Claim:
1. A communications apparatus, comprising: a plurality of SIM cards; an RF signal processing circuitry, comprising two or more RF signal processing circuits, wherein each RF signal processing circuit comprises one or more antennas and one or more hardware elements to perform radio frequency conversion; and a controller circuitry, configured for dynamically determining which SIM card to use which RF signal processing circuit for handling a radio activity of the SIM card according to priority of a plurality of radio activities of the SIM cards and RF signal processing capability of the RF signal processing circuits, wherein a number of the SIM cards is equal to or greater than a number of the RF signal processing circuits comprised in the RF signal processing circuitry, wherein the two or more RF signal processing circuits comprise at least a first RF signal processing circuit and a second RF signal processing circuit, the SIM cards comprise at least a first SIM card and a second SIM card, wherein the communications apparatus further comprises: a first modem, configured for processing a plurality of baseband signals and processing a plurality of communications procedures of the first SIM card; and a second modem, configured for processing a plurality of baseband signals and processing a plurality of communications procedures of the second SIM card, wherein the first modem provides information regarding a plurality of network-related parameters of a first wireless network that the first SIM card associates with to the second modem, and wherein the second modem schedules a radio activity for performing measurement in the first wireless network to obtain a measurement result according to the network-related parameters, performs the radio activity via the second RF signal processing circuit to collect the measurement result when the first RF signal processing circuit is dedicatedly used by the first SIM, and further provides the collected the measurement result to the first modem.
