IP Data Transfer Test for 2DL CA 5.2.
For MT8820C, Release10 or later DL 2CA
The IP data transfer with the carrier aggregation can be tested by installing the MX882012C-026 LTE FDD DL CA IP
Data Transfer option (hereafter MX882012C-026 option) in the MT8820C. Furthermore, using two MT8820C units
with the MX882012C-026 option and the MX882012C-011 2x2 MIMO DL option (hereafter MX882012C-011 option)
installed supports the IP Data Transfer Test for data rates up to 300 Mbps for DL CA and 2x2 MIMO.
NOTE 1: For the MT8820C, to use the MX882012C-026 option, the MX882012C-006/021 option must be installed in
the MT8820C functioning as PCC. Also, the MX882012C-006 option must be installed in the MT8820C
functioning as SCC.
NOTE 2: To test DL CA IP Data Transfer, two application servers and two EPS bearers must be established because
two MT8820Cs are used and the UE should support Multiple PDN Connection.
The DL CA IP Data Transfer Test requires two application servers because this solution uses two MT8820Cs: connect
the first application server to the 1000Base-T/1 port of the MT8820C functioning as PCC, and connect the second
application server to that of the MT8820C functioning as SCC.
Furthermore, two EPS Bearers must be established to perform IP data communication with two IP data streams.
The MT8820C will establish the default EPS Bearer as the first EPS Bearer during Registration, and establishes the
second EPS Bearer by performing the Dedicated EPS Bearer Activation after ensuring Connected state.
The following figure shows the Layer-2 structure and an image of the IP data streams.
Figure 5.2-1 Layer-2 Structure and Image of IP Data Streams (MT8820C)
The MT8820C functioning as PCC communicates with the UE using the IP data path of the Default EPS Bearer. The
MT8820C functioning as SCC communicates with the UE using the IP data path of the Dedicated EPS Bearer. The
Dedicated EPS Bearer has a TFT Filter allowing transmission of IP packets only when the source address of the IP
packet from the application server matches the IP address setting of the TFT filter. (Therefore, the address of the
TFT filter must match the IP address of the application server connected to the MT8820C functioning as SCC).
IP peak data rates up to 300 Mbps can be verified by performing IP communication between the UE and two
application servers.
For MT8821C, Release10 or later DL 2CA
The IP data transfer with the carrier aggregation can be tested by installing the MX882112C-026 LTE FDD DL CA IP
Data Transfer option (hereafter MX882112C-026 option) in the MT8821C. Furthermore, using the MT8821C unit
