Abstract
A telecommunications system and method is disclosed for requiring a mobile station (MS) to notify the network of the number and/or duration of positionings performed by the MS. A service program or API (Application Program Interface), e.g., JAVA program, which is responsible for collecting information regarding the requests for location information, is either included in a Subscriber Identity Module (SIM) card, or other memory, of the MS, or downloaded to the SIM card in the MS. As a result of performing a location calculation, the API within the MS initiates a mobile originated reporting Short Message Service (SMS) or Unstructured Supplementary Service Data (USSD) message to the serving network, which includes a time stamp of the time and date the positioning request was received, the number and/or duration of the positioning(s) and the final location of MS.
