Embodiment Construction

[0134] see figure 1 , figure 1 It is a schematic architecture diagram of the first application scenario. In this scenario, the low-frequency node 11 and the high-frequency node 12 are taken as nodes for illustration. Such as figure 1 As shown, in the high-frequency assisted low-frequency networking architecture, it mainly includes low-frequency nodes 11 , high-frequency nodes 12 and terminal devices 13 . The low-frequency node 11 generally adopts the traditional cellular frequency band, for example, the cellular frequency band may be 2.4GHz, or uses the millimeter wave frequency band, and the millimeter wave frequency band reaches the target interactive control plane of a relatively large area at a relatively low frequency, wherein, with a low The millimeter wave band of frequencies may be, for example, 6 GHz. The low-frequency node 11 may perform corresponding signaling interaction with the high-frequency node 12 or the terminal device 13 by using the cellular frequency b...

Abstract

Embodiments of the present invention provide a method for switching between high and low frequencies, and a method and device for configuring a terminal. The high-low frequency switching method includes that the high-frequency node detects the end of business data transmission with the terminal device, and obtains fallback-related information by exchanging messages with the low-frequency node, thereby generating a fallback configuration message and sending it to the terminal device, and the terminal device responds accordingly. Retreat to the low-frequency cell to avoid the problems of frequent cell switching and beam scanning caused by the terminal device staying in the high-frequency cell. The embodiments of the present invention can save the energy consumption of the terminal device and improve the battery life of the terminal device.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a high-low frequency switching method, a method and a device for configuring a terminal. Background technique [0002] Future fifth generation mobile communication system (5 th -Generation, 5G) needs to support huge mobile data traffic growth, massive device connections, various new services and application scenarios, for example, 3GPP (Third Generation Partnership Project) identified three typical application scenarios including: Enhanced Mobile Broadband (Enhanced Mobile Broadband, eMBB), Massive Machine Type Communications (mMTC), Ultra-Reliable and Low Latency Communications (URLLC). 5G systems need to have better performance, for example, larger system capacity, lower latency, higher network reliability, and better network availability. The 5G system will be able to conveniently realize the vision of intelligent interconnection between people and everyth...
