In manual mode, the PTI value contained in a particular ESM message is as
specified in the loaded scenario file.
Manual mode may be useful in the following situations:
• A UE is performing erroneously. For example: The UE initiates a procedure with one PTI
value, but incorrectly expects a corresponding response to contain a different or
default/uninitialized value.
• Testing a UEs handling of receiving a mismatched PTI value. For example: Testing the
rejection logic in the UE.
ESM layer messages contain a PTI which is used to uniquely identify transactions (for example: matching
responses to requests). The 3GPP specification does not outline a particular algorithm for how these
numbers are selected – and therefore the UE implementation for UL messages can vary. If the PTI of
messages (which are intended to be part of the same “exchange”) do not match, the UE discards DL
messages and indicates the cause of the PTI mismatch error. This function prevents this mismatch error.

TFT Handling
(Traffic Flow Template Handling)
If TFT Handling is set to Auto
, the Traffic Flow Aggregate requested by the UE in the Bearer Resource
Allocation Request is used to overwrite the Traffic Flow Template (or TFT) sent back to the UE in the
Activate Dedicated EPS Bearer Context Request. This essentially gives the UE what it asked for by
overwriting the value in the scenario file. If TFT Handling is set to Manual
, no overwrite takes place.

MCC
This value is carried in SIB1 and in the Attach Accept message (if GUTI is present). Setting this menu key
overwrites this value in both locations.
This setting overwrites the value defined in the currently loaded scenario file, when
the BSE emulator is not running (Mode > BSE > Emulator Mode- Stop is selected).
