The SRNS Relocation Info information element includes the SRNS RELOCATION INFO message defined in TS 25.331 [40]. This IE shall be included if the target radio access technology is UTRAN. The content is the same as the SRNS RELOCATION INFO message content sent by the GANC to the target RNC in the Source RNC to Target RNC Transparent Container. Note that the type of this IE is the same as the UTRAN RRC Message defined in sub-clause 11.2.111, with the exception that the IEI is 2-octets in length.

10.3.23 GA-RRC RELOCATION ACCESS

The MS sends this message to the GANC to indicate that the MS has been commanded to handover a CS domain session to GAN Iu mode but the GA-RRC CS domain sub-layer entity in the MS is not yet in the GA-RRC CONNECTED state.

10.3.23.1 UTRAN RRC Message

This information element contains the entire UTRAN RRC handover message received via the source radio access technology. If the source radio access technology is GERAN, the value part of the UTRAN RRC Message IE is coded as the HANDOVER TO UTRAN COMMAND message specified in [40]. If the source RAT is UTRAN, the value part of the UTRAN RRC Message IE is coded as the UTRAN reconfiguration message received from the target RNS as specified in [40]; e.g., PHYSICAL CHANNEL RECONFIGURATION.

10.3.24 GA-RRC RELOCATION COMPLETE

The MS sends this message to the GANC to indicate that the handover to GAN Iu mode is complete.
