INTERNAL SWITCHING METHOD AND DEVICE FOR HIGH RATE PACKET DATA SERVING GATEWAY

摘要

Disclosed are an internal switching method and device for a high rate packet data serving gateway. The method comprises: a target high rate packet data serving gateway (T-HSGW) receiving a switching response message from a source high rate packet data serving gateway (S-HSGW), wherein the switching response message carries PDN unique identification information about each PDN connection between the S-HSGW and a packet data network (PDN); and the T-HSGW establishing a PDN connection between the T-HSGW and the PDN according to the PDN unique identification information. By means of the present invention, a T-HSGW can quickly locate to all of the PDN connections and reestablish a connection, thereby realizing Inter-HSGW switching under an MUPSAP scene.
