In order to maintain TrFO connection in SRNS Relocation, procedures specified in 3GPP TS 23.205 [8] and 3GPP TS 23.009 [11] for "Intra-MSC SRNS Relocation" or "Inter-MSC SRNS Relocation" shall be followed. Note that the "Intra-MSC SRNS Relocation" procedure can also be used for relocation between RNCs connected to different 3G MSCs (see 3GPP TS 23.009 [11], clause 1, "Flexible Iu interface for handover/relocation" option and "Intra domain connection of RAN nodes to multiple CN nodes" option).
