Selective event reporting in a mobile telecommunications network

A method of event reporting between a first node (30;

• 42;
• 44) and a second node (30;
• 46;
• 50) of a mobile telecommunications network, the method comprising:
• the second node (30;
• 46;
• 50) sending to the first node (30;
• 42;
• 44) an indication specifying that a change in type of radio access technology used by a user equipment (10) for connecting to the telecommunications network is to be reported from the first node (30;
• 42;
• 44) to the second node (30;
• 46;
• 50);
• and
• the second node (30;
• 46;
• 50) sending to the first node (30;
• 42;
• 44) additional information specifying at least one type of radio access technology;
• and
• in response to a change of the user equipment (10) to or from said at least one type of radio access technology, the second node (30;
• 46;
• 50) receiving a report of the detected change in type of radio access technology from the first node (30;
• 46;
• 50).

• 46;
• 50) a second information element comprising additional information for specifying a subtype of the event to be reported, the second information element being associated with the first information element by comprising an indication of the type of event specified in the first information element;
• and
• in response to the first node (30;
• 42;
• 44) detecting the event of said type and subtype, the first node (30;
• 42;
• 44) sending a report of the detected event to the second node (30;
• 46;
• 50).
