Alejandro Molina Sanchez from Telefonica presented the EVOLVED-5G conference paper entitled “Offering the 3GPP Common API Framework as Microservice to Vertical Industries” on June 9th 2022. The 3GPP Common API Framework (CAPIF) has been standardized to guarantee a unique reference model for API-based service provisioning in 3GPP systems. The great potential of such framework is currently revealed due to the need for interaction between vertical industries and mobile networks. Towards realizing the above-mentioned interaction, we describe key functional aspects of CAPIF by focusing on related functional entities and APIs. In addition, we implemented the CAPIF Core Function, i.e., the main entity of CAPIF, as an effort to set the basis for an ecosystem where developers from vertical industries can easily develop network-interacting applications. To facilitate any further contribution in the area, our CAPIF implementation follows the principles of microservice programming, and it is released (open source) together with a set of evaluation tests. The paper has been created by Alejandro Molina Sanchez (Telefónica I+D, Spain); Anastasios-Stavros Charismiadis and Dimitris Tsolkas (Fogus Innovations & Services, Greece); David Artuñedo Guillen (Telefónica, Spain); Javier Garcia Rodrigo (Telefónica I+D, Spain).
