A method for securing radio connections comprises performing a connection setup with a user equipment (UE); determine that security information is needed for the UE based on an event which triggers a need of the security information; send an indication to a second network node to request the security information for the UE; and receiving the security information from the network node via a UE context setup procedure. The method may avoid a waste of resource in network by determining whether the UE is required to set up a security procedure by either a network node of a radio access network or a management and function node of a core network.

Method, apparatus, and system for securing radio connections

Embodiments include methods performed by a first network node configured to operate in a radio access network (RAN). Such methods include determining a radio access technology (RAT)/Frequency Selection Priority (RFSP) index associated with a user equipment (UE) served by the first network node. Such methods include sending, to a second network node, a request for the second network node to establish dual connectivity with the UE as a secondary node (SN). The request includes the RFSP index. Other embodiments include complementary methods performed by the second network node, as well as network nodes configured to perform such methods.

Slicing of network resources for dual connectivity using NR

A wireless device, a network node, a core node and methods therein, for managing reachability of the wireless device. The wireless device starts an AS (Access Stratum) reachable timer when entering an inactive state. If the AS reachable timer expires while still in the inactive state, the wireless device sends to the network node a reachable notification indicating that the wireless device is reachable. If entering a connected state before the AS reachable timer expires, the wireless device stops the AS reachable timer when changing from the inactive state to a connected state. If the core node receives from the network node a not reachable notification indicating that the wireless device is not reachable, the wireless device can be marked as not reachable via paging.

Methods, wireless device, network node and core node for managing reachability of the wireless device

According to certain embodiments, a method is provided for resource allocation between a first network node () associated with a first radio access technology (RAT) and a second network node () associated with a second RAT where the first RAT and the second RAT use an overlapping spectrum. The method includes determining, by the first network node, one or more resources of a plurality of resources for use by the second network node. The plurality of resources is represented by a bit string. A message is transmitted to the second network node. The message includes the bit string in which the one or more resources for use by the second network node are indicated.
