Abstract

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.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a technology for accessing a packet data network. Background technique [0002] Femtoce11 (home base station) system architecture includes a wireless access point device that provides wireless access functions, usually called Femto AP (Access Point, access point); AP accesses the Internet through broadband access routers or DSL Modem and other devices , and connect to your mobile operator's network. Under the LTE (LongTerm Evolution, Long Term Evolution) network architecture in the 3GPP (the3rd Generation Partner Project) network, the access point is called HeNB (Home EvolvedNodeB); in UTRAN (UMTS Territorial Radio Access Network, UMTS terrestrial wireless access network) network organization, the access point is called HNB (Home Node B). [0003] Under the Femtoce11 architecture, such as figure 1 As shown, since there are two connection modes between HNB / HeNB and PDN (Packet...
