16.3 Short message service cell broadcast
34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification
16.3.1 Definition
16.3.2 Conformance requirements
In idle mode, the UE has the ability to ignore repeated broadcasts of CBS messages already received (the message has not changed since it was last broadcast i.e. sequence number has not changed within the message’s indicated geographical area);
A UE supporting Cell Broadcast Service (CBS) shall be capable to receive BMC messages in the Idle mode.

– 3GPP TS 25.324 clause 11.
16.3.3 Test purpose
This test verifies that an UE supporting SMS-CB is able to receive SMS-CB messages and is able to ignore repeated broadcasts of CBS messages.
16.3.4 Method of test
Initial conditions
– System Simulator:
– 1 cell, default parameters;
– the SS provides a BCCH/CCCH to support the UE in idle mode;
– periodic location updating is disabled.
– User Equipment:
– the UE shall be in the idle updated state.

Support for short message transmission cell broadcast.
Test procedure
Three Cell Broadcast (CB) messages are sent by the SS on the CTCH with message codes 0,1,1 in serial number fields respectively.
NOTE: If the UE fails the test because of a failure to receive the message due to collision of CTCH and paging occasion, then the operator may re-run the test.
Expected sequence
Since the SMS-CB messages are sent continuously, a table is not applicable in this test.
