Abstract: A system and method for communication service portability include the ability to receive, at an access point, a registration request for a user of an endpoint and to generate, based on the received registration request, a registration request for a wireless network authorization module, the generated registration request containing information from a user information module. The system and method also include the ability to receive a response to the generated registration request, to determine whether the generated registration request has been accepted, and to generate a response to the received registration request based on the status of the received response.

Abstract: A method and system for providing services to a communication session anchored to a micro wireless network includes providing at a router of the micro wireless network an interface for communication with a service node of a macro wireless network that is coupled to the micro wireless network. The interface is of a same type as used by a radio access network of the macro wireless network to communicate with the service node. Information associated with the session is communicated between the interface and the service node in a format used by the service node to communicate with the radio access network of the macro wireless network. The macro network provides portability services to the session of the micro wireless network through the interface.

Abstract: A method and system for providing voice calls in a macro wireless network includes providing at a router of the micro wireless network an interface for communication with a service node of a macro wireless network coupled to the micro wireless network. The interface is of a same type as is used by a radio access network of the macro wireless network to communicate with the service node. A real-time protocol communication path is established from the interface through a voice module of the service node to a public switch telephone network. Voice traffic is communicated to the public switch telephone network through the interface and the real-time protocol path.

Abstract: Disclosed are a method for media access controlling and channel time reservation system and method in distributed wireless personal area networks. A method of media access controlling for a distributed wireless network including at least one device, includes a device of the distributed wireless network, generating a data slot reservation indicator for devices of the same beacon group, and the device, broadcasting the generated data slot reservation indicator. Thus, a slot reservation for communication between devices can be completed in a shorter period of time. Also, capacity of the network can be improved by spatial reuse of channel time.

Abstract: A system for dynamically shifting beacons in a distributed wireless network and a method thereof are disclosed. In a medium access control for a wireless personal area network based on a mobile ad-hoc network, beacons are shifted to other free lower slots in order to reduce the size of a beacon period. Also, collisions that may occur during the shifting of the beacons are detected and avoided. According to the system and method, the size of the beacon period for transmitting data can sufficiently be secured by dynamically reducing the size of the beacon period without collisions.

Abstract: A power saving system in distributed wireless personal area network and a method thereof are disclosed. A PS (Power Save) anchor that provides information about hibernating devices to a beacon group through power save information elements in media access control for a wireless personal area network based on a wireless mobile ad-hoc network. Accordingly, all devices in the given wireless personal area network can schedule their active modes and hibernating modes according to hibernating intervals of destination devices with which the devices want to communicate. This can effectively reduce the necessity of the devices' waiting for the destination devices to awake from the hibernating mode as the devices maintain their idle state, and thus the power consumption of all the devices in the network can effectively be reduced.

Abstract: A method and system for managing wireless bandwidth resources include the capability to receive at a serving node a service request for a mobile unit and to communicate with a wireless network node to determine whether sufficient wireless bandwidth is available for the requested service. The method and system also include the capability to process the service request based on the availability of wireless bandwidth.
