Abstract: Various embodiments of apparatus, systems and/or methods are described for providing cell reselection from a visiting PLMN to home PLMN in scenarios where the UE is camped to a visiting cell with an Equivalent HPLMN identity. The method may include cell reselection from one radio frequency broadcasting the Equivalent HPLMN identity to another preferred radio frequency that broadcasts only the visiting PLMN identity by leveraging frequency selection priority, and subsequent cell reselection from the visiting PLMN identity with the visiting PLMN cell to the home PLMN identity with the home PLMN cell by using high priority home PLMN identity search. The method provides a means to allow the UE to quickly come back to home PLMN when entering home coverage, otherwise the UE would have to move out of the coverage of the Equivalent HPLMN identity from the border cells of the visiting PLMN by radio refrequency rescan and selection.

Abstract: Various embodiments of apparatus, systems and/or methods are described for processing SMS messages using a gateway server (IP-SM-GW). The IP-SM-GW includes a processor, multiple interfaces, and at least one module. These interfaces are configured to receive a short message service (SMS) message from one of a plurality of different networks comprising LTE, 2G/3G and 5G. The module is configured to determine which of the networks the SMS message originated from; query the subscriber database based on the UE identifier in the MO SMS message; validate the SMS message; and in response to the result of validating the SMS message, sending the SMS message to a short message service center server (SMSC) for delivery or rejecting the SMS message for deposit. The IP-SM-GW also is configured to select and send the SMS message to the proper domain.
