Embodiments of the invention relate to methods and apparatus for adapting the IKE/IPsec peer status time interval in accordance with the service delivered to the UE. The peer status time interval is used to detect IKE/IPsec peer liveliness in the UE. The evolved Packet Data Gateway, ePDG, sets the peer status time interval according to the type of bearers or GTP tunnels established with the PDN GW. The ePDG uses a default peer status interval T1 when the ePDG connects the UE to the PDN using the default GTP tunnel established at the time of PDN connection establishment. When a multimedia service is established for the UE, one or more dedicated GTP tunnels of different quality of service requirements may be established at the ePDG. The ePDG would then use a different peer status time interval T2 that may be derived from the quality of service parameters associated with the one or more dedicated GTP tunnels.
