The present disclosure proposes a proxy method, comprising receiving a request for a service in a first architecture from a requester network function (NF) in a second architecture, obtaining a response of the service from a serving NF on behalf of the requester NF, and sending a further response to the requester NF based on the response of the service. The proxy method may be implemented on a NF or a function entity within a NF.

Method and device for proxy between different architectures

The embodiments herein relate to dynamic backup AMF determination and publication. In one embodiment, there proposes a method () in a Access and (Start Mobility Management Function (AMF) node (), comprising: obtaining (S) first information of the AMF node (), the first information at least includes one or more identifier; obtaining (S) second information of each of all other nodes () within the same AMF set as the AMF node (), the second information includes Relative Capacity (RC) and one or more identifier; and determining (S) backup AMF for at least one identifier of the AMF () based on the first information and the second information in an autonomous way, without the participation of the Operation Administration and Maintenance (OAM) (). With embodiments herein, the backup AMF information is determined per GUAMI granularity and published automatically among all AMFs within the AMF set in an autonomous way.

Dynamic backup AMF determination and publication

The present disclosure provides a method in a Next Generation Core Control Function (NG-CCF) node for communication with a Next Generation Policy Control Function (NG-PCF) node. The method comprises: communicating network related parameters with the NG-PCF node via a direct interface between the NG-CCF node and the NG-PCF node.

Method and node for communication between next generation core control function and next generation policy control function

The embodiments herein relate to a method performed by a local subscriber node for handling attachment of a User Equipment (UE) to a central network. The local subscriber node comprises default subscription data which is common for all UEs which are associated with a local network. When a connection to a central subscriber node is accessible, the local subscriber node obtains authentication data associated with the default subscription data from the central subscriber node. When the UE requests attachment to the central network when the connection to the central subscriber node is inaccessible, the local subscriber node sends the obtained authentication data for the UE to a mobility management node.

Method and node for handling attachment of a UE

Some example embodiments presented herein may be directed towards a core network node, and corresponding method, for determining a modification and/or utilization of radio resources. The core network node may be in a Radio Network. Some example embodiments may comprise receiving, in the core network node, a notification for a radio resource modification and/or utilization for a User Equipment (UE) based on at least one handover criterion. Some example embodiments may further comprise establishing and/or modifying the radio resource based on the at least one handover criterion.
