We are implementing a CBC - Cell Broadcasting solution on our network.
But facing a weird issue…
This is the scenario:
CORE (of the entire network) = Huawei
RAN → Ericsson (50%) + Huawei (50%)
We managed to send the message on SIB11. But SIB11(ETWS) is Japanese standard
And we need American standard SIB12 (CMAS).
But we can’t get the Cellbroadcast message (info) to be sent.
- Core Huawei - RAN Huawei → OK, working
- Core Huawei - RAN Ericsson → NOT OK, Not working
Is there any advanced optimization that allows information (SIB12) to reach RAN Ericsson users?
- SIB11 only work in Ericsson RAN if we disable “Concurrent Warning Mesage indicator” in CBC platform
- SIB12 - never work, and we need to be (CMAS)
