Important

The MonSub needs subscriber SUPI or IMSI in monitor subscriber command. The following are important actions:

  • As a prerequisite, the SMF must print the subscriber SUPI or IMSI in the logs.

  • Currently, SMF transaction logs are printing subscriber session keys which include subscriber SUPI or IMSI in the transcation logs.

  • The operator can pick the subscriber SUPI or IMSI from these logs.
