Abstract: A geographic Hot Zone service for restricting wireless packet data sessions transmitted to/from a restricted geographic Hot Zone created within the coverage area of a wireless packet data communications network is provided. The geographic Hot Zone service is activated to create the Hot Zone during an extraordinary event and reduces the number of packet data sessions in the Hot Zone to only those involving a limited number of authorized Mobile Stations, such as those used by police, firefighters, and other emergency personnel.

Abstract: A method in one example has the steps of: registering a mobile terminal through a first RAN; receiving by a core network a first request from the mobile terminal via the first RAN and comparing a the HPLMN code of the IMSI associated with the first request with stored HPLMN codes in the core network; identifying, when a match is found between the HPLMN code of the IMSI and a respective stored HPLMN code in the core network, the mobile terminal as a home subscriber; registering the mobile terminal again through a second RAN when the mobile terminal is in the second RAN radio range; receiving by the core network a second request from the mobile terminal via the second RAN and comparing the HPLMN code of the IMSI associated with the second request with the stored HPLMN codes in the core network; regardless of the first and second HPLMN codes of the first and second RANs being different; and identifying, when a match is found between the HPLMN code of the IMSI and a further respective stored HPLMN code in the cor

Abstract: A method of generating a certified email return receipt is provided. The method includes receiving an email requiring a certified email return receipt in a locked condition, prompting a person attempting to open the email to enter certified email return receipt information, collecting the certified email return receipt information entered by the person attempting to open the email, unlocking the email thereby enabling the email to be opened after the collecting step, opening the email after the collecting step for the person who entered the certified email return receipt information, and generating a certified email return receipt certifying that the email was received by the person who entered the certified email return receipt information.

Abstract: A system and method of routing calls in a telecommunications network is provided. The method includes receiving an incoming call for the called party, determining the called party location, selecting a long distance carrier preferred by the called party for incoming calls made to the called party location, and routing the call to the called party using the selected long distance carrier. The system includes means for receiving an incoming call for the called party, means for determining the called party location, means for selecting a long distance carrier preferred by the called party for incoming calls made to the called party location, and means for routing the call to the called party using the selected long distance carrier.

Abstract: A method of censoring Internet content includes: packetizing a web page into one or more data packets (50); inserting into the data packets censorship ratings corresponding to the web page's content; conveying the data packets (50) over the Internet (30) to a receiving end user terminal (10); determining the censorship ratings of the data packets (50); and, acting on the data packets (50) in response to their determined censorship ratings.
