Lawfull call interception support |
摘要 |
Systems, methods and communication nodes according to exemplary embodiments provide for an IMS node to replicate call content for lawful call interception in packet cable networks. A CSCF node sends a command to an SBC node to perform call content replication for an identified call to be intercepted. The SBC node forwards the replicated call content to a delivery function, which in turn forwards the replicated call content to the appropriate law enforcement agency. |
