5.8.5.5 Usage Reporting Rule
Taught in 13. Where the packets actually go (The 5G system architecture, in depth), 5. The connection, and what is promised on it (The 5G system architecture, overview).
The following table describes the Usage Reporting Rule (URR) that defines how a packet shall be accounted as well as when and how to report the measurements.
Table 5.8.5.5-1: Attributes within Usage Reporting Rule
| Attribute | Description | Comment |
|---|---|---|
| N4 Session ID | Identifies the N4 session associated to this URR | |
| Rule ID | Unique identifier to identify this information. | Used by UPF when reporting usage. |
| Reporting triggers | One or multiple of the events can be activated for the generation and reporting of the usage report. | Applicable events include:- Start/stop of traffic detection with/without application instance identifier and deduced SDF filter reporting; Deletion of last PDR for a URR; Periodic measurement threshold reached; Volume/Time/Event measurement threshold reached; Immediate report requested; Measurement of incoming UL traffic; Measurement of discarded DL traffic; MAC address reporting in the UL traffic; unknown destination MAC/IP address; end marker packet has been received. |
| Periodic measurement threshold | Defines the point in time for sending a periodic report for this URR (e.g. timeofday). | This allows generation of periodic usage report for e.g. offline charging.It can also be used for realizing the Monitoring time of the usage monitoring feature.It can also be used for realizing the Quota-Idle-Timeout, i.e. to enable the CP function to check whether any traffic has passed during this time. |
| Volume measurement threshold | Value in terms of uplink and/or downlink and/or total byte-count when the measurement report is to be generated. | |
| Time measurement threshold | Value in terms of the time duration (e.g. in seconds) when the measurement report is to be generated. | |
| Event measurement threshold | Number of events (identified according to a locally configured policy) after which the measurement report is to be generated. | |
| Inactivity detection time | Defines the period of time after which the time measurement shall stop, if no packets are received. | Timer corresponding to this duration is restarted at the end of each transmitted packet. |
| Event based reporting | Points to a locally configured policy which is identifies event(s) trigger for generating usage report. | |
| Linked URR ID(s) | Points to one or more other URR ID. | This enables the generation of a combined Usage Report for this and other URRs by triggering their reporting. See clause 5.2.2.4, TS 29.244 [65]. |
| Measurement Method | Indicates the method for measuring the network resources usage, i.e. the data volume, duration, combined volume/duration, or event. | |
| Measurement information | Indicates specific conditions to be applied for measurements | It is used to request:- measurement before QoS enforcement and/or- to pause or set to active a measurement as for the Pause of charging described in clause 4.4.4 and clause 4.23.14 of TS 23.502 [3] and/or- to request reduced reporting for application start/stop events. |
