A method performed by a wireless device for cell reselection includes identifying a non-terrestrial network (NTN) providing coverage for the wireless device. The wireless device receives a parameter from a network node. The parameter includes an indication to search for a terrestrial network (TN) though the NTN provides coverage for the wireless device. Based on the parameter, the wireless device searches for the TN and prioritizes the TN over the NTN when selecting the TN for cell reselection.

Disclosed are a device and a method for transmitting and receiving data in non-terrestrial and terrestrial network systems. According to an embodiment of the present invention, a wireless transmission and reception method performed by a user equipment in an environment where network nodes providing different cell coverages is implemented including the steps of: receiving information indicating a threshold value based on a synchronization signal block (SSB) or a reference signal received power (RSRP) from a first network node which provides a first cell coverage, measuring a channel between the first network node and the user equipment, comparing the channel measurement value with the threshold value; and on the basis of a result of comparing the channel measurement value with the threshold value, determining whether to initiate connection to a second network node which provides a second cell coverage which at least overlaps the first cell coverage.

Switching between a defined generation of stand-alone (SA) and non-stand-alone (NSA) wireless deployment is presented herein. A system determines user equipment (UE) communication capabilities of a UE that has been determined to be camped on an SA radio access network (RAN) equipment associated with a defined generation of deployment of network equipment, SA network equipment communication capabilities of the SA RAN equipment, and NSA network equipment communication capabilities of an NSA RAN equipment that is associated with the defined generation of deployment of network equipment and that has a defined NSA aggregated channel bandwidth that is greater than a defined SA aggregated channel bandwidth of the SA RAN equipment; and based on the communication capabilities of the UE, the SA RAN equipment, and the NSA RAN equipment, the system determines whether to initiate a handover of a communication session from the SA RAN equipment to the NSA RAN equipment.

A method of quality of experience (QoE) measurement and reporting in a multi-radio access technology (RAT) handover includes receiving, by a user equipment (UE) from a first base station (BS) of a first RAT, first QoE configuration parameters, performing, by the UE, first QoE measurements and second QoE measurements, based on the first QoE configuration parameters, transmitting, to the first BS, one or more first QoE reports based on the first QoE measurements and based on a first format, receiving a handover command, from the first BS, indicating handover from the first BS to a second BS of a second RAT and transmitting, to the second BS, one or more second QoE reports based on the second QoE measurements and based on a second format.

A driving assist system includes a plurality of base stations and a processor. The base stations are configured to be connected to an automated driving vehicle. The processor is configured to transmit, to the automated driving vehicle and based on a quality of communication between a first base station and the automated driving vehicle and a quality of communication between a second base station and the automated driving vehicle, a switching request of switching from the first base station to the second base station. The first base station is one of the base stations to which the automated driving vehicle is connected. The second base station is another one of the base stations and adjacent to the first base station, and is a candidate of the switching from the first base station.

A cell handover method and apparatus, and user equipment are provided. The method includes: when User Equipment (UE) camps on a first cell, obtaining first information, where the first information is used to indicate an abnormal situation when the UE uses a data network corresponding to the first cell; and when the first information meets a first preset condition, handing over from the first cell to a second cell, where the second cell is a cell whose signal quality parameter meets a second preset condition, or the second cell is a cell with the highest access priority; where the first information includes at least one of the following: information about a target data packet, network-related information corresponding to at least one application, a target uplink resource, a data accumulation amount at a data link layer, and a channel quality parameter of the first cell.

This application relates to a cell selection method and apparatus. In an example method, a terminal device performs measurement based on measurement configuration information of N cells and determines M candidate cells based on a measurement result. N is an integer greater than 0, and M is an integer greater than 0 and less than N. The example method further includes the terminal device selecting a target cell from the M candidate cells based on first information. The first information includes coverage information of at least one candidate cell in the M candidate cells.

In one embodiment, a method is disclosed, comprising: providing a first node, a second node and a third node; allocating a set of locally generated Tunnel Endpoint Identifiers (TEIDs) for UEs anchored on the second node; detecting, by a first node, a second node having a connectivity issue; and migrating a User Equipment (UE) connected to the second node to a third node which is accessible; using the set of locally generated TEIDs to identify the UE migration.

Systems and methods are disclosed for a decentralized electronic subscriber identity module (dSIM) and an intelligent multi-chain offloading platform to leverage a plurality of decentralized blockchain-based cellular networks. In one embodiment, an AI-enabled offloading gateway can interconnect a plurality of mobile network operators with said decentralized blockchain-based cellular networks using a dSIM profile. The dSIM profile may contain symmetric and/or asymmetric network access applications, Proof-of-Coverage, and Quality-of-Service applications.

The method comprises determining a corresponding service category for each of a first stack and a second stack based on at least one stack parameter indicated by the first stack and the second stack. The method comprises determining a mode associated with the DSDA UE based on the corresponding service categories of the first and second stacks. The method comprises receiving corresponding band information associated with the first and second stacks from at least one network entity associated with a network.
