In this clause, only TC protocol messages are described. TC control messages are intended to be sent using the RRC downlink and uplink direct transfer procedures, see TS 25.331 [5], subclause 8.1.9 and subclause 8.1.10.

NOTE 1: A message received with skip indicator different from 0 will be ignored.

NOTE 2: For general definition of Layer 3 message format see TS 24.007 [1], clause 11.

NOTE 3: GSM and 3G test messages uses the same protocol discriminator value ("1111"). Following message type value series are reserved for GSM testing commands as specified by TS 44.014 [13]:
0000xxxx, 0001xxxx and 0010xxxx where x represent 0 or 1. For 3G test commands the message type value series 0100xxxx is reserved.

6.1 Timer values

TT01:

– for testing the reception of MBMS services operating in MBSFN mode: [15] seconds.

– otherwise: 2.5 seconds.

NOTE: For testing the reception of MBMS services operating in MBSFN mode a longer time is specified for TT01 as the response to the CLOSE UE TEST LOOP message by the UE may involve waiting for cluster selection and/or MTCH establishment on the MBSFN carrier.

6.2 CLOSE UE TEST LOOP

This message is only sent in the direction SS to UE.

Q4..Q0 = RB identity number, 5..32 (binary coded, Q4 is most significant bit and Q0 least significant bit), where RB identity identifies the radio bearer, see [5] TS 25.331. The range is limited to 5..32 due to RB0 to RB4 are reserved for signalling radio bearers.

NOTE: The parameter UL RLC SDU size is only applicable for UE test loop mode 1 and for radio bearers not using the PDCP protocol layer, see subclause 5.3.2.6.2. The UE capability for support of UL RLC SDU sizes bigger than 12160 bits is stated by the UE manufacturer as an Implementation Conformations Statement (ICS) as defined in TS 34.123-2 [17], subclause A.4.3.1 table A.13. The UE Total RLC AM buffer size according to the UE Radio Access Capabilities defined in TS 25.306 [18] shall not be exceeded.
