This message is sent on DBPSCH on either PACCH, FACCH or SDCCH and optionally on SACCH by the mobile station to the network during a handover procedure. It shall not be sent on the 52-multiframe structure (SBPSCH). This message is formatted as four identical access bursts on PACCH, FACCH and SDCCH, and as one individual access burst on SACCH. Each access burst shall use the 8-bit access burst format and follow the 8-bit PRACH uplink/PACCH uplink short acknowledgement block format defined in 3GPP TS 44.004. Each access burst is coded as shown in table 11.2.33.1. The order of bit transmission is defined in 3GPP TS 44.004. The numbering, assembling and field mapping conventions defined for RLC/MAC control blocks in sub-clause 10.0b shall apply.
