Abstract

The invention discloses a network switching method, a terminal, a controller, a gateway and a system, belonging to the field of mobile communication. The method includes: when the terminal accesses the first network, converting the data containing the initial TCP quadruple into data containing the first TCP quadruple and sending it to the gateway; switching from the first network to the second network Afterwards, convert the data containing the initial TCP quadruple into data containing the second TCP quadruple and send it to the gateway. The present invention converts the data containing the initial TCP quadruple into data containing the first TCP quadruple before network switching, and converts the data containing the initial TCP quadruple into data containing the second TCP quadruple after the network switching. The data of the TCP quadruple achieves the goal of making the connection uninterrupted before and after the network switching, improving the user experience, and reducing the complexity of the network switching process.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network switching method, a terminal, a controller, a gateway and a system. Background technique [0002] With the continuous development of the mobile communication field, there are abundant mobile network resources around us, such as 3G, WiFi and WiMAX. Since the terminal can only use one network at the same time, when the terminal switches from one network to another, the network connection currently in use will be interrupted, thereby affecting user experience. Therefore, users urgently need a network switching method that can perform seamless switching. [0003] Please refer to figure 1 , which shows a schematic diagram of the network structure provided by the background technology of the present invention. Taking the terminal switching from the first network currently in use to the second network as an example, the existing network switching method is as follows: (1)...
