GSMA Operator Platform Group – East-Westbound Interface APIs
This specification defines the APIs that an Operator Platform should expose and use on its East/Westbound Interface. This interface is enabling use cases such as establishing the federation between Operator Platforms, sharing of edge nodes, providing access to Operator Platform capabilities in a visited network while roaming, etc. This version of the APIs enhances the functionality provided in the initial version by defining API extensions that allow the Service APIs that an Operator Platform may expose Northbound to an operator’s enterprise customers also on the interface between Operator Platforms. This ensure that the East/Westbound Interface definition does not have to be updated to enable the support of every new Service API in a federated environment. Next to this, it brings enhancements and clarifications based on the experience gained from initial deployments of the interface.
This functionality is not covered by existing APIs from SDOs and industry bodies. Therefore, the specification defines the complete API itself. For ease of use, this API is also provided as an Open API compliant yaml file.
