Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0046] In this embodiment, a method for a multi-mode single-standby terminal to determine an effective cell, such as figure 1 shown, including:

[0047] After receiving the priority information of more than one frequency point sent by the network side, the multi-mode single-standby terminal in TD-SCDMA mode combines the received information of optional neighboring cells, according to the signal condition of the serving cell, Select a frequency point or all frequency points with a higher priority than the current serving cell from the above-mentioned one or more frequency poi...

Abstract

The invention discloses a method for determining an effective cell by a multi-mode single-standby terminal, and the multi-mode single-standby terminal. The method comprises the following steps that: after receiving the priority information of more than one frequency point, which is sent by a network side, the multi-mode single-standby terminal in a time division-synchronous code division multiple access mode selects a frequency point of which the priority is higher than that of a current service cell from more than one frequency point or all frequency points according to the received optional information of a neighbor cell and the signal condition of the service cell, takes the neighbor cell which corresponds to each selected frequency point as the effective cell to be reselected, and measures the effective cell. By the invention, the measurement time of the terminal is saved, and the power of the terminal can be saved. Moreover, by identification and determination of the effective cell, a reselection flow of the terminal is optimized, and reselection back-off caused by failure in reselection of a cell which is measured, evaluated and reselected by the terminal under the conditions of inadmissibility or full load is avoided.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for a multi-mode single-standby terminal to determine an effective cell and the multi-mode single-standby terminal. Background technique [0002] At present, most cities in China have built TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) networks, so the TD-SCDMA network has relatively complete coverage. Although the coverage and quality of TD-SCDMA network is still far behind that of GSM (Global System of Mobile communication, Global System for Mobile Communication) network, TD-SCDMA and GSM have basically achieved the same coverage in most cities. [0003] With the development of 4G technology, after LTE (Long Term Evolution, referred to as LTE) is introduced into the existing network, there may be 4G / 3G / 2G network coverage, 4G / 2G coverage, and 4G / 3G coverage. In the case of coexistence of multiple systems, a multi-mode single-standby t...
