Abstract

The invention provides a method and a device for supplying mobile access by a wireless fidelity (WiFi) network in a fixed access network. Network access equipment marks the network access position information of a WiFi access point corresponding to the fixed access network, which is accessed at a user port; the WiFi access point obtains the network access position information and informs the network access position information in a WiFi network service range of the WiFi access point; and a WiFi mobile communication terminal obtains the network access position information to access or switch the network. The invention can support the rapid network discovery and the mobile switch operation of the WiFi mobile communication terminal in the fixed access network.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for providing mobile access through a WiFi network in a fixed access network and a corresponding device and system. Background technique [0002] WiFi (Wireless Fidelity: Wireless High Fidelity) is a wireless communication protocol that adopts the 802.11a / b / g standard. Its biggest advantage is its high transmission speed, which can reach 54Mbps. It is a short-distance Wireless Communication Technology. [0003] In the current mainstream fixed access network, a customer premise network (CPN: CustomerPremises Network) is connected to the second / third layer access equipment in the fixed access network through its customer premise gateway (for example: DSL modem / router, etc.), Typical access means such as: DSL (Digital Subscriber Line), PON (Passive Optical Network), LAN (Local Area Network) and other access means, and in the CPN network, a wireless acc...
