Abstract: A method includes: a network authentication server receiving a call request message from a calling device, where the call request message includes a first user identity of a calling user and a call authentication identifier; the network authentication server sending a call authentication request to an enterprise authentication server corresponding to the first user identity, where the call authentication request includes the call authentication identifier; the network authentication server receiving a call authentication success indication from the enterprise authentication server, where the call authentication success indication indicates that authentication succeeds; and the network authentication server sending target data to a called device, where the target data includes identity information of the calling user and/or information of an enterprise to which the calling user belongs.

Abstract: The embodiment of the present invention discloses an implementation method of IMS interception, a system and a device thereof. The method includes allocating media anchor points to communication parties; and copying communication content to complete interception of the communication content when the communication parties communicate through the media anchor points. In the present invention, the interception of the communication content can be implemented on the media anchor points instead of the existing media access equipment, thus implementing centralized interception of a media on an IMS network, and ensuring that users accessing the IMS network in various modes can implement the centralized interception of the media on an IMS core without requirement for access side equipment or an extended private interface between the IMS core and the access side equipment.

Abstract: A method for implementing a service triggered by off-hook includes: sending information of a service triggered by off-hook which is subscribed by a user to a service implementing server; carrying out an operation of the service triggered by off-hook according to the information of the service triggered by off-hook when the user is off-hook. The embodiments of the present invention also provide a system for implementing a service triggered by off-hook. In accordance with the embodiments of the present invention, the service implementing server may carry out the operation of the service triggered by off-hook according to a subscription type of the user to implement the service triggered by off-hook.
