Description

Addressing method, device and equipment of online charging system
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an addressing method, an addressing device, and an addressing apparatus for an online charging system.
Background
As shown in fig. 1, a schematic diagram of a network architecture is defined for a 5GC standard, a control plane adopts a service SBI interface, and according to 3GPP definition, a CCS is composed of a CHF (Charging Function) and an OCS (Online Charging System), but since existing node layouts of operators are different, there is a case where the CHF and the OCS are separately deployed, an interface between the CHF and the OCS on the BOSS side is also exposed in a networking. In 3GPP, the Nchf interface is defined as an SBI service interface providing a charging function for the CHF on the network side, and the CHF provides a file interface for the BOSS, in a manner similar to the Nchf' SBI service interface defining the OCS on the BOSS side and also providing a charging function for the CHF on the network side for charging message transfer. The SMF (Session Management Function) on the 5GC network side serves as a converged charging service user of Nchf. The SMF issues a PDR (Packet Detection Rule) Packet Detection Rule and a URR (usage reporting Rule) usage reporting Rule to a UPF (User plane Function) through an N4 interface, the UPF reports the usage to the SMF at an N4 port according to the received or pre-configured PDR and URR, and the charging information reporting supporting online/offline charging and content charging is realized.
According to the above architecture, the network functions and charging support capabilities are summarized as follows:
CHF supports AGF (Access Gateway Function), CDF (Charging Data Function) and CGF (Charging Gateway Function), AGF receives Charging information sent by SMF side, CDF collects Charging information, generates corresponding CDR (Charging Data Report) and sends the CDR to CGF, and CGF processes CDR and generates a phone bill file for BOSS to collect through a file interface; meanwhile, the CHF supports forwarding a charging request message sent by the SMF to the BOSS, and forwarding a BOSS response to the SMF:
the SMF supports a charging trigger function and charging information acquisition and is used as a user of an Nchf service interface; support for selecting CHF; as a service user, supporting a charging session flow of an Nchf _ ConvergedCharging interface; requesting and receiving a quota; tracking and recording the service usage amount according to quota or threshold; reporting quota usage and service usage to the CHF; processing quota re-authorization triggering conditions and corresponding reporting to CHF; processing the notification; handling fault/exception scenarios; the method supports the issuing of PDR and URR rules of an N4 interface between the UPF and the PCF, collects the charging amount, and supports the control of a charging strategy of an N7 interface between the PCF and the PCF.
As a forwarding node of a charging message, there are the following scenarios that need to forward the charging message:
for online charging, after CHF receives an Nchf message of converged charging from SMF, according to CC identification, it identifies the online charging scene, resolves SUPI (Subscription Permanent Identifier)/GPSI (Generic Public subscriber Identifier) in the message, acquires the home OCS interface address according to the SUPI/GPSI segment, then sends the Nchf message to OCS in the home BOSS system for processing, returns Nchf response message to SMF, and at the same time, CDF generates CDR.
For converged charging, CHF resolves SUPI/GPSI in the message after receiving the converged-charging Nchf message from SMF, acquires home OCS interface address according to SUPI/GPSI segment, then forwards the Nchf message to home BOSS, returns Nchf response message to SMF, and generates CDR by CDF.
Considering the above scenario, the CHF node needs to have the addressing capability for the OCS. In view of the above requirements, considering the 4G to 5G evolution direction, there are the following schemes:
the CHF is responsible for routing and forwarding the charging message generated by the SMF to the BOSS of the home location according to the routing and forwarding rule.
For the session class messages (Nchf _ convergedlocking _ Create, Nchf _ convertedlocking _ Update, Nchf _ convertedlocking _ Release) sent by SMF, CHF routes the BOSS to the home location according to the SUPI/gpsi (imsi) in the charging request message. The routing key information is as follows:
relevant information that CHF needs to configure the BOSS node is:
Figure BDA0002353166390000021
Figure BDA0002353166390000031
the mapping relationship between the SUPI/GPSI and the BOSS (OCS) is configured as follows:
Figure BDA0002353166390000032
after receiving the response message of the BOSS, the CHF forwards the response message to the corresponding SMF according to the original path.
The scheme needs that CHF locally maintains global user code segment information, statically specifies the corresponding relation between code segments and the OCS, and has the limitation that if the OCS in the existing network is too much or the dispersion of the user code segment information is high, the static configuration data volume is huge, the requirement on node performance is high, the subsequent code number information needs to be updated, the OCS side needs to inform all CHF, and the CHF side manually updates and configures synchronous user data change.
