Section: A.28 Monitor of the number of active UEs
Content: The number of the active UEs in each cell is a valuable measurment for operators to know how many UEs are with buffered data per cell basis. This kind of information can help operators to tune the admission control parameters for the cell and to do load balancing between cells to ensure that the target percentage or number of the UEs admitted achieve the target QoS. However, the number of single uplink or downlink UEs can not effectively reflect the actual number of active UEs either on the downlink or on the uplink in the network. As the active UEs reflect UEs have data to transmit or receive , the ratio of the number of active UEs to the number of the RRC connected UEs can be established, which can be used to monitor the the cell. In addition, compared with the number of RRC connected users, the number of active UEs is a more effective measurement to reflect the control plane capacity of wireless network.
