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： For traffic offload via a local network, a MME may obtain from a HSS, subscription data including SIPTO related permissions defined on APN basis that indicate SIPTO prohibited, indicate SIPTO allowed excluding SIPTO via Local Network (SIPTO@LN), and/or indicate SIPTO allowed including SIPTO@LN. Then, the MME may obtain information about one or more local Gateways (GWs) capable of offloading selected traffic, such information indicating which of the one or more local GWs provides access to which Packet Data Networks (PDNs), with each PDN being identified by its associated APN. Finally, the MME may process PDN connections and/or PDN disconnections in order to support offloading of the selected traffic. The counterpart UE includes the appropriate means of hardware and/or software that is configured to support and perform SIPTO@LN.

摘要： An apparatus and system for onboarding network behavior based on the type of UE and identification information are described. The identification information, if provided by the UE, is provided either during an initial registration procedure or a configured PDU session establishment procedure and includes one or both of an SO-SNPN and provisioning server identity. The UE, if identification information is provided by an SMF, overwrites the default identification information stored in the UE and performs provisioning server discovery on a provisioning server identity in the identification information. If the UE does not store provisioning server identification, the UE constructs a well-defined FQDN to perform provisioning server discovery.

摘要： When a UE in an LTE system enters the RRC_IDLE state, only the S5/S8 EPS bearer context is retained, and the S1-U, S1-AP and radio bearers are released. These bearers have to be re-established on per UE basis when the UE returns to RRC_CONNECTED state. A number of UE applications may send small data frequently, which causes the UE to toggle between IDLE and CONNECTED states. This leads to a great deal of signaling overhead as the radio bearer and the S1-U bearer must be frequently re-established as the UE transitions between IDLE to CONNECTED states. Described herein are methods and systems that provide an always-on S1-U bearer to reduce this signaling overhead.
摘要翻译： 当LTE系统中的UE进入RRC_IDLE状态时，仅保留S5 / S8 EPS承载上下文，并释放S1-U，S1-AP和无线承载。 当UE返回到RRC_CONNECTED状态时，必须在每个UE的基础上重新建立这些承载。 许多UE应用可以频繁地发送小数据，这导致UE在空闲和连接状态之间切换。 这导致大量的信令开销，因为当UE在空闲到连接状态之间转换时，无线电承载和S1-U承载必须频繁重新建立。 这里描述了提供始终在线的S1-U承载以减少该信令开销的方法和系统。

摘要： Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

摘要： Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB-CU and a gNB-DU. A first paging message for paging of the UE may be received at the gNB-CU from an access management function (AMF) entity. The first paging message may include: a paging identity of the UE; and a paging origin information element (IE) that indicates whether the paging of the UE is originated due to a protocol data unit (PDU) session from non-3GPP access. A second paging message to page the UE may be transmitted from the gNB-DU to the UE. The second paging message may include: the paging identity of the UE; and an access type parameter that indicates whether the paging of the UE is originated due to the PDU session from the non-3GPP access.
