Problems solved by technology

[0008] During the research and practice of the prior art, it is found that there are the following problems: in the prior art solution, if a cell belongs to multiple MBSFN areas, that is, multiple MBSFN areas have overlapping areas, then there are multiple MBSFN areas in this cell MCCH, each MCCH channel corresponds to an MBSFN area; UE enters the MBSFN cell, reads BCCH, Electronic Service Guide (ESG, Electronic Service Guide) and MCCH, and finds that the required MBMS service has not started; or the UE does not receive in the MBSFN cell For MBMS services, after a period of time (maybe one or more MCCH modification periods, during which time, the UE does not read MCCH information), the UE wants to receive MBMS services, and the UE judges the desired reception according to the ESG and the stored MCCH information. The MBMS service has not started; in the above two cases, the UE listens to the MCCH notification information
If you do not know the corresponding relationship between MBMS services and MCCHs, the UE monitors all MCCH notification messages, but the UE cannot judge the specific MBMS services that have changed based on the above notification messages, so the UE needs to continue to read all the changed MCCH information, which will increase Power consumption of UEs capable of receiving MBMS in overlapping MBSFN areas
If the desired MBMS service has already started, the UE will not be able to receive the required MCCH notification message, resulting in the UE being unable to receive the required MBMS service

Embodiment 1

[0066] The application scenario of this example is that there are more than two MCCHs in the MBSFN cell, the UE is not currently receiving any MBMS service, there is an MBMS service that the UE wants to receive in the MBSFN cell, and the UE knows the correspondence between the MBMS service that the UE wants to receive and the MCCH; figure 1 As shown, the method for monitoring notification information of the multimedia broadcast multicast service control channel in this example includes the following steps:

[0067] 101. The UE receives messages related to MBMS services;

[0068]The message related to the MBMS service can be one or more of the following messages: ESG, MCCH information, short message, multimedia message, system message, RRC message; the receiving MBMS service related message can be received periodically, or according to The signaling indicates real-time reception; the above information may include, but is not limited to, one or more of the following: MBMS servic...

Embodiment 2

[0080] The application scenario of this example is that there are more than two MCCHs in the cell, the UE does not currently receive the MBMS service, there is an MBMS service that the UE wants to receive in the cell, and the UE does not know the corresponding relationship between the MBMS service that the UE wants to receive and the MCCH; figure 2 As shown, the method for monitoring notification information of the multimedia broadcast multicast service control channel in this example includes the following steps:

[0081] 201. The UE receives messages related to MBMS services;

[0082] This step is the same as the aforementioned step 101.

[0083] 202. The UE judges whether the required MBMS service is started, if yes, execute step 203, if not, execute step 204;

[0084] 203. The UE reads all MCCH information in the cell;

[0085] Since the UE has not obtained the corresponding relationship between the desired MBMS service and the MCCH, it needs to read all the MCCH inform...

Embodiment 3

[0093] The application scenario of this example is that there are more than two MCCHs in the cell, the UE is receiving the MBMS service, there are other MBMS services that the UE wants to receive in the cell, and the UE knows the correspondence between the MBMS service and the MCCH; image 3 As shown, the method for monitoring notification information of the multimedia broadcast multicast service control channel in this example includes the following steps:

[0094] 301. The UE receives messages related to MBMS services;

[0095] This step is the same as the aforementioned step 101.

[0096] 302. The UE obtains the corresponding relationship between the MBMS service and the MCCH;

[0097] This step is the same as the aforementioned step 102 .

[0098] 303. The UE also wants to access other MBMS services, and further judges whether the required MBMS service is started. If it is started, perform step 304. If not, perform step 307;

[0099] The other MBMS services refer to oth...

Abstract

The invention discloses a method for monitoring notification information of MBMS (Multimedia Broadcasting Multicast Service) control channels, comprising the following steps of: in an MBSFN (Multicast Broadcast Single Frequency Network) cell comprising more than two MBMS MCCH (Multicast Control Channels), UE (User Equipment) determines whether a corresponding relation between the required MBMS service and the MCCH exists when determining that the required MBMS does not begin, and if so, only monitoring the notification information of the MCCH corresponding to the required MBMS; and if not, monitoring notification information of all MCCHs in the MBSFN cell. The invention simultaneously discloses a device for monitoring notification information of MBMS control channels. The invention ensures that the MBMS which does not begin currently is immediately received through the UE in the MBSFN zone overlapping cell.

Description

technical field [0001] The present invention relates to the monitoring technology of the control channel of Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service), in particular to the notification information of the Control Channel of Multicast Broadcast Multicast Service (MCCH, Multicast ControlCHannel) in a long-term evolution (LTE, Long Term Evolution) system The monitoring method and device, and user equipment. Background technique [0002] In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) proposed the multimedia broadcast and multicast service MBMS, which provides a point-to-multipoint data source to send data to multiple users in the mobile network services, realize network resource sharing, and improve the utilization of network resources, especially the precious air interface resources. In the LTE network, the MBMS technology is called Evolved Mu...
