Abstract: Methods, systems, and computer programs for trusted communication among mobile devices are described. In some aspects, information is wirelessly transmitted from a first mobile device to a second mobile device. The information permits the second mobile device to detect proximity of the first mobile device. In some implementations, the information can be wirelessly transmitted by a proximity-activated wireless interface, such as, for example, a Near Field Communication (NFC) interface. In response to the information, the first mobile device receives a message and a first authentication value wirelessly transmitted from the second mobile device to the first mobile device. A second authentication value is generated at the first mobile device based on the message and the shared secret value. Integrity of the message is verified based on comparing the first authentication value and the second authentication value.

Abstract: A wireless communication system (100) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices (114) within the communication system (100) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device (114) as they are received until all parts of the signaling message have been received.

Abstract: A communication system comprising a mobile station and a network implements a persistent packet data control channel that provides for a continuous exchange of control information, such as system information (SI) messages and handoff-related information. The mobile station implements the persistent packet data control channel by mapping the persistent packet data control channel to a packet associated control channel when a packet associated control channel is available and to a virtual associated control channel when a packet associated control channel is not available. The virtual associated control channel allows the mobile station to pass control information to network in the absence of an uplink Temporary Block Flow (TBF).

Abstract: The present invention provides a communication controller and a method for maintaining a communication connection during a cell reselection. The communication connection is maintained by changing between a first operating mode, such as a packet data mode, which does not support the maintenance of a communication connection throughout a cell reselection, and a second operating mode, such as a circuit switched mode, which does support maintenance of a communication connection during a handover. Use of a virtual mobile switching center in the base station subsystem facilitates the conversion and routing of circuit switched data, transmitted between the mobile subscriber and the base transceiver station, to the packet data network while in a circuit switched mode.

Abstract: The present invention provides a method for managing in a mobile subscriber the traffic flow of a communication connection during a cell reselection. The method includes communicating via a communication connection with a first cell, and monitoring communication conditions, while communicating with the first cell.

The mobile subscriber then establishes a communication connection with the second cell, while maintaining the communication connection with the first cell.
