Problems solved by technology
[0007] With the continuous change of services, the multi-cell transmission mode of MBMS is constantly updated; for the above-mentioned messages broadcast on the BCCH channel and information transmitted on the MCCH channel, the requirements on the air interface will be different. At this time, if a unified configuration is adopted method, which cannot meet the performance requirements on different air interfaces; and because MBMS service changes more frequently than MCCH resource configuration, adopting a unified configuration method will bring unnecessary signaling overhead

Embodiment Construction
[0096] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0097] In the embodiment of the present invention, the MBMS-related information in the LTE system can be transmitted on the BCCH and the MCCH respectively, for the MBMS-related information (ie, MCCH configuration information) transmitted on the BCCH and the MBMS-related information transmitted on the MCCH in the prior art (that is, the MBSFN area configuration information) is transmitted to the terminal by the network side equipment. In the embodiment of the present invention, the ne...

The present invention discloses a method, an apparatus and a system for configuring Multimedia Broadcast Multicast Service (MBMS) control information, and the method includes: a network side apparatus broadcasts Multicast Control Channel (MCCH) configuration information to the terminal by Broadcast Control Channel (BCCH), and the MCCH configuration information is received by the terminal; the network side apparatus sends Multicast Broadcast Single Frequency Network (MBSFN) region configuration information to the terminal by the MCCH channel; the MBSFN region configuration information is received by the terminal according to the MCCH configuration information; the network side apparatus sends MBMS service data to the terminal by Multicast Traffic Channel (MTCH); the MBMS service data is received by the terminal according to the MBSFN region configuration information. In the present invention, the network side apparatus broadcasts MCCH configuration information to the terminal by the BCCH channel, and sends MBSFN region configuration information to the terminal by the MCCH channel respectively, thereby the information required to be transmitted in the BCCH channel and MCCH channel is configured in division, the capability requirements of the different air interfaces are satisfied, and the signaling overhead is saved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for configuring MBMS control information. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) system, MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast and multicast services for users in the wireless cell; MBMS can be provided on the frequency layer shared by MBMS services. Among them, the LTE cell that supports MBMS can be an MBMS dedicated cell, or a mixed MBMS and unicast cell; MBMS services can be transmitted in a single cell or in multiple cells; in addition, the multi-cell transmission of MBMS needs to support MBSFN transfer method. [0003] Specifically, MBSFN (Multicast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) refers to synchronous transmission in multiple cells at the same freque...
