Embodiment 1

[0057] In the future smart home, multiple access point devices are deployed in the home. These access point devices are connected to IoT devices such as sensors, home appliances, and smart lights, and are also connected to entertainment or work devices such as smartphones, tablets, and notebooks. In this scenario, multiple access point devices are connected to each other in a tree structure (north-south connection, east-west connection not) or mesh structure (north-south connection, east-west connection).

[0058] In this embodiment, multiple access point devices such as image 3 The deployment shown is in a home. In this embodiment, the access point device refers to a device with an access point function, and these access point devices are respectively access point device 1, access point device 2, access point device 3, ..., access point device Entry point device n. These access point devices form a multi-access point set. Each access point device can obtain information ab...

Embodiment 2

[0073] In an enterprise network, multiple access point devices are deployed in the enterprise, and these access point devices form a network to provide network connection services for employees and devices of the enterprise. Such as Figure 4 As shown, an architecture for deploying multiple access point devices is described. This architecture is a tree architecture. In addition, the architecture composed of multiple access point devices may also be a mesh architecture. exist Figure 4 In , multiple access point devices refer to devices with access point functions, and there may be modules with other functions in the multiple access point devices.

[0074] exist Figure 4 In, the architecture of 4 access point devices is described. Access point devices 1 and 2 have the function of AP and the function of Ethernet port. Access point device 1 and access point device 2 are connected through Ethernet port. STA1 is connected with the AP function of access point device 1 . STA2 ...

Embodiment 3

[0093] In a smart building, multiple access point devices are deployed in the building, and these access point devices provide network connection services for smart electricity meters, water meters, video surveillance equipment, sensors, home appliances, and home entertainment devices in the building.

[0094] Multiple access point devices are connected to each other in a tree structure (north-south connection, east-west connection not) or mesh structure (north-south connection, east-west connection).

[0095] Multiple access point devices such as Figure 5 The shown deployment is in a home, and the access point devices refer to devices with access point functions, and these access point devices are respectively access point device 1, access point device 2, access point device 3, ... Entry point device n.

[0096] These access point devices may work in different frequency bands, for example, there are three frequency bands commonly used by WLAN devices at present: 2.4GHz, 5GH...

Abstract

The invention provides a multi-access-point auxiliary transmission method and device. The multi-access-point auxiliary transmission method comprises the steps that: a second access point receives databelonging to a first station from a first access point, wherein the second access point and the first access point belong to the same multi-access-point set; and the second access point sends the data belonging to the first station associated with the first access point to the first station. According to the multi-access-point auxiliary transmission method and the device, the access points in theplurality of access point sets can realize auxiliary transmission without complex cooperation, so that the access efficiency of the station is improved, and the transmission delay of the downlink service is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-access point assisted transmission method and device. Background technique [0002] In a wireless local area network, an access point (AP for short) and multiple non-AP Stations (STA for short) associated with the AP form a basic service set (basic service set, short for short). BSS). After the station and the access point complete the association, key negotiation and other operations, the station and the access point perform data transmission. [0003] A station can only be associated with one access point at a time, such as figure 1 shown. AP1 and STA form a basic service set for communication. When STA wants to transmit data with AP2, it needs to disconnect from AP1 first, and then establish a connection with AP2. [0004] With the explosive growth of the WLAN network, the network load is also increasing, the deployment of the WLAN network is becoming more and mo...
