Abstract
Connection management techniques for wireless network mobility procedures are described. In one embodiment, for example, an evolved packet core (EPC) node may comprise a processor circuit to receive a notification of a mobility procedure for a user equipment (UE), determine whether to release a local gateway (L-GW)-provided packet data network (PDN) connection of the UE, and in response to a determination that the L-GW-provided PDN connection is to be released, send either a detach request message or a delete session request message to initiate a process for releasing the L-GW-provided PDN connection. Other embodiments are described and claimed.
Claims27
An evolved packet core (EPC) node, comprising:
- a processor circuit to receive a notification of a mobility procedure for a user equipment (UE), determine whether to release a local gateway (L-GW)-provided packet data network (PDN) connection of the UE, and in response to a determination that the L-GW-provided PDN connection is to be released, send either a detach request message or a delete session request message to initiate a process to release the L-GW-provided PDN connection.
A mobility management entity (MME), comprising:
- logic, at least a portion of which is in hardware, the logic to receive, during a mobility procedure for a user equipment (UE), a mobility procedure control message, determine to release a selected internet protocol traffic offload at local network (SIPTO@LN) packet data network (PDN) connection of the UE based on the mobility procedure control message, and following the mobility procedure, trigger a deactivation of the SIPTO@LN PDN connection.
At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed on a mobility management entity (MME), cause the MME to:
- receive a notification of a tracking area update (TAU) procedure for a user equipment (UE);
- during the TAU procedure, receive a context response message identifying a selected internet protocol traffic offload at local network (SIPTO@LN) packet data network (PDN) connection of the UE and identifying a local home network identifier (LHN-ID) for the UE;
- and
- determine whether to prompt a release of the SIPTO@LN PDN connection based on the LHN-ID.
(canceled)
A method, comprising:
- receiving, at a target mobility management entity (MME) for a handover of a user equipment (UE), a forward relocation request;
- determining, by a processor circuit, that a local gateway (L-GW)-provided packet data network (PDN) connection for the UE is to be disconnected based on the forward relocation request;
- and
- selecting a process for disconnecting the L-GW-provided PDN connection based on a determination of whether the L-GW-provided PDN connection comprises a lone PDN connection for the UE.
