Abstract: A communications system includes a network that is coupled to a number of terminals, at least some of which are capable of audio or other forms of real-time interactive data communications over the network. Each of the terminals includes a network adapter that is capable of detecting a collision with another terminal on the network. If a collision is detected, transmission of a data frame is aborted, and a backoff time delay is selected. The backoff time delay is selected from a group of delay periods that vary at a rate different than exponentially with a number of collisions. The group of one or more delay periods can contain delay periods that increase linearly with the number of collisions, delay periods that increase according to some power of n, where n is the number of collisions, or a delay period that is selected at random based on a predetermined mean backoff delay.

Abstract: A modeling tool that is executable in a system includes a modeling application that is capable of deriving a predicted quality of communications in a represented communications system. A user may create a representation of a target communication system by using icons representing different network components to build the representation in a user interface. Each of the network components is associated with one or more performance parameters, such as packet delay, packet loss, and jitter for packet-based network components. An overall performance parameter, such as an overall packet delay, overall packet loss, and overall jitter may be derived based on the performance parameters for each of the network components. From the overall performance parameters, the expected or predicted performance of the target communications system may be determined by using an E-model in one arrangement.

A plurality of channels is provided with at least one of said plurality of channels being assigned to each of a plurality of terminals. Utilization of the channel resources by the plurality of terminals is monitored and an evaluation is conducted of system needs based on the levels of activity and utilization of channel resources by the terminals.

The resource controller is utilized to adjust the channel resources based on the levels of activity and utilization of resources by the terminals. The adjustment provides active terminals as much resources as required during duration of their activity, subject to resource availability.

Abstract: Methods for switching a mobile between operation in an mobile satellite system mode and a terrestrial wireless mode. When operating in the terrestrial wireless mode, the mobile terminal will initiate an attempt to switch into the MSS mode when it nears the boundary of the coverage area for a terrestrial wireless system to which it is registered. Conversely, a mobile terminal operating in the MSS mode will regularly attempt to switch into the terrestrial wireless mode. For both, a switch between modes is contingent on the mobile terminal identifying a suitable system for registration therewith upon completing the switch between modes. The criteria for identifying a suitable system for selection purposes include the following: (1) the selected system is available, i.e., the mobile terminal is physically located within a coverage area for the selected system; (2) the mobile terminal is compatible with the selected system; and (3) the selected system is willing to accept the mobile terminal.

Abstract: A satellite communication system provides multicast messaging services to subscriber units. Upon receipt of a multicast communication page from a satellite communication system network, a subscriber unit waits for a random delay period and then responds with an acknowledge signal. Based upon the time of receipt of the acknowledge signal, e.g., within one of a plurality of time periods, the satellite communication system network assigns the subscriber unit to one of a plurality of traffic channels. The satellite communication system infrastructure then sends a multicast communication message to the subscriber unit on the assigned traffic channel. The subscriber unit then waits for a random delay period and then responds with an acknowledge signal. The satellite communication system network then receives the acknowledge signal.

Abstract: The mobile station to base station access in a cellular radio system is a classical problem of random multiple access using a shared common channel. Many multiple access protocols have been invented in the past with varied degrees of success in improving the throughput of the multiple access channel. The current invention is a new multiple access protocol which enhances the throughput and reduces the access delay by providing feedback of the detailed status of the access channel from the base station to the mobile station. The feedback mechanism and multiple access protocol are also applicable to other types of radio or wire-based channels.
