Hi khaldounh


On this thread. However, they are looking for the 'PW' for file

Throughput needs time to resolve, by first doing a UDP test to see if the air interface is OK.(interference may occur, congestion also)
Check quota data from billing side also.
Check default parameters also.
Core network needs to check for any limitation in RAB rate they send and you need to check the trace from RNC in "extended bit rate" to see the CN maximum data sent.
If UDP test is OK check RNC counters for transmission delays/packet drops/IPPM performance files and IUB.packetdrops on logical port(found at NodeB conters).

I have a project with an operator who having two issues in their Huawei 3G network, first one End user throughput, the second one is a Coverage issue.

Please if you have an guideline of how we troubleshoot such issues!

Thanks

For coverage improvement there is not much you can do apart from Sector addition, Site redesigns or CPICH power increase (Trade off with cell capacity) or New sites.

For End user throughput enhancement, You need to check the network load, If the HSDPA traffic is high then you need to add more carriers or Split the cell in to two cells using modern Antennas with Dual beams. Also please check if CS traffic on 3G part is higher it would eat up your HSDPA codes and will affect User throughput.

Pls check the IuB interface capacity as well. Which Scheduler algorithm are you using for HSDPA?

What is the configured Max transmit power of cell in your network?

[javvadhaider]

Also have you checked for high RTWP issue?

[dext]

there can be multiple issues due ot which you are having these issues,
can you confirm are your cells congested ?
how much throughput per cell you are having ?
what is the current CPICH power being used ?
have you performed DT ? how many active sets you have in the required area ?
what is the RTWP values for the cells
how many carriers are you working with ?
what is your required throughput ?
is there a possibility to improve the network coverage via some RET or redesigns ?
if you have HSDPA , how many HS-SCCHs you have defined in your network ?
