    Hi Pix,

    Can you tell me the reasons behind SDCCH drops. Does it have any impact on MPD(minute per drop and if so how it effects?

    Hello Jane,

    In real environnment SDCCH congestion will depend on load of the cell ( cell high or low loaded ) and the type of the cell : LAC border, internal etc..

    Take a look at this example:
    Imagine you define 1 TS SDCCH on cell that got 1 TRX:

    Theoriticaly this cell can handle 2.74 Erl of traffic SDCCH at GOS 0.5 but this load is for One Hour period. Imagine at one time, a bus containing 40 people cross this area (Supposition is done that this cell is a lac border) , that is only 8 MS will do LA updating , the others 32 MS will wait and send again request one time again; this could lead to congestion if this cell is not loaded enough on busy hour to hidden the local time congestion.

    Regards.

    If you are using FH it is highly recommended to use SDCCH TS only on BCCH channel.

    Its not recommended to add more than 4 TS
