Abstract
A session association method, system, and apparatus are disclosed. The method includes: receiving an Internet Protocol Connectivity Access Network (IP-CAN) session setup message and a gateway control session message; and associating an IP-CAN session with a gateway control session according to a temporary identity (ID) in the IP-CAN session setup message and the temporary ID in the gateway control session message. Therefore, the gateway control session is associated with the IP-CAN session by using a temporary ID; and the gateway control session is associated with the IP-CAN session when no user ID exists in the emergency service, which ensures the normal progress of the emergency service.
Claims11
A session association method, comprising the steps:
- receiving an Internet Protocol Connectivity Access Network (IP-CAN) session setup message and a gateway control session message;
- and
- associating an IP-CAN session with a gateway control session according to a temporary identity (ID) in the IP-CAN session setup message and the temporary ID in the gateway control session message.
A session association system, comprising:
- a Bearer Binding and Event Reporting Function (BBERF), configured to send a gateway control session message to a Policy and Charging Rules Function (PCRF);
- a Policy and Charging Enforcement Function (PCEF), configured to send an Internet Protocol Connectivity Access Network (IP-CAN) session setup message to the PCRF;
- and
- the PCRF, configured to associate an IP-CAN session with a gateway control session according to a temporary identity (ID) in the IP-CAN session setup message and the temporary ID in the gateway control session message.
A session association apparatus, comprising:
- a receiving module, configured to receive an Internet Protocol Connectivity Access Network (IP-CAN) session setup message and a gateway control session message;
- and
- an associating module, configured to associate an IP-CAN session with a gateway control session according to a temporary identity (ID) in the IP-CAN session setup message and the temporary ID in the gateway control session message.
