Abstract: A method for automatically estimating a country where a client computer is configured to operate. The method gathers information of the client computer (e.g., GMT offset, time zone name, daylight savings status, desktop language, etc.) and estimates a country where the client computer is configured to operate using the gathered information and country estimation programming. The method may send information regarding the identity of the estimated country to a server and then receive information from the server based on the estimated country. In other embodiments, the gathered information is sent to the server and the server estimates the country where the client computer is configured to operate. In some embodiments, the country estimation programming comprises a rule engine implemented by rule programming. In some embodiments, the rule engine comprises a recursive rule program.

Abstract: A method of authenticating a user seeking access to an unlicensed wireless communication system includes delivering to an unlicensed wireless communication subscriber device licensed wireless communication system security information. An authentication result produced by the subscriber device is processed in response to the licensed wireless communication system security information. The authentication result is compared with an authentication value to selectively produce an authentication command. Unlicensed wireless communication between the subscriber device and an unlicensed wireless communication system base station is enabled in response to the authentication command.

Abstract: A method of preventing theft of service in a communication system that includes a first wireless communication system and a second wireless communication system that includes a Femtocell access point (FAP) and a network controller that can communicatively couple the FAP to the first wireless communication system. The method creates an authorized session that includes a session identify for a first user equipment (UE). The UE is recognized by the first communication as an authorized UE to use the FAP. The method rejects a request by the FAP to register a second UE when the identity of the second UE does not match any identity in the set of first UE identities. The rejected request includes the session identity of the authorized session and the identity of the second UE. The second UE is not recognized by the first communication system as an authorized UE to use the FAP.

Abstract: For a network that connects several computers, a method of determining the network bandwidth between two computers. The method measures a first time interval between when one of the computers (1) sends a first data set to the other computer and (2) receives a first response. It also measures a second time interval between when one of the computers (1) sends a second data set to the other computer and (2) receives a second response. The method then identifies the network bandwidth from the two measured time intervals.

Abstract: Some embodiments provide an architecture for establishing a multi-participant conference. This architecture has one participant's computer in the conference act as a central content distributor for the conference. The central distributor receives data (e.g., video and/or audio streams) from the computer of each other participant, and distributes the received data to the computers of all participants. In some embodiments, the central distributor receives A/V data from the computers of the other participants. From such received data, the central distributor of some embodiments generates composite data (e.g., composite image data and/or composite audio data) that the central distributor distributes back to the participants. The central distributor in some embodiments can implement a heterogeneous audio/video conference. In such a conference, different participants can participate in the conference differently. For instance, different participants might use different audio or video codecs.
