A base station controller (BSC), a mobile switching center (MSC) and a method for converting calling mode are provided, wherein the method comprises: the mobile switching center (MSC) sending a conversion notification message; the base station controller (BSC) establishing circuits of port A for both calling parties of a local switch according to the conversion notification message that it receives from the mobile switching center (MSC). The present solution overcomes the problem that a call is failed caused by using local switch to perform local call during the call which local switch is not suitable for, and is capable of converting from the local switch mode to non-local switch mode to achieve local call which is not suitable for local switch. |
