In step 203, the DRA judges whether the user belongs to the region according to the user identifier. If the user belongs to the local area, executing step 204; if the user does not belong to the local area, step 205 is executed.
In step 204, the DRA determines a corresponding PCRF according to the user identifier and the APN in the Rx session message, and routes the Rx session message to the PCRF, completing the flow of the routing agent method of the present invention.
In step 205, the DRA roams the Rx session message to the DRA of the user's home region. After receiving the Rx session message, the DRA in the home area of the user starts to execute from step 201, so as to determine the PCRF which the user belongs to in the home area.
In step 206, the DRA determines the user home PCRF based on the association information stored by the DRA according to the public network IP address information and the private network IP address information in the Rx session message, and routes the Rx session to the corresponding PCRF.

A flow diagram of yet another embodiment of the routing agent method of the present invention is shown in fig. 3.
In step 301, the DRA acquires an Rx session message.
In step 302, the DRA determines whether the Rx session message includes a user identifier. If the user identifier is included, executing step 303; if the user identification is not included, step 306 is executed.
In step 303, the DRA determines whether the user belongs to the region according to the user identifier. If the user belongs to the local area, go to step 304; if the user does not belong to the local area, step 305 is executed.
In step 304, the DRA determines the corresponding PCRF according to the user identifier and the APN in the Rx session message, and routes the Rx session message to the PCRF, completing the flow of the routing agent method of the present invention, without executing other steps in this embodiment.
In step 305, the DRA roams the Rx session message to the DRA in the user's home area, and the DRA does not perform any further steps in this embodiment.
After receiving the Rx session message, the DRA in the home area of the user starts to perform step 301, so as to determine the PCRF which the user belongs to in the home area.
In step 306, the DRA determines the IP domain identifier corresponding to the user, and determines whether the IP domain identifier belongs to the area. If the IP domain identifier does not belong to the local area, executing step 307; if the IP field ID belongs to the local area, go to step 308.
In step 307, the DRA routes the Rx session to the upper level DRA, and the present DRA does not continue to perform other steps in this embodiment.
After receiving the Rx session message, the upper level DRA performs the steps of this embodiment from step 301 until determining the PCRF to which the user belongs.
In step 308, the DRA determines whether the user belongs to the local area, and if the user is determined to belong to the local area, step 309 is executed; if the user does not belong to the local area, step 310 is executed.
In step 309, the DRA determines the PCRF of the user according to the private network IP address information of the user, and further routes the Rx session message to the corresponding PCRF, thereby completing the procedure of this embodiment.
In step 310, the DRA acquires the user identifier and the APN information according to the private network IP address information of the user, fills the user identifier and the APN information into the Rx session message, and forwards the modified Rx session message to the higher-level DRA, which does not execute any other flow of this embodiment. In one embodiment, the padding of the user identity and APN information into the Rx session message may be: and filling the user identification into a Subscription-Id AVP field in the Diameter AAR message, and filling the APN information into a Called-Station-Id AVP field.
After receiving the Rx session message, the upper level DRA starts to execute from step 301 until determining the corresponding PCRF.
By the method, the DRA can realize routing addressing and session binding under the conditions of multiple APNs, multiple PCRFs and multiple PCEF, and the PCRF to which the user belongs can be determined according to the method under the conditions that the Rx session message includes or does not include the user identifier, whether the user is located locally or not and whether the user belongs to locally or not, so as to realize session binding.
In an embodiment, the DRA may map the public network IP address in the Rx session message to an IP domain identifier, and further determine whether the IP domain identifier is a domain identifier of the area. If the IP domain identification is the domain identification of the local area, the public network IP address is the address of the local area, and the user is located in the local area; if the IP domain identifier is not the domain identifier of the region, the user is not located in the region, and the position of the user needs to be judged by the superior DRA.
By the method, the DRA can judge whether the user is located locally according to the IP address of the public network of the user, and further can determine whether the user PCRF is continuously searched by the DRA or is handed to a superior DRA for execution, so that the corresponding PCRF can be searched when the user is in a home location or roaming location state.
In an embodiment, the DRA further stores a corresponding relationship between the PCEF identifier and the IP domain identifier, and the DRA is capable of mapping the public network IP address in the Rx session message to the IP domain identifier, and then determining the PCEF identifier corresponding to the IP domain identifier based on the corresponding relationship between the PCEF identifier and the IP domain identifier.
By the method, when the Rx session message does not comprise the user identifier, the PCEF identifier can be obtained according to the IP address information of the public network of the user, so that the PCRF identifier of the user can be conveniently obtained by matching with the IP address information of the private network of the user.
In an embodiment, when a user is online, the DRA may generate and store user association information, where the association information may include a user private network IP address, a PCEF identifier, a user identifier, and a PCRF identifier in a Gx session.
By the method, the DRA can store the user association information when the user is online, so that after the Rx session message is received, the corresponding PCRF identifier can be searched based on the association information according to the information in the Rx session message as an index, and the session binding is realized.
A schematic diagram of one embodiment of a routing proxy node of the present invention is shown in fig. 4. The message acquiring module 401 may acquire an Rx session message and transmit the Rx session message to the local area user determining module 402. The local area user determining module 402 determines whether the user is a local area user according to the user identification information in the Rx session message; if the user is a local user, the execution module 403 acquires a corresponding PCRF according to the user identifier and the APN, and routes the Rx session message to the corresponding PCRF.
The DRA can determine the PCRF to which the user belongs according to the user identifier and the APN information in the obtained Rx session message, so that the Rx session message can be sent to the corresponding PCRF; particularly, in a multi-APN scene, even if multiple sets of PCRF and PCEF exist in the area, the DRA of the invention can also correctly realize PCRF search so as to realize session binding.
In one embodiment, when the local area user determining module 402 determines that the user is not the local area user, the executing module 403 routes the Rx session message to the upper level DRA. The upper level DRA message obtaining module 401 obtains Rx session message, and the local area user determining module 402 performs the step of determining whether the user is located in the local area according to the public network IP address.
Under the condition that the user is not the local area user, the DRA can route the Rx session message to the upper level DRA for processing, and the corresponding PCRF is ensured to be searched.
A schematic diagram of another embodiment of a routing proxy node of the present invention is shown in fig. 5. The message acquiring module 501 can acquire an Rx session message and transfer the Rx session message to the identifier determining module 502. The identity determination module 502 can determine whether the Rx session message includes a user identity.
If no user identification is included, the execution module 504 is activated. The execution module 504 determines a corresponding PCRF based on the association information stored by the DRA according to the public network IP address and the private network IP address in the Rx session message, and routes the Rx session message to the PCRF.
If the user identifier is included, the local area user determination module 503 is activated. The local area user determining module 503 determines whether the user is a local area user according to the user identifier information in the Rx session message. If the user is a local user, the execution module 504 acquires the corresponding PCRF according to the user identifier and the APN, and routes the Rx session message to the corresponding PCRF. When the local area user determining module 503 determines that the user is not the local area user, the executing module 504 routes the Rx session message to the upper level DRA. The message acquiring module 501 of the upper level DRA acquires the Rx session message, and activates the identifier determining module 502 thereof to execute the operation.
Such DRA can determine whether the Rx session message includes user identification information; when the Rx session message does not include the user identification information, the DRA can determine the PCRF according to the user public network IP address and the user private network IP address, and can route the Rx session message to the corresponding PCRF to realize the binding of the session.
In an embodiment, when the identifier determining module 502 determines that the Rx session message does not include the user identifier, the executing module 504 determines whether the IP domain identifier corresponding to the user public network IP address in the Rx session message is located in the local area. If the IP domain identifier does not belong to the area, the Rx session is routed to the upper level DRA, and after receiving the Rx session message, the message obtaining module 501 of the upper level DRA may activate the identifier determining module 502 to perform the next operation. If the execution module 504 determines that the user IP domain identifier belongs to the local area, it continues to determine whether the user private network IP address in the Rx session message is located in the local area. If the private network IP address is located in the local area, the user belongs to the local area, the PCRF of the user is determined according to the private network IP address information of the user, and the Rx session message is routed to the corresponding PCRF. If the private network IP address is not located in the local area, the user identifier and the APN information are obtained according to the private network IP address information of the user, the Rx session message is filled in the Rx session message, the modified Rx session message is forwarded to the upper-level DRA, the message obtaining module 501 of the upper-level DRA can activate the identifier judging module 502 to carry out the next operation after receiving the Rx session message, and the upper-level DRA can obtain the corresponding PCRF according to the user identifier and the APN.
The DRA can judge the position of the user according to the public network IP address of the user under the condition that the Rx session message does not include the user identifier, determine the attribution of the user according to the private network IP address information, and further determine the PCRF of the attribution of the user so as to realize session binding.
A schematic diagram of yet another embodiment of a routing proxy node of the present invention is shown in fig. 6. The structure and function of the message obtaining module 601, the identification judging module 602, the local area user judging module 603 and the executing module 604 are similar to those in fig. 5. The DRA may further include an association information module 605 configured to generate and store association information when the user is online, where the association information includes a user private network IP address, a PCEF identifier, a user identifier, and a PCRF identifier.
The DRA can store user association information when a user is online, so that after an Rx session message is received, the information in the Rx session message can be used as an index, and a corresponding PCRF identifier can be searched based on the association information, so that session binding is realized.
In an embodiment, the DRA may map the public network IP address in the Rx session message to an IP domain identifier, and further determine whether the IP domain identifier is a domain identifier of the area. If the IP domain identification is the domain identification of the local area, the public network IP address is the address of the local area, and the user is located in the local area; if the IP domain identifier is not the domain identifier of the region, the user is not located in the region, and the position of the user needs to be judged by the superior DRA.
The DRA can judge whether the user is located locally or not according to the IP address of the public network of the user, and further can determine whether the DRA continues to execute the PCRF search of the user or is handed to a higher-level DRA for execution.
In an embodiment, as shown in fig. 6, the DRA further includes a configuration module 606 configured to store a correspondence between the PCEF identifier and the IP domain identifier. The DRA can map the public network IP address in the Rx session message into an IP domain identifier, and then determines the PCEF identifier corresponding to the IP domain identifier based on the corresponding relation between the PCEF identifier and the IP domain identifier.
Thus, the DRA can acquire the PCEF identifier according to the IP address information of the public network of the user under the condition that the Rx session message does not include the user identifier, thereby being convenient for acquiring the PCRF identifier of the user by matching with the IP address information of the private network of the user.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
