36.523-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core (EPC)Part 1: Protocol conformance specificationRelease 17TSUser Equipment (UE) conformance specification

The following general assumptions are used for the MBMS service continuity test cases:

– The MBMS service the UE is interested in receiving is active during the whole test execution.

– The test cases do not make any assumptions on which method is used by the UE under test to be configured with necessary USD information. For information about User Service Discovery/Announcement methods for MBMS services see [50] TS 26.346 subclause 5.2.

– To enable testing of the MBMS service continuity feature it is expected that a UE supporting MBMS service continuity; and the UE has received SIB15 indicating availability of a MBMS service on one or more frequencies; and the UE is interested in receiving or is receiving the MBMS service:

– when in IDLE mode under the conditions specified in the test cases: the UE prioritizes the frequencies providing the MBMS service and if the serving cell is not providing the MBMS service performs inter-frequency cell re-selection to a suitable neighbour cell of the prioritized frequency even if the serving cell is better;

– when in RRC connected mode under the conditions specified in the test cases: the UE initiates a MBMS interest indication procedure to indicate that the UE is interested in receiving the MBMS service on the frequency.
