  • Patent number: 8688084
    Abstract: A method on a wireless user equipment (UE) device facilitates integration of an outgoing cellular call as an enterprise call. The UE device attaches to a wide area cellular network on which the device has a non-enterprise address. Upon blocking incoming calls, the UE device sends a request to a node in a data network to initiate an outgoing cellular call with an expectation of receiving an incoming circuit-switched (CS) call back from the network node within a time window. The incoming CS call contains an enterprise address associated with a user of the wireless UE device as a calling line identity to identify that the incoming CS call is related to the request to initiate the outgoing cellular call. The UE device indicates to the network node that a call leg is established between the enterprise user and the network node.

  • Patent number: 8606319
    Abstract: To consolidate session initiation protocol (SIP) messages a user equipment (UE) is made aware of all Internet Protocol (IP) multimedia subsystem (IMS) applications installed in its memory and on a universal integrated circuit card (UICC) and supported communication services. By obtaining this information before the initial IMS Registration, the UE can save resources by registering all local applications and communication services in single IMS registration.

  • Publication number: 20130263027
    Abstract: A non-transitory processor-readable medium storing code representing instructions to be executed by a processor to receive a set of data elements associated with a user-defined content having a content type. The processor interpolates the set of data elements to produce a first set of content data based on a filter domain associated with the user-defined content. The processor further refines the first set of content data based, at least in part, on the content type to produce a second set of content data. The processor also sends a signal representing the second set of content data such that the user-defined content is displayed based on the second set of content data.

  • Patent number: 8521170
    Abstract: In one embodiment, a scheme is disclosed for routing an incoming call in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network, wherein the incoming call is being directed to a user equipment (UE) device disposed in the network environment. A network node disposed in the IMS network is operable to perform a number of determinations with respect to the UE device's domain, state, applicability of user and/or operator policies and preferences, location, et cetera. The incoming call is terminated to an appropriate domain (e.g., CS domain or IMS domain) based at least in part upon the foregoing determinations.

  • Patent number: 8430547
    Abstract: A reaction-testing system is provided to simulate motion to an individual. Generally, the reaction-testing system includes a motion-simulating device, a reflective device, a control unit, and an input device that is activated by an individual In exemplary embodiments, the motion-simulating device includes a beam that accommodates a first and second plurality of light sources capable of, at least, alternating between an active and idle condition. These light sources are arranged amongst occlusion features in a mounting pattern such that light emitted from the first plurality is directly viewable by an individual and light emitted from the second plurality is indirectly viewed by the individual through the reflecting surface. The control unit is configured to sequentially activate the light sources sequentially to generate pulses of light on that, when perceived by the individual, appear as a light moving along a vector.

  • Patent number: 8428584
    Abstract: A system and method for accelerating network selection by a wireless user equipment (UE) device without having to perform a full band scan (FBS). In one exemplary embodiment, the wireless UE device is operable to scan in a network environment for discovering at least one network. Depending upon geographic region information decoded from the discovered network's identity information, a logic structure in the wireless UE device is operable to determine a subset of appropriate frequency data for selective scanning by said wireless UE device. Using the subset of appropriate frequency data, a selective scanning is performed for locating a network by the wireless UE device.
