METHOD, DEVICE AND SYSTEM FOR ACCESSING TO PACKET DATA NETWORK

摘要

A method and an apparatus for accessing a Packet Data Network (PDN) are disclosed. The present invention relates to network technologies and is intended to this problem in the prior art: The Serving GPRS Supporting Node (SGSN) is unable to decide whether the User Equipment (UE) will access the PDN through a Home NodeB (HNB)/Home evolved NodeB (HeNB) directly or through a Gateway GPRS Supporting Node (GGSN)/PDN Gateway (GW). The method for accessing a PDN includes: obtaining access information; and selecting a Network Element (NE) to access the PDN through a Gi/SGi interface.
