eUtranCell
The eUtranCell table models a geographical area of radio coverage that is implemented and supported by physical radio equipment, such as towers, amplifiers, and antennas.
The following tables describes the eUtranCell
table.
| Column name | Type | Constraints | Description |
|---|---|---|---|
| entityId | Integer | FOREIGN KEY NOT NULL |
The identifier of an eUtranCell entity from the
entityData table. |
| eUtranCellId | 64-character string | NOT NULL | Uniquely identifies a cell within a PLMN. It is often constructed from eNodeB ID + Physical Cell ID. |
| eUtranCellName | 64-character string | NOT NULL | Cell identifier or name of the cell. |
| physicalCellID | Integer | Physical cell identifier. Takes a value in the range 0 to 503. The
physical cell id is used by the cell to encode and decode the data that it transmits. It is
used in a similar way to the UMTS scrambling code. To avoid interference, neighboring cells
should have different physical cell identifiers. The physical cell id is derived from the
primary and secondary synchronization signals (PSS and SSS). The PSS takes a value from 0 to
2, the SSS takes a value from 0 to 167, and the physical cell id is determined based on the
following formula: |
|
| localCellId | Integer | Local cell id unique within the eNodeB. | |
| emsDistinguishedName | 255-character string | Distinguished name by which the eUtranCell is known to its element management system (EMS). | |
| channelBandwidthUI | Integer | Uplink channel bandwidth. Takes one of the following values in MHz
|
|
| channelBandwidthDI | Integer | Downlink channel bandwidth. Takes one of the following values in MHz
|
|
| maximumOutputPower | Float | Maximum power in Watts for the sum of all downlink channels that are allowed to be used simultaneously in a cell. | |
| userCapacity | Integer | Maximum number of pieces of user equipment (UEs) that can connect to this eUtranCell simultaneously. | |
| earfcnDl | Integer | E-UTRA Absolute Radio Frequency Channel Number (downlink). An integer value which identifies the downlink carrier frequency of the cell. | |
| earfcnUl | Integer | E-UTRA Absolute Radio Frequency Channel Number (uplink). An integer value which identifies the uplink carrier frequency of the cell. | |
| TAI | 64-character string | Tracking area identifier of the cell. This corresponds to the value stored in the NCIM trackingArea table. | |
| operationalState | Enumeration | Operational state of the LTE cell. Takes one of the following values:
|
|
| administrativeState | Enumeration | Administrative state of the LTE sector. Takes one of the following values:
