Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0046] For multi-mode user equipment working in single radio mode and supporting WiMAX and WiFi, when switching between WiFi and WiMAX working modes, the CoA (Care of Address, care of address) of the user equipment will be updated, and the data flow will change. path. In order to ensure the reliability of the data service, an embodiment of the present invention provides a single radio frequency user equipment handover method. During the user equipment handover process, the target access network FA (Foreign Agent, external agent) or the source access network FA caches user data, After the user equipment completes the network access of the new network, the target access network or the source access network sends t...

Abstract

The invention discloses a method and equipment for guaranteeing the integrity of switching data of single radio frequency user equipment, relating to the technical field of communications. In the method, mobile IP registration is carried out to a home agent of a core network after an object access network foreign agent and a source access network foreign agent exchange information through a mobile IP session; the object access network foreign agent caches user data sent by the home agent to the user equipment after registration is completed; and the object access network foreign agent sends the cached user data to the user equipment according to a request of the user equipment after the user equipment completes the access of an object access network and carries out the mobile IP registration. The lossless switching of the single radio frequency user equipment between the WiMAX access network and the WLAN access network can be realized by the method, and the reliability of data service is guaranteed.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and equipment for ensuring data integrity of user equipment single radio frequency handover. Background technique [0002] WiFi (Wireless Fidelity, wireless fidelity) is an important wireless local area network technology, and is also used for wireless broadband access. At present, there are a large number of WiFi hotspots in operation around the world, providing free or paid wireless Internet access services. [0003] WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband access technology and one of the international standards for third-generation wireless communication technologies. Many operators around the world use WiMAX technology to build wireless broadband access networks . [0004] Both WiFi and WiMAX are important wireless broadband access technologies with their own advantages and disadvantages. WiFi network deployment is fast, lo...
