21.4.2 Process in the GLR for Status Reporting

The MAP process in the GLR to send the status report to the HLR is shown in figures 21.4.1/1 and 21.4.2/2.

Send Status report

When receiving the MAP_STATUS_REPORT indication, the MAP user in the GLR transfers the information to the HLR in the MAP_ STATUS_REPORT request.

The GLR then awaits the receipt of the MAP_ STATUS_REPORT confirm from the HLR. The MAP user in the GLR shall transfer the information contained in this primitive to the VLR in the MAP_ STATUS_REPORT response without checking its contents.
