enbFunction

The enbFunction table models the role of the eNodeB entity within a network hardware node. Multiple enbFunction instances may be implemented within a single network hardware node. The eNodeB entity manages radio air interface communication with users of the LTE network. Each eNodeB controls one or more cells which are geographic areas of radio coverage.

The following table describes the enbFunction table.
Table 1. enbFunction table
Column name Type Constraints Description
entityId Integer FOREIGN KEY

NOT NULL

 The identifier of an enbFunction entity from the entityData table.
eNodeBId 64-character string NOT NULL Identifier of the eNodeB.
eNodeBName 64-character string NOT NULL User friendly name of the eNodeB.
MCC 3-character string   An eNodeB can support multiple PLMNs. The MCC attribute specifies the Mobile Country Code (MCC) of the primary PLMN supported by the eNodeB. Primary PLMN usually means the sole PLMN or the PLMN of the operator responsible for the operation and maintenance of the eNodeB. The MCC consists of three digits.
MNC 3-character string   An eNodeB can support multiple PLMNs. The MNC attribute specifies the Mobile Network Code (MNC) of the primary PLMN supported by the eNodeB. Primary PLMN usually means the sole PLMN or the PLMN of the operator responsible for the operation and maintenance of the eNodeB. The length of the MNC (two or three digits) depends upon the value of the MCC.
supportedPLMNs Integer   Count of the number of PLMNs (Public Land Mobile Networks) supported by the enbFunction.
emsDistinguishedName 255-character string   Distinguished name by which the enbFunction is known to its element management system (EMS).
emsIpAddress 39-character string   IP address of the element management system.
vendorName 64-character string   Vendor or manufacturer of the enbFunction.
vendorModuleType 64-character string   Vendor-specific eNodeB type.
softwareVersion 64-character string   Vendor-specific eNodeB software version.
userCapacity Integer   Maximum number of active pieces of user equipment (UEs) that can connect to this eNodeB simultaneously.
maximumOutputPower Float   Maximum output power of the eNodeB.
operationalState Enumeration   Operational state of the enbFunction. Takes one of the following values:
  • Enabled
  • Disabled
  • Other
  • Unknown
administrativeState Enumeration   Administrative state of the enbFunction. Takes one of the following values:
  • Unlocked
  • Locked
  • Shutting Down
  • Other
  • Unknown
backHaulConnection 39-character string   IP address of the first hop backhaul device to which the enbFunction is connected; for example, the IP address of a cell-site router.
