Abstract: Different access networks may perform signaling and data delivery (bearer connection) for communication services. A device may determine, in response to a request for a service from a user of the device, whether the device is connected to a non-cellular access network. The device may transmit, when it is determined that the device is connected to the non-cellular access network, one or more control messages, relating to establishment of the service, using the non-cellular access network. The device may transmit, when it is determined that the device is not connected to the non-cellular access network, the one or more control messages, using a cellular access network. The device may establish, with a party with which the service is to connect, a bearer connection for the service over the cellular access network.

Abstract: A method and system and may receive an information request from a user device. An establishment list may be transmitted to the user device in response to the information request, wherein the establishment list includes at least one subscribing establishment. An establishment selection may be received and an establishment option associated with the establishment selection may then be transmitted to the user device. An option selection may then be received from the user device and an establishment record may be updated in response to the selected option, wherein the user device and the subscribing establishments have a pre-existing relationship within the establishment record.

Abstract: Systems and methods for providing promotional content are provided. Criteria defining a plurality of different activity-related modes for a user of a mobile station are stored. A message from the mobile station containing that contains information about an activity engaged in by the user is received through a mobile communication network. One of the activity-related modes for a user of a mobile station is selected upon determining that the information about the activity satisfies at least one criterion corresponding to the selected activity-related mode. Promotional content associated with the selected activity-related mode is obtained. The obtained promotional content is transmitted through the mobile communication network to the mobile station for presentation to the user.

Abstract: A mobile device may monitor availability of access networks that provide connectivity for the mobile device. The mobile device may also store preference information, on a per-application basis, relating to preferences for using the access networks by applications executed by the mobile device. The mobile device may additionally select, in response to a request from an application to connect to the network, one of the access networks, based on the preference information for the application; and provide a communication channel for the application using the selected access network.

The connection member includes bottom, outer and inner surfaces and a central opening. The connection member also includes a first lower protrusion that includes first and second inclined surfaces extending inwardly from the inner surface, a first slot defined in the bottom surface and the inner surface, a first lower notch defined in the inner surface, and a first opening defined in the inner surface above the first lower protrusion.

Abstract: A boring tool for digging holes having a vertical shaft of a first diameter extending from the soil surface to a suitable subsurface distance, and a void of a second diameter, larger than that of the first diameter, at the bottom, subsurface distance.

Abstract: A server may be configured to receive an indication that a first user device stores a particular content item; receive, from a second user device, a request for content; and determine that the requested content is available from the first user device. The determining may include determining that the particular content item stored by the first user device corresponds to the request for content, and determining that a local peer connection is available between the first user device and the second user device. The server may further output, to the first user device, an instruction to output the requested content to the second user device via the local peer connection, and/or the server may output, to the second user device, information which may allow the second user device to request the content from the first user device via a local peer connection.

Abstract: A server may be configured to receive behavior information associated with a user device. The behavior information may indicate a set of geographical locations at which the user device has been present. The server may generate a mode based on the behavior information. The mode may indicate a set of conditions based on which the mode is to be activated, and a set of information to be presented when the mode is activated. The server may output the mode to the user device. The user device may determine, after receiving the mode, that the set of conditions has been satisfied. The determining may be based on a geographical location of the user device. The user device may activate the mode, based on determining that the set of conditions has been satisfied; and may present at least a portion of the set of information, based on activating the mode.

Abstract: Communication sessions with mobile devices may be suspended, in a wireless communications network, after failure of one or more backhaul network links In one implementation, a device may detect failure of a backhaul network connecting a cell site to a core portion of a wireless network; and suspend, based on the detected failure, communication sessions with mobile devices connected to the cell site through radio interfaces, the suspending of the communication sessions including preventing loss of the communication sessions despite the failure of the backhaul network.
