Secure paging for service prioritization

An apparatus for wireless communication, comprising:

• an interface configured to:
• receive, from a base station (BS), during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU), information indicating a mapping between different paging information and indices associated with the different paging information, and
• receive, from the BS, a paging message comprising encrypted paging information;
• and
• a processing system configured to:
• decrypt the encrypted paging information to identify an index included in the encrypted paging information,
• determine paging information corresponding to the index based on the mapping, and
• determine whether to communicate with the BS based on the paging information.

A method for wireless communication at an apparatus of a base station (BS), the method comprising:

• transmitting, to a user equipment (UE), during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU), information indicating a mapping between different paging information and indices associated with the different paging information;
• encrypting paging information based on the information;
• and
• transmitting, to one of the UE or another BS for transmission to the UE, a paging message comprising the encrypted paging information.

An apparatus for wireless communication, comprising:

• a processing system configured to encrypt paging information based on information indicating a mapping between different paging information and indices associated with the different paging information;
• and
• an interface configured to:
• output, for transmission to one of a user equipment (UE) or a base station to transmit to the UE, during at least one of a registration procedure or a radio access network (RAN)-based Notification Area Update (RNAU), the information indicating the mapping, and
• output, for transmission to the one of the UE or the base station to transmit to the UE, a paging message comprising the encrypted paging information.
