摘要： There is provided a method for handling subscriptions from a subscriber node (700) to changes in data relating to a user held at a database node (900) in a telecommunications system. At the subscriber node (700) a subscribe message is prepared (S1) comprising: first information identifying first data which the subscriber node (700) wishes to receive in a notification message in response to a change to the first data; second information identifying second data which the subscriber node (700) wishes to receive with such a notification message; and third information, different to the first information, specifying a condition to be fulfilled in relation to third data before such a notification message is sent. The first, second and third data each relate to the user and are held at the database node (900). The subscribe message is sent (S2) towards the database node (900). The subscribe message sent from the subscriber node (700) is received (S3) at the database node (900). The subscribe message received at the database node (900) comprises the first, second and third information. At the database node (900) a change to the first data identified by the received first information is detected (S4). In response to the detecting of such a change, and if it is determined (S5) that the condition specified in the received third information has been fulfilled, one or more notification messages is/are sent (S6) from the database node (900) towards the subscriber node (700). The notification message or messages comprise(s): the first data following the detected change; and the second data specified by the received second information.
