2 Cell Reconfiguration Procedure
About This Chapter
The cell reconfiguration procedure is performed to reconfigure a cell in the NodeB. This chapterdescribes the cell reconfiguration procedure in terms of protocols, triggering conditions,signaling procedure, and signaling tracing on the RNC LMT.
2.1 Protocols Related to Cell ReconfigurationThe cell reconfiguration procedure complies with a 3GPP TS25 protocol.
2.2 Triggering Conditions of Cell ReconfigurationCell reconfiguration is triggered when the parameters of the cell in the NodeB are modified onthe RNC LMT.
2.3 Signaling Procedure of Cell ReconfigurationThis part describes the signaling procedure of cell reconfiguration.
2.4 Using the RNC LMT to Tracing the Cell Reconfiguration ProcedureThe signaling tracing function of the RNC LMT can be used to trace the signaling of cellreconfiguration.

2.1 Protocols Related to Cell ReconfigurationThe cell reconfiguration procedure complies with a 3GPP TS25 protocol.
The compliance protocol is the 3GPP TS25.433 "UTRAN Iub interface Node B ApplicationPart (NBAP) signaling".
2.2 Triggering Conditions of Cell ReconfigurationCell reconfiguration is triggered when the parameters of the cell in the NodeB are modified onthe RNC LMT.
To modify parameters of the cell in the NodeB, run the MOD CELL command online on theRNC LMT.
2.3 Signaling Procedure of Cell ReconfigurationThis part describes the signaling procedure of cell reconfiguration.
Figure 2-1 shows the cell reconfiguration procedure.
Figure 2-1 Cell reconfiguration procedure
The procedure shown in Figure 2-1 is described as follows:
1. The CRNC sends a CELL RECONFIGURATION REQUEST message to the NodeBthrough the NCP. The NodeB then reconfigures the cell according to the parameters givenin the message.
2. The NodeB sends a response message to the CRNC through the NCP.
l If the cell is reconfigured, the NodeB sends a CELL RECONFIGURATIONRESPONSE message.

l If the cell fails to be reconfigured, the NodeB sends a CELL RECONFIGURATIONFAILURE message.
2.4 Using the RNC LMT to Tracing the Cell ReconfigurationProcedure
The signaling tracing function of the RNC LMT can be used to trace the signaling of cellreconfiguration.
Prerequisitel The RNC LMT works properly.
l You have logged in to the RNC with an account authorized to perform tracing management.
ContextTable 2-1 lists the messages to be traced.
