Abstract: A method and a system for implementing privacy control in a communication network are provided. The method comprises the steps of generating a first Request Verification Code (RVC) for each user request in a privacy server by means of parameter hashing or non-Parameter-hashing and forwarding the user request together with the first RVC to the SP; and verifying a second RVC and user privacy setting (s) in a privacy server, wherein the second RVC is received together with a further request from the SP. The system comprises an untrustworthy subsystem comprising at least one Service Provider (SP) for providing application service and a trustworthy subsystem comprising at least one mobile operator module for providing communication service, wherein the mobile operator module further comprises at least one mobile core network for providing user privacy control by means of Request Verification Code (RVC).

Abstract: A method (300, 400, 500) of and a message service gateway (204) for controlling delivery of a message service provided by a service provider application (202) as a value-added service to an end user having a device with messaging capability. The method (300, 400, 500) comprises the steps of determining which one of predefined categories the service provider application (202) is, and controlling the delivery of the message service to the end user based on the determined category of the service provider application (202). A system comprising at least the above message service gateway (204), a service provider application (202), one or both of a Short Message Service Center (SMSC) (206) and a Multimedia Message Service Center (MMSC) (208), and an end user having a device with messaging capability is also provided.
