17.1.2 Subscriber Data Management Co-ordinator for the VLR<br />

Page 377<br />

<strong>GSM</strong> <strong>09.02</strong> <strong>Version</strong> <strong>5.3.0</strong>: August 1996<br />

The MAP_OPEN indication opens the dialogue for the stand-alone subscriber data management procedure<br />

when the application context subscriberDataManagementContex is received. If that service is successful,<br />

the Co-ordinator can receive the firs service primitive from the MAP_PM. Depending on the received<br />

primitive, the user process is created as follows:<br />

- if the MAP_INSERT_SUBSCRIBER_DATA indication is received, the process<br />

INS_SUBS_DATA_VLR is created;<br />

- if the MAP_DELETE_SUBSCRIBER_DATA indication is received, the process<br />

Delete_Subscriber_Data_VLR is created.<br />

After creation of the user process the Co-ordinator relays the messages between the MAP_PM and the<br />

invoked process until a request or an indication for dialogue termination is received.<br />

The Subscriber_Data_Management Co-ordinator is shown in the figure 17.1/2.
