Abstract
This invention opens a quality of service negotiation method in width-band code division multi access system, with this method ICP originates quality of service (QoS) strategy request, also can originate Qos policy request by system data service platform, the step of first scheme is: users equipment (UE) sends the data packet of service request to internet content provider (ICP), according to the above statement service request ICP forms QoS policy request and sends to the system policy server (PS); PS makes the decision according to QoS policy request information of ICP, then PS sends policy response including the result of decision, furthermore ICP sends UE the service response formed according to the above statement policy response for UE. The second scheme has similar steps with the first scheme; the above statement scheme can make the LIE that doesn't support SIP taking QoS negotiation from end to end, it makes this invention having better generality.
Description
Technical field
The present invention relates to service quality (QoS) machinery of consultation in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system.
Background technology
In the WCDMA system, data service is varied, and for example 3G (Third Generation) Moblie cooperative association (3GPP) is summarized as four classes with data service: conversation class, stream class, interactive class and background classes.Each business all has different requirements at aspects such as time delay, shake, the error rate, retransmission mechanism, and promptly every kind of business all has different qos requirements.From laterally, the end points (or node) that data service end to end is relevant in the WCDMA system is subscriber equipment (UE), wireless access network (RAN), GPRS (general grouped wireless communication protocol) professional Zhi Jiedian (SGSN), GGSN (GGSN) and internet content service provider (ICP); From vertically, relate to network carrying layer, RAB (RAB) layer, global system for mobile communications (UMTS) bearing bed, IP layer and operation layer.
In QoS negotiations process end to end, interdependent node RAN, the SGSN of WCDMA system and GGSN will come distributing system resource according to the demand of applied business, and QoS guarantees thereby provide end to end.But from the protocol hierarchy of WCDMA system, the applied business layer is opaque to RAN, SGSN and GGSN, like this, how to obtain the characterisitic parameter of application layer, realizes that the distribution of WCDMA system resource has just become a problem.Present method is the characterisitic parameter that session initiation protocol (SIP) consults to obtain application layer that passes through that defines in the 5th version (R5) of 3GPP agreement, and the parameter maps of Huo Deing is to the WCDMA system then.Existing method be at UE before the ICP requested service, obtain the characterisitic parameter of application layer by the SIP session.Detailed process is:
1, UE sends to policy control functions server (PCF) with SIP conversation description parameter, comprises the IP address of application layer type of service, UE, the information such as bandwidth of wishing system's reservation in the parameter;
2, PCF holds consultation by SIP signaling and called UE, obtains the conversation description parameter (SDP) of called agreement, comprises the IP address of purpose UE in the parameter, the information such as bandwidth that can reserve;
3, PCF determines corresponding IP qos parameter according to SIP conversation description parameter, generate QoS decision-making token then and be handed down to UE, UE is when carrying out block data protocol context (PDP Context) activation, carry the QoS token of negotiation and give GGSN, GGSN carries this token and makes a strategic decision to PCF request QoS by general open policy service protocol agreement (COPS), PCF provides the QoS decision-making according to token, issue GGSN then, so far just finished the application layer traffic performance to the mapping between the WCDMA device characteristics.
Because existing method has been used Session Initiation Protocol and has been used as end-to-end QoS negotiation signaling in the WCDMA system, QoS negotiations process is end to end finished between UE and PCF, this requires UE must support Session Initiation Protocol, does not support the UE of Session Initiation Protocol can't adopt the method to carry out QoS negotiation end to end.Therefore, existing QoS consults to have limitation, and versatility is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of versatility quality of service negoriation method in the WCDMA system preferably, use this method can make the UE that does not support Session Initiation Protocol realize that QoS consults end to end.
For achieving the above object, the quality of service negoriation method in a kind of broadband CDMA system provided by the invention comprises:

Step 2:PS makes a strategic decision according to qos policy solicited message and the operator's configured strategy of ICP;
Step 3:PS sends the policy response that comprises the result of decision to ICP, sends to UE by ICP according to the service response that above-mentioned policy response forms giving UE again.
Described step 1 further comprises:
Step 11: subscriber equipment (UE) sends to ICP (ICP) with the service request data bag, comprises the IP address of UE, the port numbers of UE, the IP address of ICP, port numbers and the traffic type information of ICP in the described packet;
Step 12:ICP forms the qos policy request according to above-mentioned information and issues PS, comprises the idle bandwidth resource information of port numbers, type of service and ICP itself of IP address, the ICP of port numbers, the ICP of IP address, the UE of UE in the described request.
Described step 3 further comprises:
Step 31:PS sends the qos policy response that comprises the result of decision to ICP, comprises the IP address of UE, the port numbers of UE, the IP address of ICP, the port numbers of ICP, definite system resource reservation situation in the described response;
Step 32:ICP utilizes above-mentioned policy response to form the service response that sends to UE and sends to UE, comprises in the described service response whether the IP address of UE, the port numbers of UE, the IP address of ICP, port numbers and the business of ICP are allowed to information.
Between step 2 and step 3, also comprise:
The GPRS of system strategy server and system (general grouped wireless communication protocol) gateway support node (GGSN) the consulting tactical result of decision.
Quality of service negoriation method in the another kind of broadband CDMA system provided by the invention comprises:
Steps A 1: subscriber equipment (UE) is issued data service platform with the service request data bag, forms service quality (QoS) strategy request by data service platform according to above-mentioned service request and issues system strategy server (PS);
Steps A 2:PS consults the ICP traffic handing capacity according to above-mentioned strategy request and ICP (ICP);
Steps A 3:PS makes a strategic decision according to traffic handing capacity and the operator's configured strategy of ICP;
Steps A 4:PS sends the policy response that comprises the result of decision to data service platform, and data service platform sends to UE according to the service response that above-mentioned policy response forms giving UE.
Described steps A 1 further comprises:
Steps A 11: subscriber equipment (UE) sends to data service platform with the service request data bag, comprises the IP address of UE, the port numbers of UE, the IP address of ICP, port numbers and the traffic type information of ICP in the described packet;
