Problems solved by technology

[0015] As mentioned above, when MRFC selects an MRFP, it only considers whether the MRFP is available and whether the MRFP has media resources that can provide the requested service. This method of providing business services only from the perspective of business success or failure has The following disadvantages: may cause unnecessary waste of network resources, and may also reduce business service quality
For example: assume that a user currently in area A initiates a service request. According to the above process, after the MRFC receives the service request, it detects that the MRFPs that are currently available and have media resources corresponding to the requested service include: MRFP1 located in area A and MRFP2 is located in area B. At this time, MRFP will choose one of MRFP1 and MRFP2 to complete this service. If MRFP2 is selected, compared with MRFP1, when performing services, MRFP2 and the user are not in the same area. , then when interacting with business-related signaling and media streams, it will take up more bearer network resources, reduce the utilization of network resources, increase processing delays, and reduce business service quality

Embodiment Construction

[0038] The core idea of ​​the present invention is: MRFC acquires and saves the corresponding relationship between MRFP and special service attribute information. When MRFC receives the service request sent by S-CSCF, if it detects that the service request carries special service attribute information, then Among the available MRFPs that can provide media resources corresponding to the requested service, an MRFP corresponding to the special service attribute is selected to complete the current service.

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] image 3 It is a flow chart of multimedia services performed by the IMS provided by the present invention, such as image 3 As shown, the specific steps are as follows:

[0041] Step 301: MRFC obtains and saves the corresponding relationship between MRFP and special service attribute information.

[0042] The special service...

Abstract

This invention discloses a method for carrying out multimedia service, which gets and stores the corresponding relation of MRFP and particular service attribute information by MRFC, then it looks for the MRFP corresponding to the particular service attribute carried by a service request based on the corresponding relation in the MPFP after the MRFC receives the service request sent by S-CSCF and tests the particular service request information carried by the service request and sends the request to the MRFP, which provides service after receiving the service request.

Description

technical field [0001] The invention relates to the technical field of service provision in the IP multimedia subsystem, in particular to a method for performing multimedia services in the IP multimedia subsystem. Background technique [0002] IP Multimedia Subsystem (IMS) is a subsystem in the Wideband Code Division Multiple Access (WCDMA) network added by the Third Generation Partnership Organization (3GPP) in the R5 stage, which can provide audio, video, text, chat, etc. The relevant network entities include: Call Session Control Function (CSCF), Media Gateway Control Function (MGCF), Multimedia Resource Function (MRF) and so on. In the actual application and development process, IMS has tended to become a subsystem that has nothing to do with access. Various types of terminals can establish peer-to-peer IP communication through IMS and obtain required services. In addition to supporting session management, IMS can also provide functions necessary to complete services su...
