Problems solved by technology

However, since the coverages of the access points deployed in the network may overlap with each other, the GAS query request message sent by such a station may be received by multiple access points. When these access points forward the GAS query request message according to the After querying the content of the request, the same content will be repeatedly transmitted between the server and the site, thus wasting resources for transmitting information between the site and the server

Embodiment 1

[0168] Provide a service query method, which can be mainly applied to such as Figure 1a and 1b In the service query system shown, in Figure 1a The system shown includes a site, multiple access points, and service nodes. Multiple sites can be connected to one access point, and multiple access points can be connected to one service node. Multiple access points and service nodes are deployed on on different physical devices. Among them, the service node can provide the function of service query, and can query the current network or various services that can be provided through the current network, such as Internet access service, printer service, etc. The specific service provided may be the device where the service node is located. Other specialized equipment is also possible. For example, the Internet service can be provided by the device where the service node is located, and the printer service can be provided by a dedicated printer in the network.

Embodiment 2

[0191] Provide a service query method, which can be mainly applied to the above Figure 1a and 1b In the service query system shown, the method of this embodiment is the method executed by the site in the system, and the method of this embodiment is different from the first embodiment above, in this embodiment, the method on the side of the site is used to reduce the The data transmitted between the station through the access point and the service node, and the method in the first embodiment above is to reduce the data transmitted between the station through the access point and the service node through the method of the network side (service node), the flow chart is as follows Figure 4 shown, including:

[0192] Step 201, receiving connection information sent by an access point, where the connection information includes a service node identifier.

[0193] It can be understood that during the process of a station discovering an access point, the station may receive a beacon ...

Embodiment 3

[0205] Provide a service query method, which can be mainly applied to the above Figure 1a and 1b In the service query system shown, the method in this embodiment is a method executed by an access point in the system, and the flow chart is as follows Figure 5 shown, including:

[0206] In step 301, a first service query request message is sent to the service node, and the first service query request message includes a site identifier and service information to be queried.

[0207] It can be understood that when a station needs to initiate a query process for the service information of a certain service node, it can send a query request message to the access point, and the query request message can include the station identifier and the service information requested to be queried; the access point The site identifier and the service information requested to be queried may be extracted and added to the first service query request message and sent to the service node, and then ...

Abstract

The embodiment of the invention discloses a service query method, device, system and site, which are applied in the technical field of communication. After receiving the first service query request message sent by multiple access points, the service node includes the station identifier and the service information requested to be queried, and only sends the query result information to one or more of the access points, that is, the first access point The corresponding station is identified by sending to the above station, and instruction information is sent to other access points to instruct other access points not to send query result information. In this way, after the service node receives a service query request message for the same service information from the same site, the service node will not repeatedly send the query result information to all access points to reply to the site, but select one or more access points Click to reply the query result information to the site, thereby reducing the data transmitted between the site through the access point and the service node, and saving transmission resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a service query method, device, system and site. Background technique [0002] Wireless Fidelity (Wireless Fidelity, WiFi) technology is widely used in many electronic devices such as laptops, tablets, and mobile phones. Its network structure is the type with infrastructure (infrastructure) and the type of peer-to-peer network connection. Commonly used is the type with infrastructure. [0003] There are access points (Access Point, AP), stations (Station, STA) and servers in the WiFi network structure with infrastructure type. Multiple stations can connect to the access point and use the services provided by the access point, such as network connection, etc. Generally, the access point mainly provides services at the WiFi level, and the access point may also provide services such as network and upper-layer applications. [0004] When a station searches for an access point...
