Description

Method and related device for real-time monitoring of PS domain traffic

Technical field

This document relates to, but is not limited to, the field of communication technologies, and in particular, to a method and a related device for real-time monitoring of a packet in a PS (Packet Switching Domain).

Background technique

The CS Domain (Circuit Switching Domain) calls cannot be called, and the tariff per minute is fixed. Therefore, the user knows how much he or she has consumed, and the money bag is controllable. When entering the PS domain, the data service can be concurrent with multiple services, and the use of traffic is currently not intuitive, so users cannot know exactly how much traffic they use. Therefore, there will be sky-high CDRs and complaints about tariffs.

For example, the traffic of a carrier's mobile phone is 500M per month. At the end of the month, you can check the traffic call or check the remaining 30M of the remaining traffic on the website. You can download a 28M application. After a while, you will receive a text message saying that the traffic has been sent. Exceeding the package, the extra part is charged according to what the fee is charged. The reason is that for OCS (Online Charging System), the billing is real-time, but the bills generated by OCS are not real-time, and need to wait until the timing is triggered or the user deactivates to generate the bill. After the bill is generated, the front-end service or SMS system can query how much traffic the user has used. This leads to a delay in billing prompts and misleading consumers.

At present, there are some solutions: the mobile phone comes with or installs an application APP provided by a third party for traffic monitoring, and can set traffic reminders and use thresholds, but the drawbacks are obvious:

First: the flow control is based on the mobile phone to send and receive data, and the fragmentation and retransmission in the network process are not perceived, and the traffic statistics are not accurate;

Second: these software operators do not recognize, can not be used as the basis for billing and complaints, billing problems, and still subject to operator billing, for processing;

Third: For free services, only OCS knows that business operations are classified by mobile phones, such as mobile phone Taobao traffic in some provinces.

Therefore, the current flow control applications in mobile phones, errors and loopholes are very large.

When receiving the CCR-I message sent by the user through the charging gateway for the network authentication, the OCS extracts the data service flow control parameter from the CCR-I message, where the data service flow control parameter is in the Diameter protocol. The AVP structure is inserted into the circuit domain information under the service information carried in the CCR-I message. The Flow Monitor-Value property is used to carry the flow threshold in the flow control parameters.

Step 102: The OCS monitors the process of using the data service traffic by the user. When the data traffic that has been used by the user reaches the traffic threshold, the monitoring result is prompted by the charging gateway. To the user.

In step 102, when it is monitored that the data service traffic that the user has used reaches the traffic threshold, the monitoring result is displayed to the user through the charging gateway, including:

If the preset traffic quota is greater than the traffic threshold minus the difference between the data traffic used by the user, And the difference between the traffic threshold and the data traffic that has been used by the user is used as the current traffic quota, if the preset traffic quota is less than or equal to the traffic threshold minus the data traffic used by the user. If it is poor, it will be delivered according to the preset traffic quota.

Optionally, when the data traffic that has been used by the user is monitored, the data service is applied to the user through the charging gateway, and the data service of the current application for the traffic quota is terminated by the charging gateway. Optionally, when the data service of the current application for the traffic quota is terminated, the user may also perform the redirection, for example, jumping to a set webpage to prompt the user to terminate the service.

Embodiment 2

In step S612, since the online charging system has the same rating for the service each time, it is determined whether the difference between the traffic threshold and the data service traffic that the currently accumulated user has used is less than the quota of the rating (for example: each time 5M), if the traffic threshold minus the current accumulated data traffic of the user is less than the quota of the quota, the traffic threshold is subtracted from the current accumulated data traffic of the user. The traffic quota is delivered according to the traffic quota set by the online charging system, if the traffic threshold is less than or equal to the quota of the data traffic that has been used by the user.

In step S618, it is also possible that the data service traffic that the currently accumulated user has used is greater than the new traffic monitoring threshold. If it occurs, the processing is performed according to step S624.
