Method and device for continuously receiving multimedia broadcast multicast service (MBMS)

Abstract

The invention discloses a method for continuously receiving multimedia broadcast multicast service (MBMS). After user equipment (UE) detects that the receiving MBMS is stopped, the unicast service access with corresponding relationship with the MBMS service is initiated according to the corresponding relationship of the MBMS service and the unicast service, and the MBMS is continuously received through unicast. Meanwhile, the invention also discloses a device continuously receiving MBMS. Through the technical scheme of the invention, the receiving state of users receiving the MBMS can be ensured not to be interrupted, and the service experience of users is improved.

Description

Technical field [0001] The present invention relates to multimedia communication technology, in particular to a method and device for continuous reception of multimedia broadcast and multicast services. Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile terminals, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as video conferencing, TV broadcasting, video on demand, advertising, online education, interactive games, etc. This aspect meets the multi-service needs of mobile users, and at the same time brings new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with ordinary data services, they have the characteristics of large data volume, long duration, and time delay sensitivity. [0003] In order to make effective use of mo...

Problems solved by technology

[0012] However, the current Counting mechanism only counts the reception status of MBMS services by UEs in the RRC connected state, and does not consider the reception status of most UEs in the RRC idle state, which will cause some misjudgment problems

For example, at a certain moment, most UEs are in the idle state and are receiving or are interested in receiving a certain MBMS service, but since only connected state UEs are counted, the statistical result is that the service is not activated or deactivated

In this case, the reception of a large number of idle UEs that are receiving or interested in the MBMS service will be interrupted and cannot continue to receive the MBMS service

In addition, even if only a small number of UEs are interrupted due to service inactivation or deactivation, they will not be able to continue receiving services, thus greatly reducing user experience, which is what operators do not want to see

[0013] In addition, the MBMS technology of the R10 version uses a semi-static MBSFN method to send MBMS services. After the initial configuration of the operator, the size of the sending area will remain unchanged, and the UE can only receive MBMS services in this fixed MBSFN area.

When the UE leaves the MBSFN area due to movement or other reasons, it will not be able to continue to receive services, resulting in service interruption

In addition, MBMS services may also be preempted by services with higher priority, thus stopping service transmission; or the UE leaves the effective area of ​​the MBMS service, which will also cause the suspension of MBMS services

All of the above situations will cause the UE to be unable to continue receiving MBMS services, thereby reducing user experience
