A management method of a user terminal and related equipment

Abstract

The embodiment of the present invention discloses a user terminal management method and related equipment, wherein the method may include: after receiving the first request message for requesting the UE to enter the target state, the MME may initiate a first process to make the UE enter the target state. The UE enters the target state. In the target state, there is an RRC connection between the UE and the source base station, but there is no DRB, and there is no S1-U bearer for the UE between the source base station and the serving gateway. This can not only meet the requirement that the UE needs to be in the RRC connected state when performing V2X services, but when the serving base station of the UE changes, only the context of the UE needs to be transferred between the source base station and the target base station, and there is no need to re-establish the DRB. , the SGW does not need to modify the S1-U bearer of the UE, so that the signaling load on the network side during the handover process of the UE in the ECM connected state can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile communication technologies, and in particular to a method for managing user terminals and related equipment. Background technique [0002] The IoV is based on the Intra-Vehicle Network, the Inter-Vehicle Network, and the Vehicle-to-Mobile Internet, and performs wireless communication and information exchange between the vehicle and the outside world (Vehicle to X, V2X) in accordance with agreed communication protocols and data interaction standards. The system network can realize intelligent traffic management, intelligent dynamic information service and intelligent vehicle control. Among them, X includes vehicles, roads, pedestrians and the Internet. [0003] In the Internet of Vehicles, when a user terminal (User Equipment, UE) performs V2X data services, the core network side, that is, the evolved packet system (Evolved Packet System, EPS) mainly has two resource scheduling methods,...

AI Technical Summary

Problems solved by technology

Considering the high mobility of vehicles, when performing V2X services, the UE's serving cell will inevitably change frequently, which will lead to frequent handovers

During the handover process, a large amount of signaling will be generated on the network side, which will cause serious signaling load to the network.
