▪ For geographical redundancy, Operation Centers will be located at

• Seoul (1st)

• Daegu (2nd)

• Jeju (3rd)

▪ 1st & 2nd Center automatically switch over mode.

▪ 3rd Center will be only activated at most worst case.

▪ Each Operation Center will be also equipped with redundant EPC, IMS, eMBMS and MCPTT servers.
