The terminal module and the method for selecting the target operator in the weak network scenario

Abstract

This application provides a method for selecting a target operator in a weak network scenario, including the steps: the terminal module uses the terminal's own radio frequency capability to scan the available network cells of each operator in the nearby area without a user identification card; Operators can perform signal measurement on available network cells to obtain signal measurement values; calculate signal quality values ​​of each operator based on signal measurement values ​​of available network cells of each operator; select target operators based on signal quality values ​​of each operator; and Switch Subscriber Identity Card to said target operator and perform network connection and registration. The present application also provides a terminal module for selecting a target operator in a weak network scenario. This application can select a suitable operator according to the signal quality of the local operator.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a terminal module and a method for selecting a target operator in a weak network scenario. Background technique [0002] During the camping process of an existing device in a network cell, the base station will determine whether the current device supports camping in the network cell by authenticating the authentication parameters of the Universal Subscriber Identity Module (USIM) uploaded by the device. The right parameters are generally stored in the user identification card, so in many cases, the device will first determine whether there is a user identification card before the registration process starts. If there is no user identification card, the device will not initiate the registration network process. However, in real life, the base station coverage of each operator is different in each area. For example, in some areas, China Unicom’s base s...

Problems solved by technology

However, in real life, the base station coverage of each operator is different in each area. For example, in some areas, China Unicom’s base station has high coverage and good signal quality, and in some areas, China Mobile’s base station has high coverage and good signal quality. , leading to some areas, such as underground parking lots, interiors of large shopping malls, urban high-rise dense areas and other areas, the base station coverage of some operators is low and the signal quality is poor, but the base station coverage of other operators may be relatively high, and the signal quality Relatively good; in this case, the device needs to select the appropriate operator to use the service according to the actual network situation
