Fast Cell Selection procedure considering network constraints in HSDPA

In this paper, the mobility management function for the High Speed Downlink Packet Access (HSDPA) system is investigated. This procedure is also known as the Fast Cell Selection (FCS), in that the cell change procedure is performed in a short amount of time trying to track the best cell instantaneously. We consider the User Equipment (UE) controlled cell selection, where the mobile user selects its serving cell based on channel measurements by sending uplink signaling. There are some limitations to this procedure regarding signaling overhead and that is the point discussed in this work. Some procedures are evaluated with the aim to minimize the signaling through the radio access network with little impact on the system performance.
