Problems solved by technology

Assuming that in an MBSFN area, when a connected UE receiving MBMS services moves to the cell boundary, the source eNB determines that the target cells for handover may be Cell 2 and Cell 3 according to the measurement report of the UE. Assuming that Cell 2 supports MBMS services, the cell 3 Not supported, the source eNB may handover the UE to cell 3 according to the unicast mobility management algorithm, which will not ensure the continuity of the MBMS service of the UE in the connected state
In order for the source eNB to make a handover decision that can ensure the continuity of the MBMS service, the eNB needs to know the MBMS service reception status of the UE before the handover, and there is no related solution at present

Embodiment Construction

[0030] In the embodiment of the present invention, the UE reports the state of receiving the MBMS service to the network side through the measurement report, thereby realizing the reporting of the MBMS service state. Based on this, when the network side knows that the UE is receiving the MBMS service, during the handover process, the adjacent cell related to the MBMS service received by the UE is taken as the target cell for handover, and the UE is handed over to the target cell, thereby improving the MBMS service transmission. continuity.

[0031] see figure 1 , the main method flow for reporting the MBMS service status in this embodiment is as follows:

[0032] Step 101: The UE is triggered by a measurement report trigger mechanism, and determines that a measurement report needs to be reported. The measurement reporting trigger mechanism includes event-triggered reporting, periodic reporting, or event-triggered periodic reporting.

[0033] Step 102: When the UE is in the ...

Abstract

The invention discloses a method for reporting a multimedia broadcast multicast service (MBMS) status, which is used for reporting the MBMS status. The method comprises the following steps that: user equipment (UE) is triggered by a measurement report triggering mechanism, and determines that a measurement report is needed to be reported; when the UE is in the status of receiving MBMS, the UE generates the measurement report with first indication information indicating that the UE is in the status of receiving the MBMS; and the UE transmits the generated measurement report to a network side. The invention also discloses a device for implementing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for reporting MBMS service status. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast and multicast services for users in wireless cells. In order to solve problems such as blind area coverage, enhance the reliability of reception, and improve coverage, the industry has proposed MBMS multi-cell transmission technology, such as MBSFN (Multicast Single Frequency Network) technology. The MBSFN technology refers to synchronous transmission in multiple cells at the same frequency at the same time, and supports the combination of MBMS transmission in multiple cells. [0003] The measurement mechanism is one of the important mechanisms in the communication system. A user equipment (UE) can perform intra-frequency measurement, inter-frequency measurement and inter-technology measurement (that is, cross-syst...
