Abstract

The present invention provides an MTC (machine-type communication) terminal network search method, an MTC (machine-type communication) terminal network device and an MTC (machine-type communication) terminal. The method includes the following steps that: whether the MTC terminal needs to perform service interaction with a network is judged when no cells supporting MTC communication exist around the MTC terminal; and when the MTC terminal needs to perform service interaction with the network, the MTC terminal performs network search according to a timer progressive increase mode so as to search a cell where the MTC terminal can reside normally, the MTC terminal stops network search when finding a cell where the MTC terminal can reside normally, and the MTC terminal resides normally in the cell; and when the MTC terminal does not need to perform service interaction with the network, the MTC terminal stops network search and enters a sleep state. With the MTC (machine-type communication) terminal network search method and the MTC (machine-type communication) terminal network device of the invention adopted, the frequency of the network search of the MTC terminal can be decreased, and the power consumption of the MTC terminal can be saved.

Description

technical field [0001] The present invention relates to the field of MTC communication technology, in particular to a method and device for searching a network by an MTC terminal and an MTC terminal. Background technique [0002] With the rapid development of the Internet of Things, MTC (Machine-Type Communication, Machine Type Communication), as an important part of the Internet of Things, naturally attracts more and more attention. MTC communication. [0003] MTC communication refers to a communication mode between machines (devices and devices) without human participation, and MTC communication is also called M2M (Machine-to-machine, inter-machine) communication. [0004] In order to cope with MTC communication, 3GPP has optimized the LTE protocol itself to varying degrees, but so far, the LTE protocol has not optimized the scenario where there is no cell supporting MTC communication around the MTC terminal. The existing LTE protocol stipulates that when a UE (User Equi...
