Problems solved by technology

[0005]In this method, when the UE needs to select a streaming media service, the address of the SISF must be fixed in the UE and actively send a request to the SISF to obtain the service selection information, so this method cannot automatically obtain service selection information, which brings poor user experience

Embodiment Construction

[0027] In order to make the above objects, technical solutions and advantages clearer, the present invention will be described in detail below in conjunction with specific embodiments.

[0028] The method and system for discovering streaming media services provided by the embodiments of the present invention are all based on the IMS technology to realize the automatic discovery of streaming media services.

[0029] The main method provided by the embodiment of the present invention is as follows: the IMS network side generates service selection information and service discovery information, and sends the service discovery information to the UE according to the information about the UE's access to the IMS network; the UE obtains the service discovery information according to the service discovery information. Service selection information generated by the IMS network side.

[0030] The service discovery information may be address information of a service selection unit, or mult...

Abstract

The invention provides a method and a system for finding out streaming media services. The method is that: the network side of an IP multimedia sub-system (IMS) generates service choosing information and service finding information and sends the service finding information to a UE according to the information for the UE to be connected into the IMS network; the UE obtains the service choosing information generated by the IMS network side according to the service finding information. Based on the IMS technology, a service finding unit can automatically send the service finding information to the UE according to the information for the UE to be connected into the IMS network; the UE obtains the service choosing information according to the service finding information, thus the user can simply and conveniently complete the obtaining of the service choosing information with no need of complicated operations and has better experience.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and system for discovering streaming media services. Background technique [0002] IP Multimedia Subsystem (IMS) is a subsystem superimposed on the existing packet domain in the Wideband Code Division Multiple Access (WCDMA) network added in the 3rd Generation Partnership Project Release 5 (3GPP R5) phase. Its upper layer controls the bearer channel of signaling and media transmission, introduces Session Initiation Protocol (SIP) as a service control protocol, and provides rich multimedia services by separating service control from bearer. SIP is one of the multimedia communication system framework protocols formulated by the Internet Engineering Task Force (IETF). It is an application layer protocol used to establish, change or end multimedia sessions. Session Description Protocol (SDP), Real Time Streaming Protocol (RTSP) and other protocols work together to compl...
