Abstract

A protection against an unsolicited communication for an IMS (PUCI) system includes a call session control function (CSCF), and a plurality of PUCE application servers. The PUCI application servers make an evaluation as to whether a communication received from the user equipment is an unsolicited communication; the CSCF makes a decision on routing toward the PUCI application servers based on the evaluation; then, the PUCI application servers execute the routing based on the decision.
