This message is sent by the mobile station to the network to make the network aware that the mobile station has left the old cell and arrived in the new cell. The message is sent four times using either the 8-bit or 11-bit access burst format on the PACCH associated with an uplink TBF allocated in the PS Handover Command message as described in sub-clause 8.10.4. The mobile station shall use the format indicated by the System Information parameter ACCESS_BURST_TYPE applicable to the target cell. Each message is coded as shown in table 11.2.42.1. 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.
