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

Embodiment Construction

[0089] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention.

[0090] The terminal in this embodiment of the present invention may be a user equipment UE, for example, a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a mobile internet device (English: mobile internet device, MID for short), a wearable device (for example, a smart watch (such as a smart watch). iWatch, etc.), smart bracelet, pedometer, etc.), can also be other devices that can be connected to the cellular mobile network, and the subsequent description can be described by taking the user equipment UE as an example. The user equipment in this embodiment of the present invention may access the network based on the dual-connection DC technology. The dual-connection technology involves the MCG and the SCG. The base station that provides the MCG is called the second ...

Abstract

The embodiment of the present invention discloses a communication method, related equipment, and system. The method is applied to a dual connectivity scenario. In the dual connectivity scenario, a terminal maintains a communication connection with a first base station on the network side through a first wireless resource link, respectively. and maintain a communication connection with a second base station on the network side through a second wireless resource link, the throughput of the first base station is higher than the throughput of the second base station, the method includes: the terminal acquires the first signal quality and the first Bandwidth; when the first signal quality is higher than the preset second signal quality, and the first bandwidth meets the requirements for carrying the service of the terminal, the terminal sends a link maintenance instruction to the network side, and the link maintenance instruction uses Instructing the second base station to configure the second radio resource link to be in a dormant state or a lightly connected state. By implementing the embodiment of the present 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 in particular, to a communication method, related equipment and system. Background technique [0002] Dual Connectivity (English: Dual Connectivity, referred to as: DC) in communication technology is a working mode of User Equipment (User Equipment, referred to as: UE) in the Radio Resource Control (English: Radio Resource Control, referred to as: RRC) connection state RRC_CONNECTED , the UE needs to access a master cell group (English: Master Cell Group, MCG for short) and a secondary cell group (English: Secondary Cell Group, SCG for short) in this working mode. If the base station (Evolved NodeB, eNB) in Long Term Evolution (English: Long Term Evolution, LTE) supports DC, the UE in the RRC_CONNECTED state can be configured to use the radio resources provided by two different eNBs, one as the primary base station ( English: master eNodeB, MeNB for short) provides MCG, one ...
