Detailed Description
In order that those skilled in the art will better understand the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.
In charging for network users, some network providers may set a dedicated charging server (Radius) through which to charge for network users, and also charge for local network access devices in order to prevent charging information loss due to the failure of the charging server. However, for economic reasons, it is also possible to charge only the local network access device without setting a dedicated charging server, integrate the charging module on the network access device, and use the charging module to charge the network user. The working flow of the method of the present invention is described in detail below by way of example of charging via a dedicated charging server, in which case no mention is made of charging of network users on a local access device.
Referring to fig. 2, fig. 2 is a flowchart illustrating the steps of charging through a charging server in the embodiment of the charging method for network access of the present invention:
firstly, network resources which a user may access are divided into different charging categories by address on a local network access device (NAS) in step 20;
then, go to step 21, configure the rate of different charging categories on the charging server; into
In step 22, the user accesses the network through the local NAS, and starts to request charging at this time;
in step 23, the local NAS sends a charging start request message to the charging server, where the message is the same as the charging start request message in the prior art;
proceeding to step 24, the local NAS receives a charging start request response message sent by the charging server after receiving the charging start request message;
then, in step 25, the local NAS sends a charging update request packet to the charging server, and starts timing, where the charging update request packet not only includes traditional charging information, such as the total accumulated traffic or the total accumulated duration of the user accessing the internet, but also includes charging information counted according to different charging categories of destination addresses, such as the total accumulated traffic or the duration of the user accessing a certain category of network resources, and then charging starts;
proceeding to step 26, the NAS respectively accumulates the traffic or the duration of the user accessing the network resources of different charging categories according to the divided different charging categories, which includes: accessing charging information (flow or time length) of free network resources and charging information (flow or time length) of non-free network resources, obtaining non-free total charging flow or total time length according to the charging information, and adding the accumulated flow or time length of the network resources accessed by the user in different charging categories and the obtained non-free total charging flow or total time length into corresponding fields of the charging updating request message;
in order to prevent the influence of the interruption of the user connection on the charging caused by abnormal conditions, a proper time interval is usually set according to the actual needs of the system, after the user starts charging, a charging updating message is retransmitted every other time interval, the charging updating message contains the accumulated charging information of the user accessing network resources of different charging categories, and then the flow or the time length of the user accessing the network resources of different charging categories is continuously accumulated according to the divided different charging categories;
therefore, go to step 27 to determine if the user has been offline and disconnected;
if the user is not offline within the preset time interval, returning to the step 25 after the timing reaches the set time interval, and the local NAS sending a charging updating request message to the charging server and restarting timing;
otherwise, step 28 is executed to send a charging end request message to the charging server by the NAS, and similarly, the charging end request message not only includes traditional charging information, such as the total accumulated traffic or the total accumulated duration of the user accessing the internet, but also includes charging information counted according to charging categories with different destination addresses, such as the total accumulated traffic or the duration of the user accessing a network resource of a certain category.
Then, proceeding to step 29, the user is charged separately at the charging server according to the configured rates of the different charging categories.
In practical applications, it is also generally required to charge the network access user on the NAS at the same time, or to charge the network access user only on the local NAS without providing a dedicated charging server. The implementation procedure is similar to the above example, and is described in detail below with reference to fig. 3:
firstly, network resources which a user may access are divided into different charging categories according to addresses on a local network access device (NAS) in step 30;
then, proceeding to step 31, configuring different charging rates of different charging categories on the charging module of the NAS;
proceeding to step 32, the user accesses the network through the local NAS, and at this time, starts to request charging;
in step 33, the local NAS sends a charging start request message to the charging module;
proceeding to step 34, the local NAS receives a charging start request response message sent by the charging module after receiving the charging start request message;
then, in step 35, the local NAS sends a charging update request message to the charging module, and starts timing, where the charging update request message not only contains traditional charging information, such as the total accumulated traffic or the total accumulated duration of the user accessing the internet, but also includes charging information counted according to different charging categories of destination addresses, such as the total accumulated traffic or the duration of the user accessing a certain category of network resources, and then charging starts;
proceeding to step 36, the NAS respectively accumulates the traffic or the duration of the user accessing the network resources of different charging categories according to the divided different charging categories, which includes: accessing charging information (flow or time length) of free network resources and charging information (flow or time length) of non-free network resources, obtaining non-free total charging flow or total time length according to the charging information, and adding the accumulated flow or time length of the network resources accessed by the user in different charging categories and the obtained non-free total charging flow or total time length into corresponding fields of the charging updating request message;
in order to prevent the influence of the interruption of the user connection on the charging caused by abnormal conditions, a proper time interval is usually set according to the actual needs of the system, after the user starts charging, a charging updating message is retransmitted every other time interval, the charging updating message contains the accumulated charging information of the user accessing network resources of different charging categories, and then the flow or the time length of the user accessing the network resources of different charging categories is continuously accumulated according to the divided different charging categories;
therefore, go to step 37 to determine whether the user has disconnected due to offline;
if the user is not offline within the preset time interval, returning to the step 35 after the timing reaches the set time interval, and the local NAS sends a charging update request message to the charging module and restarts timing;
otherwise, step 38 is proceeded, the NAS sends a charging end request message to the charging module, and similarly, the charging end request message not only contains the traditional charging information, for example, the total accumulated traffic or the total accumulated duration of the user accessing the internet, but also contains the charging information counted according to the charging categories with different destination addresses, for example, the total accumulated traffic or the duration of the user accessing the network resource of a certain category.
Then, proceeding to step 39, the user is charged separately on the charging module according to the configured rates of different charging categories.
To further illustrate the statistics and transmission process of the charging information in the charging method for network access of the present invention, fig. 4 describes the message interaction process between the NAS and the charging server:
1. after the user is online, the NAS sends a charging start request message to a charging server to request for charging the user, and the charging start request message is the same as the charging start request message in the prior art;
2. after receiving the charging start request message sent by the NAS, the charging server responds to a charging start request response message to prepare for starting charging;
3, after receiving the response message of the charging start request, the NAS sends a charging update request message to the charging server, where the charging update request message not only contains traditional charging information, such as the total accumulated traffic or the total accumulated duration of the user accessing the internet, but also includes charging information counted according to different charging categories of destination addresses, such as the total accumulated traffic or the duration of the user accessing a certain category of network resources, and at this time, the charging server can charge the user according to the charging information in the message and according to configured rates of different charging categories;
meanwhile, the NAS starts to respectively accumulate the flow or the duration of the network resources of the user accessing different charging types according to the divided different charging types, and adds the charging information into the next charging updating request message;
the NAS sends a new charging updating request message, and the interval for sending the charging updating request message can be set according to the actual charging requirement;
5. the user is off line and disconnected, at this time, the charging is finished, the NAS sends a charging finishing request message, which, like the charging updating request message, not only contains the traditional charging information, such as the total accumulated flow or the total accumulated duration of the user accessing the internet, but also includes the charging information counted according to different charging types of destination addresses, such as the total accumulated flow or the duration of the user accessing a certain type of network resources, and the charging server can respectively charge the user according to the configured rates of different charging types according to the charging information in the message.
In the above embodiment, the accumulated charging information of different charging categories is placed in the same message by extending a Radius (charging server) protocol and is transmitted to the charging server for charging, and the original attributes such as the total accumulated flow and the total accumulated duration of the internet are still transmitted, so that the method is compatible with the traditional charging mode.
The extension of the attributes in the accounting (update/end) request message is described in detail below.
In the charging (update/end) request message, a VSA attribute is added, the attribute type is 40, and the length of the character string is 253 at most, and each character string represents charging information of a charging category. In the charging (update/end) request message, there may be a plurality of such character strings, each corresponding to a different charging category.
The structure of the character string is as follows:
n ═ class number >;
IP ═ number of incoming messages >;
OP ═ number of output messages >;
IF ═ input flow >;
OF ═ output flow >;
u ═ input/output flow rate unit >
"N", "IP", "OP", "IF", "OF", "U", or "═ belong to special characters for distinguishing between domains; "separate, no order requirement, string end none"; ".
Wherein,
<category numbering>The class number of the destination IP address is expressed, and the value range is [0, 2 ]8-1]，
<Number of input messages>、<Number of outgoing messages>、<Input flow rate>、<Output flow>The accumulated message quantity and flow of the category since the Internet is accessed are represented, and the value range is [0, 2 ]32-1]。
The < input and output flow unit > is composed of two letters, the former letter represents the input flow unit, and the latter letter represents the output flow unit, so as to prevent the situation that the input and output flows are greatly different.
"B" indicates the unit of traffic as bytes, "K" indicates the unit of traffic as 1024 bytes, and "M" indicates the unit of traffic as 1048576 bytes. If "U ═ KB" indicates that the input traffic unit is 1024 bytes, the output traffic unit is bytes.
In order to ensure the accuracy of the traffic information, the traffic unit takes bytes (B).
For example:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Type＝40 | Length＝50 | String＝″N＝2；IP＝12345678；OP＝
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
123456；IF＝123456；OF＝1234；U＝BB″|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
the attribute 40 can only appear in the charging update/end request message, and can appear for many times to correspond to the situation of multiple non-free IP address categories.
Referring again to fig. 5, fig. 5 is a schematic diagram of a charging mode of the charging method for network access of the present invention:
the method comprises the steps of dividing the network resources accessed by users into four different charging categories according to the addresses of the network resources accessed by the users, enabling the domestic education network to be free resources, enabling the foreign education network, the science and technology network and the telecommunication network to respectively adopt different charging rates, enabling the flow or the duration accessed by the users to be respectively counted in the four categories when the users access the network resources, generating charging information of the different categories and total accumulated flow and/or total accumulated duration information, transmitting the charging information to a charging server, enabling the charging server to respectively charge according to the charging rate corresponding to each category, meanwhile enabling the charging to be carried out according to the total accumulated flow and/or total accumulated duration information of the internet, and being compatible with the existing charging mode.
Although the present invention has been described by way of example, those skilled in the art will appreciate that there are numerous variations and permutations of the present invention without departing from the spirit of the invention, e.g., billing by classifying billing categories according to different ISPs (Internet service providers) or billing by classifying billing categories according to different domain names, and it is intended that the appended claims encompass such variations and permutations without departing from the spirit of the invention.
