Abstract: A frame for multiplexing multi-traffic frames of layers on a same carrier wave and an apparatus thereof is constituted by an overhead and a payload. The overhead is constituted by: a data length identifier indicating a frame or a payload length; a flow identifier indicating an attribute of the frame; and a frame header overhead error check (FHEC) storing a result obtained by converting bytes from the head to a specified M-th byte of the frame into a numerical value of n bytes according to a certain coding method. A maximum length of the payload is computed from the data length identifier of the overhead. In the payload, traffic for the layers 1 to 3 can be accommodated. Even if the ATM cell and the frame are multiplexed, since coding methods for the FHEC and the HEC are different, the ATM cell and the frame can be extracted individually.

Abstract: In a multi-layer telecommunications system which includes an application layer and a transport layer, differing transport technologies are interworked without terminating the application layer signaling or without involving a technology interworking in the control plane of the application layer (e.g., without interworking in the application signaling). In various illustrated embodiments, the application layer is a radio network layer of a wireless telecommunications system. In at least some embodiments of the present invention a transport layer interworking function is situated on an interface between two nodes of the radio access network (RAN). The interworking function can be located in a separate node which may be a node having both ATM and internet protocol (IP) interfaces. There are numerous modes of implementing the interworking of the present invention, regardless of which interface is affected (e.g., an Iur interface, an Iu interface, or an Iub interface).

The signaling control agent sends queries to and receives responses from the session manager to control the operation of the wireless access gateway.

Abstract: A system and method of propagating exclusion records between a plurality of networked call centers is provided. Each call center includes a CTI system having a dynamic data record exclusion system. The system includes an exclusion record exporter and an exclusion record importer interfacing the dynamic data record exclusion system at each networked CTI system, which export and import exclusion records that are generated at one CTI system to the remaining networked CTI systems. The method begins by maintaining at least one exclusion table including at least one exclusion record in a first call center's dynamic data record exclusion system. Then, the exclusion records, along with a list of the networked call centers to which the exclusion records should be sent, are sent to an exclusion record exporter, where they are saved in a transfer file. The exclusion record exporter then transfers each transfer file to a defined directory at an exclusion record importer at at least one other networked call center.

A bandwidth allocation scheme allocates a set of CDMA channels for burst packet-switched channels, and data is time division multiplexed over the set of burst CDMA channels providing a wide bandwidth data pipe for packet-switched data.

Abstract: A communications system includes base transceiver stations providing wireless services for mobile units. The system further includes a packet network coupling the stations to a gateway. To distribute information received for communication to a mobile unit, the gateway may encapsulate the information as a multicast packet addressed to a multicast address. This multicast address corresponds to a multicast group associated with the mobile unit. The packet network distributes copies of the multicast packet to a group of stations that are registered for the multicast group. These stations may then communicate information from the multicast packet to the mobile unit using wireless communications techniques.

Abstract: A method and a device are provided for triggering an uplink transmission in a cable modem. A number of time indicators (301) are received in a downlink direction. There is established knowledge about a total time offset related to propagation delays in a network from which the time indicators are received. There is also established knowledge about an allocated uplink transmission slot number determined in relation to the received time indicators. The total time offset is reduced into a remainder value that is smaller than the total time offset. A shifted slot counter (304, 405) is synchronized to a shifted time base (302, 303) which has an offset to the time base provided by the received time indicators (301), said offset being equal to said remainder value. An uplink transmission triggering signal is generated as a response to said shifted slot counter (405) giving a certain slot number.

Abstract: With the addition of high-speed data traffic to traditional CDMA cellular networks, there is a need to efficiently utilize system capacity so that the quality of service of existing voice and low-speed data users is maintained while new high-speed data users are added to the network. Methods and systems are presented that control allocation of power to users, quality of service requirements, and/or user activity levels to enhance capacity utilization. These methods and systems are based on a method for estimating the capacity of a CDMA carrier with both voice and data users using an interference-based analysis of the reverse link. In particular, the methods enhance capacity utilization in a multi-code CDMA network architecture, in which several codes are allocated to a single high-speed data user for parallel transmission.

Abstract: An asymmetric network system manages bandwidth allocation and configuration of remote devices in a broadband network. A modular architecture of the system permits independent scalability of upstream and downstream capacity separately for each of the upstream and downstream physical paths. Allocation of downstream bandwidth to requesting devices is made according to bandwidth utilization by other devices, bandwidth demand by the requesting remote device, class or grade of service by the requesting remote device or bandwidth guaranteed to other remote devices. Configuration parameters remotely managed by the network include device addresses (global and local), transmission credit values, upstream channel assignment and upstream transmit power level. Further, management of device configuration profiles and bandwidth allocation occurs through control and response packets respectively generated by the network and the remote devices according to network operating software located at both ends.
