摘要
A system and method for providing lawful interception (LI) data in voice call continuity for telecommunication networks are disclosed. In one embodiment, the data associated with a registered telecommunication network user (i.e., target user) coming from a first telecommunication network is intercepted by a VCC gateway. Further, the intercepted data is sent to the LEA in a format desired by the LEA. Furthermore, the VCC gateway is configured based on a successful determination of network properties associated with the second telecommunication network upon the target user moving to the second telecommunication network. The second telecommunication network is based on a technology that is different from the first telecommunication network. In addition, the data associated with the target user coming from the second telecommunication network is continuously intercepted by the VCC gateway and continuously sent to the LEA by the VCC gateway in the format desired by the LEA.
