    摘要: Embodiments for providing network-assisted to direct device discovery switch are generally described herein. In some embodiments, location information is received at an evolved packet core (EPC) from at least a first and a second user equipment (UE). A network-assisted device-to-device (D2D) request is received from the first UE for establishing a D2D wireless connection with the second UE. Proximity of the first UE and the second UE are monitored. Before detecting the second UE being in proximity to the first UE, direct discovery is determined to be more resource efficient than continuing to provide network-assisted D2D discovery. An indication is provided to the first UE and the second UE to perform direct discovery based on information provided in the indication.

    摘要: An apparatus used in a UE includes processing circuitry and memory. To configure the UE for a DNS resolution, the processing circuitry is to encode UL data for transmission to a first EAS via a first data path. The first data path includes a first UL CL UPF and a first PSA. A NAS SM message received from an SMF node is decoded. The NAS SM message includes an EAS rediscovery indication and a list of FQDNs associated with the first EAS. A DNS resolution procedure with a DNS server is performed in response to the EAS rediscovery indication, to obtain an IP address of a second EAS. The DNS resolution procedure is based on the list of FQDNs, and a second data path to the second EAS is established based on the IP address.

    摘要: In order to perform SIPTO@LN for PDN connections, MME performs: receiving, from a HeNB, information about one or more GWs, said information comprising an IP address of each local GW and at least one among APN-specific information for said one or more local GWs and/or a non-APN-specific indication for said one or more local GWs; initiating, based on subscription data and the received information about a particular local GW among said one or more local GWs, deactivation of one or more PDN connections by sending to UE a NAS Deactivate Bearer Request message indicating that reactivation is required for said one or more PDN connections; and selecting, in response to a reactivation attempt by the UE and based on said subscription data and the received information about said particular local GW, said particular local GW to allow SIPTO@LN to be performed via said particular local GW.
