Embodiment approach

[0024] In one embodiment, we can define the identification information of the second physical network connected to a certain port of the network access device far away from the router through "the management IP address of the network access device + the port number".

[0025] In another embodiment, the network management system can pre-configure all network access device IDs under the port of the routing device. We use "network access device ID + port number" to define the Identification information of the second physical network connected to a certain port of the device.

[0026] Of course, combine Figure 2A We need to recognize that there may be an intermediate network access device 22A in the fixed communication network between the routing device 21 and the network access device 22B directly connected to the user networks U2, U3, if the last network access device 22B does not With a globally addressable network device ID, the network access devices 22A and 22B between the...

Abstract

The invention provides a physics network identification information announcement method in a fixed communication network system. The fixed communication network system comprises a route device, a plurality of network access devices, and user network connected with the network access devices. The method comprises: the step a) the network access devices receive and identify protocol information from a direction of the route device; b) the network access devices insert one physics network identification information into the protocol information and transmit toward the network at the lower part of the corresponding port, wherein the physics network identification information stands for unique addessable information of the network on the lower part of the port in the device range. The invention solves the problems of service switch when the mobile terminal roams to the fixed communication network, and physics network positioning of the user terminal in the fixed communication network, and micro-mobility management.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a communication device for notifying physical network identification information in a fixed communication network. Background technique [0002] With the rapid development of network communication technology, fixed-mobile convergence has received more and more attention. For example, when a mobile terminal is outdoors, it can pass through its mobile interface, typically such as WiMAX (Worldwide Interoperability for Microwave Access) interface, or 3G ( The third-generation mobile communication) interface accesses its corresponding wireless communication network to enjoy the service; we know that in the WiMAX access network, its base station (BS) passes the DL-MAP message of its downlink broadcast channel to the BSID (base station identification code) Broadcasting, the mobile terminal detects and scans the information of adjacent base stations, and decides to re...
