Abstract: Disclosed is a method for storing an identifier in a first station having a secure non-volatile data store protected by cryptographic data, an identifier flag for indicating that the identifier has been written to the secure data store, and an authenticated trust agent that prohibits writing of an identifier to the secure data store if the identifier flag is set. In the method, the identifier is written to the secure non-volatile data store, wherein the identifier written to the secure data store is encrypted using the cryptographic data. The identifier flag is irreversibly set after writing the identifier to the secure data store so that the trust agent prohibits another write of an identifier to the secure data store.

Abstract: The access terminal is configured to wirelessly send to a data system a request that the data system assign an access terminal identifier (ATI) to the access terminal. The access terminal delays transmission of the request until after a user of the access terminal has employed the access terminal to request a packet data service from the data system. In some instances, the data system is an Evolution, Data Only (EV-DO) system and the access terminal identifier (ATI) is a Unicast Access Terminal Identifier (UATI) generated by the Evolution, Data Only (EV-DO) system.

Abstract: A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to “everything else” or “the air”. The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.

Abstract: CDMA code channels are acquired using a crystal oscillator that is not temperature compensated and that generates a tuning signal with relatively large frequency error (e.g., +/?5 ppm). Channel acquisition is first attempted at no offset from a start frequency that is obtained by fitting an ideal temperature/frequency error curve to available actual data points. Following unsuccessful pilot acquisition, the offset frequency is stepped in a “spiral” manner, and pilot acquisition is retried. When the pilot and synchronization channels are successfully acquired, but the system identification is unexpected, an adjacent channel image has been acquired, and the offset frequency is bumped by a large step (e.g., 15 kHz). Pilot acquisition is retried using spiral stepping. The crystal oscillator is calibrated after each successful acquisition of the pilot, synchronization and paging channels by retaining a data point in a frequency adjustment table for the temperature at which frequency acquisition was successful.

Abstract: Methods and apparatuses are provided that facilitate avoiding one or more wireless communication systems based at least in part on determining a level of unreliability of a reverse link channel related to a system. This can be based at least in part on determining whether the system can be accessed over the reverse link channel. If not, the wireless communication system can be avoided to conserve power utilized to perform such access attempts. Where the unreliability is temporary, however, some access attempts can be performed for systems of higher priority than a current system during the period of avoidance of one or more higher priority systems.

Abstract: A method and system are provided for remotely collecting activation information for one or more components, modules, and/or elements of a wireless device. The wireless device may detect its activation with a service provider to be able to operate or communicate over a network. Once activated for service, the wireless device may be adapted to collect information about which of its components, modules, and/or elements have been activated. Such activation information may be reported to a remote activation server that tracks such collection from a plurality of wireless devices. The collection of information pertaining to activation of specific components, modules, and/or elements of a wireless device may be used to pay royalties to the manufacturer or vendor of the components, modules, and/or elements. The collection of activation information may also be used to determine which features are being activated in the wireless device.

Abstract: Embodiments disclosed herein relate to methods and systems for reporting and compiling connection failures in wireless communication systems. In an embodiment, when an access terminal experiences a connection failure (e.g., an unintended one), the access terminal may generate a connection failure record associated with the event, and send a message containing the connection failure record to an access network it has since established the connection. The access network may send a message containing a connection failure report acknowledgement (ACK) message to the access terminal, upon reception of the connection failure report message. The network operators may use the connection failure records thus compiled to identify problematic spots in the system and improve the quality of service.

Abstract: A power management technique for a Subscriber Identity Module (SIM), makes use of a voting process to determine when to power-up and power-down the SIM. In particular, the voting process determines whether software modules running on a wireless communication device (WCD) require current or imminent access to the SIM. The voting process is designed to make more efficient use of the SIM without sacrificing performance. A modified security authorization process can be added, in which the WCD caches a user access code in memory for authenticating the user to the SIM to gain access to the secure features of the SIM. The security verification process avoids the need for the user to enter the access code each time the SIM is powered up in the course of the power management routine, reducing user inconvenience and maintaining performance.

Abstract: Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption. Acquisition attempts may be performed in a “ping-pong” manner to improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.

Abstract: One aspect of the invention provides a system, apparatus and method that allow a wireless communication device to intelligently search for and select a communication cell based on a system identifier (SID) and network identifier (NID) order of preference rather than just pilot signal strength. Generally, a mobile device scans a frequency channel associated with the highest preferred SID/NID for pilot signals at different PN offsets. The cell associated with the strongest pilot signal detected is queried to determine whether it belongs to the SID/NID sought. If the selected PN offset belongs to a cell associated with the SID/NID sought then it is used for communications. Otherwise, the SID/NID identification process is repeated for the next strongest PN offset detected on the same frequency channel. If no pilot signals meeting these criteria are found in the frequency channel, the next highest preferred SID/NID is selected and the process is repeated.

Abstract: This disclosure is directed to techniques for condensed voice buffering, transmission and playback. The techniques may involve identification of encoded voice frames as either speech or a pause, and selective exclusion of a portion of the frames for storage, transmission or playback based on the identification. In this manner, the techniques are capable of condensing a series of encoded voice frames. When variable rate coding is employed, a pause frame may be identified, for example, based on a threshold comparison for the rate of the encoded frame. In some cases, the techniques may involve excluding only a portion of the identified frames from a consecutive sequence of the identified frames, thereby preserving a minimum number of the identified frames needed for intelligible conversation.

Abstract: An in-bound call directed telephone station, and a method, which may be embodied in a computer readable medium, directs a telephone station based on an in-bound call. The inbound directed telephone station includes means for providing a handset having a call receiver and a call originator, means for providing a first memory location, coupled to the call receiver, and means for providing a comparator coupled to the first memory location and to the call receiver. Upon receipt of an inbound call by the call receiver and before the call receiver answers the in-bound call, the comparator compares an identifier of the in-bound call to an identifier list in the first memory location and terminates receipt of the in-bound call by the call receiver. Upon locating a match between the identifier list and the identifier of the in-bound call, the comparator automatically activates the call originator to perform a function associated with the in-bound call identifier.

Abstract: A system and method for determining 1xEV-DO availability for a packet data call in a wireless device is presented. When the wireless device receives a request to initiate a packet data call, the device determines if it currently has access to a preferred 1xEV-DO channel. The determination can be made by consulting a 1xEV-DO availability list stored in persistent memory on the wireless device. If available, the wireless device originates the packet data call on the 1xEV-DO channel. If the device is using a CDMA system that has 1xEV-DO channels but the availability or usability of those channels are unknown, the device polls the signal strength on the 1xEV-DO channels to determine the best 1xEV-DO channel to use for the packet data call. If no 1xEV-DO channel is available or if none of the available 1xEV-DO channels are usable, then the device originates the packet data call on a CDMA channel.
