[0177] refer to figure 1 As shown, the method for automatic terminal switching in the embodiment of the present invention is applied to the base station, including:

[0178] Step 101: Send a measurement configuration message prepared for automatic handover to the terminal, and detect the acquired measurement report prepared for automatic handover sent by the terminal.

[0179] Here, the source base station sends a measurement configuration message prepared for automatic handover to the terminal, wherein the measurement configuration message prepared for automatic handover includes measurement object configuration and measurement report condition configuration prepared for automatic handover. The terminal performs channel measurement according to the measurement configuration message prepared for automatic handover, and sends a measurement report to the source base station when the measurement report condition prepared for automatic handover is met. In practical applications, ...

[0284] The embodiment of the present invention is a specific application embodiment of the above-mentioned first embodiment. The embodiment of the present invention specifically describes the process of the source base station activating the terminal automatic handover function and the source base station initiating automatic handover preparation. In the embodiment of the present invention, the source base station separately configures trigger conditions (i.e. configures measurement report conditions) for activating the terminal automatic handover function and initiating automatic handover preparations, wherein there is no strict sequence for activating the terminal automatic handover function and initiating automatic handover preparations, namely The base station may send the measurement configuration for activating the automatic handover function of the terminal to the terminal before or after sending the measurement configuration for automatic handover preparation.

[0324] The embodiment of the present invention is a specific application embodiment of the above-mentioned first embodiment. The embodiment of the present invention specifically describes the process of the source base station activating the terminal automatic handover function and the source base station initiating automatic handover preparation. In the embodiment of the present invention, the source base station configures the same trigger condition (that is, configures the measurement report condition) for activating the terminal automatic handover function and initiating automatic handover preparation, and simultaneously activates the terminal automatic handover function and initiates automatic handover preparation.

Abstract

The present invention provides a method, a base station and a terminal for automatic terminal switching, which relates to the field of communications and solves the problem that the existing technology does not stipulate the time when the source base station initiates switching preparation in the automatic switching of the terminal, resulting in invalid switching preparation and increasing the X2 signal. The problem of cost. The method is applied to a base station and includes: sending a measurement configuration message for automatic switching preparation to a terminal, and detecting the obtained measurement report sent by the terminal for automatic switching preparation; and determining whether the terminal supports the measurement report based on the received measurement report for automatic switching preparation. When the automatic switching function is enabled, an automatic switching request is sent to the target base station that requires automatic switching preparation; wherein, the measurement configuration message for automatic switching preparation includes the measurement object configuration and measurement report condition configuration for automatic switching preparation. The solution of the present invention effectively determines the time to initiate handover preparation, and avoids the problem of increased X2 signaling overhead caused by the source base station making invalid handover preparation.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal automatic switching method, a base station and a terminal. Background technique [0002] MF (Multe Fire) is a wireless access technology that extends LTE (Long Term Evolution, Long Term Evolution) to unlicensed frequency bands. In this technology, unlicensed frequency band carriers can provide services independently without using licensed frequency band carriers. In order to fairly occupy the unlicensed frequency band channel with other devices in the unlicensed frequency band (such as WiFi devices) and avoid mutual interference between unlicensed frequency band devices, the MF physical layer introduces a carrier-sensing technology similar to WiFi (LBT, Listen Before Talk )mechanism. When the base station or terminal detects that the unlicensed frequency band channel is occupied, that is, when the LBT fails, it stops sending signals, and when it detects that the chan...
