  • Patent number: 10841402
    Abstract: The invention relates to methods and devices for distributing data content in an Information Centric Networking (ICN) network. In an aspect of the invention, there is provided a method performed at a wireless communication device of distributing data content in an ICN network. The method comprises submitting a request to distribute the data content to an agent device in the ICN network assigned to distribute the data content on behalf of the wireless communication device, the request comprising an identifier associated with the wireless communication device, an identifier of the request configured to enable delivery of the request to the agent device via intermediate ICN nodes of the ICN network, and the content to be distributed.

  • Publication number: 20200337107
    Abstract: According to certain embodiments, a network node is operable to change a general packet radio service (GPRS) tunneling protocol (GTP) tunneling endpoint identifier (TEID) when a user equipment (UE) resumes a connection to a core network. The network node comprises processing circuitry operable to receive a resume request from a UE; determine that the UE was previously connected to the network node prior to the resume; obtain one or more GTP TEIDs that are different than GTP TEIDs that were used when the UE was previously connected to the network node; and transmit an indication of the one or more GTP TEIDs to the core network. Transmitting the indication to the core network may comprise a path switch procedure, a UE context resume procedure, or a radio access bearer modification procedure.

  • Patent number: 10805856
    Abstract: A central unit (300A) and a first distributed unit (300B) of a first network node (300) and methods therein, for handling a communication with a wireless device (302) in a wireless network. The central unit (300A) sends an indication to the first distributed unit (300B) to indicate whether a current procedure for the wireless device is an inter-central unit procedure or an intra-central unit procedure. The first distributed unit (300B) is thereby able to decide whether to send information about the communication to the central unit via a user plane or via a control plane, based on a reduced amount of signalling including the indication.

  • Publication number: 20200296570
    Abstract: Method performed by a first network node (111) for handling content in an Information-Centric Network (ICN). The first network node (111) operates in a wireless communications network (100). The first network node (111) obtains (502) an indication about one or more network nodes (130) where a request for a content by a wireless device (151) operating in the wireless communications network (100) is predicted to be received in one or more future time periods. The one or more network nodes (130) operate in the wireless communications network (100) supporting ICN. The first network node (111) then initiates instructing (503) at least a subset of the one or more network nodes (130) to obtain the content prior to the one or more future time periods. Also described are a second network node (112), a third network node (133), and the wireless device (151), for facilitating handling the content in the ICN.

  • Patent number: 10708828
    Abstract: An access node (20) of a cellular network receives an information centric networking request of a user equipment (10) for a data object. The access node forwards the information centric networking request to a local gateway (30) associated with the access node (20). The local gateway (30) maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (30). In response to the user equipment (10) moving from a coverage area of the access node (20) to a coverage area of a further access node (21), the access node (20) and the further access node (21) perform a handover procedure. The further access node (21) is associated with a further local gateway (31) maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (31).

  • Publication number: 20180352602
    Abstract: An access node of the cellular network determines a correlation of an identifier of a user equipment with an entry of a Pending Interest Table maintained by an Information Centric Networking node. The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request at the Information Centric Networking node. Based on the correlation, the access node controls a connection of the user equipment with the cellular network. This may involve deciding whether to release the user equipment to idle mode or paging of the user equipment.
