Step 1 Create an Iub tracing task by referring to Creating an RNC Tracing Task.

Figure 1-2 shows an example of Iub signaling tracing result.

Figure 1-2 Example of Iub signaling tracing result

In practice, the messages transmitted during cell setup depend on the configured data. In this

example, an HSDPA cell is set up. During the cell setup, the common transport channel setup

procedure is performed to set up a Secondary Common Control Physical Channel (S-CCPCH),

a Physical Random Access Channel (PRACH), a Paging Indicator Channel (PICH), and an

Acquisition Indicator Channel (AICH). The S-CCPCH carries two Forward Access Channels

(FACHs) and a Paging Channel (PCH). The PRACH carries a Random Access Channel (RACH).

Step 2 Create a Q.AAL2 tracing task by referring to Creating an RNC Tracing Task.

1.5 Elementary Procedures of Cell Setup

This describes the elementary procedures of cell setup in terms of triggering conditions and

signaling procedures in normal and abnormal conditions.

1.5.1 Resource Status Indication Procedure

The NodeB performs the resource status indication procedure to report its physical resources to

the Control RNC (CRNC).

1.5.2 Resource Audit Procedure

The CRNC performs the resource audit procedure to audit the configuration and status of the

logical resources in the NodeB. The audit may let the CRNC know the logical resources of the

NodeB and re-synchronize its resources with those of the NodeB.

1.5.3 Cell Setup Procedure

The cell setup procedure is performed to set up a cell in the NodeB.

1.5.4 Common Transport Channel Setup Procedure

The common transport channel setup procedure is performed to establish the necessary resources

in the NodeB, regarding the following channels: S-CCPCH, PICH, PRACH, AICH, FACH,

PCH, and RACH.

1.5.5 Iub User Plane Setup Procedure

The Iub userplane setup procedure is performed to set up bearers for data transmission on the

Iub interface.

1.5.6 System Information Update Procedure

The system information update procedure is performed for the NodeB to schedule and update

the system information segments, which are broadcast on the Broadcast Control Channel(BCCH), according to the parameters in the SYSTEM INFORMATION UPDATE REQUEST

message.

1.5.7 Physical Shared Channel Reconfiguration Procedure

The physical shared channel reconfiguration procedure is performed for the NodeB to

reconfigure the physical channels according to the PHYSICAL SHARED CHANNEL

RECONFIGURATION REQUEST message sent from the CRNC.

1.5.8 Common Measurement Initiation Procedure

The common measurement initiation procedure is performed for the CRNC to request the

initiation of measurements on common resources in a NodeB. The NodeB then initiates the

requested measurements according to the parameters given in the COMMONMEASUREMENT INITIATION REQUEST message sent from the CRNC.

1.5.1 Resource Status Indication Procedure

The NodeB performs the resource status indication procedure to report its physical resources to

the Control RNC (CRNC).

Triggering Conditions

The NodeB triggers the procedure in one of the following conditions:

l A local cell is added to the NodeB.

l A local cell is deleted from the NodeB.

l The capabilities of a local cell change at the NodeB.

l A cell changes its capability or resource operational state or both capability and resource

operational state at the NodeB.

l Common physical channels or common transport channels or both common physical

channels and common transport channels change their capabilities at the NodeB.l A Communication Control Port (CCP) changes its resource operational state at the NodeB.

l A local cell group changes its resource capability at the NodeB.

Procedure

Figure 1-4 shows the resource status indication procedure.

Figure 1-4 Resource status indication procedure

The NodeB sends a RESOURCE STATUS INDICATION message to the CRNC through the

NodeB Control Port (NCP). This message contains the triggering condition and the associated

logical resource information.

1.5.2 Resource Audit Procedure

The CRNC performs the resource audit procedure to audit the configuration and status of the

logical resources in the NodeB. The audit may let the CRNC know the logical resources of theNodeB and re-synchronize its resources with those of the NodeB.

RAN

Triggering Conditions

The CRNC receives a RESOURCE STATUS INDICATION message from the NodeB.

ProcedureFigure 1-5 shows the resource audit procedure.

Figure 1-5 Resource audit procedure

The procedure shown in Figure 1-5 is described as follows:

1. The CRNC sends an AUDIT REQUEST message to the NodeB through the NCP to initiate

the resource audit procedure.

2. The NodeB sends a response message to the CRNC through the NCP.

l If the audit is successful, theNodeB sends an AUDIT RESPONSE message.

The AUDIT RESPONSE message contains information about common physical

channels of the logical cell, CCP, local cell, and local cell group. The information about

local cell and local cell group is the abstraction of the physical resources of the NodeB.

In this way, the CRNC can allocate the logical resources of the cell according to the
