Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an addressing method, apparatus, and device for an online charging system.
Background
As shown in fig. 1, a network architecture is defined for the 5GC standard, the control plane adopts a service SBI interface, and according to the 3GPP definition, the CCS is composed of CHF (Charging Function ) and OCS (Online Charging System, online charging system), but because of different existing node layout conditions of each operator, there may be a situation that CHF and OCS are deployed separately, so that the interface between CHF and the OCS on the BOSS side is also exposed in the networking. In 3GPP, nchf interface is defined to provide SBI service interface of charging function for CHF at network side, then OCS at BOSS side is analogically defined to provide Nchf' SBI service interface of charging function as well, CHF at network side is used for charging message transmission, and CHF provides file interface for BOSS. The 5GC network side SMF (Session Management Function ) acts as a converged billing service user for Nchf. The SMF transmits PDR (Packet Detection Rule, message detection rule) packet detection rule and URR (usage reporting rule, usage report rule) usage reporting rule to UPF (User plane Function ) through N4 interface, UPF reports usage to SMF according to received or preconfigured PDR and URR at N4 interface, and supports online/offline charging and charging information reporting of content charging.
According to the architecture described above, the network functions and charging support capabilities are summarized as follows:
CHF supports AGF (Access Gateway Function ), CDF (Charging Data Function, charging data function) and CGF (Charging Gateway Function ) functions, the AGF receives charging information sent by the SMF side, the CDF collects the charging information, generates a corresponding CDR (Charging Data Report ) and sends the CDR to the CGF, and the CGF processes the CDR to generate a ticket file for the BOSS to collect through a file interface; meanwhile, CHF supports forwarding charging request messages sent by SMF to BOSS and forwarding BOSS responses to SMF:
SMF supports charging triggering function and charging information collection as user of Nchf service interface; support selection of CHF; as a service user, supporting the charging session flow of the Nchf_ConvergedCyarging interface; requesting and receiving a quota; tracking and recording service usage according to quota or threshold; reporting quota usage and service usage reports to CHF; processing quota re-authorization triggering conditions and reporting the quota re-authorization triggering conditions to CHF correspondingly; processing the notification; processing fault/anomaly scenarios; the method supports the PDR and URR rule issuing and charging quantity collection of an N4 interface between UPF and the PCF, and supports the charging policy control of an N7 interface between PCF and PCF.
CHF is used as a forwarding node for charging messages, and there are the following scenarios in which charging message forwarding is required:
for online charging, after CHF receives an Nchf message of converged charging from SMF, it identifies an online charging scenario according to CC identification, analyzes SUPI (Subscription Permanent Identifier) user permanent identifier)/GPSI (Generic Public Subscription Identifier, general public user identifier) in the message, obtains a home OCS interface address according to SUPI/GPSI segment, then sends the Nchf message to OCS in the home BOSS system for processing, sends an Nchf response message to SMF, and generates CDR by CDF.
For converged charging, after CHF receives the converged charging Nchf message from SMF, resolving SUPI/GPSI in the message, obtaining the home OCS interface address according to SUPI/GPSI section, then forwarding the Nchf message to home BOSS, returning an Nchf response message to SMF, and generating CDR by CDF.
In view of the above scenario, CHF nodes need to have addressing capability to OCS. In view of the above requirements, considering the direction of 4G to 5G evolution, there are the following schemes:
CHF is responsible for routing billing messages generated by SMF to the BOSS of the home location according to routing rules.
For session class messages (nchf_convergedcharg_create, nchf_convergedcharg_update, nchf_convergedcharg_release) sent by the SMF, CHF routes to the BOSS of the home location according to the SUPI/GPSI (IMSI) in the charging request message. The routing key information is as follows:
the relevant information that CHF needs to configure a BOSS node is:
the mapping relation between the configuration SUPI/GPSI and the BOSS (OCS) is as follows:
after the CHF receives the response message of the BOSS, the response message is forwarded to the corresponding SMF according to the original path.
The proposal needs CHF to maintain global user code segment information locally and statically designates the corresponding relation between code segments and OCS, and has the limitation that if the OCS of the existing network is too much or the code segment information of the user is high in dispersion, the static configuration data amount 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 needs to manually update and configure synchronous user data change.
