Abstract: Embodiments of the disclosure describe a method for managing a PULL notification message trigger procedure to enable a service enabler architecture layer (SEAL) notification management client (SNM-C) 200 to share a pull notification message trigger indication to a SEAL notification management server (SNM-S) 300. The updates to the existing create notification channel procedures to manage a pull notification message triggers (PNMT) in SEAL notification management services are performed. Further, a new pull notification message trigger information field represents the SNM-C 200 indication to support such application triggers to initiate the pull notification message procedure. The method for the SNM-C 200 to encode the pull notification message trigger information field as part of the create notification channel request information element sent in a HTTP request body to the SNM-S 300.
