Description

A kind of MBSFN operation domain dynamic creation method and MCE
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of MBSFN(Multimedia Broadcast multicast service Single Frequency Network, the multimedia broadcast multi-broadcasting business Single Frequency Network) operation domain dynamic creation method and MCE(MBMS Coordinate Entity, the multimedia broadcast multi-broadcasting business coordination entity).
Background technology
3GPP(The3rd Generation Partnership Project, third generation partner program) defined MBMS(Multimedia Broadcast Multicast Service in, multimedia broadcast multi-broadcasting business) network configuration and business need, support point-to-multipoint service, in order to realize the transmission of identical data from a data source to a plurality of targets.
E-MBMS(Evolved Multimedia Broadcast Multicast Service, evolutionary multimedia broadcast multi-broadcasting) introduced SFN(Single Frequency Network, Single Frequency Network in Access Network) transmission means.SFN is the radio-transmitting station that is in synchronous regime by a plurality of different locations, at one time, with the same signal of same frequency emission, with the reliable covering of realization to certain service area, thereby can transmit by SFN the MBMS business of higher rate.At MBSFN(Multimedia Broadcast multicast service Single Frequency Network, the multimedia broadcast multi-broadcasting business Single Frequency Network) in service-domain, neighbor cell can not cause presence of intercell interference, can obtain descending macro diversity on the contrary.
What relate to due to the MBSFN transmission means is the synchronous transmission of many minizones, therefore need the zone of MBSFN transmission is defined: the MBSFN service-domain, refer to have the ability to carry out the zone of MBSFN transmission, all the evolution base station eNodeB this zone in can be by synchronous and carry out MBSFN and transmit; The MBSFN operation domain refers to realize by coordination the residential quarter that MBSFN transmits.Obviously, the scope of MBSFN operation domain can not exceed the scope of MBSFN service-domain.
3GPP is at LTE(Long Term Evolution, Long Term Evolution) for sending, the E-MBMS business defined two kinds of working methods in system:
1) static MBSFN mode
No matter in the residential quarter of MBSFN service-domain, whether UE subscribing MBMS business is arranged, all can open transmission channel and carry out the MBMS synchronous transmission.This mode is the basic mode of broadcasting service, is specially adapted to the special carrier scene, and namely in the BSFN service-domain, MBMS special carrier service data transmission is used in all residential quarters; Also can be applicable to the mixed carrier scene based on demand in the network operation process, namely have the residential quarter to use service data transmission on the mixed carrier of MBMS transmission/clean culture Unicast data in the MBSFN service-domain, the clean culture of residential quarter and MBMS transmission can be coordinated to walk abreast.
Although this mode can make the residential quarter of UE subscribing MBMS business obtain great descending macro diversity, easily causes the waste of interface-free resources and power resource.
2) dynamic MBSFN mode
For the special carrier scene, the residential quarter does not provide up link, there is no the counter mechanism based on the echo message of UE statistics, therefore do not support unicast transmission, and for the mixed carrier scene, the residential quarter provides up link, have the counter mechanism based on the UE echo message, therefore support unicast transmission.
For the mixed carrier scene, further strengthen on the basis of static MBSFN mode, the generation of MBSFN operation domain is dynamically controlled, be specially the centralized MBSFN operation domain management based on counting, echo message based on the UE statistics, carry out following mark with the residential quarter in the MBSFN service-domain:
For the residential quarter that the UE subscribing MBMS is arranged, the residential quarter is labeled as 1 class residential quarter, the base station is opened the MBMS transmission channel according to mark to these residential quarters, carries out the transmission of MBMS;
For the residential quarter that there is no the UE subscribing MBMS, the residential quarter is labeled as 0 class residential quarter, the base station is closed the MBMS transmission channel according to mark to these residential quarters, carries out unicast service and sends;
As seen, whether MBSFN operation domain management only has the UE subscribing MBMS relevant with this residential quarter, namely the MBMS transmission channel is just opened in the residential quarter of the UE that has the subscribing MBMS business, does not exist the residential quarter of the UE of subscribing MBMS business just to close the MBMS transmission channel.
although aforesaid way is conducive to promote the efficient of eating dishes without rice or wine, and saving power resource, improved the utilance of Radio Resource, but owing to only having considered whether subscribing MBMS business information of UE, can not satisfy the demand of the interior descending macro diversity of MBSFN operation domain in MBSFN operation domain dynamic management demand, can not avoid occurring " SFN hole " and " SFN isolated island ", although the SFN hole refers to its adjacent cell of certain residential quarter and all opens the MBMS transmission channel, but because it is positioned at MBSFN service-domain central area, the transmission of unicast service can have a strong impact on the MBMS transmission of peripheral cell, although the SFN isolated island refers to certain residential quarter and opens the MBMS emission, but it is less that its peripheral cell is opened the residential quarter of MBMS emission, can not obtain fine descending macro diversity, this will affect the receptivity of MBMS greatly.
