Method and device for network capacity control
First Claim
1. A method for controlling a network capacity, the method comprising:
- receiving, by a Mobile Network Operator Policy and Charging Rule Function (MNO-PCRF), an instruction message for setting up an IP Connectivity Access network (IP-CAN) session for a User Equipment (UE), obtaining a UE identifier from the instruction message, and determining from the UE identifier a Mobile Virtual Network Operator (MVNO) serving the UE corresponding to the UE identifier;
forwarding, by the MNO-PCRF, the IP-CAN session setup instruction message to a Policy and Charging Rule Function (PCRF) in the MVNO (MVNO-PCRF), the MVNO serving the UE;
receiving, by the MNO-PCRF, an IP-CAN session setup acknowledgement message carrying a Policy and Charging Control (PCC) rule of the UE, sent by the MVNO-PCRF, wherein the PCC rule of the UE comprises a first granted bandwidth allocated by the MVNO-PCRF for the UE;
upon determining according to the PCC rule of the UE that the MVNO serving the UE does not exceed a granted capacity of the MVNO, replying, by the MNO-PCRF, to a network element sending the instruction message, with the P-CAN session setup acknowledgment message for the UE; and
upon determining according to the PCC rule of the UE that the MVNO serving the UE exceeds the granted capacity of the MVNO, sending, by the MNO-PCRF, to the MVNO-PCRF an alert that the granted capacity of the MVNO serving the UE is exceeded;
wherein after the alert is sent to the MVNO-PCRF that the granted capacity of the MVNO serving the UE is exceeded, the method further comprises;
starting a preset wait timer;
when a new PCC rule of the UE sent from the MVNO-PCRF is received by the MNO-PCRF before the wait timer expires, then determining again according to the new PCC rule of the UE whether the MVNO serving the UE exceeds the granted capacity of the MVNO, wherein the new PCC rule of the UE comprises a second granted bandwidth allocated by the MVNO-PCRF for the UE, the second granted bandwidth is allocated so as to avoid exceeding the granted capacity of the MVNO; and
when no new PCC rule of the UE sent by the MVNO-PCRF is received before the wait timer expires, then replying to the network element sending the instruction message, with an IP-CAN session setup failure message for the UE.

Abstract
The present invention relates to a method for network capacity control for use in controlling use by a MVNO of MNO network capacity. The method of the present invention comprises: an MNO-PCRF receives an IP-CAN session establishment instruction message and, on the basis of the user identifier therein, determines the mobile virtual network operator (MVNO) to which a UE belongs and forwards the IP-CAN session establishment instruction message to the MVNO-PCRF unit; an IP-CAN session establishment confirmation message is received from the MVNO-PCRF carrying the policy and charging control (PCC) rules of the UE, and the PCC rules of the UE are then used; when it is confirmed that the MVNO to which the UE belongs has not exceeded the authorized capacity of said MVNO, an IP-CAN session establishment confirmation.
