Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] 1. Division of time slots

[0043] The length of the time slot (Time Slot) specified in Link16 is 7.8125ms, and there are 128 time slots per second; 1536 time slots form a frame (frame), and the length of a frame is 12s; 2 6 =64 frames are an epoch (or time period), and the length of an epoch is 12.8 minutes, including 98304 time slots; thus 112.5 epochs are included in 24 hours a day. The time slots are divided into three groups in frames and epochs, namely Group A, Group B, and Group C. Each group in a frame contains 2 9 = 512 time slots, each group in an epoch contains 2 15 =32768 time slots; the time slot labeling method in a frame is A-0, B-0, C-0, ..., A-511, B-511, C-511; the labeling method of a frame in an era is frame -0, frame-1, ..., frame-63, the time slot labeling method is A-0, B-0, C-0, ..., A-32767, B-32767, C-32767...

Abstract

A time slot block serial number representation method-based time slot allocation method includes the following steps of: step one, determining the types of network participating groups and the size of required time slot blocks; step two, performing time slot allocation based on a minimum time slot block serial number; step three, determining time slot blocks of the network participating groups which are represented by time slot block serial numbers; and step four, calculating time slot blocks of the network participating groups which are represented by a conventional representation method. With the time slot block serial number representation method-based time slot allocation method of the invention adopted, the problem of incapability of realizing direct mapping of time slots allocated by the network participating groups into determined time slot blocks can be solved, and difficulties in time slot resource planning and allocation can be eliminated; time slot blocks which are obtained through time slot allocation based on the time slot block serial numbers will not conflict with each other; when a large number of network participating groups and network participating members exist, time slot resources can be effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of communications, and relates to a time slot allocation method, in particular to a time slot allocation method based on a time slot block serial number representation. Background technique [0002] Link16 is a large-capacity, confidential, anti-jamming, time-division multiple access tactical information distribution system used by the United States and other NATO countries. It is the most important tactical data link for the United States and other NATO countries. In several local wars such as the Iraq War, Link16 played an important role, showing its powerful power as a "combat effectiveness multiplier". Researching the key technology of Link16 data link is of great significance to the research and development of similar data link of our army. [0003] Link16 adopts time division multiple access (TDMA) technology, and time slot is the basic communication unit of TDMA data link. First, time slots are allo...
