  • Patent number: 9924351
    Abstract: A user equipment (UE) is provided. The UE comprises at least one component that is configured to detect an event of one of the UE changing routing area and the UE changing radio access technology from a long-term evolution (LTE) network to a global system for mobile communications enhanced data rates for GSM evolution radio access network (GERAN) or to a universal mobile telecommunication system terrestrial radio access network (UTRAN) and, responsive to detecting the event, to deactivate one of a packet data protocol (PDP) context and an evolved packet system (EPS) bearer.

  • Publication number: 20170195924
    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.

  • Patent number: 9554300
    Abstract: If a wireless device does not know how many data contexts can be supported, then the wireless device might attempt to establish more data contexts than are supported. Such attempt would normally be rejected. However, the signalling involved in the attempt to establish another data context and the rejection of that attempt is considered wasteful. Embodiments of the present disclosure allow such waste to be reduced or avoided by signalling to the wireless device when the maximum number of data contexts is reached or when it is about to be reached. Such signalling can occur before any attempt to establish more data contexts than are supported. Thus, wasteful signaling involved with attempting to establish more data contexts can be avoided.
