mmeFunction

The mmeFunction table models the role of the Mobility Management Entity (MME) within a network hardware node. Multiple mmeFunction instances can be implemented within a single network hardware node. The MME is the main signalling control element in the core network and is the key control node for enabling user equipment access to the core network.

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

NOT NULL

 The identifier of an mmeFunction location entity from the entityData table.
MMEC 64-character string   MME code. Uniquely identifies an MME within an MME Group. This attribute consists of 8 bits.
MMEGI 64-character string   MME group identifier. Uniquely identifies an MME Group within a public land mobile network (PLMN). This attribute consists of 16 bits.
mmeName 64-character string NOT NULL Uniquely identifies an MME when more than one MME configured on same device.
MCC 3-character string   An MME can support multiple PLMNs. The MCC attribute specifies the Mobile Country Code (MCC) of the primary PLMN supported by the MME. Primary PLMN usually means the sole PLMN or the PLMN of the operator responsible for the operation and maintenance of the MME. The MCC consists of three digits.
MNC 3-character string   An MME can support multiple PLMNs. The MNC attribute specifies the Mobile Network Code (MNC) of the primary PLMN supported by the MME. Primary PLMN usually means the sole PLMN or the PLMN of the operator responsible for the operation and maintenance of the MME. The length of the MNC (two or three digits) depends upon the value of the MCC.
supportedPLMNs Integer   Count of the number of PLMNs supported by the MME.
emsDistinguishedName 255-character string   Distinguished name by which the MME 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 MME.
vendorModuleType 64-character string   Vendor-specific MME type.
softwareVersion 64-character string   Vendor-specific MME sofware version.
operationalState Enumeration   Operational state of the mmeFunction. Takes one of the following values:
  • Enabled
  • Disabled
  • Other
  • Unknown
administrativeState Enumeration   Administrative state of the mmeFunction. Takes one of the following values:
  • Unlocked
  • Locked
  • Shutting Down
  • Other
  • Unknown
