用户资源请求的处理方法、装置及系统Method, device and system for processing user resource request

技术领域technical field

本发明涉及通信技术领域,特别涉及一种用户资源请求的处理方法、装置及系统。The present invention relates to the field of communication technology, in particular to a method, device and system for processing user resource requests.

背景技术Background technique

3GPP(The 3rd Generation Partnership Project,第三代合作伙伴计划)在TS(Technical Specification,技术规范)23.401定义的SAE(System ArchitectureEvolution,系统架构演进)架构里,UE(User Equipment,用户设备)有两种方式通过SGSN(Serving GPRS Support Node,通用分组无线业务服务支持节点)接入P-GW(Packet DataNetwork-Gateway,分组数据网网关)时:通过S4接口接入SGW(Serving Gateway,服务网关),然后通过S5接口接入P-GW;或者,通过Gn/Gp接口直接接入到P-GW。P-GW通过Gx接口与PCRF(Policy and Charging Rules Function,策略与计费规则功能)进行交互,实现策略计费控制等。In the SAE (System Architecture Evolution, System Architecture Evolution) architecture defined by 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) in TS (Technical Specification, Technical Specification) 23.401, there are two types of UE (User Equipment, user equipment) When accessing P-GW (Packet DataNetwork-Gateway, packet data network gateway) through SGSN (Serving GPRS Support Node, general packet radio service service support node): access SGW (Serving Gateway, serving gateway) through S4 interface, and then Access to the P-GW through the S5 interface; or, directly access to the P-GW through the Gn/Gp interface. The P-GW interacts with PCRF (Policy and Charging Rules Function) through the Gx interface to implement policy and charging control.

UE在发起资源请求时,通过激活、修改或去激活PDP(Packet Data Protocol,分组数据协议)上下文实现与P-GW以及PCRF的交互。当UE发起PDP上下文激活或者修改过程时,可以在该PDP上下文中关联TFT(Traffic Flow Template,传输流模板),通过修改关联的TFT中的PF(Packet Filter,报文过滤器),实现具体的修改操作。当PDP上下文中不携带TFT时,可以通过Create New TFT(创建新的TFT)操作在该上下文新建关联的TFT;对于已经关联TFT的PDP上下文,可以通过Delete Existing TFT(删除现有TFT)操作删除已经关联的TFT,没有关联TFT的PDP上下文叫做通配上下文。When the UE initiates a resource request, it realizes interaction with the P-GW and the PCRF by activating, modifying or deactivating a PDP (Packet Data Protocol, packet data protocol) context. When the UE initiates the PDP context activation or modification process, it can associate a TFT (Traffic Flow Template, transport flow template) in the PDP context, and realize specific Modify operation. When the PDP context does not carry a TFT, you can create a new associated TFT in the context through the Create New TFT (create a new TFT) operation; for a PDP context that has been associated with a TFT, you can delete it through the Delete Existing TFT (delete an existing TFT) operation The associated TFT and the PDP context without associated TFT are called wildcard contexts.

现有技术中,当UE发起二次PDP上下文激活请求时,会出现所述二次PDP上下文不携带TFT的情况。In the prior art, when the UE initiates a secondary PDP context activation request, the secondary PDP context does not carry a TFT.

现有技术中至少存在如下问题:At least the following problems exist in the prior art:

由于UE创建二次PDP上下文时不携带TFT,P-GW作为PCEF(Policy and ChargingEnforcement Function,策略与计费执行功能)无法与PCRF正常交互报文过滤器的操作,从而无法获取对应的PCC(Policy and Charging Control,计费和策略控制)规则,导致无法完成二次PDP上下文激活时承载上TFT的操作。Since the UE does not carry the TFT when creating the secondary PDP context, the P-GW, as a PCEF (Policy and Charging Enforcement Function, Policy and Charging Enforcement Function), cannot normally interact with the PCRF for the operation of the message filter, and thus cannot obtain the corresponding PCC (Policy Enforcement Function). and Charging Control, charging and policy control) rules, resulting in the inability to complete the operation of carrying the TFT when the PDP context is activated for the second time.

与现有技术相比,本发明实施例能够在UE发起二次PDP上下文激活请求且不携带TFT时,SGSN根据二次PDP上下文激活请求构造通配报文过滤器或P-GW根据资源创建请求构造通配报文过滤器,P-GW向PCRF发送通配报文过滤器,使P-GW能与PCRF正常交互而获得PCC规则,从而实现在PDP上下文激活时对承载上TFT的操作。Compared with the prior art, the embodiment of the present invention can construct a wildcard packet filter according to the secondary PDP context activation request by the SGSN or P-GW according to the resource creation request when the UE initiates a secondary PDP context activation request and does not carry a TFT. A wildcard packet filter is constructed, and the P-GW sends the wildcard packet filter to the PCRF, so that the P-GW can normally interact with the PCRF to obtain PCC rules, thereby realizing the operation of the TFT on the bearer when the PDP context is activated.

进一步的,UE在激活所述二次PDP上下文后,当发起PDP上下文修改,创建新TFT时,如图2所示,在步骤103之后,本实施例提供的方法进一步包括:Further, after the UE activates the secondary PDP context, when initiating PDP context modification and creating a new TFT, as shown in FIG. 2, after step 103, the method provided by this embodiment further includes:

PCRF同步设置第一PCC规则的状态时,如果CCR包含的第一PCC规则的状态是去激活,PCRF删除第一PCC规则,如果是临时去激活,则不删除,只是改变状态。When the PCRF synchronously sets the state of the first PCC rule, if the state of the first PCC rule contained in the CCR is deactivated, the PCRF deletes the first PCC rule, and if it is temporarily deactivated, it does not delete it, but only changes the state.

109、所述P-GW接收第三CCA,去激活或临时去激活所述第一PCC规则。109. The P-GW receives the third CCA, and deactivates or temporarily deactivates the first PCC rule.

在激活二次上下文的基础上,通过以上步骤,P-GW可以进一步地获取到UE请求的报文过滤对应的PCC规则,并将已经安装的通配报文过滤器对应的PCC规则的状态置为去激活或临时去激活,使得UE请求的TFT与承载中TFT的状态保持一致,并实现PCRF和P-GW之间报文过滤器的处理。On the basis of activating the secondary context, through the above steps, the P-GW can further obtain the PCC rule corresponding to the packet filtering requested by the UE, and set the status of the PCC rule corresponding to the installed wildcard packet filter to For deactivation or temporary deactivation, the TFT requested by the UE is consistent with the state of the TFT in the bearer, and the processing of the message filter between the PCRF and the P-GW is realized.

进一步的,在所述UE创建新的TFT后,所述UE发起PDP上下文修改,删除所述新TFT,当所述第一PCC规则的状态为去激活时,如图3所示,在步骤109之后,本实施例提供的方法进一步包括:Further, after the UE creates a new TFT, the UE initiates a PDP context modification and deletes the new TFT. When the state of the first PCC rule is deactivated, as shown in FIG. 3 , in step 109 Afterwards, the method provided in this embodiment further includes:

110、所述P-GW接收所述SGSN发送的第二资源修改请求,所述第二资源修改请求包含的TFT操作码为删除TFT。110. The P-GW receives the second resource modification request sent by the SGSN, where the TFT operation code included in the second resource modification request is delete TFT.

111、所述P-GW发送第四CCR,所述第四CCR包含所述通配报文过滤器,所述通配报文过滤器对应的PF操作码为增加。111. The P-GW sends a fourth CCR, where the fourth CCR includes the wildcard packet filter, and the PF operation code corresponding to the wildcard packet filter is increase.

112、所述P-GW接收第四CCA,所述第四CCA中包含所述通配报文过滤器对应的第三PCC规则。112. The P-GW receives a fourth CCA, where the fourth CCA includes a third PCC rule corresponding to the wildcard packet filter.

115、所述P-GW接收第五CCA,删除所述第二PCC规则。115. The P-GW receives the fifth CCA, and deletes the second PCC rule.

需要说明的是,所述第三PCC规则虽然与所述第一PCC规则同为通配报文过滤器对应的PCC规则,但是二者可能为同一个PCC规则,也可能为不同的PCC规则。It should be noted that although the third PCC rule and the first PCC rule are both PCC rules corresponding to the wildcard packet filter, they may be the same PCC rule or different PCC rules.

通过以上步骤,用户请求删除二次PDP上下文中的TFT时,在通配报文过滤器对应的PCC规则被删除的情况下,P-GW通过在CCR中包含通配报文过滤器的方式,PCRF可以删除现有TFT对应的PCC规则并增加通配PCC规则,使得在实现UE请求删除TFT的同时,保证PCRF和P-GW之间报文过滤器的处理。Through the above steps, when the user requests to delete the TFT in the secondary PDP context, if the PCC rule corresponding to the wildcard packet filter is deleted, the P-GW includes the wildcard packet filter in the CCR, The PCRF can delete the PCC rule corresponding to the existing TFT and add a wildcard PCC rule, so that the processing of the message filter between the PCRF and the P-GW can be ensured while implementing the UE request to delete the TFT.

进一步的,在所述UE创建新的TFT后,所述UE发起PDP上下文修改,删除所述新TFT,当所述第一PCC规则的状态为临时去激活时,如图4所示,在步骤109之后,本实施例提供的方法进一步包括:Further, after the UE creates a new TFT, the UE initiates a PDP context modification to delete the new TFT.
