3.1 Definitions

For the purposes of the present document, the terms and definitions given in TS 32.101 [2], TS 32.102 [3] and TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TS 32.101 [2], TS 32.102 [3] and TR 21.905 [1], in that order.

Organizational roles:

Master Operator (MOP): In Radio Access Network (RAN) and/or Core Network (CN) sharing scenarios, deployment and daily operation of shared network elements are entrusted to a single Actor, called the Master Operator. The Master Operator provides network and OAM&P services to other Operators, called Participating Operators (POPs). The Master Operator is the only one to have a direct OAM&P connection from its Domain Manager (DM) to the shared network elements.

Participating Operator (POP): Participating Operators are service providers who share, alongside other Participating Operators, the network (RAN and/or CN) facilities provided by the Master Operator. According to TS 36.300 [4] up to 6 operators can share a RAN.

Note: In a RAN/CN sharing scenario where Company A and Company B are POPs, MOP represents a role which can be played by either:

– Company A or Company B: in that case, Company A or Company B plays both roles, i.e. is the MOP and one of the POPs simultaneously, or

– A joint-venture between Company A and Company B, or

– A third-party entity: in this context, third party is referring to a wholesale mobile connectivity provider.

In the two latter cases, companies A and B rely on another company to play the role of MOP. This company cannot play the role of POP.

Management systems:

Master Operator Network Manager (MOP-NM): Network Manager enabling the Master Operator to manage the shared RAN and/or shared CN.

Master Operator Shared CN dm (MOP–SC-DM): Domain Manager enabling the Master Operator to manage the Shared CN.

Master Operator Shared RAN dm (MOP–SR-DM): Domain Manager enabling the MOP to manage the Shared RAN.

Participating Operator CN DM (POP-CORE-DM): Domain Manager enabling a Participating Operator to manage its own (not shared) Core Network.

Participating Operator Network Manager (POP-NM): Network Manager enabling a Participating Operator to manage its own (not shared) network and its portion of the shared network.

Participating Operator RAN DM (POP-RAN-DM): Domain Manager enabling a Participating Operator to manage its own (not shared) RAN.

Managed resources in a shared Radio Access Network (RAN) environment:

Shared RAN (S-RAN): A set of Radio Access Network elements shared among Participating Operators.

Managed resources in a shared Core Network (CN) environment:

Shared CN (S-CORE): A set of Core Network elements shared among Participating Operators. It may or may not include all core network elements. For example, the Participating Operators may share only the MMEs while having independent S/P GWs.
