Description

Online charging message access layer authorization and call ticket instantiation method and device

Technical Field

The invention relates to the technical field of data service, in particular to a method and a device for online charging message access layer authorization and call ticket instantiation.

Background

With the development of speed-increasing and cost-reducing work of telecommunication operators, mobile communication data services are growing explosively, a large number of service requests put high resource demands on a BOSS (service Support System), and each year, the investment of network element devices such as GGSN (Gateway general packet radio service Support Node), Gateway GPRS Support Node/P-GW (data Gateway, PDN Gateway) and the like, and OCS (Online Charging System) processing clusters, network transmission and storage devices is increased year by year, and the investment is a heavy burden of the operators. In order to meet the demand of hardware resources rapidly rising year by year, reduce the hardware investment pressure and provide a hardware equipment deployment idea for 'IOE' for various telecom operators in the aspect of a basic platform, expensive small computers, centralized storage and an Oracle database are replaced by cheap X86 equipment, distributed storage and an open source relational database, and a dynamic authorization scheme relying on an online charging system is a better idea for solving the problem of overlarge resource occupation in the aspects of business and software.

The online charging is to carry out resource authorization, connection release, real-time settlement and credit control through Diameter message interaction, thereby well solving the problems of high time delay, high defaulting and other service operation short boards caused by the traditional offline ticket charging mode, and greatly improving the efficiency in the aspects of pricing, closing accounts, credit control, reminding and the like. The online charging can dynamically and flexibly reduce the number of messages reported by GGSN/P-GW (Credit-Control-Request) according to factors such as user fee package, residual resource amount, Internet access rate, etc. by adjusting the authorization amount or specifying the message reporting reason by CCA (Credit-Control-Answer), etc., thereby greatly reducing the requirements of CPU, memory, storage and network transmission. However, the service support system needs to adapt to the evolution of the service marketing mode, the version upgrading and reconstruction frequency is high, and each time the rear end of the service support system is cut off and upgraded, the common method is to terminate the message receiving and processing process at the rear end of the service support system, and after the message access layer of the service support system does not respond to the detection message processing layer, the message access layer of the service support system can carry a 3002 abnormal return code on the Command layer of the CCA, so as to indicate that the GGSN/P-GW changes to the offline Charging flow, and the basis of the Charging flows such as pricing, reminding, and signal control is that a CG (Charging Gateway) issues an offline ticket, so that the problems of high arrearage and high time delay caused by offline Charging cannot be solved. When a session needs to be switched from offline to online, the GGSN/P-GW deletes the PDP connection of the user only by waiting for the user to actively initiate the PDP (Packet Data Protocol) connection reestablishment (such as shutdown or flight mode), or the user stops using the service beyond the IDLE threshold, the whole process takes a long time, and the normal online rate can be gradually recovered after several days or even one week. The problem that the customer perception is seriously influenced by high arrearage, excessive charge, reminding delay and the like caused by the fact that the user data service in the large-area service area is switched off is solved, the dynamic authorization capability of online charging is lost, an offline call ticket can only be issued by a fixed call ticket cutting threshold (usually 10M/20M in time is 1800 seconds and other experience values), the number of the call tickets cannot be effectively reduced, the time for replanting the call tickets after the call ticket cutting and upgrading is finished is too long, and the income guarantee and the customer perception are seriously influenced.

Therefore, how to ensure that the user charging session is online when the rear end of the support system is cut over and upgraded, and adjust the number of messages or call tickets in a reasonable manner, so as to accelerate the processing efficiency of the system, meet the normal development of services, reduce the income loss and poor customer perception caused by the cut-over window, and is a problem to be solved by the current telecom operators.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 shows a flowchart of an online charging message access layer authorization and ticket instantiation method according to an embodiment of the invention. As shown in fig. 1, the method for authorizing the access layer of the online charging message and instantiating the call ticket specifically includes the following steps:

step S101, according to the packet data protocol PDP context creation request of the user, triggering the online charging process.

When a user needs to use a user terminal to connect to the network or use network traffic data, a PDP context creation request is sent. Specifically, the user terminal sends a PDP context creation request to the gateway gprs support node GGSN/data gateway P-GW. After receiving a PDP context creation request of a user, the method can correspondingly trigger the online charging processing of the user so as to calculate the flow data used by the user and facilitate the subsequent generation of call tickets and the like.

Step S102, receiving a credit control request CCR message carrying connection establishment sent by a gateway general packet radio service support node GGSN/data gateway P-GW, and determining a flow quota for distribution according to the availability state of a message processing layer.

The business support system BOSS includes many layers, such as a message access layer, a message processing layer, and the like. The message access layer of the BOSS can receive various CCR messages sent by a gateway GPRS support node GGSN/P-GW, and carry out corresponding processing according to the CCR messages. When GGSN/P-GW creates request according to PDP context of user, after triggering on-line charging process, GGSN/P-GW sends CCR message carrying connection establishment to message access layer. The CC-Request-Type value in the CCR message (CCR-Initial message) may be set to e.g. INITIAL _ REQUEST for establishing a DCC connection. Further, a rate group quota corresponding to the application of non-content charging (for example, the rate group quota is set to n) may be set in the CCR message, and a Requested-Service-unit (rsu) field in the MSCC AVP may be set to null, and the like. GGSN/P-GW can flexibly configure CCR message, such as setting whether to apply quota in CCR message and applying rate group of quota.

For the message processing layer, in the prior art, when the BOSS system is upgraded, the message processing layer cannot carry service processing, and after the message access layer detects that the message processing layer has no response, the message access layer returns a 3002 abnormal return code to instruct the GGSN/P-GW to switch to offline charging. In view of the above problems, in the embodiment, after the message access layer receives the CCR message carrying the connection establishment credit control request sent by the GGSN/P-GW, it is first determined whether the available state of the message processing layer is unavailable; namely, whether the BOSS system is upgrading is judged, and if the available state of the message processing layer is unavailable, namely the BOSS system is upgrading and user information which cannot be acquired is obtained, the flow quota is determined to be a preset fixed value. Rather than returning the exception return code directly, online charging can be performed using the traffic quota. The flow quota is a quota reserved for the user in advance, and comprises a current flow quota application value and a current time quota application value. The preset fixed value of the current flow quota application value may be, for example, 50M, and the current time quota application value may be, for example, 5 minutes, and the like.

Step S103, monitoring the data flow used by the user, when the data flow used by the user meets the reapplication condition compared with the flow quota, receiving the reported used flow quota as a session and storing the session in a cache, and determining the flow quota again for distribution until receiving the CCR message which is sent by GGSN/P-GW and carries the termination information.

When the data stream used by the user is compared with the allocated flow quota and the reapplication condition is met, the flow quota needs to be allocated to the user again. Specifically, when the flow value of the data stream used by the user this time reaches a preset threshold of the current flow quota application value (for example, 80% of the current flow quota application value, which is described above as an example and is not limited here), or when the usage time of the flow quota used by the user this time exceeds the current time quota application value, the re-application condition is satisfied. And the GGSN/P-GW sends the CCR message of the quota request to the message processing layer again, and the message access layer determines the flow quota for the user again. The re-determined flow quota may use the same preset fixed value as the first-determined flow quota, or may use a different preset fixed value according to the number of times of re-requests, which is not limited herein. Furthermore, besides determining the flow quota again to be allocated by the message access layer, the used flow quota reported by the GGSN/P-GW needs to be received and stored in the cache as the information of the session, so as to facilitate the subsequent combination processing of the used flow quota and reduce the problem that a large amount of ticket data is generated by instantiating the ticket in a single session.

The step can continuously monitor the data stream generated by the user, when the data stream generated by the user and the distributed flow quota meet the reapplication condition each time, the message access layer is required to determine the flow quota again for distribution, and the repeated execution is carried out until the message access layer receives the CCR message which is sent by the GGSN/P-GW and carries the termination information, and the flow quota distribution is not continued any more

And step S104, combining the plurality of sessions in the cache and instantiating the call ticket.

After the message access layer receives the CCR message which is sent by GGSN/P-GW and carries the termination information, the message access layer combines a plurality of sessions which are stored in the cache, instantiates a ticket for the combined session, namely writes the combined session into a ticket file, and completes the online charging.

According to the online charging message access layer authorization and call ticket instantiation method provided by the invention, the defaulting can be effectively reduced, the reminding and the signal control timeliness are improved, the utilization rate of system resources is greatly reduced, and the method has a remarkable effect on the compression of the investment of a BOSS system, network element equipment and transmission equipment.

Fig. 2 shows a flowchart of an online charging message access stratum authorization and ticket instantiation method according to another embodiment of the present invention. As shown in fig. 2, the method for authorizing the access layer of the online charging message and instantiating the call ticket specifically includes the following steps:

step S201, receiving the packet data protocol PDP context creation request of the user through the gateway GPRS support node GGSN/data gateway P-GW.

When a user terminal, such as a mobile phone, a pad, and other wireless network mobile devices, needs to access a network and use mobile data, such as traffic, it sends a PDP context creation request to establish a network connection, which is convenient for a subsequent user terminal to use data, such as traffic. The GGSNs mainly correspond to 2G and 3G networks and the P-GWs mainly correspond to 4G networks or 5G networks (and subsequent network levels). A packet data protocol PDP context creation request for the user may be received by the GGSN/P-GW. In addition to the PDP context creation request sent by the user terminal, a user default bearer creation request may also be sent. In this embodiment, a PDP context creation request is taken as an example for explanation, and for the processing of the user default bearer creation request, the PDP context creation request may be referred to for corresponding processing, which is not described herein.

In connection with the flow chart shown in fig. 3, the user terminal sends a PDP context creation request to the GGSN/P-GW.

Step S202, according to the PDP context creation request, the online charging process is triggered.

After the GGSN/P-GW receives the PDP context creation request, the GGSN/P-GW judges according to the charging characteristic field carried by the PDP context creation request, wherein the charging characteristic field is, for example, ChargingCharacteristics, which records whether the user is a real-time charging user, if the user is judged to be the real-time charging user, the online charging processing is triggered, and the data used by the user is charged online by using the BOSS. And if the user is judged to be a non-real-time charging user, processing the user according to normal offline charging.

Referring to the flowchart shown in fig. 3, after the GGSN/P-GW determines the real-time charging user, the online charging process is triggered.

Step S203, receiving the message access layer of the gateway GPRS support node GGSN/data gateway P-GW to send the message carrying the credit control request CCR message for establishing the connection to the business support system BOSS, and determining the flow quota for distribution by the message access layer according to the available state of the message processing layer.

After the GGSN/P-GW determines that the user is a real-time charging user, the GGSN/P-GW sends a CCR message to a message access layer of the service support system BOSS, and the specific content of the CCR message (CCR-Initial message) refers to the description in step S102, which is not described herein again.

After receiving a credit control request CCR message carrying connection establishment sent by GGSN/P-GW, a message access layer firstly judges whether the available state of a message processing layer is unavailable or not; namely, whether the BOSS system is upgrading is judged, and if the available state of the message processing layer is unavailable, namely the BOSS system is upgrading and user information which cannot be acquired is obtained, the flow quota is determined to be a preset fixed value. Rather than returning the exception return code directly, online charging can be performed using the traffic quota. If the available state of the message processing layer is available, the flow quota can be determined according to the user information. The user information comprises user package information, a user flow residual value, a user balance and the like, and can be acquired through the message processing layer. And determining the flow quota according to the actual user information, and directly carrying out online charging on the flow quota.

With reference to the flowchart shown in fig. 3, that is, the GGSN/P-GW sends a CCR message to the message access layer to establish a connection, the message access layer determines whether the message processing layer is in an unavailable state, and when the message processing layer is in an unavailable state, the message access layer traffic quota is a preset fixed value. A CCA message is answered with credit control. If the CCR message sent by the GGSN/P-GW to the message access layer does not include the service request unit RSU field, the Result Code of Command level in the CCA message sent by the BOSS is 2001, and if the CCR message sent by the GGSN/P-GW to the message access layer includes the RSU field, the Result codes of Command level and MSCC level in the CCA message sent by the BOSS are 2001. The CCA message includes Granted-Service-Unit AVP(s) allocated flow quota, the flow quota is issued by CC-Total-Octets AVP, and quotas allocated by GSU (Granted-Service-Unit, current flow quota application value) and VT (current Time quota application value, Validity-Time) are preset fixed values. VQT (Volume-quote-Threshold of the current flow Quota application value) can also be a preset fixed value.

Step S204, GGSN/P-GW authorizes the user terminal to use the service, and sends PDP context creation response.

As shown in fig. 3, after receiving the CCA message, the GGSN/P-GW may authorize the user terminal to send a PDP context response message or a default bearer creation response message using the corresponding data service. The user can use the allocated traffic quota to generate a data stream.

Step S205, monitoring the data flow used by the user, when the data flow used by the user meets the reapplication condition compared with the flow quota, sending a credit control request CCR message to the message access layer of the BOSS through GGSN/P-GW again, reporting the used flow quota and storing the reported flow quota as a session in a cache; and the message access layer determines the flow quota again for distribution until the GGSN/P-GW sends the CCR message carrying the termination information.

As shown in fig. 3, the GGSN/P-GW monitors the data stream used by the user, and when the data stream used by the user meets a reapplication condition compared with the traffic Quota, that is, when the traffic Quota allocated to the user is about to be used up (when the traffic value of the data stream used by the user this Time reaches a Volume-Quota Threshold) or is about to expire (when the usage Time of the traffic Quota used by the user this Time exceeds a Validity-Time), the GGSN/P-GW retransmits the CCR message to the message access layer of the service support system BOSS, reports the used traffic Quota and stores the reported traffic Quota in the cache as a session, and the reporting reason is that the traffic value of the data stream used by the user reaches a minimum Quota Threshold (reporting-delay) or the Quota authorized valid Time ends (reporting-delay _ Time). The CC-Request-Type of the retransmitted CCR message (CCR _ Update message) is set to UPDATE _ REQUEST. Further, when the allocated traffic Quota is not used within a certain period of Time, and the idle timer value quote-Holding-Time specified in the last CCA message is reached, the GGSN/P-GW will also send a CCR message, with CC-Request-Type set to UPDATE _ Request. At this time, the CCR message carries an MSCC AVP containing quota consumption information, and the MSCC contains a Unit Used-Service-Unit AVP identifying the actual use of the Service, and a Request-Service-Unit AVP identifying a requested traffic quota.

And the message access layer distributes the flow quota for the user again and returns the corresponding flow quota to the GGSN/P-GW through the CCA message. The CCR message (CCR _ Update message) and the CCA message are sent multiple times according to the actual situation until the GGSN/P-GW sends a CCR message (CCR-Terminate message) carrying termination information to the message access layer. The CC-Request-Type AVP of the CCR message carrying TERMINATION information is set as TERMINATION _ Request, the CCR message comprises an Event-Timestamp AVP for identifying Service TERMINATION time and a Used-Service-Unit AVP for identifying the Unit actually Used by the Service, and the CCR message does not contain the Request-Service-Unit AVP for identifying the Request quota any more.

Further, when storing the Session, the message access layer will judge in advance whether the Session exists, if not, create a Session linked list with the identifier of GGSN and Session-ID, and write the information of number, SGSN, APN, RAT, Charging-ID, etc. into the structural body to insert into the Session linked list.

Step S206, merging the multiple sessions in the cache, and instantiating the call ticket.

In fig. 3, after receiving a CCR message (CCR-termination message) terminating connection sent by a GGSN/P-GW, a message access layer combines multiple sessions in a cache, and instantiates a ticket. Returning the CCA message responds that the connection is terminated with a CCR message (CCR-Terminate message). When merging the conversation, the message access layer merges the current conversation, the summary duration, the up and down usage amount and other information according to GGSN and Session-ID in the conversation chain table.

Further, in the actual processing, the message access layer combines the multiple sessions in the cache, and not only receives the CCR message (CCR-termination message) sent by the GGSN/P-GW. Specifically, the message access layer determines whether a plurality of sessions in the cache satisfy preset conditions, where the preset conditions include various situations such as that traffic generated by the sessions reaches a preset singulation threshold, the sessions are overtime, and the sessions are normally terminated (CCR-Terminate messages sent by GGSN/P-GW are received). When any preset condition is met, the message access layer can combine the sessions in the session linked list, and write the combined sessions into a ticket file to realize the instantiation ticket. Namely, when the user session is normally terminated (a CCR-Terminate message sent by GGSN/P-GW is received), or the session is overtime, or the flow generated by the session reaches a preset list cutting threshold or other charging conditions, the session in the cache is combined into a call ticket and written into a file to serve as a subsequent rating basis.

Further, a preset list switching threshold value of the message access layer can be configured according to the cut-over scene, if offline charging is still available, the preset list switching threshold value can be configured to be smaller, the requirement of service precision is met, and if online charging and offline charging are both suspended, the preset list switching threshold value can be configured to be larger, and the call ticket approval rate is accelerated.

Step S207, delete the session stored in the cache to release the cache resource.

Specifically, the session stored in the cache can be deleted by deleting the current session linked list, so that resources such as the cache and the like are released.

According to the online charging message access layer authorization and call ticket instantiation method provided by the invention, the message access layer in the prior art has no call ticket instantiation function, the call ticket combination threshold value can not be adjusted according to the service scene, if online charging cut-over is upgraded and offline charging is available, the combination threshold value is reduced to improve the reminding and signal control precision, and if online charging and offline charging are temporarily unavailable, the combination threshold value is expanded to improve the call ticket tracing efficiency after cut-over. The invention can effectively reduce arrearage, improve prompt and signal control timeliness, greatly reduce the utilization rate of system resources, and has obvious effect on the investment of a compression BOSS system, network element equipment and transmission equipment.

Each feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise.

Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments may be used in any combination.

The various component embodiments of the invention may be implemented in hardware, or in software modules running on one or more processors, or in a combination thereof. It will be understood by those skilled in the art that a microprocessor or Digital Signal Processor (DSP) may be used in practice to implement some or all of the functions of some or all of the components of the online charging message access layer authorization and ticket instantiation apparatus according to the embodiments of the present invention. The present invention may also be embodied as apparatus or device programs (e.g., computer programs and computer program products) for performing a portion or all of the methods described herein. Such programs implementing the present invention may be stored on computer-readable media or may be in the form of one or more signals. Such a signal may be downloaded from an internet website or provided on a carrier signal or in any other form.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The invention may be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In the unit claims enumerating several means, several of these means may be embodied by one and the same item of hardware. The usage of the words first, second and third, etcetera do not indicate any ordering. These words may be interpreted as names.
