The embodiment can ensure the reliability of MCCH synchronous transmission among all base station equipment in the entire MBSFN area and effectively improve the coverage efficiency of the MBMS (Multimedia Broadcast and Multicast Service) control message on the system periphery.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to a kind of multicast control channel message synchronization sending method, device and system.
Background technology
MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast-multicast service) is 3GPP (3rd Generation Partnership Project, third generation partner program) the multimedia broadcasting and multicast function that defines among the R6 is used to the user in the wireless area that multimedia broadcasting and multicast services are provided.At LTE (Long Term Evolution, Long Term Evolution) in the system, MBMS dedicated frequency layer and can both provide MBMS with the professional frequency layer of sharing of non-MBMS supports that the LTE sub-district of MBMS can be the MBMS dedicated cell, also can be MBMS/ clean culture mixed cell.
Wherein, MBMS dedicated frequency layer is meant the frequency layer that is specifically designed to the MBMS transmission, and when a sub-district was configured to MBMS dedicated frequency layer, this sub-district was the MBMS dedicated cell; Being configured to when a sub-district is not when being specifically designed to the frequency layer of MBMS transmission, this sub-district is a MBMS/ clean culture mixed cell, clean culture and MBMS business in the MBMS/ clean culture mixed cell are worked in coordination with transmission, and some is used for the professional transmission of MBMS constantly, and other the moment is used for the unicast service transmission.MBMS can carry out single cell transmission, also can carry out many cell transmission, single cell transmission of MBMS is meant that MBMS only transmits in the coverage of a designated cell, do not support the combination from the MBMS transmission of many sub-districts, and many cell transmission of MBMS need be supported the MBSFN transmission means.
MBSFN (Multicast Broadcast Single Frequency Network, multicast single-frequency network) is meant the mode of carrying out synchronous transmission at one time with same frequency in a plurality of sub-districts, can save frequency resource, improves the availability of frequency spectrum.MBSFN requires a plurality of sub-districts to send identical content simultaneously, UE (User Equipment, subscriber equipment) receiver can be considered as a plurality of MBSFN sub-district a big sub-district, not only can not be subjected to the presence of intercell interference of neighbor cell transmission, but also will benefit from stack from the signal of a plurality of MBSFN sub-district.MBMS dedicated cell and MBMS/ clean culture mixed cell can adopt the MBSFN transmission means.In addition, utilize advanced UE receiver technology can also solve the time difference problem of multipath transmisstion, disturb thereby eliminate in the sub-district; Multiple sectors at same keeps pouring in the defeated diversity that brings can also solve problems such as blind area covering, strengthens the reliability that receives, and improves coverage rate.
The technical characterstic of the many cell transmission of MBMS comprises: the synchronous transmission of MBMS in the MBSFN zone; Support the merging of many cell MBMS transmission; MTCH (MBMS point-to-multipoint TrafficChannel, multimedia broadcast-multicast service is put the multi-point flux channel) and MCCH (MBMSpoint-to-multipoint Control Channel, multimedia broadcast-multicast service is put the multiple spot control channel) be mapped in and be used for PTM (Point to Multi-point, point is to multiple spot) on the MCH (MulticastChannel, multicast channel) of transmission; The MBSFN retaining zone can be passed through O﹠amp; M (Operation andMaintenance, operation and maintenance) system etc. carries out semi-static configuration.
For many cell transmission of MBMS, a carrier frequency can be supported a plurality of MCH.The distribution of the physical resource of MCH can be by specifying the pattern of a subframe to finish for MCH, and relevant sub-frame in time need not be adjacent, and above-mentioned pattern is called, i.e. MSAP (MCH Sub-frame Allocation Pattern, MCH sub-frame allocation pattern).Particularly, by the MSAP that MCCH notifies each to carry the MCH of MTCH, be mapped on the MCH with a plurality of MTCH, the order of transmission of each MTCH is also notified by MCCH.A MCH only comprises the data that belong to a MBSFN zone, but each MCH can shine upon a plurality of MBMS business.
In the LTE system, except guaranteeing the MBMS business datum, needs in the MBSFN zone, carry out synchronized transmission, and MCCH also is mapped to MCH, therefore needs also to guarantee that MCCH carries out synchronized transmission in the MBSFN zone.
In the existing systems design, can adopt MCE (Multi-Cell/Multicast CoordinationEntity, many sub-districts/multicast coordination entity) concentrate the method for tissue and transmission MCCH message to guarantee the synchronized transmission of MCCH in the MBSFN zone, concrete steps comprise: MCE receives after the MBMS session begins message, begin to organize the MCCH configuration messages, comprise MBSFN sign, the physical configuration information of MCCH, the configuration information of MTCH in this MCCH configuration messages, and the entry-into-force time of configuration point etc.; MCE transmits message by the M2 interface and gives eNB (Evolved Node B, evolved Node B); ENB is according to the physical resource of message appointment, and at the time point of appointment, order sends MCCH message
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
When adopting MCE to concentrate tissue and sending MCCH message and guarantee the synchronized transmission of MCCH in the MBSFN zone, the inconsistent situation of message status that eNB receives may appear, and reliability is relatively poor.For example: if eNB does not have up-to-date MCCH information, the MCCH information before will sending, and send between the eNB of up-to-date MCCH information and can't keep can bringing very big interference on the contrary synchronously.
