5G New Radio - Avoiding Redundant AS Security Checks
First Claim
1. A user equipment device (UE), comprising:
- at least one antenna;
at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one radio access technology (RAT);
one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform voice and/or data communications;
wherein the one or more processors are configured to cause the UE to;
determine that an on-demand system information block (SIB) request is pending transmission;
buffer, in response to determining that a connection establishment procedure will be initiated within a specified time period, the on-demand SIB request for at least the specified time period;
perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security; and
in response to confirming connection security, use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature.

Abstract
Apparatuses, systems, and methods for a wireless device to perform methods for improvements to security checks in a fifth generation (5G) New Radio (NR) network, including mechanisms to avoid redundant access stratum (AS) security checks. The wireless device may determine that an on-demand system information block (SIB) request is pending transmission and may buffer the on-demand SIB in response to determining that a connection establishment procedure will be initiated within a specified time period. The wireless device may then perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security. Further, in response to confirming connection security, the wireless device may use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature.

10. An apparatus, comprising:
-
a memory; and one or more processors in communication with the memory, wherein the one or more processors are configured to; determine that an on-demand system information block (SIB) request is pending transmission; buffer, in response to determining that a connection establishment procedure will be initiated within a specified time period, the on-demand SIB request for at least the specified time period; generate instructions to perform a unified security procedure for the on-demand SIB request and the connection establishment procedure, including confirming connection security; and in response to confirming connection security, use an on-demand SIB received from the network without confirming a corresponding on-demand SIB signature. - View Dependent Claims (11, 12, 13, 14, 15)

16. A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a network node to:
- receive, from a user equipment device (UE), an indication of a unified security procedure, wherein the unified security procedure includes an establish connection request and an on-demand system information block (SIB) request; and
perform at least one of; delaying transmission of an on-demand SIB response until completion of security confirmation of the connection request;
ortransmitting an on-demand SIB response without a corresponding on-demand SIB signature, thereby triggering the UE to confirm security via the connection request. - View Dependent Claims (17, 18, 19, 20)
- receive, from a user equipment device (UE), an indication of a unified security procedure, wherein the unified security procedure includes an establish connection request and an on-demand system information block (SIB) request; and
