An RRC reconfiguration message is sent to the UE, containing the system informa-
tion values in a mobility control information element. This method is only used if an
RRC connection is established. Without RRC connection SIB paging is used.
●
"SIB Paging":
The UE is paged. This triggers the UE to evaluate the broadcasted system infor-
mation.
The UE is for example informed about changes of the following parameters: maximum
allowed uplink power P-Max, neighbor cell information, PUSCH open loop nominal
power, SRS enable/disable, PRACH configuration index and default paging cycle.
Remote command:
Keep RRC Connection
Selects whether the RRC connection is kept or released after attach.
●
"Enabled":
The RRC connection established during attach is kept when the attach procedure
is completed.
For a subsequent connection setup the already established RRC connection is
used. This speeds up the connection setup. When the dedicated bearer is released
via a disconnect, the RRC connection is still kept.
●
"Disabled":
–
For "Connection Type" = "Testmode", the RRC connection established during
attach is released immediately when the attach procedure is completed.
–
For "Connection Type" = "Data Application" there is an additional setting "Inac-
tivity Timer". The RRC connection established during attach is released when
the attach procedure is completed and there has been no activity on the con-
nection (no traffic) for the configured time.
The inactivity timer requires option R&S CMW-KS510. Without this option, the
RRC connection is released immediately when the attach procedure is comple-
ted.
Remote command:
Downlink MAC Padding
Activates or deactivates downlink padding at the MAC layer.
When no data (signaling or user data) is available from higher layers, an allocated
channel can be filled with padding bits (DL padding on). This scenario is foreseen in
many conformance tests.
Switching off DL padding is useful e.g. if the UE has problems to attach because the
DL signal contains padding bits.
If UL dynamic scheduling is enabled, MAC padding is disabled and grayed out.
