1. A method for providing improved GTP path integrity assurance in a UMTS/GPRS network, the method comprising:

  • defining a path based on a first node IP address, a second node IP address and a UDP port number;

    receiving, at a first node, a first GTP message from a second node;

    extracting one or more of;

    the first node IP address, the second node IP address and the UDP Port number, from the first GTP message;

    determining an operational state of the path based on the first received message; and

    storing the operational state of the path in a path integrity protocol table, in association with the path definition and a time stamp related to a time the first GTP message was received.
