Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 1 is a flowchart of a method for determining interface parameters according to an embodiment of the present invention, and as shown in fig. 1, the method for determining interface parameters includes:
Here, the execution subject of the method for determining the interface parameter may be a device for determining the interface parameter, and the device for determining the interface parameter may be disposed inside the BOSS/OCS, or may be configured separately; the maximum service rate for guaranteeing the user perception defines the maximum service rate for guaranteeing the user perception, and the maximum service rate for guaranteeing the user perception in the 4G network can adopt the average service rate of the 4G network; the interface signaling interaction average time delay defines a Gy interface CCR/CCA signaling interaction average time delay, and specifically may be an average time delay of a quota obtained from a time when a PGW initiates a CCR signaling application quota to a time when a CCA response issued by a BOSS/OCS is received.
Here, when the user uses the service and the remaining quota of the user reaches the traffic threshold, the PGW triggers the CCR signaling to apply for a new quota, and allows the user to consume the quota in the traffic threshold to continue the service; or when the user quota is not used up but the quota valid time is expired, the PGW also triggers CCR signaling to update the quota.
However, in the prior art, default values or empirical values are adopted for setting quotas, traffic thresholds, and quota valid times, and these default values or empirical values are often not adapted to factors such as changes in a traffic model and changes in user requirements, which easily causes a PGW to frequently apply for quotas from an OCS, and further generates a large amount of Gy interface interactive signaling, resulting in an excessively high Gy interface signaling load and an excessively high processing load of the OCS.
In the embodiment of the invention, the flow threshold is determined according to the acquired maximum service rate which guarantees the perception of the user and the average time delay of interface signaling interaction instead of adopting the default value or the empirical value for setting the flow threshold.
On the basis of the above embodiment, a feasible implementation manner for determining the traffic threshold according to the maximum service rate and the average interface signaling interaction delay, which guarantee user perception, is as follows:
and calculating the product of the maximum service rate for ensuring the user perception and the average interface signaling interaction time delay, and determining the calculated product value as a flow threshold value.

calculating the difference value between the maximum fragment quota and the flow threshold value under the condition of guaranteeing the real-time charging precision;
then calculating the ratio of the difference value to the minimum service rate perceived by the guaranteed user;
and determining the calculated ratio as a reference value of the quota valid time.
Optionally, the VT is determined by using the following formula (2) according to the traffic threshold, the maximum fragment quota for guaranteeing the real-time charging accuracy, and the minimum service rate for guaranteeing the user perception:
VT＝(A-VQT)/C (2)；
wherein the VT is a quota valid time; the A is the maximum fragment quota under the condition of guaranteeing the real-time charging precision; c is the minimum service rate for guaranteeing the user perception; in a scenario of 2G, 3G, and 4G hybrid networking, the C may adopt an average traffic rate of the 2G network.
