Zusammenfassung:PROBLEM TO BE SOLVED: To provide a system and method that conducts forced default routing of a call. SOLUTION: A communication network 1 includes a signal transfer point 10 that receives an initial address message from a service switch point 12. A signal transfer point 10 decides whether or not a transfer call identifier (FCI) in 'm'-bits to indicate a local number portability(LNP) collation is set. In the case that the FCI 'm'-bits are set, the signal transfer point 10 conducts usual call processing. In the case that the FCI 'm'-bits are not set, the signal transfer point 10 sets the FCI 'm'-bits to '1' before usual processing is performed if a database inquiry signal is not active.
