Embodiments of the invention

The detailed description will be made below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

As shown in FIG. 1 , after the application server AS A receives the invitation (Invite) message submitted by the sender user (User A), the application server AS A forwards the Invite message to the IP multimedia subsystem. IP Multimedia Subsystem A, IMS A), then sends the Invite message to the AS B to which the receiver user User B belongs through the IMS B. After the Invite message is forwarded to the IMS B by the AS B, the Invite message is sent to the User B through the IMS B. . Similarly, the same steps are performed for the 180 Ringing response message, the 200 OK message, and the User A ACK message returned by User B. Even if the sender user and the receiver user belong to the same AS, there is a lot of these signalings. Therefore, a large amount of traffic overhead is inevitable and the network efficiency is reduced.

In order to solve the defects of the above standard routing manner, the implementation of the rich communication suite RCS in the embodiment of the present invention The system communication method establishes a session by using a short circuit method when the sender user and the receiver user belong to the same application server, which greatly reduces the signaling interaction process, reduces the user's traffic consumption, and reduces the network burden. , improve processing efficiency.

As shown in FIG. 2, a method for implementing communication of a rich communication suite RCS system according to an embodiment of the present invention is applied to an application server, including:

Step 11: Receive an invitation message forwarded by the core network device.

Step 12: Determine, according to the pre-stored local user information, whether the sender user and the receiver user of the invitation message are both local users, where the local user refers to a user belonging to the application server, and the local user information The identification information of the local user and the core network device information accessed by the local user are recorded therein;

Step 13: When it is determined that the sender user and the receiver user are both local users, acquiring core network device information accessed by the receiver user;

Step 14: Send the invitation message to the corresponding core network device according to the obtained core network device information, so that the core network device directly sends the invitation message to the receiver user.

The method for implementing communication of the rich communication suite RCS system in the embodiment of the present invention establishes a session by using a short circuit by means of a sender user and a receiver user belonging to the same application server, thereby reducing traffic overhead, improving network utilization and processing. Efficiency and reduced costs.

At this time, when the receiver user is a local user, the core network device information accessed by the receiver user is obtained, where the IP address and port number of the core network device are used, so that the application server can quickly find the corresponding core network device. And send the invitation message to the core network device, ensuring the smooth establishment of the session and improving the processing efficiency.

In order to enable the application server to determine whether the user who established the session is a local user, local user information needs to be integrated. Therefore, the method for implementing communication of the rich communication suite RCS system in the embodiment of the present invention may further include:

Step 15: After receiving the registration message forwarded by the core network device, the user information of the registered user is stored as local user information.

At this time, by recording the relevant information of the user when the user registers, data support is provided for the judgment of the local user, ensuring that the short circuit is accurately performed by the session.

As shown in FIG. 3, a signaling procedure for generating local user information is provided by the method in the embodiment of the present invention. After receiving the Register message of the User A forwarded by the core network IMS (step 111 and step 112), the application server AS sends a message of updating the user information (Update UserInfo) to the local user database (User-DataBase) (step 113). Then, the user information of User A is stored, and after the storage is completed, a message of 200 OK is returned to the user (steps 114 and 115). By updating the user data to the local database when the user registers, the data basis for the local user's judgment is provided, and the accurate judgment of the local user is ensured, thereby ensuring whether the short circuit is accurately judged by the session.

In the embodiment of the present invention, the step of the foregoing step 12 may include:

Step 121: Obtain identification information of the sender user and the receiver user respectively.

Step 122: Query, according to the identifier information of the sender user and the receiver user, the user information of the sender user and the receiver user in the pre-stored local user information;

Step 123: If the user information of the sender user and the receiver user is queried in the local user information, it is determined that the sender user and the receiver user are both local users.

At this time, the user information of the user can be quickly found in the local user information to determine whether the user is a local user. Here, based on the identification information of the sender user and the receiver user, the local user information is queried whether there is user information of the sender user and the receiver user, thereby determining whether the sender user and the receiver user are local users. It is guaranteed that the short circuit is accurately judged by the session and the processing efficiency is improved.

The identification information of the local user may be a user name or a mobile phone number.

The method for implementing communication of the rich communication suite RCS system according to the embodiment of the present invention, if the short circuit method is adopted, after the application server determines that the sender user and the receiver user of the invitation message belong to the application server, the local user information may be used according to the local user information. The IP address and port of the core network device accessed by the receiver user are obtained and sent to the core network, and the core network directly forwards the invitation message to the receiver user. Similarly, for the 180 response message returned by the receiver user, the 200 OK message, and the ACK message of the sender user can be similarly processed, which greatly reduces the network overhead.

A specific embodiment, as shown in FIG. 4, assumes that both the sender user and the receiver user are mobile phone users, and the user identification information is a mobile phone number.

Step 101: The sender User A submits the Invite message to the core network IMS through the SIP protocol, where the sender address is the User A mobile phone number, and the recipient address is the User B mobile phone number;

Step 102: The core network sends the Invite message to the application server AS to which the User A belongs according to the subscription information of the User A. The Route parameter is added with “mode=mo”, indicating that the User A submits the message. After receiving the Invite message submitted by User A, the AS decodes the Invite message and queries the pre-stored local user information according to the receiver number of the Invite message. If the query fails, the user B is not attributed to the AS. The standard route shown in 1 establishes a session; if the query is successful, it indicates that the user B is also attributed to the AS, that is, User B is a local user, and the short-circuit mode can be used;

Step 103: It is assumed that the receiving user B is also attributed to the local AS, and the user B is the local user. The short-circuit mode is enabled: the AS constructs an Invite message to the user B, where the Route parameter is changed to "mode=mt", indicating that the message is sent. The message to User B forwards the Invite message to the core network;

Step 104: The core network sends the received Invite message to User B.

Step 105: After receiving the Invite message, User B returns a 180 Ringing Zhenling response to the core network.

Step 106: The core network forwards the 180Ringing response to the AS;

Step 107: The AS forwards the received 180 Ringing Zhenling response to the core network.

Step 108: The core network forwards the 180Ringing Zhenling response to User A;

Step 109: After receiving the chat request, User B returns a 200 OK response to the core network.

Step 1010: The core network forwards the 200 OK response to the AS.

Step 1011: After receiving the 200 OK response, the AS forwards the 200 OK response to the core network.

Step 1012: The core network forwards the 200 OK response to User A;

Step 1013: After receiving the 200 OK response, User A establishes a chat session link to the AS, and returns an ACK message to the core network.

Step 1014: The core network forwards the ACK message to the AS.

Step 1015: The AS forwards the received ACK message to the core network.

Step 1016: The core network forwards the ACK message to the User B, and the User B establishes a chat session link to the AS after receiving the ACK.

At this point, the AS establishes a chat session between the sender user and the receiver user, and User A and User B can chat normally.

Through the SIP signaling interaction process, when the sender user and the receiver user belong to an AS, the session connection is established by using the short circuit method, thereby effectively reducing the traffic overhead, improving the network utilization and processing efficiency, and reducing the cost.
