Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0049] see figure 1 As shown, the implementation method of the first multimedia broadcast multicast service provided by the present invention mainly includes the following steps:

[0050] Step 101: the network side sends the MBMS service configuration information to the UE through the broadcast control channel BCCH;

[0051] Step 102: The UE receives the MBMS service according to the MBMS service configuration information received from the BCCH.

[0052] Wherein, the MBMS service configuration information includes MBMS common point-to-multipoint radio bearer configuration information (MBMS commonp-t-m RB configuration information), MBMS current cell point-to-multipoint radio bearer configuration information (MBMS current cell p-t-m RB configuration inf...

Abstract

The present invention provides a method and system for implementing multimedia broadcast multicast service, capable of reducing implementation complexity of MBMS. The method includes that: network side transmit the MBMS service configuration information to UE through broadcast control channel MCCH, UE receives MBMS service according to the received MBMS service configuration information from MCCH.In addition, the invention also provides another two methods and system for implementing multimedia broadcast multicast service, which implements MBMS service on the basis of supporting multi-frequency point characteristics.The method includes that: MCCH is configured on each frequency point of multi-frequency point cell, network side transmit the MBMS control information to UE through MCCH, UE receives MBMS service according to the received MBMS control information from MCCH.Or, MCCH is configured on main frequency point of multi-frequency point cell, network sides transmit the MBMS control information to UE through MCCH of main frequency point, UE receives MBMS service according to the received MBMS control information from MCCH of main frequency point.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for realizing Multimedia Broadcast Multicast Service (MBMS). Background technique [0002] With the rapid development of mobile communication technology, the widespread use of mobile communication networks and the rapid growth of the number of mobile communication users, the realization of broadcast and multicast technology in mobile communication networks has become one of the hot spots in the development of mobile communication systems. MBMS refers to a point-to-multipoint (PTM) service that sends data from one data source to multiple users. Broadcasting, so as to realize the sharing of network resources, realize the service to as many multimedia users as possible with the same needs with as few resources as possible. [0003] Three new logical channels and one new physical channel have been added in MBMS. The new logical channels are: MBMS point-to-multi...
