Embodiment Construction

[0026] The invention provides a method for a mobile communication terminal to maintain a data connection in an LTE network. When a user uses the current network for a data connection and moves to an environment where there is no current resident network, the data connection will not be interrupted.

[0027] According to the embodiment of the present invention, the mobile communication terminal reads the MCC (Mobile Country Code, mobile country code) and MNC (Mobile Network Code) of the SIM (Subscriber Identity Module) card when it starts searching the network after being turned on. code). After selecting an operator based on the SIM card, it starts searching for networks supported by the operator, including 4G, 3G and 2G networks. And preferentially reside on high-speed networks. At the same time, save the operator's network other than the network already resident in the terminal database as candidate target networks.

[0028] When the terminal completes the data connection, it s...

Abstract

The invention relates to a method for a mobile communication terminal to maintain a data connection in an LTE network. The method is used for maintaining data communication uninterruptable when the terminal enters an environment which is poorly covered by a network. When searching networks and dwelling on networks, the terminal obtains all networks which are supported by a current operator and saves the operator' other networks where the terminal does not dwell in the database of the terminal as alternative target networks; the terminal dwells on a preferential network at first to carry out data communication, when the terminal moves and finds that the quality of a current data connection tends to decline after a plurality of search, the terminal begins to search the alternative target networks saved in the preceding step; when the data connection of the preferential network where the terminal dwells currently is interrupted, the terminal dwells on an alternative target network so as to carry out data communication, and therefore, smooth data connections can be ensured; and the link quality of the preferential network where the terminal dwell previously is detected in real time, if the data connection of the preferential network can be restored, the terminal restarts to search networks and dwells on the preferential network to carry out data communication.

Description

Technical field [0001] The present invention relates to a mobile communication terminal, in particular to a method for the mobile communication terminal to maintain a data connection in an LTE network. Background technique [0002] With the popularization of smart phones, the rapid construction of 4G (4th Generation) networks, and the appropriate reduction of operators’ data traffic costs, more mobile communication terminal users are accustomed to keeping their smart phones connected to the network all the time in order to keep their phones connected to the Internet. Real-time intercommunication on the Internet. [0003] However, in places where 4G network construction such as tunnels, basements, and complex buildings are not complete enough, smartphones will continue to use the waiting characteristics of the data connection in the 3G era after a temporary interruption, which will cause mobile communication terminals to be temporarily unable to enter these buildings. Connect Netwo...
