Embodiment 1

[0053] An embodiment of the present invention provides a method for allocating IP addresses. The execution subject of this method is a gateway, and the AC (Access Controller, access controller) function module and the DHCP function module are integrated on the gateway, and the gateway can automatically realize the configuration process of the DHCP service side through the method provided by the embodiment of the present invention, namely Realize the automatic configuration of the corresponding relationship between the VLAN ID and the address pool, and implement the allocation of IP addresses for users accessing the wireless network according to the configured corresponding relationship.

[0054] see figure 1 , the method specifically includes the following steps:

[0055] Step 101: Configure a gateway interface and a DHCP address pool for the network segment.

[0056] Usually, users under one SSID (Service Set Identifier) ​​belong to one network segment, and the gateway conf...

Embodiment 2

[0092] see figure 2 An embodiment of the present invention provides a gateway for allocating IP addresses, and the gateway is used to implement the method for allocating IP addresses provided in Embodiment 1 above. Specifically, the gateway includes:

[0093] The configuration module 201 is used to configure the gateway interface and the dynamic host allocation protocol DHCP address pool for the network segment; configure the virtual local area network (VLAN) two-level architecture for the gateway interface;

[0094] Establishment module 202, is used for according to DHCP address pool and VLAN two-level structure, establishes the corresponding relationship of VLAN mark and address pool;

[0095] The assignment module 203 is configured to receive wireless user packets, and allocate network interconnection protocol IP addresses to users corresponding to the wireless user packets according to the correspondence between the wireless user packets and the VLAN identifiers and addr...

Abstract

The invention provides a method and gateway for distributing IP addresses. The method comprises the steps that a gateway interface and a dynamic host configuration protocol DHCP address pool are configured for a network segment; a virtual local area network (VLAN) two-stage framework is configured for the gateway interface; according to the DHCP address pool and the VLAN two-stage framework, a corresponding relation between the VLAN identifier and the address pool is built; a wireless user message is received, an IP address is distributed for a user corresponding to the wireless user message according to the wireless user message and the corresponding relation between the VLAN identifier and the address pool. The functions of a DHCP server are integrated to the gateway, the corresponding relation between the VLAN identifier and the address pool is automatically configured for the gateway, the IP address is distributed for the user according to the corresponding relation, manual intervention in the distribution process is avoided, the configuration and maintenance in the distributing process are easy, and the method and gateway can be applied to large-scale wireless network deployment in the operator level.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular, to a method for allocating IP addresses and a gateway. Background technique [0002] Currently, a user often accesses a wireless network through a user terminal to surf the Internet wirelessly. When a user surfs the Internet wirelessly, an IP (Internet Protocol, Internet Protocol) address needs to be allocated to the user terminal, so that the user terminal performs wireless network communication according to the allocated IP address. [0003] At present, technicians need to configure VLAN ID (Virtual Local Area Network Identity, virtual local area network identification) and switch port number in wireless AP (Wireless Access Point, wireless access point) in advance, and in advance in DHCP (Dynamic Host Configuration Protocol, dynamic Configure the mapping relationship between VLAN ID, switch port number and IP address on the host allocation protocol) server...
