Abstract

The embodiment of the invention discloses a method and related equipment for switching from a WiMAX access network to a WiFi access network. Wherein, the method includes: receiving an access network switching request message sent by the terminal through the WiMAX access network; maintaining the current service connection of the terminal in the WiMAX core network; sending an access network switching request message to the terminal through the WiMAX access network Responding to a message, so that the terminal switches radio frequencies and performs network access through the WiFi access network; receives an address binding update message of the terminal sent by the WiFi access network, and the address binding update message includes the The first address of the terminal when the terminal accesses through the WiFi access network; switching the current service connection of the terminal to the first address. Through the embodiment of the present invention, the service continuity in the process of switching from WiMAX to WiFi in 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 WiMAX access network to a WiFi 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, Microwave Access Global Interoperability) is also a wireless broadband access technology. There are many operators in the world using 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...

Examples

Embodiment 1

[0025] see figure 1 , which is a flowchart of an embodiment of a method for access network handover in the present invention, the method includes the following steps:

[0026] Step 101: receiving an access network switching request message sent by the terminal through the WiMAX access network;

[0027] Step 102: maintaining the current service connection of the terminal in the WiMAX core network;

[0028] Step 103: Send an access network switching response message to the terminal through the WiMAX access network, so that the terminal switches the radio frequency and performs network access through the WiFi access network.

[0029] Step 104: Receive an address binding update message of the terminal sent by the WiFi access network, where the address binding update message includes the first address of the terminal when the terminal accesses through the WiFi access network ;

[0030] Step 105: Switch the current service connection of the terminal to the first address.

Embodiment 2

[0047] see figure 2 , which is a signaling flow chart of another embodiment of a method for access network switching in the present invention. This embodiment is an interaction process of various control signaling when a WiMAX access network is switched to a WiFi access network. The method specifically Include the following steps:

[0048] Step 201: When the terminal determines that handover is required, it sends a reverse access network handover request message to the single radio frequency handover server located in the WiMAX core network through the WiMAX access network;

[0049] Among them, the terminal can automatically decide to switch to the WiFi network when it finds that the WiMAX 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 the handover process.

[0050] The access ne...
