| 20110286394 | PROTECTION AGAINST UNSOLICITED COMMUNICATION FOR INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM - 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. | 11-24-2011 |
| 20110289217 | PROTECTION AGAINST UNSOLICITED COMMUNICATION FOR INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM - A PUCI system is designed to process an incoming call originated by the user equipment toward the counterpart user equipment via an EMS node having a PUCI-light functionality, which includes an IBCF/I-CSCF, a S-CSCF, and a database storing the PUCI-light information.

The reason for rejection is included in a SIP BYE/ERROR message of an original session setup message, which is interpreted by a previous IMS node so as to obtain the relevant information from a SIP header. The relevant information is stored in either a global operator policy database or a local database, thus enabling a PUCI-negating IMS node to reject an unsolicited call related to the blocked session. | 11-24-2011 |
