Abstract: Systems and methods for the operation of a dual mode wireless communication device are provided. A wireless communication device includes a scan module, a registration module and a learning module that cooperate to allow the device to identify available radio access technologies, select a radio interface, manage the radio interface, and learn behavioral patterns that optimize operation of the dual mode device. The dual mode device maximizes the overall time it is operational on the better radio access technology while not performing unnecessary scans. This helps in improving performance, preserving battery life and enhancing the overall user experience. In operation, the dual mode device scans for available voice or data networks upon identification of a trigger event, for example, a manual instruction, a drop in signal strength, a loss of signal, a time of usage on a particular network, a battery condition, an application preference, a state of the wireless communication device, or a geographic location.

Abstract: A multi-mode wireless terminal device includes a first network interface for communicating with a first wireless network and a second network interface for communicating with a second wireless network. The second wireless network offers services that are not necessarily provided by the first wireless network. The multi-mode wireless terminal device acts as a gateway so that wireless terminal devices operating on the first wireless network may connect to the multi-mode wireless terminal device in order to access the services of the second wireless network. The multi-mode terminal device can limit access to the services based on operational parameters such as battery power level, wireless signal strength, usage time, processing load and the like.

The acquisition list associated with the second transceiver. The exemplary method comprises updating a first category of entries of the acquisition list over a wide area network via the first transceiver and updating a second category of entries of the acquisition list by a user through input means on the wireless communication device.

Abstract: A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not on time, but rather asynchronous discrete incidents known as events. A discrete event modeling environment can be used to model a control system using one or more discrete event-driven components. The event-driven components can be used to model certain portions of a control system that cannot be accurately modeled using a time-based model.

Abstract: A communication system allows multiple, simultaneous access by a multiplicity of users to a plurality of area networks. Users are granted access to the plurality of area networks by an authentication server coupled to the plurality of area networks The authentication server retrieves a subscriber's profile information from a database coupled to the authentication server to verify that a user has a subscription to at least one of the area networks, thus allowing the user to “roam”.

Abstract: A heterogeneous wireless ad-hoc network includes a server and a number of ad-hoc service providers that provide connectivity to a network for mobile clients. The mobile client is configured to search for ad-hoc service providers with wireless backhauls to the network and associate with one of the ad-hoc service providers detected in the search based on one or more parameters.

Abstract: A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not directly on time, but rather aperiodic discrete incidents known as events. A discrete event modeling environment can be used to model a control system using one or more discrete event-driven components. The event-driven components can be used to model certain portions of a control system that cannot be accurately modeled using a time-based model.

Abstract: A system and method models regional timeout functionality in a discrete event execution environment. A timeout function is initiated associated with an entity upon occurrence of a start condition and terminated or reset upon reaching an end condition. The timeout function is configured to expire after a selected amount of time. Upon expiration of the timeout function, the entity is redirected to a predetermined location for timeout processing.

Abstract: As SIP usage becomes prolific in 3G wireless communications, challenges are presented to using the current SIP protocols for real-time communications due to the limited signaling compression offered via SIP become. Signaling introduces unwanted delays on limited bandwidth and increases the call setup time. Additionally, SIP messages are large—from a few hundred bytes to several kilobytes—and compression is not offered on all available fields. The invention provides for compression of the VIA field of SIP messages through several techniques and thereby achieves lower signaling delays that reduce complex call setup delays and reduce the loss of bandwidth to necessary in-call signaling.

Abstract: A wireless terminal concurrently associates with multiple wireless local area networks. The wireless terminal may operate in power save mode on both of the WLANs to prevent a disruption of communication on either WLAN. The wireless terminal may adjust the times at which it listens for beacons to enable reception of beacon information even though the beacons for different WLANs may overlap in time. Beacon transmission times also may be scheduled to avoid overlapping transmissions of beacons on different WLANs.
