Embodiment Construction

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0025] The present invention aims at the problem in the prior art that when performing a cell network search, the search is performed at a fixed time interval, thereby causing waste of power consumption of the terminal, and provides a cell network search method, device and terminal, which can determine the current state of the terminal Whether the registered first-type network cell is a cell where the terminal has camped and has not searched for the second-type network, and according to different judgment results, the second-type network is performed in the cell at different time intervals search, thereby avoiding the waste of terminal power consumption.

Abstract

Provided are a cell network search method and device, and a terminal. The method comprises: acquiring the type of a network which is currently registered by a terminal; when the type of the network is the first type of network, judging whether the first type of network cell which is currently registered by the terminal is a cell of the second type of network cell which the terminal has resided in and has not been found, wherein the data rate of the second type of network is greater than the data rate of the first type of network; and if the first type of network cell which is currently registered by the terminal is the cell of the second type of network cell which the terminal has resided in and has not been found, according to a pre-set first time interval, searching the second type of network in the cell, otherwise, according to a pre-set second time interval, searching the second type of network in the cell, wherein the first time interval is greater than the second time interval. By means of the technical solution provided in the present invention, the second type of network can be searched in the cell according to different time intervals, thereby avoiding the waste of the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell network search method, device and terminal. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) is a long-term evolution of UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) technology led by 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project). LTE is a transitional technology between 3G and 4G. It is the global standard of 3.9G. It adopts OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multi-input Multi-output) as its The only standard for wireless network evolution, which improves and enhances 3G air access technology. This technology centered on OFDM / FDMA (frequency division multiple access) can be regarded as a "quasi-4G" technology. Under the 20MHz spectrum bandwidth, it can provide the peak rate of downlink 100Mbit / s and uplink 50Mbit / s. It improves the per...
