Mobile station and method of use in radio communications
First Claim
1. A mobile station comprising:
- a processor,a memory coupled to the processor and storing therein an instruction set,a transmitter and a receiver both coupled to the processor and being adapted to operate in accordance with a communications protocol using Group Call Access Permission (GCAP) and Help Request Level (HRL) fields stored in the memory,a user interface including a display coupled to the processor and responsive to the instruction set stored in the memory for selecting, setting and displaying the GCAP and HRL fields,a GCAP extractor and an HRL extractor for extracting values of GCAP and HRL fields of an incoming message, andrespective comparators coupled to the GCAP extractor and to the HRL extractor for comparing the values of the respective fields extracted thereby with values stored in the memory;
said processor being responsive to respective outputs of the comparators for determining whether to join an incoming call.

Abstract
A method for setting up a group call within a dispatch radio communication system is disclosed. Additional stations which are not programmed to respond to a transmitted group identification code (GIC) are enabled to join the call. The method comprises steps carried out by a service provider of (a) providing first and second additional fields in a set-up message, the first additional field carrying a Group Call Access Permission (GCAP) value and the second additional field carrying a Help Request Level (HRL) value, (b) enabling a call initiator to select a GCAP value, according to a range of stations the call initiator wishes to reach, and a HRL value, according to an assigned call priority, for transmission alongside the GIC in the step (a) fields, and (c) enabling any station that receives a set-up message to determine whether to join the call based on the GCAP and HRL values.

3. A method for setting up a group call within a dispatch radio communication system, using a broadcast set-up message that includes a group identification code (GIC), whereby additional stations, which are not programmed to respond to the transmitted GIC, are enabled to join the call, the method comprising the steps, all carried out by a service provider:
-
(a) providing at least first and second additional fields in the set-up message, the first additional field carrying a Group Call Access Permission (GCAP) value and the second additional field carrying a Help Request Level (HRL) value, (b) enabling a call initiator to select a GCAP value, according to a range of stations he wishes to reach, and a HRL value, according to a priority assigned to the call, for transmission alongside the group identification code in the respective fields of step (a), and (c) enabling any station that receives a group call set-up message to determine whether to join the call, on the basis of the values of the GCAP and the HRL fields. - View Dependent Claims (4, 5, 6, 7, 8, 9)

10. A method for setting up a group call within a dispatch radio communication system, using a broadcast set-up massage that includes a group identification code (GIC), whereby additional stations, which are not programmed to respond to the transmitted GIC, are enabled to join the call, the method a comprising the steps, all carried out by a call initiator:
-
(1) selecting a Group Call Access Permission (GCAP) value, according to a range of receiving stations the call initiator wishes to reach, and a Help Request Level (HRL) value, according to a priority assigned to the call, (2) transmitting a set-up message including the group identification code and at least a first additional field carrying said Group Call Access Permission (GCAP) value and a second additional field carrying said Help Request Level (HRL) value, and (3) receiving from a responding station a group call set-up message having GCAP and HRL fields and determining whether to allow the responding station to join the call, on the basis of the values of the GCAP and the HRL fields. - View Dependent Claims (11, 13, 14, 15)

16. A program storage device readable by machine, embodying a program of instructions executable by the machine to perform method steps for setting up a group call within a dispatch radio communication system, using a broadcast setup message that includes a group identification code (GIC), whereby additional stations, which are not programmed to respond to the transmitted GIC, are enabled to join the call, the method comprising the steps:
-
(a) providing at least fast and second additional fields in the setup message, the first additional field carrying a Group Call Access Permission (GCAP) value and the second additional field carrying a Help Request Level (HRL) value, (b) enabling a call initiator to select a GCAP value, according to stations he wishes to reach, and a HRL value, according to a priority assigned to the call, for transmission alongside the group identification code in the respective fields of step (a), and (c) enabling any station that receives a group call setup message to determine whether to join the call, on the basis of the values of the GCAP and the HRL fields.
