Confirming method for controlling frequency point access time of day in non-center system

Abstract

The present invention discloses a method to confirm control frequency point access time in a centreless system including procedures below: Procedure I. Firstly, state of a service frequency point is detected with selected channels marked with A and B; Procedure II. It is necessary monitor whether other broadcasting stations are operating on the control frequency point and judge whether the channel A and channel B are stipulated by other broadcasting stations. If the channel A and channel B are stipulated, please turn to procedure I. As for the channel A and channel B stipulated and unused on the control frequency point, please go to procedure; III. Otherwise, turn to procedure IV; Procedure III. If the control frequency point is not used, a primary call is realized; Procedure IV. As for the control frequency point in operation, please judge whether the channel A serves as a service channel. If yes, the channel B is stipulated as a service channel. If not, please reserve the channel A and turn to procedure V; Procedure V. As other broadcasting stations operate on the control frequency point, wait for a time slot T at random and go to procedure II. The present invention can not onlyrealize synchronization between a calling and a called broadcasting station and avoid collision with other broadcasting stations.

Description

technical field [0001] The present invention relates to a wireless communication system, relates to a scheme for realizing time synchronization of business channels, synchronization channels, paging channels, control channels, etc. Determine the method. Background technique [0002] At present, in the existing digital centerless communication system, there is no control of the central node, and direct communication can be realized between terminals. In a centerless communication system, the design of the structure, synchronization agreement, call signaling process, and terminal status will affect the performance of the entire system; and the control frequency point carries a public channel, and the station must follow a certain random access protocol in order to effectively avoid collision. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for determining the access time of the control frequency point in...
