Dear members, I am trying to understand how can I check if the Dynamic PDCH is activated or not with Huawei systems ?
Which parameter in the BSC dump, should I verify to ensure it is activated ?
I have found the parameter CHIDLHIGHTHR, Upper Threshold for CS Idle Channel Rate, When the channel is multiplexed by more than one user and the idle channel rate is above this parameter, a dynamic channel conversion request is raised. The CS idle channel rate can be calculated as follows: CS Idle channel rate = Idle cell channels for CS service/Available cell channels for CS service x 100%. Here, available cell channels refer to the number of available TCHFs or TCHHs in a cell. Idle cell channels refer to the number of the TCHFs or TCHHs that do not carry any CS service data in a cell. Two TCHHs are considered as one TCHF. When this parameter is set to "100", it is invalid. Setting this parameter to a large value other than 100 decreases the PS throughout when CS traffic is light.
Does this mean that if CHIDLHIGHTHR = 100 there is NO DYNAMIC PDCH ?
Setting this parameter to a small value increases the probability that CS services preempt PS resources when CS services burst, deteriorating the accessibility of CS services and stability of PS services. //this is contradictory shall we read "small value increases the probability that PS services preempt CS resources when PS services burst" ? //
Thanks for your support !!
