Abstract

Systems and methods are provided for notifying third-party servers, such as law enforcement agency servers, of updates to wireless user equipment identifiers. The method includes receiving a replacement wireless user equipment identifier to replace a current wireless UE identifier. It is determined that a third-party server (law enforcement agency) information request is associated with the current wireless UE identifier (such as an IMEI or PEI). Responsive to determining there is an information request from a third-party server associated with the current wireless UE identifier, notification of the replacement wireless user equipment identifier is generated and transmitted to the third-party server.

Claims (33)

1 . A system, the system comprising:

one or more hardware processors configured by machine-readable instructions to:

receive a replacement wireless user equipment (UE) identifier to replace a current wireless UE identifier;

determine a third-party server information request is associated with the current wireless UE identifier;

responsive to determining the third-party server information request is associated with the current wireless UE identifier, generate an X 1 interface notification of the replacement wireless UE identifier to a third-party server; and

transmit, via an X 1 interface, the X 1 interface notification of the replacement wireless UE identifier to the third-party server of the third-party server information request.

2 . The system of claim 1 , wherein the X 1 interface notification generated identifies the replacement wireless UE identifier and the current wireless UE identifier.

3 . The system of claim 1 , wherein the one or more hardware processors are further configured by machine-readable instructions to:

transmit the X 1 interface notification of the replacement wireless UE identifier to an agent server of the third-party server.

4 . The system of claim 1 , wherein a lawful interception management system transmits the X 1 interface notification of the replacement wireless user equipment identifier to an agent server of the third-party server.

5 . The system of claim 1 , wherein the third-party server is a server of a law enforcement agency (LEA).

6 . The system of claim 5 , wherein the third-party server information request from the third-party server was made by the server of the LEA.

7 . A method, the method comprising:

receiving a replacement wireless user equipment (UE) identifier to replace a current wireless UE identifier;

determining a third-party server information request is associated with the current wireless UE identifier;

responsive to determining the third-party server information request associated with the current wireless UE identifier, generating an X 1 interface notification of the replacement wireless user equipment identifier to a third-party server; and

transmitting, via an X 1 interface, the X 1 interface notification of the replacement wireless UE identifier to the third-party server of the third-party server information request.

8 . The method of claim 7 , wherein the X 1 interface notification generated identifies the replacement wireless UE identifier and the current wireless UE identifier.

9 . The method of claim 7 , further comprising:

transmitting the X 1 interface notification of the replacement wireless user equipment identifier to an agent server of the third-party server.

10 . The method of claim 7 , wherein a lawful interception management system transmits the X 1 interface notification of the replacement wireless user equipment identifier to an agent server of the third-party server.

11 . The method of claim 10 , wherein the third-party server is a server of a law enforcement agency.

12 . The method of claim 11 , wherein the third-party server information request from the third-party server was made by the server of the LEA.

13 . A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method, the method comprising:

receiving a replacement wireless user equipment identifier to replace a current wireless UE identifier;

determining a third-party server information request is associated with the current wireless UE identifier; and

responsive to determining the third-party server information request associated with the current wireless UE identifier, generating an X 1 interface notification of the replacement wireless user equipment identifier to a third-party server; and

transmitting, via an X 1 interface, the X 1 interface notification of the replacement wireless UE identifier to the third-party server of the third-party server information request.

14 . The non-transient computer-readable storage medium of claim 13 , wherein the X 1 interface notification generated identifies the replacement wireless UE identifier and the current wireless UE identifier.

15 . The non-transient computer-readable storage medium of claim 13 , wherein the method further comprises:

transmitting the X 1 interface notification of the replacement wireless user equipment identifier to an agent server of the third-party server.

16 . The non-transient computer-readable storage medium of claim 13 , wherein a lawful interception management system transmits the X 1 interface notification of the replacement wireless user equipment identifier to an agent server of the third-party server.

17 . The non-transient computer-readable storage medium of claim 16 , wherein the third-party server is a server of a law enforcement agency.
