Method and apparatus for providing selectable roaming and non-roaming alarms
First Claim
1. A method for providing selectable roaming and non-roaming alarms for a communication device having a home communication area with a home time zone information, comprising the steps of:
- setting an alarm within the communication device;
selecting whether the alarm is to be referenced to the home time zone information or to a local time zone information;
wirelessly receiving a current local time zone information associated with each of a plurality of local communication areas from each of a plurality of local communication systems when the communication device roams into each of the plurality of local communication areas;
updating the local time zone information using the received current local time zone information associated with the current local communication area in which the communication device is located; and
triggering the alarm using the time zone information selected for the alarm to be referenced to in the selecting step.

Abstract
A communication device such as pager (100) includes a real-time clock circuit (118). The real-time clock circuit keeps track of both the pager'"'"'s home time zone information (402) and the pager'"'"'s current time zone information (404). While the pager user is operating within his home area, the pager'"'"'s home time zone information (402) and the current or local time zone information (404) will be the same. If the user however travels away from his home system'"'"'s time zone, the real-time clock circuit adjusts the current time zone information (404) to reflect the time zone the user is currently operating in. The user can set alarms which reference either the home time zone information (402) or the current time zone information (404). This allows for more user flexibility on how the alarm conditions are to operate.

5. A method as recited in claim 1, wherein the alarm is set to be referenced to the communication device'"'"'s home time zone information, and further wherein the communication device enters a communication area having a different time zone information than the home time zone information, the method further comprising:
-
comparing the alarm to a predetermined lock out period; and
preventing the alarm from generating an audible alert when the alarm falls within the predetermined lock out period.
-
-
6. A method as recited in claim 1, wherein the alarm activates an alert condition once within a predetermined period of time when the communication device operates within two or more different time zones.
-
7. A method for providing an alarm for a communication device, comprising the steps of:
-
providing to the communication device a first real time clock information referenced to a first time zone;
wirelessly providing to the communication device a second real time clock information referenced to a second time zone, wherein the communication device is currently operating in the second time zone, and further wherein the second real time clock information is provided from a communication system within the second time zone;
setting an alarm which is referenced to either the first real time clock information or the second real time clock information;
wirelessly providing to the communication device a third real time clock information referenced to a third time zone, wherein the communication device is currently operating in the third time zone, and further wherein the third real time clock information is provided from a new communication system within the third time zone; and
updating the reference for the alarm to the third real time clock information when the alarm is set to reference the second real time clock information. - View Dependent Claims (8, 9, 10)
transmitting an update message to the pager upon the pager roaming into an operating area which is in a different time zone than the operating area from which the pager departed.

11. A communication device having a home communication area and operable in at least one other communication area located in a different time zone than the home communication area, comprising:
-
a receiver for wirelessly receiving a current local real time clock information associated with each of a plurality of local communication areas from each of a plurality of local communication systems when the communication device roams into each of the plurality of local communication areas;
a real time clock circuit for maintaining a home real time clock information associated with the home communication area and for maintaining the local real time clock information associated with the at least one other communication area; and
a controller coupled to the receiver and coupled to the real time clock circuit, wherein the controller is programmed to;
set an alarm which is referenced to either the home real time clock information associated with the home communication area or the local real time clock information associated with at least one of the plurality of communication areas, update the local real time clock information using the received current local real time clock information associated with the current local communication area in which the communication device is located, and trigger the alarm using the real time clock information in which the alarm is referenced. - View Dependent Claims (12, 13, 14)
