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.

Claims

1. A mobility management entity (MME) comprising:

processing circuitry; and

memory, the processing circuitry configured to;

provide signaling for transmission to a user equipment (UE) to activate idle mode signal reduction (ISR) for subsequent use during inter-RAT cell re-selection while the UE is in idle mode;

receive signaling indicating that packet switched (PS) services with the UE have been suspended if the UE performed an inter-RAT cell reselection in accordance with ISR when ISR is active and the UE has left a E-UTRAN cell and established a circuit-switched (CS) radio signalling connection with a non-EUTRAN cell, the signalling received while the UE has a signaling connection within the non-E-UTRAN cell;

receive signaling indicating that the UE has initiated a tracking area update (TAU) procedure when the ISR is activated to resume the PS services when the UE returns to the E-UTRAN cell and the CS signalling connection is terminated; and

based on an unsuccessful resumption of PS services, receive signaling from the UE indicating that the UE has initiated another TAU procedure when the ISR is deactivated to resume PS services.

2. The MME of claim 1, wherein the MME is further configured to provide signaling to a serving gateway (S-GW) to resume suspended bearers subsequent to initiation of the another TAU procedure.

3. The MME of claim 2 wherein the MME is further configured to provide signaling to at least one packet data network gateway (P-GW) to resume suspended bearers.

4. The MME of claim 2 wherein the MME is configured to provide signaling to the UE to suspend the PS services when the ISR is activated before a circuit-switched fallback (CSFB) call.

5. The MME of claim 1, wherein the signaling to activate ISR is provided in a TAU accept message.

6. The MME of claim 1, wherein the MME is connected to the S-GW via an S11 link.

7. The MME of claim 1, wherein the MME includes an internal S10 link and an S6a link to a High Speed Serial (HSS) interface node.

8. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a mobility management entity (MME) to configure the MME to:

provide signaling for transmission to a user equipment (UE) to activate idle mode signal reduction (ISR) for subsequent use during inter-RAT cell re-selection while the UE is in idle mode;

receive signaling indicating that packet switched (PS) services with the UE have been suspended if the UE performed an inter-RAT cell reselection in accordance with ISR when ISR is active and the UE has left a E-UTRAN cell and established a circuit-switched (CS) radio signalling connection with a non-EUTRAN cell, the signalling received while the UE has a signaling connection within the non-E-UTRAN cell;

receive signaling indicating that the UE has initiated a tracking area update (TAU) procedure when the ISR is activated to resume the PS services when the UE returns to the E-UTRAN cell and the CS signalling connection is terminated; and

based on an unsuccessful resumption of PS services, receive signaling from the UE indicating that the UE has initiated another TAU procedure when the ISR is deactivated to resume PS services.

9. The non-transitory computer-readable storage medium of claim 8, wherein the instructions further configure the MME to provide signaling to a serving gateway (S-GW) to resume suspended bearers subsequent to initiation of the another TAU procedure.

10. The non-transitory computer-readable storage medium of claim 9, wherein the instructions further configure the MME to provide signaling to at least one packet data network gateway (P-GW) to resume suspended bearers.

11. The non-transitory computer-readable storage medium of claim 9, wherein the instructions further configure the MME to provide signaling to the UE to suspend the PS services when the ISR is activated before a circuit-switched fallback (CSFB) call.

12. The non-transitory computer-readable storage medium of claim 8, wherein the signaling to activate ISR is provided in a TAU accept message.
