A mobile telecommunications network including: a plurality of nodes , each of which is for wireless communication with a mobile telecommunications device ; and a respective server geographically associated with each of said nodes , each server having processing functions ; wherein a processing function of a first one of the servers geographically associated with a first one of the nodes is operable to support a communication session with the mobile telecommunications device to provide a service thereto; characterised in that the processing function of the first one of the servers is operable to send, via an X2 interface via a direct connection between the first one of the nodes and a second one of the nodes , data relating to the communication session to a second one of the servers geographically associated with the second one of the nodes for use by a processing function of the second one of the servers to enable the processing function of the second one of the servers to support the communication session and provide continuity of the communication session if the communication session moves from being supported by the processing function of the first one of the servers to being supported by the processing function of the second one of the servers ; wherein the data enables the second one of the servers to bootstrap the processing function thereof, and wherein, when the processing function of the first one of the servers sends the data relating to the communication session to the second one of the servers to support the communication session, continuity of the communication session is provided if the mobile telecommunications device moves from registration with the first one of the nodes to the second one of the nodes . a plurality of nodes , each of which is for wireless communication with a mobile telecommunications device ; and a respective server geographically associated with each of said nodes , each server having processing functions ; wherein a processing function of a first one of the servers geographically associated with a first one of the nodes is operable to support a communication session with the mobile telecommunications device to provide a service thereto; characterised in that the processing function of the first one of the servers is operable to send, via an X2 interface via a direct connection between the first one of the nodes and a second one of the nodes , data relating to the communication session to a second one of the servers geographically associated with the second one of the nodes for use by a processing function of the second one of the servers to enable the processing function of the second one of the servers to support the communication session and provide continuity of the communication session if the communication session moves from being supported by the processing function of the first one of the servers to being supported by the processing function of the second one of the servers ; wherein the data enables the second one of the servers to bootstrap the processing function thereof, and wherein, when the processing function of the first one of the servers sends the data relating to the communication session to the second one of the servers to support the communication session, continuity of the communication session is provided if the mobile telecommunications device moves from registration with the first one of the nodes to the second one of the nodes . <EOS>
