  • Publication number: 20120190351
    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: 8133800
    Abstract: A method of fabricating a thickness of silicon material includes providing a silicon ingot material having a surface region and introducing a plurality of particles having an energy of about 1-5 MeV through the surface region to a depth to define a cleave region and a thickness of detachable material between the cleave region and the surface region. Additionally, the method includes processing the silicon ingot material to free the thickness of detachable material at a vicinity of the cleave region and causing formation of a free-standing thickness of material characterized by a carrier lifetime about 10 microseconds and a thickness ranging from about 20 microns to about 150 microns with a thickness variation of less than about five percent. Furthermore, the method includes treating the free-standing thickness of material using a thermal treatment process to recover the carrier lifetime to about 200 microseconds and greater.

  • Publication number: 20090305666
    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.

  • Publication number: 20090152162
    Abstract: A carrier apparatus for holding a shaped sheet material includes a first frame structure with a first front surface including a first outer peripheral region and a first inner peripheral region separated by a first step. The apparatus further includes a second frame structure with a second front surface including a second outer peripheral region and a second inner peripheral region separated by a second step. The second front surface is configured to engage with the first front surface so that the second outer peripheral region is at least partially in contact with the first outer peripheral region and the second step circumferentially mates the first step with the second inner peripheral region opposing to the first inner peripheral region by a gap. The carrier apparatus further includes one or more locking mechanisms and a shaped wing structure extended from outer peripheral edge of the first frame structure.

  • Publication number: 20080261629
    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.
