A network node () of a radio access network (RAN) of a wireless communication network () provides user plane security by establishing a secure tunnel between first and second tunnel endpoints () that will handle respective protocol layers of a same protocol stack for a Data Radio Bearer (DRB) () that is dedicated to user plane traffic and has yet to be established. Establishing the secure tunnel comprises exchanging an inner Internet Protocol (IP) address and an outer IP address of each of the endpoints () between the endpoints ().

User plane security in split RAN architectures

In a process for adding a base station as a secondary base station, and for example in 5 response to a UE Context Setup Request or a UE Context Modification Request, a distributed unit of a base station selects a feature set, and informs a central unit of the base station of the selected feature set.

Baseband processing capability handling in split deployment

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

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.

Changing GTP TEIP upon UE resume

A method in a network node including a gNB-Distributed Unit (DU) logical node and a gNB-Central Unit (CU) logical node for determining admission of a user equipment (UE) includes the steps: the gNB-DU receiving a connection request from a UE; in response to a determination that the gNB-DU is not able to serve the UE, sending an initial uplink radio resource control (UL RRC) message that does not include a configuration for signaling radio bearer 1 (SRB1) from the gNB-DU to the gNB-CU; in response to receiving, at the gNB-CU, the UL RRC message that does not include the configuration for SRB1, responding to the gNB-DU with a radio resource control (RRC) ConnectionReject message; and transmitting the RRC ConnectionReject message from the gNB-DU to the UE to reject the UE.

Information exchange for initial user equipment access

A method performed by a serving network node for handover of a communication device to a target network node is provided. The method includes determining, based on content of an Information Centric Networking, ICN, request, a need for handover, and initiating, in response to the determining, a handover of the communication device to the target network node. A method performed by a network entity is also provided. A network node, network entity, computer programs and computer program products are also provided.

The invention relates to methods and devices of distributing data content in an Information Centric Networking (ICN) network where access of a wireless communication device publishing the data content is transferred from a source access point serving wireless communication device to a target access point. In an aspect of the invention, a method performed by a source access point () is provided for distributing data content in an ICN network () where access of a wireless communication device () publishing the data content is transferred from the source access point () serving the wireless communication device () to a target access point (). The method comprises notifying (S) the target access point () of an ICN routing identifier associated with the wireless communication device () providing the requested data content, notifying (S) the target access point () of any pending ICN requests directed to the wireless communication device () such that that any data content provided by the wireless communication device () to the target access point () is forwarded to the original requester, and updating (S) an ICN Forwarding Information Base, FIB, at the source access point () such that any ICN request directed to the wireless communication device () is forwarded to the target access point ().

Seamless mobility for ICN producers

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

Method and device for facilitating handling content in an information centric network (ICN)

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.
