Problems solved by technology
This means that a new wireless access network supporting MBMS must be built or a large number of Node Bs in the existing network must be upgraded, which is not conducive to the maintenance and smooth transition of the existing network
[0007] Assuming that the cell does not support the transmission of MCCH control messages, the cell cannot implement the PTM transmission method. Even if the cell only supports the PTP transmission method, the UE in the idle (IDLE) mode and the access network paging (URA_PCH) state needs to pass paging. Establishing a point-to-point (PTP) radio bearer (Radio Bearer, RB), which not only increases the complexity of implementation, but also causes a waste of resources

Embodiment Construction
[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.
[0020] The invention mainly relates to a multimedia broadcast multicast service transmission method used in a Wideband Code Division Multiple Access (WCDMA) mobile communication system.
[0021] refer to figure 2 , illustrating a multimedia broadcast multicast service transmission method according to an embodiment of the present invention. Such as figure 2 As shown, the multimedia broadcast multicast service transmission method includes the following steps: S202, the radio network controller determines whether to add the point-to-multipoint indicator channel configuration information to the multimedia broadcast multicast service according to whether the point-to-multipoint indicator channel is successfully established In the control message, and send the processed multimedia broadcast multicast service control message to at le...

The invention discloses a multimedia broadcast / multicast service transmission method which comprises the following steps: S202, a wireless network controller determines whether point-to-multipoint indication channel configuration information is added into multimedia broadcast / multicast service control information according to whether a point-to-multipoint indication channel is established successfully or not, wherein, the point-to-multipoint indication channel configuration information is optional in the multi-media broadcast / multicast service control information; S204, after receiving the multimedia broadcast / multicast service control information from the wireless network controller, a user device checks whether the multi-media broadcast / multicast service control information contains the point-to-multipoint indication channel configuration information or not and carries out corresponding processing. The method of the invention can ensure that the user device can enjoy continuous MBMS service when moving in communities.
Description
technical field [0001] The present invention relates to the communication field, and more specifically relates to a multimedia broadcast multicast service transmission method. Background technique [0002] Multimedia Broadcast / Multicast Service (MBMS for short) is a technology for sharing network resources and transmitting data from one data source to multiple targets. In order to effectively utilize mobile network resources, 3GPP proposed the MBMS service in R6, that is, to provide a point-to-multipoint service in which one data source sends data to multiple users in the mobile network, so as to realize network resource sharing and improve the utilization of network resources efficiency (especially the utilization of valuable air interface resources). MBMS can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services, and provide a variety of rich video, audio, and multimedia services, w...
