the interconnect scheme between a kind of WiMAX and the DSL is: the reference point V interconnection in Access Network with WiMAX and DSL.Concrete connected mode as shown in Figure 3, Figure 4.
The shortcoming of this connectivity scenario is:
1, WiMAX and DSL coupling is loose, and the resource of former DSL network (for example DSL cable, DSLAM) fails to maximize the use;
2, when WiMAX base station or ASN quantity for a long time, BRAS will become bottleneck, WiMAX and DSL can be restricted to a certain extent the Scalability (scalability) of network in reference point V interconnection.
In the prior art, the interconnect scheme between another kind of WiMAX and the DSL is: WiMAX and DSL are interconnected in core net.Concrete connected mode as shown in Figure 5.
The shortcoming of this connectivity scenario is:
1, WiMAX and DSL coupling is the loosest, and the resource of former DSL network (for example DSL cable, DSLAM and BRAS) fails to maximize the use;
2, need newly-increased network element IWU (interconnecting unit).
