Method and system for notifying access network location information

A method for notifying access network location information, comprising:

• sending, by a local General Packet Radio Service Tunneling Protocol (GTP) peer, a circuit ID to a correspondent GTP peer by carrying the circuit ID in a Create Session Request message, a Modify Bearer Request message or a Delete Session Request message;
• and
• acquiring, by the correspondent GTP peer, the circuit ID carried in the Create Session Request message, the Modify Bearer Request message or the Delete Session Request message and sending, by the correspondent GTP peer, the acquired circuit ID to a policy system and/or a charging system;
• and
• making or configuring, by the policy system, corresponding policy rules according to the acquired circuit ID, and charging, by the charging system, according to the acquired circuit ID,
• wherein the circuit ID comprises at least one of the following:
• a Router interface number, a Switching Hub port number, a Remote Access Server port number, a Frame Relay Data Link connection identifier, an Asynchronous Transfer Mode (ATM) virtual circuit number, and a Cable Data virtual circuit number.

A system for notifying access network location information, comprising a Mobile Access Gateway (MAG) and a Local Mobility Anchor (LMA) in a Proxy Mobile IPv6 (PMIPv6) architecture, or comprising a local General Packet Radio Service Tunneling Protocol (GTP) peer and an correspondent GTP peer in a GTP architecture, wherein

• the MAG is configured to send a circuit identifier (ID) to the LMA by carrying the circuit ID in a proxy binding update message;
• and
• the local GTP peer is configured to send a circuit ID to the correspondent GTP peer by carrying the circuit ID in a Create Session Request message, a Modify Bearer Request message or a Delete Session Request message,
• wherein the circuit ID comprises at least one of the following:
• a Router interface number, a Switching Hub port number, a Remote Access Server port number, a Frame Relay Data Link connection identifier, an Asynchronous Transfer Mode (ATM) virtual circuit number, and a Cable Data virtual circuit number.
