22.4.3 Procedure in the VLR
29.0023GPPMobile Application Part (MAP) specificationRelease 17TS
The MAP process invokes macros not defined in this clause; the definitions of these macros can be found as follows:
Receive_Open_Ind see clause 25.1.1;
Receive_Open_Cnf see clause 25.1.2;
Check_Confirmation see clause 25.2.2;
Process_Access_Request_VLR see clause 25.4.2.
The MAP process in the VLR transfers the information received in the MAP_ACTIVATE_SS indication to the HLR in the MAP_ACTIVATE_SS request without checking the contents. The MAP_OPEN request includes the IMSI of the subscriber as the destination reference and the VLR number as the originating reference.
If the MAP_REGISTER_SS confirm is properly formed and contains a result or a user error, the MAP process in the VLR shall transfer the information contained in this primitive to the MSC in the MAP_ACTIVATE_SS response.
For call independent SS operations, each message shall contain only a single component. Messages which contain more than one component will be stopped at the air interface (as specified in 3GPP TS 29.011 [59]).
The activation process in the VLR is shown in figure 22.4.3/1.
