  • Patent number: 8380207
    Abstract: A system and methodology that resolves complex mobility handling issues in Long Term evolution (LTE) networks, overlaid with Universal Mobile Telecommunications System (UMTS) macro and UMTS femtocells that share a common UMTS Absolute Radio Frequency Number (UARFCN), is provided. Moreover, an LTE user equipment (UE) includes a femto identification component that differentiates between the UMTS macro and UMTS femtocells by employing Location Area Code (LAC) data. In an aspect, the femto identification component ensures that the LTE UE connects to the UMTS femtocell as soon as the LTE UE enters the UMTS femtocell coverage area, even when the LTE radio frequency (RF) signal is deemed sufficient for communication. Further, the femto identification component ensures that the LTE UE stays connected to the LTE network, as long as possible, while outside of the UMTS femtocell coverage area.

  • Publication number: 20120317448
    Abstract: Error information is sent from a terminal adaptor that accesses a wireless network to terminal equipment coupled to access the wireless network through the terminal adaptor. The error information is sent in response to existence of any one of a plurality of errors conditions with respect to access to the wireless network. The error information includes an error type identifying a domain associated with a source of the error condition being reported and an error code providing a reject error cause for the error condition. One of the error conditions may include an unsolicited error received by the terminal adaptor from the wireless network or when a request by the TA is ignored by the wireless network.

  • Publication number: 20120302239
    Abstract: The disclosed subject matter relates to an architecture that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.

  • Publication number: 20120280813
    Abstract: An apparatus includes a memory containing a subscriber entitlement profile for a subscriber to a wireless communications network. The apparatus includes a controller configured to provide an indication of whether the subscriber is entitled to a service based on the subscriber entitlement profile. The memory and controller may be included in an integrated circuit card. The service may be unassociated with a rate plan associated with the subscriber. The apparatus may include a service entitlement facility configured to access a service of the communications network based on a user request for the service and the indication. The service entitlement facility may be further configured to determine whether or not a subscriber is entitled to the service of the wireless communications network based on the subscriber entitlement profile stored in the memory and further configured to access the service if the subscriber is entitled to the service.

  • Publication number: 20120220307
    Abstract: Devices, systems, and methods are disclosed which aggregate presence detections, and use the diversity of presence detections to resolve presence ambiguities and increase the correctness of information. Presence confidence levels and reliability values increase the effectiveness of services based on presence. A variety of methods enable presence detection and reporting. Each of these methods has advantages and disadvantages. The limitations of each of the individual methods are overcome with exemplary embodiments of the subject disclosure.

  • Publication number: 20110077051
    Abstract: Devices and methods are disclosed by which a smart card or UICC that is removably insertable into a wireless terminal will only allow operation in either a specific terminal or a specific set of terminals. A mechanism to restrict the set of terminals that a UICC will operate with based upon logic embedded in a memory within the UICC. The UICC receives specific information from the wireless terminal when the terminal is turned on. If the information received satisfies a plurality of rules or conditions stored within the UICC, the UICC functions normally and the terminal may be registered with the network. If the UICC is inserted in an unsupported terminal, the UICC will refuse to function normally. This provides a deterrent against UICC theft.

  • Publication number: 20100153046
    Abstract: Devices and methods are disclosed which relate to an LCD device responding to an AT command which solely activates the backlight of the LCD device. An LCD device is programmed to respond to two distinct backlight AT commands. One command turns the backlight on, and another command turns the backlight off. These backlight AT commands are programmed into LCD device testing equipment so that accurate photographs are taken of the LCD device, and results are improved. The backlight AT commands are also used as part of the programming for user-end applications.

  • Patent number: 6606486
    Abstract: A text entry method simplifies entry of the text messages in a mobile phone having a limited number of entry keys. A word list is stored in the phone's memory. The word list is divided into a plurality of groups and each group is associated with a particular group key on the keypad. The user first selects a word group by pressing the corresponding group key. The user can then scroll through the words in the group to select the desired word. The selected word may optionally then be translated into a codeword and the codeword then transmitted to a remote location. Individual characters may also be selected and translated in a similar manner in some embodiments.

  • Patent number: 6445914
    Abstract: A method of activating a mobile station used in a cellular network system provides subsidy protection for a cellular operator. The method comprises the steps of installing a subscriber identity module (SIM) in the mobile station, the SIM having an IMSI file and storing the first indicia uniquely identifying the cellular operator, the mobile station storing second indicia uniquely identifying the cellular operator; comparing the first indicia to the second indicia to determine if the SIM and the mobile station are valid for the cellular operator; and if the SIM and the mobile station are valid, then storing a mobile identity number in the IMSI file of the SIM.

  • Patent number: 6370506
    Abstract: Communication devices, methods, and computer program products may be used to transmit information to a destination by associating a voice command with the destination and associating a signaling message with the voice command and with the destination. After establishing communication with the destination, speech input that is received from a user is compared with the voice command to determine if there is a match. If the speech input matches the voice command, then the signaling message associated with the voice command is transmitted to the destination. A user may therefore be relieved of the burden of having to remember the keystrokes to perform a specific operation or function by embedding the signal(s) corresponding to the operation in the signaling message. Moreover, because the signaling message is associated with both the voice command and the destination, the same voice command may be used to perform an operation on more than one destination.
