Embodiment Construction

[0019] The present invention will be described in further detail below:

[0020] As we all know, polling intervals or working time slots can be reasonably designed according to statistical characteristics, and each time slot is divided into two stages: base station (AP) downlink and client terminal (CPE, ie mobile station) uplink.

[0021] The base station (AP) acts as the network polling "controller". In order to more effectively handle the communication needs of the mobile station, the base station divides customer equipment (CPE) into two types. The first type (Type A) is an active station, usually a station that has been sending data or maintaining communication continuously, and is usually placed in a "hot" active queue; the second type (Type B) is a dormant station or a low-frequency operation "Lazy" sites, usually sites with no poll responses or low response times, are treated as inactive queues.

[0022] Priority in most networks is designed for customer premises equ...

Abstract

The invention discloses a terminal-oriented TDMA two-stage time slot management method, and the method is used for the time slot management according to the type of customer terminals. The method comprises the steps: classifying the actual application demands of the customer terminals into a high-stage class, a middle-stage class and a low-stage class according to the delay sensitive degree, bandwidth demands and priority; dividing the time slot distribution of each customer terminal into a high stage, a middle stage and a low stage according to the bandwidth demands; dividing the time slot scheduling of each customer terminal into a high stage, a middle stage and a low stage according to the delay sensitive degree and the priority; dividing all connected customer terminals into a first stage polling queue and a second stage polling queue according to the priority and the delay sensitive degree; carrying out the polling of the above two polling queues through employing a two-layer polling system; and enabling the customer terminal meeting a predetermined condition to move to or to be removed from a non-active queue when the polling is finished. The method improves the time slot utilization rate, optimizes the waiting time of the customer terminals with the low delay demands, solves a conflict between the number of time slots and the polling frequency, and improves the task adaptability.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a terminal-oriented TDMA two-stage time slot management method. Background technique [0002] Reliable interconnection is an important factor to ensure the combat effectiveness of troops, especially in the field marching state, communication on the move is an important issue of military / convoy communication support. [0003] In recent years, with the continuous improvement of the army's informatization level, communication needs have continued to expand from traditional voice services to data services; at the same time, with the rapid increase of various information equipment, the number of communication nodes has also shown an exponential increase. trend. In this context, the traditional communication system designed mainly for voice services has become less and less suitable for the needs of the task. [0004] The wired network has the advantages of reliabil...
