Problems solved by technology

[0018] It can be seen that for a specific MBMS service in the MBSFN area, it will be transmitted in the entire MBSFN area; in practical applications, it is sometimes not necessary for a certain MBMS service to be transmitted in the entire MBSFN area, for example , there may be no users receiving the MBMS service in some / some cells in the MBSFN area, or when the number of users receiving the MBMS service is lower than the threshold value, if the MBMS service continues to be sent in this / some cells , which undoubtedly reduces the utilization of wireless resources and causes a waste of transmit power

[0098] In the first embodiment, it is assumed that UEs receiving MBMS services under each eNB in ​​the MBSFN area report the names of the MBMS services they are receiving to their respective eNBs through uplink feedback; each eNB aligns the feedback information it obtains to a certain Take an eNB such as eNB X as an example, as shown in Table 1:

[0099] MBMS business name

Number of UEs being received (unit: number)

MBMS service A

[0100] Table 1

[0101] Each eNB uses the integrated information to schedule MBMS services, and determines to turn on / off certain MBMS services. The specific implementation in the first embodiment is as follows:

[0102] eNB X knows that the number of UEs that are receiving MBMS service B in the cell to which it belongs is 0, therefore, eNB X decides to turn off the transmission of MBMS service B in the cell to which it belongs. From the perspective of wireless resources, Picture 9 This is a schem...

[0107] The eNB reports the integrated information to the MCE; the information reported to the MCE may be the number of UEs each MBMS service is receiving, or the eNB's decision on whether to send each MBMS service. In the second embodiment, the eNB reports to the MCE its decision on whether to send each MBMS service; the details are as follows:

[0108] eNB Y learns that the number of UEs receiving MBMS service C in its cell is 0, therefore, eNB Y initially decides to turn off the tr...

[0111] In the third embodiment, it is assumed that each eNB in ​​the MBSFN area decides to turn on or off the transmission of the MBMS service of the cell to which it belongs. Each eNB will turn on or turn off the transmission of a certain / certain MBMS service. In the third embodiment, a certain eNB such as eNB Z will turn off the MBMS service B as an example.

[0112] eNB Z decides and executes to close the transmission of MBMS service B in the cell to which it belongs; from the perspective of radio resources, the multicast subframe configuration and application of eNB Z are as follows Picture 9 Shown.

[0113] In the fourth embodiment, it is assumed that the MCE in the MBSFN area determines whether to turn on or off the transmission of the MBMS service of the cell to which each eNB belongs; each eNB executes to turn on or off the transmission of a certain / certain MBMS service according to the decision of the MCE. Taking a certain eNB such as eNB M to turn off MBMS service B as a...

Abstract

The invention discloses a method and system for realizing MBMS (Multimedia Broadcast Multicast Service) service scheduling. The method comprises the following steps of: setting a scheduling condition in a scheduling network element; and scheduling the multimedia broadcast multicast service (MBMS) service by taking a cell in a multicast broadcast single frequency network (MBSFN) region as an object according to the scheduling condition. According to the method, the MBMS service scheduling by taking the cell in the MBSFN region as an object is realized, and transmission of the MBMS service in the cell is prevented from being closed in a cell where no user receives the MBMS service, or when the number of users receiving the MBMS service in the cell is lower than a threshold, so that the utilization ratio of wireless resources is increased, and waste of transmission power is avoided.

Description

Technical field [0001] The present invention relates to Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service) technology, in particular to a method and system for implementing MBMS service scheduling. Background technique [0002] With the rapid development of the Internet and the popularity of large-screen multifunctional mobile phones, 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, video advertising, online education, interactive games, etc. . These mobile data multimedia services and high-bandwidth multimedia services not only meet the rising business needs of mobile users, but also bring new business growth points for mobile operators. [0003] Mobile data multimedia services and various high-bandwidth multimedia services require multiple users to receive the same data at the same time. Compared with general data service...
