A method performed by a network entity includes receiving a first instruction element (IE) indicating an identity of a wireless device and receiving a second IE indicating an action to buffer data intended for the wireless device, buffering the data intended for the wireless device, receiving a third IE indicating the identity of the wireless device and receiving a fourth IE indicating an action to stop buffering data and release the buffered data intended for the wireless device. The network entity then may transmit at least a portion of the buffered data to the wireless device.

Extended 5G local area network interworking with a home network and change of access network for 5G LAN connected devices

A client application running on a WTRU is configured to communicate data traffic over a TCP session with an MPTCP stack running on the WTRU. The data traffic is exchanged with a server application over a first MPTCP sub-flow with a first mobile edge (ME) host device. The WTRU is anchored to a second ME anchor node. The WTRU receives a first message from a second ME host device indicating that the WTRU should join a second MPTCP sub-flow with the second ME host device. The WTRU joins the second MPTCP sub-flow, responsive to the first message, wherein the second sub-flow is configured not to exchange data traffic. The WTRU receives a second message from the second ME host device configuring the second MPTCP sub-flow to exchange data traffic. The WTRU exchanges the data traffic with the server application over the second MPTCP sub-flow with the second ME host device.

Application mobility based on enhanced MPTCP

A wireless transmit/receive unit, WTRU, connects to a first AP, receives domain identifiers, requests corresponding descriptors and receives a list of descriptors. An application on the WTRU requests a list of domains and attributes corresponding to service names or service sets, which is returned by the WTRU. The application selects one or more domains for communications, the WTRU selects corresponding network resources and the application connects to local services. After moving to a new location, the WTRU connects to a second AP and receives a second set of domain identifiers, selects the one matching the request from the application and provides these to the application that, with the aid of the WTRU connects to local services.

Methods and devices for handling virtual domains

A method for setting up a multiple radio access technology (multi-RAT) device-to-device (D2D) communication is disclosed. An application function (AF) in a wireless transmit/receive unit (WTRU) may identify a group of multiple radio access technology (multi-RAT) capable WTRUs to a policy control function (PCF), wherein one or more multi-RAT capable WTRUs of the group of multi-RAT capable WTRUs register as having enhanced device-to-device (ED2D) functionality. The AF may select a multi-RAT capable WTRU from the group of multi-RAT capable WTRUs having ED2D functionality, as a relay for extended D2D operation. The device with ED2D function will act as Relay for ED2D (RED2D). The PCF may then reconfigure the RED2D with group related information. The RED2D may then configure D2D communication among the group of multi-RAT capable WTRUs.

Multi rat D2D, extending D2D to include 3GPP and other non-3GPP rat / devices

A WTRU may perform cERFs. A method may include any of: transmitting, to a nEAR, a signal requesting an IP address identifying (e.g., associated with) a DNS server associated with the WTRU; applying, by the WTRU, any of EI record rules for the identified DNS server, or updating EI records with the IP address identifying the DNS server; transmitting, to a DNS server, a DNS query associated with a FQDN; receiving, in response to the DNS query, FQDN resolution from the DNS server; on condition that a mobility event of the WTRU occurs, transmitting, to the nEAR, a signal requesting information for updating the EI records of the WTRU; and applying, by the WTRU, any of the updated EI record rules in order to perform any of: (1) redirecting application session traffic to provides session continuity for the WTRU, and (2) breaking any number of application sessions.

Methods, apparatus, and system for edge resolution function

Method, systems, and devices for transparent relocatable application instance deployment are described. A method performed by a Wireless Transmit/Receive Unit may comprise transmitting, to a Multi-access Edge Computing (MEC) system, a first message including a request to deploy the relocatable application instance at a target. The method may comprise receiving a second message including an indication to establish communication with the application instance and a Transparent Instance Relocation Session Identifier (TIRSI) and establishing, based on the second message, communication with the relocatable application instance at the target. The method may comprise transmitting a third message including a request for relocation of the application instance to another target. The method may comprise receiving a fourth message including an indication to establish communication with a relocated application instance at the another target and the TIRSI and establishing, based on the fourth message, communication with the relocated application instance at the another target.

Transparent relocation of MEC application instances between 5G devices and MEC hosts

Methods, apparatus, systems, architectures and interfaces for a wireless transmit receive unit (WTRU) performing a client-side edge resolution function (cERF) are provided. A method may include any of: determining a fully qualified domain name (FQDN) associated with a domain name server (DNS) request of an application associated with the WTRU; if the FQDN is associated with a valid edge instance (EI) record, selecting an EI for resolving the FQDN to an IP address; if the FQDN is not associated with a valid EI record: (1) transmitting a DNS query to a DNS server, (2) receiving an IP address associated with a selected EI to which the FQDN is resolved, and (3) updating the EI record with the IP address and the FQDN; and generating a traffic steering rule to re-direct uplink traffic associated with the application to the selected EI.

Methods, devices, and systems for third party edge cloud service providers (CSPs) to provide edge computing services to network service providers. The edge computing service is initialized in a network. Network information services of the network are discovered. A location of a cloud resource in the network may be dynamically changed. User plane traffic is steered toward the location of the cloud resource. In some embodiments, initializing the edge computing service includes transmitting an identity of a valid user and a data network name to a network function virtualization management and organization system, or transmitting a user subscription list to a network exposure function. In some embodiments, dynamically changing the location of a cloud resource and steering user plane traffic toward the location of the cloud resource includes determining a number of users of an edge application at a location, and a network requirement of the edge application.

Enhanced NEF function, MEC and 5G integration

Systems and methods for using a communication system in a spectrum are provided. For example, a random access or RACH procedure may be performed where the random access or RACH procedure may be configured to reduce secondary interference and/or to be used in a pixel-based environment. The random access or RACH procedure may include selecting a RACH preamble; sending a RACH preamble and/or format information; determining a transmission power of the RACH preamble and/or the format information; determining a random access radio network temporary identifier (RA-RNTI) and preamble ID associated with the RACH preamble; and/or selecting a physical RACH (PRACH).

Random access in dynamic and shared spectrums

Systems, methods, and instrumentalities are disclosed for media caching proxy techniques (e.g., applications) that enable caching of multimedia content delivered, for example, using the Dynamic Adaptive Streaming over HTTP (DASH) protocol. A request may be received from a client for a media presentation description (MPD) file relating to media content. The media content may comprise a plurality of media segments. An MPD file may be received from cache. A subset of the plurality of media segments of the media content stored within the cache may be determined. An available bandwidth on a backhaul link may be determined. A dynamic MPD file may be generated based on the MPD file, the subset of the plurality of media segments of the media content that is stored within the cache of the middle box platform, and/or the available bandwidth on the backhaul link. The dynamic MPD file may be transmitted to the client.

Dash caching proxy application

Embodiments include methods, systems, and apparatuses for content delivery using shared caching, and more specifically, a browser cache extension (BCE) between a local browser cache and a remote cache located on an edge server. In an embodiment, a remote BCE function on the edge server may create a shared cache folder containing a remote cache and an remote cache index file. A local BCE function in the local browser may be able to access the shared cache folder via a network file system (NFS) protocol. The local BCE function may merge the remote index file with a local index file from the local browser and retrieve the remote cache at the local browser.

Methods and apparatus for content delivery via browser cache extension

A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

Method and apparatus for operating supplementary cells in licensed exempt spectrum

Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.
