Abstract:
A process carried out by a first mobile radio includes detecting a request to transmit group communication media and, responsively, determining, by the first mobile radio, whether a push-to-talk (PTT) key input is in an activated or de-activated state, selecting, by the first mobile radio and as a function of the determined state of the PTT key, one of a first talkgroup on a first wireless network and a second talkgroup on a second wireless network as a target talkgroup to transmit the communication media to, and transmitting, by the first mobile radio via a corresponding one of a first wireless communication interface to the first wireless network and a second wireless communication interface to the second wireless network, the communication media to the selected target talkgroup.
Abstract:
At least one embodiment takes the form of a process carried out by a first radio-network switching system (RNSS). The first RNSS maintains a talkgroup of mobile radios that includes a first mobile radio. The first RNSS receives an add-mobile-radio request from the first mobile radio and responsively sends an add-mobile-radio response to the first mobile radio. The add-mobile-radio response includes an add-mobile-radio authentication token. The first RNSS receives, from a second mobile radio, an add-mobile-radio authentication message that identifies the second mobile radio and that includes the add-mobile-radio authentication token. In response to receiving the add-mobile-radio authentication message from the second mobile radio, the first RNSS adds the identified second mobile radio to the talkgroup.
Abstract:
A method and apparatus for providing images on a camera is provided herein. During operation a server will utilize a vehicle's speed and direction. Images from cameras will then be provided to the vehicle/user based on the vehicle speed and direction. In addition, cameras will have their pan/tilt/zoom (PTZ) adjusted based on the vehicle speed and direction of travel in order to eliminate/prevent overlapping the area that is surveyed by a moving observer.
Abstract:
A mobile radio (MR) transmits short data during an active time division multiple access (TDMA) call in a wireless communication system. The mobile radio receives first communication media (CM) of the active call in a first slot of a first outbound TDMA logical channel (FLC) of an outbound traffic frequency having a slotting ratio n>=2. The MR transmits short data during at least a portion of a second slot of the FLC, pending short data on an inbound logical data channel of an inbound traffic frequency. The MR then receives second CM of the active call in a third slot of the FLC, and receives missed CM of the active call without specifically identifying the missed CM in any request for re-transmission of missed CM, in a first slot of a second outbound TDMA logical channel of the outbound traffic frequency.
Abstract:
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.
Abstract:
A method and apparatus for identifying fingers in contact with a touch screen is provided herein. During operation, a device will attempt to identify a particular finger pattern in contact with the touch screen by identifying fingers in contact with a touch screen. The fingers in contact with the touch screen are preferably identified by determining a fingerprint for each finger in contact with the touch screen. When a fingerprint for all fingers cannot be identified, a fingerprint map will be used to determine those fingers most likely in contact with the touch screen.
Abstract:
During operation a first personal-area network will activate a first camera. The first camera may be manually activated, or triggered by an audio signal. The event that causes the first camera to activate will also cause the personal-area network to send an acoustic signature to other personal-area networks. Personal-area networks that receive the acoustic signature will modify audio triggers so that the acoustic signature can be better distinguished from other noises.
Abstract:
Communication groups are formed based on mobile station location history. The process includes receiving, at a controller device, a group formation request from a requesting device, the request specifying a location and a time window, identifying one or more mobile stations determined to be within a threshold area relative to the location during the time window, and causing a communication group to be created including the identified one or more mobile stations. A further process includes a requesting device configured to identify a location and time window associated with an event, transmit a group formation request specifying the location and the time window and requesting formation of a communication group comprising mobile stations located within a threshold area relative to the location during the time window, and transmit using a communication group identifier provided to the requesting device.
