Problems solved by technology

[0004] However, in a mobile network where eMBMS and other services (such as unicast services such as call services) are applied at the same time, there will be a problem of conflict between eMBMS and other services
For example, the subframes occupied by the PMCH (Physical Multicast Channel) of eMBMS will reduce the PRB (Physical Resource Blocks, Physical Resource Blocks) resources that can be used by ordinary LTE services, so that the originally high-priority call services, etc. Unicast services may not be served in time, resulting in call failure or quality degradation, resulting in poor user experience

Embodiment 1

[0122] figure 2 A flowchart showing an eMBMS management method according to an embodiment of the present invention. Such as figure 2 As shown, the method of this embodiment mainly includes:

[0123] S201. The MCE receives load information sent by the base station;

[0124] S202. The MCE manages eMBMS resources according to the received load information.

[0125] Through the method of this embodiment, the MCE can dynamically manage eMBMS resources according to the load information sent by the base station, thereby dynamically coordinating the operation of eMBMS and other services, and solving the problem of conflict between the two in the prior art.

[0126] The base station may actively send the load information to the MCE, or the MCE may first send a query request, and the base station then sends the load information to the MCE in response to the query request.

[0127] The load information may reflect the load level of the base station itself, or the load level of each...

Embodiment approach 1

[0130] In a possible implementation manner, the load information may reflect the load level of the base station, and when the load information shows that the load level of the base station is greater than or equal to the first threshold, the MCE makes the base station exit the single frequency network multicast / Broadcast the MBSFN area, or make at least one of the cells under the base station exit the MBSFN area. This kind of exit is equivalent to releasing base station resources, so that the exited base station or cell no longer participates in eMBMS services, and the released resources are used by other services (such as unicast services with higher priority), so as to realize the utilization of resources occupied by eMBMS. Effective adjustment.

[0131] You can choose to use the base station as the exit unit or the cell as the exit unit according to the needs of the actual situation. For example, if only the load level of a certain cell under the base station exceeds the ...

Embodiment approach 2

[0136] In a possible implementation manner, the MCE may determine the overall load level of the MBSFN area according to the received load information, and when the overall load level of the MBSFN area is greater than or equal to a third threshold, the MCE reduces the eMBMS in the MBSFN area The resource usage of the business.

[0137] This embodiment may further include: when the overall load level of the MBSFN area is less than or equal to the fourth threshold, the MCE increases the resource occupancy of the eMBMS service in the MBSFN area.

[0138] The above embodiment can adjust the occupancy of eMBMS resources based on the overall load level of the MBSFN area, so that when the overall load level is high, some resources occupied by eMBMS services can be released for use by other services, thereby solving the problem of conflict between the two. Adjust the entire MBSFN area to facilitate unified planning and avoid channel discontinuity in the area.

[0139] The overall load...

Abstract

The present invention relates to an enhanced multimedia broadcast multicast service eMBMS management method and device. The eMBMS management method comprises that: a multimedia broadcast multicast service coordination entity MCE receives load information sent by a base station; and the MCE manages eMBMS resources according to the received load information.

Description

technical field [0001] The present invention relates to an eMBMS (Evolved Multimedia Broadcast Multicast Service, enhanced multimedia broadcast multicast service) management method, a multimedia broadcast multicast service coordination entity (MCE) and a base station. In particular, it relates to an eMBMS management method capable of coordinating eMBMS and other services, and an MCE and a base station applying the management method. Background technique [0002] In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) proposed the Multimedia Broadcast Multicast Service (MBMS), in order to provide rich multimedia services in the mobile network, in line with The development trend of mobile data in the future. The eMBMS is supported in the Long Term Evolution (LTE) system to support higher-quality streaming media and timely broadcast services. [0003] figure 1 It shows the logical archite...
