Time slot scheduling method based on TDMA protocol and self-organizing network control system

Abstract

The invention belongs to the technical field of network communication, and discloses a time slot scheduling method based on a time division multiple access (TDMA) protocol and a self-organizing network control system. The method includes the steps of evaluating a time slot resource utilization state; when time slots need to be reserved, determining the number of the reserved time slots, using a Hash algorithm to determine reserved time slot information, sending data frames carrying the reserved time slot information, directly perceiving time slot conflicts, and indirectly perceiving the time slot conflicts; and when the time slots need to be released, determining the number of the released time slots, determining release time slot information through the Hash algorithm, and sending a timeslot release frame. According to the invention, a mechanism of simultaneous reservation and use is provided to achieve the purpose of rapid reservation and release. Meanwhile, a double conflict detection mechanism is provided, the purpose of shortening conflict decomposition time is achieved, and the time slot reservation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a time slot scheduling method based on time division multiple access (TDMA) protocol and an ad hoc network control system. Background technique [0002] At present, the commonly used existing technology in the industry is as follows: in the self-organizing network of time division multiple access technology TDMA, the traditional time slot reservation and release process mostly adopts the control interaction process of handshake. Good results are obtained when the network environment is good and appointment releases are infrequent. When the traffic of a node changes too frequently, a large amount of time slot resources are used to send handshake information through handshake reservation and release, which will cause a decrease in time slot utilization. When the network environment is bad, the resource reservation signal sent cannot guarantee timely feedb...

Problems solved by technology

However, the disadvantage of this method is that when the business volume changes frequently, the SA information cannot reflect the resource scheduling situation in time, and there is a problem of high resource reservation conflict probability

However, the disadvantage of this method is that there is a complex control information interaction process. When the network environment is not good, there is a problem of frequent interaction of control information resulting in a low reservation success rate.

[0004] (1) Existing technology—when the business volume changes frequently, the SA information cannot reflect the resource scheduling situation in time, and there is a problem of high resource reservation conflict probability

[0005] (2) Existing technology 2 has a complex control information interaction process. When the network environment is not good, there is a problem of frequent interaction of control information resulting in a low reservation success rate

At the same time, the conflict acquisition mechanism is not considered, and there is a problem of untimely acquisition of resource conflicts
