  • Publication number: 20190150219
    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.

  • Publication number: 20160255535
    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.

  • Patent number: 8848640
    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.

  • Publication number: 20140153489
    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.

  • Patent number: 7054291
    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.

  • Patent number: 6920116
    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.

  • Patent number: 6876640
    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.

  • Publication number: 20020167909
    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.
