Single card terminal and network reselection method

Abstract

The embodiment of the invention discloses a single card terminal and a network reselection method. The terminal comprises a 2G processing module and a 3G processing module, wherein the 2G processing module is used for residing a circuit switched (CS) domain in a 2G network preferentially and executing CS domain services; the 3G processing module is used for residing a packet switched (PS) domain in a 3G network preferentially and executing PS domain services; the 3G processing module is also used for detecting 3G network signal intensity; and when the 3G processing module detects that the 3G network signal intensity is not higher than a first threshold and lasts for a first time, the 2G processing module is also used for judging whether the 2G network accords with the PS domain residence condition, if so, the PS domain is resided in the 2G network, and the PS domain services are executed in the 2G network. According to the embodiment of the invention, the PS domain and the CS domain can be resided in different modules respectively, and CS domain services and the PS domain services are given consideration; meanwhile, the network reselection process is accelerated, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a single-card terminal and a network reselection method. Background technique [0002] In the field of wireless communication technology, 2G network and 3G network are two widely used networks. Services based on 2G networks and 3G networks mainly include voice services and data services, wherein voice services are carried by the circuit switched domain (CS domain, Circuit Switched Domain), and data services are carried by the packet switched domain (PS domain, Packet Switched Domain). Bearer, both 2G network and 3G network support CS domain service and PS domain service. The aforementioned CS domain or PS domain can be understood as a collection of software and hardware for processing CS domain services (such as voice services) or PS domain services (such as data services). [0003] Compared with 2G network, 3G network is a new network with larger bandwidth and better da...

Problems solved by technology

[0016] When the existing single-card dual-mode terminal reselects from one network to another, there will be a period of time when the service is unavailable, that is, the service will be interrupted during this period, whether it is a CS domain service or a PS domain. no business

At the same time, since the process of reselecting to a different system network needs to search for different system network signals and perform judgment and sorting, this process cannot be completed in a short time, which increases the time when services are unreachable and affects user experience.
