Figure 3-15: Quick Setting
a. When connecting the eNB to the Baicells CloudCore, you must use PLMN ID =
314030 and MME IP addresses 10.3.0.9 and 10.5.0.9.
b. Bandwidth setting may be 5, 10, 15, or 20 MHz.
c. Select the correct frequency within the band range for this eNB to use.
d. Select the SubFrame Assignment (SFA or SA). SFA determines the amount of
transmission resources in the downlink and the uplink, and is expressed as a
ratio of DL:UL. For example, setting the SFA value to 1 means a 2:2 ratio will
be applied to transmissions, where an equal number of RF resources will be
available in the downlink and in the uplink.
i. 0 = 1:3
ii. 1 = 2:2
iii. 2 = 3:1
e. Select the Special SubFrame Pattern (SSF) value, either 5 or 7 (default). This
setting determines the length of the guard period for switching between
downlink and uplink transmissions. An SSF = 5 provides a longer guard time
and is typically used for cells covering more distance. The farther the distance
the UE is from the eNB the more likely it is you will need to use a longer guard
period of SSF = 5.
f.
Enter a unique Physical Cell Identifier (PCI) for this eNB, between 0 - 503.
g. Make sure the Cloud EPC field is enabled in order to connect to the Baicells
CloudCore.
h. Enter a Cell ID for a cluster of eNBs on the same tower or other structure. The
Cell ID field is equivalent to the LTE E-UTRAN Cell Identity (ECI).
i.
As mentioned in step 5 above, to use the Baicells CloudCore make sure the
PLMN = 314030 and the MME IP addresses = 10.3.0.9 and 10.5.0.9.
j.
The Tracking Area Code (TAC) field is used to identify a cluster of cell sites.
Enter a value between 0 - 65535 for each unique TAC ID in your network.
