Abstract: A system capable of detecting data within user application streams to manage or control the chains. For example, the system can receive bandwidth information from the application, and based on that information, determine a level of network traffic caused by the application. Such bandwidth information can include any one or more of subscription information, information provided by an application running on a user device, information provided by an application function, and a detected application type. Based on the bandwidth information, the system can either determine a service chain route for the stream, or determine how to bill for the traffic caused by the application. For example, such determinations may be conducted dynamically based on previously determined if/then rules established by a user of the system.

Abstract: A common clock shared by two or more nodes within a network used for time-synchronization. The nodes communicate via a packetized data transmission. Each data packet has a header with a value. The clock includes a first timing portion that includes at least two data packets where the value is constant for each data packet, and a second timing portion that includes at least two data packets where the value is constant for each data packet but different from the value of the data packets in the first timing portion. Alternatively, the clock includes a first timing portion that includes at least two data packets where the value changes with each data packet, and one or more subsequent timing portions each including at least two data packets where the value is constant for each data packet within a subsequent timing portion but changes with each of the subsequent timing portions.

Abstract: A communication network (10) utilized for providing communications between a first party and a second party includes a surveillance server (26) within a core network (10) to provide communication surveillance capability. The core network (10) may be a packet data network, and the surveillance server (26) is operable responsive to trigger information to establish communications surveillance. Communication surveillance may be established by creating duplicate bearer packets of those data packets carrying the communicated data between the parties, creating duplicate control packets of those data packets carrying in-band or out-of-band call control information between the parties and within the packet data network, and/or various combinations thereof. The duplicate bearer packets and the duplicate control packets are routed to appropriate authorized law enforcement agencies for providing surveillance.

Abstract: In accordance with the preferred embodiments of the present invention, a communication network (110) and a method (600) for enabling a mobile feature on a land line element are described herein. The communication network (110) generally includes a home subscriber server (240), a services client element (220), and a database translation feature server (230). The home subscriber server (240) being operable to provide mobile feature information. The services client element (220) is coupled for communication with the home subscriber server (240) to retrieve mobile feature information based on a registration associated with a subscriber. The database translation feature server (230) is coupled for communication with the services client element (220) to receive the mobile feature information. Furthermore, the database translation feature server (230) is operable to transmit the mobile feature information to a land line element (250).

Abstract: A first data stream (26) requested by a first client (1) is received at a router (16). A second data stream (24) requested by a second client (2) is also received at the router (16). The router (16) determines that the first data stream (26) and the second data stream (24) are identical. The router (16) multicasts the first data stream (26) and the second data stream (24) into a single multicast data stream (28). The single multicast data stream (28) is transmitted to the first client (1) and to the second client (2).

Abstract: The present invention provides a subscriber device (10), method (1000, 1500), wireless router (30), and communication system (100). The communication system (100) includes at least one subscriber device (10) having a message generator (1612) for generating a message which includes an indicator of a receive/transmit switching time, and the wireless router (30) for communicating with at least one subscriber device, the wireless router having a scheduler (902), optimizer (904), and an allocation map generator (906), wherein the wireless router (30) prepares an efficient and optimized channel allocation map for transmission to the subscriber device (10) taking into account the indicator of the receive/transmit switching time for the subscriber device (10) and wherein the map indicates at least one allocated transmit time, in a form of a block, having a beginning and an end, for transmission by the subscriber device following a receive time.

Abstract: An Internet Protocol telephone system and method uses a telephone (26) to place and receive voice over Internet Protocol (VoIP)-based telephone calls and public switched telephone network (PSTN)-based telephone calls. An off-hook condition with the telephone (26) is detected and a sequence of signals generated by the telephone (26) is received. At least a first signal generated by the telephone (26) is buffered while the system attempts to detect a predetermined signal that signifies a VoIP-based call. Upon detection of the predetermined signal, the system intercepts subsequent signals in the sequence, absent the at least first signal that was buffered, and places the VoIP-based call via an internet (12). Otherwise, the system places the PSTN-based call via a PSTN (16).

Abstract: A media switching apparatus automatically switches a user device between wired and wireless service mediums of communications networks. The switching apparatus includes a protocol stack having a network layer, a logical link control, a first set of lower layers specific to a wired service medium and a second set of lower layers specific to a wireless service medium. A selector is responsive to the availability of a wired service medium for selecting the first set of lower layers and is further responsive to the non-availability of a wired service medium and the availability of a wireless service medium for selecting the second set of lower layers.

Abstract: A cable telephony system (100) including a plurality of subscriber units (104) connected to a head-end (102) by a cable distribution network (106) in which upstream and downstream data transmissions are sent between subscribers (104) and head-end (102). Both shared and unshared connections are supported within cable telephony system (100). Transmission between a subscriber (104) and head-end (102) may involve both a shared and unshared connection in which unshared connections are employed to provide a higher quality of service when the shared connection is unable to do so.
