Problems solved by technology

In the wireless communication network system, when the number of nodes or the number of local nodes changes greatly, the use efficiency of many static or quasi-static time slot access methods is very low, and the use of CSMA-type competitive access methods The efficiency is improved compared with the static or quasi-static time slot access method, but when the number of nodes is large, the efficiency also plummets

Embodiment

[0029] The dynamic time slot allocation and access method of the frequency hopping radio station of the present invention, after the main station and the cluster stations are connected, first search for networking, after the networking is successful, it automatically enters the steps of business declaration, business response and data transmission, as follows Each step is described in detail:

[0030] Step (1) Search for network construction: the master station sends synchronization information hop by hop in its own time slot (L frequency points), and each slave station enters a long search process (length L+1), and receives the master station in a fixed frequency window. Station network synchronization information. After the slave station captures the network access synchronization information of the master station, it updates its own system information, keeps in sync with the master station, and broadcasts the information in its own time slot; The frequency pattern remains ...

Abstract

The invention provides a dynamic time slot allocation access method for the networking of a frequency-hopping radio station. The method comprises the following steps of: networking, which comprises dividing an integrated frame into a statement sub-frame, an answering sub-frame and a data transmission sub-frame; dividing the sub-frames into N sub time slots according the number N of network nodes; and determining a main time slot of each node; time-slot division; service statement; service answering; decision making; and data transmission. In the method, alternative time slots of active nodes are allocated by adopting a priority strategy, so that the problems of a concealed terminal and an exposed terminal are avoided, and the utilization ratio of the time slots is increased.

Description

technical field [0001] The invention relates to a time slot access method of a mobile communication network system, in particular to a dynamic time slot allocation access method of a frequency hopping radio station network. Background technique [0002] Among all the applications and services of mobile wireless communication, the usage rate of wireless channel and the total traffic of wireless network are the most urgent content to be improved in system design. In the wireless communication network system, when the number of nodes or the number of local nodes changes greatly, the use efficiency of many static or quasi-static time slot access methods is very low, and the use of CSMA-type competitive access methods The efficiency is improved compared with the static or quasi-static time slot access method, but when the number of nodes is large, the efficiency also plummets. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies of the prio...
