Portable Communication System Transfer Initiation Resolution

This Study relates to (1) idle mode cell resection by a mobile unit, or (2) a handover (transfer) of an ongoing call in a mobile unit. The cell reselection or handover of the mobile unit is to another cell in a mobile radio network including a multitude of cells, with each cell having an association with a base station for supporting communications with a mobile unit such as a cell phone. 

Relevant references must describe the following elements to be of interest:

• at the mobile unit, monitoring the quality of a signal that is transmitted between a variety of candidate base stations and the mobile unit;

• based on the monitored signals, producing an indication of the rise or fall of each base station’s signal quality as a function of time;

• sending a signal from the mobile unit to the base station to initiate transfer (handoff or cell reselection) from the currently selected/serving base station to a different base station where the new base station is chosen based on indication of the rise or fall of the base station’s signal quality as a function of time; and

• setting a level of priority of handover contingent upon the results of the monitored quality of the transmitted signal.
