  • Patent number: 8412829
    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.

  • Patent number: 7023813
    Abstract: In a communications system having a plurality of endpoints each including a logical entity and its physical counterpart, a method for managing a pool of multicast addresses. The method including the steps of: generating a pool of available multicast addresses; receiving a request for a multicast address; allocating a multicast address for usage subject to at least a first limitation; monitoring the usage of the allocated multicast address; and reclaiming the allocated multicast address if as a function of the monitoring it is detected that a first condition is met, and causing the allocated multicast address to be placed into the pool of available multicast addresses.

  • Patent number: 6798755
    Abstract: A method for controlling and managing individual directed sessions between at least two endpoints in a communications system. The method including the steps of: intercepting a first message sent from an initiating endpoint via application layer routing to at least one other endpoint 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 to be included in the requested session, and if the requested individual directed session is accepted determining a set of corresponding session parameters; and communicating the state of the requested individual session to the initiating endpoint via application layer routing, and if the requested session is accepted also communicating the state of the session the at least one other endpoint via application layer routing.

  • Patent number: 4893316
    Abstract: A digital radio receiver is described. The digital receiver of the present invention contemplates a digital radio receiver which operates on a received analog signal which has been converted to a digital form after preselection at the output of the antenna. The digital receiver of the present invention comprises a preselector, a high-speed analog-to-digital (A/D) converter, a digitally implemented intermediate-frequency (IF) selectivity section having an output signal at substantially baseband frequencies, and digital signal processor (DSP) circuit 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.

  • Patent number: 4675882
    Abstract: A digital FM demodulator is described. According to the principles of the present invention, a digital FM signal is demodulated by processing sampled input vectors of a quadrature FM digital signal centered approximately zero frequency. The sampled quadrature input vectors are quantized to lie within a predetermined magnitude range. The quantized vectors are coupled to a phase accumulator which generates a current coarse phase value related to input vectors of the quadrature FM signal. The output of the phase accumulator is also coupled to a vector rotation means which rotates the input vector to a predetermined quadrant to determine a fine phase value based on said rotated input signal vector. The fine and coarse values are then summed and output as a composite phase value, and digitally filtered by subtracting the value of the previous composite phase angle sample from the value of the current composite phase angle sample to produce a demodulated message sample.
