Zusammenfassung:	A telecommunications system provides mobile internet protocol related communications services to mobile nodes via a plurality of access networks. A mobility manager directs a change of affiliation of a first mobile node between the access networks, or a change of communications session level of the mobile node, in accordance with the congestion state of the access networks, the link quality currently experienced by the mobile node, applications server messages and the level of service quality to which the first mobile node has subscribed. A quality of service for communications sessions of a mobile nodes can be maintained even on unregulated access networks, such as Wireless Local Area Networks (WLAN) independently of a Mobile IP v4/v6 stack. Moreover congested access networks can be decongested by controlling the communications bandwidth used by the mobile nodes.
