Blind Handover
The Blind Handover is a PXT initiated redirection to a new EARFCN and/or Cell ID.
You must have an rrcReconfiguration handover message within the scenario file and assigned to the BSE >
Func > Handover key menu. The Blind Handover feature enables you to send the rrcReconfigurarion
message in its original form, or overwrite EARFCN and/or Cell ID content using the front-panel menu keys
or the remote command interface.
Setting the value of BSE > Func > Handover > Handover Setup Mode to Default
uses the value specified
in the scenario file. Setting this parameter to Blind
utilizes the values specified in the Handover Setup Mode
key menu: DL/UL EARFCN and Target Cell ID.
It is necessary to set both the UL and DL EARFCN values because these values are not coupled, when
using this feature.
Selecting BSE > Func > Handover > Message Name > Blind HO = Send
sends a message to the UE
instructing it to move to the specified EARFCN. The PXT then reconfigures its UL and DL frequencies
and/or Cell ID to match the HO conditions. When the message is sent, and the HO is completed
successfully, the following transactions are displayed on the PXT:
• DL: RRCConnectionReconfiguration
• UL: RRCConnctionReconfigurationComplete
A successful Blind Handover completes very quickly.
If the handover fails the UE will most likely issue an RRCConnectionReestablishmentRequest in which case
you should see the following sequence of RRC messages:
• DL: RRCConnectionReconfiguration
• UL: RRCConnectionReestablishmentRequest
• DL: RRCConnectionReestablishment
• UL: RRCConnectionReestablishmentComplete
• DL: RRCConnectionReconfiguration
• UL: RRCConnctionReconfigurationComplete
The Re-establishment process may take several seconds..
