Abstract: A wireless communication system having a Node B and a plurality of wireless transmit/receive units (WTRUs), includes a contention-based uplink (UL) channel and at least one downlink (DL) physical channel. The UL channel supports UL transmissions from the WTRUs to the Node B. The UL channel is randomly accessed by a WTRU when the WTRU is ready to transmit data. The DL physical channel supports DL transmissions from the Node B to the WTRUs. The DL transmissions include an acquisition indicator and information regarding said acquisition indicator. The acquisition indicator confirms whether the data transmitted over said UL channel was successfully received by the Node B.

Abstract: A method of providing information indicative of network coverage by one or more wireless service providers in a geographic area may include obtaining, at an information provider, performance indicators for a plurality of accesses to the information provider by a plurality of wireless devices. The performance indicators may be correlated with one or more network service areas. Related performance indicators may be aggregated to produce one or more aggregated performance indicators. A human-discernible representation of network performance for one or more network service areas may be produced.

Abstract: A low-power transmitting apparatus and transmission method in a wireless personal area network (WPAN). A length of a fragment, a data rate, and a transmission power is selected to transmit a frame with minimum energy consumption in a contention period and a contention-free period. Thus, a quality of service (QoS) requirement for the transmission can be satisfied and the data frame can be transmitted with less energy consumption. Even when the channel status changes, a new transmission criterion suitable for the changed channel status is selected to minimize the consumption of the unnecessary energy. Furthermore, the life span of the network according to the energy consumption under a restricted environment can be lengthened.

Abstract: Distributed routing provides a robust, scalable communication system free of bottlenecks associated with traditional wireless systems. The system includes subscriber units sending and receiving information packets using wireless communication links. The system also includes access points with each access point forming a coverage area for exchanging information packets with subscriber units within the coverage area. The system further includes distribution points receiving packets from access points. Distribution points form a distributed routing network. Each distribution point receives an information packet for distribution to a specified destination. If the destination is to a subscriber unit within the coverage area of the access point in communication with the distribution point, the information packet is forwarded to the access point. Otherwise, the information packet is forwarded to one of the additional distribution points.

Abstract: In a gateway, a packet received from a first network contains first address data conforming to the first network in the packet header and second address data conforming to a second network in an auxiliary header. The first address data of the packet is then rewritten with the second address data of the packet and transmitted from the gateway to the second network.

Abstract: Advanced communications features are provided in a mobile communications network having at least one mobile switching center and at least one mobile station subsystem. The mobile switching center and mobile station subsystem each communicate signaling messages according to a mobile signaling protocol. An indication is received that a half-duplex mobile communications session is to be initiated between a first mobile station subsystem and a second mobile station subsystem. The first and second mobile station subsystems include full-duplex communications apparatus for use in full-duplex mobile communications sessions. The half-duplex mobile communications session relies on the first and second mobile station subsystems, and all of the reliance is only on the full-duplex communications apparatus. Mobile communications telephone calls are established with the first mobile station subsystem and the second mobile station subsystem.

Abstract: Various embodiments are described herein to address the need to have a method and apparatus that improve the resource efficiency of inter-PDSN (142 to 141) dormant mode handoffs. Promptly after the completion of signaling (218) for PPP connection establishment and MIP registration (if supported), as required for an inter-PDSN dormant mode handoff, an access network (AN) 121 expedites the release of communication resources such as the wireless traffic channel, the SCCP connection, and the A8 bearer connection. Thus, in an inter-PDSN dormant mode handoff the packet data session of an MS (101) is promptly transitioned back to the dormant packet data state. This enables communication resources to be freed for other calls and/or handoffs in a more timely manner than is enabled today.

Abstract: One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multi-channel audio, video, control, timing, closed captioning or other digital data.

Abstract: A scheme for using a virtual UNI (user network interface) to allow standards-based signaling protocols (e.g., Q.2931) to be used to manage the addition and deletion of AAL2 channel identifiers (CIDS) associated with sub-multiplexed AAL2 common part sub-layer cells is described herein. An ATM node is configured to dynamically establish ATM adaptation layer 2 (AAL2) channel identifiers (CIDS) on a call-by-call basis using standards-based call control signaling protocols mapping CIDs to a virtual path/virtual channel (VP/VC) within an ATM standard call control protocol.

Abstract: In an apparatus for controlling reply signal transmission in a reply signal transmitter that generates and transmits a reply signal according to an error check in packet data received through a radio channel in a mobile communication system, an error detection part generates a reply signal corresponding to the error check from the packet data received through the radio channel. A spreading part spreads the reply signal to output the spread reply signal. A transmission power control part carries out a power control operation for the spread reply signal with a power value that differs according to a packet data transmission rate of a packet data channel. A transmission part transmits the reply signal outputted by the transmission power control part through a radio channel.

Abstract: A reverse transmission controlling method in a mobile communication system, after receiving forward information, commanding the increase or decrease of the reverse data rate received on a forward control channel from a base station, a mobile station determines whether the previous rate increase available information transmitted to the base station on a reverse control channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase. The mobile station increases the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmits reverse data at the increased reverse data rate.
