Embodiment Construction

[0025] In order to solve the problem of complicated implementation of the switching algorithm between the cellular mobile communication network and the Wi-Fi network, the present invention provides a flow-based network switching method, device, and terminal. The following is combined with the accompanying drawings and embodiments. The invention is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, but do not limit the present invention.

[0026] In Transmission Control Protocol / Internet Protocol (TCP / IP), the TCP protocol uses a three-way handshake to establish a connection in order to provide reliable connection services. After the connection is established, when transmitting data packets, the sender needs to confirm (response) each time a data packet is sent by the receiver. If the receiver successfully receives the data packet, it will send an acknowledgement (Acknowledgement, ACK) t...

Abstract

The invention discloses a flow-based network switching method, device and terminal. The method includes: performing network access based on multiple preset networks to access one of the multiple networks; and determining whether to perform network switching based on the number of data packets transmitted in the accessed network. ; If yes, switch the accessed network to another network; the other network is included in the one or more networks; if not, continue to determine whether to perform network switching. The present invention effectively solves the problem of complicated implementation of the switching algorithm between the cellular mobile communication network and the Wi-Fi network. Based on the TCP / IP protocol, the invention determines whether the data flow is too large by monitoring the data packets sent and received, and adaptively performs network switching when the data flow is large, thereby improving the convenience of the network switching method.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a flow-based network switching method, device and terminal. Background technique [0002] Cellular mobile communication adopts cellular wireless networking mode, which connects terminals and network devices through wireless channels, so that users can communicate with each other during activities. The cellular mobile communication network has wide coverage and can meet the high mobility of the terminal. However, the data transmission rate in the cellular mobile communication network is not high. [0003] Wi-Fi is an important part of a wireless local area network (Wireless Local Area Nerworks, WLAN). Wi-Fi is a technology that connects multiple terminals to each other in a wireless manner, and has a high data transmission rate. [0004] Cellular mobile communication networks can take advantage of the high data transmission rate of Wi-Fi to make up for their own lim...
