Feature Description

MME Manager distributes/redistributes equal number of eNodeB SCTP connections across MME Managers. As a result of network outages, the distribution of eNodeB SCTP connections by the MME Managers were uneven. The distribution of eNodeB SCTP connections across MME Managers is made even.

Configuring MME Manager

Use the following configuration to configure the MME Manager related commands and to correct the stack eNB entry in mmedemux .

mme mmedemux s1ap-sync mmemgr { all | instance instance_value }

Notes:

  • mme : Configures the MME exec commands.

  • mmedemux : Configures the MME Manager related commands.

  • s1ap-sync : Synchronizes with s1ap association count with MME Manager-Archive with all instances of MME Manager.

  • mmemgr : Synchronizes up with MME Manager on eNodeB list.

  • all : Synchronizes up with MME Manager on eNodeB list with all instances.

  • instance instance_value : Synchronizes with MME Manager on eNodeB list with specific instance. instance instance_value must be an integer from 1 to 48.

mme mmedemux audit-with { all | instance instance_value }

Notes:

  • mme : Configures the MME exec commands.

  • mmedemux : Configures the MME Manager related commands.

  • audit-with : Allows mmedemux to free up the enodeB archive and to rebuild using audit from the MME Manager database. Clears any blocked eNB entry in mmedemux .

  • all : Synchronizes up with MME Manager on eNodeB list with all instances.

  • instance instance_value : Synchronizes with MME Manager on eNodeB list with specific instance. instance instance_value must be an integer from 1 to 48.
