Systems and methods for supporting multiple uncrewed aerial vehicle (UAV) Service Suppliers (multi-USS) are described. The methods may be performed by a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client located in the UAV with the method performed with the UAV in-flight. Steps may include: sending a registration request to a UAE server, the registration request including an indication of multi-USS capability: receiving a registration response message that includes an indication that the UAE server supports multi-USS capability: receiving a multi-USS configuration request that includes multi-USS configuration parameters related to conditions under which the UAE client may initiate a USS change and a list of allowed USSs: sending a multi-USS configuration response; and performing a multi-USS change and sending a multi-USS change notification based on the multi-USS configuration parameters.

Seamless communication between mobile communication networks complying with different standards is enabled. A method including a first step group executed by a processor of an information processing apparatus, the first step group including the steps of: acquiring a position registration request from a user terminal; judging whether an identification number of a first communication carrier included in the position registration request is different from an identification number of a communication carrier associated with the user terminal, which is registered with a subscriber database; and instructing a mobility management node to set a first network of the first communication carrier when the identification number of the first communication carrier is different from the identification number of the communication carrier registered with the subscriber database.

A relay gateway device includes a processor and a storage, in which when a packet transmission is performed between a first mobile device and a second mobile device and the second mobile device switches from the relay gateway device to another, the IP address of the second mobile device changes from a former IP address to a current IP address. When the first mobile device transmits a first packet to the second mobile device in which the destination address of the first packet is the former IP address, the processor of the relay gateway device modifies the destination address of the first packet into the current IP address according to the former IP address and the current IP address of the second mobile device in a list of the storage and then transmits the first packet to the second mobile device, thereby achieving a seamless transmission during handover.

A method and apparatus for controlling inter-PLMN handover based on CSG lists of equivalent PLMNs is provided. A method for receiving subscriber information of a terminal at a Mobility Management Entity (MME) includes transmitting an update location request message for the terminal to a Home Subscriber Server (HSS), and receiving an update location acknowledgement message with the subscriber information of the terminal from the HSS, wherein the update location request message comprises a list of equivalent Public Land Mobile Networks (PLMNs) among which the MME supports inter-PLMN handover of the terminal. The method and apparatus for controlling inter-plan handover to a CSG cell according to the present invention is characterized in that a control apparatus of a core network acquires the allowed CSG lists for determining a User Equipments (UEs) capability of access to a CSG cell and determines whether to permit inter-PLMN handover based on the allowed CSG lists.

The present invention relates to a wireless communication system, and more specifically, a method and a device for selecting an access network are disclosed. A method by which a terminal selects an access network in a wireless communication system, according to one embodiment of the present invention, can comprise the steps of: determining whether a packet service can be performed through a wireless LAN (WLAN) in use when the packet service is set to select a WLAN access network as an access network of the terminal for the packet service according to a predetermined rule while the terminal is using the WLAN; and performing an access network selection operation including a WLAN selection or a WLAN reselection as a candidate on the basis of the result of the determination step.

An apparatus for the handover of a transmission of a data application. The apparatus includes a computer device, and the computer device includes a wireless receiver and a wireless transmitter. The data application is transmitted over a first wireless network. The computer device includes a handover (SH) proxy. The VoIP handover proxy is to maintain the transmission of the data application while the transmission and state of the data application switches from being transmitted over the first wireless network to being transmitted over a second wireless network. During the switch between wireless networks, the data application is unaware of the switch, and seamless mobility is achieved by using the VoIP handover proxy.

Examples are disclosed for sending or receiving channel state information (CSI) reports associated with coordinated multi-point (CoMP) schemes. The examples include user equipment (UE) constraining CSI feedback to one or more transmission points implementing a CoMP scheme with the UE. The examples also include a transmission point such as an evolved node B (eNB) triggering CSI feedback and receiving a CSI report in response to the trigger. The CSI report generated based on the UE constraining CSI feedback. Constraining CSI feedback may include the UE generating fewer CSI reports, reusing information between CSI reports or increasing an amount of time allowed for processing and generating CSI reports. Other examples are described and claimed.

In a wireless environment, a dockee informs a docking station of the dockee's access point connection credentials and parameters in order for the docking station to become an intermediate proxy for the connection between the dockee and the access point. The docking station takes over the connection between the dockee and the access point.

A link handover method, a network entity, and a terminal are provided. The method includes: sending a first link handover instruction to a second network entity, and maintaining a first data transmission link with a terminal; receiving a link handover response fed back by the second network entity according to the first link handover instruction; sending a second link handover instruction to the terminal according to the link handover response; wherein the second link handover instruction carries radio resource control (RRC) reconfiguration information for establishing a second data transmission link between the terminal and the second network entity.

In a method and an apparatus for optimizing network function (NF) data path discovery for 5G Core network operation, each NF registers itself with the NRF and periodically updates the NRF about the NF's present load, thereby giving the NRF complete information regarding the network topology, the NFs' present load, and the relative capacities of the NFs, which information items can be used in determining the complete optimal path from the RAN to the PSA. When an SMF wants to insert an Intermediate UPF (I-UPF) into a data path, instead of querying the NRF for a UPF serving the present geographical area (e.g., of the User Equipment (UE)) and deciding on the UPF insertion locally based on the present geographical area, the SMF queries the NRF for the complete optimal path. The I-UPF load can be taken into consideration in calculating the optimal path between the RAN and the PSA.
