Analysis of Channel Element Resource Utilization Ratio in WCDMA/HSPA Network

With the rapid growth of WCDMA users, channel element resources of mobile stations have appeared congestions in different degree, which has seriously affected the quality of user experience. At present, for the situation of channel element resources congestion of mobile stations, we commonly analyze the stations and make an expansion plan after a complaint in this area or many accesses failure or a lot drop calls of the stations. Meanwhile, when there are channel element expansion plans, we usually choose a region no matter if there are stations that need channel element expansion really. Thus, it will make the waste of resources inevitably. This paper will analyze the channel element resource utilization ratio deeply, build specific simulation model, and quantify the effect of channel element resource utilization ratio on the key indexes of the WCDMA/HSPA network. Then, the paper will give suggestions on configuring channel element resources of network more reasonably, to improve network performance, save network investment, provide important references on network optimization and operating maintenance for mobile operators.
