This message is used for handover from UMTS to another system e.g. GSM. One

or several messages from the othersystem can be included in the Inter-RAT

message information element in this message. These messages are structured

and coded according to that systems specification.

This message is sent on the RRC connection used before the Inter-RAT Handover was executed. The message

indicatesthat the UE has failed to seize the new

channel in the other system.

UE--BSC

UE--BSC

In case of the synchronized handover, the MS sends up to four HND_ACC

messages to the BTS when receiving the HND_CMD (this applies to intra-BSC as

well). The data of a HND_ACC message is only one byte long and carries the

handover reference, that is, the temporary identifier of the MS.If the assignment procedure is used for the

intra-BTS handover,then sending of the HND_ACC messages is not necessary.

The MS confirms handover by sending of HND_COM . Only now, the MSC receives

the informationin a HND_PERF message that a handover

was performed by the BSS.This message is sent on the main DCCH from the mobile station to the network

to indicate that the mobilestation has established the main

signalling link successfully.
