Abstract

See full text

It is presented a method for handing over a data bearer for traffic of an IFOM packet data connection between a packet data network and a mobile terminal from one access network to another access network. The method is performed in a packet data network gateway, and comprises the steps of: receiving a handover message, the handover message comprising a request to handover a source data bearer for the mobile terminal from a first access network to a second access network, wherein the first access network is a 3GPP network and the second access network is a non-3GPP network, or vice versa; transmitting a first routing rule; applying the first routing rule for downlink traffic; and establishing, when there is no matching data bearer, a new data bearer over the second access network, the new data bearer having a second routing rule matching the first routing rule.
