User privacy management apparatus and method in mobile communications system

A user privacy management method in a Secure User Plane Location (SUPL) network including a SUPL agent, a SUPL Location Platform (SLP) and a SUPL Enabled Terminal (SET), the SLP including a SUPL Location Center (SLP) and a SUPL Positioning Center (SPC), the method comprising:

• checking a user privacy, by the SLC, on the basis of user privacy setting information when the SUPL agent requests positioning for a particular SET, and informing the SPC of information for setting a SUPL session by an internal initialization;
• transmitting a first user notification to the SET when the privacy authorization is required with respect to the SUPL agent according to the result of the checking of the user privacy in order to query whether to grant permission for the information provision;
• initiating a first SUPL session with the SET, by the SPC, and calculating the location of the SET when a first user notification response which indicates a permission for the information provision is received from the SET;
• terminating the first SUPL session, by the SPC, when the location of the SET is completely calculated, and informing the SLC of the calculated location value of the SET and the termination of the first SUPL session via an internal communication;
• checking, by the SLC, whether the privacy authorization is required with respect to the calculated location of the SET according to the result of the checking of the user privacy;
• initiating a second SUPL session with the SET, by the SLC, when the privacy authorization is required, and querying whether to transmit the location value of the SET by transmitting a second user notification to the SET;
• and
• selectively transferring the calculated location value of the SET to the SUPL agent on the basis of a second notification response received from the SET.

• initiating a second SUPL session with the SET, by the SPC, and querying whether to transmit the location value of the SET by transmitting a second user notification to the SET;
• and
• transferring a second notification response received from the SET from the SPC to the SLC, to thus selectively transfer the location value of the SET to the SUPL agent on the basis of the second notification response.
