CONTROLLING COMMUNICATION MODE OF A MOBILE TERMINAL
First Claim
1. A method performed by at least one control plane node of controlling a communication mode of a mobile terminal in a mobile service chaining network, comprising:
- initiating setting of the mobile terminal in idle mode; and
submitting an instruction to at least one Internet Protocol Advertisement Point, IAP, serving the mobile terminal to invalidate context for the mobile terminal held by the at least one IAP, wherein the at least one IAP invalidates at least a registered Internet Protocol, IP, address used for the mobile terminal.

Abstract
The invention relates to methods and network nodes of controlling a communication mode of a mobile terminal in a mobile service chaining network, and managing a registered Internet Protocol (IP) address for a mobile terminal.
In a first aspect of the invention, a method performed by at least one control plane node of controlling a communication mode of a mobile terminal in a mobile service chaining network is provided. The method comprises setting the mobile terminal in idle mode and submitting an instruction to at least one Internet Protocol Advertisement Point (IAP) serving the mobile terminal to invalidate context for the mobile terminal held by the at least one IAP, wherein the at least one IAP invalidates at least a registered Internet Protocol (IP) address used for the mobile terminal.

5. A method performed by at least one control plane network node of controlling a communication mode of a mobile terminal in a mobile service chaining network, comprising:
-
receiving a query from at least one Internet Protocol Advertisement Point, IAP, serving the mobile terminal to obtain an indication of a current location of the mobile terminal from a Location Registry, LR, based on an Internet Protocol, IP, address of the mobile terminal included in the query; and initiating setting of the mobile terminal in connected mode in response to said query. - View Dependent Claims (6, 7, 8, 9, 10)

19. A control plane system comprising at least two control plane nodes configured to control a communication mode of a mobile terminal in a mobile service chaining network, each control plane node comprising a processing unit and a memory, said memory containing instructions executable by said processing unit, whereby said control plane system is operative to:
-
initiate setting of the mobile terminal in idle mode; and submit an instruction to at least one Internet Protocol Advertisement Point, IAP, serving the mobile terminal to invalidate context for the mobile terminal held by the at least one IAP, wherein the at least one IAP invalidates at least a registered Internet Protocol, IP, address used for the mobile terminal.
