Description
Technical field
The present invention relates to communication technical field, relate in particular to the route treatment technology.
Background technology
Now, the telecommunication network environment numerous and complicated be to guarantee the reliable operation of communication network, need carry out accurately the professional and professional shared resource in the communication network, in time, comprehensively control.Wherein, business being carried out strategy is one of control important in the above-mentioned control with the control of chargeing.
At 3GPP (3rd Generation Partnership Project, the standardized partnership projects of 3G (Third Generation) Moblie) in the system, the controlled function of strategy and charging is by PCC (Policy and Charging Control, the strategy and the control of chargeing) the framework specific implementation, this framework mainly comprises PCRF (Policy and ChargingRules Function, strategy and charging rule functions) entity, PCEF (Policy and ChargingEnforcement Function, strategy and charge execution function) entity, BBERF (Bearer Binding andEvent Report Function, bearing binding and reporting events function) entity etc.Wherein the PCRF entity is the core of PCC structure system, and the PCC rule and formulation QOS (Quality of Service, the service quality) rule that provide based on business data flow are provided; The PCEF entity generally is positioned on the gateway of network, GPRS (General Packet Radio Service for example, GPRS) (the Gateway GPRS Support Node of the GGSN in the network, Gateway GPRS Support Node) or SAE (SystemArchitecture Evolution, System Architecture Evolution) (the Packet Data NetworkGateway of the PDN GW in the network, grouped data network gateway) etc., be mainly used in the execution of PCC rule; The BBERF entity generally is positioned on the IP IAD, Serving GW (the Serving Gateway in the SAE network for example, gateway) or the MAG in the non-3GPP network (Mobile Access Gateway, Mobile Access Gateway), be mainly used in the execution of QOS rule.Wherein the PCRF entity is IP-CAN (IP Connectivity Access Network IP is communicated with Access Network) session with session between the PCEF entity; Session between PCRF entity and the BBERF entity is a gateway control session.
Under user's roaming scence, communication network is divided into HPLMN (Home Public Land MobileNetwork usually, belong to public land mobile communication network) and VPLMN (Visit Public Land MobileNetwork, visit public land mobile communication network) two parts.Wherein VPCRF (Visit PCRF, visit strategy and charging rule functions) entity and BBERF entity are positioned at VPLMN; Entity is positioned at HPLMN to HPCRF (Home PCRF, ownership strategy and charging rule functions), if the PCEF entity is positioned at HPLMN, user route mode is the local routing mode; If the PCEF entity is positioned at VPLMN, then user route mode is that visited network inserts routing mode.
The prior art scheme is under roaming condition, and VPCRF entity and HPCRF entity are different according to user route mode, carry out different operations.When user route mode was the local route, the HPCRF entity comprised the QOS rule in gateway control session foundation is receiveed the response; Insert routing mode for visited network, the HPCRF entity does not comprise the QOS rule in gateway control session foundation is receiveed the response.For the local routing mode, any gateway control session message that the VPCRF entity will be received all is transmitted to the HPCRF entity; Insert routing mode for visited network, the VPCRF entity is revised message with gateway control session and is terminated in this locality, is not transmitted to the HPCRF entity.
But VPCRF entity and HPCRF entity are to judge user route mode according to gateway control session message and the IP-CAN conversation message received.For example, if the HPCRF entity by and PCEF between interface receive the IP-CAN conversation message, then the HPCRF entity judges that user route mode is the local routing mode; If the HPCRF entity by and the VPCRF entity between interface receive the IP-CAN conversation message, then the HPCRF entity judges that user route mode is that visited network inserts routing mode; Accordingly, if the VPCRF entity by and PCEF between interface receive the IP-CAN conversation message, then the VPCRF entity judges that user route mode is that visited network inserts routing mode; If when the VPCRF entity receives that from the HPCRF entity gateway control session is revised message, still do not receive corresponding IP-CAN conversation message, then the VPCRF entity judges that user route mode is the local routing mode.
Fig. 1 is in the prior art, and user route mode is that visited network inserts under the routing mode, gateway control session set up and the IP-CAN session set up flow process:
Step 101, BBERF entity send gateway control session to the VPCRF entity and set up message;
Step 102, VPCRF entity are transmitted gateway control session to the HPCRF entity and are set up message;
Step 103, HPCRF entity send gateway control session foundation to the VPCRF entity and receive the response;
Gateway control session comprises the QOS rule that the HPCRF entity is formulated in setting up and receiveing the response.
Step 104, VPCRF entity are set up to BBERF entity forwarding gateway control session and are receiveed the response;
Step 105, BBERF entity send mobile IP message to the PCEF entity;
The BBERF entity can send mobile IP message to the PCEF entity after receiving that gateway control session foundation is receiveed the response, and triggers the PCEF entity and sets up corresponding IP-CAN session.
Step 106, PCEF entity send the IP-CAN session to the VPCRF entity and set up message;
The VPCRF entity by and the PCEF entity between interface receive the IP-CAN conversation message, judge user route mode and be visited network and insert routing mode.
Step 107, VPCRF entity are transmitted the IP-CAN session to the HPCRF entity and are set up message;
The HPCRF entity by and the VPCRF entity between interface receive the IP-CAN conversation message, judge user route mode and be visited network and insert routing mode.
Step 108, HPCRF entity are set up to VPCRF entity answer IP-CAN session and are receiveed the response;
Step 109, VPCRF entity are set up to PCEF forwarding IP-CAN session and are receiveed the response.
The PCEF entity receives that the IP-CAN session is set up and receives the response that the IP-CAN session is set up.
In research and practice process to prior art, the inventor finds that there is following problem in prior art:
The method that the prior art route is handled need be when IP-CAN sets up, the PCRF entity could be judged user route mode by receiving message, cause when gateway control session is set up, the PCRF entity can't be judged user route mode, also just can't clear and definite message processing logic.For example, when user route mode inserts routing mode for visit, the VPCRF entity will not need the gateway control session forwards of HPCRF entity handles to give the HPCRF entity, not realize that gateway control session to the hiding of HPCRF entity, has also strengthened the information processing load of HPCRF entity simultaneously.

The BBERF entity receives the user and inserts message, different according to system and agreement, and the type that the user inserts message can have multiple.The user inserts the address that message can comprise user profile, PCEF entity, the indication information that can also include user route mode.
If the user inserts the indication information that includes user route mode in the message, then the BBERF entity directly obtains user route mode according to the indication information of user route mode; If the user inserts the indication information that does not adhere to user route mode in the message, then can be according to the address of PCEF entity, user's information routing modes such as user ID or station address are judged, obtain user route mode according to the result who judges.
The concrete mode of notice can be that the indication information of user route mode is set up in the message attached to gateway control session, described gateway control session is set up message be sent to the VPCRF entity.
In the concrete application of network system, judge the difference of main body according to user route mode, flow process is initiated the difference of entity, and the method that embodiment of the invention route is handled realizes in different ways, below in conjunction with different situations the embodiment of the invention is further specifically described.
Embodiment two,
The judgement of user route mode is carried out at the BBERF entity in the present embodiment, and referring to Fig. 3, the embodiment of the invention two gateway control session are set up flow chart, and detailed process is as follows:
The user that step 301, BBERF entity receive the network entity transmission inserts message;
When user network inserted, network entity sent the user to the BBERF entity and inserts message.Described network entity can be that gateway is selected entity, also can be the network entity of selecting entity to link to each other with gateway.Described gateway selection entity can be HSS (the Home Subscriber Server in the SAE network, home signature user server), MME (Mobility Management Entity, Mobility Management Entity), perhaps AAA (Authentication Authorization Accounting, authenticated/authorized/charging) server etc.Described user inserts message: if network entity is the MME in the SAE network, then the user to insert message can be to set up the default bearing request message between MME and the BBERF place gateway, gateway selecting function can be carried out by MME, also can carry out by HSS, if carry out gateway selecting function by HSS, then HSS can also comprise that with the PCEF place gateway address of selecting the user route mode indication sends to MME; If network entity is an aaa server, then the user to insert message can be authentication and authorization messages between aaa server and the non-3G network IAD.Described user inserts the address that can comprise the PCEF entity in the message, can also include station address and/or user ID etc.Described user ID can be IMSI (the International Mobile Subscriber Identity in the 3GPP network, international mobile subscriber ID), TMSI (Temporary Mobile Subscriber Identities, temporarily moved subscriber ID), GUTI (Globally Unique Temporary Identity, whole world unique temporary identity), NAI (NetworkAccess Identifier, network access Identifier) etc., described PCEF entity can be the PDNGW in the SAE network, the GGSN in the GPRS network etc.
Step 302, BBERF entity are judged user route mode;
The BBERF entity can be the network entity that MAG (Mobile Access Gateway, Mobile Access Gateway) in Serving GW in the SAE network, the non-3GPP network etc. has the BBERF function.
The BBERF entity can be judged the user according to user ID and be in visited network, and described user ID can be to be carried at the user to insert in the message, also can be to be kept in the BBERF entity.Judge PCEF entity network of living in according to the address of PCEF entity, concrete judgment mode can be that the address with the address of PCEF entity and BBERF entity compares, perhaps the address field scope with PCEF physical address and visited network or home network compares, and judges the residing network of PCEF entity according to comparative result.For example, when the user is in visited network, if the PCEF entity is in visited network, then user route mode is that visited network inserts routing mode; If the PCEF entity is in home network, then user route mode is the local routing mode.
Step 303, BBERF entity send gateway control session to the VPCRF entity and set up message;
Described gateway control session is set up message and can be used for notifying VPCRF entity with user route mode.Concrete advice method can be to set up the indication information that adheres to user route mode in the message in described gateway control session, and described indication information is in order to the routing mode notice VPCRF entity with the user.Specifically can be to be visited network when inserting routing mode only, set up the Warning Mark that carries user route mode in the message in gateway control session in user route mode.Can certainly be when various user route mode, set up the Warning Mark that carries user route mode in the message in gateway control session.The mode of user route mode indication can be that gateway control session is set up an indicating bit that adheres in the message, perhaps directly adheres to user route mode etc.
If it is the local routing mode that sign is represented user route mode, perhaps there is not the situation of routing mode sign, enter step 304; If it is that visited network inserts routing mode that indication information shows user route mode, enter step 306.
Step 304, VPCRF entity are transmitted gateway control session to the HPCRF entity and are set up message;
After the VPCRF entity receives that gateway control session that the BBERF entity sends over is set up message, set up the indication information acquisition user route mode that message is carried according to gateway control session, preserve user route mode, in user route mode is the local route, when perhaps not having the situation of routing mode sign, gateway control session is set up forwards to the HPCRF entity.
Step 305, HPCRF entity are set up to VPCRF entity answer gateway control session and are receiveed the response;
The HPCRF entity has been received that gateway control session that the VPCRF entity sends is set up and has been receiveed the response, show that user route mode is the local route, then replying gateway control session foundation to the VPCRF entity receives the response, carry the QOS rule of carrying out for the BBERF entity in this message, described QOS rule is formulated by the HPCRF entity.
Step 306, VPCRF entity send gateway control session foundation to the BBERF entity and receive the response.
Insert routing mode if user route mode is a visited network, the VPCRF entity is set up to BBERF entity answer gateway control session and is receiveed the response, and carries the QOS rule that the VPCRF entity is formulated in the described message; If user route mode is the local routing mode, the gateway control session that the VPCRF entity sends over to BBERF entity forwarding HPCRF entity is set up and is receiveed the response.
As can be seen, the flow process that step 303 is set up for the gateway control session under the PCC framework to step 306, if user route mode is the local routing mode, then gateway control session is set up flow process and is comprised that step 303 is to step 306; Insert routing mode if user route mode is a visited network, then gateway control session is set up flow process and is included only step 303, step 306.
As can be seen, when the present embodiment method is visited network access routing mode in user route mode, the VPCRF entity is hidden the gateway control session related news to the HPCRF entity, do not transmit the gateway control session related news to the HPCRF entity, simplify message interaction process, reduced the data and the information processing load of HPCRF entity.
