Problems solved by technology

However, when the mobile terminal (User Equipment, UE) is located in a relatively harsh communication environment, such as in a basement, an elevator, etc., it may occur that the signal quality of all cells is very poor, which will cause the current serving cell to fail to continue Carrying business, but unable to meet the preset switching conditions, which will cause the mobile terminal to go off-net, and further lead to the inability to communicate

Embodiment Construction

[0038]As mentioned in the background technology, when the mobile terminal is located in a relatively harsh communication environment, the signal quality of all cells may be very poor, which will cause the current serving cell to be unable to continue to carry services and fail to meet the preset handover Conditions, which in turn will cause the mobile terminal to go offline, and further lead to a situation where communication cannot be performed.

[0039] MTC is introduced in the version (release) 13 / 14 of the 3GPP protocol, mainly for the Internet of Things technology, which can include enhanced machine type communication (Enhanced Machine Type Communication, EMTC) and micro machine type communication (Femto Machine Type Communication, FeMTC) , the MTC cell may also be called an IoT cell.

[0040] When the MTC cell is initially designed, it is oriented to the machine type terminal, and the network side usually only delivers the information list of the MTC cell to the machine ...

Abstract

The present invention provides a cell switching method and device. The cell switching method includes: sending an information list of an MTC cell to a terminal, so that the terminal measures the signal quality of the MTC cell according to the information list of the MTC cell; receiving the The signal quality of the MTC cell reported by the terminal; determine the relationship between the signal quality of the MTC cell, the signal quality of the serving cell of the terminal, and the signal quality of the neighboring cell, when the relationship between the three satisfies the first When a preset condition is set, instruct the terminal to switch to an MTC cell; wherein, the serving cell of the terminal is a non-MTC cell. The method and device can improve the reliability of the cell switching method.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method and device. Background technique [0002] In the current cellular communication system, the mobile terminal can perform cell switching according to the instructions of the base station. However, when the mobile terminal (User Equipment, UE) is located in a relatively harsh communication environment, such as in a basement, an elevator, etc., it may occur that the signal quality of all cells is very poor, which will cause the current serving cell to fail to continue Bearing services, but failing to meet the preset handover conditions, the mobile terminal will be disconnected from the network, and further lead to the inability to communicate. Contents of the invention [0003] The technical problem solved by the invention is to improve the reliability of the switching method. [0004] In order to solve the above-mentioned technical problems, an embodimen...
