Apparatuses and methods for implementing o2 related functions definitions within a telecommunications network

A method, implemented by a non-real-time radio access network intelligence controller (NRT-RIC) framework in an open radio access network (O-RAN), for providing R1-O2 related services, the method comprising:

• receiving, from an rApp hosted by the NRT-RIC, at least one request of at least one R1-O2-related service via an R1 interface within the O-RAN architecture between rApps and the NRT-RIC framework;
• and
• sending, from the NRT-RIC framework to the rApp, at least one response of the at least one R1-O2-related service via the R1 interface;
• wherein the at least one request and the at least one response are implemented as data types comprising a plurality of R1 data models of an R1 application protocol that enable the NRT-RIC framework and the rApp to produce and/or consume data of the at least one R1-O2 related service in the NRT-RIC.

A non-transitory computer-readable recording medium having recorded thereon instructions executable by at least one processor implementing a non-real-time radio access network intelligence controller (NRT-RIC) framework in an open radio access network (O-RAN), to perform a method for providing R1-O2 related services, the method comprising:

• receiving, from an rApp hosted by the NRT-RIC, at least one request of at least one R1-O2-related service via an R1 interface within the O-RAN architecture between rApps and the NRT-RIC framework;
• and
• sending, from the NRT-RIC framework to the rApp, at least one response of the at least one R1-O2-related service via the R1 interface;
• wherein the at least one request and the at least one response are implemented as data types comprising a plurality of R1 data models of an R1 application protocol that enable the NRT-RIC framework and the rApp to produce and/or consume data of the at least one R1-O2 related service in the NRT-RIC.
