Measures are provided for mobile relay support in relay-enhanced access networks. Such measures include setting up a first packet data connection for traffic in a relay-enhanced access network, which relates to first-type user terminals using the same access technology as a base station, from a mobile relay towards a packet data network via a first packet gateway functionality collocated with the base station currently serving the mobile relay, and setting up a second packet data connection for traffic in the relay-enhanced access network, which relates to second-type user terminals using another access technologies as the base station and the mobile relay, from the mobile relay towards the packet data network via a second packet gateway functionality external to the base station currently serving the mobile relay.
