  • Patent number: 8254879
    Abstract: A communication device receives an incoming call message for an incoming call. The incoming call message has data indications indicating whether the incoming call is an emergency call from a public safety answering point entity. If the data indications do not indicate that the incoming call is an emergency call from the public safety answering point, then the communication device performs non-emergency call processing for the incoming call. On the other hand, if the data indications indicate that the incoming call is an emergency call, then the communication device causes the emergency call to be answered automatically.

  • Patent number: 8135406
    Abstract: A mobile device maintains a communication link with a radio access network (RAN) which is part of a generic access network (GAN). The mobile device maintains, via the GAN, a serivce connection for a voice and/or data service with a core network of a visited Public Land Mobile Network (PLMN). The mobile device operates to set and run a timer and, in response to an expiration of the timer, the mobile device sends, to a gateway controller via the RAN, a service conneciton request for a service connection with a core network of a home PLMN of the mobile device. If the service connection request is accepted, the mobile device operates to establish and maintain, via the GAN, a service connection with the core network of the home PLMN for communications.

  • Publication number: 20110300866
    Abstract: Methods are described for use in a mobile device such that when the mobile device is connected to a generic access network (GAN) cell, the mobile device receives information including characteristics pertaining to one or more neighbour cells in a network that are not GAN cells. The mobile device can then determine at least a list of candidate neighbour cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information. In some embodiments of the invention the network that is not a GAN is a UTRAN network and a candidate list of 3G cells are generated.

  • Publication number: 20110246777
    Abstract: A scheme for managing security key architecture in a network environment where a user equipment (UE) device can engage in multiple security contexts depending on the access technology. In one embodiment, when multiple security contexts are engaged and different sets of authentication vectors are created, an adapter component of the UE device manages potential interference that may be caused among the different sets of the authentication vectors as to where they are stored and which authentication vectors are used for service handovers.

  • Patent number: 7957418
    Abstract: Methods and apparatus for use in increasing data throughput to mobile stations in a wireless communication network, where data is communicated between mobile stations and the wireless network in a plurality of data bursts within time slots assigned to the mobile station. One illustrative method includes the acts of receiving, through a wireless transceiver, data in a time slot W; tuning the wireless transceiver, during a first portion of a time slot X which follows the time slot W, for transmission; reading transmit data from a transmit data queue and encoding the transmit data in a data burst in accordance with a data burst format; and causing the encoded transmit data to be transmitted in the data burst during a second portion of the time slot X. The data burst may be formatted in accordance with a predefined data burst format of the wireless network and merely shifted in time, or the data burst may be formatted in accordance with a reduced-size data burst format.

  • Patent number: 7933581
    Abstract: Methods and apparatus for use in processing disconnected emergency calls and other communications involving mobile communication devices, as well as the remote monitoring of such mobile communication devices, are disclosed. In one illustrative example, an emergency call with a public safety answering point entity is established by a mobile communication device via a wireless communication network. If the emergency call is disconnected, the mobile device monitors to receive an incoming call message for a continued emergency call from the public safety answering point entity. In response to receiving such incoming call message, the mobile device refrains from producing an audible alert and automatically answers the continued emergency call from the public safety answering point entity without detecting any manual answer signal via its user interface.
