Abstract

A Subscriber Information Service Center (SISC) in a wireless telecommunications network provides location and status information about identified mobile subscribers to a requesting subscriber. The requesting subscriber may access the SISC by e-mail. The SISC retrieves the location information from the mobile subscriber'"'"'s HLR, and returns the requested information by e-mail or by posting the information on a Web site associated with the SISC. A SIP proxy in the SISC enables a second-generation mobile subscriber to request information for other mobile subscribers. The SISC may also retrieve status information from the MSC serving the mobile subscriber relating to any ongoing call by the mobile subscriber.
