Abstract

Embodiments of the present disclosure provide method and apparatus for monitoring event configuration. A method performed by a first mobile management node comprises receiving information regarding a first interworking service capability exposure function (IWK-SCEF) from a second mobile management node. The method further comprises determining whether the first mobile management node and the second mobile management node use a same IWK-SCEF based on the information regarding the first IWK-SCEF. The method further comprises sending an indication of whether the first mobile management node and the second mobile management node use the same IWK-SCEF to the second mobile management node.

First claim

What is claimed is:

1 . A method performed by a first mobile management node, comprising:
receiving information regarding a first interworking service capability exposure function (IWK-SCEF) from a second mobile management node; determining whether the first mobile management node and the second mobile management node use a same IWK-SCEF based on the information regarding the first IWK-SCEF; and sending an indication of whether the first mobile management node and the second mobile management node use the same IWK-SCEF to the second mobile management node, wherein the indication is comprised in at least one of:
a Context Acknowledge message;
a Forward Relocation Response; or
a Forward Relocation Complete Notification message.

2 . The method according to claim 1 , wherein the step of receiving and determining are performed during a mobility procedure of a terminal device moving from the first mobile management function to the second mobile management function.

3 . The method according to claim 2 , wherein the mobility procedure comprises at least one of a tracking area update procedure or a handover procedure.

4 . The method according to claim 2 , further comprising:
in response to a determination that the first mobile management node and the second mobile management node use the same IWK-SCEF, skipping sending a deletion notification of a monitoring event configuration related to the terminal device to the same IWK-SCEF; or in response to a determination that the first mobile management node and the second mobile management node do not use the same IWK-SCEF, sending the deletion notification of the monitoring event configuration related to the terminal device to the IWK-SCEF used by the first mobile management node.

5 . The method according to claim 4 , wherein the deletion notification of the monitoring event configuration is comprised in an inform IWK-SCEF message.

6 . The method according to claim 1 , wherein the step of receiving and determining are performed during a mobility procedure of a terminal device moving from the second mobile management function to the first mobile management function.

7 . The method according to claim 6 , wherein the mobility procedure comprises at least one of a tracking area update procedure or a handover procedure.

8 . The method according to claim 6 , wherein the information regarding the first IWK-SCEF is comprised in at least one of:
a Context Response; or a Forward Relocation Request.

9 . The method according to claim 6 , further comprising:
selecting an IWK-SCEF based on the information regarding the first IWK-SCEF.

10 . The method according to claim 9 , wherein selecting the IWK-SCEF based on the information regarding the first IWK-SCEF comprises:
selecting the same IWK-SCEF as the IWK-SCEF used by the second mobile management node.

11 . The method according to claim 1 , wherein when the second mobile management node uses the first IWK-SCEF, the information regarding the first IWK-SCEF comprises the Diameter HOST and REALM information of the first IWK-SCEF.

12 . The method according to claim 1 , wherein determining whether the first mobile management node and the second mobile management node use the same IWK-SCEF based on the information regarding the first IWK-SCEF comprises:
when the first mobile management node uses the first IWK-SCEF and the information regarding the first IWK-SCEF indicates that the second mobile management node uses the first IWK-SCEF, determining that the first mobile management node and the second mobile management node use the same IWK-SCEF; when the first mobile management node uses another IWK-SCEF and the information regarding the first IWK-SCEF indicates that the second mobile management node uses the first IWK-SCEF, determining that the first mobile management node and the second mobile management node do not use the same IWK-SCEF; or when the first mobile management node uses the first IWK-SCEF and the information regarding the first IWK-SCEF indicates that the second mobile management node does not use any IWK-SCEF, determining that the first mobile management node and the second mobile management node do not use the same IWK-SCEF.

13 . The method according to claim 1 , wherein the first mobile management node comprises serving general packet radio service support node (SGSN) or mobile management entity (MME).

14 . A method performed by a second mobile management node, comprising:
sending information regarding a first interworking service capability exposure function (IWK-SCEF) to a first mobile management node; and receiving an indication of whether the first mobile management node and the second mobile management node use the same IWK-SCEF from the first mobile management node, wherein the indication is comprised in at least one of:
a Context Acknowledge message;
a Forward Relocation Response; or
a Forward Relocation Complete Notification message, and
wherein the information regarding the first IWK-SCEF is used to determine whether the first mobile management node and the second mobile management node use a same IWK-SCEF.

15 . The method according to claim 14 , wherein the step of sending is performed during a mobility procedure of a terminal device moving from the first mobile management function to the second mobile management function.

16 . The method according to claim 15 , wherein the mobility procedure comprises at least one of a tracking area update procedure or a handover procedure.

17 . The method according to claim 14 , wherein the step of sending is performed during a mobility procedure of a terminal device moving from the second mobile management function to the first mobile management function.

18 . The method according to claim 17 , wherein the mobility procedure comprises at least one of a tracking area update procedure or a handover procedure.

19 . The method according to claim 17 , further comprising:
in response to the first mobile management node and the second mobile management node use the same IWK-SCEF, skipping sending a deletion notification of a monitoring event configuration related to the terminal device to the same IWK-SCEF; or in response to the first mobile management node and the second mobile management node does not use the same IWK-SCEF, sending the deletion notification of the monitoring event configuration related to the terminal device to the IWK-SCEF used by the second mobile management node.

20 . The method according to claim 19 , wherein the deletion notification of the monitoring event configuration is comprised in an inform IWK-SCEF message.

21 . The method according to claim 14 , wherein when the second mobile management node uses the first IWK-SCEF, the information regarding the first IWK-SCEF comprises the Diameter HOST and REALM information of the first IWK-SCEF.

22 . A first mobile management node, comprising:
a processor; and a memory coupled to the processor, said memory containing instructions executable by said processor, whereby said first mobile management node is operative to:
receive information regarding a first interworking service capability exposure function (IWK-SCEF) from a second mobile management node;
determine whether the first mobile management node and the second mobile management node use a same IWK-SCEF based on the information regarding the first IWK-SCEF; and
send an indication of whether the first mobile management node and the second mobile managemen
