APPARATUS AND METHOD FOR INCORPORATING MULTIPLE TALK GROUPS IN A SINGLE CALL

摘要

A radio receives a call including a call include bitmask (CIB). The radio retrieves a call include list (CIL) that, for each bit position in the CIB, maps the bit position to one of a radio identifier, a talk group identifier, and a sub-CIL. The radio determines that one bit position in the CIB is set to a value indicating that a radio associated with a radio identifier mapped to the bit position in the CIB via the CIL or to a talk group identifier mapped to the bit position in the CIB via the CIL are to be included in the call. The radio matches its identifier to the radio identifier mapped to the bit position or matches a talk group to which it subscribes to the talk group identifier mapped to the at least one bit position and unmutes the call.

主权项

1. A method comprising:
receiving, by a first receiving radio, a call including one of a header and an embedded control signaling, the one of the header and the embedded control signaling including a call include bitmask (CIB); retrieving, by the first receiving radio, a call include list, CIL, that, for each bit position in the CIB, maps the bit position to one of a radio identifier, a talk group identifier, and a sub-CIL, the sub-CIL including a further listing of two or more of radio identifiers or talk group identifiers; determining, by the first receiving radio, that at least one bit position in the CIB is set to a value indicating that receiving radios associated with one or more radio identifiers mapped to the at least one bit position in the CIB via the CIL or associated with the one or more talk group identifiers mapped to the at least one bit position in the CIB via the CIL are to be included in the call; matching, by the first receiving radio, a radio identifier of the first receiving radio to the one or more radio identifiers mapped to the at least one bit position in the CIB via the CIL or matching a talk group to which the first receiving radio is subscribed to the one or more talk group identifiers mapped to the at least one bit position in the CIB via the CIL; and responsive to the matching, the first receiving radio unmuting the call.
