We are facing following handover problem when A5/3 was activated in test scenario.
We have NSN core, Motorola BSS & NSN BSS
Source Cell—-Target Cell—- Result
Moto BTS (A5/3 enable)—-Nokia BTS (A5/3 disable)—-HO failure.
Moto BTS (A5/3 disable)—–Nokia BTS (A5/3 disable)—–HO success.
Nokia BTS (A5/3 disable)—–Moto BTS (A5/3 enable)—-HO Success.
Nokia BTS (A5/3 disable)—-Moto BTS (A5/3 disable)—–Success.
What could be the reason for the HO failure in the first scenario.
Thanks & regards,
