4.1 General

With regard to the control and monitoring of their Power, Energy and Environmental (PEE) parameters, base stations can be of two different types:

# either they have built-in sensors, which communicate with DM through Type-1 interface. In turn, DM communicates with the NM-RMS (see figure 4.1.1);

# or they have external sensors, which communicate with the NM-RMS via:

– either XCU/DGU (see figure 4.1.1)

– or vendor-specific RMS (VS RMS) (see figure 4.1.1).

The NM-RMS collects PEE parameters from part or whole of the radio access network and may also control PEE related parameters through either DM(s) and/or XCU/DGU(s) and/or VS-RMS(s).

For this reason, it is beneficial to standardize the interface to control and monitor PEE parameters between the NM-RMS on the one hand and DM, XCU/DGU and VS-RMS on the other hand. This TS series specifies this Type-2 interface (see TS 32.101 [2]).

4.2 Architecture

The NM-RMS is a located in the NM layer (see also TS 32.101 [2]).

VS-RMS is located in the DM layer (see also TS 32.101 [2]).

XCU/DGU is located in the Network Element layer (see also TS 32.101 [2]).

Possible interfaces between all these entities are depicted in figure 4.1.1. The three possible scenarios for this IRP are depicted in figures 4.2.1, 4.2.2 and 4.2.3.

4.3 Functionality

Both DM, XCU/DGU and VS-RMS offer a capability allowing the NM-RMS to control and monitor PEE parameters of one or more base stations. This TS series specifies the information model exposed by the DM, XCU/DGU and VS-RMS to the NM-RMS, and the operations enabling the control and monitoring of PEE parameters from the NM-RMS.

This TS series describes two non-mutually exclusive solutions:

# Solution 1: based on existing 3GPP Interface IRPs to support controlling and monitoring of PEE parameters of base stations with built-in sensors. This solution may be used for the interface between DM and NM-RMS.

# Solution 2: describing simplified functionalities according to ETSI ES 202 336-1 [4] and ES 202 336-12 [3]. This solution may be used for the interfaces between XCU/DGU and NM-RMS, between VS-RMS and NM-RMS and between DM and NM-RMS.

Solution 1 is only applicable in case of scenario depicted in figure 4.2.3.

Solution 2 is applicable in case of all scenarios depicted by figures 4.2.1, 4.2.2 and 4.2.3.
