Abstract: A wireless communications system is presented where a mobile station is able to automatically determine its proximity to a second mobile station or landline telephone. Once the proximity determination command has been given, no further actions are required by the users of either telephone. A GPS receiver connected to the first mobile station is able to provide that mobile with its position and direction. The first mobile station makes a request to the other telephone for its position, through SMS messaging for example. A GPS receiver connected to the second mobile station is able to provide the second mobile station with data to enable the position request. Trust determinations can be enabled so that position data is sent to a restricted list of requesting telephone numbers. Likewise, the second mobile station can request position data from the first mobile station. When position information is requested from a landline telephone, the request can be fulfilled by the landline telephone service provider.

Abstract: A personal information manager (PIM) has been provided for use in controlling telephone call message responses for a wireless communications network mobile station telephone. The PIM permits a telephone user to program a unique response for each calling party. Typical responses including the normal audible alert, automatically transferring the call to voice mail, and silent ringing with no voice mail, to name but a few options. In addition, the matrix of calling parties and corresponding message responses can be modified for different times of the day or circumstances. For example, the PIM can be programmed to deliver a different set of responses during normal work hours than the responses provided at night, or during a business meeting.

Abstract: A system and method have been provided that permit a mobile station to enter a deep-sleep slotted mode of operation in response to detected patterns of low traffic communications. A record of traffic communications is maintained at either the mobile station, or in the wireless communications network. Analysis of the record indicates whether the mobile station should be operated in the deep-sleep mode. Then, the deep-sleep mode, with a larger period between control messages, is negotiated. In some aspects of the invention, the period between control messages is a function of the likelihood of a traffic communication occurring.
