specific Embodiment 1

[0070] For Scenario 1, each cell can be pre-configured with its corresponding SAI related information by OAM (corresponding to the aforementioned multicast broadcast service area configuration information, and corresponding to the subsequent multicast broadcast related information), and then the base station informs the MCE or AMF of the multicast Broadcasts the SAI-related information corresponding to the control network element. Specifically, the following information interactions may be included:

[0071] The base station sends multicast broadcast related information to the MCE or other multicast broadcast control network elements, which includes at least one of the following information: gNB ID, gNB Name, cell NCGI list, and the multicast broadcast service area list service area corresponding to each cell list. Each service area entry in the multicast broadcast multicast / broadcast service area list includes multicast / broadcast service area identifier and / or multicast / broa...

specific Embodiment 2

[0077] For Scenario3, it may be considered to transmit the corresponding multicast / broadcast service area information during the multicast / broadcast session establishment process.

[0078] Specifically, when the multicast / broadcast session is established, the following information sending methods may be considered: BMSC to multicast / broadcast GW, multicast / broadcast GW to AMF, AMF to MCE, MCE to gNB, or BMSC to multicast / broadcast The broadcast GW, the multicast / broadcast session establishment request message sent by the multicast / broadcast GW to the AMF, and the AMF to the gNB may include multicast broadcast related information. The multicast broadcast related information may include at least one of the following information: multicast / broadcast service identification information, multicast / broadcast session id, multicast / broadcast service area, multicast / broadcast cell list. The multicast / broadcast service identifier can identify a multicast / broadcast service or multicast / br...

specific Embodiment 3

[0084]For Scenario 2 and 4, it is necessary to consider the multicast / broadcastservice area where overlap may occur. For this situation, the following possible handling methods can be considered:

[0085] Method 1: For the same multicast / broadcast service, configure different multicast / broadcast service identifiers (or TMGI or other identifiers for identifying multicast / broadcast services or bearer services) for different multicast / broadcast service areas with overlap ),Such as Figure 6 Shown in (c) process.

[0086] Establish a multicast / broadcast session corresponding to different TMGIs between UPF / multicast / broadcast GW and gNB, and establish a GTP-U tunnel. This method greatly increases the configuration requirements of multicast / broadcast service identifiers. For a certain base station, this means that multiple multicast / broadcast service areas corresponding to the overlap of the same multicast / broadcastservice establish multicast / broadcast sessions and GTP- U tunnel....

Abstract

The invention provides a multicast broadcast information transmission method and device, a storage medium and an electronic device, and the method comprises the steps: transmitting first multicast broadcast information comprising multicast broadcast service region configuration information to a first network element; alternatively, receiving second multicast broadcast information containing multicast broadcast service area configuration information from the first network element. Through application of the method and the device, the problem of configuring the service area of the multicast broadcast in related technologies is solved.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a method, device, storage medium and electronic device for transmitting multicast broadcast information. Background technique [0002] With the continuous development of 5G (5th generation mobile networks, fifth-generation mobile communication technology), 5G solutions for various application scenarios are accelerating their completion. The multicast broadcast service scenario is a traditional service scenario that exists to meet the needs of most users for the same service. [0003] The 5G-related technologies that have been discussed and standardized in the industry are mainly about unicast service scenarios, that is, the PTP (Point to Point, point-to-point) service mode. And PTM (Point to multipoint, point to multipoint) standardization discussion of the service mode has not yet started. In addition, with the rapid growth of users and multi-dimensional application sce...
