GuestHi Akinbola,
If you think its temperory increase in sdcch congestion, Then you can increase the sd cofig from combined to non combined or with additional sd timeslots. And check whether the sd traffic is geniune.
Or else, check whether what is the maximum cause of this rise in sd traffic. Probably its a new location area boundary.
Best way to overcome this spurious sd congestion is using dynamic sd reconfigration.
Best regards,
Garry !!

GuestHi Pary,
If you use 1 LAC/BSC, with enough signalling then probably you can balance with paging & loc update. But the signalling design is totally dependent on the TRX config for that BSC and the type of signalling you use in your network.
Who is your BSS vendor ?
Best regards,
Garry !!

Guesti have some site x with lower band (900) & upper band (1800) are in the same location, but they are integrated in differents MSCs. Is this configuration affects some ressources: LU, Sig congestion,…

GuestHI chah
For 1LAC/BSC you have some benefits in term of moderated signaling on BSCs, A interface & MSC. SO it is recommended in first network planning.
BUT so after, according to your LA optimization & BSC capacity you can use LAC/different BSC, & furthermore you can use LAC/diff MSC but seldom.& it increase the paging signaling on your BSCs, MSCs & A links, so you must balance between LU events, & the the paging load followed your MSC/BSC/LA configuration.7th April 2006 at 15:45 #35690wael

GuestIt’s a very simple recipe for success : Good frequency planning, good cell coverage, and a non-faulty hardware 🙂

Guestthere is no such thing as a counter for location update, and the default is usually 2hours for mororolla
