Abstract
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.

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);
- said PCRF entity sending the location information of said UE to a broadband policy control function (BPCF) entity.
A system for information transmission, comprising an evolved packet data gateway (ePDG), a policy and charging rules function (PCRF) entity and a broadband policy control function (BPCF) entity;
- wherein, said ePDG is set to:
- notify the PCRF of location information of the UE;
- said PCRF entity is set to:
- send said location information of the UE to said BPCF entity.
A policy and charging rules function (PCRF) entity, comprising:
- an information receiving unit, used to receive location information of a user equipment (UE) sent by an evolved packet data gateway (ePDG);
- an information sending unit, used to send the location information received by the information receiving unit to a broadband policy control function (BPCF) entity.
