Method and device for reducing spending of control signal in mixed wireless network

Abstract

The invention provides a method for reducing the spending of a control signal in a mixed wireless network. The method comprises the following steps: a first terminal receives a wireless frame in the mixed wireless network and judges whether the received wireless frame is the reserved control frame of a wireless channel or not; if the received wireless frame is the reserved control frame of the wireless channel, the first terminal reads the value of a duration time domain in the reserved control frame of the wireless channel, utilizes the value of the duration time domain to update a channel reserved-time timer of the first terminal and does not update the network distribution vector of the first terminal; before the first terminal transmits a data frame, the condition that whether the remaining time of the channel reserved-time timer is larger than time required for transmitting the data frame or not is judged; and when the remaining time of the channel reserved-time timer is larger than the time required for transmitting the data frame, the first terminal directly transmits the data frame and does not transmit the reserved control frame of the wireless channel.

Description

technical field [0001] The present invention relates to a method and device for reducing control signaling overhead in a hybrid wireless network, in particular, to a method and device for improving voice service capacity and quality in a hybrid wireless local area network (WLAN) where data and voice are mixed . Background technique [0002] With the application of the voice service in the wireless local area network, a major problem it faces is that the control overhead of the wireless local area network itself is very large. This is a major factor affecting voice capacity in WLANs. [0003] Currently in the WLAN, the IEEE802.11 standard is mainly used to standardize the characteristics of the Media Access Control (MAC) layer and the physical layer in the WLAN. Among them, the MAC layer protocol defines the point coordination function (PCF, Point Coordination Function) for the contention free period (CFP, Contention Free Period) and the contention period (CP, Contention Pe...

AI Technical Summary

Problems solved by technology

First of all, these methods require that the network must have the PCF function, but most commercial equipment does not support this function

Therefore, in practical applications, the usability of existing methods will be reduced

Second, existing approaches require major changes to 802.11g access points (APs) currently in use, making them expensive to use and hindering rapid deployment
