16.3a Short message service cell broadcast Discontinuous Reception (DRX)

34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification

16.3a.1 Definition

16.3a.2 Conformance requirements

A UE supporting Cell Broadcast Service (CBS) shall be capable to receive BMC messages in the Idle mode.

In idle mode, the UE will enter CBS DRX mode based upon received Schedule Messages.

References

– 3GPP TS 25.324 clause 9.1.

– 3GPP TS 23.041 clause 8.

16.3a.3 Test purpose

This test verifies that a UE supporting SMS-CB and SMS-CB DRX is able to receive SMS-CB messages in DRX..

16.3a.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;

– Cell Broadcast Service DRX is enabled.

– periodic location updating is disabled.

– User Equipment:

– the UE shall be in the idle updated state.

– the UE shall be configured, not to opt-out of presentation of Cell Broadcast messages with Message ID 4371 and 4379.

Figure 16.3a.4-1: CTCH Transmission pattern of the Schedule and Test messages

  1. The SS sends CELL BROADCAST SCHEDULE #1 message (1 CTCH-BS) on the CTCH.
  2. The SS waits for 6 CTCH-BS after Step a), then sends CELL BROADCAST TEST #1 message (3 CTCH-BS), followed by CELL BROADCAST SCHEDULE #2 message (1 CTCH-BS). (Note 1)
  3. The SS waits for 9 CTCH-BS after Step b), then sends CELL BROADCAST SCHEDULE#3 message (1 CTCH-BS), followed by CELL BROADCAST TEST #2 message (3 CTCH-BS). (Note 2)
  4. The SS waits for 10 CTCH-BS after Step c), then sends CELL BROADCAST TEST #3 message (3 CTCH-BS). (Note 3)

NOTE 1: CELL BROADCAST TEST#1 and CELL BROADCAST SCHEDULE #2 are situated at the beginning of the Scheduling period referred to by CELL BROADCAST SCHEDULE #1.

NOTE 2: CELL BROADCAST SCHEDULE #3 and CELL BROADCAST TEST#2 and are situated in the middle of the Scheduling period referred to by CELL BROADCAST SCHEDULE #2.

NOTE 3: CELL BROADCAST TEST#3 is situated at the end of the Scheduling period referred to by CELL BROADCAST SCHEDULE #3.

NOTE 4: 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.
