Hello people :)

Do you have some Huawei documents about CDMA2000 Radio Network planning and optimization?

please if have, share it for me :)

Thanks


1 Preface
2 Call Drop Problems
2.1 Call drops caused by incorrect settings of the DIP switches on the BCIM board
2.2 Call drop due to the fault of the BCKM board
2.3 C0b Call drops and A2 interface call drop due to the fault of the FMR
2.4 The C05 (a call drop indicator) rises after IP transmission is used on the A interface
2.5 Call drops caused by the mismatch between the maximum transmit power of the CDMA TCH and the pilot power
3 Handoff Problems
3.1 Mobile-assisted hard handoff (MAHHO) failures caused by the excessively small candidate frequency search window
3.2 The strong legs of the EV-DO network cannot join the active set when the FMR board is faulty
3.3 The soft handoff success rate decreases due to insufficient CIDs of the PVCs from the BIE to the MUX
3.4 EVDO handoff failure because no inter-EVDO frame soft handoff is configured
3.5 A case of interconnection and hard handoff failure between Huawei BSC and the BSC of vendor Z in country P
4 Interference Problems
4.1 The RSSI of a BTS is slightly high due to the interference from a repeater
4.2 The difference between the main RSSI and the diversity RSSI is sometimes normal but abnormal at the other time of a day due to incorrect connection of the spatial diversity antennas of the sectors
5 Data Configuration Problems
5.1 The call setup success rate and the handoff success rate sharply decrease due to insufficient signaling link bandwidth
5.2 MS access failures caused by the small value of MAX_CAP_SZ
5.3 Hard handoff failures caused by the small search window size set on the BSC of vendor M
5.4 The data of the RFMT cannot be traced due to incorrect settings of signaling software parameters of the BTS
5.5 Many A22 access failures after the BSC is upgraded
5.6 Failure of all the subscribers in the network to make calls because the INIT_PWR parameter is set too large
5.7 Call setup failures caused by poor cooperation between Huawei MSC and the HLR of other vendors during network swap
5.8 OTAPA operation failure of the CDMA fixed station terminal due to inconsistent A_KEY value
5.9 Policies for solving the Walsh congestion of the carriers set with CDMA1x data service priority
6 Problems with Tools and Instruments
6.1 A case of troubleshooting the dongle of Dingli
6.2 Failure of the Huawei C5300 to connect the PC for test due to the incorrect mobile phone port type set
6.3 A case of troubleshooting the connection between Dingli software and Huawei 1900M fixed station ETS22
7 BSS Equipment Problems
7.1 Congestion occurs to the blocked carriers after access macro diversity is enabled
7.2 Low call setup success ratio and no hardware alarm display due to the fault of the chip on the CCPM board
7.3 The call setup success rate decreases due to a fault of the FMR board
7.4 The BTS is abnormal due to a hardware fault of the NOD board of the ETS450-BSC
7.5 The transmit power of all the BTSs in the network rises and the voice quality of the BTSs is poor due to the clock fault of the GCKP board after the frequencies of the BSC are modified
7.6 The BAM server cannot synchronize with the EWS due to a virus of the MSN Messenger
7.7 The BTS alarms do not indicate the faulty BTS because data update and synchronization is not performed on the M2000 after the BTSs are upgraded
8 EVDO Problems
8.1 The real-time map of the CAIT disappears because the GPS does not work
8.2 The map does not match the BTS longitude and latitude during the DO network drive test with the CAIT
8.3 The PPP connection cannot be released when the subscriber is abnormally disconnected
8.4 The connection between the PCF and the PDSN fails due to the failure of NTP time synchronization
8.5 How to differentiate DO-RA services from DO-R0 services?
8.6 Low download rate of EVDO data services due to insufficient E1s and incorrect service link configuration
9 Other Problems
9.1 Several methods for setting in-car loss in the U-net
9.2 The terminals of vendor Z automatically power off in a Huawei network
9.3 A high FER caused by the demodulation of the FCH after the connection of the MS is released

Thank you for sharing such nice post,
its good,
i always see there is very less post on CDMA.

yes here is less posts about CDMA, more of them are on UMTS and GSM

Hi friend,

If you want to learn about CDMA2000 RNP&RNO, please search in the forum.

I already shared a full Huawei course (for Huawei internal;))
