Abstract: A distributed switching system comprising a call controller, multiple source modules, and multiple destination modules provides circuit switching functionality without using a centralized circuit switch. When a source module of the multiple source modules receives inbound data, the source module broadcasts the data to each destination module of the multiple destination modules via an inbound time slot of multiple inbound time slots. The call controller selects a destination module of the multiple destination modules to process the data and informs the selected destination module of the inbound time slot. The selected destination module then receives the broadcast via the inbound time slot and processes the broadcast data. The distributed switching system further provides for a transfer of data in an outbound direction by allocating an outbound time slot in which the selected destination module embeds tagged data for receipt and forwarding by the source module.

Abstract: A method for dormant data session reactivation may include a packet control function (118) in a radio access network (104) receiving a first data packet (150) having a source IP address (152), where the first data packet has a destination IP address (152) addressed to reactivate a dormant mobile station (102) coupled to the radio access network. The packet control function may receive a plurality of subsequent data packets (160) having the source IP address, where each of the plurality of subsequent data packets has a subsequent destination IP address (162, 164, 166) and a corresponding time stamp (163, 165, 167). For each of the subsequent destination IP addresses that are substantially sequential, evaluating an absolute value of a slope (270) of the difference between the subsequent destination IP addresses that are substantially sequential over a difference in the corresponding time stamps.

Abstract: A method of selective dormant data session reactivation in a radio access network includes calculating an activation rate threshold as a function of a first plurality of packets received over a first time interval, where the first plurality of packets are coupled to reactivate at least one dormant mobile station. The second plurality of packets received in a second time interval are buffered, where each of the second plurality of packets has a destination IP address to reactivate the at least one dormant mobile station. An arrival rate of the second plurality of packets in the second time interval is compared to the activation rate threshold.

Abstract: A method and system for distributing a plurality of data processing units (116, 118, 120, 122, 124, 126, 128, 130 and 132) in a communication network (100) is provided. The communication network comprises a plurality of manager data processing units (104, 106 and 108) for serving the plurality of data processing units. The method includes detecting (304) a failure at a manager data processing unit of the plurality of manager data processing units. Further, the method includes distributing (306) the plurality of data processing units to remaining manager data processing units of the plurality of manager data processing units.

Abstract: A method, information processing system, and wireless communication system for optimizing neighbor lists. A set of target communication sectors (240, 242) are identified within a given distance threshold from at least one of the base station (106) and a wireless device (134) currently registered with the base station (106). At least one target communication sector (240) is randomly selected from the set of communication sectors (240, 242). An identifier associated with the at least one randomly selected target communication sector (240) is inserted into a base station neighbor list (138). The base station neighbor list (138) is prioritized based on a set of call detail records associated with the at least one randomly selected target communication sector (240).

Abstract: A method for sharing a total licensed pool between network elements is disclosed. In the method, each of the network elements has a fixed available capacity. In a first step, an offered load capacity limit based on the total licensed pool and the available capacity is determined. Next, each of the network elements communicates a message comprising the offered load capacity limit. Then, each of the network elements monitor for messages. If a message is not received from one of the network elements, the network element that is not communicating is considered a failed network element. Upon detection of the failed network element, the offered load capacity of the failed network element is redistributed.

Abstract: Line terminal equipment (30, 35) transmits health and status information (66, 68) to bearer payload processors (50-N). Each bearer payload processor (50-N) concatenates (96) the health and status information of the line terminal equipment. Each bearer payload processor transmits the concatenated health and status information including bearer traffic to each of the line terminal equipment (30, 35). Both the line terminal equipment and bearer payload processors compare (98, 100) the health and status information.

Abstract: An automatic protection arrangement for a communication system (100) provides a working line terminal equipment (300 and a link (1A) for transmitting bearer traffic from a number of bearer payload processors (50-N) to a switching center (10). The arrangement also has a protection line terminal equipment (35) and link (2A) coupled to the switching center (10). For detected faults, an instantaneous switch over occurs of the bearer traffic of the bearer payload processors (50-N) from the working line terminal equipment (30) to the protection line terminal equipment (35).

Abstract: In a satellite communication system, beamforming is performed at baseband frequencies forming only beams which convey information. A received signal is applied to a downconverter (FIG. 1, 30), followed by a channelizer (50), and digital beamformer (60). The order of operations being reversed in order to generate a transmit beam. By performing the beamforming at baseband, the system can be allowed to form only those beams which convey information between a communications node and a subscriber. As a result, the system provides communication services to subscribers in a more cost-effective manner.

Abstract: A method and apparatus for efficiently interconnecting a large number of high frequency high bandwidth signals includes two interface plates (100, 200), each having two substantially coplanar faces, a mating face (110, 210) and a non-mating face (120, 220). Each interface plate has waveguides (116, 216) disposed between the coplanar faces such that when the mating faces of the interface plates are brought together, a plurality of waveguide connections are made. An energy absorbing gasket (300) having a hole pattern matching the waveguide pattern is disposed between the mating faces of the interface plates so that reflections caused by misalignment and non-coplanarity of faces can be reduced.
