Abstract

A method includes the steps of (a) storing at least one predetermined telephone number in a memory (24, 24a) of a mobile station (10); and (b) in response to the receipt of an incoming call indication when a silent service mode is active, comparing at least a portion of the telephone number of the calling party to the stored at least one predetermined telephone number. If the received calling party number matches one of the stored numbers, the method executes a step of generating an audible alert to inform the user of the presence of the incoming call. If the received calling party number does not match one of the stored numbers, the method instead executes a step of inhibiting the generation of an audible alert. In one embodiment of this invention the step of generating an audible alert generates a predetermined audible alert that is different from an audible alert that is used when an incoming call is received when the silent service mode is not active.

Claims

1. A method for operating a mobile station of a type that is bidirectionally coupled through an RF interface to a network, comprising the steps of:

storing at least one predetermined telephone number in a memory of a mobile station; and

in response to the receipt of an incoming call indication when a silent service mode is active, comparing at least a portion of a telephone number of the calling party to the stored at least one predetermined telephone number and, if at least a portion of the received calling party number matches one of the stored numbers, generating an audible alert to inform the user of the presence of the incoming call, otherwise, if at least the portion of the received calling party number does not match one of the stored numbers, inhibiting the generation of an audible alert.

2. A method as set forth in claim 1, wherein the step of generating an audible alert generates a predetermined audible alert that is different from an audible alert that is used when an incoming call is received when the silent service mode is not active.

3. A mobile station of a type that is bidirectionally coupled through an RF interface to a network, comprising:

a RF receiver for receiving an incoming call indication from the network, the incoming call indication including a calling party telephone number;

a user interface for enabling a user to enter information;

a memory for storing at least one predetermined telephone number that is entered by the user; and

a controller, responsive to the receipt of an incoming call indication when a silent service mode (SSM) is active, for comparing at least a portion of the telephone number of the calling party to the stored at least one predetermined telephone number and, if at least the portion of the received calling party telephone number matches one of the stored numbers, for overriding the active SSM by generating an audible alert to inform the user of the presence of the incoming call, said controller being further responsive to a condition wherein at least the portion of the received calling party telephone number does not match one of the stored numbers, for inhibiting the generation of an audible alert.

4. A mobile station as set forth in claim 3, wherein the controller generates a predetermined audible alert that is different from an audible alert that is used when an incoming call is received when the silent service mode is not active.

5. A mobile station as set forth in claim 3, wherein the memory is comprised of a first memory portion for storing at least one SSM-override telephone number to which at least a portion of the telephone number of a calling party is compared, and is further comprised of a second memory portion for storing at least one speed dialling telephone number, the speed dialling telephone number having an associated flag for indicating, when set, that the speed dialling telephone number is also an SSM-override telephone number.

6. A mobile station as set forth in claim 5, wherein the controller is responsive to the receipt of an incoming call indication, when the silent service mode (SSM) is active, for comparing at least the portion of the telephone number of the calling party to the stored at least one SSM-override telephone number stored in the first memory portion, and also for comparing at least the portion of the telephone number of the calling party to any stored speed-dialing telephone number stored in the second memory whose associated flag is set.

7. A method for operating a mobile station of a type that is coupled through an RF interface to a network, comprising the steps of:

storing at least one Silent Service Mode (SSM override telephone number in a first memory area of a mobile station;

storing at least one other telephone number in a second memory area of the mobile station;

setting a flag associated with at the at least one other telephone number stored in the second memory area for indicating that the associated telephone number is also an SSM override telephone number;

in response to the receipt of an incoming call indication, determining if the SSM is active;

if the SSM is determined to be active, comparing at least a portion of a telephone number of the calling party to the at least one stored SSM override

telephone number stored in the first memory area and, if a match is not found, comparing at least the portion of the telephone number of the calling party to any telephone number stored in the second memory area that has the associated flag set; and

upon an occurrence of at least the portion of the telephone number of the calling party matching one of the compared telephone numbers, generating an audible alert.

8. A method as set forth in claim 7, wherein the step of generating an audible alert generates a predetermined audible alert that is different from an audible alert that is used when an incoming call is received when the SSM is determined not to be active.
