System and method for lawful interception in voice call continuity for telecommunication networks

A non-transitory computer-readable medium having stored thereon instructions for providing voice call continuity (VCC) for lawful interception (LI) data comprising machine executable code which, when executed by a processor, causes the processor to perform steps comprising:

• receiving a first duplicate of data associated with a voice call initiated by a user over a first telecommunication network in response to a first duplication request;
• detecting a movement of the user from the first, telecommunication network to a second telecommunication network during the voice call;
• determining one or more network properties associated with the second telecommunication network;
• reconfiguring one or more network properties of a VCC device based on the determined one or more network properties associated with the second telecommunication network;
• receiving a second duplicate of the data associated with the voice call from the second telecommunication network in response to a second duplication request;
• and
• delivering the received first, and second duplicates of the voice call as the LI data to a law enforcement agency (LEA).

A voice call continuity (VCC) device comprising

• a processor;
• and
• a memory coupled to the processor configured to execute programmed instructions stored in the memory comprising:
• receiving a first duplicate of data associated with a voice call initiated by a user over a first telecommunication network in response to a first duplication request;
• detecting a movement of the user from the first telecommunication network to a second telecommunication network during the voice call;
• determining one or more network properties associated with the second telecommunication network;
• reconfiguring one or more network properties of the VCC device based on the determined one or more network properties associated with the second telecommunication network;
• receiving a second duplicate of the data associated with the voice call from the second telecommunication network in response to a second duplication request;
• and
• delivering the received first and second duplicates of the voice call as the LI data to a law enforcement agency (LEA).
