Background

To improve access rates and throughput of wireless local area network (Wireless Local Area Network, WLAN) technologies such as wireless fidelity (Wireless Fidelity, wi-Fi), IEEE802.11 has established IEEE802.11be to study the next generation mainstream (802.11 a/b/g/n/ac/ax) Wi-Fi technologies.

In the next generation mainstream ieee802.11be, multiple connection transmission is adopted between an Access Point (AP) and a Station (STA), so as to improve throughput of the whole system (data of different contents is transmitted in each frequency band), and improve success rate of data transmission/reception (data of uniform contents is transmitted in each frequency band).

To further increase the throughput of the system, there may be devices in 802.11be that support simultaneous transmission and reception (reception and transmission do not interfere with each other under multiple connections), some devices may support only multiple connection transmission or reception, and some devices may support only single connection reception or transmission.

In the related art, two methods for a station to initially access to a network are: 1. transmitting a probe request (probe request) frame under the same connection, and receiving a probe response (probe response frame) fed back by the AP; 2. listening for beacon (beacon) frames broadcast by the AP and then sending association request (association request) frames.

However, in the related art, when devices in the access network are initially accessed, the devices such as 802.11be establish an initial connection on a connection at 2.4GHz or 5GHz, and if each station attempts to establish the access network on the connection or due to the existence of a hidden node, the probability of occurrence of collision is high.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The initial access method provided by the embodiment of the disclosure is applied to a wireless local area network communication system comprising a data sending device and a data receiving device. The data transmitting device and the data receiving device may be a Station (STA) or an Access Point (AP). The data transmitting device and the data receiving device perform forward transmission and return transmission of data through the wireless local area network.

The STA referred to in the present disclosure may be understood as a User Terminal in a wireless local area network, where the User Terminal may be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., and is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device, an in-vehicle device, etc. having a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a palm top, a personal digital assistant (Personal Digital Assistant, PDA), a notebook, a tablet, a wearable device, an internet of things (Internet of Things, ioT) client, or an in-vehicle device, etc.

The AP referred to in this disclosure refers to a device, router, etc. of a wireless local area network user terminal accessing a network.

In the related art, data frame transmission is performed between an STA and an AP using the IEEE802.11 standard. Currently, IEEE802.11 is established as IEEE802.11be to study the next generation mainstream Wi-Fi technology, and the studied range is: bandwidth transmission at 320MHz, aggregation and coordination of multiple frequency bands, etc., the proposed perspective increases the rate and throughput by at least four times over the existing ieee802.11 ax. The main application scenes are video transmission, AR, VR and the like.

The aggregation and collaboration of multiple frequency bands means that multiple bandwidths in multiple frequency bands or the same frequency band are communicated at the same time, for example, communication is performed at three frequency bands of 2.4GHz, 5GHz and 6-7GHz at the same time. Simultaneous communication in multiple frequency bands or multiple bandwidths in the same frequency band may be understood as Multi-connection communication or as Multi-link aggregation (MLA). The multi-connection communication can improve throughput of the entire system (data of different contents is transmitted in each frequency band) and can improve success rate of data transmission/reception (data of uniform contents is transmitted in each frequency band).

In the related art, the establishment of an initial connection by a station is accomplished by means of resource contention, for example, an 802.11be device establishes an initial connection on a connection at 2.4GHz or 5GHz, for example, each station attempts to establish a connection to the access network on the connection or because of the existence of a hidden node, so that the probability of occurrence of collision is high.

In order to reduce the probability of communication collision of the 802.11be in the initial connection process, the process of initial access under multiple connections between devices is limited in the embodiment of the disclosure, and different message frames of the initial access network request are sent on different connections.

Fig. 1 is a flowchart illustrating an initial access method according to an exemplary embodiment, which is used in a station as shown in fig. 1, and includes the following steps.

In step S11, a first message frame of the network access request is sent at the first connection, where the first message frame includes a capability information value supported by the station.

In the embodiment of the disclosure, the first message frame of the network access request may be an association request frame (association request) or a probe request frame (probe request). Wherein the station transmits association request upon listening to beacon (beacon) frames broadcast by the AP. The station transmits a probe request without hearing a beacon frame broadcast by the AP.

The first connection in the embodiment of the present disclosure may be a connection that the station receives a beacon frame broadcast by the AP.

The capability information value supported by the station may be to support simultaneous transmission and reception under multiple connections or to support simultaneous transmission or reception under multiple connections.

In step S12, the indication information sent by the AP is received. The indication information is used to indicate a second connection determined from the capability information value.

In the embodiment of the disclosure, after receiving the first message frame, the AP analyzes the capability information value in the first message frame, and further determines multiple connections supported by the station according to the capability information value, and determines other connections suitable for the station to perform initial network access and different from the first connection, which are hereinafter referred to as second connection. Wherein the first connection is different from the second connection. The AP transmits indication information to the station, the indication information indicating the second connection determined according to the capability information value. And the station receives the indication information sent by the AP.

In step S13, the second message frame of the network access request is transferred to the second connection according to the capability information value and the indication information.

In the embodiment of the disclosure, the first message frame sent by the station on the first connection includes the capability information value supported by the station, receives the indication information, and converts to the second message frame of the network access request sent by the second connection according to the capability information value and the indication information, so that the occurrence probability of communication conflict in the initial network access process can be reduced.

In the embodiment of the disclosure, the station may also listen to the beacon frame broadcast by the AP under any connection.

Fig. 2 is a flow chart illustrating an initial access method, as shown in fig. 2, for use in a station, according to an exemplary embodiment, including the following steps.

In step S21, the beacon frame broadcast by the AP is intercepted under any connection.

The beacon frame includes an AP-supported connection, a basic service set (Basic Service Set, BSS) load (load) under the AP-supported connection, and a BSS average access delay (Access delay average). The beacon frame may also include other information related to the connection.

The station transmits association request upon listening to beacon frames broadcast by the AP. The station sends a probe request without hearing the beacon frame broadcast by the AP.

In step S22, a first message frame is sent on the first connection.

Wherein, if the station hears the beacon frame, the first message frame is association request. association request includes capability information values for site support. If no beacon frame is detected, the first message frame is a probequest. The probe request includes a capability information value supported by the site.

The first connection may be a connection that receives an AP broadcast beacon frame. That is, the station transmits association request frames on a connection that receives an AP broadcast beacon frame. The station includes a capability information value supported by the station in association request frames, for example, the capability information value may be a capability to support simultaneous transmission and reception under multiple connections or a capability to support simultaneous transmission or reception under multiple connections.

In step S23, the indication information sent by the AP is received. The indication information is used to indicate a second connection determined according to the capability information value, BSS load, and BSS Access delay average.

In the embodiment of the disclosure, the AP switches the station to other execution procedures for initial connection under other connections according to BSS load and BSS Access delay average under each connection and capability information values supported by the station. For example, if the BSS load in the second connection is smaller than the BSS load in the first connection and the value of BSS Access Delay in the second connection is smaller than the value of BSS Access Delay in the first connection, the second connection is selected to transmit the second message frame.

In the embodiment of the disclosure, the terminal may receive the indication information sent by the AP based on association response or probe response.

In step S24, the method switches to one or more second message frames for the second connection to send a network access request according to the capability information value and the indication information.

In one implementation of the embodiment of the disclosure, the number of the second message frames may be one or more.

If the first message frame is association request, the second message frame may be an authentication request frame (authentication request) or a dynamic host configuration protocol (Dynamic Host configuration Protocol, DHCP) request frame. If the first message frame is a probe request, the second message frame may be association request, authentication request, DHCP request, etc.

In an embodiment of the present disclosure, the second connection comprises a plurality of different connections. When the station switches to the second connection to send one or more second message frames of the network access request, switching to a plurality of different connections according to the capability information value to send one or more second message frames simultaneously; or to a plurality of different connection orders to send one or more second message frames.

In the embodiment of the disclosure, the station may perform, according to the indication information and the capability information value sent by the AP, the sending of authentication request and the sending of one or more message frames such as the negotiation of the IP address (DHCP request) under other connection (second connection). The transmission of the plurality of message frames may be performed simultaneously under different connections or sequentially under different connections.

When the station in the embodiment of the disclosure converts to a plurality of different connection sequences to send a plurality of second message frames, the previously sent second message frames include identification information, and the second message frames are identified to be message frames sent in the multi-connection sequence through the identification information. When the message frames are sequentially transmitted under different connections, an identifier can be added in the message frame transmitted in advance to indicate the AP that the message frames are transmitted simultaneously.

Fig. 3 is a flowchart illustrating an initial access method according to an exemplary embodiment, which is used in an AP, as shown in fig. 3, and includes the following steps.

In step S31, a first message frame of a network access request sent by a station on a first connection is acquired, where the first message frame includes a capability information value supported by the station.

In step S32, a second connection is determined from the capability information value and indication information is sent, the indication information being used to indicate the second connection determined from the capability information value. Wherein the first connection is different from the second connection. For example, the first connection may be a bandwidth in the 2.4GHz band and the second connection may be a bandwidth in the 6-7GHz band. But may also be different bandwidths in the same frequency band.

In step S33, the second connection is switched to receive a second message frame of the network access request.

In the embodiment of the disclosure, the AP acquires a first message frame sent by the station on the first connection, where the first message frame includes a capability information value supported by the station. The AP determines a second connection different from the first connection according to the capability information value, sends indication information to the station, and converts the second connection to a second message frame for receiving a network access request, so that the occurrence probability of communication conflict in the initial network access process can be reduced.

In step S41, a beacon frame is broadcast, where the beacon frame includes an AP-supported connection, a BSS load under the AP-supported connection, and BSS Access delay average. The beacon frame may also include other information related to the connection.

In step S42, a first message frame sent by the station is acquired.

If the terminal detects the beacon frame broadcasted by the AP, the first message frame includes association request. If the terminal does not hear the beacon frame broadcast by the AP, the first message frame includes a probe request.

In step S43, a second connection different from the first connection is determined based on the capability information value supported by the station, BSS load, and BSS Access delay average.

The capability information value supported by the station includes supporting simultaneous transmission and reception under multiple connections or supporting simultaneous transmission or reception under multiple connections.

In step S44, indication information for indicating the second connection is transmitted.

Wherein the beacon frame includes the connections supported by the AP, BSS load and BSS Access delay average for the AP under this connection, and the aforementioned information under other connections.

In step S52, the station transmits a first message frame under the first connection, the first message frame including capability information values supported by the station. The AP receives a first message frame sent by the station.

If the station monitors the beacon frame broadcast by the AP, the station sends association request frames under the connection of receiving the beacon frame broadcast by the AP. Or if the station does not monitor the beacon frame broadcasted by the AP, the station sends a probe request under any connection and then sends association request frames.

For example, if the BSS load in the second connection is smaller than the BSS load in the first connection and the value of BSS Access Delay in the second connection is smaller than the value of BSS Access Delay in the first connection, the second connection is selected to transmit the second message frame.
