Problems solved by technology

[0004] However, after the deployment of the fifth-generation mobile communication technology (English: 5th-Generation, 5G for short) network, the MCG in the Tight interworking mode using the DC mode adopts the LTE technology, and the SCG adopts the 5G technology. The technology will be different in throughput and delay, which will cause the network to frequently switch to and exit the DC state. The switch to the DC state is accompanied by the establishment of the link, and the exit from the DC state is accompanied by the deregistration of the link; the UE is in the MCG The establishment or deregistration of the link in the / SCG requires interactive signaling between the MeNB / SeNB and the CN. Therefore, when 5G technology and LTE technology are involved in the DC, the number of interactive signaling between the MeNB / SeNB and the CN will be significantly increased. Greatly increased communication overhead

Abstract

Disclosed in an embodiment of the present invention are a communication method, related device and system. The method is applied to a dual-connection scenario in which a terminal maintains a communication connection with a first base station at a network side through a first radio resource link and maintains a communication connection with a second base station at the network side through a second radio resource link. The method comprises the steps that the terminal obtains first signal quality and first bandwidth; when the first signal quality is higher than a preset second signal quality and the first bandwidth meets the requirement for bearing the service of the terminal, and the terminal sends a link maintenance instruction to a network side, wherein the link maintenance instruction is used for instructing the second base station to configure the second wireless resource link to be in a dormant state or a light connection state. By implementing the embodiment of the invention, the communication overhead between the base station and the core network can be saved.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a communication method, related equipment and system. Background technique [0002] Double connections in communication technology (English: DUAL Connectivity, abbreviation: DC) is a user equipment (UEQUIPMENT, ACT) in wireless resource control (English: Radio Resource Control, abbreviation: RRC) Connection RRC_CONNECTED Under UE needs to access a primary cell group in this working mode (English: Master Cell Group, abbreviation: MCG) and a secondary group (English: Secondary Cell Group, abbreviation: SCG). If a long-term evolution (English: Long Term EVOLUTION, EVOLVED NODEB, CRM: eNB) supports DC, the RRC_CONNECTED-state UE can be configured to use two different eNBs provided wireless resources, one as the primary base station ( English: Master ENODEB, referred to as: meNB) Provides MCG, one as a secondary base station (English: SECONDARYENB, abbreviation: SE...
