    Abstract: Embodiments of the present application provide a switching control method, an apparatus, and a wireless communications network. The switching control method in the present application includes: receiving a path switching request sent by a radio node (RN), and obtaining information about user equipment (UE), an identifier of a source RN, and an identifier of a destination RN according to the path switching request; determining, according to the information about the UE, the identifier of the source RN, and the identifier of the destination RN, a function node (FN) that provides a service to the destination RN, and generating a path switching rule according to the FN; sending the path switching rule to an ingress network element. The embodiments of the present application resolve a problem that when system performance is insufficient, free extension cannot be performed due to mutual restriction between multiple functions.

    Abstract: A routing node includes: at least one optical buffer, a switching node, and at least one transmission waveguide, where an output end of each optical buffer is connected to an input end of the switching node; each transmission waveguide is connected to an output end of the switching node. The optical buffer is configured to parse a received optical signal to obtain an identifier of a destination routing node, and send the identifier to the switching node. The switching node determines whether an output port required by the destination routing node is in an idle state or a busy state; and control the optical buffer to store the optical signal if the output port is in a busy state; or send the optical signal to the destination routing node if the output port is in an idle state.

    Abstract: Embodiments of the present invention disclose a network selection method, an apparatus and a base station. The method includes: determining each of networks satisfying requirements of a user when the user initiates a service or transmits a service; estimating an average energy efficiency of a system during service transmission after the user selects to access each of the networks; selecting a network which can make the average energy efficiency of the system reach a preset threshold value to serve the user. Embodiments of the present invention solve a problem in the prior art that, because no consideration is given to network energy consumption in the network selection, system energy efficiency is reduced. Through comprehensive consideration of network energy efficiency and system energy efficiency, the need for energy saving and consumption reduction is met.
