Abstract

A method and a Lawful Intercept, LI, management module for LI configuration of an Internal Interception Function, IIF, which is hosted by a Virtual Network Function, VNF, in a cloud based network and for keeping a LI administration mediation function, ADMF, in a LI system, updated regarding the current LI configuration in the cloud based network. The method comprises receiving a notification comprising a VNF and its VNF characteristics, making LI configuration decisions based on VNF characteristics and a LI policy from a LI policy database, performing a LI configuration of the VNF and the IIF in accordance with configuration decisions, storing the VNF/IIF characteristics in the LI policy database, if configuration was successful, and updating the LI ADMF about new LI configuration of the cloud based network.

First claim

1 . A method in a Lawful Intercept (LI) management module for LI configuration of an Internal Interception Function (IIF) hosted by a Virtual Network Function (VNF) in a cloud based network and for keeping a LI administration mediation function (ADMF) in a LI system updated regarding the current LI configuration in the cloud based network, the method comprising:
receiving a notification comprising a VNF and its VNF characteristics; making LI configuration decisions based on VNF characteristics and a LI policy from a LI policy database; performing LI configuration of the VNF and the IIF (VNF/IIF) in accordance with the LI configuration decisions; storing VNF/IIF characteristics in the LI policy database, if configuration was successful; and updating the LI ADMF about a new LI configuration of the cloud based network.

2 . The method according to claim 1 , wherein performing LI configuration of the VNF/IIF further comprises deciding to start LI configuration of the VNF if LI is needed and allowed.

3 . The method according to claim 1 , wherein the performing LI configuration of the VNF/IIF further comprises:
checking if the IIF is embedded in a VNF node; and ordering an orchestrator of the cloud based network to create a new VNF/IIF.

4 . The method according to claim 1 , wherein the method further comprises checking if configuration of the VNF/IIF is OK or not.

5 . The method according to claim 1 , wherein the notification is received from an OSS/BSS.

6 . The method according to claim 3 , wherein the notification is received from the cloud orchestrator.

7 . A Lawful Intercept (LI) system comprising:
a LI administration mediation function (ADMF); a LI policy database; a LI management module for LI configuration of an Internal Interception Function (IIF) hosted by Virtual Network Function (VNF) in a cloud based network and for keeping a LI ADMF updated regarding the current LI configuration in the cloud based network, the LI management module comprising a processing circuitry configured to: receive a notification comprising a VNF and its VNF characteristics; make LI configuration decisions based on the VNF characteristics and a LI policy from the LI policy database; perform LI configuration of the VNF and the IIF (VNF/IIF) in accordance with the LI configuration decisions; store VNF/IIF characteristics in the LI policy database, if configuration was successful; and update the LI ADMF about a new LI configuration of the cloud based network.

8 . The LI system according to claim 7 , wherein performing LI configuration of the VNF/IIF further comprises:
deciding to start LI configuration of the VNF if LI is needed and allowed.

9 . The LI system according to claim 7 , wherein performing LI configuration of the VNF/IIF further comprises:
checking if IIF is embedded in the VNF node; and ordering an orchestrator of the cloud based network to create a new VNF/IIF.

10 . The LI system according to claim 7 , wherein performing LI configuration of the VNF/IIF further comprises:
checking if configuration of VNF/IIF is OK or not.

11 . The LI system according to claim 7 , wherein the notification is received from an OSS/BSS.

12 . The LI system according to claim 9 , wherein the notification is received from the cloud orchestrator.
