Method for automatically switching WLAN (Wireless Local Area Network) and LTE (Long Term Evolution) network and communication terminal

Abstract

The invention discloses a method for automatically switching a WLAN (Wireless Local Area Network) and an LTE (Long Term Evolution) network and a communication terminal. The method comprises the steps of receiving signal measurement parameters reported by the WLAN and the LTE network; obtaining preset information of a network priority, wherein the network priority is used for identifying the network preferentially used for bearing communication service when the WLAN and the LTE network coexist; and performing switching operation according to the signal measurement parameters and the preset information of network priorities. According to the method and the communication terminal, the network with relatively good network condition in the WLAN and the LTE network can be automatically selected for bearing IMS (IP Multimedia Subsystem) communication service, the communication service quality can be ensured, and the network connection efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and a communication terminal for realizing automatic switching between WLAN (Wireless Local Area Networks, wireless local area network) and LTE (Long Term Evolution, long term evolution) networks. Background technique [0002] As the global coverage of the LTE network becomes more and more perfect, the IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) communication service carried by it also develops rapidly. However, the communication service quality of LTE networks in closed environments such as basements, subways, and high-rise buildings is often poor, and the network optimization technology in these places is very difficult and expensive. Since the coverage of WLAN in a closed environment is relatively complete and the cost is very low, currently, WLAN terminals can be connected to the mobile Internet through an LTE wireless router to achiev...

Problems solved by technology

However, the current switch between WLAN and LTE networks generally only depends on the preset information of network priority. For example, it is preset that WLAN is used to carry IMS communication services first. If a communication terminal enters an outdoor open area from a closed environment, the network condition of the LTE network is better than that of WLAN, at this time, the communication service is still carried by the WLAN with poor signal quality, which will not only affect the communication service quality, but also increase the network connection time, thereby reducing the network connection efficiency.
