Problems solved by technology

However, for WiMAX and WiFi dual-mode terminals, for the frequency spectrum used by most WiMAX networks actually deployed, when the WiMAX radio frequency circuit and the WiFi radio frequency circuit work at the same time, they will cause greater interference to each other. Therefore, in fact, WiMAX , WiFi dual radio frequency working mode has great difficulties in specific application, whether it can effectively solve the interference problem has no definite answer

Embodiment 1

[0023] see figure 1 , which is a flowchart of an embodiment of a method for switching from a WiFi access network to a WiMAX access network in the present invention, the method includes the following steps:

[0024] Step 101: receiving an access network switching request message sent by a terminal;

[0025] Step 102: maintaining the current service connection of the terminal in the WiMAX core network;

[0026] Step 103: Send an access network switching response message to the terminal through the WiFi access network, so that the terminal switches the radio frequency and performs network access through the WiMAX access network;

[0027] Step 104: Receive an address binding update message of the terminal sent by the WiMAX access network, where the address binding update message includes the first address of the terminal when the terminal accesses through the WiMAX access network ;

[0028] Step 105: Switch the current service connection of the terminal to the first address.

Embodiment 2

[0054] see figure 2 , which is a signaling flow chart of another embodiment of a method for switching from a WiFi access network to a WiMAX access network in the present invention. This embodiment is a flow chart of each control signaling when the WiFi access network is switched to a WiMAX access network An interactive process, the method specifically includes the following steps:

[0055] Step 201: When the terminal determines that handover is required, it sends an access network handover request message to the single radio frequency handover server located in the WiMAX core network through the WiFi access network;

[0056] Among them, the terminal can automatically decide to switch to the WiMAX network when it finds that the WiFi signal is poor, or it can be determined by the user to switch to the WiMAX network, or it can be determined by the network side that it needs to switch, and then the terminal sends an access network switch A request message, requesting to start th...

Embodiment 3

[0102] Corresponding to the above method for switching from a WiFi access network to a WiMAX access network, an embodiment of the present invention further provides an apparatus for switching from a WiFi access network to a WiMAX access network. see Figure 5 , which is a structural diagram of an embodiment of a device for switching from a WiFi access network to a WiMAX access network in the present invention, and the device includes: a switching request receiving unit 501 and a switching request sending unit 502 . The internal structure and connection relationship of the device will be further introduced below in conjunction with the working principle of the device.

[0103] A handover request receiving unit 501, configured to receive an access network handover request message sent by the terminal through the WiFi access network;

[0104] A connection request sending unit 502, configured to send a keep connection request message to a corresponding data forwarding entity, so ...

Abstract

The embodiment of the invention discloses a method for switching a WiFi access network to a WiMAX access network and related equipment, wherein the method comprises the following steps: receiving an access network switching request message sent by a terminal through the WiFi access network; maintaining current service connection of the terminal in a WiMAX core network; sending an access network switching response message to the terminal by the WiFi access network so that the terminal switches a radio frequency and carries out network access by the WiMAX access network; receiving an address binding updating message of the terminal, which is sent by the WiMAX access network and comprises a first address of the terminal when the terminal accesses by the WiMAX access network; and switching the current service connection of the terminal to the first address. According to the embodiment of the invention, the service continuity in the process of switching from the WiFi access network to the WiMAX access network in a single radio frequency mode can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for switching from a WiFi access network to a WiMAX access network and related equipment. Background technique [0002] WiFi (Wireless Fidelity, Wireless Fidelity) is an important wireless local area network technology, and is also a wireless broadband access technology. At present, there are a large number of WiFi hotspots in operation around the world, providing free or paid wireless Internet access services. WiMAX (Worldwide Interoperability for Microwave Access) is also a wireless broadband access technology. Many operators around the world use WiMAX technology to build wireless broadband access networks. [0003] Both WiFi and WiMAX are important wireless broadband access technologies, and each has its own advantages and disadvantages. Among them, WiFi network deployment is fast, low in cost, high in bandwidth, and does not require authorization to ...
