Detailed ways

In order to solve the problems existing in the prior art, the embodiment of the present invention proposes a data service transmission method and equipment. In the technical solution of the embodiment of the present invention, the BOSS screens the transmission control users in the mobile communication network according to the set time or periodically , set the available amount of the transmission control user, and determine the number of available bytes corresponding to the data service requested by the user according to the available amount of the transmission control user, and the GGSN transmits the data service requested by the user according to the available bytes indicated by the BOSS. The technical solution of the embodiment of the present invention enables the GGSN to control the transmission of the data service requested by the user, and can control the user's consumption amount within the available amount, avoiding the user's malicious use of the packet domain data service and reducing the user's arrears risk.

Packet domain data services include content charging services and non-content charging services. Among them, due to the different tariff standards of various content charging services, in the technical solution of the embodiment of the present invention, the GGSN needs to store the charging rules and the corresponding relationship between the charging rules and the charging standards, so that the GGSN can The business attributes and charging rules are used to distinguish the type of data service requested by the user, so that the GGSN can charge the data service requested by the user according to the corresponding tariff standard.

The charging rules stored in the GGSN and the corresponding relationship between the charging rules and the charging standards are described below:

The charging rules stored in the GGSN include common charging rules and default charging rules, and each charging rule corresponds to a charging standard. Wherein, each common charging rule includes a plurality of service attributes, and when the service attribute of the data service received by the GGSN matches the service attribute of a certain common charging rule, the common charging rule is the corresponding accounting of the data service. The charging standard corresponding to the general charging rule is the charging standard of the data service. When the business attribute of the data service received by the GGSN does not match any common charging rule, the default charging rule is the charging rule corresponding to the data service, and the tariff standard corresponding to the default charging rule is the data service tariff standard. In addition, for multiple content charging services with the same tariff standard, the tariff standards corresponding to the charging rules are the same.

Common billing rules can include the following business attributes, among them, APN (Access Point Name, access point name), business ID, destination IP address and mask, destination port range, TCP/UDP ( Transmission Control Protocol/User Datagram Protocol, Transmission Control Protocol/User Datagram Protocol) protocol type is a business attribute that must be included in the general charging rules. In addition, the general charging rules can also include the seven-layer application in the seven-layer attributes URL (Uniform Resource Locator, Uniform Resource Locator) and special field values in the seven-layer application protocol:

(1) APN: The access point name corresponding to the common billing rule.

(2) Service ID: It needs to be manually configured according to the business classification, and corresponds to the common billing rules one by one.

The uplink and downlink traffic of the same type of service can be configured with different service IDs, and the service ID can be recorded in the bill to indicate the type of service. For example, the service ID can be recorded in the Record Extension field of G-CDR to distinguish the service type and facilitate the identification of the billing center. .

The business ID is a fixed-length 10-digit number, which contains four parts in sequence:

Entire network/local service identification: 1 digit, 1 indicates the entire network service, 2 indicates the local service;

Business categories: 2 digits, distinguishing whether the business belongs to WAP (Wireless Aplication Protocol, wireless application protocol), MMS, streaming media or KJAVA, etc.;

Access area: At present, there are 3 digits in China. For example, the first digit of the long-distance area code of the provincial capital will be zeroed out, and zeros will be filled on the right if there are less than three digits;

Business code: 4 digits, identifying the business that needs to further distinguish traffic under the category.

(3) Layer 3/4 attributes: including destination IP address and mask, destination port range, protocol type (TCP/UDP), and may also include source IP address and mask, source port range.

(4) Layer-7 attributes: including the URL of the layer-7 application and the special field value in the layer-7 application protocol (the x-online-host field value is required at this stage); according to the charging rules, the GGSN must be able to analyze the URL associated with a certain URL All data related to the connection, and the URL in the general billing rules should support pre, middle, post wildcards and specify multiple wildcards at the same time, such as www.isp.com/*, *.isp.com, *.mp3, www.*.com, www.isp.*, *.isp.*, etc. And it should be able to use the special field value in the seven-layer application protocol (at this stage, it is required to support the IP address of the x-online-host field) as the business attribute of the general charging rule.

Wildcards are handled according to the following regulations when matching seven-level URLs:

If "*" is used at the beginning of the URL (before "/"), it only represents a string and does not contain ".", such as "*.monternet.com" can be used to match "news.monternet.com";

"*" is used for the path part of the URL (after "/"), it can represent any character, including "/", such as "www.monternet.com/*" can be used to match anything starting with www.monternet.com/ the URL;

If "*" is used to represent a file name or file format, such as "*.mp3 or news.*", URL is usually added as a limit, such as www.monternet.com/*.mp3 can be used to match any www.monternet Files in mp3 format under the URL starting with .com;

(5) Matching priority: determine the matching order of common charging rules, which can be set manually.

When setting the matching priority for a general charging rule, the following principle should be followed: when two general charging rules are mutually inclusive, the matching priority of the subset general charging rule should be higher than that of the other general charging rule rule. For example, if the first common charging rule whose URL is www.sina.com/* contains the second common charging rule whose URL is www.sina.com/sports/*, the matching priority of the second common charging rule should be higher than the first common charging rule. This principle is also applicable to ordinary charging rules without artificially set matching priorities. For ordinary charging rules without artificially set matching priorities, the matching sequence is as shown in the flow chart in Figure 3.

After the GGSN analyzes and obtains the business attributes of the content-based charging services, according to the matching priority of the common charging rules, start matching with the common charging rules with the highest matching priority, and so on, to determine the business attributes of the content-based charging services The most matching general charging rule is the charging rule corresponding to the content charging service.

In addition, for the convenience of storage, codes can be set separately for each billing rule and each tariff standard. At this time, the way to store the corresponding relationship between the billing rule and the tariff standard can be: store the corresponding relationship between the tariff standard code and the tariff standard, The corresponding relationship between charging rule codes and charging rules is stored, and the corresponding relationship between charging rule codes and tariff standard codes is stored.

Among them, the number of general charging rules stored by the GGSN including attributes of layers 3 to 7 shall not be less than 1,000, and the number of ordinary charging rules including attributes of layers 7 shall not be less than 400; GGSN can store The number of APNs should be no less than 200.

The transmission method of the data service provided by the embodiment of the present invention includes the following parts:

1. The BOSS determines whether the user is a transmission control user according to the set time or periodically.

BOSS checks prepaid user account information and postpaid user credit information according to the set time or periodically (usually in one day). When crediting, BOSS will determine such users as transmission control users, and store the respective available amount information of such users in the BOSS domain (virtual accounts can be set to store), and mark the respective contract information of such users in HLR (Generally, the ChargingCharacteristics field can be set) to indicate that the user is a transmission control user.

Among them, the method for determining the user’s available amount includes: the balance of the prepaid user’s account is the user’s available amount; the credit of the postpaid user is converted into an amount according to a certain percentage, which is the user’s available amount, for example: the system stipulates that the postpaid user’s One credit is converted into RMB 5, if the credit of a postpaid user is 10, then the available amount of the user is 5*10=50 RMB.

2. After the GGSN receives the first data packet of the first data service requested by the user, when the user is a transmission control user, if the first data service is a content charging service, then according to the charging rules and the first data service The service attribute of the service, determining the first charging rule corresponding to the first data service, and determining the first charging standard of the first data service according to the first charging rule and the corresponding relationship between the stored charging rule and the charging standard; If the first data service is a non-content charging class service, then determine the charging standard of the first data service, as shown in Figure 2, the method further includes the following steps:

S201. When the user attaches to the packet domain network, the HLR provides the subscription information of the user to the SGSN.

S202. When the user initiates an activation request, the SGSN transmits the ChargingCharacteristics field to the GGSN through the Create PDP context Request message.

S203. After the user initiates a data service request, when the GGSN receives the first data packet of the first data service requested by the user, the GGSN checks the ChargingCharacteristics field, and when it is determined that the user is a transmission control user, execute S204; when it is determined that the user is not When transferring the control user, perform the normal data forwarding function, and do not perform subsequent steps.

S204. When the user is a transmission control user, the GGSN determines whether the first data service is a content charging service or a non-content charging service. If it is a content charging service, perform S205; if it is a non-content charging service, then Execute S206.

Usually, the GGSN can determine whether the first data service is a content charging service or a non-content charging service according to the APN information of the first data packet.

S205. When the first data service is a non-content charging service, the GGSN determines that the charging standard of the first data service is the charging standard of a non-content charging service.

S206. When the first data service is a content charging service, determine the first charging rule corresponding to the first data service according to the charging rule and the service attribute of the first data service, and determine the first charging rule corresponding to the first data service according to the first charging rule, and The stored correspondence between charging rules and charging standards determines the first charging standard for the first data service.

The embodiment of the present invention requires the GGSN to perform business analysis on different protocol layers (from layer 3 to layer 7) to the received data packets (above the GTP protocol) to obtain service attributes. For example, the GGSN should support the following levels of service analysis for data packets:

(1) Bearer layer: based on PDP (Packet Data Protocol, packet data protocol) context or APN, APN refers to the APN included in the charging rules;

(2) The third layer of IP protocol: based on source IP address, source IP address mask, destination IP address and destination IP address mask;

(3) The fourth layer of the IP protocol: based on the protocol type (such as TCP/UDP, etc.), source port number, and destination port number; in the fourth layer protocol, it should be able to support the separation of the control plane and the bearer plane (the bearer plane is controlled by the Plane dynamic allocation) protocol type, such as FTP (File Transfer Protocol, file transfer protocol) (passive mode), etc.;

(4) Application layer of IP protocol: the seventh layer, based on application URL, special field information (such as x-online-host field), etc., the support of the above URL and x-online-host field needs to consider WAP1.x and WAP2.0 agreement.

When the first data service is a content charging service and there is no artificially set matching priority in the content charging rules, the GGSN matches the charging rules and tariff standards for the first data service according to the service attributes of the first data service As described below:

A. The GGSN analyzes the third/fourth layer attributes of the data packet, and obtains information such as the destination IP address and port number of the data.

B. Match in common charging rules that include Layer 3/4 attributes;

If a general charging rule that best matches the layer 3/4 attributes of the data packet is obtained, and the general charging rule does not include the layer 7 attributes, then execute G.

If the common charging rule X that best matches the layer 3/4 attributes of the data packet is obtained, but the common charging rule X contains layer 7 attributes, then execute C.

If the Layer 3/4 attributes of the data packet cannot match any common charging rule, execute F.

C. The GGSN analyzes the seven-layer attribute of the data packet, and obtains the seven-layer URL attribute of the data packet.

D. Matching is performed in the first type of common charging rule whose third/fourth layer attribute is the same as the third/fourth layer attribute of the ordinary charging rule X and includes seven layer attributes;

If a common charging rule that best matches the seven-layer attribute of the data packet is obtained, then execute G.

If the layer-7 attribute of the data packet cannot match any common charging rule in the first type of common charging rules, then execute E.

E. If the seven-layer attribute of the data packet cannot match any one of the first-class general charging rules, then match it in the second-class general charging rule that only includes three/four-layer attributes;

If a common charging rule that best matches the layer 3/4 attributes of the data packet is obtained, execute G;

If the layer 3/4 attributes of the data packet cannot match any common charging rule in the second type of common charging rules, then execute F.

F. The default charging rule is the charging rule corresponding to the first data service, and the charging standard corresponding to the default charging rule is the charging standard of the first data service.

G. The obtained most matching general charging rule is the charging rule corresponding to the first data service, and the charging standard corresponding to the most matching general charging rule is the charging standard of the first data service.

Wherein, the following principle should be followed when matching the charging rules: when two general charging rules are mutually inclusive, the matching priority of the subset general charging rule should be higher than that of the other general charging rule.

In the embodiment of the present invention, the data services supported by the GGSN should include: HTTP (Hypertext Transfer Protocol, hypertext transfer protocol) services, WAP browsing services, MMS services, streaming media services, mail services, FTP services, etc. Therefore, GGSN should have support for HTTP, WAP1. , POP3/SMTP (Post Office Protocol-Version 3/Simple MailTransfer Protocol, the third version of the Post Office Protocol/Simple Mail Transfer Protocol) and other protocol analysis capabilities.

In addition, when the common charging rule includes an artificially set matching priority, the GGSN should match the charging rule and the charging standard for the first data service according to the matching priority of the common charging rule.

3. The GGSN initiates a request to the BOSS to determine whether transmission control needs to be performed on the user, and sends the charging standard of the first data service (abbreviated as the first charging standard) to the BOSS.

Wherein, the request initiated by the GGSN to the BOSS may be an authentication request or other forms of requests. The reason why GGSN needs to initiate a request to BOSS is that the update of user subscription information on HLR may not be timely. After GGSN determines that the user belongs to the transmission control user according to the ChargingCharacteristics field, it will request BOSS to further determine whether the user needs to be transmitted. Control can avoid transmission control for non-transmission control users and avoid affecting the quality of service for users.

4. When the user's available amount in the user's virtual account is not equal to 0, BOSS determines that it is necessary to carry out transmission control on the user, and BOSS determines the user's initial available bytes under the first tariff standard according to the first tariff standard and the user's available amount Determine the remaining available amount of the user, and indicate to the GGSN that transmission control needs to be performed on the user, and notify the GGSN of the above-mentioned initial available bytes.

When the user's available amount in the user's virtual account is equal to 0, the BOSS instructs the GGSN to interrupt the first data service.

When the user does not have a corresponding virtual account, the BOSS determines that there is no need to perform transmission control on the user, and instructs the GGSN to execute the normal data forwarding function and perform normal charging.

5. The GGSN performs transmission control on the user according to the number of available bytes indicated by the BOSS, as shown in Figure 3, including the following steps:

S301. The GGSN transmits data A whose size is the initial number of available bytes. If there is still untransmitted first data service data after data A is transmitted, the GGSN requests the second available bytes of the user under the first tariff standard from the BOSS. number;

S302. The BOSS determines the second available bytes of the user under the first tariff standard according to the remaining available amount of the user and the first tariff standard, and indicates to the GGSN, and determines the remaining available amount of the user;

S303. The GGSN transmits the data B whose size is the second number of available bytes. If there is still untransmitted first data service data after the data B is transmitted, the GGSN requests the BOSS for the third available bytes of the user under the first tariff standard. The number of sections, and so on, until all the data of the first data service is transmitted;

Wherein, in the process of S301～S303 GGSN transmits the first data service data, if the first data service data is not completely transmitted, but the user's available money is all used up, then the BOSS instructs the GGSN to interrupt the first data service; if If all the data of the first data service has been transmitted, but there are still available bytes remaining, then the process of making up the user’s available amount as described in the sixth part will be executed.

It can be seen from the above that the number of bytes available to the user under the first tariff standard is indicated by the BOSS to the GGSN multiple times, instead of using all the available amount of the user for the first data service at one time, so as to avoid one-time The user's available amount is fully used for the first data service, and when the user requests other data services, the available bytes cannot be allocated for other data services, resulting in the inability to execute other data services.

In addition, in S301-S303, when the first data service is a content charging service, the data traffic of the transmitted first data service needs to be included in the traffic corresponding to the corresponding charging rule; when the first data service If it is a non-content charging service, the traffic of the first data service is counted according to the usual method of counting traffic. During the process of transmitting the first data service data, the GGSN can generate an intermediate bill according to the first charging standard. The intermediate bills can be partial bills, and the generation conditions of some bills can be based on duration or traffic, that is, when the data transmission reaches a certain duration or traffic threshold, the bills will be closed and partial bills will be generated. The main purpose is to avoid the cycle of bill generation too long.

6. When the PDP is deactivated, the user's available amount will be replenished.

After the PDP is deactivated, if all the data of the first data service has been transmitted but the user still has the remaining available bytes under the first tariff standard, the GGSN will notify the BOSS of the remaining available bytes and request the BOSS to transfer the remaining The number of available bytes is converted into money and added back to the user's remaining available money; after receiving the request, BOSS converts the remaining available bytes into money and makes it back to the user's remaining available money.

7. During the process of transmitting the data of the first data service, the GGSN may also transmit data of other multiple data services. The transmission control method of a data service is the same.

And for other one or more data services whose tariff standard is the first tariff standard, the number of available bytes of the user under the first tariff standard can be shared with the first data service, when the first data service and other data services When the data of any data service has not been transmitted, the BOSS is requested again for the number of available bytes of the user under the first charging standard. Among them, when the above-mentioned multiple data services transmitted by the GGSN at the same time are all non-content charging services, the GGSN counts the traffic of the above-mentioned multiple data services according to the usual method of counting traffic; when the above-mentioned multiple data services transmitted by the GGSN at the same time are content For billing services, the GGSN shall count the transmitted traffic of each data service into the traffic corresponding to the corresponding billing rule, and generate intermediate bills for each data service according to the first charging standard.

For example: if the GGSN needs to transmit the first data service data and the third data service data at the same time, and the tariff standards of the first data service and the third data service are both the first tariff standard, then when the user’s available characters under the first tariff standard When the number of nodes is M, the GGSN determines that the size of the first data service that can be transmitted is m bytes, and the size of the third data service that can be transmitted is M-m bytes, and then the GGSN transmits the first data with a size of m bytes Service data, the third data service data whose size is M-m bytes is transmitted. When the data of any one of the first data service and the third data service has not been transmitted, the BOSS is requested again to the user under the first tariff standard Available bytes, and so on;

If the GGSN transmits the third data service data after transmitting the first data service data, and the charging standards of the first data service and the third data service are both the first charging standard, then when the users can use the available characters under the first charging standard The number of sections is M, and there are n bytes left in the number of available bytes after the first data service data is transmitted, then the size of the second data service data that can be transmitted by the GGSN is n bytes, when the second data service data has not been transmitted , and request the BOSS again for the number of available bytes of the user under the first tariff standard, and so on.

It can be seen that the data services with the same tariff standard share the user's available bytes under the tariff standard, which can prevent the GGSN from frequently requesting the available bytes from the BOSS and save network resources.

The technical scheme of the embodiment of the present invention is illustrated below with specific examples:

Embodiment one

Referring to Fig. 4, for the data service request whose APN is non-content billing, Embodiment 1 of the present invention adopts the following process to carry out the transmission control of the data service, wherein, during the process of executing the following process, the BOSS will regularly screen the transmission control For users, set the virtual account of such users in BOSS to store the user's available amount, and set the ChargingCharacteristics field in the respective subscription information of such users in HLR to indicate that the user is a transmission control user.

S401. When the user attaches to the packet domain network, the HLR provides the subscription information of the user to the SGSN.

S402. When the user initiates an activation request, the SGSN transmits the user's ChargingCharacteristics field to the GGSN through the Create PDP context Request message.

S403. After the user initiates a data service request, when the GGSN receives the first data packet of the first data service, it buffers the data packet first, and determines that the first data service is a non-content charging service.

S404. The GGSN checks the ChargingCharacteristics field to determine whether the user is a transmission control user, and if so, executes S405; otherwise, performs normal data forwarding function and normal charging, and does not perform subsequent steps.

S405. When the user is a transmission control user, the GGSN determines that the first charging standard of the first data service is the charging standard of a non-content charging service.

S406. The GGSN initiates an authentication request to the BOSS to determine whether transmission control needs to be performed on the user.

S407. The BOSS determines whether transmission control needs to be performed on the user according to the user's virtual account information;

When the user's available amount in the user's virtual account is not equal to 0, the BOSS determines that transmission control needs to be performed on the user, and executes S408;

When the user's available amount in the user's virtual account is equal to 0, the BOSS instructs the GGSN to suspend the service, and the GGSN suspends the service and does not perform subsequent steps.

When the user does not have a corresponding virtual account, the BOSS determines that there is no need to perform transmission control on the user, and instructs the GGSN to perform the normal data forwarding function and normal charging, and does not perform subsequent steps.

S408. The BOSS returns a response to the GGSN. The response includes: instruction information requiring transmission control for the user, information on the number of initial available bytes, and determines the remaining available amount of the user.

S409. The GGSN transmits data C whose size is the initial number of available bytes. If there is still untransmitted first data service data after the data C is transmitted, the GGSN requests the second number of available bytes from the BOSS;
