Description

A network search method and device for a single-card dual-standby mobile terminal public land mobile network

technical field

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

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.

With the rapid development and maturity of multi-standards, operators are building and investing in various standard networks faster and faster, thus a multi-standard coexistence mode appears. In order to make full use of the advantages and investment of existing technologies and provide users with the best service experience under the condition of the gradual development of new technologies, single-card multi-mode multi-standby digital mobile terminals have become a terminal form in response to the situation. The single-card multi-mode multi-standby digital terminal can be on standby in multiple modes at the same time without changing the terminal card interface, and user services can be selected to be carried out in the business optimal mode.

However, compared with the traditional single-standby terminal, the two service domains of the multi-standby terminal may be registered in two modes, or may be registered in one of the modes because a certain mode cannot provide service support. However, the current mobile technology only requires to store the last registered PLMN (RPLMN) information, and there is no corresponding access technology (RAT) information. When the terminal is restarted, try to use RPLMN to search the network and register in the two modes respectively. If the RAT of the RPLMN does not match this mode, it will cause a waste of PLMN network search and registration time.

At the same time, the two service domains of the redundant terminal may be registered on the PLMN of the same operator, or may be registered on the PLMN of different operators, so that the information of different operators can be correctly displayed, service billing, and user service consumption choices Wait for a series of questions.
