  • Patent number: 10728772
    Abstract: Aspects of the subject disclosure may include, for example, obtaining configuration update messages received from neighbor cells of a serving cell of a wireless network, wherein the configuration update messages include dual connectivity capability information of the neighbor cells. The neighbor cells are ranked according to the dual connectivity capability information resulting in a dual connectivity ranking. A target cell of the neighbor cells is selected according to the dual connectivity ranking and a dual connectivity capability of a mobile device, and a dual connectivity service is established according to the dual connectivity ranking. The dual connectivity service includes exchanging user plane messages between the mobile device, a master cell and a secondary cell of the wireless network. Other embodiments are disclosed.

  • Patent number: 10334510
    Abstract: Radio network technology and display thereof can be managed when multiple services and radio network technologies are available to a multi-technology mobile device. Management relies at least in part on a subscriber profile that comprises a network selection profile constructed through market policy, subscriber policy, and application policy for radio technology utilization. Network preference(s) profile is generated on per subscriber, or per subscriber type, basis and is conveyed to a subscriber station over the air. Initial subscriber profile can be delivered at a time of provisioning a multi-technology mobile device, and updated based at least upon subscriber demand, a schedule established by a network operator or service provider, or an event related to coverage area relocation or contracted services. Radio technology preferences and display of associated technologies available to a multi-technology mobile device can be controlled dynamically on a per-call and/or per-application basis.

  • Patent number: 9049631
    Abstract: Systems, methods, and apparatus that select a radio access technology based on a usage history are presented herein. A recording component can record, based on a first use of a wireless communication network, information identifying a radio access technology associated with the first use. A selection component can select, in response to receiving a request for a second use of the wireless communication network, the radio access technology for the second use based on the information. A transfer component can determine whether a request for a handover is based on a wireless service coverage. Further, the transfer component can determine whether a request for a reselection is based on the wireless service coverage. Moreover, the selection component can select another radio access technology for the second use in response to the request being based on the wireless service coverage.
