摘要： A method and apparatus for operating a portable radio communication device is provided. The portable radio communication device receives communications on a primary channel and a secondary channel during a dual-watch mode of operation. The portable radio communication device determines whether the portable radio communication device is proximate to a subject. The portable radio communication device suppresses audio from communications of one of the two channels and plays audio from communications of the other channel when the portable communication device is proximate to the subject. Additionally, the portable radio communication device allows transmission to occur only over the channel in which communication is not suppressed when the portable communication device is proximate to the subject.

摘要： A method and apparatus for simulcasting within a communication system is provided herein. During operation, each base site will be equipped with a plurality of radios capable of transmitting on various frequencies. Base sites within the communication system will be capable of communicating on a predetermined number of channels, which may differ among base sites. A number of channels will be shared by the base sites. When a simulcast is desired, the participants are located, and a common channel is determined for communication. Thus, call participant location information is used to determine the best channel to use to meet the group's coverage needs.

摘要： A method and system for direct mode operation (DMO) of a talkgroup enables device to device (D2D) DMO operation leveraged from a Land Mobile Radio (LMR) system. The method includes scanning at a radio receiver a defined radio frequency spectrum; receiving at the radio receiver in the defined radio frequency spectrum a wake-up signal; identifying a talkgroup identifier in the wake-up signal, wherein the talkgroup identifier corresponds to a talkgroup being monitored by the radio receiver; in response to identifying the talkgroup identifier, decoding code sequences included in the wake-up signal; identifying in at least one of the code sequences both a center frequency and a transmission bandwidth of the DMO transmission; and tuning the radio receiver to receive the DMO transmission at the center frequency and transmission bandwidth.

摘要： A method and system includes the ability for individuals to set up an ad hoc digital and voice network easily and rapidly to allow users to coordinate their activities by eliminating the need for pre-entry of data into a web or identifying others by name, phone numbers or email. This method is especially useful for police, fire fighters, military, first responders or other emergency situations for coordinating different organizations at the scene of a disaster to elevate conventional communication problems either up and down the chain of command or cross communication between different emergency units. The method and system provides that the users are only required to enter a specific Server IP address and an ad hoc event name, a password and perhaps the name of the particular unit.

摘要： A multivoice radio system allows users to speak and listen, at the same time, to others using multivoice radios without using a base station. Several embodiments of the present invention are directed toward combining a multivoice radio with push-to-talk (PTT), long-range radio. Other embodiments combine two or more multivoice systems and/or use an extender to increase a distance that multivoice radios can communicate with each other. Combining multivoice systems, in some embodiments, creates a voice and/or data mesh network. Switch-to-talk (STT) functionality can be added to systems to increase a number of users and promote radio discipline. Additionally, a combined in-ear microphone and speaker is disclosed. Further embodiments are directed to combining duplex radios, such as mobile phones, to multivoice systems, and/or PTT systems.

摘要： A first reception unit receives a sound signal destined to a second terminal device in a second communication system supporting one way communication from a first terminal device in a first communication system supporting two way communication. A first transmission unit transmits the sound signal received in the first reception unit to the second terminal device. A second reception unit receives a sound signal destined to the first terminal device from the second terminal device. A second transmission unit transmits the sound signal received in the second reception unit to the first terminal device. A storage unit stores the sound signal received in the first reception unit if the second transmission unit is transmitting the sound signal received in the second reception unit. The first transmission unit transmits the sound signal stored in the storage unit when reception of the sound signal in the second reception unit is completed.

摘要： Dynamic group formation in a wireless radio communication system including a plurality of subscriber units is implemented using variable distance parameters. First, a request for a new group call relative to a defined location is received at a controller from a requesting device. A current location of each of a plurality of potential responding second subscriber units is determined. A maximum response distance associated with each of the second subscriber units is determined as a function of a stored mode of transport associated with each of the second subscriber units. A group is formed including second subscriber units having current locations that fall within the maximum response distance relative to the defined location associated with that second subscriber unit. Audio or data transmitted by the requesting device is then caused to be provided to the second subscriber units in the formed group.

摘要： An instruction to enter a scanning mode may be received at a communication device. The communication device may participate in several talkgroups. A determination may be made that at least one of the talkgroups is active. In response, the communication device may be set to a first active talkgroup. A determination may be made that a predetermined time has passed since the communication device was set to the first active talkgroup. In response, a determination also may be made that at least a second one of the talkgroups, other than the first active talkgroup, is active. In response, the communication device may be set to the second active talkgroup.
