    Abstract: A method for controlling and managing individual directed sessions between a t least two endpoints (240, 242) in a communications system. The method including the steps of: intercepting a first message sent from an initiating endpoint (240) via application layer routing to at least one other endpoint (242) requesting an individual directed session; communicating the requested individual directed session to a service entity for determining the state of the session as a function of communication system resources and capabilities and resources of the endpoints (240, 242) to the be included in the requeste d session, if accepted, determining a set of corresponding session parameters; and communicating the session to the initiating endpoint (240) also communicating the state of the session the at least one other endpoint (246) .

    Abstract: In a communications system having at least one service entity and a plurality of endpoints each including a logical entity and a terminal, a method facilitates a session between at least two of the endpoints in the system. The method includes: receiving a first message having information that includes a request for a session between a first endpoint that includes a non-dispatch terminal and at least one other endpoint; detecting that the first endpoint includes a non-dispatch terminal as a function of the first endpoint being unable to perform at least one function; and causing the at least one function to be performed on behalf of the first endpoint by the at least one service entity to facilitate the session between the first endpoint and the at least one other endpoint.

    Abstract: A method and system for group communications between a plurality of endpoint s (102, 106, 108 etc.) in a system (100) is described. The method includes the steps of: a) receiving at a group entity (104) from an initiating endpoint (102), using a transactional protocol, a first message requesting a session between a plurality of endpoints (106, 108 etc.) affiliated with a group tha t correlates to the group entity (104); b) causing the session to be accepted; c) causing the presence of the session to be communicated, using a broadcast protocol, to the plurality of endpoints (106, 108 etc.) affiliated with the group; and d) communicating from the group entity (104) to the initiating endpoint (102), using the transactional protocol, the acceptance of the session.

    Abstract: DIGITAL RADIO FREQUENCY RECEIVER A digital radio receiver is described. The digital receiver (100) of the present invention contemplates a digital radio receiver which operates on a received analog signal which has been converter to a digital form after preselection at the output of the antenna. The digital receiver (100) of the present invention comprises a preselector (106), a high-speed analog-to-digital (A/D) converter (108), a digitally implemented intermediate-frequency (IF) selectivity section (110) having an output signal at substantially baseband frequencies, and digital signal processor (DSP)circuit (120) performing demodulation and audio filtering. The radio architecture of the present invention is programmably adaptable to virtually every known modulation scheme and is particularly suitable for implementation on integrated circuits.

    Abstract: A method and system for group communications is described. The system includes a plurality of endpoints and at least one group entity that receives from an initiating endpoint, using a transactional protocol, a first message requesting an initiation of a session between a plurality of endpoints affiliated with a group that correlates to the group entity. The group entity further: causes the session to be accepted in order to start the session; upon the acceptance and start of the session causes the presence of the session to be communicated, using a broadcast protocol, to the plurality of endpoints affiliated with the group; and communicates to the initiating endpoint, using the transactional protocol, the acceptance of the session.

    Abstract: A method for determining at least one set of communications capabilities that are common to physical counterparts of endpoints (240, 242) affiliated with a group in a communications system having a plurality of endpoints, each comprising a logical entity and its physical counterpart, the method comprises retrieving (504) a list of endpoints affiliated with a group, retrieving (506) communications capabilities of a physical counterpart of each affiliated endpoint, and determining (508) whether at least one set of group communication capabilities can be generated that includes communications capabilities that are common to the physical counterparts of at least a subset of the affiliated endpoints, and if so generating (510) the at least one set of group communications capabilities.
