Abstract: An apparatus in one example may have a functionality of a policy decision function divided into two parts; one part representing a home network application function and the other part representing visited network bearer resources and local policies. The one part of the policy decision function supports communications with the application function, and represents the home network and application in a request for QoS control to the visited network. The other part of the policy decision function supports visited network interactions with a policy enforcement function, and represents visited network local policy related to resource utilization and roaming agreement-based policy.

Abstract: The invention concerns a method and a system for rapidly establishing a communication, particularly a Bluetooth type communication, between at least one reader and a plurality of communicating objects. Each communicating object and said reader have a communication protocol. Each communicating object has a communication address. The method comprises: the step of defining a unique communication address for all of the communicating objects; the step, for said reader, of determining whether at least one communicating object is present in the environment in which said reader is located, by sending a request to the unique communication address of all the communicating objects; the step, for each communicating object that receives said request, of revealing its presence to said reader by sending a response signal that is time-shifted relative to the response signals sent by the other communicating objects.

The communication circuit also includes a second sub-circuit which produces first and second single-ended replica transmission signals which together substantially comprise a replica of the first differential signal component of the composite differential signal and a third sub-circuit, which is coupled to the first and second sub-circuits, and which produces the differential replica transmission signal from the first and second single-ended replica transmission signals.

Abstract: A method of transmitting information over a feed back channel of a communication system that has multiple antenna systems is provided. Long term channel condition information is obtained from received measured and/or calculated channel parameter values. The obtained long term channel condition information is arranged in a particular manner and transmitted over a defined time period during which the long term channel condition information varies relatively slowly. Because the long term information remains relatively constant for one or more defined time periods, the amount of bandwidth needed to communicate this value is small because it need only be communicated occasionally. Thus only a small bandwidth needs to be allocated for transmitting this long term information.

According to the method and apparatus, communication is allowed between wireless devices belonging to different coordinator-based wireless networks through wired/wireless connecting devices using physical addresses, whose uniqueness is ensured across the whole network, instead of using ID information assigned by a PNC, as physical addresses of a destination network device and a source belonging to different coordinator-based wireless networks.

Abstract: To assist an operator to position a wireless camera so that a base station receives with good quality a radiofrequency signal transmitted from a transmitter linked to the camera, several measurers linked to diversity receivers of the signal each determine whether a characteristic of the signal via the respective receiver satisfies a reception criterion. In the base station, a counter counts the receivers satisfying the reception criterion, and a divider establishes a reception quality indicator dependent on the number of satisfactory receivers so as in particular to retransmit it via a return channel to the camera so that it can be displayed thereon.

Abstract: A system and method for preventing a wireless controller system and WiFi radio system within a console from interfering with each other. The WiFi system is prevented from activating its transmitter during the controller receive times by detecting a signal sent to the WiFi module indicating where the controller receive times occur. Based upon the state of the signal, the WiFi transmission algorithm can determine the appropriate times to turn on and off the WiFi transmitter in concert with the defined 802.11 media access protocol. Furthermore, the WiFi module provides its operating channel information to the controller radio system to avoid using the WiFi channel for any communications.
