Abstract: A method and a system are disclosed for providing session continuity in a 5G system. A wireless transmit receive unit (WTRU) may receive, from a session management function (SMF), a first Non-Access Stratum (NAS) message indicating a Packet Data Unit (PDU) session re-establishment. Upon receiving the first NAS message, the WTRU may determine an old PDU session ID based on the NAS message and generate a new PDU session ID. The WTRU may transmit a second NAS message indicating a PDU session establishment request. The second NAS message may include the old and new PDU session IDs. Upon receiving the PDU session establishment request, the SMF may determine that the old PDU session ID is associated with an existing PDU session for which the PDU session re-establishment is requested. The SMF may also determine that the new PDU session ID is associated with a new PDU session to be established.

Abstract: 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.

Abstract: Methods, apparatus, systems, devices, and computer program products directed to enabling federation 200 of multiple independent networks 204A, 204B, 204C, 204D through hash-routing based peering (HRP) and/or summary-routing based peering (SRP) are provided. Pursuant to new methodologies and/or technologies provided herein the multiple independent networks self-organize, or otherwise assemble, as a federation of network peers. The network peers 204A, 204B, 204C, 204D cooperate to pool and/or merge resources to make available for the federation 200 a population of content objects. As members of the federation, each of the network peers undertakes responsibility for making available to other network peers a share of the population. The multiple independent networks establish connectivity and federate using an HRP protocol. Pursuant to the HRP protocol, the network peers allocate amongst themselves respective key ranges within a hash-value space of a hash function.

Abstract: Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.

Abstract: Systems, methods, and instrumentalities are disclosed to implement hierarchical policies for local networks. In one representative method, a first local node may establish a dedicated local IP access (LIPA) packet data network (PDN) connection for a local service provided via a local network. The method may include responsive to a request for access to the local service, the first local node receiving a quality of service (QoS) requirement for the requested local service; sending, to a second local node, a dedicated bearer request with a specified QoS level based on a global policy and network-information specific to the local network; and receiving a dedicated bearer response with the specified QoS level.

Abstract: Systems and methods for providing a converged gateway (CGW) may be disclosed. A policy may be by the CGW to make routing decisions (e.g. segregation and/or aggregation of flows or traffic associated with data) for various interfaces and/or radio access technologies (RATs) that may be included in a LAN, device, and/or communication system. The policy may be locally stored within the CGW. Dynamic flow management, load balancing, offloading, PDF context establishment, prioritization, detection of devices, and the like may also be provided and/or implemented in the CG W and may be used to route flows and/or traffic associated with data.

Abstract: A method and apparatus for bandwidth aggregation for an Internet protocol (IP) flow are disclosed. A sender may split IP packets on a single IP flow, and transmit the IP packets to a receiver via at least two interfaces. The sender splitting the IP packets over multiple interfaces may not send any signaling to the receiver. Alternatively, the sender may send information to the receiver for configuring distribution of the IP packets over multiple interfaces. The information may be carried on a binding update message, a binding acknowledgement message, or a binding refresh request message. The IP packets may be split and transmitted by a logical interface that sits between an IP layer and a layer 2, or by a bandwidth aggregation (BWA) middleware located between a transmission control protocol (TCP) layer and an IP layer.

Abstract: User equipment (UE) may include dual mode devices that enable two different radio access technologies (RATs) for connection to wireless communication networks. Recently, these RATs have been used for message splitting in which a message is split into two packet flows, for example, that may enable increased throughput to the (UE). Dynamic mobility management may be provided for the UE by allowing a converged gateway (CGW) to discover the UE. For example, the CGW may identify the UE in communication a first CGW that may be within a first subnet. The CGW may store the identity of the WTRU in the memory. The CGW may transmit the identity of the UE to a second CGW that may be in communication with a second subnet.

Abstract: Communication nodes, systems and methods are described which provide offload processing capabilities. Tasks can be offloaded from a host element to an offload processing element. Incoming data streams can have their associated Layer 3/Layer transportation protocol stacks terminated. Data can be repackaged and routed using an internal, offload protocol which also preserves L3 and/or L4 information.

Abstract: An abbreviated point-to-point protocol (PPP) negotiation in a wireless communication system is performed between a first peer, such as a mobile station, and a second peer, such as a packet data service node. The first peer sends a link control protocol option designated option X to the second peer. The option X identifies a user profile that includes at least one pre-negotiated point-to-point protocol parameter. If the second peer supports the user profile and the at least one parameter is acceptable to the second peer, the second peer acknowledges that the user profile is acceptable to the second peer. In response, the first peer acknowledges that the user profile is acceptable to the first peer. In response to both peers acknowledging that the user profile is acceptable, each of the peers sets a respective state machine in accordance with the user profile.

Abstract: A system and method in a General Packet Radio Service (GPRS) network for automatically configuring Network Service Entity Identifiers (NSEIs) in a Base Station System (BSS) and a Serving GPRS Support Node (SGSN) when the BSS is reconfigured. The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP. Whenever a new Network Service Entity (NSE) is added to an existing BSS, or a new BSS is added to the network, the BSS automatically sends a modified Network Service (NS?)-Reset message to the SGSN requesting an NSEI. The SGSN dynamically allocates a free NSEI from a pool of NSEIs and sends it to the BSS. When an NSE is removed from the BSS, the BSS automatically sends a modified NS?-Reset message to the SGSN to free an NSEI. The SGSN de-allocates the NSEI, and returns the NSEI to the pool of free NSEIs.

Abstract: A Point-to-Point protocol (PPP) session with a mobile station is initiated in a wireless communication system. The session is negotiated by a first Packet Data Service Node (PDSN), which creates a PPP context for the mobile station for the session. The PPP context is added to a PPP register, which stores the PPP context indexed by the International Mobile Station Identifier (IMSI) of the mobile station for later retrieval if needed. In the event the mobile station is handed over to a second PDSN, such as when the mobile station roams and the first PDSN cannot be reached, the second PDSN retrieves the stored PPP context using the IMSI of the mobile station so that the PPP session can be resumed without a need for a complete renegotiation of the PPP context. The PDSNs further periodically re-register or update the PPP context on the PPP register.

Abstract: A system and method in a General Packet Radio Service (GPRS) network for interfacing a Base Station System (BSS) and a Serving GPRS Support Node (SGSN). A protocol stack in the BSS and the SGSN includes a User Datagram Protocol (UDP) layer over an Internet Protocol (IP) layer. Data packets are transmitted between functional entities in the SGSN and the BSS over a connectionless IP network. The protocol stack includes a Base Station System GPRS Protocol (BSSGP) protocol layer that provides radio-related, Quality-of-Service (QoS), and routing information that is required to transmit user data between the BSS and the SGSN. The stack also includes a modified Network Services (NS′) layer which is divided into an upper NS′-Network Service Control (NS′-NSC) sub-layer and a lower NS′-Sub-Network Service (NS′-SNS) sub-layer. The NS′-NSC sub-layer maps to the BSSGP layer and manages fictional entities therein.

Abstract: The present invention relates to a system, a method and a service node for providing a pre-paid service to a mobile station for data transmission in a packet data cellular telecommunication network. A connection is established between the mobile station and the service node in the packet data cellular telecommunication network. Upon establishment of the connection, at least one pre-paid connection limit parameter is obtained from a subscriber account database. The at least one pre-paid connection limit parameter is indicative of a limit at which the connection must be terminated. Then, the service node monitors the connection to determine whether the data transmission exceeds the at least one pre-paid connection limit parameter. If the data transmission exceeds the at least one pre-paid connection limit parameter, the connection is terminated.
