System And Method For Lawful Interception In Voice Call Continuity For Telecommunication Networks
Abstract: 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.

Specification
BACKGROUND
Even with the advancement of telecommunication networks towards long term evolution (L TE) and other such advanced technologies there is still a requirement for maintaining call continuity across various networks. Further the term "network convergence" is becoming very popular in the advanced telecommunication networks. Furthermore the concept of "voice call continuity" (VCC) is starting to emerge from a cell-to-cell movement towards a network-to-network movement. The VCC requires maintaining a voice call during the network-to-network movement when the telecommunication networks are based on various technologies. For example the VCC requires seamlessly maintaining a voice call when a user/subscriber moves from one telecommunication network that is based on one technology for example a second generation (2G) network or a WiMax based network to another telecommunication network that is based on another technology for example a third generation (3G) network or a Wi-Fi based network.
