Abstract
A method of accessing services affiliated with a service provider is disclosed. An issuer performs a bootstrap procedure with the at least one discovered service provider. The issuer performs a discovery procedure to determine available service capability layers (SCLs) supported by the at least one discovered service provider. The issuer transmits a domain name system-based service discovery (DNS-SD) query from the issuer to a DNS-SD M2M service discovery function (MSDF) server. The DNS-SD MSDF server is provisioned with SCL discovery records. The DNS-SD MSDF server is registered with a public DNS registrar entity. The SCL discovery records include, for each SCL, a type of M2M service capabilities supported by each SCL and a class of M2M services supported by each SCL. The issuer receives SCL discovery records from the DNS-SD MSDF server in response to the DNS-SD query.
