Configuring Cause Code Mapping
Each mapping of a cause code is configured slightly differently. Each is illustrated below.
Configuring GMM Cause Codes to Replace MAP Cause Codes
The following configures the SGSN to include a preferred GMM cause code, in Reject messages to the UE, in place of
MAP failure cause 'unknown-subscriber' for MAP failures and inbound RAU context transfer failures. Optionally, the
Operator can map a specific GMM cause code if the SGSN receives additional MAP failure diagnostic information.

Notes:
unknown-subscriber
Instructs the SGSN to send a different GPRS mobility management (GMM) cause code
to a UE when the UE’s access request is rejected due to map cause ‘unknown-subscriber’.
gmm-cause-code gmm_cause
identifies the replacement GMM cause code; options include:
gprs-serv-and-non-gprs-serv-not-allowed
gprs-serv-not-allowed
gprs-serv-not-in-this-plmn
location-area-not-allowed
network-failure
no-suitable-cell-in-this-la
plmn-not-allowed
roaming-not-allowed-in-this-la
map-diag-info gprs-subscription-unknown gmm-cause-code gmm_cause
identifies a replacement
GMM cause code if additional ‘gprs-subscription-unknown’ diagnostic MAP failure information is received
when the UE’s access request is rejected due to map cause ‘unknown-subscriber’.
when the UE’s access request is rejected due to map cause ‘unknown-subscriber’.
map-diag-infoimsi-unknown gmm-cause-code gmm_cause
identifies a replacement GMM cause code if
additional ‘imsi-unknown’ diagnostic MAP failure information is received when the UE’s access request is
rejected due to map cause ‘unknown-subscriber’.
rejected due to map cause ‘unknown-subscriber’.
