Abstract

The invention provides a network switching method and system during conversation service processing. The network switching method comprises that when a first terminal determines that the conversation process of a second terminal needs to be changed from the first network to the second network, the same conversation data is sent to the second terminal via the first network and the second network simultaneously; an IP multimedia subsystem, to which the second terminal belongs, receives the conversation data sent from the first terminal, and back feeds data synchronization information to a base station; the base station determines whether the conversation data is synchronized according to the data synchronization information, and if not, the data synchronization information is sent to an access point; according to the data synchronization information, the access point and / or the base station adjust(s) transmission resource distributed to the first terminal, so that the conversation data, which is sent from the first terminal to the second terminal via the first network and the second network, is synchronized; and when the base station determines that the data synchronization information is synchronized, the first terminal is notified to disconnect from a network entity of the first network, and network switching is completed.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a network switching method and a network switching system for processing call services. Background technique [0002] At present, smart terminals have been widely popularized, but smart terminals consume a lot of traffic. Compared with the traffic of expensive mobile communication networks (such as LTE (Long Term Evolution, Long Term Evolution) networks), Wi-Fi (Wireless Fidelity, wireless security True) network is favored by users because of its low traffic cost. Considering users' needs for Wi-Fi networks, operators have also introduced the function of making calls based on Wi-Fi networks, that is, WFC (Wi-Fi Calling). [0003] However, the Wi-Fi network also has the problems of small coverage and poor mobility. Therefore, the integration development of Wi-Fi network and mobile communication network will be the next development direction. Although there are mobile ter...
