  • Publication number: 20150234221
    Abstract: A sub-wavelength thin-film metal grating is placed inside a liquid crystal variable optical retarder at a selected distance from a reflective electrode to form a reflective half wave plate, thereby reducing polarization dependence of the optical retardation generated by the variable optical retarder. The approach enables to form within the device the reflective half wave plate that is suitably thin without modifying the reflective electrode of the device.

  • Publication number: 20150045039
    Abstract: A call loop avoidance capability is provided for preventing formation of a call loop resulting from handling of a mobile terminated (MT) call in parallel with a location update for a mobile device (MD) in a wireless communication network. The call loop avoidance capability prevents formation of a call loop between an old mobility and call management entity (MCME) and a new MCME when delivery of an MT call to an MD is performed while the MD is in the process of moving from the old MCME to the new MCME using a location update procedure. An enhanced call routing procedure supports direct delivery of the MT call from the new MCME to the MD (rather than delivery of the MT call by the new MCME to the MD via the old MCME) in order to prevent formation of a call loop between the old MCME and the new MCME.

  • Patent number: 8948735
    Abstract: A method for delivering a mobile terminated call to a mobile device communicating with a mobile switching center (MSC) in one example comprises steps of attempting to deliver the mobile terminated call to a mobile device, receiving a message that the mobile device is no longer in the location area served by the visiting MSC and forwarding the mobile terminated call to a different visiting MSC. The mobile terminated call is forwarded directly from one VMSC to another VMSC without requiring two potentially international calls to be placed serially from the GMSC to a VMSC. This method of Mobile Termination Roaming Forwarding can reduce substantial delay in call setup while saving network resources during establishment of the first call.

  • Patent number: 8818333
    Abstract: As a mobile device moves from one location area to another, the mobile device detects the different location identifiers broadcast by the wireless network(s) in those locations areas. The mobile device stores the location identifier for the last location area in which the mobile device was located. By comparing a received location identifier to the stored location identifier, the mobile device determines if the mobile device has entered a new location area. If so, the mobile device sends a location update request. In one embodiment, if the location update request is for a location area to which access by the mobile device is restricted, the network sends a communication to the mobile device that triggers the mobile device to update a location identifier stored at the mobile device to the location identifier for the restricted location area so that the mobile can update the network after entering/selecting a different location area.

  • Patent number: 8774797
    Abstract: A Gateway Mobile Switching Center (GMSC) of a home Public Land Mobile Network (PLMN) is provided. In one embodiment, the GMSC is configured, for receiving a roaming caller originated call from a visited PLMN including a Routing Number (RN), validating the RN against configured Network Camel Subscription Information (N-CSI) in response to receiving the roaming caller originated call, and sending a home network issued Initial Detection Point (IDP) to a Service Control Point (SCP) of the home PLMN in response to the RN being successfully validated. The home network issued IDP includes said RN. The GMSC is further configured for receiving at least a portion of information for facilitating connection of the roaming caller originated call from the SCP of the home PLMN and facilitating connection of the roaming caller originated call in response to receiving the at least portion of the information.

  • Publication number: 20140102203
    Abstract: A standing wave amplification device for vibration signal collection includes a sensing rod (11) acting as standing wave transmission medium. A standing wave formation device includes two fixing support devices (12) distributed along the axial direction and connecting the sensing rod (11) to an operating arm (14). The two fixing support devices (12) respectively collect vibration waves and transmit them to the sensing rod (11) from two different locations of the operating arm (14). The vibration waves are superimposed to form a standing wave on the sensing rod (11). A vibration sensor (13) is connected to the sensing rod (11) and the vibration sensor (13) is between the two fixing support devices (12). A wave detected by the vibration sensor (13) is the standing wave. Compared with transverse wave or longitudinal wave transmitted in the transmission medium of prior art, the standing wave has advantages of larger amplitude and more obvious vibration effect.

  • Patent number: 8588772
    Abstract: A method and apparatus for delivering a mobile terminated call to user equipment (UE) in a circuit switched fallback (CSFB) capable wireless network system using prepaging. When the VMSC registered in the HLR of the called UE receives a provide roaming number message from the HLR indicating that a CS call to the UE has been originated at a GMSC, the VMSC starts a paging process with a mobility management entity (MME) then returns a mobile station roaming number (MSRN) to the HLR when the called UE is in EMM-connected mode. Alternatively, the VMSC sets a guard timer and returns the MSRN to the HLR when the guard timer expires. In the meantime, the VMSC remain in a paging stage waiting for the response from the UE falling back to the UMTS/GSM network from the LTE network.

  • Patent number: 8452278
    Abstract: A method for facilitating inter-PLMN (Public Land Mobile Network) roaming comprises a plurality of operations. A home PLMN of a caller's wireless communication device performs an operation for determining that the caller's wireless communication device is not located in the home PLMN and, in response to determining that the caller's wireless communication device is not located in the home PLMN, an operation for facilitating a call routing service in a Service Control Point (SCP) of the home PLMN. The call routing service causes a call originated by the caller's wireless communication device while roaming in a visited PLMN to be routed back to a Gateway Mobile Switching Center (GMSC) of the home PLMN thereby allowing the home PLMN to have control over the roaming caller originated call and to have limited dependency on the visited PLMN.

  • Patent number: 8351962
    Abstract: Paging of a mobile device within a mobile pool area serviced by two or more mobile switching nodes is reduced using logical paging areas. The mobile pool area includes a plurality of location areas, each serviced by the two or more switching nodes. In addition, the mobile pool area is divided into multiple logical paging areas, in which each logical paging area includes at least two location areas. Upon receiving a mobile terminated call for the mobile device, if the location area of the mobile device is unknown, the logical paging area within which the mobile device is located is determined in order to page the mobile device and deliver the mobile terminated call to the mobile device.
