Description
Technical Field
The application relates to a configuration method of a mobile communication network and a WLAN (wireless local area network) network of a 4G multi-mode mobile terminal.
Background
The development of Mobile communication technology starts from the first generation of analog cellular Mobile communication systems, to the second generation of Global System for Mobile communication (GSM) which provides voice service and low-rate data service under good network coverage conditions, to the third generation of Universal Mobile Telecommunications System (UMTS) which further provides more types of broadband multimedia services, and the introduction of LTE (Long Term Evolution) brings the Mobile communication technology into the 4G era.
A 4G multimode (multi mode) mobile terminal (UE) supporting GSM, UMTS, and LTE has been widely used. LTE provides high-rate data services, but also incurs high traffic tariffs. Deployment of WLAN (wireless LAN) networks is spread throughout homes, work environments and public places, and a considerable number of WLAN networks are available to users for free, and even a charged WLAN network has a traffic charge significantly lower than that of a 4G mobile communication network. In the situation that the 4G mobile communication network and the WLAN network simultaneously cover, the WLAN network can be preferentially used so as to avoid or reduce the traffic charge. This requires the mobile terminal to perform effective configuration on the access of the 4G mobile communication network and the WLAN network, including services such as accessing the internet, making and receiving calls, and sending and receiving short messages.
After the existing 4G multimode mobile terminal accesses the WLAN network, the mobile terminal still selects to be in the 4G mode for standby even if the mobile terminal is in the connected state of the WLAN network for a long time. This arrangement brings about the following disadvantages. First, a mobile terminal generally adopts a CSFB (Circuit Switched Fallback, Circuit Switched Fallback scheme) to implement a voice service in a 4G mode, that is, the Circuit Switched service needs to fall back to a 2G or 3G mobile communication network, so that a call setup delay of a calling voice and a called voice of the mobile terminal is longer than that of a 2G or 3G mobile terminal, and a call rate is also low. Secondly, the standby power consumption of the mobile terminal is larger when the mobile terminal is in standby in the 4G mode than when the mobile terminal is in standby in the 2G or 3G mode, which affects the service life of the mobile terminal.
