A method for identifying one or more unauthorised routes used for the termination of application-to-person (A2P) short message service (SMS) messages to a mobile telecommunications network, and a system for use in performing the method. An application service is stimulated to generate an A2P SMS message 210, and to send it to a collection point 220. The message is processed to obtain an identifier identifying a source of the message (a unique network address associated with a network element used to route the message to the mobile telecommunications network, such as a Global Title, GB) 230, and it is determined whether the identifier corresponds to an authorised source of A2P SMS traffic to the network 240. Stimulating the application service to send an SMS message comprises: authenticating to the application service; entering a functional element within the service that requires delivery of an SMS message to an end user; identifying the collection point to the service; and executing the service function. Uncovers the passage of unauthorised media traffic through a network so that such traffic may be reduced or blocked. |
