Embodiment 1

[0031] In the energy-saving scenario, the system can independently decide to shut down certain cells with enhanced coverage. In this case, the system needs to broadcast indication information that the cell is about to be shut down through a radio resource control (Radio Resource Control, RRC) interface before shutting down the cell. UEs that are in the RRC_IDLE state and are currently receiving enhanced Multimedia Broadcast Multicast Service (eMBMS) in the form of Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) need to pay attention to the above broadcast information. After the above-mentioned UE receives the indication information that the cell is about to be shut down, it needs to determine in time the best target reselection cell except the current cell; and then judge whether the target reselection cell can support the continuity of its own eMBMS service, if not If it is not supported, other procedures need to be used to require the target reselect...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that in Step 1, the broadcasting method is: placing the indication information in System Information Block Type 13 (SystemInformationBlockType13, SIB13), and broadcasting to UE through BCCH (Broadcast Control Channel), The broadcast process is as follows image 3 shown. The characteristic of this broadcast method is: within the service area of ​​the cell, only UEs that care about the eMBMS service and have the ability to receive the eMBMS service in the MBSFN mode will receive it. This method also does not need to carry the ECGI of the cell.

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is that in step 1, the broadcasting method is: a new message type SwitchoffOngoingIndication Message is added in the multicast control channel message class (Multicast Control Channel Message Class, MCCH-Message Class), Broadcast to UE through MCCH (Multicast Control Channel), the broadcast process is as follows Figure 4 shown. The characteristics of this broadcast method are: broadcast in the MBSFN area where the cell is located, and all UEs in the MBSFN area that care about eMBMS services and are capable of receiving eMBMS services in MBSFN mode can receive it, so in this case, it is necessary to carry the ECGI of the cell . In addition, if a cell belongs to multiple MBSFN areas at the same time, the indication information needs to be broadcast on the MCCHs corresponding to the multiple MBSFN areas at the same time.

Abstract

The invention discloses a method for ensuring eMBMS (Multimedia Broadcast Multicast Service) service continuity in an energy-saving scenario. The method comprises the steps as follows: step 1, in the energy-saving scenario, when an energy-saving community meets the triggering condition of energy saving, the energy-saving community broadcasts indication information that the energy-saving community be closed soon to UE (User Experience) in a current service scope through an RRC interface; step 2, in the energy-saving community, UE in an RRC (Radio Resource Control)_IDLE state and in an MBSFN mode currently to receive eMBMS service pays attention to the indication information; and steps 3, after obtaining the indication information that the energy-saving community will be closed, the UE selects a target reselection community at the right time according to the content of the indication information, then, the UE obtaining the indication information judges whether the target reselection community supports the eMBMS service continuity; and if not, the UE informs the target reselection community to try to deploy the eMBMS service so as to meet the requirements for the eMBMS service continuity. The method of the invention can better ensure the eMBMS service continuity of the UE in an RRC_IDLE state in an energy-saving scenario through systematically.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for ensuring continuity of eMBMS services in an energy-saving scene. Background technique [0002] The 3rd Generation Partnership Project (3GPP) introduced the Multimedia Broadcast / Multicast Service (MBMS) feature in the R6 version to realize the simultaneous transmission of data from a data source to multiple users within a specific range. A point-to-multipoint service that enables network resources to be shared, thereby providing multimedia services to a large number of users with the same needs at the same time with less resources. Under the LTE network architecture, some changes have taken place in the implementation framework and method of the MBMS service at the bearer level. We call it eMBMS to distinguish it from the previous MBMS bearer implementation. [0003] A relatively important change in eMBMS is the introduction of the transmission concept o...
