Description

Method for implementing billing, TNE, FCS, BD entity and system

Technical field

The present invention relates to the field of communications, and in particular, to a method for implementing charging, a TNE, an FCS, a BD, and a system.

Background technique

In the 3GPP network, the charging system is one of the important functional systems, including an offline charging system and an online charging system. The offline charging process does not affect the user's use of the telecommunication service in real time, and the offline user is the post-paid user. Online charging affects the user's charging process in real time affecting the user's use of telecommunication services. That is, the user must ensure that the corresponding account balance is sufficient to allow the use of telecommunication services, and the online users are prepaid users.

FIG. 1 is a schematic structural diagram of a charging system defined by 3GPP, as shown in FIG. 1. The access layer network element is used to carry a user access function, such as a Wireless Local Area Network (WLAN), or a Packet Data Network Gateway (PGW). The network element of the control layer is the core network element, which is used to control the route of the user call or session, for example, the service call session control function (SCSCF, Server Call Session Control Function). The service layer network element is used to process a service called by a user or a session, such as a Session Initial Protocol Application Server (SIP AS). Traditional switched network elements are used for traditional circuit switching. The access layer network element, the control layer network element, the service layer network element, and the traditional switching network element are collectively referred to as a TNE (Telecom Network Element). The Offline Charging Server (FCS) is an important functional entity in the offline charging system. The specific functions are described in conjunction with Figure 2. The Online Charging Server (OCS) is an important functional entity in the online charging system. The specific functions are described in conjunction with Figure 3. The billing domain (BD) entity is mainly used for billing processing according to the CDR (Charging Data Record), and is also used for billing related processing, that is, settlement, business analysis, and statistical processing according to the CDR.

2 is a schematic diagram showing the logical composition of an offline charging system in a 3GPP network. As shown in FIG. 2, the offline charging system logically includes a Charging Trigger Function (CTF), FCS and BD. The CTF is embedded in each TNE, and is mainly used for collecting charging information according to the usage of the monitored network resources, and sending an accounting request (ACR, Accounting Request). The FCS logically includes a Charging Data Function (CDF) and a Charging Gateway Function (CGF). The CDF is mainly used to receive the ACR from the CTF, construct and transmit the CDR. The CGF is mainly used to receive, store, and manage CDRs from the CDF, and send CDRs to the BD (in particular, the CDR files carrying one or more CDRs are sent to the BD).

At present, the offline charging process in the offline charging system includes: the TNE embedded with the CTF sends an ACR to the FCS according to the collected charging information; the FCS constructs the CDR according to the obtained ACR, and sends the CDR to the BD; The CDR determines that the user corresponding to the CDR is an offline user by searching the user profile database, and performs charging related processing, that is, charging, settlement, business analysis, and statistical processing.

3 is a schematic diagram showing the logical composition of an online charging system in a 3GPP network. As shown in FIG. 3, it includes: CTF, OCS, FCS, and BD. The CTF has the same function as the CTF in the offline charging system. The OCS logically includes an Online Charging Function (OCF), an RF (Rating Function), and an Account Management Management Function (ABMF). OCF is mainly used to complete the main control and processing flow of online charging for users. RF is mainly used to complete the pricing function according to different services used by users. ABMF is mainly used to complete the user's account balance management function.

At present, the online charging process in the online charging system generally includes: when the prepaid user requests the telecommunication service, the TNE sends an initial charging request (CCR Initial, Charging Credit Request Initial) to the OCS; the OCF in the OCS calls the RF to complete the user's The AMF in the OCS determines whether to pre-authorize the prepaid user according to the result of the rating; if the prepaid user's account balance is sufficient, the OCF in the OCS returns an online charging response (CCA) indicating the successful pre-authorization to the TNE. , Charging Credit Answer), to notify the prepaid user to obtain the pre-authorization; the TNE establishes a corresponding session for the prepaid user and allocates resources according to the obtained CCA, the prepaid user starts to use the requested telecommunication service, and the TNE sends the TNS to the FCS for The ACR indicating the start of the session; the FCS establishes the CDR corresponding to the ACR according to the obtained ACR, and sets the information in the CDR, such as setting the session start time in the CDR as the time for obtaining the ACR; and determining the end of the session to the FCS by the TNE hair The ACR is sent to indicate the end of the session; the FCS sets the information in the CDR corresponding to the ACR according to the obtained ACR, such as setting the session end time in the CDR to the time of obtaining the ACR, sending the CDR to the BD, and deleting the CDR. According to the obtained CDR, the BD determines that the user corresponding to the CDR is a prepaid user by searching the user profile database, and performs settlement related processing.

After the prepaid user starts to use the requested telecommunication service, when the TNE detects an abnormality with the OCS or the OCS (in this case, collectively referred to as an OCS abnormality), the online charging process generally includes: the TNE sends an indication to the FCS to indicate an OCS abnormality. According to the obtained ACR, the OCS abnormality identifier in the CDR corresponding to the ACR is set to be abnormal; when the TNE determines that the session ends, the ACR is sent to the FCS to indicate the end of the session; the FCS sets the ACR according to the obtained ACR. Corresponding CDR, the CDR is sent to the BD, and the CDR is deleted. The BD determines, according to the obtained CDR, that the user corresponding to the CDR is a prepaid user, and determines the CDR in the CDR by using the OCS abnormal identifier in the CDR. Whether the OCS exception has occurred in the corresponding session duration. If the result of the determination is over, the user's deducted fee and the undeducted fee are calculated by searching the historical CDR database, and the calculated undeducted fee is calculated. The fee-related processing performs settlement-related processing based on the calculated deducted fee.

When an OCS exception occurs in the process of using a telecommunication service by a prepaid subscriber, the BD needs to look up the historical CDR database in order to calculate the deducted fee and the undeducted fee of the user. In practice, because a large amount of information is stored in the historical CDR database, it is usually time-consuming and laborious to find historical CDR data, and the time for searching the historical CDR database once is a second time, such as 5 seconds. In this way, when the OCS is abnormal, the BD needs to search the historical CDR database for a large number of CDRs such as tens of thousands or even more prepaid users, which greatly increases the processing complexity of the BD for the CDR of the prepaid user, and significantly reduces the BD. The processing efficiency of the CDR affects the user experience.
