Description
Technical Field

Background
With the diversification of the communication demand of the smart grid, the application of a novel power wireless private network technology represented by a Long Term Evolution (LTE) technology in a power communication system is receiving more and more attention. The electric power wireless private network technology not only needs to guarantee the bandwidth and real-time reliability of electric power communication services, but also needs to have reliable and efficient support capability for mass services of the smart power grid. Therefore, the service access control performance of the power wireless private network is particularly important.
The existing access control mechanism mainly comprises a random competition access control class, a fixed time sequence distribution access control class and an on-demand distribution time sequence access control class. The random contention access control class is applicable to a case where traffic communication is performed discontinuously at a communication terminal, and when applied to continuous traffic, it causes traffic congestion. The fixed allocation time sequence access control class mainly allocates a fixed communication time sequence to the communication terminal, so that the communication terminal can utilize a channel to perform communication when service communication is desired, and the fixed allocation time sequence access control class is suitable for being applied to a service environment with continuous communication, such as voice communication service, video communication service and the like, but if the terminal has no information, the channel is in an idle state, and the spectrum resource of a wireless channel is wasted. The access control class of the time sequence is allocated according to the requirement, which is mainly characterized in that a terminal carries out communication by competing the use right of a channel when information is sent, the use right of the channel is transferred out after the communication is finished, and competition is carried out when the communication is needed next time, so that the access control class is suitable for the condition of communication state change.
In the actual scene of the power wireless private network, there are many situations, and the access performance is adversely affected by the LTE random access procedure. For example, after the power failure is recovered, all devices start to access the network after being electrified; and the metering terminal uploads the electricity consumption data at regular time. If the number of the access terminals is known, an optimal queuing access mode, that is, access control is allocated by using a fixed time sequence, can be preset, but in practical situations, the number of the access terminals is usually uncertain, and services with uncertain number can only complete access by using a random contention access control class.
Based on this, the inventor of the present invention finds that access is completed through random contention access control, and in an application scenario of a continuous communication service of a smart grid, massive concurrent service access may cause blocking, and further cause problems of service delay and the like.
