Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to a determination".

[0029] Next, the embodiments of this specification will be described in detail.

[0030] The following combines Figure 1 to describe the application scenarios of the grouping method and device of the AP in the embodiments of this specification. It should be noted that Figure 1 The examples shown are only examples of the application scenarios to which the embodiments of this specification can be applied to help those skilled in the art understand the technical content of this specification, but it does not mean that the embodiments of this specification cannot be used in other devices, systems, environments or scenarios.

[0031] Figure 1 is a schematic diagram of an application scenario shown according to an exemplary embodiment of this specification.

[0032] As Figure 1 shown, this application scenario may include devices such as an AC (Access Controller), an AP (Access Point), a DHCP (Dynamic Host Configuration Protocol Server) server, a DHCP snooping device, and a switch.

[0033] The AC can be used to perform service configuration and management on the AP.

[0034] The AP can be used to provide wireless network access services for clients (such as mobile phones, laptops, etc.).

[0035] The DHCP server can be used to automatically assign IP addresses and other network configurations, such as subnet masks, default gateways, DNS servers, etc., to DHCP clients.

[0036] A DHCP Snooping device can be used to monitor DHCP packets, verify their legality, filter illegal DHCP packets, so as to block illegal DHCP servers in the access network. The DHCP Snooping device can include, for example, a switch or a router, etc.

[0037] A switch can be a network device for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes accessing the switch. Exemplarily, the switch can be a POE (Power Over Ethernet) switch, that is, a switch supporting Ethernet power supply.

[0038] In this embodiment, each switch can include at least one AP, for example, it can include AP1, …… APn, where n is a positive integer. The AP can be used as a DHCP client.

[0039] According to the embodiments of this specification, the APs managed by the AC can be distributed at multiple locations. The APs at the same location are required to have the same configuration, and the APs at different locations are required to have different configurations. Since the number of APs is large, the AC can divide the APs at these multiple locations into multiple different AP groups and then perform unified configuration. Each location can correspond to an AP group.

[0040] Exemplarily, in this embodiment, the APs managed by the AC can be distributed at two locations, namely Region 1 and Region 2. The APs at these two locations can be assigned IP addresses by the same DHCP server, and the assigned IP addresses are in the same network segment. The APs in each location can access the Internet, obtain IP addresses, and be managed by the AC through a multi-level layer-2 switch. The switch adjacent to the AP can be responsible for power supply. The top-layer switch can not only converge but also play the role of DHCP snooping. The APs in Region 1 and Region 2 access the DHCP snooping device and communicate with the DHCP server through the DHCP snooping device to obtain IP addresses.

[0041] In the related art, when grouping APs, each AP needs to be configured one by one, and the network planning cost on the AC is relatively high. According to the AP grouping method of the embodiments of this specification, the requirement of dividing APs with the same network segment but at different locations into different groups is realized, and there is no need to configure them one by one, reducing the network planning cost on the AC.

[0042] The following will elaborate on the AP grouping method provided by the embodiments of this specification. As Figure 2 shown, Figure 2It is a flowchart of a grouping method for an AP shown in this specification according to an exemplary embodiment. The grouping method for an AP provided in the embodiments of this specification may include the following steps.

[0043] In step S201, the AP sends an IP address acquisition request to the DHCP server.

[0044] According to the embodiments of this specification, the IP address acquisition request can be used to request the DHCP server to allocate an IP address.

[0045] In step S202, the DHCP server receives the IP address acquisition request sent by the AP.

[0046] In step S203, the DHCP server allocates an IP address to the AP according to the IP address acquisition request.

[0047] According to the embodiments of this specification, the DHCP server can be configured with an IP address pool. After receiving the IP address acquisition request, the DHCP server can select an IP address from the IP address pool and allocate it to the AP. Optionally, the DHCP server can allocate IP addresses in the same network segment to different APs.

[0048] Optionally, in addition to the IP address, the DHCP server can also allocate other network configuration information to the AP, such as the gateway, subnet mask, DNS, etc.

[0049] In step S204, the DHCP snooping device sends a raw offer message to the AP via the DHCP snooping device, and the raw offer message includes the IP address.

[0050] According to the embodiments of this specification, the raw offer message is an offer message sent by the DHCP snooping device. The offer message can be used to notify the AP of the allocated IP address. Optionally, in addition to the IP address, the offer message can also include other network configuration information allocated to the AP, such as the gateway, subnet mask, DNS (Domain Name Server), etc.

[0051] In step S205, the DHCP snooping device intercepts the raw offer message sent by the DHCP server to the AP.

[0052] According to the embodiments of this specification, the DHCP snooping device can listen to the DHCP messages sent by the DHCP server. When it listens to the raw offer message sent by the DHCP server to the AP, it intercepts the raw offer message.

[0053] In step S206, the DHCP snooping device fills in the location information in the original offer message to obtain a target offer message.

[0054] According to the embodiments of this specification, the location information may represent the location of the AP. The location information can be user-defined or carry the MAC (Media Access Control) address of the AP or the DHCP snooping device as the location information.

[0055] In step S207, the DHCP snooping device sends the target offer message to the AP.

[0056] In step S208, the AP receives the target offer message sent by the DHCP snooping device.

[0057] According to the embodiments of this specification, the target offer message includes the location information and the IP address assigned by the DHCP server to the AP. The AP can obtain the location information and the IP address assigned by the DHCP server to the AP according to the target offer message.

[0058] In step S209, the AP sends a tunnel connection request to the AC according to the IP address, and the tunnel connection request includes the location information.

[0059] In step S210, the AC receives the tunnel connection request sent by the AP.

[0060] In step S211, the AC establishes a tunnel with the AP according to the tunnel connection request and divides the AP into an AP group corresponding to the location information.

[0061] According to the embodiments of this specification, the DHCP server can divide APs with the same location into the same AP group according to the location information.

[0062] According to the method for grouping APs in the embodiments of this specification, the requirement of dividing APs with different locations but the same network segment into different groups according to their locations is realized, and there is no need for one-by-one configuration, reducing the network planning cost on the AC.

[0063] Optionally, the original offer message contains an Option (option) field. Based on this, the DHCP snooping device can, for example, fill in the location information into the Option field of the original offer message.

[0064] For example, according to the definition in RFC2132, Options 128 to 254 in the DHCP packet are reserved fields and can be used for custom purposes. Based on this, any one or more fields among Options 128 to 254 can be selected to carry location information. Exemplarily, in this embodiment, Option182 is used to carry address information. The DHCP snooping device fills the location information in Option 182 of the original offer packet to obtain the target offer packet. The AP extracts the address information in Option 182 from the received target offer packet,

[0065] Optionally, the tunnel connection request can be based on the CAPWAP protocol. The AP can establish a CAPWAP tunnel with the AC through the tunnel connection request. The CAPWAP protocol packet contains a location definition field. Based on this, during the process of the AP establishing a CAPWAP tunnel with the AC, the location information can be carried in the location definition field of the tunnel connection request and passed to the AC.

[0066] Corresponding to the embodiments of the foregoing method, this specification also provides embodiments of a packet device of the AP and a terminal to which it is applied.
