TD-LTE网络性能 KPI(切换成功率)优化手册

1 切换成功率定义说明

1.1 指标公式

指标名称 集团规范公式 (eNB间 S1切换出成功次数 + eNB间 NSN 映射公式 X2 切换出成功次数 + eNB 内切换出100* sum(M8009C7 + M8014C7 + 切换成功率 成 功次数) /(eNB 间 S1切换出请+ eNB 内切换出请求次数) *100%

M8014C19) / sum(M8009C6 + M8014C0 + 求次 数+ eNB间 X2切换出请求次数 M8014C14) 1.2 COUNTER定义 1.2.1

集团规范定义

1、eNB 间 S1 切换出请求次数:

源 eNB 向 MME 发送的“切换请求”消息( HANDOVER REQUIRED)( 3GPP TS ),指示

eNB 间通过 S1 接口的切换出准备请求。向不同小区发送的同一切换准备请求,需要重

复统 计。

2、eNB 间 S1 切换出成功次数:

源 eNB收到 MME 发送的“UE上下文释放命令” 消息(UE CONTEXT RELEASE COMMAN)D (3GPP TS ),指示 eNB 间通过 S1接口的切换出执行成功。

3、 eNB 间 X2 切换出请求次数:

源 eNB向目标 eNB发送的“切换请求”消息( HANDOVER REQUES)T(3GPP TS ),指示

eNB间通过 X2 接口的切换出准备请求。向不同小区发送的同一切换准备请求,重复统

计。

4、 eNB 间 X2 切换出成功次数:

源 eNB收到目标 eNB发送的“ UE上下文释放” 消息(UE CONTEXT RELEA)S(E3GPP

TS ), 指示 eNB 间通过 X2接口的切换出执行成功。

5、 eNB 内切换出请求次数:

eNB 向 UE 发 送 携 带 mobilityControlInfo 的 “ RRC 连 接 重 配 置 ” 消 息

( RRCConnectionReconfiguration ),指示 eNB 内小区间切换出请求。 ( 3GPP TS )

6、 eNB 内切换出成功次数:

eNB 收 到 UE 发 送 的 “ RRC 连 接 重 配 置 完 成 ” 消 息

RRCConnectionReconfigurationComplete ),指示 eNB 内小区间切换出成功。 (3GPP

TS ) 1.2.2 NSN 映射

1、eNB 间 S1 切换出请求次数:

M8014C14 : INTER_ENB_S1_HO_PRE,P The number of Inter eNB S1-based Handover preparations ;

2、eNB 间 S1 切换出成功次数:

M8014C19 : INTER_ENB_S1_HO_SUC,C The number of successful Inter eNB S1-based Handover completions ;

3、 eNB 间 X2 切换出请求次数:

M8014C0 : INTER_ENB_HO_PREP, The number of Inter-eNB X2-based Handover preparations. The Mobility management (MM) receives a list with target cells from the RRM and decides to start an Inter-eNB X2-based Handover ;

4、 eNB 间 X2 切换出成功次数:

M8014C7 : SUCC_INTER_ENB_H,O The number of successful Inter-eNB X2-based Handover completions ;

5、 eNB 内切换出请求次数:

M8009C6: ATT_INTRA_ENB_HO, The number of Intra-eNB Handover attempts ; 6、 eNB 内切换出成功次数:

M8009C7 : SUCC_INTRA_ENB_HO, The number of successful Intra-eNB Handover completions ;

1.3 信令统计点 1.3.1 eNB 间 S1 切换 Counter eNB 间 S1 切换请求次数 Counter ID M8014C14 M8014C15 M8014C17 M8014C18 M8014C19 NetAct name INTER ENB S1 HO PREP INTER S1 HO PREP FAIL TIME INTER S1 HO PREP FAIL NORR INTER S1 HO PREP FAIL OTHER INTER ENB S1 HO ATT INTER ENB S1 HO SUCC

eNB 间 S1切换目标小区准备 M8014C16 失败次数 eNB 间 S1 切换尝试次数 eNB 间 S1 切换成功次数 eNB 间 S1 切换失败次数 M8014C20 INTER ENB S1 HO FAIL 统计点关系: M8014C14 = M8014C15 + M8014C16 + M8014C17 + M8014C18

M8014C18 = M8014C19 + M8014C20 (注:现网实际数据对不上)

1、M8014C14: INTER_ENB_S1_HO_PREP

Updated: This counter is updated following the transmission of an S1AP:HANDOVER REQUIREDm essage from the source eNB to the MME if this message prepares an Inter eNB Handover.

2、M8014C15: INTER_S1_HO_PREP_FAIL_TIME

Updated: This counter is updated at the expiry of the guarding timer TS1RELOCprep if the timer was started because of the preparation of an Inter eNB Handover.

3、M8014C16: INTER_S1_HO_PREP_FAIL_NORR

Updated: This counter is updated following the reception of an S1AP: HANDOVER PREPARATION FAILUR mEessage from MME to source eNB with cause \Available in Target Cell\of an Inter eNB Handover.

4、M8014C17: INTER_S1_HO_PREP_FAIL_OTHER

Updated: The number of failed Inter eNB S1-based Handover preparations due to the reception of an S1AP: HANDOVER PREPARATION FAILUmREes sage with a cause other than \Radio Resources Available in Target Cell.\

5、M8014C18: INTER_ENB_S1_HO_ATT

Updated: This counter is updated following the reception of an S1AP: HANDOVER COMMAND message from the MME to the source eNB in case that this message is received in response to the preparation of an Inter eNB Handover.
