The dual mode radio can be a first modem operating on a CDMA network and a second modem operating on an iDEN network.

Abstract: A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.

The method and system include the steps of filtering (402) a wideband voice signal to produce a first filtered signal (301) and a second filtered signal (331), vocoding (404) the first filtered signal to produce a narrowband vocoded signal (130), compensating (406) the second filtered signal for time alignment with the narrowband vocoded signal, and adding (335) the narrowband vocoded signal with the second filtered signal to produce a wideband vocoded signal (250). One or more features from the wideband vocoded signal can be extracted to create a wideband feature vector (147) for storage in a wideband vocoded speech database (220).

The method can include identifying (402) mobile devices (104) in an area (910), discovering (404) sound production capabilities and sound monitoring capabilities, identifying (406) a relative location of devices in the area, assessing room acoustics (706), and networking the (408) devices for creating a surround sound based on the relative location, sound capabilities, and room acoustics.

Abstract: The invention concerns a method (300) and system (100) for interrupting a dispatch call. The method can be practiced in a dispatch communications system (100) having at least a first communications channel (162) for carrying voice traffic and a second communications channel (164) for carrying communications-enabling information. The method includes the steps of assigning (312) the first communications channel to at least a first caller (133) and a second caller (135) to permit the first and second callers to engage in a dispatch call and as the first caller has control over the first communications channel, transmitting (314) an interrupt message (505) over the second communications channel to inform the first caller of an interrupt status of the second caller. The transmitting step is performed without terminating the dispatch call.

The processor can analyze (93) a user's background view for areas suited for display of information in an analysis, and unobtrusively present (94) information within the user's field of view on the wearable display based on the context of use and the analysis. The processor can also determine (95) the type of information to unobtrusively present based on the context. The processor can optionally detect (92) the context of use by analyzing or recognizing a tool or an instrument used by a user of the wearable display.

Abstract: A digital network based communications system that establishes communications sessions to communicate via a simulated circuit-switch environment. Exemplary embodiments communicate between a first communications station (104) and a second communications station (106) using Voice over Internet Protocol (VOIP) techniques. Calls are setup (700), maintained and torn down (800) using Session Initiation Protocol and Session Description Protocol messages. Call modes are able to be changed between duplex and simplex without disconnection. Duplex calls are also able to be interrupted with a request for a simplex call. A receiver (104) engaged in a duplex call can receive a request for a simplex call, accept the simplex call or send a response message, and then resume the duplex call, all while maintaining the duplex call data communications session.

Abstract: A peer to peer messaging protocol allows for messaging using a variety of media and for changing the media during a messaging session. The protocol requires far less code space to implement over existing messaging protocols, such as session initiation protocol, and real time transport protocol. The protocol employs a capability exchange (602) for establishing the media capabilities of the respective peer devices as both a request and the final negotiation. The capability exchange messages use a common header (103) that is also used in subsequent data transmissions carrying the actual message content.
