Section: K.2.5 UE mobility
Content: A number of distinct UE mobility scenarios can be identified given the following assumptions: - multiple eNodeBs can be configured to be served by a single Local EPC; - a single dedicated PLMN-Id will be advertised by all eNodeBs operating in IOPS mode (of a given public safety authority/operator); - the TACs broadcast by cells (eNodeBs) served by different Local EPCs will be different. The mobility scenarios that can be distinguished are: 1. UE transitions from a cell controlled by the normal macro EPC to a cell operating in IOPS mode; 2. UE transitions from a cell operating in IOPS mode to a cell controlled by the normal macro EPC; 3. UE transitions from a cell operating in IOPS mode whose eNodeB is served by one Local EPC to a cell also operating in IOPS mode whose eNodeB is served by a different Local EPC (Inter-IOPS network cell transition); 4. UE transitions between cells operating in IOPS mode whose eNodeB(s) are served by the same Local EPC (Intra-IOPS network cell transition). The expected mobility behaviour in each of these scenarios is summarised in Table K.2.5-1. Table K.2.5-1: UE mobility behaviour
