Presentation Notes
Cell Configuration Management: This function gives the CRNC the possibility to manage the cell configuration information in a Node B. Common Transport Channel Management: This function gives the CRNC the possibility to manage configuration of Common Transport Channels in a Node B. System Information Management: This function gives the CRNC the ability to manage the scheduling of System Information to be broadcast in a cell. Resource Event Management: This function gives the Node B the ability to inform the CRNC about the status of Node B resources. Configuration Alignment: This function gives the CRNC and the Node B the possibility to verify and enforce that both nodes have the same information on the configuration of the radio resources. Measurements on Common Resources: This function allows the CRNC to initiate measurements on common resources in the Node B. The function also allows the Node B to report the result of the measurements. Radio Link Management: This function allows the CRNC to manage radio links using dedicated resources in a Node B. Radio Link Supervision: This function allows the CRNC to report failures and restorations of a Radio Link. Compressed Mode Control [FDD]: This function allows the CRNC to control the usage of compressed mode in a Node B. Measurements on Dedicated Resources: This function allows the CRNC to initiate measurements on dedicated resources in the Node B. The function also allows the Node B to report the result of the measurements. DL Power Drifting Correction [FDD]: This function allows the CRNC to adjust the DL power level of one or more Radio Links in order to avoid DL power drifting between the Radio Links. Reporting of General Error Situations: This function allows reporting of general error situations, for which function specific error messages have not been defined.

NBAP Procedures

Page 10: NodeB Application Part

NBAP ProceduresSome Useful Definitions

CRNC Communication Context–Contains necessary information for CRNC for communication with a

specific UE –CRNC Communication Context ID

Node B Communication Context–Contains necessary information for the Node B for communication with

a specific UE–Radio Link Setup and Radio Link Deletion Procedures–Node B Communication Context ID

Unless explicitly indicated in the procedure description, at any instance in time one protocol peer shall have a maximum of one ongoing dedicated NBAP procedure related to a certain Node B Communication Context

10March 13, 2013 Tusharadri Sarkar

Presenter
Presentation Notes
Node B Communication Context: The Node B Communication Context contains the necessary information for the Node B for communication with a specific UE. The Node B Communication Context is created by the Radio Link Setup procedure and deleted by the Radio Link Deletion procedure when deleting the last Radio Link within the Node B Communication Context. The Node B Communication Context is identified by the Node B Communication Context ID.
Page 11: NodeB Application Part

NBAP ProceduresSome Useful Definitions

All NBAP Elementary Procedures are divided into TWO Types–NBAP Common Procedures–NBAP Dedicated Procedures

Also, based on the response types, all Elementary Procedures are divided into TWO classes–Class 1 Elementary Procedures–Class 2 Elementary Procedures

Please refer to Section 8, Table 2 and Table 3 of 3GPP TS 25.433V11.3.0 (2012-12) for the comprehensive list of all Class 1 and Class 2 elementary procedures

11March 13, 2013 Tusharadri Sarkar

Presenter
Presentation Notes
NBAP common procedures are procedures that request initiation of a Node B Communication Context for a specific UE in Node B or are not related to a specific UE. NBAP common procedures also incorporate logical O&M (TS 25.401) procedures. NBAP dedicated procedures are procedures that are related to a specific Node B Communication Context in Node B. This Node B Communication Context is identified by a Node B Communication Context identity. Class 1 Elementary Procedures are procedures with a response (Success or Failure) Class 2 Elementary Procedures are procedures without a response (Assumed to be successful always).

Presentation Notes
Class 1: Where the logical error occurs in a request message of a class 1 procedure, and the procedure has a message to report this unsuccessful outcome, this message shall be sent with an appropriate cause value. Typical cause values are: -Protocol Causes: 1.Semantic Error 2.Message not compatible with receiver state Where the logical error is contained in a request message of a class 1 procedure, and the procedure does not have a message to report this unsuccessful outcome, the procedure shall be terminated and the ERROR INDICATION procedure shall be initiated with an appropriate cause value. The Procedure ID IE, the Triggering Message IE and the Transaction ID IE within the Criticality Diagnostics IE shall then be included in order to identify the message containing the logical error. Where the logical error exists in a response message of a class 1 procedure, the procedure shall be considered as unsuccessfully terminated and local error handling shall be initiated. Class 2: Where the logical error occurs in a message of a class 2 procedure, the procedure shall be terminated and the ERROR INDICATION procedure shall be initiated with an appropriate cause value. The Procedure ID IE, the Triggering Message IE and the Transaction ID IE within the Criticality Diagnostics IE shall then be included in order to identify the message containing the logical error.

8.2.17 If the RADIO LINK SETUP REQUEST message includes a DCH Information IE with multiple DCH Specific Info IEs, then the Node B shall treat the DCHs in the DCH Information IE as a set of co-ordinated DCHs. The Node B shall include these DCHs in the new configuration only if it can include all of them in the new configuration. If the DCH Specific Info IE includes the Unidirectional DCH Indicator IE set to "Uplink DCH only", the Node B shall ignore the Transport Format Set IE for the downlink for this DCH. As a consequence this DCH is not included as a part of the downlink CCTrCH. If the DCH Specific Info IE includes the Unidirectional DCH Indicator IE set to "Downlink DCH only", the Node B shall ignore the Transport Format Set IE for the uplink for this DCH. As a consequence this DCH is not included as a part of the uplink CCTrCH. Response Message: If the RLs are successfully established, the Node B shall and respond with a RADIO LINK SETUP RESPONSE message. After sending the RADIO LINK SETUP RESPONSE message the Node B shall continuously attempt to obtain UL synchronization on the Uu interface. For each RL for which the Delayed Activation IE is not included in the RADIO LINK SETUP REQUEST message, the Node B shall: -[FDD - start transmission on the DL DPDCH(s) of the new RL as specified in TS 25.427 [16].] -[TDD - start transmission on the new RL immediately as specified in TS 25.427 [16].] For each RL for which the Delayed Activation IE is included in the RADIO LINK SETUP REQUEST message, the Node B shall: -if the Delayed Activation IE indicates "Separate Indication": -not start any DL transmission for the concerned RL on the Uu interface; -if the Delayed Activation IE indicates "CFN": -[FDD - start transmission on the DL DPDCH(s) of the new RL as specified in TS 25.427 [16], however never before the CFN indicated in the Activation CFN IE.] -[TDD - start transmission on the new RL at the CFN indicated in the Activation CFN IE as specified in TS 25.427 [16].]

Quiz

Is the Dedicated Radio Link Setup a NBAP Common procedure or a NBAP Dedicated procedure?

70

Note: There is a Common NBAP Channel as well as a Dedicated NBAP Channel

March 13, 2013 Tusharadri Sarkar

Presenter
Presentation Notes
On the Iub interface, establishment of the first dedicated RL is considered as a NBAP common procedure i.e. all the signaling messages are exchanged via the Node B Control Ports. After the first RL is established the Node B will have a ‘Node B Communication Context’ for the UE identified by the ‘Node B Communication Context ID’. So, further procedures related to that UE will be part of NBAP dedicated procedures i.e. all the signaling messages are exchanged via the Node B Communication Control Ports.
