A method for managing resources of a converged fixed access and mobile radio telecommunications network, some of the resources being implemented in a virtualized and remote form in the network, optical resources of the network being allocated between an optical router and a plurality of optical modems of the network is disclosed. A module for centralized management of the mobile radio resources of the network implements receiving a performance indicator for a mobile radio part of the network transmitted by a base station of the network connected to one of the optical modems and/or by a module of remote virtualized radio functions in the network; estimating the optical resource requirements of the mobile radio part from the performance indicator, providing information representative of the optical resource requirements; and transmitting the information of the optical resource requirements to a module for centralized management of the fixed access and optical resources.
