Patent ID: 8743829

Claim:
A method for establishing or modifying a local Internet Protocol (IP) access bearer, the method comprising: receiving a handover request message transmitted by an evolved Node Base station, wherein, said handover request message carries an evolved Node Base station identifier, said evolved Node Base station includes a source evolved Node Base station or a target evolved Node Base station, said evolved Node Base station identifier is the same as a local packet data network gateway identifier; obtaining the local breakout ability of said evolved Node Base station; according to said evolved Node Base station identifier, the local breakout ability of said evolved Node Base station and a local IP access point name, establishing or modifying a local IP access bearer between a serving gateway and the local packet data network gateway, wherein said serving gateway is located in a core network or the evolved Node Base station; before receiving the handover request message transmitted from said evolved Node Base station, establishing a local IP access bearer, wherein establishing a local IP access bearer comprises: selecting the local packet data network gateway and the serving gateway, according to the local IP access point name and the home base station identifier; sending a create or modify bearer request message to said serving gateway; receiving a create or modify bearer response message returned from said serving gateway, and completing the procedure of establishing or modifying bearer between said serving gateway and the local packet data network gateway, before selecting the local packet data network gateway and the serving gateway according to the local IP access point name and the home base station identifier, the method comprises: receiving a tracking area update message transmitted by the user terminal, wherein said tracking area update message carries said local IP access point name; obtaining said home base station identifier from an allowed closed subscriber group list of the user terminal, wherein said home base station identifier represents a home base station identifier that can serve as the local IP breakout in the closed subscriber group cells that allow the UE's access; according to said local IP access point name and said base station identifier, selecting the serving gateway and the local packet data network gateway, and sending the create or modify bearer request message to said serving gateway; and receiving the create or modify bearer response message returned from said serving gateway, and completing the procedure of establishing or modifying a local IP access bearer between said serving gateway and said local packet data network gateway.
