Hello,
I observed by RNO the MHT on interface A(A_Duration_Avg) and MHT on Air interface(RTCH_Duration_Avg), I saw that the MHT on interface A is significatively greater than on the interface Air.
I have no explanation why these values are not equal or with a slight delta in part because of the congestion on the A interface there are no other factors that explain a difference so greater.
Does someone has worked on it or have an explanation?
Can intra-cell handovers cause this? Every intra-cell handover causes a new TCH allocation without new A interface allocation. This can result in lower values of TCH MHT.
Pan, this Two features are not implemented.
I think that the Hand Over Intra/Inter Cell are the cause of this problem because it cause a number of allocation too bigger but in A interface there’s no new allocations.
what do you think?
I was wrong : Intracell HO can cause a lower value of Mean Holding Time.
(A TCH is seized whenever a 48.058CHANNEL_ACTIVATION message is about to be sent to the cell to activate a full rate TCH channel for normal assignment or handover.)
