Method and system for information transmission

摘要

The present invention discloses a method and system for information transmission. Said method includes: an Evolved Packet Data Gateway (ePDG) notifying a Policy and Charging Rules Function (PCRF) entity of the location information of a User Equipment (UE); the PCRF entity sending the location information of the UE to a Broadband Policy Control Function (BPCF) entity. The method and system provided by the present invention solve the problem that the BPCF in a fixed network can not initiate an S9* session to the PCRF entity.

1. A method for information transmission, comprising:
an evolved packet data gateway (ePDG) notifying a policy and charging rules function (PCRF) entity of location information of a user equipment (UE);
the PCRF entity establishing a S9 session with a broadband policy control function (BPCF) entity; the PCRF entity sending the location information of the UE to the BPCF entity using the S9 session; wherein, the location information comprises an identifier and tunnel information of the UE, the UE identifier comprises a fixed network access identifier of the UE, and the tunnel information comprises local IP address information of the UE; wherein, after the step of the PCRF entity sending the location information of the UE to the BPCF entity using the S9 session, the ePDG entity sends an internet protocol security (IP-Sec) tunnel establishment success message to the user equipment.
