Design method of VLAN function in wireless communication system

Abstract

The invention provides a design method of a VLAN function in a wireless communication system, which comprises the following steps: a. a unique logical group number for a whole network is allocated to each virtual workgroup, and when an exchanger carries out VLAN planning, a VLAN ID is assigned to each logical group number, and VLAN IDs corresponding to identical logical group number in all exchangers are intercommunicated in a routing mode simultaneously; b. when base station initialization starts, a corresponding relation table of the logical group number of the superior exchanger and the VLAN ID is stored in an internal memory of the base station, when a terminal starts up to initiate registration, the base station obtains the logical group number of the terminal and stores the logical group number in the internal memory of the base station; and c. when the terminal initiates an uplink service, the base station inquires the corresponding relation table to obtain the VLAN ID corresponding to the logical group number of the terminal, an 802.1Q label is inserted into a packet and sent to the exchanger, and when the base station receives the packet, the 802.1Q label is removed if OX8100 exists, and is sent to the corresponding terminal. The method has simple configuration, and the VLAN planning of each exchanger can be carried out independently, so the flexibility of network design is enhanced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a design method of a VLAN function in a wireless communication system. Background technique [0002] Virtual Local Area Network (VLAN) is a technology that logically rather than physically divides network resources and network users into multiple small logical networks. Using VLAN can establish a virtual working group, each user in the group is like in the same local area network, and users who are not in this group cannot access the members of this group. The technology of VLAN is generally applied in switches and is implemented based on VLAN marking. At present, the marking method of the 802.1Q standard proposed by IEEE is the most widely used. Such as figure 1 As shown, there is a 4-byte 802.1Q tag in the IEEE 802.1Q frame structure, which includes a 2-byte TPID (Tag Protocol Identifier) ​​and a 2-byte TCI (Tag Control Information). The TPID value is 0X8100, indicating...

AI Technical Summary

Problems solved by technology

In addition, if all switches in the entire network adopt a unified VLAN plan, although the aforementioned problems can be avoided, the flexibility of network design is greatly reduced, and the possibility of errors caused by inconsistent VLAN data configuration increases.
