Method and system for session modification
First Claim
1. A method for session modification comprising:
- sending, by a network entity configured with a home policy and charging rules function (the h-PCRF network entity), a first policy and charging control (PCC) rule providing message to a packet data network gateway configured with a policy and charging enforcement function (PCEF b) according to a PCC rule request message received from an access gateway configured with an additional policy and charging enforcement function (PCEF a);
receiving, by the h-PCRF network entity, a PCC rule response message from the packet data network gateway; and
sending, by the h-PCRF network entity, a second PCC rule providing message to the access gateway according to the PCC rule response message received from the packet data network gateway.

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 first policy and charging enforcement function (PCEF) 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 a second PCEF according to a PCC rule response message received from the first PCEF. 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.

15. A system for session modification, comprising:
-
a network entity configured with a home policy and charging rules function (the h-PCRF network entity), wherein the h-PCRF network entity is configured to be communicatively connected to an access gateway and a packet data network gateway, the access gateway being configured with a policy and charging enforcement function (PCEF a) and the packet data network gateway being configured with an additional policy and charging enforcement function (PCEF b);
wherein;the h-PCRF network entity is further configured to send a first policy and charging control (PCC) rule providing message to the packet data network gateway according to a PCC rule request message received from the access gateway, to receive a PCC rule response message from the packet data network gateway; and
to send a second PCC rule providing message to the access gateway according to the PCC rule response message received from the packet data network gateway. - View Dependent Claims (16, 17)
