Abstract: A wireless communication device performs a method for automatically configuring itself to operate in a wireless communication system managed by a system controller. The wireless device includes an internal memory device containing a first memory identifier associated with a first removable memory device and a first user identifier associated with a user of the wireless device. In one embodiment, the wireless device compares the first memory identifier with a second memory identifier stored in a removable memory device coupled to the wireless device, and transmits a registration message including the second memory identifier to the system controller if the first memory identifier is different than the second memory identifier. The wireless device receives a registration confirmation message including a second user identifier associated with an expected user, and stores the second memory identifier in the internal memory device if the second user identifier matches the first user identifier.

Abstract: A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

Abstract: A mobile communication device (214) in a communication system (200) initiates a call over the fixed equipment network of the communication system to another mobile communication device (216). If the two mobile communication devices are within sufficient proximity to each other, they may switch to a direct mode of communication. (318). The direct mode and network mode of communication are in different frequency bands using different air interface protocols.
