A dispatch call setup method selects (101) either a forced dispatch call (105) or an invite dispatch call (103). The originating unit (20) of the dispatch call may select either option. Depending on how the required target users (30, 40) respond, the originating terminal has the option to complete the call ( 119). The terminating unit may accept, reject or convert the forced dispatch call (127). Further, the target may establish preset preferences which accept, reject or allow user controls for an invite dispatch call (139).

The invention claimed is: 1. A dispatch call setup method for a dispatch call between an originating unit and at least one target unit via a communication network, the dispatch call setup method comprising the steps of: sending an dispatch call message to the at least one target unit, the dispatch call message having a selected dispatch call setup type selected between a forced message and an invited message at the originating unit; determining whether a response from the at least one target unit is sufficient for the dispatch call; and if the response from the at least one target unit is sufficient completing the dispatch call between the originating unit and the at least one target unit. 2. The method for dispatch call setup as claimed in claim 1, wherein: the dispatch call message including a selected dispatch call setup type of an invite message; and if the response of the at least one target unit is insufficient, there is further included steps of: ignoring the response of the at least one target unit; and ending the call. 3. The method for dispatch call setup as claimed in claim 2, wherein if the at least one target unit accepted the invite message, there is further included steps of: completing the dispatch call between the originating unit and the at least one target unit via the communication network; and sending bearer traffic. 4. The method for dispatch call setup as claimed in claim 3, wherein there is further included a step of receiving at least one response from the at least one target unit after the step of sending the invite message. 5. The method for dispatch call setup as claimed in claim 4, wherein there is further included a step of determining the selected dispatch call setup type. 6. The method for dispatch call setup as claimed in claim 5, wherein if the selected dispatch call setup type is a type for an invite message, the steps of: sending an call start message; receiving a response from the at least one target unit; if the response from the at least one target unit is sufficient, completing the dispatch call. 7. The method for dispatch call setup as claimed in claim 5, wherein if the selected dispatch call setup type is a type for a forced message, there is further included a step of sending a forced message to the at least one target unit. 8. The method for dispatch call setup as claimed in claim 7, wherein after the step of sending the forced message, there is further included the steps of: determining whether the originating unit is concerned whether the at least one target unit participates in a forced dispatch call; and if the originating unit is not concerned, there is further included steps of completing the dispatch call and sending bearer traffic. 9. The method for dispatch call setup as claimed in claim 8, wherein if the originating unit is concerned, there is further included steps of: determining whether a sufficient number of at least one target units accept the forced type of dispatch call; if a sufficient number have accepted, there is further included a step of traffic; and if an insufficient number have accepted, there is further included a step of ending the dispatch call. 10. The method for dispatch call setup for a dispatch call between an originating unit and a target unit-via a communication network, the method comprising the steps of: receiving by the target unit an invite message for a dispatch call, the dispatch call message having a selected dispatch call setup type selected between a forced message and an invited message at the originating unit; determining a preset preference of the target unit for the selected dispatch call setup type; determining whether to accept the invite message based upon the preset preference; and if the invite message is accepted, sending an accept message to the originating unit. 11. The method for dispatch call setup as claimed in claim 10, wherein if it is determined to reject the invite message, there is further included a step of sending a reject message to the originating unit. 12. The method for dispatch call setup as claimed in claim 10, wherein if the preset preference is for a user control, there is further included a step of notifying by the target unit a user of an incoming invite dispatch call. 13. The method for dispatch call setup as claimed in claim 10, wherein if the preset preference is for automatically accepting, there is further included steps of: sending an accept response message to the originating unit; and accepting bearer traffic. 14. The method for dispatch call setup as claimed in claim 10, wherein if the preset preference is for automatically rejecting the invite message, there is further included steps of: sending by the target unit a reject message to the originating unit; and inhibiting acceptance of bearer traffic. 15. The method for dispatch call setup as claimed in claim 14, wherein after the step of sending a response message to the originating unit, there is further included a step of accepting bearer traffic. 16. A method for dispatch call setup for a dispatch call between an originating unit and a target unit via a communication network, the method including the steps of: determining whether a dispatch call method of the originating unit is a forced dispatch call; determining by the target unit if a preset preference is to convert the forced dispatch call; if the preset preference is to convert, converting the forced dispatch call to an invite dispatch call; and if the invite dispatch call is accepted, receiving bearer traffic. 17. The method for dispatch call setup as claimed in claim 16, wherein the step of converting further includes the step of displaying by the target unit the invite dispatch call to a target user. 18. The method for dispatch call setup as claimed in claim 16, wherein there is further included steps of: determining whether the preset preference of the target unit is to automatically reject the forced dispatch call; if the preset preference is to automatically reject, sending by the target unit a reject message to the originating unit; and inhibiting bearer traffic by the target unit. 19. The method for dispatch call setup as claimed in claim 16, wherein if it is determined that the preset preference is to automatically accept the forced dispatch call, there is further included a step of automatically accepting bearer traffic. 20. The method for dispatch call setup as claimed in claim 16, wherein there is further included a step of dynamically selecting the preset preference. 21. The method for dispatch call setup as claimed in claim 16, wherein prior to the step of receiving bearer traffic there is further included a step of sending an accept message to the originating unit.
