At a first network node in a cluster of network nodes, a communication session setup request requesting setup of a communication session with a subscriber device in a plurality of subscriber devices is received. In response to receipt of the communication session setup request, registration data relating to the subscriber device is retrieved from a shared registration data store. The communication session setup request is routed according to the retrieved registration data. The retrieved registration data relating to the subscriber device was previously stored in the shared registration data store by a second network node in the cluster of network nodes in relation to a registration procedure conducted for the subscriber device by the second network node, the second network node being a different network node to the first network node in the cluster of network nodes. The network nodes of the present invention are each configured to access shared registration data store 108 for reading and writing registration data relating to subscribers in telecommunication network 100. By utilising shared registration data store 108, the requirement for a longstanding association between subscriber device 102 and a given network node in the cluster of network nodes is removed, and request message may be routed to/from subscriber device 102 by any available network node in the cluster 106. |
