Description

Overload control method and device for charging request message

Technical field

The present application relates to, but is not limited to, the field of communications, and in particular, to an overload control method and apparatus for a charging request message.

Background technique

At present, the Diameter overload control mode of the existing offline charging interface Rf of 3GPP uses the "DIAMETER_TOO_BUSY" error response code to indicate that the charging interface has reached the overload state. Specifically, if the Charging Trigger Function (CTF) does not receive the Accounting Request Answer (ACA) in time, it will usually receive the Charging Data Function (CDF). "DIAMETER_TOO_BUSY" error response code. At this time, every other operator can configure the waiting time, the CTF will resend the cached charging request message (ACR, Accounting Request) to the CDF. When the number of repeated transmissions reaches the maximum number of repetitions configured by the operator, When the ACA response message is still not received, the CTF will perform the connection failure processing.

Optionally, if the cached ACR is not a new charging request message, but a subsequent ACR (for example, ACR[Interim] and/or ACR[Stop]) that was successfully sent to the ACR of the broken CDF, the CTF will Each time a certain operator can configure the waiting time, the cached ACR is sent to the broken CDF. Since the charging information cannot be lost, such retransmission process will be repeated indefinitely until the link is restored. .

With the Diameter overload control method described above, there is a problem that an overload has occurred on the offline charging interface Rf, but the CTF still retransmits the ACR on the interface, which will inevitably cause an overload situation to be more serious. That is to say, since the overload control method in the related art starts the control after the occurrence of the overload phenomenon, the control process is relatively lagging, and in the overload control process, the overload condition may become more serious. In other words, with the related art overload control method, the system may collapse due to the inability to detect and prevent the overload in time.

Optionally, in this embodiment, the overload control method of the foregoing charging request message may be, but is not limited to, applied to a Diameter overload control process on a charging interface, which is different from the related art in receiving a Diameter for indicating that a Diameter has been received. After the error response code of the overloaded "DIAMETER_TOO_BUSY" is started, the control overload is started. The overload control method of the charging request message provided in this embodiment passes the charging trigger function unit (CTF, Charging Trigger Function) located in the network element. Real-time access to the overload control reduction percentage information and overload control identifier carried in the ACA ACA to pre-determine whether the charging interface will be overloaded, so that in the normal communication process, the overload can be discovered in time, and the charging interface is overloaded in advance. Control, thereby avoiding increased system load and increased overload due to overload hysteresis.

Optionally, in this embodiment, the foregoing ACR may include, but is not limited to, identifier information that supports Diameter Overload Indication Conveyance (DOIC). The identifier information may be a sub-AVP of a Bool type in the AVP of the combined type of the OC-OLR, such as a Charging DOIC Indicator, or a redefinition of the value of the existing OC-Feature-Vector AVP. For example, the OLR_Charging_ALGO (0x0000000000000010) used to represent the overload report charging algorithm is an algorithm identification value used for charging in the OC-Feature-Vector AVP. (This OC-Feature-Vector AVP is used to represent the DOIC attributes supported by the DOIC node. Currently there is a value of OLR_DEFAULT_ALGO(0x0000000000000001) that represents the default overload control algorithm)

Optionally, in this embodiment, the overload control reduction percentage information and the overload control identifier are combined into an AVP overload report (such as OC-OLR) and carried in the response message ACA. The above overload control reduction percentage information may be, but is not limited to, determined by the first charging data function unit according to a current load situation (eg, CPU usage).

The second charging data function unit and the first charging data function unit that receives the ACR may be, but are not limited to, different charging data function units.

It should be noted that, as an important operational data for the operator, the user charging message cannot be discarded at will, and therefore the Loss Algorithm overload control method cannot be used to cancel the overload of the charging interface. In order to avoid missing the charging request, the overload control operation provided in this embodiment may include, but is not limited to, at least one of: buffering the current ACR into the ACR queue in the local storage, and transmitting the current ACR to the second charging data. Functional unit. That is, the ACR is forwarded to the second charging data function unit for processing, or is temporarily buffered, and then re-sent to the first charging data function unit after the overload is released, thereby avoiding missing ACR, such as ACR[Start ] and its subsequent ACR [Interim] and ACR [Stop], in order to achieve the effect of improving the accuracy of billing. Optionally, the overload control identifier may be, but is not limited to, a new overload control method used to indicate a Charging Trigger Function (CTF), and the Loss default overload control method is used to process the Loss Algorithm.

Alternatively, in the present embodiment, in the process of performing the overload control operation proportionally, the current ACR may be controlled according to the overload control reduction percentage information. For example, the higher the overload control reduction percentage indicated by the overload control reduction percentage information, the more the ACR is filtered, so as to alleviate the processing load of the first charging data function unit, so as to realize the timely avoidance of the first charging data function. The unit has an overload problem.

Specifically, the following example is used to illustrate that the flow of the overload control method of the charging request message shown in FIG. 2 may include steps S202 to S208: S202, the CTF 22 sends the current ACR to the first CDF 24; S204, the CTF 22 acquires and is currently Overload control carried in ACA corresponding to ACR And reducing the percentage information and the overload control identifier; S206, the CTF 22 determines, according to the overload control reduction percentage information in the ACA, whether the charging request message in the first charging data function unit is overloaded; S208, if the charging is performed in the first charging data function unit If the request message is overloaded, the overload control operation is performed on the current ACR according to the overload control mode indicated by the overload control flag.

Through the embodiment provided by the present application, the overload control reduction percentage information and the overload control identifier carried in the current ACR of the current ACR are obtained in real time, and the charging request message in the first charging data function unit is pre-determined according to the overload control reduction percentage information. Whether an overload occurs. If it is determined that the charging request message in the first charging data function unit has been overloaded, the overload control operation is performed on the current ACR according to the overload control mode indicated by the overload control flag, wherein the overload control operation is used at least for Instructing not to send the current ACR to the first charging data function unit, that is, to reduce the processing amount of the first charging data function unit by reducing the processing amount of the first charging data function unit, thereby reducing the first meter The processing load of the data function unit; optionally, the overload control method indicated by the overload control identifier carried in the ACA is used in the normal communication process, and the charging interface is overloaded in advance, thereby avoiding overload The system load caused by the lag increases, and the overload increases.

As an optional solution, the performing an overload control operation on the current ACR according to the overload control mode indicated by the overload control identifier includes:

S1, randomly acquiring a target value within a predetermined sequence, wherein the predetermined sequence is arranged in ascending order;

S2, obtaining a percentage of the target value obtained, wherein the obtaining percentage is a percentage of the serial number of the target value in the predetermined sequence and the total amount of the predetermined sequence;

S3, comparing the percentage of the acquisition percentage and the overload control reduction percentage indicated by the overload control reduction percentage information;

S4, if the acquisition percentage is greater than the overload control reduction percentage, the current ACR is sent to the first charging data function unit;

S5. If the acquisition percentage is less than or equal to the overload control reduction percentage, the overload control operation is performed on the current ACR.

Optionally, in this embodiment, the foregoing overload control operation may include, but is not limited to, at least the following One: The current ACR is buffered into the ACR queue in the local storage, and the current ACR is sent to the second charging data function unit.

Optionally, in this embodiment, the foregoing predetermined sequence may include, but is not limited to, a constant arranged in ascending order, for example, the predetermined sequence includes 10 consecutive natural numbers: 3, 4, 5, 6, 7, 8, 9, 10 11,11, assuming that the target value obtained by the random number is 9, and the sequence number of the target value in the predetermined sequence is 8, the acquisition percentage P of the target value can be obtained as follows:

P=(7/10)*100%=70%

It should be noted that the value in the foregoing predetermined sequence may be a continuous constant or other constants that are discontinuous. The above is only an example, and is not limited in this embodiment.

Specifically, the following example is used to illustrate that after the CTF normally sends the ACR to the first charging data function unit, the ACA that is processed and returned by the first charging data function unit is obtained. The identifier information supporting the Diameter Overload Indication Conveyance (DOIC) is carried in the ACR message. Then, the first billing data function unit can determine the percentage of load reduction required on the billing interface (ie, the percentage of overload control reduction) according to the load situation (eg, CPU occupancy rate, etc.), and will carry the overload control reduction percentage ( For example, OC-Reduction-Percentage) overload control reduction percentage information and overload control identification are sent to the CTF in the form of a combined AVP overload report (eg, OC-OLR) in the response message ACA.

Optionally, after receiving the reduced percentage information (eg, OC-Reduction-Percentage) carrying the overload control and the response message ACA identified by the required overload control algorithm, the CTF determines the overload control indicated by the percentage reduction information of the overload control. Whether the percentage reduction reaches a threshold that requires overload control (this threshold can be configured by the operator), if it is found that the threshold requiring overload control is reached, the corresponding overload control operation is performed.

For example, assuming that the proportional cache is taken as an example, the overload control reduction percentage indicated by the overload control reduction percentage information is 80%. For the current ACR in the new ACR message (ACR[Start] and its subsequent ACR[Interim] and ACR[Stop]), the following operations are performed: when the current ACR is transmitted, the target value is randomly obtained from the predetermined sequence 1-100 ( For example, the target value is 60), and the predetermined sequence contains a total of 100 values, wherein the target number (ie, 60) has a serial number of 60 in the predetermined sequence, and the acquisition percentage of the target value is 60%, and the comparison yields 60. %<80%, will Current ACR cache.

For another example, assume that when the current ACR is transmitted, the target value is randomly acquired from the predetermined range 1-100 (for example, the target value is 90), and the sequence number of the target value in the predetermined sequence is obtained, where the target value 90 is in the predetermined sequence (1) The serial number in -100) is 90, the percentage of acquisition is 90%, and the comparison yields 90%>80%, then the current ACR is normally sent to the first CDF.

It should be noted that, in the above example, the overload control reduction percentage is 80%, that is, in this embodiment, 80% of the ACR cache to be sent is to be sent, and more than 80% of the ACR to be sent are sent to the first. CDF, so that 80% of the ACR cache to be sent according to the probability distribution is sent, and 20% of the ACR to be sent is normally sent to the first CDF, so as to accurately control the ACR to be buffered according to the percentage of overload control reduction, and the accuracy of the overload control is improved. Sex.

Optionally, in this embodiment, the manner of utilizing the target value within the predetermined range and the percentage of reduction of the overload control is not limited to the above example, for example, the size of the molecule whose target value and the percentage of the overload control decrease are directly compared, thereby determining Whether to cache the corresponding current ACR to be sent. This embodiment does not limit this.

Through the embodiment provided by the present application, real-time judgment of the current ACR is realized by the above-mentioned manner of performing the overload control operation proportionally, so that when the overload is found, the overload control is performed in time, thereby avoiding the first calculation caused by continuing to send the ACR. The processing load of the fee data function unit is increased, and the overload is increased, thereby achieving an effect of improving the accuracy of the overload control of the first billing data function unit.

As an optional solution, performing an overload control operation on the current ACR according to the overload control mode indicated by the overload control flag includes:

S1, an overload control operation is performed for each current ACR.

Optionally, in this embodiment, the foregoing overload control operation may include, but is not limited to, at least one of: buffering the current ACR into an ACR queue in the local storage, and transmitting the current ACR to the second charging data function unit.

Specifically, in combination with the following example, after the charging trigger function unit CTF normally sends the ACR to the first charging data function unit (ie, the first CDF), the charging request response message ACA that is normally processed and returned by the first CDF is acquired. Wherein, the ACR message carries the support overload indication transmission (DOIC, Diameter Overload Indication Conveyance) identification information. Then, the first CDF can determine the percentage of load reduction required on the charging interface (ie, the percentage of overload control reduction) according to the load situation (eg, CPU occupancy rate, etc.), and will carry the overload control reduction percentage (eg, OC- Reduction-Percentage) The overload control reduction percentage information and overload control flag are sent to the CTF in the form of a combined AVP overload report (eg, OC-OLR) in the response message ACA.

For example, assume that the current ACR is all transmitted to the second charging data function unit (ie, the second CDF) as an example. For new ACR messages (ACR[Start] and its subsequent ACR[Interim] and ACR[Stop]), the CTF selection will put all new ACR messages and their corresponding subsequent ACR[Interim] and ACR[Stop] messages. All are forwarded to the second CDF and receive an accounting response message from the second CDF.

Through the embodiment provided by the present application, when the current ACR is sent, the overload control operation is performed on all ACRs, thereby avoiding the processing load of the first charging data function unit caused by continuing to send the ACR, and the problem of overloading is avoided. Further, the effect of alleviating the processing pressure of the first billing data function unit is achieved.

As an optional solution, performing an overload control operation on the current ACR according to the overload control mode indicated by the overload control flag includes at least one of the following:

S1, buffering the current ACR into the ACR queue in the local storage according to the overload control mode indicated by the overload control identifier; or

S2: Send the current ACR to the second charging data function unit according to the overload control mode indicated by the overload control flag.

Specifically, in conjunction with the example shown in FIG. 3, the flow of the overload control method of the charging request message shown in FIG. 3 may include steps S302 to S318:

S302, in the core network element 32 (located at the Diameter client 38), the DiameterACR is normally sent to the primary CDF 34 (located on the Diameter server 39);

S304. The main CDF 34 carries the current overload control reduction percentage information (OC-Reduction-Percentage) and the overload control identifier (OC-OLR) in the Diameter ACA according to the current load situation.

S306. The primary CDF 34 sends the Diameter ACA to the core network element 32.

Optionally, in S308, the core network element 32 determines whether the primary CDF 34 is overloaded according to the overload control reduction percentage indicated by the overload control reduction percentage information;

S310. If it is determined that the main CDF 34 is overloaded, the overload control operation is performed proportionally according to the overload control method indicated by the overload control flag. For example, using a random algorithm to generate a value between 1 and 100, when the resulting value is less than or equal to the percentage of the overload control reduction percentage, the current ACR buffer to be sent, when the resulting value is greater than the 5% of the overload control reduction factor, The current ACR to be transmitted is sent to the main CDF 34.

Optionally, in step S312, the current ACR to be transmitted is sent to the primary CDF 34.

In addition, if the overload control is performed in a manner that the current ACR to be sent by the CTF is sent to the secondary CDF 36, the current ACR to be sent is sent to the secondary CDF 36 in step S314, where the currently sent ACR to be transmitted includes the DOIC. The charging identification information is such that the secondary CDF 36 processes the current ACR to be transmitted, as by step S316.

Optionally, in step S318, the core network element 32 determines whether the overload control reduction percentage indicated by the overload control reduction percentage information returns to the normal range, and if it is determined that the normal range is returned, the overload status of the primary CDF is released. , you can control the ACR in the ACR queue to be sent in order.

It should be noted that, with reference to the previously described examples, the foregoing is only an example, and is not limited in this embodiment.

With the embodiment provided by the present application, the first billing number is not controlled by proportionally controlling the current ACR to be sent to the local storage or to the second charging data function unit. The ACR is sent according to the functional unit to perform overload control on the first charging data function unit in advance to avoid overloading due to overload control lag.

As an optional solution, after performing an overload control operation on the current ACR according to the overload control mode indicated by the overload control flag, the method further includes:

S1. Determine whether the charging request message in the first charging data function unit is overloaded.

S2. If it is determined that the charging request in the first charging data function unit has been overloaded, the buffered ACR is sequentially read from the ACR queue in the local storage and sent to the first charging data function unit.

Optionally, in this embodiment, the cached ACRs are sequentially saved to obtain an ACR queue, so that after the first CDF overload state is determined to be released, the buffered ACRs to be sent in the ACR queue are continuously sent. To avoid omissions, and to achieve the effect of optimizing overload control.

Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A better implementation. Based on such understanding, the technical solution of the present invention in essence or the contribution to the related art can be embodied in the form of a software product stored in a storage medium (such as ROM/RAM, disk, CD-ROM). The instructions include a number of instructions for causing a terminal device (which may be a cell phone, computer, server, or network device, etc.) to perform the methods described in various embodiments of the present invention.
