Re: Poor MPD in Huawei BSC 6900
hi,
to add to the thread,..the network..previously had baseband hopping & after swap we implemented Rf hopping it....
the MPD was poor ..hence we reverted back to base band..hopping , still no improvement in MPD..
can anyone share some other possible causes influencing high call drop...after swap..from e*******

Re: Poor MPD in Huawei BSC 6900
Can you segregate drop category (Signal Strength/Bad Quality/Sudden/Other/TA ??) Also direction (Uplink/Downlink ?) Because T200 times & Radio link failures indicate poor radio link between MS < ---- > BTS . If we want to draw conclusion about Hardware issue or other things let us answer the above questions.

Re: Poor MPD in Huawei BSC 6900
majority of the drops are due to signal strength & quality in the UL...any other information required, please let me know....

UL drop basically due to Planning issue. If earlier UL (SS & Bad Quality) drop was low comparatively. Through parameter check needs.
