23、the present document, the terms and definitions given in TR21.9055. A term defined in the present document takes precedence over the definition of the same term, if any, in TR21.9055.UE-associated Signalling Connection: UE-associated Signalling Connection is a logical connection between HNB and HNB-
24、GW associated to an Iu signalling connection for a particular UE over the single signalling connection between the HNB and HNB-GW, identified by the identities Context ID and CN Domain ID. 3.2AbbreviationsFor the purposes of the present document, the following abbreviations apply:CNCore NetworkEPEle
25、mentary ProcedureHNBHome Node BHNB-GWHome Node B GatewayPDUProtocol Data UnitRUARANAP User AdaptionSCTPStream Control Transmission Protocol4GeneralThe protocol described in the present document is the protocol between HNB-GW and HNB.4.1Procedure specification principlesThe principle for specifying t
26、he procedure logic is to specify the functional behaviour of the HNB & HNB-GW exactly and completely.The following specification principles have been applied for the procedure text in clause 8:-The procedure text discriminates between:1)Functionality which shall be executed:-The procedure text indic
27、ates that the receiving node shall perform a certain function Y under a certain condition. If the receiving node supports procedure X but cannot perform functionality Y requested in the REQUEST message of a Class 1 EP, the receiving node shall respond with the message used to report unsuccessful out
28、come for this procedure, containing an appropriate cause value.2)Functionality which shall, if supported be executed:-The procedure text indicates that the receiving node shall, if supported, perform a certain function Y under a certain condition. If the receiving node supports procedure X, but does
29、 not support functionality Y, the receiving node shall proceed with the execution of the EP, possibly informing the requesting node about the not supported functionality.-Any required inclusion of an optional IE in a response message is explicitly indicated in the procedure text. If the procedure te
30、xt does not explicitly indicate that an optional IE shall be included in a response message, the optional IE shall not be included.4.2Forwards and backwards compatibilityThe forwards and backwards compatibility of the protocol is assured by mechanism where all current and future messages, and IEs or
31、 groups of related IEs, include Id and criticality fields that are coded in a standard format that will not be changed in the future. These parts can always be decoded regardless of the standard version.4.3Specification notationsFor the purposes of the present document, the following notations apply
32、:ProcedureWhen referring to an elementary procedure in the specification the Procedure Name is written with the first letters in each word in upper case characters followed by the word procedure, e.g. HNB Registration procedure.MessageWhen referring to a message in the specification the MESSAGE NAME
33、 is written with all letters in upper case characters followed by the word message, e.g. CONNECT message.IEWhen referring to an information element (IE) in the specification the Information Element Name is written with the first letters in each word in upper case characters and all letters in Italic
34、 font followed by the abbreviation IE, e.g. HNB Identity IE.Value of an IEWhen referring to the value of an information element (IE) in the specification the Value is written as it is specified in subclause 9.2 enclosed by quotation marks, e.g. Abstract Syntax Error (Reject) or Background .5RUA serv

36、 (IETF RFC 4960 9)7Functions of RUAThe RUA has the following functions:-Transparent transfer of RANAP messages-Error Handling. This function allows the reporting of general error situations, for which function specific error messages have not been defined.These functions are implemented by one or se

38、Error IndicationERROR INDICATION8.2Connect8.2.1GeneralThe HNB or HNB-GW can initiate this procedure to establish an UE-associated Signalling Connection and carry a RANAP message.8.2.2Successful Operation8.2.2.1HNB OriginatedFigure 1: Connect to HNB-GW procedureThis procedure is used to carry the fir
39、st RANAP message from the HNB to the HNB-GW. 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 establishment of a new UE-associated Signalling Connection between HNB and HNB-GW, which is directly map
40、ped to the Iu Signalling Connection the RANAP message refers to. NOTE:The Context ID is used as the Iu Signalling Connection identifier in the corresponding RANAP messages. 8.2.2.2HNB-GW OriginatedFigure 1A: Connect to HNB procedureThis procedure is used to carry the first RANAP message from the HNB
41、-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 will allocate the context id. If
42、 the 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
43、handling the RANAP message.8.3Direct Transfer8.3.1GeneralThis procedure is initiated by either the HNB or HNB-GW to transport a RANAP message between the two nodes. The HNB-GW can initiate this procedure to establish an UE-associated Signalling Connection when carrying the second RANAP RELOCATION RE
44、QUEST message.8.3.2Successful Operation (HNB-GW Originated)Figure 2: Direct Transfer to HNBThis procedure is used to carry any DL connection-oriented RANAP message defined in TS 25.413 2 from the HNB-GW to the HNB. This procedure can be used to carry the second RANAP RELOCATION REQUEST message from
45、the HNB-GW to an HNB for a particular UE. This shall trigger the establishment of a second UE-associated Signalling Connection between HNB-GW and HNB, which is directly mapped to the Iu Signalling Connection the RANAP message refers to.8.3.3Successful Operation (HNB Originated)Figure 3: Direct Trans
46、fer to HNB-GWThis procedure is used to carry any UL connection-oriented RANAP message defined in TS 25.413 2, except those carried in CONNECT or DISCONNECT messages, from the HNB to the HNB-GW. 8.3.4Abnormal Conditions-8.4Disconnect8.4.1GeneralThis procedure is initiated by either the HNB or the HNB
