Description
Technical Field
The invention relates to the technical field of communication, in particular to a channel access configuration system and a channel access configuration method based on a communication technology.
Background
Access channel technology refers to providing a transmission path from a mobile station to a base station 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 a page from a base station, and for a registration message, etc., to be sent to the base station. The access channel corresponds to a paging channel of the forward link. The characteristic is that each user can not access the channel freely and must obey certain control. And can be divided into centralized control and decentralized control.
All users can randomly send information to the channel according to own wishes. When two or more users transmit information on a shared channel, a collision occurs, which results in a transmission failure of the users. The random access technology is mainly a network protocol for solving conflicts. Random access is actually contention access, and the contention winner can temporarily occupy the shared channel to transmit information. The random access is characterized in that the stations can send data at any time, contend for channels and are easy to collide, but the random access can flexibly adapt to the number of the stations and the change of the communication traffic.
In a general communication system, there are 3 channel access methods: point-to-point, point-to-multipoint, and multipoint sharing. Point-to-point is the simplest way to share a channel. It is characterized in that only two nodes share a wireless channel. In single channel, two nodes can share in half duplex mode, and in double channel, full duplex communication can be realized. Point-to-multipoint is typically used for radio channels controlled by a fixed infrastructure, such as the radio channels of a cellular mobile system. At this time, the terminals share one or more wireless channels under the control of the central station. The multipoint sharing means that a plurality of terminals share one broadcast channel. Ethernet is the most typical multicast mode, in which a terminal sends 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 send signals, a channel is directly accessed to send data signals, the channel is not screened, when the signal transmission of the access channel goes wrong, the channel can only be accessed again to transmit the signals, the method aims at screening the optimal channel in real time, monitoring the channel parameters of each channel to perform signal delay analysis, and adopting a standby channel to perform signal state synchronization.
