Method and apparatus for controlling a quiet zone for wireless units
First Claim
1. In an IP-based cellular wireless communication system, a device comprising:
- a monitoring arrangement, the monitoring arrangement being arranged to detect a location of a cellular phone device with respect to an area of restricted access, wherein the location of the cellular phone device with respect to the area of restricted access is detected in part by determining when a preset period of time has elapsed; and
a sender arrangement, the sender being arranged to send a first message including information associated with the cellular phone device when the location of the cellular phone device with respect to the area of restricted access is detected;
wherein the location of the cellular phone device with respect to the area of restricted access represents a change from the cellular phone device being in the area of restricted access to the cellular phone device being out of the area of restricted access, the change being detected when the preset period of time has elapsed without a signal from the cellular phone device being detected by the monitoring arrangement.

Abstract
In one embodiment, a device in an IP-based cellular wireless communication system includes a monitoring arrangement and a sender arrangement. The monitoring arrangement arranged to detect a location of a cellular phone device with respect to an area of restricted access. The location of the cellular phone device with respect to the area of restricted access is detected in part by determining when a preset period of time has elapsed. The sender is arranged to send a first message including information associated with the cellular phone device when the location of the cellular phone device with respect to the area of restricted access is detected. A method for operating the device is also disclosed.

15. In an IP-based cellular wireless communication system, a method of operating a device comprising:
-
detecting whether a cellular phone device is within an area, the cellular phone device being serviced by a service provider control point, wherein detecting whether the cellular phone device is within the area includes determining when a preset period of time has elapsed; and sending a first message to the service provider control point when the preset period of time has elapsed, the first message including information associated with the cellular phone device when the location of the cellular phone device with respect to the area is detected; wherein the location of the cellular phone device with respect to the area of restricted access represents a change from the cellular phone device being in the area of restricted access to the cellular phone device being out of the area of restricted access, and detecting whether the cellular phone device is within the area includes detecting the change when the preset period of time has elapsed without a signal from the cellular phone device being detected. - View Dependent Claims (16, 17, 18, 19, 20)
