Abstract
A method and system for session modification are provided. The method includes these steps: A home policy and charging rules function (h-PCRF) sends a policy and charging control (PCC) rule providing message to a policy and charging enforcement function (PCEF) b according to a received PCC rule request message, an application layer service message, or an h-PCRF self-trigger event; and the h-PCRF sends a PCC rule providing message to the PCEF a according to a PCC rule response message received from the PCEF b. With this present disclosure, session modification may be implemented when two or more PCEFs are included in the PCC architecture of a system architecture evolution (SAE) system.
Claims19
A method for session modification, comprising:
- receiving, by a home policy and charging rules function (h-PCRF), a policy and charging control (PCC) rule request message;
- sending, by the h-PCRF, a first PCC rule providing message to a second policy and charging enforcement function (PCEF b) according to the received PCC rule request message;
- receiving, by the h-PCRF, a PCC rule response message from the PCEF b;
- and
- sending, by the h-PCRF, a second PCC rule providing message to a first policy and charging enforcement function (PCEF a) according to the PCC rule response message received from the PCEF b.
A method for transferring information, comprising:
- receiving, by a home policy and charging rules function (h-PCRF), a policy and charging control (PCC) rule request message from a first policy and charging enforcement function (PCEF a);
- obtaining, by the h-PCRF, information of a trigger event that occurs on the PCEF a and information of affected PCC rules from the received PCC rule request message;
- and
- sending, by the h-PCRF, a PCC rule providing message to a second policy and charging enforcement function (PCEF b), where the PCC rule providing message comprises the information of the trigger event that occurs on the PCEF a.
A system for session modification, comprising:
- a home policy and charging rules function (h-PCRF), configured to receive a policy and charging control (PCC) rule request message;
- send a first PCC rule providing message to a second policy and charging enforcement function (PCEF b) according to the received PCC rule request message;
- receive a PCC rule response message from the PCEF b;
- and
- send a second PCC rule providing message to a first policy and charging enforcement function (PCEF a) according to the PCC rule response message received from the PCEF b.
A system for session modification, comprising:
- a home policy and charging rules function (h-PCRF), configured to receive a policy and charging control (PCC) rule request message from a first policy and charging enforcement function, PCEF a;
- obtain information of a trigger event that occurs on the PCEF a and information of affected PCC rules from the received PCC rule request message;
- and
- send a PCC rule providing message to a second policy and charging enforcement function (PCEF b), where the PCC rule providing message comprises the information of the trigger event that occurs on the PCEF a.
