Search method and device

Abstract

The invention relates to the technical field of communication, and discloses a network search method and a network search device. The network search method comprises the following steps: frequency bands of radio access technology (RAT) used by different channels are merged; a radio frequency device used in each band of each RAT is redistributed, and an RAT network search sequence is generated; parallel network search is carried out according to the network search sequence, and the distributed radio frequency device is used for parallelly receiving the network search data of the corresponding RAT; and if any RAT network search succeeds, the searched network is recovered. Thus, the network search process by each RAT in turn in the case of no network can be quickened, the radio frequency device opening time is compressed, the network search power consumption can be effectively reduced, and the terminal standby time is prolonged. When any RAT network signal appears in the environment, the time from a non-network environment to network recovery by the terminal is effectively shortened, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for searching a network. Background technique [0002] The dual-pass terminal has two sets of independent radio frequency devices, which can work simultaneously without time division. So each pass is an independent work, not affected by another pass, specifically as figure 1 As shown, the dual-pass terminal includes 4 waits (two waits 0 and two waits 1), two passes (pass 0 and pass 1) and two radio frequency devices (radio frequency device 0 and radio frequency device 1). figure 1 It describes the standby, active, and radio frequency devices ( RFID) mapping relationship. [0003] Here is an explanation of the meaning of "waiting" and "passing". A wait can only correspond to 1 pass; a pass can have multiple waits. The number of channels actually corresponds to the number of RF channels in the front end. The following is an example to illustrate. Fo...

Problems solved by technology

However, the multiple sets of radio frequency devices owned by the dual-pass terminal work independently without time division, and the power consumption is much greater than that of the single-pass terminal; in the absence of a network environment, each pass of the terminal needs to frequently search the network, although each pass The radio frequency devices are controlled independently, and the search of the network corresponding to each RAT is also carried out serially and orderly under this pass. The receiving duty cycle is very large, which is not good for the power consumption of the terminal, which will shorten the standby time of the terminal

In addition, the RATs and their frequency bands (related to the capabilities of radio frequency devices) supported by each channel overlap to a large extent. When each channel independently searches the network without a network, it performs repeated network searches and does not share the search information between the channels. Net results, waste of resources
