  • Patent number: 8279831
    Abstract: A system, method, and computer-readable medium are provided for choosing a network for connection and handover based on the application requirements of a multi-mode, multi-radio user equipment. The selection of the network for connectivity and handover is based on one or more of the invoking of an application, the invoking of a second application, and the closing of an application.

  • Patent number: 8126461
    Abstract: A system, method, and computer-readable medium for a communications system to manage multiple radios and protocol stacks in a network and in a user equipment are provided. When active communications takes place over one radio system, an alternate radio system is managed in such a way that promotes both low-power operations and quick handovers. When communications are idle over all of the networks, one radio network may be assigned to be a primary radio network, and the alternate radio network may be switched off provided all incoming calls are routed to the primary radio network.

  • Publication number: 20090180440
    Abstract: A communication system having a first communication device being in communication with a second communication device via a communication connectivity to a first communication network. The first communication device having a first handover module operable to handover communication connectivity from the first communication network to a second communication network. The second communication device having a second handover module cooperatively operable with the first handover module to maintain communication between the second communication device and the first communication device while the first handover module operates to handover communication connectivity from the first communication network to the second communication network.

  • Publication number: 20080102815
    Abstract: A system, method, and computer-readable medium are provided for decision-making criteria in a multi-mode, multi-radio user equipment to choose which radio network to use for connectivity and handover. Decision making depends on a number of different criteria: a user profile that specifies one or more user preference connectivity attributes, available applications of the user equipment, a service subscription of a user associated with the user equipment, a battery monitor of the user equipment, a respective link metrics indicator for each of the plurality of access networks, and application support capabilities of the plurality of access networks.
