Abstract

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).

First claim

1 . A device, comprising:
processing circuitry comprising a terminal equipment (TE), a mobile terminal (MT) and a terminal adapter (TA), the processing circuitry configured to: generate, by the TE, an attention (AT) command, wherein the AT command indicates a value of a parameter related to multi-universal subscriber identity module (MUSIM) operation of the device; and communicate the AT command from the TE to the MT through the TA; and memory configured to store data related to the value of the parameter related to MUSIM operation of the device.

2 . The device of claim 1 , wherein the parameter comprises a Non-Access Stratum (NAS) connection release parameter, and wherein the value of the NAS connection release parameter indicates whether to release a NAS connection between the device and a network node.

3 . The device of claim 2 , wherein the MT is configured to indicate to the network node whether to release the NAS connection between the device and the network node based on the value of the NAS connection release parameter.

4 . The device of claim 1 , wherein the parameter comprises a paging rejection parameter, and wherein the value of the paging rejection parameter indicates whether to reject paging of the device by a network node.

5 . The device of claim 4 , wherein the MT is configured to indicate to the network node whether to the device has rejected paging based on the value of the paging rejection parameter.

6 . The device of claim 1 , wherein the parameter comprises a paging restriction parameter, and wherein the value of the paging restriction parameter indicates whether paging is not restricted, all paging is restricted, all paging is restricted except for voice service, all paging is restricted except for a specified public data network (PDN) connection or protocol data unit (PUD) session, or all paging is restricted except for voice services and the specified PDN connection or PDU session.

7 . The device of claim 6 , wherein a value of a one or more other paging restriction parameters indicate the specified PDN connection or PDU session.

8 . The device of claim 6 , wherein the MT is configured to indicate to a network node one or more paging restrictions based on the value of the paging restriction parameter.

9 . The device of claim 1 , wherein the parameter comprises a paging collision parameter, and wherein the value of the paging collision parameter indicates whether to present an unsolicited return code in response to a change in an international mobile subscriber identity (IMSI) offset associated with the device.

10 . The device of claim 1 , wherein the parameter comprises a paging collision parameter, and wherein the value of the paging collision parameter indicates a requested IMSI offset for the device or a selected IMSI offset for the device.

11 . The device of claim 1 , wherein the MT is configured to transmit, to a network node, a message based on the value of the parameter during an Evolved Packet System Mobility Management (EMM) Tracking Area Update or Service Request procedure, or during a 5G Mobility Management (5GMM) Registration Request or Service Request procedure.

12 . The device of claim 1 , wherein the processing circuitry is configured to communicate an AT command response from the MT to the TE through the TA in response to the AT command.

13 . A method, comprising:
generating, by a terminal equipment (TE) of a device, an attention (AT) command, wherein the AT command indicates a value of a parameter related to multi-universal subscriber identity module (MUSIM) operation of the device; and communicating the AT command from the TE to a mobile terminal (MT) of the device through a terminal adapter (TA).

14 . The method of claim 13 , wherein the parameter comprises a Non-Access Stratum (NAS) connection release parameter, and the value of the NAS connection release parameter indicates whether to release a NAS connection between the device and a network node, or wherein the parameter comprises a paging rejection parameter, and the value of the paging rejection parameter indicates whether to reject paging of the device by a network node.

15 . The method of claim 13 , wherein the parameter comprises a paging restriction parameter, and wherein the value of the paging restriction parameter indicates whether paging is not restricted, all paging is restricted, all paging is restricted except for voice service, all paging is restricted except for a specified public data network (PDN) connection or protocol data unit (PUD) session, all paging is restricted except for voice services and the specified PDN connection or PDU session.

16 . The method of claim 13 , wherein the parameter comprises a paging collision parameter, and wherein the value of the paging collision parameter indicates whether to present an unsolicited return code in response to a change in an international mobile subscriber identity (IMSI) offset associated with the device, indicates a requested IMSI offset for the device, or indicates a selected IMSI offset for the device.

17 . At least one non-transitory computer-readable medium storing instructions executable by at least one processor to perform operations comprising:
generating, by a terminal equipment (TE) of a device, an attention (AT) command, wherein the AT command indicates a value of a parameter related to multi-universal subscriber identity module (MUSIM) operation of the device; and communicating the AT command from the TE to a mobile terminal (MT) of the device through a terminal adapter (TA).

18 . The at least one non-transitory computer-readable medium of claim 17 , wherein the parameter comprises a Non-Access Stratum (NAS) connection release parameter, and the value of the NAS connection release parameter indicates whether to release a NAS connection between the device and a network node, or wherein the parameter comprises a paging rejection parameter, and the value of the paging rejection parameter indicates whether to reject paging of the device by a network node.

19 . The at least one non-transitory computer-readable medium of claim 17 , wherein the parameter comprises a paging restriction parameter, and wherein the value of the paging restriction parameter indicates whether paging is not restricted, all paging is restricted, all paging is restricted except for voice service, all paging is restricted except for a specified public data network (PDN) connection or protocol data unit (PUD) session, all paging is restricted except for voice services and the specified PDN connection or PDU session.

20 . The at least one non-transitory computer-readable medium of claim 17 , wherein the parameter comprises a paging collision parameter, and wherein the value of the paging collision parameter indicates whether to present an unsolicited return code in response to a change in an international mobile subscriber identity (IMSI) offset associated with the device, indicates a requested IMSI offset for the device, or indicates a selected IMSI offset for the device.
