Configuration of liveness check timeout using ike messages

Abstract

There is provided mechanisms for configuration of liveness check using Internet key exchange messages. A method is performed by a user equipment. The method comprises transmitting, to a core network node, a first Internet key exchange message comprising a configuration attribute indicating support of receiving a timeout period for liveness check. The method comprises receiving, from the core network node, a second Internet key exchange message comprising a configuration attribute indicating a timeout period for said liveness check.

Description

technical field [0001] Embodiments presented herein relate to liveness checks, in particular to methods, user equipment, core network nodes, computer programs and computer program products for configuring liveness checks using Internet key exchange messages. Background technique [0002] In a communication network, it can be a challenge to obtain good performance and capacity for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed. [0003] One parameter to provide good performance and capacity for a given communication protocol in a communication network is, for example, to provide efficient and reliable activity on untrusted non-3GPP access networks (where 3GPP is an acronym for 3rd Generation Partnership Project) The ability to check for consistency (also known as dead peer detection). [0004] Liveness checks ensure that both ends of an Internet Key Exchange (eg, Internet Key Exchange v1 (IKEv1) or ...

AI Technical Summary

Problems solved by technology

[0008] User equipment can send information request messages to monitor ePDG activity, but the operator has no control over the timeout

Therefore, there is limited possibility for the network to control the practical use of liveness checks from user equipment
