  • Publication number: 20240040474
    Abstract: The present disclosure relates to a method for enabling a terminal to access a base station. The method includes: broadcasting, by a first BS not supporting a shared carrier, a first priority list, wherein the first priority list comprises information indicating that a priority of a BS that does not support the shared carrier is higher than that of a BS that supports the shared carrier; receiving, by the first BS, a first access request from a terminal, receiving, by the first BS, capability information from the terminal in a process of establishing a connection with the terminal; and completing, by the first BS, the connection with the terminal to enable the terminal to access a non-shared network, in a case where the terminal does not support the frequency band of the sharing operator in the shared carrier.

  • Publication number: 20240015627
    Abstract: This disclosure relates to a control method for a sharing mode of a base station, a shared base station and a communication system. The method of the present disclosure includes: acquiring a load of a standalone carrier of a first operator and a load of a standalone carrier of a second operator within a first preset time; converting one standalone carrier of the standalone carrier of the first operator and the standalone carrier of the second operator to a shared carrier, in a case where a total of the loads of the standalone carrier of the first operator and the standalone carrier of the second operator within the first preset time is less than a first threshold; and switching off another standalone carrier not converted to the shared carrier of the standalone carrier of the first operator and the standalone carrier of the second operator.
