ETSI's Multi-access Edge Computing (MEC) Industry Specification Group (ISG) has released its first standardised application programming interfaces (APIs) package to support edge computing interoperability.

According to ETSI, the five group specifications—GS MEC 009, GS MEC 010-2, GS MEC 011, GS MEC 012 and GS MEC 013—address general principles for mobile edge service APIs, application lifecycle management, mobile edge platform application enablement, Radio Network Information API and Location API.

The MEC application enablement framework is a generic framework that is applicable to every environment aimed at opening up the network and exposing information towards authorised third-party applications. Utilising a unique application enablement (API) framework across the industry ensures common practices and interoperability for developers when interfacing their applications with the operator’s system. This promotes innovation and accelerates development of third-party applications, enabling operators to further capitalise on their network investments, ETSI said.

The MEC API principles specify a generic set of API design principles and patterns, as well as guidance for their documentation. Compliance with these principles ensures consistency across APIs. The work was inspired by the works of the TM Forum and Open Mobile Alliance (OMA), as well as approaches currently used in developer communities.

The release also includes APIs for two key value-adding MEC services: Radio Network Information Service (RNIS) and Location Service (LS). The RNIS is a service that provides radio network related information to MEC applications and to MEC platforms. Such information may be used to optimise existing services and used as an input to new types of services utilising the real-time access to radio conditions and related events. The LS leverages the Zonal Presence service developed by Small Cell Forum (SCF) and is built upon the OMA specification "RESTful Network API for Zonal Presence."

Additional service APIs, including an API for bandwidth management, are expected to be released shortly.
