LTE CDU Interface

Main card plays role as main processor, GPS signal receiver and distributor, and as a network interface. It is responsible for communication path configuration between UE and EPC, Ethernet Switching functionality for internal Samsung MBS, and System OAM. Also, it manages entire hardware and software statuses within the Samsung MBS, allocates/manages resources, and collect/report the alarm status information to LSM (LTE System Manager)

11/60

LTE CDU Debug Cable (Connecting to Main Card)

The main card manages the status of all hardware and software in the eNB and reports status information to the LSM in addition, the main card allocates and manages the resources of the eNB. Connection directly to the main card is possible via a Laptop or PC using a debugging cable (DB-9 to USB cable). Connect one end of the debugging cable to PC and the other end to the DBG port of the main card of CDU maintenance window as shown in the figure below.

Throughput Test (Peak DL)

The target of this test is to measure the peak DL data throughput with single stationary end user equipment in favorable SINR locations.

Pre-requisite 1) A laptop computer to monitor the UE and DM tool for UE 2) G- bit Ethernet backhaul resource is assumed. 3) UDP server at eNB side and UDP client at UE side are required. 4) UDP server should be able to afford over 150 Mbps throughput. Test Process 1) Locate a test UE and laptop where DL SINR > 28 dB (Area in the trial network providing reproducible maximum data rates.) 2) Connect the UE to eNB (Call setup the UE.) 3) Run UDP client at the server. 4) Generate downlink UDP traffic and observe the single UE downlink throughput.

Expected Result 1) Meet the throughput criteria

Handover Test

This test is verify basic mobility between Samsung LTE system

Pre-requisite 1) LTE network system (eNB/EPC/HSS) configured properly. 2) UE set & subscribed in LTE network properly. Test Process 1) Set up two cells from each eNB 2) Check neighbor configuration of each eNB (X2 Setup) 3) Attach the UE at first cell. 4) Send continuous ping from UE side to application server. 5) Decrease downlink signal power of source cell and increase target cell. 6) Repeat step ‘5’ with other direction.
