A method, apparatus, and a storage medium for determining a network switching resource are provided. The method may be applied to a terminal. The terminal may send, when establishing connection to a first operator network in at least two operator networks, pre-stored first information of a second operator network in the at least two operator networks, and second information of a terminal in the second operator network to the first operator network. The terminal may determine time-domain resources for disconnection to the first operator network and activities in the second operator network according to first configuration information sent by the first operator network and/or second configuration information sent by the second operator network after establishing communication connection to the second operator network.
