  • Patent number: 7848271
    Abstract: The invention relates to a system and a method for selectively reducing power consumption of a communication device communicating with a network. In the method, it comprises the following steps: de-activating at least one communication subsystem of the device during intervals when the device is placed in a power save mode; and while the device is in the power save mode the method re-activates the subsystem in two instances. For the first instance, the communication subsystem is re-activated in relation to a first connection condition, and is then de-activated after a first event. For the second instance, the subsystem is re-activated in relation to a second connection condition and is then de-activated after a second event.

  • Patent number: 7848288
    Abstract: A method and apparatus for estimating channelization codes in a wireless transmit/receive unit (WTRU) using blind code detection (BCD). A WTRU receives communication bursts and detects a midamble in the received burst. A candidate code list is generated in accordance with the detected midamble. The candidate code list includes channelization codes intended for both the intended WTRU and other WTRUs. Active channelization codes among the codes in the candidate list are identified, and the identified codes are forwarded to a multi-user detector (MUD). Since the orthogonal variable spreading factor code maintains the orthogonality between codes of different SF, SFs of other WTRUs follow the SF of the intended WTRU. Moreover, since the data for other WTRUs is not used in symbol processing after MUD, the performance of MUD for the intended WTRU is preserved with the SF ambiguity of other WTRUs.

  • Patent number: 7848762
    Abstract: A method of using a non-GPS-derived technique to estimate the location of an Assisted-GPS-enabled wireless terminal for the purposes of generating location-specific assistance data for the wireless terminal is disclosed. The wireless terminal then uses the assistance data to acquire and process one or more GPS signals and to derive information that is probative of the wireless terminal's location. The GPS-derived location information is then combined with non-GPS-derived location to form an estimate of the location of the wireless terminal that is better than can be derived from either alone. This combination of GPS-derived and non-GPS techniques is particularly useful when the wireless terminal can only acquire one or two GPS signals because it is not possible to determine the location of the wireless terminal with only two GPS signals alone.

  • Patent number: 7843894
    Abstract: After a user device unsuccessfully attempts to establish upstream communication with a central network equipment downstream frequency to which it has tuned, an identifier corresponding to the tuned-to downstream frequency is removed from a cache of the user device. The frequency identifier stored in the cache typically corresponds to a frequency to which the user device has previously successfully tuned. The frequency identifier is removed from the cache after a predetermined attempt period, which may be determined by the number of attempts to establish communication that are made after previous unsuccessful attempts.

  • Patent number: 7844237
    Abstract: Systems and methods of position sensing for a receiver, via employing an ability thereof to receive signals in a broader range than what such receiver is initially tuned for. A frequency skip component can skip channel frequencies such that the spectrum range is scanned without a typical requirement of tuning to all the channels during such scan. Accordingly, the subject innovation enables the entire spectrum of interest to be scanned at a substantially reduced amount of time. Location interpolation for the receiver and time stamping of received signals can be implemented as part of the position sensing.

In one such embodiment, the building-security method is implemented for bidirectional, wireless communication between a control panel device and peripheral devices. Each of the devices includes a wireless communication circuit to effect wireless communications. The control panel wirelessly sends synchronization information to at least one of the peripheral devices. Power consumption is reduced for at least one of the wireless communication circuits by coordinating a communications time interval and a selected channel for communication between the control panel device and the peripheral device to effect wireless communications between the control panel and the peripheral device. The selected channel is one channel from a sequence of channels used for wireless communications between the control panel device and the peripheral devices.

  • Patent number: 7826406
    Abstract: A mobile communication device uses a condensed text message store wherein individual messages of a thread are stored in such a manner that the thread can later be reconstructed for display. By storing individual messages rather than thread objects including duplicative content, device memory is conserved. Network bandwidth can also be preserved by sending only individual messages between the device and a central server (which server may also utilize a condensed message store).

  • Patent number: 7818000
    Abstract: Systems and methods are disclosed for selecting a preferred foreign wireless network from a plurality foreign wireless networks. One embodiment of the invention comprises a home wireless network that includes an HLR and a managed roaming system coupled between the HLR and a plurality of foreign wireless networks. The managed roaming system receives registration messages for roaming subscribers being transmitted from the foreign wireless networks to the HLR. The managed roaming system monitors the number of registration messages received from the foreign wireless networks and forwards the registration messages to the HLR. The managed roaming system selects a preferred foreign wireless network based on the number of registration messages received from the foreign wireless networks over a time period. The managed roaming system then forwards subsequent registration messages from the preferred foreign wireless network to the HLR, and blocks registration messages from non-preferred foreign wireless networks.

  • Patent number: 7809350
    Abstract: In one example, a first message center address associated with a home message center and a second message center address associated with an emergency message center are stored in memory of the mobile device. A user input request for communicating a short message is received through a user interface of the mobile device. If the user input request is identified as being for an emergency message, the second message center address is read from the memory and provided in a message center address field of the short message. The short message having the second message center address in the message center address field is then transmitted by the mobile device to the wireless network. The network identifies the second message center address in the message center address field and, in response, causes the short message to be sent to the emergency message center which is local to the network.
