Abstract

Various embodiments include systems, wireless modules, and methods for local IP access packet data network release. Handover data can be received at a target wireless module as part of a user equipment handover operation. The user equipment can include an active packet data network session associated with a source local home network. A determination that the target wireless module is not in the source local home network can be made based on the handover data. The target wireless module can trigger deactivation of the packet data network session in response to the determination that the target wireless module is not in the source local home network.

Claims

1. A circuit-implemented wireless module comprising:

receiver circuitry configured to receive handover data as part of a user equipment (UE) handover operation, the UE including an active packet data network (PDN) session associated with a source local home network (LHN), wherein the part of the UE handover operation is at least one of a handover preparation operation or a handover completion operation, the handover completion operation occurring after the handover preparation operation, the handover preparation operation being at least one of a handover operation, an X2 application protocol (X2AP) handover request, an S1 application protocol (S1AP) handover request, or a 3GPP universal mobile telecommunications system (UMTS) relocation request, the handover completion operation being at least one of X2AP message or an S1AP message, the handover operation including a UE LHN-ID for the UE and a local IP access (LIPA) bearer for the PDN session; and

processor circuitry configured to;

determine that the wireless module is not in the source LHN based on the handover data, including determining that an LHN-ID of the wireless module is different than the UE LHN-ID; and

trigger deactivation of the PDN session in response to the determination that the wireless module is not in the source LHN, including omitting the LIPA bearer from an acknowledgment to the handover operation.

2. The wireless module of claim 1, wherein the acknowledgment is an X2AP handover request acknowledge when the handover operation is an X2AP handover request.

3. The wireless module of claim 1, wherein the acknowledgment is an S1AP handover request acknowledge when the handover operation is an S1AP handover request.

4. The wireless module of claim 1, wherein the acknowledgment is a UMTS relocation request acknowledge when the handover operation is a UMTS relocation request.

5. The wireless module of claim 1, wherein the acknowledgment is an S1AP path switch request when the handover operation is an X2AP message.

6. The wireless module of claim 1, wherein the acknowledgment is S1AP handover notify message or an S1AP forward relocation complete notification when the handover operation is an S1AP message.

7. The wireless module of claim 1, wherein the wireless modules is a home eNB (HeNB) in accordance with a 3GPP family of standards or a radio network controller (RNC) in accordance with a UMTS family of standards.

8. A method comprising:

receiving, at a target wireless module, handover data as part of a user equipment (UE) handover operation, the UE including an active packet data network (PDN) session associated with a source local home network (LHN), wherein the part of the UE handover operation is at least one of a handover preparation operation or a handover completion operation, the handover completion operation occurring after the handover preparation operation, the handover preparation operation being at least one of a handover operation, an X2 application protocol (X2AP) handover request, an S1 application protocol (S1AP) handover request, or a 3GPP universal mobile telecommunications system (UMTS) relocation request, the handover completion operation being at least one of X2AP message or an S1AP message, the handover operation including a UE LHN-ID for the UE and a local IP access (LIPA) bearer for the PDN session;

determining that the target wireless module is not in the source LHN based on the handover data including determining that an LHN-ID of the wireless module is different than the UE LHN-ID; and

triggering, by the target wireless module, deactivation of the PDN session in response to the determination that the target wireless module is not in the source LHN, including omitting the LIPA bearer from an acknowledgment to the handover operation.

9. The method of claim 8, wherein the acknowledgment is an X2AP handover request acknowledge when the handover operation is an X2AP handover request.

10. The method of claim 8, wherein the acknowledgment is an S1AP handover request acknowledge when the handover operation is an S1AP handover request.

11. The method of claim 8, wherein the acknowledgment is a UMTS relocation request acknowledge when the handover operation is a UMTS relocation request.

12. The method of claim 8, wherein the acknowledgment is an S1AP path switch request when the handover operation is an X2AP message.

13. The method of claim 8, wherein the acknowledgment is SLAP handover notify message or an S1AP forward relocation complete notification when the handover operation is an S1AP message.

15. A non-transitory machine-readable medium including instructions, which when executed by a wireless module, cause the wireless module to perform operations, the operations comprising:

receiving handover data as part of a user equipment (UE) handover operation, the UE including an active packet data network (PDN) session associated with a source local home network (LHN), wherein the part of the UE handover operation is at least one of a handover preparation operation or a handover completion operation, the handover completion operation occurring after the handover preparation operation, the handover preparation operation being at least one of a handover operation, an X2 application protocol (X2AP) handover request, an S1 application protocol (S1AP) handover request, or a 3GPP universal mobile telecommunications system (UMTS) relocation request, the handover completion operation being at least one of X2AP message or an S1AP message, the handover operation including a UE LHN-ID for the UE and a local IP access (LIPA) bearer for the PDN session;

determining that the wireless module is not in the source LHN based on the handover data including determining that an LHN-ID of the wireless module is different than the UE LHN-ID; and

triggering deactivation of the PDN session in response to the determination that the wireless module is not in the source LHN, including omitting the LIPA bearer from an acknowledgment to the handover operation.
