Reporting of General Error Situations: This function allows reporting of general error situations, for which function specific error messages have not been defined.
- 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.
- 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).
- 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.

- 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.

- 8.3.7 The Power Adjustment Type IE defines the characteristic of the power adjustment. If the value of the Power Adjustment Type IE is "Common", the Power Balancing Adjustment Type of the Node B Communication Context shall be set to "Common". As long as the Power Balancing Adjustment Type of the Node B Communication Context is set to "Common", the Node B shall perform the power adjustment (see below) for all existing and future radio links associated with the context identified by the Node B Communication Context ID IE and use a common DL reference power level. If the value of the Power Adjustment Type IE is "Individual", the Power Balancing Adjustment Type of the Node B Communication Context shall be set to "Individual". The Node B shall perform the power adjustment (see below) for all radio links addressed in the message using the given DL Reference Powers per RL. If the Power Balancing Adjustment Type of the Node B Communication Context was set to "Common" before this message was received, power balancing on all radio links not addressed by the DL POWER CONTROL REQUEST message shall remain to be executed in accordance with the existing power balancing parameters which are now considered RL individual parameters. Power balancing will not be started on future radio links without a specific request. If the value of the Power Adjustment Type IE is "None", the Power Balancing Adjustment Type of the Node B Communication Context shall be set to "None" and the Node B shall suspend on going power adjustments for all radio links for the Node B Communication Context. If the Inner Loop DL PC Status IE is present and set to "Active", the Node B shall activate inner loop DL power control for all radio links for the Node B Communication Context. If the Inner Loop DL PC Status IE is present and set to "Inactive", the Node B shall deactivate inner loop DL power control for all radio links for the Node B Communication Context according to ref. TS 25.214 [10].
- 8.3.8 The Dedicated Measurement Initiation procedure shall not be initiated if a Prepared Reconfiguration exists, as defined in subclause 3.1 except when the Node B Communication Context ID IE in the DEDICATED MEASUREMENT INITIATION REQUEST message is set to the reserved value "All NBCC". If the Node B Communication Context ID IE in the DEDICATED MEASUREMENT INITIATION REQUEST message is set to the reserved value "All NBCC", the Dedicated Measurement Initiation procedure may be initiated by the CRNC at any time when the Node B Communication Context exists.
