ATTENTION COMMANDS FOR MULTI-SUBSCRIBER IDENTITY MODULE DEVICES

This abstract first appeared for US patent application 18705297 titled 'ATTENTION COMMANDS FOR MULTI-SUBSCRIBER IDENTITY MODULE DEVICES

Original Abstract Submitted

Techniques for multi-universal subscriber identity module (MUSIM) operation include generating, by a terminal equipment (TE) of a device, an attention (AT) command. The AT command indicates a value of a parameter related to MUSIM operation of the device, such as whether to release a Non-Access Stratum (NAS) connection associated with a particular USIM of the device, whether to reject or restrict paging associated with the particular USIM of the device, or a requested (or selected) IMSI offset associated with the particular USIM of the device. The AT command is communicated from the TE to a mobile terminal (MT) of the device through a terminal adapter (TA).
