Abstract: A method is provided for selecting a device in a telecommunications network in accordance with characteristics relating to the implementation of a telecommunications service, comprising the following steps: a) receiving a set of characteristics relating to said service; b) forming a first symbolic address for querying an address server, using at least one portion of the overall characteristics of the set on the one hand, and an address domain name on the other hand; c) sending the first address to the address server; d) receiving a list of one or more devices compatible with the characteristics; and e) selecting one device from the list.
Abstract: A method and apparatus for minimizing redundant enhanced uplink (EU) allocation requests and fault-isolating EU transmission failures that occur between a wireless transmit/receive unit (WTRU) and a Node-B. The WTRU transmits an enhanced dedicated channel (E-DCH) allocation request to the Node-B over an uplink (UL) EU channel. In one embodiment, if E-DCH allocation cannot be provided within a predetermined time period, the Node-B sends an acknowledgement message to the WTRU via a downlink (DL) EU signaling channel without sending E-DCH allocation information. The request is queued in the Node-B and the WTRU refrains from transmitting the same request until after the time period expires or resources become available. In another embodiment, appropriate actions are taken to correct EU transmission failures by determining whether an E-DCH allocation request was unsuccessfully delivered via the UL EU channel or whether channel allocation information was unsuccessfully delivered via the DL EU signaling channel.

Abstract: A system and method for facilitating communications between a mobile device and a network application are provided. A mobile device transmits a request for data change information that includes a time out interval. The network application receives the request and measures a time elapsed since the receipt of the data change request. The network application will only transmit a notification to the mobile device client if new data is received or the time out interval has elapsed. As notifications are received, the mobile client device tunes the time out interval based upon network and device parameters.

Abstract: A method of authenticating a user seeking access to an unlicensed wireless communication system includes delivering to an unlicensed wireless communication subscriber device licensed wireless communication system security information. An authentication result produced by the subscriber device is processed in response to the licensed wireless communication system security information. The authentication result is compared with an authentication value to selectively produce an authentication command. Unlicensed wireless communication between the subscriber device and an unlicensed wireless communication system base station is enabled in response to the authentication command.
Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.
Abstract: Guiding pieces on a bracket cover is engaged with attachment claws on a bracket body. This engagement serves to hold the bracket cover on the bracket body when the bracket cover is set at a first position. When the bracket cover is set at a second position, the engagement between an engagement piece and a hook piece serves to cooperate with the engagement between the guiding pieces and the attachment claws so as to hold the bracket cover on the bracket body. The bracket cover is firmly held on the bracket body when the bracket cover is set at the second position. The bracket cover is thus reliably prevented from detachment from the bracket body.
Abstract: A method and apparatus for transitioning between radio link protocols in a packet-based real-time media communication system. A wireless communication device such as a cell phone will operate under one radio link protocol (such as IS-856, also known as 1xEV-DO) to engage in packet-based signaling for setup of a packet-based real-time media session such as a push-to-talk session. Once the session is set up, the wireless communication device will then automatically transition to operate under a different radio link protocol (such as IS-2000, also known as 1xRTT), and will engage in packet-based real-time media communication in the session over that different radio link protocol. Preferably, the radio link protocol used for session setup signaling will provide for reduced setup latency, while the radio link protocol used for bearer communication in the session will provide for reduced jitter and improved real-time media communication.
Abstract: The present invention relates to a method of setting a traffic stream of a wireless communication considering terminal state information. The present invention provides a wireless communication system, comprising a base station for controlling a wireless communication and a terminal device connected to the base station to transmit and receive data, wherein the terminal device transmits terminal state information representing a state thereof to the base station and the base station sets data transmission mode using the received terminal state information. According to the present invention, there is an advantage in that a traffic stream can be maintained considering a state of the terminal, and thus, power consumption of the terminal can be minimized.
Abstract: When a station is within range of at least one AP that advertises load information and at least one AP that does not advertise load information, the station selects the best AP in terms of probable data rate. The probable data rate is determined based on signal strength and mode by indexing into a predefined table or by utilizing an algorithm. The selection may be skewed in favor of APs which advertise load information.

Abstract: Various schemes for performing inter-system handoff, e.g., from a UTRAN to a cdma2000 radio access network (RAN) are described. For a MAHHO scheme, the UTRAN uses measurements obtained by a multi-RAT device to determine suitable cdma2000 cell(s) for handover. The measurements are obtained by a candidate frequency search procedure, and the handover is accomplished by a handoff execution procedure. For a MDHHO scheme, the UTRAN relies on location information for the multi-RAT device to select suitable cdma2000 cell(s) for handover. For a CRHHO scheme, a new call is established on the cdma2000 RAN and the pending call on the UTRAN is released in a manner such that the handover appears seamless to the multi-RAT device. The multi-RAT device includes two modem processors that perform processing for the UTRAN and cdma2000 RAN and an application processor that controls the modem processors.

Additionally, third signals may be received via the first antenna at a third RFIC integrated within the mobile terminal, where the third signals comprise signals within a VHF/UHF broadcast band.
Abstract: A mobile terminal for use in a Global System for Mobile communication (GSM) system. A mobile equipment (ME) for use in the GSM system includes a Subscriber Identity Module (SIM) card and a Mobile Terminal (MT). The SIM card stores International Mobile Subscriber Identity (IMSI) information used for subscriber authentication and private information. The MT stores the IMSI and private information of a user, and contains a controller, which reads IMSI information from the SIM card when the SIM card is inserted into the MT, and denies access to the stored private information when the read IMSI information of the inserted SIM card is different from the stored IMSI information.
Abstract: A method, system, and device are provided for transmit channel request messaging in wireless half-duplex voice communication systems. A new transmit channel request message (TCRM) is provided and sent over a logical control channel from a receiving device capable of walkie-talkie-like functionality, during an active half-duplex session, to a transmitting device capable of walkie-talkie-like functionality, indicating that the transmit channel is requested. In some embodiments, the invention provides for the display of information on the transmitting device user interface (UI) indicating, during an active session, that another user wishes to talk. The TCRM includes an indication that another device has requested the transmit channel and preferably includes an identification of the device which sent the transmit channel request message. In some embodiments, a qualifier flag in the TCRM is used to specify what, if any, extended functionality in respect of the TCRM is to be performed.
