1. A method of sharing measurement data between a first node and a second node, the measurement data having been acquired by the first node and relating to an event associated with a handover mechanism or a SIP signalling transaction in a communications network the method comprising:
- selecting a signalling packet to be sent from the first node to the second node as part of a process related to the handover mechanism or the SIP transaction, the signalling packet having a data structure definition associated therewith; and
incorporating the measurement data in the signalling packet in accordance with the data structure definition prior to sending the signalling packet to the second node.

Abstract
Data are recorded relating to an event associated with a handover mechanism, the data being shared between a Home Agent and a Mobile Node by communicating the collected data using an extension header of a packet communicated between the Home Agent and the Mobile Node as part of the handover mechanism.

13. A network node apparatus for participating in a handover mechanism or a SIP signalling transaction in a communications network, the apparatus comprising:
-
a data store;
a processing resource arranged to provide;
a measurement recorder for recording measurement data relating to an event associated with the handover mechanism or the SIP transaction in the data store;
a packet selector for identifying a signalling packet forming part of a process related to the handover mechanism or the SIP transaction and to be sent, when in use, to another node participating in the handover mechanism or the SIP transaction, the signalling packet having a data structure definition capable of supporting incorporation of additional information in the signalling packet;
a message modifier for incorporating the measurement data in the signalling packet in accordance with the data structure definition of the signalling packet; and
a packet forwarder for forwarding the signalling packet to the another node.

14. A network node apparatus for participating in a handover mechanism or a SIP signalling transaction in a communications network, the apparatus comprising:
-
a data store;
a processing resource arranged to provide;
a message receiver for receiving a signalling packet forming part of a process related to the handover mechanism or the SIP transaction and incorporation of measurement data therein by virtue of a data structure definition of the signalling packet, the measurement data relating to an event associated with the handover mechanism or the SIP transaction;
a measurement extractor for extracting the measurement data from the signalling packet; and
a data recorder for recording the measurement data in the data store.

15. A system for sharing measurement data between a first node and a second node, the measurement data having been acquired, when in use, at the first node and relating to an event associated with a handover mechanism or a SIP signalling transaction in a communications network, the system comprising:
-
a packet selector for selecting a signalling packet to be sent from the first node to the second node as part of a process related to the handover mechanism or the SIP transaction, the signalling packet having a data structure definition associated therewith; and
a packet modifier for incorporating the measurement data in the signalling packet in accordance with the data structure definition prior to sending the signalling to the second node. - View Dependent Claims (16)
