Embodiment 1

[0055] Such as image 3 as shown, image 3 It is a flow chart of a method for constructing a dual-channel hybrid tunnel for a mobile terminal provided in Embodiment 1 of the present application. This method is the operation process of the mobile terminal when two physical channels are enabled for the virtual tunnel connection, including:

[0056] S101: Establish a TCP connection with the 3G channel between the TAM.

[0057] Specifically, the mobile terminal issues an instruction to open a virtual tunnel connection, sends a connection request to port 45654 of the TAM through the 3G physical channel, and establishes a TCP connection in the Socket mode:

[0058] Socket (source IP: Addr_3G_MBT, destination IP: Addr_EN_TAM, source port: ephemeral port, destination port: 45654)

[0059] Wherein, source IP: Addr_3G_MBT, destination IP: Addr_EN_TAM, source port: temporary port, destination port: 45654 four parameters are the parameters that Socket program establishes TCP connection...

Embodiment 2

[0097] On the basis of Embodiment 1, this application provides another high-speed tunnel access method for wireless network mobile terminals, such as Figure 5 As shown, the method includes:

[0098] S301: Establish a TCP connection with the 3G channel between the TAM.

[0099] S302: Send a request message requesting to allocate an IP address for a tunnel connection to the TAM through the TCP connection of the 3G channel.

[0100] S303: Receive the tunnel connection IP address allocated according to the request information sent by the TAM.

[0101] S304: Receive heartbeat information sent by the TAM at preset time intervals through the TCP connection of the 3G channel.

[0102] Wherein, the preset time may be 30s, which is not limited in this application and may be selected according to specific circumstances. The mobile terminal maintains the activity of the TCP connection of the 3G channel by receiving the heartbeat information regularly sent by the TAM:

[0103] Receive...

Embodiment 3

[0165] Such as Figure 9 as shown, Figure 9 It is a flowchart of a method for constructing a dual-channel hybrid tunnel for a mobile terminal provided in Embodiment 3 of the present application. This method is the operation process of the TAM side when the virtual tunnel connection enables two physical channels, including:

[0166] S601: Establish a TCP connection with the 3G channel between the mobile terminal.

[0167] Specifically, after the computer on the TAM side is installed to start the software, the two ports 45654 and 45655 of the network interface will be opened as the server side of the Socket connection, and the new TCP connection request sent by the mobile terminal through the 3G channel and the Wi-Fi channel will be monitored. .

[0168] When port 45654 of the TAM side detects the Socket request sent by the newly accessed mobile terminal, it returns a confirmation message to the 3G channel of the mobile terminal, and the TCP connection of the 3G channel is e...

Abstract

The invention provides a construction method for the two-channel hybrid tunnel of mobile terminals. The construction method comprises the following steps: distributing the request information of a tunnel connecting IP address to a TAM sending request through pre-established TCP connection of a 3G channel with a TAM, and receiving the tunnel connecting IP address distributed by the TAM according to the request information; when a Wi-Fi signal verified by a wireless router is detected, establishing the TCP connection of a Wi-Fi channel with the TAM, and obtaining the amount of the mobile terminals connected with the TAM to establish the Wi-Fi channel; calculating the distribution ratio of data packets in the 3G channel and the Wi-Fi channel according to the channel parameters of the two channels and the amount of the mobile terminals, and storing and sending the distribution ratio to the TAM. A tunnel for using two physical channels to transmit data is established between the mobile terminals and the TAM, data transmission in the 3G channel is guaranteed all the time, and data transmission can be carried out at the same time in the Wi-Fi channel, so that the access bandwidths of the mobile terminals are improved, and data transmission delay caused by the switching of the channels is avoided.

Description

technical field [0001] The present application relates to the field of wireless network communication, and more specifically relates to a method for constructing a dual-channel hybrid tunnel for a mobile terminal. Background technique [0002] With the rapid development of modern communication technology, there are more and more communication methods between devices. Wireless interfaces represented by Wi-Fi, 3G / 4G, WiMax, ZigBee, Bluetooth, UWB (Ultra Wideband, pulse radio) Access technology is widely used in various types of mobile terminals. Among them, the wireless access technologies used by mobile terminals represented by mobile phones mainly include Wi-Fi and 3G / 4G. [0003] At present, when a mobile terminal such as a mobile phone is located in an area covered by two signals at the same time, generally only one of the access technologies is selected for data communication. However, this way of using only one channel for network access in a multi-signal coverage area...
