The present disclosure provides a method and a device for switching an Internet access mode of a gateway device. The method includes that: a DNS detection domain name is acquired, the DNS detection domain name being a predefined domain name; at least according to the DNS detection domain name, it is determined whether an EWAN connection is online, the EWAN connection being a network connection of the gateway device in an EWAN mode; and in a case that the EWAN connection is offline, the Internet access mode of the gateway device is switched to an LTE mode.

The disclosed technology is directed towards preventing a handover of a Wi-Fi call to a Fifth Generation (5G) standalone cellular network. In one alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device. In another alternative, a 5G standalone usage setting is disabled on a mobile device when Wi-Fi calling is enabled on the mobile device and the mobile device is connected to a Wi-Fi network, which facilitates camping on a 5G standalone network when the mobile device is not connected to a Wi-Fi network. In yet another alternative, a 5G standalone usage setting is disabled on a mobile device when an evolved packet data gateway (ePDG) tunnel is set up on the mobile device, which similarly facilitates camping on a 5G standalone network when the ePDG tunnel is torn down.

The present invention provides an AP handover method based on double wireless network interface cards. A mobile terminal actively scans the signal strength of an AP, compares the scanned signal strength with the signal strength of a currently accessed AP, and if the signal strength is greater than the signal strength of the current AP, starts handover; otherwise, continuously scans till the handover succeeds. To reduce the handover delay and in accordance with the characteristic that the moving paths are basically fixed in industrial application scenarios, the present invention provides a pre-learning mechanism, that is, before formal application, information such as the location of the AP and the handover sequence in the application scenario is learned and stored in a terminal node, so that specific scanning and handover can be implemented in formal application. The present invention solves the problem of rapid AP handover in the industrial mobile network scenario, the double wireless network interface cards are used to achieve handover without interruption, and the pre-learning mechanism is used in specific industrial application scenarios, so the scanning delay is further reduced.

Embodiments herein relate to a method performed by a first radio network node (12) for enabling a mobility procedure of a wireless device (10) between the first radio network node (12) and a second radio network node (13) in a wireless communication network (1). The first radio network node (12) determines to delegate a handover decision for the wireless device (10) to the second radio network node (13). The first radio network node (12) transmits an indication to the second radio network node (13), which indication indicates a delegation of the handover decision for the wireless device (10) thereby enabling the mobility procedure of the wireless device (10).

A non-transitory computer readable medium comprising instructions which causes performance of operations comprising: receiving, by a second network coordination device, current state information of a client device, including a transmit counter and a receive counter, from a first network coordination device, wherein the first network coordination device is a primary network coordination device for the client device and the second network coordination device is a standby coordination device for the client device; and responsive to detecting a particular event, the second network coordination device (i) transitioning to be the primary network coordination device for the client device, (ii) incrementing the transmit counter by an offset, and (iii) transmitting a message to the client device including the incremented transmit counter is shown.

Aspects of the subject disclosure may include, for example, a method in which a processing system detects user equipment (UE) in communication with a network via a serving cell of the network; the network is configured to facilitate communications by one or more terrestrial UEs and one or more aerial UEs. The system monitors messages from an aerial UE regarding detection of a cell other than the serving cell, and receives information from the aerial UE regarding the detected cell. The method further includes analyzing the information to estimate a first quantity associated with the detected cell location relative to the serving cell and a second quantity associated with a power received at the aerial UE from the detected cell. The method also includes determining, based on the analyzing, whether the aerial UE is an unauthorized aerial UE. Other embodiments are disclosed.

In order to prevent deterioration of QoE of a user in intersystem handover, an apparatus according to the present invention includes: an information obtaining unit configured to obtain network slice related information related to a network slice used by a terminal apparatus in a first radio communication system; and a first communication processing unit configured to transmit, to a second network node of a second radio communication system, a message for intersystem handover of the terminal apparatus from the first radio communication system to the second radio communication system, the message including the network slice related information.

A mobile wireless terminal is provided that controls a timing or a position in which handover is conducted between a plurality of access points, the terminal includes an antenna that receives a radio wave from an access point, a wireless communication interface that measures the radio wave, a processor, and a memory. The processor stores first and second received powers from respective first and second access points in the memory, conducts handover where a difference acquired by subtracting the first received power from the second received power is equal to or greater than a predetermined threshold, estimates a first available bandwidth before the handover and stores it in the memory, estimates a second available bandwidth after the handover and stores it in the memory, and controls a timing when handover of the mobile wireless terminal is conducted based on an available bandwidth difference between the first and second available bandwidths.
