  • Patent number: 8611280
    Abstract: A system and method for network selection procedures for simultaneous network connectivity through multiple accesses comprises obtaining stored and registered PLMNs, determining whether PLMNs are both stored PLMN for access technology type Ai and registered PLMN, when no PLMNs are both, performing PLMN selection using a standard procedure, when only one PLMN is both, determining whether the PLMN satisfies a condition, and when the PLMN satisfies the condition, attempting to connect to the PLMN, and when more than one PLMN is both, creating a set of PLMNs, selecting one PLMN that satisfies the condition, from the set PLMN, attempting to connect to the selected PLMN, and when attempting to connect fails, removing the selected PLMN from the set, and selecting another PLMN. In one aspect, the PLMN that minimizes changes is selected. In one aspect, the PLMN that provides access to a larger number of access technologies is selected.

  • Patent number: 8514808
    Abstract: A media-independent handover (MIH) environment supports a MIH function that uses a mapping table to communicate with other MIH functions using a MIH transport protocol. The MIH function updates the mapping table upon receipt of a message having fields to invoke an operation. The operation can update an existing mapping or delete a mapping. The operation also can update a lifetime value for a mapping for a particular address. The mapping table includes mappings. A mapping includes a MIH function identifier, a list of transport addresses, and a lifetime value.

  • Publication number: 20130194573
    Abstract: In an optical sensor, a light emission system emits an irradiated light of a linear polarization in a first polarization direction toward a surface of a target object having a sheet shape from an incident direction which is inclined with respect to a normal direction of the surface. A first light detection system includes a first light detector arranged on a first light path of a specular reflected light, which is emitted from the light emission system and is specularly reflected from the target object. A second light detection system includes a second light detector arranged on a second light path of a diffuse reflected light which is diffusely reflected from an incident plane on the target object. The second light detector receives second light passed by an optical element which passes a linear polarization component of a second polarization direction perpendicular to the first polarization direction.
