METHODS AND SYSTEMS FOR JOINING A SUB-TALKGROUP OF A FIRST TALKGROUP

摘要

A process carried out by a first mobile radio for joining a sub-talkgroup of a first talkgroup includes receiving, via a provisioning process or via an infrastructure wireless communication interface from an infrastructure radio access network (RAN) while within wireless communication range of the RAN, a talkgroup-specific security token associated with and shared by all group mobile radios in a first talkgroup to which the first mobile radio is subscribed via the RAN. The first mobile radio then detects, via a short-range wireless communication interface, a second mobile radio, and authenticates, the second mobile radio using the talkgroup-specific security token. If the authentication is successful, the first mobile radio adds an identity of the second mobile radio to a sub-talkgroup set of mobile radios of the first talkgroup.

主权项

1. A first mobile radio that is a member of a first talkgroup, the first mobile radio comprising:
an infrastructure wireless communication interface for communicating with an infrastructure radio access network (RAN); a short-range wireless communication interface for communicating with an ad-hoc network; a processor; and data storage containing instructions executable by the processor for causing the first mobile radio to carry out a set of functions, the set of functions comprising:
receiving, via a provisioning process or via the infrastructure wireless communication interface from the RAN while within wireless communication range of the RAN, a talkgroup-specific security token associated with and shared by all group mobile radios in a first talkgroup to which the first mobile radio is subscribed via the RAN;detecting, via the short-range wireless communication interface, a second mobile radio; andauthenticating the second mobile radio using the talkgroup-specific security token and, if successful, adding an identity of the second mobile radio to a sub-talkgroup set of mobile radios of the first talkgroup.
