Abstract

There is provided a method for a session audit in a communication system having a first plane and a second plane. The method can be employed in a case in which the first plane is a control plane and the second plane is a user plane, or a case in which the first plane is a user plane and the second plane is a control plane. The first plane performs operations of (1) sending to the second plane, an association update request that contains a first vendor-specific information element (IE) having (a) a bit set to indicate a desire for a single control plane (CP) fully-qualified session identification (CP F-SEID), and (b) a CP F-SEID, and (2) receiving from the second plane, an association update response that contains a second vendor-specific IE having (a) the CP F-SEID, and (b) a mapped user plane (UP) fully-qualified session identification (UP F-SEID).

Claims (32)

1. A method for a session audit in a communication system having a first plane and a second plane, wherein said method comprises said first plane performing operations of:

sending to said second plane, an association update request message that contains a first vendor-specific information element (IE) having (a) a bit set to indicate a desire for a single control plane (CP) fully-qualified session identification (CP F-SEID), and (b) a CP F-SEID for which an audit is to be done; and

receiving from said second plane, an association update response message that contains a second vendor-specific IE having (a) said CP F-SEID, and (b) a mapped user plane (UP) fully-qualified session identification (UP F-SEID).

2. The method of claim 1 , further comprising:

sending to said second plane, a subsequent message that includes a query session record IE.

3. The method of claim 1 , further comprising:

receiving from said second plane, a subsequent message that includes a query session report IE.

4. The method of claim 1 ,

wherein said CP F-SEID is a CP-generated fully-qualified session ID, and

wherein said UP F-SEID is an UP-generated fully-qualified session ID sent by said second plane within a query session report IE in a packet forwarding control protocol (PFCP) message for a requested CP F-SEID in a query session record IE.

5. The method of claim 1 , wherein said first plane is a control plane and said second plane is a user plane.

6. The method of claim 1 , wherein said first plane is a user plane and said second plane is a control plane.

7. An apparatus comprising:

electronic circuitry adapted to perform the operations of the method of claim 1 .

8. A non-transitory storage device, comprising:

instructions that are readable by a processor to cause said processor to perform the operations of the method of claim 1 .

9. A method for a session audit in a communication system having a first plane and a second plane, wherein said method comprises said first plane performing operations of:

sending to said second plane, an association update request message that contains a first vendor-specific information element (IE) having a bit set to indicate a desire for carrying out an audit for all control plane (CP) fully-qualified session identifications (CP F-SEIDs) available at said second plane; and

receiving from said second plane, an association update response message that contains multiple second vendor-specific IEs, each having (a) a CP F-SEID, and (b) a mapped user plane (UP) fully-qualified session identification (UP F-SEID) available at said second plane.

10. The method of claim 9 , further comprising:

sending to said second plane, a subsequent message that includes a query session record IE.

11. The method of claim 9 , further comprising:

receiving from said second plane, a subsequent message that includes a query session report IE.

12. The method of claim 9 ,

wherein each said CP F-SEID is a CP-generated fully-qualified session ID, and

wherein each said UP F-SEID is an UP-generated fully-qualified session ID sent by said second plane within a query session report IE in a packet forwarding control protocol (PFCP) message in a query session record IE available at said second plane.

13. The method of claim 9 , wherein said first plane is a control plane and said second plane is a user plane.

14. The method of claim 9 , wherein said first plane is a user plane and said second plane is a control plane.

15. An apparatus comprising:

electronic circuitry adapted to perform the operations of the method of claim 9 .

16. A non-transitory storage device, comprising:

instructions that are readable by a processor to cause said processor to perform the operations of the method of claim 9 .
