Dear TX friends,
It's the most important in TX planning that we have to do dimensioning for connections from remote BSCs to MSC, and interconnection between MSCs. Of course the traffic runs on these connections, hence the capacity, depends on how often each call type (intra/inter-BSC/MSC) occur. And this also depends on calling habits, social events, ... Yes, it's statical measurement based-on actual traffic. From the planning phases, we need at least a approximate calculation for the connection dimensioning to make a good performance against traffic congestion.
According to my experience, it's calculated like this:
1. Capacity of connection from a remote BSC to MSC = 1/4 * (Total of capacity from sites upstream to that BSC).
2. Capacity of interconnection between two MSCs = 1/4 * (Total of capacity from BSCs connected to bigger MSC)
For sure, we can use ratio 1/3 instead of 1/4.
I welcome all discussions, comments, and document shares!
Thanks much!
