摘要： A PUCI system is designed to process an incoming call originated by the user equipment toward the counterpart user equipment via an IMS node having a PUCI-light functionality, which includes an IBCF/I-CSCF, a S-CSCF, and a database storing the PUCI-light information. Through a query to the database indicating a suspicious session in relation to the incoming call, the IMS node immediately blocks the suspicious session or simply marks the suspicious session for the further processing at a subsequent node. 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.
摘要翻译： PUCI系统被设计为经由具有PUCI-light功能的IMS节点处理由用户设备发起的来话给对方的用户设备，该IMS节点包括IBCF / I-CSCF，S-CSCF和存储 PUCI-light信息。通过对数据库的查询指示相对于来话呼叫的可疑会话，IMS节点立即阻止可疑会话，或简单地标记可疑会话，以便在后续节点进一步处理。拒绝的原因包括在原始会话建立消息的SIP BYE / ERROR消息中，由先前IMS节点解释，以便从SIP报头获得相关信息。相关信息存储在全局运营商策略数据库或本地数据库中，从而使PUCI否定IMS节点能够拒绝与被阻塞会话相关的主动呼叫。
