Abstract: A method and apparatus for re-routing a call a when utilizing a collaborative mode of operation is provided herein. During operation, when a radio is operating in a collaborative mode, a battery level of the smart device will be monitored by the radio. If the associated smart device's battery is below a predefined threshold, the radio will be connected to a new talk-group via a standard narrowband network. As a consequence, each outgoing (or incoming) call from the radio over the new talkgroup on the narrowband network will be re-routed to the broadband network via the narrowband network (without utilizing the smart phone).

Abstract: Method and apparatus for associating a subscriber identity module to a group of mobile communications devices is provided. One embodiment provides a method including receiving the hashed value from the SIM card and decrypting, using the trusted electronic processor, the hashed value based on a second key stored on the mobile communications device to generate a response. The method also includes sending, using the trusted electronic processor, the response to the SIM card and receiving, at the trusted electronic processor, an acknowledgement from the SIM card indicating that the response matches an expected response.
