Embodiment 1

[0169] Embodiment 1. When the CP and UP in the CU are deployed separately, if the UE in the UE information list is a UE that cannot receive the MBMS service that is being broadcast and / or will be broadcast (that is, the MBMS service that the UE requests to broadcast), please refer to Figure 6 The reporting process of MBMS auxiliary information provided by the embodiment of the present invention Figure 1 .

[0170] Step 601: When the set trigger condition is reached, the DU collects the UE information that cannot receive the MBMS service, and obtains the UE information list.

[0171] It should be noted that the MBMS service here refers to the MBMS service that can send service data in multicast mode, and the service data of the MBMS service is being and / or will be sent to UE.

[0172] When the preset trigger condition is met, the DU counts the UE information that cannot receive the MBMS service, and obtains the UE information list, as shown in Table 3. The preset trigger c...

Embodiment 2

[0187] Embodiment 2. When the CP and UP in the CU are deployed, if the UE in the UE information list is receiving and / or about to receive the MBMS service, but the transmission quality of the channel used by the UE is poor, please refer to Figure 7 The reporting process of MBMS auxiliary information provided by the embodiment of the present invention Figure II .

[0188] Step 701: When the set trigger condition is reached, the DU counts the information of UEs receiving MBMS services but with poor transmission quality, and obtains a list of UE information.

[0189] It should be noted that the MBMS service here refers to the MBMS service that can send service data in multicast mode, and the service data of the MBMS service is being and / or will be sent to UE.

[0190] When the preset trigger condition is reached, the DU counts the information of UEs receiving or about to receive MBMS services but with poor channel quality, and obtains a list of UE information, as shown in Tab...

Embodiment 3

[0205] Embodiment 3. When the CP and UP in the CU are deployed in the same physical entity, the UEs in the UE information list are receiving MBMS services, but the transmission quality of the channel is poor. Please refer to Figure 8 The reporting process of MBMS auxiliary information provided by the embodiment of the present invention Figure three .

[0206] Step 801: When the set trigger condition is reached, the DU counts the information of UEs receiving MBMS service orders with poor transmission quality, and obtains a list of UE information.

[0207] It should be noted that the MBMS service here refers to the MBMS service that can send service data in multicast mode, and the service data of the MBMS service is being and / or will be sent to UE.

[0208] When the preset trigger condition is reached, the DU counts the information of UEs receiving or about to receive the MBMS service single channel with poor quality, and obtains the UE information list, as shown in Table 5....

Abstract

The invention discloses a method, device and storage medium for reporting MBMS auxiliary information, which are used to solve the technical problem of low utilization rate of air interface resources in the execution of MBMS services in the prior art. Including: when the set trigger condition is reached, the UE information corresponding to each multimedia broadcast multicast MBMS service that the base station is broadcasting and / or the UE requests the base station to broadcast is collected, and the UE information list is obtained; wherein, the UE information includes the UE is receiving The transmission mode configured by the requested or requested MBMS service, one MBMS service in the UE information list corresponds to at least one UE information; then, report the MBMS auxiliary information carrying the UE information list to the centralized network unit CU of the base station; where , the MBMS assistance information is used to instruct the CU to evaluate the transmission mode configured for the MBMS service corresponding to each UE in the UE information list.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and storage medium for reporting MBMS auxiliary information. Background technique [0002] In a wireless communication system, there are scenarios where multiple user terminals request the same downlink service data, such as watching a live sports event, which requires the network side to send multiple copies of the same downlink data to multiple user terminals, thereby increasing the operating cost of the network side . [0003] In the existing technology, in order to reduce operating costs and deepen the mutually beneficial cooperative relationship between the wireless communication system and the source of the live video, the industry has proposed the "multicast" function, which allows the network side of a wireless cell to use specific wireless resources to send a single A share of downlink data, and multiple user terminals receive and decode the downlink d...
