Abstract
Techniques for enabling handoff for multiple packet data network connection include selecting, when roaming from a current access network (AN) supporting multiple concurrent packet data network (PDN) connections to a handover target AN not supporting multiple concurrent PDN connections, a single PDN connection, from among multiple active PDN connections, for operation in the handover target AN and exchanging messages to register the single PDN connection in the handover target AN.
