A method, apparatus and computer program product are provided to facilitate interworking a plurality of cellular radio access networks and wireless local area networks (WLANs). In the context of a method, a set of information is maintained for a plurality of different cellular radio access networks that defines a relative priority of selection among the cellular radio access networks. The method also includes maintaining wireless access selection information defining a relative priority of selection among one or more WLANs relative to the cellular radio access networks. The method also permits the relative priority of the WLANs to be modified without modification of the set of information. For example, the relative priority the WLANs may be modified in a manner specific to the user equipment or specific to a cell. The method may also include causing notification to be provided to user equipment of the set of information and the wireless access selection information.

A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a first cellular station and a second cellular station. The controller continues to send or receive UP data to or from the first cellular station via the wireless transceiver after receiving a handover command message for a handover of the UE from the first cellular station to the second cellular station, and receives a Radio Resource Control (RRC) request message from the second cellular station via the wireless transceiver after sending a handover complete message to the second cellular station. Also, the controller detaches from the first cellular station in response to receiving the RRC request message.

A gateway station switching method and apparatus. When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station.

An apparatus includes a includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives signaling that indicates edge application service relocation for transferring a user equipment (UE) session for a UE to a target edge data network. The processor identifies an edge application service in the source edge data network processing media content corresponding to the UE session; generates a resource template for the edge application service including requirements for running the edge application service; transmits a request for the edge application service relocation to the target edge data network, the request including the resource template; and enables the edge application service relocation for the user equipment from the edge application service at the source edge data network to an edge application service at the target edge data network.

A method for advertising a route, applied to a layer 3 network in an open systems interconnection OSI model. The network includes a control plane network element and a user plane network element that are connected to each other, and the method includes: receiving, by the user plane network element, a packet whose source IP address is a first IP address; determining, by the user plane network element, that the first IP address is not authenticated; sending, by the user plane network element, an authentication request that includes the first IP address to the control plane network element; receiving, by the user plane network element, a first session from the control plane network element; and advertising, by the user plane network element, first routing information based on the first session, where a destination address of the first routing information is the first IP address.

An operation method of a first communication node may comprise: establishing a first wireless connection with a GCS; establishing a second wireless connection with the GCS; transmitting and receiving data to and from the GCS through a first end-to-end connection based on the first wireless connection; reporting a communication quality of the first wireless connection to the GCS; receiving a link switch request from the GCS; switching a link from the first wireless connection to the second wireless connection based on the link switch request; and transmitting and receiving data through a second end-to-end connection based on the second wireless connection.

Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.
