  • Systems and methods for mobile stations to identify radio access technologies
    Patent number: 10506473
    Abstract: A mobile station capable of being served via a first radio access technology (RAT) and a second RAT. The mobile station includes a component configured to receive a permission to identify a cell of the first RAT in absence of a first radio access type neighbour cell list for a serving cell of the second RAT. The mobile station also includes a component configured to identify a cell of the first RAT after receiving the permission.

  • Emergency services in home cells system and method
    Patent number: 8811935
    Abstract: A user equipment (UE) comprising a processor configured to cause the UE to transmit an emergency calls required indicator (ECRI) to a network component responsive to the UE receiving an instruction to place an emergency call; and to receive an emergency calls supported indicator (ECSI) prior to placing an emergency call, wherein a value of the ECSI indicates a type of emergency services supported by a femtocell, where the processor is further configured to cause the UE to transmit the ECRI before receiving the ECSI.

  • Indicating radio access technology information to mobile stations system and method
    Patent number: 8559387
    Abstract: An access node. The access node includes a component configured to communicate with a mobile station operating on one of a first radio access technology (RAT) and a second RAT. The component is configured to communicate a permission to the mobile station to attempt to identify a cell of the first RAT in the absence of communicating to the mobile station a first radio access type neighbour cell list for a serving cell of the second RAT.
