Addressed to the appropriate PCRF. 在本发明所示的图中,虛线箭头表示可选步骤,实线箭头表示必选步骤。 In the present invention shown in FIG dashed arrow indicates an optional step, the solid line arrow indicates a required step. 目前,利用图1所示的框架图进行策略计费控制的过程为:PCRF接收到来自PCEF的策略计费规则请求消息,检测自身是否存储有该消息相关的用户策略计费控制签约信息,如果没有则向SPR获取该消息相关的用户策略计费控制签约信息。 Currently, the frame shown in FIG. 1 to FIG policy and charging control process is performed as: PCRF receives the policy charging rule request message from the PCEF, detects whether the message is stored associated with user subscription policy and charging control information, if You did not get the message associated with the user policy and charging control subscription information to the SPR. 随后,PCRF利用自身存储的或从SPR中获取到的该消息相关的用户策略计费控制签约信息进行基于该消息相关的用户策略计费控制签约信息的策略计费规则决策,并将决策后的策略计费规则发送给PCEF。 Subsequently, the PCRF stores the user use their own billing policies from the SPR to acquire or the control message related subscription information policy charging rule decision based on the message subscription information associated with a user policy and charging control, and the decision policy and charging rules sent to the PCEF. 最后,PCEF根据接收到的策略计费规则对该消息相关的用户进行策略计费。 Finally, PCEF user based on the received information related to the policy and charging rules of conduct policy and charging. 但是,由于同一用户通常允许通过一个或多个接入点(AP, Access Point) 使用网络服务,也就是说,对于同一用户,SPR中可能存在与之对应的一个或多个用户策略计费控制签约信息,而利用图1所示的框架图进行策略和计费控制的过程仅仅公开了PCRF要获取用户策略计费控制签约信息的过程, 没有公开针对具体业务中同一用户有多个用户策略计费控制签约信息时如果有选择的获取相应的用户策略计费控制签约信息的过程,从而使得具体业务部具备可实施性。 However, the same user generally allows one or more access points (AP, Access Point) to use network services, that is to say, for the same user, the SPR corresponding thereto may be present in one or more user policy and charging control subscription information, and using the frame shown in FIG. 1 and FIG process for policy and charging control only discloses a PCRF to obtain the policy and charging control during user subscription information, the policy does not disclose a plurality of users counted for the same user specific business subscription fee when the control information acquisition procedure if the selected corresponding user subscription policy and charging control information, so that the unit includes a specific business can be implemented. 在3GPP release7的23.203协议中,已经明确了在承栽建立过程中,PCEF 与PCRF进行交互过程中,PCRF发现没有存储此次交互涉及用户的用户策略计费控制签约信息时,发送携带有UE标识的用户策略计费控制签约信息请求到SPR, SPR根据该请求携带的UE标识发送对应的用户策略计费控制签约信息到PCRF。 In the 23.203 protocol 3GPP release7, it has been made clear in the process of establishing commitment planted, PCEF interacts with the PCRF process, PCRF found no user interaction involves storing the user policy and charging control subscription information, send carries UE identity user subscription policy and charging control information request to the SPR, SPR sends a corresponding request carries the identifier of the UE according to a user subscription policy and charging control information to the PCRF. PCRF再根据接收到的用户策略计费控制签约信息和用户请求的业务请求进行策略计费决策,并将策略计费决策发送给PCEF进行执行。 PCRF re-subscription request according to the user information and the received user request for policy and charging control traffic policy and charging decisions, and the policy and charging decisions sent for execution to the PCEF. 具体过程如图2所示,其具体步骤为:步骤201、 PCEF接收到从外部节点发送来的业务承栽建立请求消息。 Specific process shown in Figure 2, including the following steps: Step 201, PCEF receives traffic transmitted from an external bearing plant node setup request message. 步骤202、 PCEF根据接收到消息携带的信息,寻址到一个正确的PCRF 后,向其发送策略计费规则请求消息,在该消息携带UE标识。 Step 202, PCEF according to the received information carried in the message, addressed to a proper PCRF, the policy and charging rule request to send the message, the message carries the UE identity. 步骤203、 PCRF根据接收到的该消息携带的UE标识判断是否存储有该UE标识对应的用户策略计费控制签约信息,如果是,则转入步骤205(该步骤未在图中示出);否则,向SPR发送获取用户策略计费控制签约信息请求消息。 Step 203, PCRF according to the UE identifier carried in the message received is stored is determined whether the UE corresponding to the user identification policy and charging control subscription information, if yes, proceeds to step 205 (this step is not shown in the drawing); otherwise, get sent to the SPR policy and charging control user subscription information request message. 步骤204、 SPR根据接收到的该消息携带的信息,发送所存储的用户策略计费控制签约信息到PCRF。 Step 204, SPR based on the information carried in the received message, the user sends the stored policy and charging control subscription information to PCRF. 步骤205、 PCRF根据从PCEF接收到的策略计费规则请求消息携带的业务承载信息以及从SPR接收到的或存储的对应该UE标识的用户策略计费控制签约信息对策略计费进行决策。 Step 205, PCRF receives the request message from the PCEF according to the policy and charging rules for a user identification policy and charging control should UE subscription information and service information received from the SPR bearer or stored on the policy and charging decisions. 步骤206、 PCRF将决策后的策略计费规则发送给PCEF,由PCEF来执行策略计费控制。 Step 206, PCRF after the charging rules to a Policy Decision PCEF, is performed by a policy and charging control PCEF. 步骤207、如果本次业务承载与在线计费相关,则PCEF发送信用请求消息到OCS。 Step 207, if the current bearer traffic associated with the online charging, the PCEF sends a credit request message to the OCS. 步骤208、 OCS发送信用响应消息到PCEF,该消息携带是否为本次业务提供服务的信息,PCEF根据接收到响应消息携带的信息为对本次业务进行策略计费控制。 Step 208, OCS transmits a credit response message to the PCEF, whether the message carries a service-oriented views provide information services, PCEF to perform policy and charging control of the current service according to the received response information carried in the message. 步骤209、 PCEF发送业务承载建立响应给外部节点。 Step 209, PCEF sends a service node bearer setup response to the external. 从图2可以看出,该技术方案只是明确了PCRF如何向SPR获取用户签约数据,但对于SPR如何存储PCRF的地址信息没有详细描述;对于在PCRF如何删除用户策略计费控制签约信息没有详细描述;对于在SPR如果删除了已存储的用户策略计费控制签约信息后,对PCRF中修改流程的影响没有详细描述;对于用户改变了注册的PCRF后的相关注册流程也没有详细的描述。 As can be seen from Figure 2, this solution is only clear to the user how to obtain the PCRF SPR subscription data, address information for the PCRF stores not described in detail how SPR; for how to delete users in the PCRF policy and charging control information is not described in detail ; for after the SPR If you delete a user policy and charging control subscription information stored, the impact on the PCRF to modify the process has not been described in detail; for the user to change the relevant registration process after the PCRF registered nor described in detail. 另外,当有多个网络为用户服务时,有可能就会有一个用户具有多个用户策略计费控制签约信息,这时,SPR不知道应该将所存储的哪一个用户策略计费控制签约信息提供给PCRF。 In addition, when there are multiple network services for users, it is possible there will be a user with multiple user policy and charging control subscription information, then, SPR does not know which user policy and charging control should be stored subscription information provided to the PCRF. 在23.203协议中,已经明确了在业务承载建立过程中,当SPR修改了存储的用户策略计费控制签约信息后,会将修改后的用户策略计费控制签约 In the 23.203 protocol, it has been identified in the service bearer establishment process, when the SPR modify the user policy and charging control subscription information stored in the user policy and charging control will be modified after the signing

信息发送给对应的PCRF,对应的PCRF再次进行策略计费规则决策后,将决策后的策略计费规则发送给PCEF执行,其具体过程如图3所示:步骤301 、 SPR修改自身存储的用户策略计费控制签约信息后,根据SPR 所保存的修改后的用户策略计费控制签约信息对应的PCRF地址信息,发送用户策略计费控制签约信息修改请求消息到具有PCRF地址信息的PCRF 上,该消息携带修改后的用户策略计费控制签约信息以及UE标识等。 After the information is sent to the corresponding PCRF, the PCRF corresponding policy and charging rule decision again, the decision to send the policy and charging rule to the PCEF performed, the specific process shown in Figure 3: Step 301, SPR modify the user's own stored after the policy and charging control subscription information, subscription PCRF according to the address information corresponding to the user policy and charging control SPR saved modifications, transmitting user subscription policy and charging control information modification request message to the PCRF has PCRF address information, the user policy and charging control message carries the modified subscription information and UE logo. 步骤302、 PCRF接收到该消息后,给SPR发送响应消息。 Step 302, the PCRF receives the message, send a response message to the SPR. 步骤303、 PCRF根据接收到该消息携带的用户策略计费控制签约信息以及已经存在的业务承栽信息,重新进行策略计费决策。 Step 303, PCRF subscription information and business commitments planted existing information according to the received user policy and charging control of the message carried by the re-charging policy decisions. 步骤304、 PCRF将重新决策的策略计费规则携带在策略计费规则请求消息中给PCEF。 Step 304, PCRF re-making policy and charging rules to carry on a policy charging rule request message to the PCEF. 步骤305、 PCEF根据接收到的消息携带的策略计费规则,发起业务承载修改请求到外部节点。 Step 305, PCEF according to the received message carrying the charging rules policy, initiate a service node bearer modification request to the outside. 步骤306、在外部节点完成业务承载修改后,发送业务承载修改响应给PCEF。 Step 306, after the completion of the external service node bearer modification, bearer modification response to the transmission service PCEF. 步骤307、 PCEF发送策略计费规则响应给PCRF。 Step 307, PCEF transmitted in response to a policy charging rule PCRF. 步骤30S、 PCRF检测到业务承载资源变换后,向AF发送通知请求。 Step 30S, PCRF after detecting the traffic bearer resource mapping, send a notification request to AF. 步骤309、 AF发送通知响应给PCRF。 Step 309, AF sends a notification in response to the PCRF. 图3所述的技术方案只是明确了SPR修改用户策略计费控制签约信息以后,向对应的PCRF发送用户策略计费控制签约信息修改消息,并由PCRF 完成相关业务承载的修改过程。 FIG 3 according to the aspect just clear SPR modified after the user subscription policy and charging control information transmitting user subscription policy and charging control information corresponding to the PCRF to modify the message, the modification process is completed by the PCRF associated bearer service. 但是对于如何存储PCRF的地址信息没有详细描述;对于在PCRF如何删除修改前的用户策略计费控制签约信息没有详细描述;对于在SPR如果删除了已存储的修改前的用户签约数据后,对PCRF 中修改流程的影响没有详细描述;对于用户改变了注册的PCRF后的相关注册流程也没有详细的描述。 But does not describe in detail how the PCRF address information for storage; policy and charging control for the user prior to modification in the PCRF how to delete information not described in detail; for the user subscription data in the SPR before the modification if the stored deleted, for PCRF influence of the modification procedure not described in detail; the user changes the registration process related to the PCRF after registration nor described in detail. 综上所述,目前方案中只是提出了包括PCRF从SPR获取用户签约数据信息,以及SPR将修改的用户策略计费控制签约信息发送给PCRF、 PCRF 发起业务承载修改的两个处理过程,对用户策略计费控制签约信息的管理还是不够完善。 In summary, the present embodiment only presents the user PCRF policy and charging control comprises obtaining a user subscription data from the SPR, SPR and the modified subscription information to the PCRF, the PCRF initiates two service bearer modification process, the user management policy and charging control subscription information is still not perfect. 另外,由于PCEF对PCRF的寻址方式是基于网络标识加上UE标识的方法,当同一用户要访问多个网络中的不同业务时,就有可能找到不同的PCRF,这时同一个用户的用户策略计费控制签约信息可能同时需要保存在多个PCRF中,即SPR中可能需要保存多个PCRF的地址信息。 Further, since the PCEF to PCRF addressing network identification is a method based on the UE identity plus, when the same user wants to access a plurality of different services in the network, it is possible to find different PCRF, a user with the user time policy and charging control subscription information may also need to be saved in multiple PCRF, that the SPR may need to save more than the PCRF address information. SPR如何存储一个或多个PCRF地址信息,以及后续在修改或删除用户策略计费控制签约信息时如何根据所存储的PCRF地址信息通知当前为用户提供策略计费服务的PCRF修改或删除用户策略计费控制签约信息,目前也没有叙述。 How SPR storing one or more PCRF address information, and how subsequent PCRF policy and charging current to provide services to users when modifying or deleting a user subscription policy and charging control information according to the address stored PCRF information notification policy modify or delete user count fee subscription information control, there is no narrative. 发明内容有鉴于此,本发明的主要目的在于提供一种在演进网络中管理用户策略计费控制签约信息的方法,该方法能够在演进网络中全面的管理用户签约数据, 实现在SPR中存储PCRF的地址信息或连接标识以及实现PCRF可以正确的获取到对应的用户策略计费控制签约信息。 SUMMARY OF THE INVENTION Accordingly, the main object of the present invention to provide a method of managing a user policy and charging control in an evolved network subscription information, the method to fully manage the user subscription data in the evolved network, implemented in the SPR stored PCRF address information or the connection ID and the PCRF may implement correctly acquired policy and charging control corresponding to a user subscription information. 根据上述目的,本发明的技术方案是这样实现的: 一种在演进网络中管理用户策略计费控制签约信息的方法,该方法包括: 用户策略签约数据库对应用户设备标识存储用户策略计费控制签约信息; 才艮据用户设备标识从用户策略签约数据库获取所存储对应的用户策略计费控制签约信息,用户策略签约数据库根据用户设备标识修改或删除所存储对应的用户策略计费控制签约信息,根据用户设备标识存储、修改或删除当前4吏用用户策略计费控制签约信息的策略和计费规则功能实体的地址信息或连接标识。 According to the above-described object, the technical solution of the present invention is implemented as follows: a management user policy and charging control in an evolved network subscription information, the method comprising: a user subscription policy database storing a user identifier corresponding to user equipment subscription policy and charging control information; Gen only acquires data stored in a user equipment identifier corresponding to the user from the user policy and charging control policy subscription database subscription information, user subscription database to modify the policy and charging control policy or subscription information of a user deletes the stored identifier corresponding to the user equipment, according to the user equipment identity store, modify, or delete the current address information or connection ID 4 officials subscription information with user policy and charging control policy and charging rules function entity. 所述获取用户策略计费控制签约信息,存储策略和计费规则功能实体地址信息或连接标识的过程为:策略和计费规则功能实体向用户策略签约数据库发送携带用户设备标识策略计费规则请求消息; Obtaining the user subscription policy and charging control information stored policy and charging rules function entity address or connection identification process: policy and charging rules function entity message carrying a user equipment identifier policy charging rule request to the user subscription policy database news;

步骤1009、 SPR发送用户策略计费控制签约信息已删除响应消息给PCRF。 Step 1009, SPR policy and charging control transmitting user subscription information has been deleted in response to the message PCRF. 图11为本发明PCRF通知SPR删除所存储的PCRF地址信息或连接标识的方法实施例三流程图,该方法在PCRF中删除一个用户的用户策略计费控制签约信息时,通过断开连接的指示来通知SPR,其具体步骤为:步骤1101、在PCRF中删除该用户的用户策略计费控制签约信息。 11 of the present invention PCRF notifies SPR PCRF deletes the stored address information or the identification method of connecting three flowchart embodiment, the method to delete a user in the PCRF policy and charging control of the user subscription information, by indicating the disconnected the SPR to notify, including the following steps: step 1101, the user deletes the user subscription policy and charging control information in the PCRF. 步骤1102、 PCRF发送该用户连接断开指示消息到SPR。 Step 1102, PCRF transmits the disconnection indication message to the user SPR. 如果PCRF与SPR之间采用订阅通知的工作方式,则PCRF需要判断该用户是否向SPR签订订阅通知,如果是,则PCRF需要向SPR发送该用户连接断开指示消息;否则PCRF不向SPR发送该用户连接断开指示消息。 If the notification subscription between the PCRF and the SPR work, the PCRF needs to determine whether the user entered into the SPR notification subscription, if so, the PCRF needs to send the message to the user indicating disconnection SPR; otherwise not be sent to the PCRF SPR user disconnect indication message. 步骤1103、 SPR删除所存储的对应于发起连接断开指示消息的PCRF 的地址信,包、或连接标识。 PCRF address signal in step 1103, SPR deletes the stored corresponding to initiate a disconnection indication message, packet, or connection identification. 步骤1104、 SPR发送该用户连接断开响应消息到PCRF,删除与发送该用户连接断开指示消息的相关连接。 Step 1104, SPR transmits the disconnection response message to the user PCRF, and sends the relevant delete connected to the disconnection indication message to the user. 第四个处理流程有三个主要的实现方法,以下进行详细说明。 The fourth three main process flow implementation method, described in detail below. 实现方法一:首先,UE发起附着操作到移动管理实体(MME) , MME发送注册请求消息到归属用户服务器(HSS),在注册请求消息中指明这个注册请求消息是UE的附着操作以及UE标识等信息。 Implementation A: First, UE initiates the attaching operation to the mobility management entity (MME), MME sends a registration request message to the home subscriber server (HSS), indicating that registration in the registration request message, the request message is a UE attaching operation and UE identification, etc. information. 其次,HSS接收到该注册请求消息后,判断为UE当前提供服务的MME 是否更改,如果是,则发送通知消息到SPR;如果否,则不发送通知消息到SPR,该通知消息包括UE标识,其指明是附着操作。 Secondly, the HSS receives the registration request message, the UE determines the current serving MME whether to change, if yes, sending a notification message to the SPR; if not, not send a notification message to the SPR, the notification message comprises a UE identity, attaching operation which is specified. 再次,SPR接收到通知消息,检测是否保存对应该UE标识的用户策略计费控制签约信息的PCRF地址信息或连接标识,该PCRF地址信息或连接标识还对应于当前为UE提供服务的网络标识,如果有,则发送取消注册请求消息到该一个或多个PCRF ( SPR中有可能保存多个PCRF地址信息); Again, the SPR receives the notification message, detect whether to save the address information or the connection identification PCRF information to a user subscription policy and charging control should UE identifier, the address of the PCRF or the connection identification information corresponds to the network identifier to the currently serving the UE, If so, then sends a cancel registration request message to the one or more PCRF (in the SPR is possible to preserve a plurality PCRF address information);

否则,则不发送取消注册请求消息。 Otherwise, cancel the registration request message is not sent. 取消注册请求消息中包含UE标识以及其他可能信息,SPR删除保存的对应该UE标识的用户策略计费控制签约信台最后,该一个或多个PCRF接收到SPR的取消注册请求消息后,根据UE标识以及其他可能信息删除该UE标识对应的在PCRF中的用户策略计费控制签约信息,如果PCRF检测到还存在对应的业务承栽,则PCRF删除这些对应的业务承载。 Cancel registration request message containing the UE ID and possibly other information, the user SPR deletes the stored policy and charging control subscription identifier to the UE and the last letter units, the one or more received PCRF SPR cancel registration request message, according to the UE identification and other information may be deleted by the UE corresponding to the user identifier in the PCRF policy and charging control subscription information, if there is detected PCRF service corresponding bearing plant, the PCRF to delete the corresponding service bearer. 在该实现方法中,MME和用户面实体(UPE)分离还是合并无关。 In this implementation process, MME and a user plane entity (UPE) separated independent or combined. 采用该实现方法,可以删除在附着操作流程前一些PCRF所緩存的用户策略计费控制签约信息。 With this implementation, attachment can be deleted before the operation flow of some of the buffered user PCRF policy and charging control subscription information. 采用该实现方法,可以保证在一些异常情况下实现PCRF 中存储的用户策略计费控制签约信息的删除,如当业务承载删除时,而在PCRF上的用户签约数据没有被正确删除的情况。 With this implementation, it is possible to ensure the realization PCRF stored in some unusual circumstances the user subscription policy and charging control information is deleted, such as when the traffic bearer deletion, and the user subscription in case the PCRF data is not correctly removed. 实现方法二:首先,UE发起附着操作到MME/UPE上。 Implementation two: First, UE initiates the attaching operation to the MME / UPE. 其次,在建立缺省业务承载过程中或业务缺省承载建立完成以后,PCEF (位于UPE或锚(Anchor ))发送注册请求消息到UE切换到的PCRF上, 在注册请求消息中指明是附着操作,以及携带UE标识等信息。 Secondly, the process of establishing the default bearer service or service default bearer establishment is completed after the PCRF, the PCEF (or anchor located UPE (Records)) send a registration request message to the UE to handover, specified in the registration request message is attaching operation and carries the UE identification information. 再次,UE切换到的PCRF接收到来自PCEF的注册请求消息后,发送用户策略计费控制签约信息获取请求消息到SPR,在该请求消息中指明是附着操作,以及携带UE标识等信息。 Again, the UE is switched to the PCRF receives the registration request message from the PCEF, transmitting user subscription policy and charging control information acquisition request message to the SPR, the request message is indicated in the attaching operation, and carrying UE identity information. 最后,SPR接收到请求消息,且检查到有附着操作的指示后,检测是否保存有对应该UE标识的PCRF地址信息或连接标识,如果有,则发送取消注册请求消息到对应该UE标识的一个或多个PCRF (SPR中有可能保存多个PCRF地址信息或连接标识);否则,则不发送取消注册请求消息。 After the last, the SPR receives the request message, and checks the instruction has attaching operation of detecting whether the data to PCRF address information or the connection identification should UE identifier, if so, it sends a cancel registration request message to a pair should UE identity PCRF or more (in the SPR is possible to preserve a plurality of address information or the connection identification PCRF); otherwise, the cancel registration request message is not sent. SPR 删除保存的对应该UE的用户策略计费控制签约信息。 User policy and charging control SPR should delete saved on UE subscription information. 该一个或多个PCRF 接收到SPR的取消注册请求消息后,根据UE标识以及其他可能信息删除对应该UE的在PCRF中的用户策略计费控制签约信息,如果PCRF^r测到还 The received one or more PCRF SPR cancel registration request message, the UE according to the subscription ID and other information that may be deleted to the user of the UE in the PCRF policy and charging control information, if the measured further PCRF ^ r

存在对应的业务承载,则PCRF删除这些对应业务承载。 There is a corresponding bearer service, the PCRF to delete the corresponding service bearer. 实现方法三:首先,AF或PCEF发起业务承栽建立过程与PCRF进行交互,在文互过程中将业务承栽的UE标识以及相关信息发送给PCRF。 Implemented method three: First, AF or PCEF initiates a service setup procedure bearing plant interaction with PCRF, the PCRF transmits the message interaction in the process of business to grow and UE identification information. 其次,PCRF检测到没有具有UE标识的用户策略计费控制签约信息, 向SPR发送荻取用户策略计费控制签约信息请求消息,该消息携带UE标识以及网络标识等信息;如果PCRF存在具有UE标识的用户策略计费控制签约信息,则不向SPR发送获取用户策略计费控制签约信息请求消息。 User subscription policy and charging control information Next, the PCRF is not detected with the UE identifier is sent to the user to take SPR Di subscription policy and charging control information request message, the message carries the UE identifier and the network identification information; PCRF if the UE has identified the presence of user subscription policy and charging control information is not transmitted to the SPR to obtain the user subscription policy and charging control information request message. 再次,SPR根据接收到的请求消息携带的UE标识以及网络标识检测是否有对应的PCRF地址信息或连接标识,如果有,则发送取消注册消息到注册消息到具有该PCRF地址信息或连接标识的PCRF上。 Again, the SPR whether a corresponding PCRF address information or connection identifier according to the UE identifier and the network identifier detected received request message, and if so, sends a cancel registration message to the registration message to have the PCRF address information or the connection identification of the PCRF on. 取消注册消息中包括UE标识以及为用户提供服务的网络标识等信息,同时SPR删除该PCRF 地址信息或连接标识。 Cancel the registration message includes a UE ID and network identification information for the user to provide the service, while SPR delete the PCRF address information or connection ID. 值得注意的是,如果该PCRF与具有该UE标识的用户的多个提供服务的网络标识相关联,并存在对应的业务承载,这时只删除与所发起取消注册请求消息的提供服务的网络标识对应的PCRF地址信息或连接标识,而对于为用户提供服务的其他网络标识对应的PCRF地址信息或连接标识不进行删除。 Notably, a plurality of network identification associated with the user identifier of the UE, if the service having a PCRF, and there is a corresponding bearer service, and then only remove the initiated registration cancellation request message service network identification PCRF information corresponding to the address or the connection identification, and other network identifier corresponding to the connection identification information or address PCRF to provide users with services without erasing. 最后,PCRF接收到取消注册消息后,根据该消息携带的UE标识以及为网络标识,删除对应的用户策略计费控制签约信息;如果PCRF检测到还存在与用户策略计费控制签约信息对应的业务承载,则PCRF删除这些对应的业务承载。 Finally, the PCRF receives Unregister message, the message carrying the subscription information according to the UE identifier and the network identifier corresponding to a user delete policy and charging control; if there is detected PCRF information corresponding to the user service subscription policy and charging control bearer, the PCRF to delete the corresponding service bearer. 值得注意的是,PCRF还可能继续保存与其他为用户服务的网络标识相关的用户策略计费控制签约信息。 It is noteworthy that, PCRF may continue to hold other related network identity services for users of the user policy and charging control subscription information. 以下举几个具体实施例分别说明这三个实现方法。 Here are some specific examples illustrate the three-implemented method. 实现方法一的具体实施例图12为本发明由HSS通知SPR,并且由SPR发起注册取消操作到PCRF Implementation Example FIG. 12 a specific embodiment of the present invention, the notification by the SPR HSS, and initiates a registration cancellation from the SPR to the PCRF
