Additional information is provided to enable the HNB-GW to handle the RANAP message without it being necessary to inspect the contents and trigger the

40、 establishment of a new UE-associated Signalling Connection between HNB and HNB-GW, which is directly mapped to the Iu Signalling Connection the RANAP message refers to. If HNB receives the Intra Domain NAS Node Selector IE in the RRC message, the HNB shall, if supported, include the Intra Domain NA

41、S Node Selector IE in the CONNECT message. NOTE: The Context ID is used as the Iu Signalling Connection identifier in the corresponding RANAP messages. 8.2.2.2 HNB-GW Originated HNB-GW CONNECT HNB Figure 1A: Connect to HNB procedure This procedure is used to carry the first RANAP message from the HN

42、B-GW to an HNB for a particular UE, e.g. RANAP RELOCATION REQUEST. This shall trigger the establishment of a new UE-associated Signalling Connection between HNB-GW and HNB, which is directly mapped to the Iu Signalling Connection the RANAP message refers to. The HNB-GW allocates the context id. If t

43、he first RANAP message received by the HNB GW is a RELOCATION REQUEST message and the RELOCATION REQUEST does not contain the CSG ID of the target cell the RUA CONNECT message may contain the CSG Membership Status IE. Additional information is provided by the HNB-GW to the HNB to assist the HNB in h
