In order to expand the air port bandwidth of SIM card mobile terminals and improve the communication speed of SIM,a SIM card initial information aggregation algorithm based on digital twin technology and time variation coefficient is proposed.Using digital twin technology to obtain twin data containing initial information in the SIM card,construct virtual components of the SIM card.arrange initial information in a chronological manner,analyze time variation coefficients,deter-mine and partition initial information to be aggregated,calculate density threshold functions within each grid unit,construct evaluation functions,obtain the optimal aggregation coefficient,and complete the aggregation of SIM card initial informa-tion.The experimental results show that the uplink communication rate and downlink communication rate are improved to 90Mbps,and the aggregation effect of SIM card initial information is good.It can effectively expand the air port bandwidth of mobile communication terminals and enhance communication signal strength.
