12. Send the HO message “RRC_Handover” by selecting Func > Handover > Message Name (Select message)
> Send.
13. On the Master PXT originating the handover, you now see the RRCConnectionReconfiguration message.
The destination (Slave PXT) displays the RRCConnectionReconfigurationComplete message. At this point
the handover has completed successfully and the UE is connected to the Slave PXT.
14. Verify that you can still ping the IP address of the destination server: 192.168.1.230.
15. Perform handover from Slave to Master by starting at step 11, above.
16. Verify IP continuity by pinging the IP address of the destination server after each handover.
Inter-Radio Access Technology (I-RAT) Handovers
The PXT can be used in conjunction with the Agilent E5515 (8960) to perform inter-RAT (Radio Access
Technologies) operations. This combination of instruments enables you to test multi-mode wireless devices
for inter-RAT handovers between legacy 3GPP and E-UTRAN (LTE) using the 8960 as the UTRAN or GERAN
simulator. Refer to the table below for descriptions and requirements of both the optimized and nonoptimized handovers.

UTRAN/LTE & GERAN/LTE Inter-RAT Handovers
Note that throughout this section, the term UTRAN is used to refer to the WCDMA technology running as
the E6703 or E6785 application on the 8960. Similarly GERAN refers to GSM, GPRS and EGPRS technologies
running as the E6701 or E6785 applications. (Refer to the appendix of the Agilent PXT Getting Started Guide
for an acronym descriptive). Collectively UTRAN and GERAN are referred to as the ‘legacy 3GPP’ networks.
The following test scenarios are supported using the 8960/PXT combination:
•
Cell reselection between UTRAN and LTE (bi-directional, UE-initiated only).
•
Cell reselection between GERAN and LTE (bi-directional, UE-initiated only).
•
PS (Packet Switched) Handover between UTRAN and LTE (bi-directional, network-initiated only).
•
PS Handover between GPRS/EGPRS and LTE (bi-directional, network-initiated only).
•
RRC (Radio Resource Control) Release with Redirection from LTE to WCDMA.
•
RRC Release with Redirection from WCDMA to LTE1
•
CSFB (Circuit Switched Fallback) from LTE to either UTRAN or GERAN.
