Abstract

To our mobile users, some calls are more impor- tant than others. Sometimes, it is more critical to get all parties into a call while at other times, the priority is to get the information out to as many users within the shortest time. These different user preferences make up a wide range of call set up cri- teria in the system.

METHOD OF ALLOWING A MOBILE USER TO FLEXlBLk CONTROL THE DURATION OF A CALL REQUEST IN THE SYSTEM CALL QUEUE

BACKGROUND

  To our mobile users, some calls are more impor- tant than others. Sometimes, it is more critical to get all parties into a call while at other times, the priority is to get the information out to as many users within the shortest time. These different user preferences make up a wide range of call set up cri- teria in the system.

PROBLEM

  Motorola's current trunking communication sys- tems provide the mobile users with limited flexibili- ty to select or adjust how long their calls will be queued in the system. Examples are the 'Critical User' and 'Busy Override' features in the SmartZone system. However, these functions still do not offer the mobile users flexibility to change the parameters that control the duration a call stays in the call queue, e.g. on a per call basis.

SOLUTION

  The following scenarios describe a method that allows our mobile users to dynamically control how long their call requests will stay in the system queue and when the call requests will be removed from the queue. Scenarios 1,3, and 4 are already known in SmartZone's critical user and busy override. Scenario 2 is novel and can be incorporated in the existing system as an enhancement feature.

  In the following illustrations, the system (also known as the infrastructure) uses 'the number of Push-To-Talk (FIT) presses' as a mechanism to dis- tinguish the different modes of operations. However, other means, such as menu selection in a man-machine interface or a special knob on the mobile, can also be used.

  Scenario 1 - Call sef!up proceeds only when all critical members of the group call are available at the time the user initiates the call

  The call proceeds IF 'AND ONLY IF all critical members of the group call are available. If any of the critical members is u&available at call set up, the call will be terminated irfmediately by the system. This is a standard SmartZone operation.

1. The mobile user pushes P'IT button once.

2. If all critical members are available, call set up proceeds. Otherwise, the Call is terminated.

  Scenario 2 - Call setup proceeds only when all critical members of the: group call are available within the user-defined w&it time

  The mobile user pre-selects a duration that he/she would like the par&ular call to be queued in the system during call set,,up. The call will then stay in the queue waiting for the critical members of the group call to become avrfilable ONLY UP TO the pre-defined user-selected time duration.

1. The mobile user sel&ts the preferred queued duration via a knob (assliming this is the means to choose the choice of tithe duration). If the user chooses not to change the duration setting, the pre- vious value will be used.
