Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one of the present invention:

Fig. 1 is a flowchart of an embodiment of a method for authorizing terminal data traffic in the present invention. As shown in Fig. 1, the method may include:

S101. The OCS receives a traffic application request sent by the GGSN, and the request carries a user identifier and a traffic rate used by the user;

Wherein, the traffic rate used by the user indicates the amount of traffic used by the user per unit time. The user identifier can be a mobile station international ISDN number (Mobile Subscriber International ISDN number, MSISDN), or other user identifiers.

It should be noted that the GGSN obtains the amount of traffic used by the user and the duration of the traffic used, and calculates the rate of traffic used by the user. The calculation method of the traffic rate used by the user is as follows: set the timer, configure the timing time, start the timer when the user starts to use the traffic, and obtain the traffic volume used by the user when the traffic usage time is equal to the timing time.

The GGSN sends an application traffic request to the OCS through the Diameter Credit Control protocol (Diameter Credit Control, DCC). Before sending, the GGSN encapsulates the user traffic rate into the extension field of the application traffic request. Specifically, it can be encapsulated into the AVP (Attribute-Value-Pair) parameter field in the DCC protocol, or it can be encapsulated into other parameter fields. This embodiment of the present invention is not limited thereto.

S102. Determine the authorized traffic size of the user, send the authorized traffic size to the GGSN, and trigger the GGSN to monitor the traffic used by the user.

Before the OCS receives the application traffic request sent by the GGSN, the OCS also needs to configure the user's authorized traffic table;

OCS itself saves information such as the user brand, package, remaining traffic included in the package, balance range, etc., and this information corresponds to the user ID of the user one by one. Therefore, after receiving the user ID of the user, the OCS can obtain information such as the user's brand and package of the user.

The characteristic information of the user includes the user brand, the package, the remaining traffic included in the package, and the balance range. User brands take mobile operators as an example, there are three brands: GSM, Shenzhouxing and M-Zone; packages are the charging rules and preferential tariff packages stipulated by the operators.

Specifically, the OCS queries the user's authorized traffic table, determines the authorized traffic volume of the user, and calculates the balance occupation corresponding to the authorized traffic volume according to the traffic tariff corresponding to the user brand. After calculating the size of the balance occupation, calculate the estimated time for receiving the next application according to the traffic rate used by the user.

Through the method provided by the embodiment of the present invention, the OCS obtains the characteristic information of the user by receiving the user identification sent by the GGSN and the traffic rate used by the user, and queries the user authorized traffic table to determine the authorized traffic of the user and send it. It solves the problem that end users cannot perform data services when the application frequency is high due to OCS authorized fixed traffic, and improves user experience.

Embodiment two of the present invention:

As shown in Figure 2, in this embodiment, the flow of OCS authorized traffic is as follows:

S201. The OCS configures a user authorization flow table;

Before receiving the traffic application, the OCS configures the user authorization flow table. The authorized flow table includes information such as user characteristic information, user usage rate, and user authorized flow size. Wherein, the characteristic information of the user includes the user brand, package, and balance. The user brand takes the mobile operator as an example, there are three brands of GSM, Shenzhouxing and M-Zone; the package is the charging rule stipulated by the operator. The traffic rate used by the user indicates the amount of traffic used by the user per unit time.

It should be noted that, in order to ensure the processing capability of the OCS, the session interaction needs to meet a certain time interval. If the time interval is shorter than this time interval, the OCS may not be able to respond to the application traffic request. In this embodiment, it can be set as 20 minutes or more, and the embodiment of the present invention has no limitation on the specific time interval. After the time interval is determined, the authorized traffic size can be calculated according to the usage traffic rate and the time interval. Authorized traffic = usage traffic rate * time interval, which means the authorized traffic size for users. FIG. 3 shows a set of correspondence tables in the embodiment of the present invention. In the embodiment of the present invention, there is no limit to the parameter values configured in the table, and other similar parameters belong to the protection scope of the embodiment of the present invention.

S202. The SGSN sends a data service request to the GGSN;

The user equipment UE starts a data service, and the SGSN sends a data service request to the GGSN, requesting the GGSN to process the data service.

S203. The GGSN sends an application flow request message to the OCS;

After receiving the request from the SGSN, the GGSN sends an application traffic message request to the OCS, which can be communicated through the DCC. The message request can be a DCC request message (Credit Control Request, CCR) in the DCC protocol. The CCR message carries the size of the reserved amount to apply for. The application reserved amount is a default value configured by the GGSN, for example, it may be 1MB, 2MB or other values, which is not limited in this embodiment of the present invention.

S204. The OCS determines the size of the user's authorized traffic;

Since it is the first time that the GGSN sends a flow request, after the OCS obtains the user characteristic information, it determines that the default authorized application volume is the authorized flow to be sent, and there is no need to query the user authorized flow table. The default authorized application amount can be the reserved application amount sent by GGSN, or the default reserved application amount configured by itself, which can be 1M, 2M or others. The embodiment of the present invention does not limit the specific size.

S205. The OCS returns the authorized traffic size to the GGSN;

The OCS sends a DCC request response message (Credit Control Answer, CCA) to the GGSN, and the message carries the authorized traffic size.

S206. The GGSN monitors the traffic used by the user and calculates the traffic rate used by the user;

GGSN monitors the traffic actually used by the user and calculates the traffic rate used by the user. The method is as follows:

Set the timer and configure the timing time. The timing time is less than or equal to the time when the new traffic application is submitted. When the user starts to use the traffic, activate the timer and start counting. When the timing is reached, the traffic size used by the user is obtained, and the traffic rate used by the user is calculated. The traffic rate used by the user = the size of the traffic used by the user / the timing time.

S207, the GGSN applies for new traffic to the OCS;

After the first application flow is used up, the GGSN applies for a new flow to the OCS, and the request message and details can be CCR. Wherein, the CCR carries the usage traffic rate and the subscriber identifier, and the subscriber identifier may be a Mobile Subscriber International ISDN number (MSISDN), or other subscriber identifiers. GGSN encapsulates the rate of traffic used by the user into the extension field of the application traffic request. Specifically, it can be encapsulated into the AVP (Attribute-Value-Pair) parameter field in the DCC protocol, or it can be encapsulated into other parameter fields. Embodiments of the present invention There is no limit to this. S208. The OCS determines a new authorized flow size;

After OCS receives a new application, it deducts the used traffic. Since the OCS stores the user's feature information such as user brand, package, and balance, and the information is in one-to-one correspondence with the user ID, after receiving the user ID sent by the GGSN, the OCS obtains the user's feature information corresponding to the user ID.

After the OCS obtains the user's characteristic information, it queries the user's authorized flow table according to the user's characteristic information and the user's traffic rate to determine the user's new authorized traffic size.

OCS calculates the size of the balance occupation based on the received user package information. For example, if the user package is 1 cent/KB, and the new authorized traffic is 200KB, then the balance occupied size is 200*1 cent, which is 2 yuan.

The OCS calculates the expected time for receiving the next application based on the received user rate. For example, if the user rate is 100KB/min, and the new authorized traffic is 2000KB, then the expected time to receive the next application is 2000/100min, which is 20min.

S209. The OCS sends a new authorized traffic size to the GGSN;

After the OCS determines the new authorized traffic size, it sends the new authorized traffic size to the GGSN, triggering the GGSN to monitor the next round of user traffic.

S210. The user closes the data service and initiates an offline application;

S211. The OCS writes a bill according to the actual traffic usage and deducts fees, and ends the session.

Through the method provided by the embodiment of the present invention, the OCS obtains the characteristic information of the user by receiving the user identification sent by the GGSN and the traffic rate used by the user, and queries the user authorized traffic table to determine the authorized traffic of the user and send it. It solves the problem that end users cannot perform data services when the application frequency is high due to OCS authorized fixed traffic, and improves user experience.
