Impact on Radio Network Performance

The impacts of different uplink admission control algorithms are as follows: ALGORITHM_OFF: The uplink admission control algorithm is disabled. The cell may be congested because it admits too many users. Disabling this algorithm affects system stability. ALGORITHM_FIRST: The network performs admission control based on the uplink cell power load and the predicted power load caused by admitting new users. This algorithm prevents excessive user access, enhancing system stability. ALGORITHM_SECOND: The network performs admission control based on the uplink equivalent number of users (ENU) of the cell and the predicted ENU caused by admitting new users. This algorithm prevents excessive user access, enhancing system stability. ALGORITHM_THIRD: Compared with ALGORITHM_FIRST, this algorithm does not predict the load increment caused by admitting new users. Therefore, this algorithm makes it easier for user access. ALGORITHM_FOURTH: Compared with ALGORITHM_FIRST and ALGORITHM_THIRD, this algorithm admits more users when the cell serves a few users but bears a high traffic volume (high RTWP). In this case, this algorithm increases user access success rate. Compared with ALGORITHM_SECOND (especially when its [PARA]UlTotalEqUserNum[/PARA] parameter is set to a large value), this algorithm may set tight requirements on user access and the number of admitted users decreases.
