Method, system, corresponding device and communication terminal for providing MBMS service

Abstract

The invention discloses a method, a system, a safety device, a service control device and a communication terminal for providing MBMS service. The method comprises the following steps that: a service control module in an IMS system carries out service authentication according to a service authentication request to acquire an authentication passing result; the service control module sends the authentication passing result to a safety module; and the safety module acquires the authentication passing result and then sends a service decipher of MBMS service to users. The controlling capacity of anIMS and the carrying capacity of an MBMS are multiplexed on the basis of the IMS system and an MBMS system to achieve IPTV service so as to realize the uniform authentication and uniform network management. The binding of the IPTV service with other services can be realized by utilizing the IMS, and personalized services can be provided to the users.

Description

Technical field [0001] The invention involves the field of communication, especially the methods, systems, corresponding devices and communication terminals that provide MBMS services. Background technique [0002] Multimedia Broadcast (MBMS) is proposed by the Global Standardized Organization 3GPP (MBMS). MBMS technology refersPoints to send data to multiple points of data. [0003] The timing process of the IP TV (IPTV) business is figure 1 The process is as follows: [0004] 1) User (UE) to obtain electronic program menu (EPG) to the business selection function module (SSF) in the system. [0005] 2) UE registered with the broadcast multi-broadcast business center (BM-SC) through HTTP POST. [0006] 3) BM-SC sends a registration response to users. [0007] 4) If the registration is successful, the BM-SC will send the MSK encrypted MSK to the user through MUK after the registration is successful.The picture does not show the process of obtaining MUK through the GBA (General Boo...

AI Technical Summary

Problems solved by technology

[0009] However, the technology described above provides IPTV based on MBMS, and cannot be controlled by the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) network, so that the rich service capabilities of IMS cannot be utilized.
