Problems solved by technology

However, this solution is relatively simple to implement, for example, it does not consider the deterioration of the air interface environment caused by the increase in the number of STAs, so the time fair effect it can achieve is not ideal

Embodiment approach

[0050] Furthermore, the above formulas (1) and (2) only consider the STA type and the 802.11 protocol fixed overhead corresponding to the STA type. Impact of bandwidth occupied by STAs. Then the AP adjusts the initial bandwidth of the first STA in the current scheduling period according to the total number of STAs accessing the AP in the current scheduling period, and obtains an optional implementation mode of the available bandwidth of the first STA in the current scheduling period include:

[0051] If the total number of STAs accessing the AP in the current scheduling period is greater than or equal to the preset first number threshold and less than or equal to the preset second number threshold, the AP obtains the first STA's current scheduling period according to formula (3). available bandwidth within

[0052] If the total number of STAs accessing the AP in the current scheduling period is greater than the second number threshold, the AP obtains the available bandwidth ...

Abstract

The invention provides a dispatching method, a dispatching device and network equipment. The method comprises the following steps: acquiring the dispatching information of a dispatching cycle prior to the current dispatching cycle through an AP (Access Point) based on the type of a first STA (station); determining the initial bandwidth of the first STA in the current dispatching cycle through the AP based on the dispatching information, and adjusting the initial bandwidth of the first STA within the current dispatching cycle based on the total number of the STAs accessed into the AP within the current dispatching cycle, and acquiring a usable bandwidth of the first STA within the current dispatching cycle; setting by the AP the number of tokens of a token bucket corresponding to the first STA within the current dispatching cycle based on the usable bandwidth of the first STA within the current dispatching cycle, and receiving and transmitting a message corresponding to the first STA according to the number of the tokens of the token bucket corresponding to the first STA within the current dispatching cycle. With adoption of the dispatching method, the dispatching device and the network equipment, the fairness of equipment using a WLAN (Wireless Local Area Network) resource within the WLAN can be improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a scheduling method, device and network equipment. Background technique [0002] The wireless local area network (Wireless Local Area Network, WLAN for short) is deployed more and more widely, and the most widely used standard is the IEEE 802.11 series. The 802.11 standard WLAN adopts the Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA) mechanism, which provides a half-duplex wireless link. Only one device can send data on the link within a segment, while other devices sharing the same link can only receive data from the link in the same period of time, otherwise the wireless signal on the link will be destroyed, thus causing the transfer to fail. In order to ensure the exclusive realization of the above signal, the 802.11 standard introduces three media access modes: Distributed coordination function (DCF for short), point coordination function (PCF for short...
