Methods and terminal devices for making media calls via a network are provided. In some embodiments, a first terminal device includes interface circuitry and processing circuitry. The processing circuitry detects, in response to a success reception of a first data packet of first media that is send by a second terminal device during the media call, whether a packet loss occurs in the first media. When a packet loss is detected, the processing circuitry obtains network status information of the network. Further, the processing circuitry determines a probability threshold in association with a retransmission request to the second terminal device for retransmitting a second data packet. Based on the probability threshold, the processing circuitry determines a network requirement condition for the retransmission request. When the network status information satisfies the network requirement condition, the interface circuitry sends the retransmission request; otherwise the retransmission request is cancelled.
