Abstract
Techniques discussed herein can reduce RRC signaling messages, and various aspects can employ one or more of these sets of techniques. A first set of techniques can be employed to reduce RACH (Random Access Channel) requests from an RRC Idle State SIM (Subscriber Identity Module) of a UE in DSDS (Dual SIM Dual Standby) mode. A second set of techniques can be employed to reduce the number of RACH attempts to obtain NotBroadcasted (e.g., On Demand) SI(s) (System Information(s)) by a UE in response to a page message indicating SI modification.
Claims20
A baseband processor comprising processing circuitry configured to:
- determine, via a first Subscriber Identity Module (SIM) of a User Equipment (UE), at least one On Demand System Information (SI) to be requested for the first SIM, wherein the first SIM does not have an established Radio Resource Control (RRC) connection;
- and
- in response to determining the at least one On Demand SI to be requested for the first SIM, generate a request for the at least one On Demand SI via a second SIM in an RRC Connected state, wherein the first SIM and the second SIM are both associated with a common carrier.
A User Equipment (UE), comprising:
- first and second Subscriber Identity Modules (SIMs);
- and
- one or more processors configured to:
- determine, via the first SIM, at least one On Demand System Information (SI) to be requested for the first SIM, wherein the first SIM does not have an established Radio Resource Control (RRC) connection;
- and
- in response to determining the at least one On Demand SI to be requested for the first SIM, generate a request for the at least one On Demand SI via the second SIM in an RRC Connected state, wherein the first SIM and the second SIM are both associated with a common carrier.
A method, comprising:
- determining, via a first Subscriber Identity Module (SIM) of a User Equipment (UE), at least one On Demand System Information (SI) to be requested for the first SIM, wherein the first SIM does not have an established Radio Resource Control (RRC);
- and
- in response to determining the at least one On Demand SI to be requested for the first SIM, generating a request for the at least one On Demand SI via a second SIM of the UE, the second SIM in a RRC Connected state, wherein the first SIM and the second SIM are both associated with a common carrier.
