Abstract

A wireless telephone having a user-selectable pager mode in which, in response to a page message associated with an incoming call, the wireless telephone transmits a data message which causes the incoming call to be redirected to a voice mail system without delay due to a system-determined time interval for allowing wireless telephone users to answer incoming calls.

Claims

1. A wireless telephone designed for operation in a wireless telephone system having a system-determined time interval for allowing wireless telephone users to answer incoming calls, said wireless telephone having an operational mode selectable by a user wherein, in response to a page message associated with an incoming call directed to said wireless telephone, said wireless telephone transmits a data message to cause said incoming call to be redirected to a voice mail system without delay due to said system-determined time interval, wherein said data message is a power down registration.

2. The wireless telephone according to claim 1, wherein, immediately following transmission of said power down registration, said wireless telephone transmits a power up registration.

3. The wireless telephone according to claim 1, wherein said data message is an acknowledgement message containing a service rejected instruction.

4. A wireless telephone designed for operation in a wireless telephone system having a system-determined time interval for allowing wireless telephone users to answer incoming calls, said wireless telephone having an operational mode selectable by a user wherein, in response a page message associated with an incoming call directed to said wireless telephone, said wireless telephone transmits a power down registration to cause said incoming call to be redirected to a voice mail system without delay due to said system-determined time interval, immediately followed by a power up registration, to a switching office from which said page message originated.

5. The wireless telephone according to claim 4, wherein, in response to said page message, said wireless telephone:

(a) emits a signal to alert a user to said incoming call;

(b) displays caller identification information associated with said page message on a screen of said wireless telephone; and

(c) pauses for a predetermined time interval to allow the user to answer said incoming call before transmitting said power down registration.

6. A wireless telephone designed for operation in a wireless telephone system having a system-determined time interval for allowing wireless telephone users to answer incoming calls, said wireless telephone having an operational mode selectable by a user wherein:

(a) said wireless telephone distinguishes between a first type of incoming call that has been designated as a high priority call in a memory of said wireless telephone and a second type of incoming call that has not been so designated; and

(b) in response to a page message associated with said second type of incoming call to said wireless telephone, said wireless telephone transmits a power down registration to cause said second type of incoming call to be redirected to a voice mail system without delay due to said system-determined time interval.

7. The wireless telephone according to claim 6, wherein said wireless telephone compares caller identification information contained in a page message associated with an incoming call with information stored in the memory of said wireless telephone to determine whether said incoming call has been designated as a high priority call.

8. The wireless telephone according to claim 6, wherein, in response to said page message associated with said second type of incoming call, said wireless telephone:

(a) emits a signal to alert a user to said incoming call;

(b) displays caller identification information associated with said page message on a screen of said wireless telephone; and

(c) pauses for a predetermined time interval to allow the user to answer said incoming call before transmitting said power down registration.

9. In a wireless telephone, a method for redirecting incoming calls to a voice mail system, the method comprising the steps of:

(a) receiving a page message from a wireless telephone switching office;

(b) emitting a signal to alert a user of said wireless telephone to an incoming call;

(c) displaying caller identification information associated with said page message on a screen of said wireless telephone;

(d) pausing for a predetermined time interval to allow the user to answer said incoming call;

(e) if said incoming call is not answered, transmitting a power down registration, immediately followed by a power up registration, to said wireless telephone switching office, whereby said incoming call is redirected to a voice mail system.

10. The method according to claim 9, wherein said wireless telephone is designed for operation in a wireless telephone system having a system-determined time interval for allowing wireless telephone users to answer incoming calls, and said incoming call is redirected to a voice mail system without delay due to said system-determined time interval.

11. The method according to claim 9, further comprising the steps of:

receiving a data message from said voice mail system, and (g) displaying information contained in said data message on a screen of said wireless telephone.

12. The method according to claim 11, wherein said data message comprises at least one of:

(a) an alpha-numeric message prepared by a caller who initiated said incoming call, and (b) a data message prepared by said voice mail system in response to a voice message recorded by said caller.

13. In a wireless telephone, a method for selectively redirecting incoming calls to a voice mail system, the method comprising the steps of:

(a) receiving a page message from a wireless telephone switching office, said page message including caller identification information;

(b) comparing said caller identification information with information stored in a memory of said wireless telephone to determine whether said incoming call has been designated as a high priority call;

(c) if said incoming call has not been preselected as a high priority call, (i) emitting a signal to alert a user of said wireless telephone to said incoming call, (ii) displaying said caller identification information on a screen of said wireless telephone, (iii) pausing for a predetermined time interval to allow the user to answer said incoming call, and (iv) if said incoming call is not answered, transmitting a power down registration, immediately followed by a power up registration, to said wireless telephone switching office, whereby said incoming call is redirected to a voice mail system.

14. The method according to claim 13, wherein said wireless telephone is designed for operation in a wireless telephone system having a system-determined time interval for allowing wireless telephone users to answer incoming calls, and said incoming call is redirected to a voice mail system without delay due to said system-determined time interval.

15. The method according to claim 13, further comprising the steps of:

(v) receiving a data message from said voice mail system, and (vi) displaying information contained in said data message on a screen of said wireless telephone.

16. The method according to claim 15, wherein said data message comprises at least one of:

(a) an alpha-numeric message prepared by a caller who initiated said incoming call, and (b) a data message prepared by said voice mail system in response to a voice message recorded by said caller.
