10 1. Configuration Overview Configuration Flow After the BaiCells is powered on, one needs to configure its data and launch the base station so that users can get their access to the voice and data service. The configuration procedure is shown in Figure 1-1. Figure 1-1 Base Station Configuration Procedure Data Preparation Before configuring the base station s data, data planning needs to be done first. The data to configure includes local parameters and connecting parameters. These parameters are either provided by the user or determined after negotiation with the customers. The data to prepare include IP address, cell parameters, protocol parameters, software version, and so on.

11 2. Login Web Client Web Client Environmental Requirements Table 2-1 describes the requirements on computer of the client.

Scheduling Algorithm Scheduling is an important insurance for the good operation of the wireless data service. Scheduling algorithms have a general impact on key performance indicators like the cell throughput, cell edge user throughput, VoIP capacity, and QoS of data service. Scheduling strategies commonly used are: MAXC/I algorithm: allocate the resource and opportunities to terminals in favor of those with good channel quality. QoS not taken into account, and memory not used. PFS algorithm: balance between user channel quality and fairness, both cell 35

46 throughput and user fairness taken into account. RR algorithm: allocate the resource and opportunities to all terminals equally. QoS not taken into account, and memory not used. 1.
