29.1203GPPMobile Application Part (MAP) specification for Gateway Location Register (GLR)Release 17TS

20.2.2.1 Subscriber deletion procedure

The subscriber deletion procedure in the GLR is described in the subclause 19.

20.2.2.2 Subscriber data modification procedure

When receiving either the MAP_INSERT_SUBSCRIBER_DATA indication or the MAP_DELETE_SUBSCRIBER_DATA indication, the GLR checks the parameters and data in the primitive. Data errors are reported as an unexpected data value error or a data missing error depending on the nature of the error.

After receiving the first MAP_INSERT_SUBSCRIBER_DATA indication, the GLR will check the IMSI that is included in the primitive. If the IMSI is unknown, the error "Unidentified subscriber" is returned.

If the GLR does not support received basic or supplementary services or the network feature Operator Determined Barring, or there is a problem with Regional Subscription Data then this is reported to the HLR.

If the entire MSC area that covered the VLR wherein the subscriber is registered is restricted due to regional subscription, this is reported to the HLR.

If the updating of the subscriber data is not possible, the GLR will initiate the MAP_U_ABORT request primitive.

If the updating is successful in the GLR, the GLR will initiate the MAP_INSERT_SUBSCRIBER_DATA request or the MAP_DELETE_SUBSCRIBER_DATA request to the VLR or to the SGSN wherein the subscriber is registered.

The subscriber data modification procedure in the GLR is shown in the figures 20.2.2.2/1, 20.2.2.2/2, 20.2.2.2/3, 20.2.2.2/4, 20.2.2.2/5 and 20.2.2.2/6.
