22.4 Activation procedure

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

22.4.1 General

The activation procedure is used to activate a supplementary service in the HLR. The activation procedure is a fully transparent communication between the MS and the HLR.

22.4.2 Procedures in the GLR

Supplementary service activation

When receiving the MAP_ACTIVATE_SS indication, the MAP user in the GLR transfers the information to the HLR in the MAP_ACTIVATE_SS request without checking the contents of the service indication.

The GLR may then receive the MAP_GET_PASSWORD indication. This information is transferred to the VLR in the MAP_GET_PASSWORD request. If a MAP_GET_PASSWORD confirm primitive is received from the VLR, the VLR initiates the MAP_GET_PASSWORD response towards the HLR.

The GLR will receive the MAP_ACTIVATE_SS confirm from the HLR. The MAP user in the GLR shall transfer the information contained in this primitive to the VLR in the MAP_ACTIVATE_SS response without checking its contents.

Error handling

The handling of MAP_P_ABORT, MAP_U_ABORT, MAP_NOTICE and unexpected MAP_CLOSE in this procedure is identical to the handling in the Registration procedure in the GLR, see subclause 22.2 of the present document.

The activation procedure in the GLR is shown in figure 22.4/1.
