Abstract
Methods and apparatus are provided for collecting and detecting service area (SA) swapping noise in a wireless network including a plurality of SAs serving a plurality of devices. By receiving SA updates from the stationary devices of the plurality of devices changes in SA identifiers of the SA updates associated with each stationary device are detected. For each stationary device, if two or more SAs are detected to have changed for the stationary device, then these SAs are identified as contributing to SA swapping noise. With this in mind, SA transitions between the identified SAs for a non-stationary device of the plurality of devices are not interpreted as movement of the non-stationary device. However, SA transitions for the non-stationary device from these SAs to other SAs not contributing to SA swapping noise are interpreted as a change of location or movement of the non-stationary device.
