example 1

[0044] Example 1: a first network using a Single-Frequency Network (Single-Frequency Network, SFN) for transmission, a second network using a non-SFN for transmission, or vice versa. In this example, the base stations, TRPs, access points (Access Point, AP) or antennas constituting the first network and the second network may be the same or different; The frequency points corresponding to the networks may be the same or different.

[0045] Among them, SFN transmission can refer to: multiple cells or multiple TRPs send the same signal, there is no co-channel interference between different cells, and multiple signals can improve SINR, transmission quality and coverage effect. Multiple cells constituting the SFN may share one cell ID (cellID), that is, supercellID. Multiple cells can transmit signals through SFN transmission. For example, each cell transmits with a wide beam, and a terminal device can receive the wide beams transmitted by multiple cells at a certain moment, ther...

example 2

[0046] Example 2: Use a first network with a relatively low frequency and a second network with a relatively high frequency, or vice versa. For example, the frequency point corresponding to the first network is 700MHz, and the frequency point corresponding to the second network is 4.8GHz.

example 3

[0047] Example 3: A first network with a relatively high antenna height and a second network with a relatively low antenna height, or vice versa. For example, the base station, TRP, AP or antenna of the first network is relatively higher than the base station, TRP, AP or antenna of the second network; for another example, the antenna of the first network is placed on a Qualcomm balloon, drone, airship or satellite , the antenna of the second network is placed on the ground station; for another example, the antenna of the first network is placed on a steel tower with a height of 100 meters, and the antenna of the second network is placed on a roof with a height of 10 meters.

Abstract

The invention discloses a network switching method, device and equipment, and belongs to the field of communication. The method comprises the following steps: the terminal equipment determines a second signal corresponding to a second network according to a first signal corresponding to a first network; wherein the first signal and the second signal respectively comprise at least one of a reference signal and a synchronization signal; and the terminal device measures the second signal. By adopting the embodiment of the invention, the number of signals needing to be measured can be reduced, and the measurement time can be shortened, so that the switching from the first network to the second network can be completed more quickly, and the network switching efficiency is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a network switching method, device and equipment. Background technique [0002] In mobile communication systems, such as Long Term Evolution (LTE) systems and New Radio (NR) systems, etc., user equipment (User Equipment, UE) can also be called terminal equipment, user terminals, and mobile terminals. etc.) When it is necessary to switch from one network to another, it may be necessary to measure multiple synchronization signal blocks (Synchronization Signal and PBCH block, SSB) of multiple cells under network coverage, which is time-consuming and laborious, and affects the efficiency of network switching . Contents of the invention [0003] Embodiments of the present application provide a network switching method, device, and equipment, so as to solve the problem of low network switching efficiency. [0004] In a first aspect, a network switching method is provided, th...
