Network management method and system for a shared radio access network, RAN, infrastructure

A network management system for a shared Radio Access Network (RAN) infrastructure provided by a mobile network operator, the network management system comprising:

• a master operator network manager of the mobile network operator for managing the shared RAN infrastructure, wherein the master operator network manager is configured to receive service requests from one or more tenants and to allocate resources to accommodate the service requests, and
• wherein the master operator network manager is configured to cooperate with a network function, the network function being configured to consider information on mobility of a user or a set of users involved in a particular service request for deciding on resource allocations to the particular service request,
• wherein the capacity or resource broker implements a forecasting function that performs traffic forecasting or user mobility forecasting,
• wherein the traffic forecasting or the user mobility forecasting is performed by relying on historical data or current data, by exploiting temporal dependence forecasting models or spatial dependence forecasting models, by using signal processing based techniques, and by using recursive updating schemes.
