  • This process is the cell handover process of SIM card 1 in the dual-card terminal. If the SIM card 2 in the terminal needs to perform cell handover, the process similar to Figure 1 needs to be repeated. The efficiency is low and the signaling overhead is large. For example, during the handover process of the SIM card 2, the terminal also needs to communicate with the SIM card 2. The current serving base station sends a cell handover request and so on. In addition, for terminals that support DR-DSDS, since only one radio frequency Tx channel is provided, if SIM card 1 and SIM card 2 perform cell switching at the same time, there may be SIM card 1 and SIM card 2 using the same channel at the same time. When the radio frequency Tx channel performs uplink transmission, for example, the SIM card 1 and the SIM card 2 simultaneously use the one radio frequency Tx channel to send a cell handover request to the current serving base station, thereby causing resource conflicts.
