Methods and device(s) () for managing Round Trip Time, RTT, associated with provision of a data flow () from a server device (), via a multi-access communication network (), to a client device (). Said device(s) () being communicatively connected to the multi-access communication network () that is configured to provide the data flow () to the client device () using a resource of the multi-access communication network () that is shared by multiple devices (--). The device(s) () initiates, in response to identification that the data flow () belongs to a certain type, introduction of an artificial delay in the RTT.

Methods and arrangements for managing round trip time associated with provision of a data flow via a multi-access communication network

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.

Correlation of user equipment identity to information centric networking request

A method and a device proxy for handling radio communication of content data from a data source to be played out on a media player of a wireless device in a wireless network. When detecting that a potential data class is available, the device proxy fetches segments of the content data from the data source over a potential data bearer dedicated for data of said potential data class. The potential data bearer is dedicated for data of the potential data class, which is less sensitive to delay than data of other data classes. The potential data bearer is also less costly to use compared to other data bearer(s). The fetched segments of content data are stored by the device proxy in an intermediate buffer, and the segments of content data are delivered from the intermediate buffer when requested by the media player.

The invention relates to methods, a wireless communication device and a network node for enabling establishment of at least one Packet Data Network (PDN) connection between a wireless communication device and a communication network. In a first aspect of the invention, a method performed by a wireless communication device of enabling establishment of at least one Packet Data Network (PDN) connection&#x2014;with a communication network is provided. The method comprises submitting, to a node of the communication network, a request to establish the PDN connection, the request being configured to comprise an indication that the request pertains to establishing a PDN connection for transporting Information Centric Networking (ICN) data.

Distinguishing ICN from non-ICN traffic in a mobile network

A method of operating a UPF in a wireless communication system includes receiving a data packet, identifying a PFCP session context associated with the data packet, determining whether a PDR associated with the PFCP session context should be modified or a new PDR should be created, transmitting a request to a session management function to provision a new or modified PDR at the UPF, receiving a session modification response from the SMF provisioning the new or modified PDR for the PFCP session context at the UPF, and applying the new or modified PDR on the data packet.

User plane function control of control plane-user plane separation

An access node () of a cellular network receives an information centric networking request of a user equipment () for a data object. The access node forwards the information centric networking request to a local gateway () associated with the access node (). The local gateway () maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (). In response to the user equipment () moving from a coverage area of the access node () to a coverage area of a further access node (), the access node () and the further access node () perform a handover procedure. The further access node () is associated with a further local gateway () 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 (). The handover procedure initiates alignment of the pending interest table and the further pending interest table with respect to at least one entry associated with the user equipment ().

Handover initiated alignment of pending interest tables

A User Equipment (UE) a method performed at the UE of acquiring content, a Radio Base Station (RBS), and a method performed at the RBS of supplying Information Centric Networking (ICN) content to at least one UE. In a first aspect, a method is performed at a UE of acquiring content. The method comprises submitting a request for content to an RBS, receiving, in reply to the request, the requested content from the RBS, the content being acquired by the RBS from an ICN node and provided to the UE from the RBS upon the RBS receiving the ICN content, storing the received ICN content in a local storage at the UE, and acquiring, when a piece of content is to be rendered at the UE, the piece of content from the received ICN content in the local storage.

Information centric popular content broadcasting

A method is implemented by a transparent proxy to support graceful switchover in a network, where the transparent proxy proxies one or more Transmission Control Protocol (TCP) connections involving a destination Internet Protocol (IP) address. The method includes starting a switchover timer for the destination IP address in response to receiving an instruction from an Application Flow Controller (AFC) to start the switchover timer for the destination IP address and transmitting an indication to the AFC that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired in response to a determination that all of the one or more TCP connections involving the destination IP address that are proxied by the transparent proxy have ended or the switchover timer for the destination IP address has expired.

Service aware switch-over of TCP-flows

A method for enabling establishment of at least one Packet Data Network (PDN) connection between a wireless communication device and a communication network, and a wireless communication device performing the method of enabling establishment of at least one PDN connection with a communication network. The method comprises detecting whether connectivity to an Information Centric Networking (ICN) network is available via the at least one PDN connection for transporting ICN data.
