  • Publication number: 20030153320
    Abstract: Two types of contention channels are used to accommodate broadband packet data in a satellite communication network. A first contention channel is used by unsynchronized user terminals to access the system and request a traffic channel. The first contention channel is of a sufficient duration to accommodate a RACH message, as well as the timing uncertainty between user terminals within a given spot beam. A second contention channel is shorter in duration than the first contention channel, and is narrowband, so that more than one second contention channel may be transmitted within the bandwidth of the broadband traffic channels. The second contention channels are used by synchronized user terminals for transmitting packet RACH, or PRACH, messages. The more efficient nature of the PRACH channels accommodates the increased overhead associated with bursty packet data, without the capacity cost of the longer duration RACH channel.

    Abstract: A portable communication equipment comprises a radio communication sections (13), (14) for transmitting and receiving a CDMA signal, a base band modem section (16) for modulating a speech signal into a CDMA signal and demodulating a CDMA signal into a speech signal, and a CPU (17) for controlling the transmission and reception of a CDMA signal. When the equipment fails in capturing a selected channel and falls in a condition when a system was lost, the CPU (17) retries to capture the selected channel. The CPU (17), when it fails in capturing the selected channel, selects another channel only when it tries to capture the selected channel for a predetermined number of times as well as it does not obtain an overhead message. With this arrangement, it is possible to capture an appropriate channel if an unsuitable channel is selected and the portable communication equipment falls into a condition when a system was lost.

  • Publication number: 20030153328
    Abstract: When a piece of network equipment is determined to be stolen or missing, a hardware tracing tool mounted within the network detects the distinctive hardware fingerprints of the missing hardware within Internet traffic and extracts the device's IP address to trace the location of the missing equipment. As Internet messages or data packets cross through servers containing the tracing tool, the data packets are decompiled to retrieve unique identifier indicia (hardware fingerprints), such as a computer's MAC address, for example. The extracted fingerprints are then compared with fingerprints stored in a database of missing hardware using a hashing or mapping function, and the server system is alerted to a match. The IP address of the device transmitting the matching indicia is then extracted to determine the location of the missing or stolen network hardware.

  • Publication number: 20030153332
    Abstract: A system and method in a mobile communication network for providing enhanced user privacy when responding to a location request from a client requesting location information for a mobile terminal. The system includes a mobile location node, a service node serving the mobile terminal, and a home location register/home subscriber server (HLR/HSS) associated with the mobile terminal. A list of approved codewords and a list of approved service types are stored in the HLR/HSS, and only location requests that include approved codewords or service types from these lists are accepted by the system. The mobile location node may also store a list of approved service identities, and may reject location requests that do not include a service identity matching one of the approved service identities. A mapping function in the mobile location node maps service identities to service types and sends them to the HLR/HSS or to the service node for comparison with approved service types.

  • Publication number: 20030153334
    Abstract: A network station sends a switching instruction to a mobile unit. The mobile unit has two receiving sections and a transmitting section operable in two data formats. Upon receipt of the switching instruction, the first receiving section switches from a first data format to a second data format. The transmitting section sends an acknowledgment signal to the network. The first receiving section and transmitting section then attempt to switch to the second data format. The second receiving section remains in the first data format. The first receiving section then attempts to achieve synchronization. If synchronization is successful, a completion notice is sent back to the network station and the second receiving section is switched from the first data format to the second data format.

  • Publication number: 20030153335
    Abstract: A radio telecommunication system, and in particular an in-building system, comprises a number of basestations connected together by a local area network (LAN) at least one of the basestations (BS) is capable of receiving a control channel transmitted by one or more of the other basestations (BS) of the telecommunication systems, from which it derives frequency reference and time base synchronisation data to enable the basestation to correct the frequency and time offset of its own transmissions with respect to the other basestations (BS) in the system. Also connected to the LAN is a controller (PC). The controller receives transmission measurement signals from each of the basestations (BS) and processes these transmission measurement signals to select radio frequency channels on which the basestations of the system should transmit to minimise interference with an external telecommunications system.

  • Publication number: 20030153337
    Abstract: An image memory stores, for example, an image taken by a camera and an image obtained via a route of an antenna, transmit/receive switching section, receiving section and demodulating section. At a time of an incoming call, a controller reads out an output of the demodulating section to obtain a telephone number, etc., of a calling party's side and reads out an image corresponding to the obtained telephone number, etc., to allow it to be displayed on a display section. This arrangement achieves a mobile radio terminal which, even if it has a relatively small display section, enables the user to readily identify the calling party at a time of an incoming call.

  • Publication number: 20030153338
    Abstract: Autoband's distributed networking intelligence provides a novel architecture capable of dynamically reconfiguring communications pathways consisting of links whose transmission media are opportunistically and dynamically selectable. At least one constituent node in such automatically configurable transient pathways is mobile, for example, information (source) server, intervening router node(s), gateway server and/or client device. Additionally, Autoband's ad hoc communications pathways may seamlessly and dynamically integrate (i.e., “graft”) into standard fixed node networks such as terrestrial networks, other wireless networks or combinations thereof. These communications may consist of point-to-point or multicast links. An economic market-based approach further assures allocation of available network resources (i.e., bandwidth and processing) needed to achieve the most optimally resource efficient communications pathway configurations for the totality of communications.
