Error Codes

Following table lists the error codes that SMF uses for error handling:

Error Codes with Details

Number

Enum

Details

SMF Support

1

UNK_RULE_ID

Indicate that the preprovisioned PCC rule isn't activated. This error occurs when SMF has no information on the PCC rule identifier.

Yes

2

RA_GR_ERR

Indicate that the PCC rule isn't activated or enforced. This error occurs when the PCC rule referring to the specified Rating Group, in the Charging Data policy decision, is unknown or invalid.

Yes

3

SER_ID_ERR

Indicate that the PCC rule isn't activated or enforced. This error occurs when PCC rule referring to the specified service identifier, in the Charging Data policy decision, is invalid, unknown, or not applicable to the service being charged.

Yes

4

NF_MAL

Indicate that the PCC rule isn't installed, activated, or enforced due to SMF or UPF functionality issues. The PCC rule installation is for the rules provisioned from PCF. The PCC rule activation is for the rules predefined in SMF. The PCC rule enforcement is for the installed rules.

No

5

RES_LIM

Indicate that the PCC rule isn't installed, activated, or enforced due to limitation of resources at the SMF or UPF.

No

6

MAX_NR_QoS_FLOW

Indicate that a PDU session has reached the maximum number of QoS flows.

Yes

7

MISS_FLOW_INFO

Indicate that the PCC rule isn't installed. This error occurs when PCF fails to specify either the "flowInfos" attribute or the "appId" attribute in the PccRule data structure during the first installation request of the PCC rule.

Yes

8

RES_ALLO_FAIL

Indicate that the PCC rule isn't installed or maintained. This error occurs due to the QoS flow establishment, modification failure, or release of the QoS flow.

Yes

9

UNSUCC_QOS_VAL

Indicate QoS validation failure or when the Guaranteed Bandwidth is more than the maximum requested bandwidth.

Yes

10

INCOR_FLOW_INFO

Indicate that the PCC rule isn't installed or modified at SMF. This error occurs when the network doesn't support the flow information, such as IP address or an IPv6 prefix doesn't correspond to the applicable IP version for the PDU session.

Yes

11

PS_TO_CS_HAN

Indicate that the PCC rule isn't maintained due to packet switched (PS) to circuit switched (CS) handover.

No

12

APP_ID_ERR

Indicate that the PCC rule isn't installed or enforced. This error occurs due to invalid, unknown, or nonapplicable application identifier that an application requires for detection.

No

13

NO_QOS_FLOW_BOUND

Indicates that no QoS flow exists for the SMF to associate the PCC rules to.

Yes

14

FILTER_RES

Indicates that the SMF is unable to handle the flow information in "flowInfos". This error occurs when the restrictions defined in subclause 5.4.2 of 3GPP TS 29.212 [23] aren't met.

Yes

15

MISS_REDI_SER_ADDR

Indicate that the PCC rule isn't installed or enforced at the SMF. This error occurs when PCF doesn't provide a valid redirect server address in the Traffic Control Data policy decision for the PCC rule and no pre-configured redirection address for this PCC rule exists at the SMF.

No

16

CM_END_USER_SER_DENIED

Indicate that the charging system denied the service request due to service restrictions. For example, termination of rating group or end-user related limitations, such as the end-user account doesn't include the requested service.

No

17

CM_CREDIT_CON_NOT_APP

Indicate that the charging system determined that the service can be granted to the end user. However, no credit control is applicable for the service. For example, a service is free of charge or available for offline charging.

No

18

CM_AUTH_REJ

Indicate that the charging system denied the service request to terminate the service for which an end user requested a credit.

No

19

CM_USER_UNK

Indicate that an end-user information in unavailable in the charging system.

No

20

CM_RAT_FAILED

Indicate that the charging system can't rate the service request. This error occurs due to insufficient rating input, incorrect AVP combination, or because of an unrecognized or unsupported attribute value in the rating.

No

21

UE_STA_SUSP

Indicates that the UE is in the suspended state.

Note

This error is applicable only to the interworking scenario, as defined in Annex B of the 3GPP specification.

No
