19.1.4 Procedures in the HLR<br />

The procedure in the HLR is initiated when it receives a MAP_REGISTER_SS indication.<br />

The HLR acts as follows:<br />

- if the operator has barred the subscriber from access to supplementary services, the Call Barred<br />

error should be returned to the VLR. The parameter "operatorBarring" shall be included with the<br />

error.<br />

The supplementary service request shall then be processed according to TS <strong>GSM</strong> 03.11 and the 03.8x<br />

and 03.9x-series of technical specifications. This handling may lead to either a successful result, a partially<br />

successful result, or an error being returned.<br />

For call independent SS operations, each message shall only contain a single component. Messages which<br />

contain more than one component will be stopped at the air interface (as specified in TS <strong>GSM</strong> 09.11):<br />

- if the VLR is to be updated after the supplementary service registration, the<br />

MAP_INSERT_SUBS_DATA_HLR process shall be initiated;<br />

- if at any time during this procedure a MAP_P_ABORT, MAP_U_ABORT or MAP_CLOSE indication<br />

concerning the process is received from the VLR, the process is terminated. If a MAP_NOTICE<br />

indication is received, a MAP_CLOSE request indicating sent towards the VLR.<br />

The registration procedure in the HLR is shown in figure 19.1.4/1.
