Description
Technical Field
The invention relates to the technical field of communication, in particular to a channel access configuration system based on a communication technology.
Background
Access channel technology refers to providing a mobile station to base station transmission path before the mobile station does not occupy a traffic channel. The access channel is used for a mobile station to initiate a call or respond to paging of a base station, and to send registration messages to the base station, etc. The access channel corresponds to the paging channel of the forward link. It is characterized by that every user can not access channel at will, and must obey a certain control. But also can be divided into centralized control and decentralized control.
All users can randomly send information to the channel according to own will. When two or more users both transmit information on a shared channel, a collision occurs, which results in a failure of the user's transmission. Random access technology is mainly to study network protocols that resolve collisions. Random access is in fact a contention access, and the contention winner may temporarily occupy the shared channel to transmit information. The random access is characterized in that stations can transmit data at any time, contend for channels and are easy to conflict, but the random access can flexibly adapt to the number of stations and the change of the traffic of the stations.
In a common communication system, there are 3 channel access modes: point-to-point, point-to-multipoint, and multipoint sharing. Point-to-point is the simplest way of channel sharing. It is characterized in that only two nodes share a wireless channel. In the single channel, two nodes can share in a half duplex mode, and in the double channel, full duplex communication can be realized. Point-to-multipoint is typically used for wireless channels with fixed infrastructure control, such as wireless channels of cellular mobile systems. At this time, the terminals share one or more radio channels under the control of the central station. Multipoint sharing refers to a plurality of terminals sharing one broadcast channel. Ethernet is the most typical multipoint sharing mode in which one terminal transmits a signal and all terminals can hear, i.e. it corresponds to a fully interconnected network.
At present, when a client device and a server device perform signal transmission, a direct access channel performs data signal transmission, channels are not screened, when the signal transmission of the access channel is problematic, the signal transmission can only be performed after re-access.
