The terminal performs continuous measurements on its own and neighboring cells and send measurement reports when required. Once the measurement report is sent the serving eNB can take a handover decision and start the handover preparation phase.

IMS security is divided into access security (specified in 3GPP TS 33.203 [28]) and network security (specified in 3GPP TS 33.210 [29]). Access security (which we describe in Section 12.1) includes authentication of users and the network, and protection of the traffic between the IMS terminal and the network. Network security (which we describe in Section 12.2) deals with traffic protection between network nodes, which may belong to the same or to different operators.
