Abstract: A communications apparatus includes multiple SIM cards, a RF signal processing module including two or more RF signal processing units which including at least a first RF signal processing unit, and an arbiter configured for dynamically determining which SIM card to use which RF signal processing unit for handling a radio activity of the SIM card according to priority of radio activities of the SIM cards and RF signal processing capability of the RF signal processing units. A number of the SIM cards is equal to or greater than a number of the RF signal processing units included in the RF signal processing module.

Abstract: A method for disaster roaming includes initiating disaster roaming search by user equipment (UE) if one of following conditions occurs: the UE receives System Information Block (SIB) from a first Public Land Mobile Network (PLMN), the UE receives a message and/or an information element from the first PLMN indicating an occurrence of a disaster or availability of disaster roaming, and the UE determines out-of-service (OOS) from the first PLMN. The SIB includes at least one disaster roaming information element. The method further includes searching by the UE for a second PLMN to register.

Abstract: A controlling method for a wireless communication device is provided. The controlling method for the wireless communication device includes: attaching a first Universal Subscriber Identity Module (USIM) to a Long-Term Evolution (LTE) network; determining whether a second USIM is camped on the LTE network; detecting whether a paging collision is happened, if the second USIM is camped on the LTE network; generating a requested International Mobile Subscriber Identity (IMSI) offset for the second USIM, if the paging collision is happened, wherein the requested IMSI offset is 1 or min(T, nB)−1, T is a default paging period and nB is a number of paging occurrences within the default paging period; transmitting an attach request with the requested IMSI offset to the LTE network for the second USIM; receiving a negotiated IMSI offset from the LTE network; and attaching the second USIM to the LTE network with the negotiated IMSI offset.
