Statistics Items

Criteria for Creating Formulas

The formulas described in this manual are described based on statistics values

which are cumulated hourly, daily and monthly. Statistics values which are used

as criteria for unit of collection are obtained by deleting sum() from the formula.

System Configuration Criteria

This manual is based on Macro configuration. For Pico configuration, some of the

index ranges are as follows.

- cNum: 0~0

- ShelfId: 0~0

- PortNum: 0~3

- SlotId: 0~0

Step Description

1) The UE performs the Random Access procedure with the eNB.

2)-4) The UE transmits the NAS SERVICE REQUEST message to the MME. The SERVICE

REQUEST message is encapsulated in an RRC message transmitted to the eNB.

5) The eNB transmits the SERVICE REQUEST message to the MME. The SERVICE

REQUEST is encapsulated in an S1-AP INITIAL UE message.

6) If there is no UE context for the UE in the network, the integrity is not protected for the

ATTACH REQUEST message, or the integrity check fails, an authentication and an NAS

security setup are always performed. The UE performs the EPS AKA procedure (TS

33.401, 6.1.1) with the MME. The MME sets up an NAS security association with the UE

using the NAS SMC procedure (TS 33.401, 7.2.4.4).

7) The MME transmits the S1-AP Initial Context Setup Request message to the eNB.

This step activates both the radio bearer and S1 bearer for all active EPS bearers.

8)-11) The eNB sets up the RRC radio bearers. The user plane security is set up at this step.

The uplink data from the UE can be sent to the S-GW by the S-GW.

The eNB transmits the uplink data to the S-GW, and then the S-GW transmits it to the P-

GW.

12) The eNB transmits the S1-AP Initial Context Setup Request message to the MME.

13)-14) The MME transmits the Modify Bearer Request message for each PDN connection to

the S-GW.

Now, the S-GW can transmit the downlink data to the UE. The S-GW transmits the

Modify Bearer Response message to the MME.

Figure 2. Collection Time for RRC Connection Establishment

For statistics on RRC connection establishment, Attempt, Success, Fail and Reject statistics are counted. Attempt statistic is counted when the RRC

Connection Request message is received. Success statistic is counted when the messages up to RRC Connection Setup Complete are successfully

received.

When a timeout or internal failure occurs during the procedure from 1 to 2 in the figure above, it is counted as Fail, returning the cause value.

Reject statistic is counted when the eNB determines that the call cannot be accepted after receiving the RRC Connection Request message, and the

applicable cause value is recorded.

3.2 RRC Connection Reconfiguration

This section provides statistics for RRC Connection Reconfiguration.

There is no Fail statistic as the RRC Connection Reconfiguration message is transmitted down from the source and the RRC Connection

Reconfiguration Complete message is transmitted to the target. In this case, the attempt and success counts in the reconfiguration statistics for the

system can be different.

The transmission of the RRC Connection Reconfiguration to the UE is counted as Attempt, while the receipt of RRC Connection Reconfiguration

Complete from the UE is counted as Success. Upon handover, the source eNB transmits RRC Connection Reconfiguration (handover command) to

the UE; the UE transmits RRC Connection Reconfiguration Complete (handover command complete) to the target eNB. Therefore, a fail count is

not returned because it is not possible to determine transmission failure.

When RRC Connection Re-establishment Request is received, it is counted as an attempt; if the call context exists in the eNB and the security key

value uploaded by the UE matches, RRC Connection Re-establishment is transmitted to the UE; and when RRC Connection Re-establishment

Complete is received, it is counted as Success. If a call text does not exist in the eNB or the security key value uploaded by the UE does not match,

RRC Connection Re-establishment Reject is transmitted to the UE, and it is counted as Reject. Then, if RRC Connection Re-establishment

Complete is not received, the call is released.

3.4 RRC Connection Release

This section provides statistics for RRC Connection Release.

MME-initiated RRC connection release: The MME transmits the UE context release command to eNB to release the UE-associated logical

connection. Then, the eNB transmits the RRC connection release to the UE, releases the eNB resource, and transmits the UE context release

complete to the MME to complete the call release procedure. An MME-initiated call release occurs in the following cases.

Case Number Description

1 A procedure between UE and MME is completed (e.g. Detach).

2 A call in the source eNB is released due to successful handover.

3 A call in the target eNB is released due to cancelled handover.

4 The old logical connection is to be released when 2 logical connections are established for a specific UE (e.g. when UE duplication occurs in

the MME).

5 The UE is not a CSG member of the CSL cell.

eNB-initiated RRC connection release: If the eNB MAC scheduler determines that the UE has no traffic for the specific period of time, it transmits

the UE context release request to the MME, and then the call release procedure is completed by an MME-initiated RRC connection release

procedure. A call may be released by transmitting the UE context release request to the MME upon eNB failure or call setup failure.

An eNB-initiated call release occurs in the following cases.

Case Number Description

1 A call is released by user inactivity.

2 A call is released by eNB Radio Link Fail (RLF).

3 A call is released by MAX retransmission at the RCL end.
