A method performed by a first network node associated with a public network in a first cell includes determining that a first wireless device operating on a first frequency band in the first cell is proximate to a second cell associated with a non-public network operating on a second frequency band. The first network node offloads the first wireless device to a third frequency band.

A signal measurement method and apparatus, and a communication device and a storage medium are provided. The method includes that a first communication device receives, via a first type of network, a measurement result, sent by a second communication device, for a second type of network.

The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transfer rate beyond a 4th generation (4G) communication system, such as long-term evolution (LTE). According to various embodiments of the present disclosure, a security method of a mobility management apparatus of a second system in a wireless environment may comprise the steps of: receiving a handover request for a terminal connected to a first system; transmitting the handover request to a base station of the second system; and receiving a handover ACK including security information generated by the base station of the second system and transmitting the same to the first system.

A communication device for handling mobility from a long-term evolution (LTE) network to a fifth generation (5G) network comprises a storage device storing instructions of transmitting a first LTE Non-Access Stratum (NAS) message to the LTE network; receiving a second LTE NAS message in response to the first LTE NAS message, from the LTE network; and transmitting a message to the 5G network, after determining to communicate with the 5G network instead of the LTE network, wherein the message comprises a slice information, and the slice information is comprised in the first LTE NAS message or in the second LTE NAS message.

A method and system for controlling uplink-path switching of a user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and where one of the first and second air-interface connections defines a primary uplink path of the UE. An example method includes (i) predicting that a handover trigger for handover of the UE from the first access node to a third access node will occur and (ii) responsive to at least the prediction that the handover trigger will occur, but before the handover trigger occurs, forgoing application of at least a portion of an uplink-path-switch control process for dynamically controlling which of the UE's connections will be set as the UE's primary uplink path.

As described herein, one of a third generation (3G) radio access network (RAN) or a fifth generation (5G) RAN may be selected to receive a handover of a communication session from a fourth generation (4G) RAN. The 3G RAN or 5G RAN may be selected based on at least one of performance measurements for the 3G RAN and the 5G RAN, a preference for the 3G RAN or the 5G RAN, or a performance threshold for the 3G RAN or for the 5G RAN. The handover to the selected one of the 3G RAN or 5G RAN may then be initiated.
