Abstract
In small multi-functional base stations such as 230 MHz power wireless private network LTE, when there is concurrent transient access of a large number of terminals, issues such as packet blocking and loss frequently occur, severely degrading overall system performance. To this end, the total delay during data transmission and queuing in the massive concurrent access of the power wireless private network is modeled, and a carrier allocation optimization method based on the optimized heuristic algorithm - immune algorithm is proposed. First, for the multi-objective problem with high real-time data requirements and packet loss rate requirements in the problem, an operational research model of data delay mechanism is constructed with the total data transmission delay as the objective function; An optimal resource allocation method based on immune algorithm is proposed to optimize the solution process; The minimum existence and convergence of the data delay model were analyzed and proved. The experimental results show that in the case of massive concurrent access, the proposed method enables the base station to maintain more stable performance under carrier limitations and massive concurrent access.
