20.2.1.1 Procedures in the HLR

A subscriber tracing activation request from the OMC starts the appropriate process in the HLR: ATM_With_VLR_HLR if tracing is required in the MSC/VLR, ATM_With_SGSN_HLR if tracing is required in the SGSN.

The process in the HLR to activate tracing in the VLR is shown in figure 20.2/8. The MAP process invokes macros not defined in this clause; the definitions of these macros can be found as follows:

Receive_Open_Cnf see clause 25.1.2;

Check_Confirmation see clause 25.2.2.

Sheet 1: If the Repeat attempt counter has reached its limit, the test "Repeat Attempt" takes the "No" exit; otherwise the test takes the "Yes" exit. The number of repeat attempts and the interval between successive repeat attempts are operator options.

The process in the HLR to activate tracing in the SGSN is shown in figure 20.2/9. The MAP process invokes macros not defined in this clause; the definitions of these macros can be found as follows:

Receive_Open_Cnf see clause 25.1.2;

Check_Confirmation see clause 25.2.2.

Sheet 1: If the Repeat attempt counter has reached its limit, the test "Repeat Attempt" takes the "No" exit; otherwise the test takes the "Yes" exit. The number of repeat attempts and the interval between successive repeat attempts are operator options.

20.2.1.2 Procedure in the VLR

The process in the VLR to activate tracing in a stand-alone dialogue is shown in figure 20.2/10. The MAP process invokes a macro not defined in this clause; the definition of this macro can be found as follows:

Check_Indication see clause 25.2.1.

20.2.1.3 Procedure in the SGSN

The process in the SGSN to activate tracing in a stand-alone dialogue is shown in figure 20.2/11. The MAP process invokes a macro not defined in this clause; the definition of this macro can be found as follows:
