    Abstract: A radio communication device may include a measurement circuit configured to perform radio measurement to identify one or more cells of a combined CS-PS network in anticipation of circuit-switched orders, and a control circuit configured to identify a pending circuit-switched order supported by the combined CS-PS network while attached to a current network, and switch from the current network to the combined CS-PS network to engage in the pending circuit-switched using a selected cell of the one or more cells.

    Abstract: A wireless communication device is described in one example comprising a first communication module circuitry to communicatively couple the wireless communication device with a first network, the first communication module circuitry to receive a reject message from the first network to disable communications with the first network, a processor to store, in memory, information corresponding to the communications with the first network; and a second communication module circuitry to communicatively couple the wireless communication device with a second network, the second communication module circuitry to send the information to a remote service monitor, wherein the first communication module circuitry includes a first Subscriber Identity Module (SIM) or a first virtual SIM and the second communication module circuitry includes a second SIM or a second virtual SIM. Other embodiments may be described and/or claimed.

    Abstract: A user equipment (UE) explicitly accounts for a coverage enhancement (CE or sometimes called enhanced coverage) feature in a public land mobile network (PLMN) search and/or selection. By explicitly using CE indicators in PLMN search and/or selection, a UE can determine whether to use a PLMN that may only be available in CE mode for voice services or data services, or fail to meet criteria, such as high data rate, that cannot be provided in CE mode. For example a UE can use the PLMN search and/or selection with (1) automatic PLMN selection at switch-on or recovery from lack of coverage, (2) higher priority PLMN selection, (3) manual PLMN selection, and/or (4) limited service capabilities while in CE mode.

    Abstract: A communication device is provided that includes a radio frequency circuit configured to receive and transmit radio frequency signals. The communication device further includes a processing circuit configured to process network information. The communication device further includes a memory circuit configured to transmit a first network information to the processing circuit. The communication device further includes a subscriber identity module configured to transmit a second network information to the processing circuit. The processing circuit is configured to select a first network based on the first network information and to register a communication device information at a second network based on the second network information.
