Description

Method and device for processing communication terminal discovery and capability detection

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for processing a communication terminal discovery and capability detection.

Background technique

At present, the Rich Communication Suite (RCS), that is, the converged communication, is the three main modules of the original "call", "message" and "contact" in the mobile phone, directly from the carrier level and the mobile phone. Consolidate and turn into new calls, new messages, new contacts. RCS joined the GSMA standard organization in July 2008. The goal is to implement commercialization on the IP Multimedia Subsystem (IMS), and quickly apply new mobile services to provide users with interoperable, converged and rich communications. Experience. The purpose of RCS is not to establish new standards, but to follow existing standards (for example, the 3rd Generation Partnership Project (3GPP), the European Telecommunication Standards Institute (ETSI), The Open Mobile Alliance (OMA) and the Global Systems for Mobile Communications Assocication (GSMA) have developed a core business set that can implement interoperability and IMS-based communication, and develop RCS implementation standards. It also tests the demand satisfaction, service maturity and service interoperability of the verification service, and can quickly realize the commercial application of the IMS service.

The RCS (Release 1-4) specification provides a mechanism for detecting the image and video sharing capabilities of the other party during the call; in the RCS Release 5.1 specification, this mechanism is extended. After the IMS is registered, the RCS performs a converged communication user discovery and capability detection process for the contacts to correctly display the user status in the new contact, and can initiate an appropriate service according to the capabilities of the other party. The specific process is as follows:

Step S1: The RCS user A initiates a fusion communication user discovery and capability detection to the user B, and the user A sends a SIP OPTIONS request to the user B. The contact field carries the IP address of the terminal A and the capability set supported by the A; the Accept-Contact field carries the capability set, and is used by the user A to query which capabilities in the field are supported by the peer;

Step S2: when the OPTIONS request passes through the IMS core network, the capability discovery function entity processes the request;

If User B is already registered with the IMS, the OPTIONS request is forwarded to B. User B returns 200 OK after receiving the request. If it is an RCS user, it carries the supported capability set in the Contact field of the response; otherwise the Contact field does not carry any capability; if User B is not registered in the IMS, but it is an IMS user, the capability discovery function entity returns 480TEMPORARY UNAVAILABLE/408REQUEST TIMEOUT response to user A; if user B is not an IMS user, return 404NOT FOUND response to user A;

Step S3: User A processes the received OPTIONS response;

Step S4: the response is 200 OK and the Contact field carries the capability set of the user B, and the user B can be determined to be the RCS user, and the capability is obtained.

Step S5: the response is 200 OK and the Contact field does not carry any capability, and User B is not an RCS user;

Step S6: the response is 480 or 408, and the user B is an IMS user, but cannot determine whether it is an RCS user, and maintains the original state of the user B in the address book;

Step S7: The response is 404, and User B is not an RCS user.

It can be seen that in the prior art, the RCS user needs to send an OPTIONS request to each contact for the communication communication terminal discovery and capability detection for each contact, and an effective solution has not been proposed for the above problem.

It should be noted that the converged communication service network includes a plurality of network elements, and only the network elements related to the preferred embodiment of the present invention are described in FIG. As shown in FIG. 5, the main sub-terminal and the IMS core network are two parts, and the two parts are explained below.

As the requesting party, the terminal is responsible for initiating the converged communication user discovery and capability detection request for the contact, processing the response and presenting it to the user on the interface; and also acting as the requested party to process the capability detection request, in response Returns the user's ability set.

The IMS core network includes a service access module 52, a new message module 54, and a new contact module 56.

The service access module 52 includes a session control function and a user data management function; wherein the session control function is responsible for functions such as registration, authentication, session control, and signaling routing of the terminal; and the user data management function is used to store the user. The core database of information includes static data and dynamic data; the static data includes the fused communication user identifier, the user's service trigger information, and the like, and the dynamic data includes the user registration status.

6 is a signaling flow diagram of a converged communication user discovery and capability detection according to a preferred embodiment of the present invention. The operation of the module of the above preferred embodiment will be described in detail below with reference to FIG. As shown in FIG. 6 , after the IMS registration is completed, the RCS user A sends a SIP OPTIONS request packet to the capability discovery function to initiate a merged communication user discovery and capability detection process. According to the RCS Release 5.1 specification, the Request URI field of the OPTIONS is the URI of the requested party. In the embodiment of the present invention, end-to-end user discovery and capability detection are not performed, but the capability discovery function is responsible for the capability detection of all contacts, and the recipient of the OPTIONS is changed to the URI of the capability discovery function. The URI can be filled in the domain name of the region, in the format of sip: domain name

In addition, in the SIP protocol, an OPTIONS request corresponds to a response, and a session is uniquely identified by the Call-ID. However, in the present invention, an OPTIONS request may correspond to multiple responses, and each contact corresponds to a response. Therefore, it is necessary to extend the field in the message to identify this special request-response so that the terminal and the server can handle this particular session accordingly. For example, the field Discovery-ID can be extended in the message to uniquely identify the entire discovery process, and the field must be carried in both the request and the response. The following is an example of a message for an OPTIONS request:

After receiving the OPTIONS, the capability discovery function obtains the capability set supported by the user A in the Contact field from the message, so as to be used later, if another user initiates the capability detection, and also obtains the Accept-Contact in the message. Field, which is the set of capabilities that User A wants to ask the contact. Then, the user's contact list is obtained from the network address book function, and the subscription information and registration status of each contact are obtained from the user data management function. After getting the data, do the following for each contact:

For a contact who has registered the IMS and registered the OPTIONS and thus recorded the capability set, the capability discovery module compares the capability set supported by the contact with the capability set that the user A wants to query, and takes the intersection of the two capability sets. , the Contact field placed in the 200 OK is returned to the user A;

For a contact that has been registered by the IMS but does not record the capability set, the capability discovery module forwards the OPTIONS request to the corresponding contact, and the contact receives the OPTIONS and processes it, and returns 200 OK, which also carries its own capability set in the Contact field. The capability discovery module receives the 200 OK and then forwards it to the user A;

For IMS users who are not registered with IMS, the capability discovery module directly returns a 480/408 response;

For non-IMS users whose IMS is not registered, the capability discovery module directly returns a 404 response.

The following is an example of a 200 OK response message requested by OPTIONS:

After receiving the response, User A updates the user category and capability set of the contact, and displays the update on the user interface immediately.

Through the embodiment of the present invention, the RCS terminal sends an OPTIONS request to the capability discovery function of the IMS core network, and the capability discovery function is responsible for the fusion communication user discovery and capability detection of all contacts of the RCS user, and returns the corresponding response to the RCS user. The foregoing technical solutions provided by the embodiments of the present invention can significantly reduce the traffic consumption of the RCS terminal user, improve the efficiency of the discovery and capability detection of the integrated communication user, and improve the user experience of the RCS terminal.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
