Problems solved by technology

[0010] The above solution is suitable for the existing IP network, using protocols such as HTTP to obtain the electronic program list. For terminals supporting SIP, the above solution is still applicable; however, the service discovery mechanism of the above solution is not flexible enough, which is reflected in the following Several aspects: 1. The user needs to initiate a request to the service server, and the service server will send the electronic program list to the user; 2. The user is required to obtain the address of the service server in advance. For example, the address of the service server is published on the website, and the user manually configured on the terminal

Embodiment Construction

[0038] see figure 2 In the first embodiment of the present invention, the electronic program guide acquisition system includes a terminal, a proxy CSCF, a serving CSCF, an HSS, an AS, and a metadata provider, wherein the terminal receives the program guide issued by the AS, or actively requests the program list according to the address issued by the AS The program list; the proxy CSCF forwards the request and response messages between the terminal and the serving CSCF; the serving CSCF downloads the filtering criteria from the HSS, the filtering criteria include trigger rules, and the serving CSCF triggers the service request message to the AS according to the triggering rules, and the message Routing; HSS stores user subscription information; AS generates and provides electronic program guide to terminal; metadata provider provides basic metadata for generating electronic program guide to AS, and the metadata is used for content, access method, purchase data, etc. be describ...

Abstract

The method comprises: a1) the terminal is registered and authenticated at IMS network; a2) the serving CSCF initiates a third party authentication to AS, and both parties complete the third party authentication through interaction; a3) the AS decides if an electronic program-menu needs to be immediately sent to the terminal; if yes, then the AS actively sends the electronic program-menu to the terminal; if not, the AS sends a describing message about the acquirable electronic program-menu, which comprises the indication to the terminal, namely the operations required to be executed when desiring the electronic program-men; according to the instruction, the terminal gets the electronic program-menu. The invention also reveals a system thereof.

Description

technical field [0001] The invention relates to a system and method for acquiring an electronic program list. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is one of the multimedia communication system framework protocols formulated by IETF (The Internet Engineering Task Force, Internet Engineering Task Force), and is an application layer protocol used to establish, change or end multimedia sessions. RTP (Realtime Transport Protocol, Real-time Transport Protocol) / RTCP (Real-time Transport Control Protocol, Real-time Transport Control Protocol), SDP (Session Description Protocol, Session Description Protocol), RTSP (Real Time Stream Protocol, real-time streaming protocol), DNS ( Domain Name System and Domain Name Service protocol, domain name system (service) protocol) and other protocols cooperate to complete the session establishment and media negotiation in IMS (IP Multimedia Subsystem, IP Multimedia Subsystem); once the sessi...
