Abstract

The invention relates to a network searching method for a single-card dual-standby mobile terminal public land mobile network (PLMN). The PLMN is selected by utilizing the information of the same subscriber identity module (SIM) card, and an optimal network is rapidly resided. In addition, the invention also relates to a network searching device for the single-card dual-standby mobile terminal PLMN. The network searching device comprises a terminal nonvolatile memory, a single-card dual-standby terminal universal module, a communication mode management module, a multi-standby PLMN selection and management module, a searching module under multiple modes and a man-machine interface. The PLMN network searching time under a prior mode in a service domain can be shortened on the premise of the optimal service experience, and two services are resided in the same operator network to the greatest extent, so that the information display of the operator is simplified, the charge accounting of the operator is convenient, and the service consumption of the user is convenient.

Description

technical field

[0001] The invention relates to mobile communication terminal related technologies, in particular to a single-card dual-standby mobile terminal public land mobile network (PLMN) selection technology. Background technique

[0002] With the rapid development of mobile communication, mobile communication has developed from the initial analog communication technology to the 2G network of digital communication technology. The 2G network can provide high-quality voice services, but can only provide low-speed data services. With the development of data services, users have higher and higher requirements for speed, and 3G networks that can provide high-speed services have emerged. Until now, the commercialization of 4G networks with an all-IP network architecture that can provide high-speed data services is also increasing. getting closer.

[0003] With the rapid development and maturity of multi-standards, operators are building and investing in various standard ne...
