  • Patent number: 7885666
    Abstract: Disclosed is a method and apparatus for determining the new sample points of the location determination system in a wireless environment. In the training phase, after knowing the distribution of the observed radio signal of a location for a target device, the uncertainty of the probability distribution of the received radio signal is analyzed by a location probability distribution model. The radio signal distribution differences are calculated, and the penalties between the location in question and its nearby locations are also calculated, thereby determining whether a location is the candidate of new sample points or the recalibration points. This invention has nothing to do with decision rules and will not undergo the problems of choosing inappropriate decision rules. It also provides a penalty model for generating penalty of error prediction from one location to another location, which can as well easily mitigate the problem on the sample points with the double-role attribute of the border line.

  • Patent number: 7885668
    Abstract: Reliably identifying an AP through which a user device is accessing one or more networks, and reliably determining the current network location of the user device. An AP and network location may be reliably identified using a set of transmitter fingerprints unique to the AP or network location, respectively. In response to a user device receiving at least one signal from at least one unknown entity, a transmitter fingerprint set of the at least one entity may be determined from the at least one signal. It then may be determined whether the at least one entity is an AP having an ID known to the user device, and/or whether the current network location is known by the user device. The user device may determine information that may be divulged with the at least one entity based on this determination.

  • Patent number: 7885670
    Abstract: The invention discloses a communication method of a dual-mode terminal, including: a Mobile Switch Centre (MSC) sends a message containing calling party information to an access functional entity of a High Rate Packet Data (HRPD) network via an InterWorking Solution (IWS) after receiving an initiated paging to a dual-mode terminal in the HRPD network; the access functional entity of the HRPD network sends a message containing the calling party information to the dual-mode terminal; the dual-mode terminal performs a subsequent communication according to the received calling party information. In the invention, upon receiving initiated paging from a dual-mode terminal in an HRPD network, the MSC sends a message containing the calling party information to an access functional entity of the HRPD network via the IWS, complexity of message processing is decreased, time of message processing is reduced.

  • Patent number: 7885671
    Abstract: A system and method for state synchronization between a base station and a mobile station in a mobile communication system. A count value indicative of a state change of the base station is received. The received current count value is compared with a previous count value previously received and stored. If the current count value is different from the previous count value, the mobile station performs a network entry procedure with the base station.

  • Patent number: 7885679
    Abstract: The mobile communication terminal includes a first unit which measures a SIR of a signal received from a base station, a second unit which determines a target SIR, and a third unit which compares the SIR measured by the first unit to the target SIR, and produces TPC data in accordance with the result of the comparison, the TPC data being used for controlling signal-transmission power by which the base station transmits a signal to the mobile communication terminal, the TPC data being transmitted to the base station together with a signal to be transmitted to the base station from the mobile communication terminal. The second unit lowers the target SIR if a signal for calling is not received from the base station by a predetermined period of time, and further if communication quality between the mobile communication terminal and the base station is equal to or greater than threshold quality.
