Method and device for wireless network access, terminal equipment

Abstract

The present invention provides a method and device for wireless network access, and terminal equipment. The method includes: determining the working cycle of the wireless access point AP, and the working cycle includes the preset duration corresponding to each service type and the corresponding time period of each service type. The position of the duration of each service type in the working cycle; the duration of each service type and the position of the corresponding duration of each service type in the working cycle are based on the service type, and / or channel quality, and / or the service requirements of each terminal device to be accessed, And / or determine the priority of each terminal device to be accessed; perform information interaction with each terminal device in a determined working cycle, and complete the wireless network access of each terminal device. The present invention realizes the synchronous transmission and reception of uplink and downlink data between different APs, reduces cross interference, improves resource utilization and the success probability of competitive access, reduces the waiting time for connected terminal equipment to send uplink data, reduces service transmission delay, and reduces terminal equipment power consumption, improving the service quality and perception of terminal equipment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and terminal equipment for wireless network access of a time-division wireless coverage system. Background technique [0002] TDMA (Time Division Multiple Access) is a wireless communication technology for sharing transmission media or networks, which allows multiple users to use the same frequency in different time slots, such as GSM (Global System for Mobile Communication , Global System for Mobile Communications) system and WLAN (WirelessLocal Area NetWork, wireless local area network) system. The minimum time slice in the GSM system is a time slot, the length of the time slot is a fixed value, and the hyperframe composed of time slots is also a fixed length. In the GSM system, time slots used by different control channels need to be configured. The time slice for sending data is limited; and the IEEE 802.11 standard adopted by the WLAN...

Problems solved by technology

PCF sends data frames in a superframe cycle. Each superframe cycle includes a contention-free phase CFP (Contention-Free Periodd) and a contention phase CP (ContentionPeriond). The CFP phase transmits real-time services, PCF works, and CP During the transmission of non-real-time services, DCF works; but during the CFP period, the AP still needs to listen to the medium. After the AP detects that the channel idle time reaches PIFS (PCF Inter-frameSpacing, point coordination function inter-frame spacing), the AP sends a message containing The beacon frame of CF (Coordination Function, coordination function) parameter set information, after sending the beacon frame for initializing CFP, AP waits at least one SIFS (Short Inter-frame Spacing, short inter-frame spacing), and then sends data frame or round-robin according to the situation Inquiry frame; the AP inquires the associated terminal devices respectively according to the polling list, and the terminal devices must be polled before transmitting data; this method requires the AP to determine the CFP initiation time, and the AP needs to send a polling frame to inform the terminal device whether There is still a waste of resources to a certain extent, and the real-time nature of user data scheduling is still not guaranteed; and during the CFP period, the terminal device needs to always listen to whether the polling frame is sent to itself, so the terminal device function waste on consumption
