1. A user equipment (UE) configured for inter-RAT mobility, the UE comprising:
- a transceiver coupled to a processor, the transceiver and processor, configured to;
receive signaling to activate idle mode signal reduction (1SR) for subsequent use during inter-RAT cell re-selection while the UE is in idle mode;
perform inter-RAT cell reselection in accordance with ISR when ISR is activated, the inter-RAT cell reselection to establish a circuit-switched (CS) radio signaling connection within a target cell when the target cell is a non-E-UTRAN cell;
transmit signaling to suspend packet switched (PS) services while the UE has a signaling connection within a non-E-UTRAN cell;
transmit signaling to initiate a tracking area update (TAU) procedure when ISR is activated to resume PS services when the UE returns to a E-UTRAN cell; and
based on an unsuccessful resumption of PS services, deactivate ISR after returning to the E-UTRAN cell prior to initiating another TAU procedure to resume PS services.

Abstract
This disclosure relates generally to resuming packet services in a mobile network. A device, method, and/or system may include switching, with user equipment, from communicating with a first radio access network to communicating with a second radio access network, setting, with a processor of the user equipment, a register of the user equipment to initiate packet services with the first radio access network, and transmitting, with the user equipment, a request to a core network node of the first radio access network to resume communications with the first radio access network based, at least in part, on the register.

16. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE) to configure the UE to perform operations for inter-RAT cell reselection, the operations to configure the one or more processors to configure the UE to:
-
receive signaling to activate idle mode signal reduction (ISR) for subsequent use during inter-RAT cell re-selection while the UE is in idle mode; perform inter-RAT cell reselection in accordance with ISR when ISR is activated, the inter-RAT cell reselection to establish a circuit-switched (CS) radio signaling connection within a target cell when the target cell is a non-E-UTRAN cell; transmit signaling to suspend packet switched (PS) services while the UE has a signaling connection within a non-E-UTRAN cell; transmit signaling to initiate a tracking area update (TAU) procedure when ISR is activated to resume PS services when the UE returns to a E-UTRAN cell; and based on an unsuccessful resumption of PS services, deactivate ISR after returning to the E-UTRAN cell prior to initiating another TAU procedure to resume PS services. - View Dependent Claims (17, 18)
