A fiber-optic communications interface () and method of operation that operates with a paired fiber-optic communications interface () in a redundant communications termination point (). The fiber-optic communications interface () has a paired card interface () that exchanges at least a first subset of status data between a local bearer processor () and a paired bearer processor () located within a different card cage (). The local bearer processor () processes bearer data channels communicating with a remote site () through a remote site fiber-optic line (). A local data interface () exchanges data contained in the bearer data channels between the local bearer processor () and a local user data network (). The local data interface () also exchanges at least a second subset of the status data with the paired bearer processor () through the local user data network ().

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.

A method and electronic device () for processing incoming packets in a communication network () is disclosed. The method includes filtering () incoming packets in real time by using a recent offender list (). The method also includes classifying () the incoming packets as offending packets and non-offending packets in non-real time.

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. If the arrival rate exceeds the activation rate threshold, the second plurality of packets may be separated into a plurality of source IP groups according to their respective source IP addresses, and progressively discarding in descending order one of the plurality of source IP groups having a highest number of the second plurality of packets until the arrival rate is below the activation rate threshold.

A mobile station () is coupled to an external network () or to a media gateway (). A network resource allocation manager () pre-establishes a communication network () connection of network nodes (-). This plurality of communication nodes is assigned () as a complete unit instead of piecemeal sequentially. Based upon communication network node resources and network operator input, a number of the communication nodes or speculative contexts are pre-established ().

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.

Line terminal equipment () transmits health and status information () to bearer payload processors (-N). Each bearer payload processor (-N) concatenates () 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 (). Both the line terminal equipment and bearer payload processors compare () the health and status information.

The packets () are stored in a candidate packet buffer () as candidate packets () in accordance with the established transmission priority (). The system () further includes an interference resolver () that executes an interference resolution process () to concurrently consider transmission resource availability, spatial separation, and temporal separation variables when scheduling the candidate packets () for transmission from the communication platform ().

A method and apparatus for steering beams modulated from a mobile platform in a manner that reduces overall platform payload processing, and therefore payload weight and power requirements. According to the present invention, a beam steering data calculator ( ) generates a table of beam steering data sets ( ), with each data set corresponding to a specific beam-pointing angle mapped to a corresponding cell on the surface of the earth. A data set that corresponds to a received downlink cell address ( ) is read out from the table and mapped to the downlink address, and an output angle of a modulated vehicle beam ( ) that transmits a data packet to the cell address is corrected to correspond to the beam-pointing angle of the read-out data set. The generated table of beam steering data sets ( ) is then re-used for an application-specific quantization time for mapping subsequently-received downlink addresses with beam steering data sets, thereby obviating the need to provide real-time updates of data sets on a packet transmit interval basis. In addition, the present invention is capable of compensating for numerous other causes of beam-pointing error, thereby improving overall beam-pointing accuracy.

A data processing system (20) schedules the allocation of a common bus (26), used by multiple service requesters (32). The system (20) creates a plurality of service request levels (44) and assigns each service requester (32) to one of the plurality of request levels (44). Services of the common bus (26) are provided to all service requesters (32) assigned to a first service request level (44) for each instance of providing service to one of the service requesters (32) assigned to a second service request level (44).
