Activating a Pool Spanning Network

The following example explains the procedure to activate a pool spanning network.

Note:

Once the Pool Spanning is activated, it cannot be deactivated.

In this example, UDR1 hosts all of the subscribers and pools for IMSI range 1 to 6. UDR2 is newly installed UDR which is going to host IMSI range 4 to 6 in the distributed pool network and UDR1 is going to host IMSI range 1 to 3 after the migration. UDR2 has to be configured to be the primary data source for MPE2 which at the start of the migration hosts the sessions for subscribers with IMSI range 4 to 6.

At the start of the migration, the distributed pool network is fully configured and enabled with active ComAgent connections between UDR1 and UDR2.

To activate a pool span network:

1. Upgrade UDR1 and UDR2 to the release 12.2.
2. Configure ComAgent on UDR1 and UDR2. See, Configuring ComAgent for UDR Machines.
3. Configure Pool Network Table on UDR1 and UDR2. See, Configuring Pool Network.
4. Add entries in the UDR Key Range table on UDR1 and UDR2 for the pool ID ranges. See, Inserting UDR for Pool Network.
5. Set Pool Spanning Feature to enabled.
   Signaling starts looking for Pool Spanning Pool members and Provisioning starts checking UDR Key Range table.
6. Disable provisioning for during pool migration phase.
7. Run the following command to migrate pooled subscribers in IMSI range:udr1# o2omt –imsi 4-6 –pso
8. Enable/Configure migration on demand on UDR2 for subscriber phase.
9. Enable provisioning on both systems.
10. Run the following command to use o2omt to migrate non-pooled subscribers in IMSI range.udr1# o2omt –imsi 4-6
11. Disable migration on demand.
