Systems, apparatuses, and methods are described for wireless communications. A base station may receive resource status information. The base station may use the resource status information for serving one or more network slices for a wireless device.

A first base station receives from a core network entity, a first message indicating a request for a session resource for a wireless device. The session resource is associated with a first network slice. The first base station sends to a second base station, a second message indicating a handover request for the wireless device towards a first cell of the second base station. The first message comprises: a packet flow identifier of a packet flow associated with the first network slice; a network slice identifier of the first network slice; and a cause information element indicating that the handover request is to provide at least one network slice for the wireless device. The at least one network slice comprises the first network slice. The first base station receives from the second base station, a third message indicates an acceptance or a rejection based on the second message.

Continuous communication during network handovers may ensure the sending and receiving of mission-critical data by applications is performed without interruption using multiple communication networks. A request from an application to establish a communication session with an IP Multimedia Subsystem (IMS) core of a wireless carrier network for routing communication traffic to the IMS core may be received. Subsequently, an access point name (APN) designated by an APN parameter of the application may be determined. Accordingly, in response to a determination that the APN parameter designates a continuous link APN, the communication traffic may be routed via a communication session that seamlessly switches between a continuous link APN bearer on a radio access network of the wireless carrier network and a continuous link APN tunnel on a remote network that connects to an Evolved Packet Data Gateway (ePDG) of the wireless carrier network.

The present invention relates to the field of communications technologies and discloses service transmission methods, apparatus, and devices. In one embodiment, a method includes: obtaining, by a target server or user equipment, an Internet Protocol (IP) address assigned by a target gateway to the user equipment; establishing a Multipath Transmission Control Protocol (MPTCP) connection between the user equipment and the target server based on the IP address assigned by the target gateway to the user equipment, where the MPTCP connection between the user equipment and the target server and an MPTCP connection between the user equipment and a source server are bound to a same MPTCP session; and transmitting a service data packet using the MPTCP connection between the user equipment and the target server. The service data packet is transmitted using the target gateway so a transmission path is optimized and a service transmission delay is reduced.

Disclosed are various embodiments for managing location-based service zones. Specifically, a dynamically sized geographic region surrounding a client device location can be created. Location-based service zones within the geographic region can be selected. If the amount of location-based service zones identified within the geographic region exceed a client-supported limit, a subset of location-based service zones are selected and sent to the client device for monitoring.

A wireless communication system for performing communication and computing includes a plurality of cells configured to perform the communication between at least one user equipment and at least one network; and an Artificial Intelligence (AI) computing platform comprising a plurality of AI slices to perform the computing, wherein the plurality of cells are located in air, space, sea, or land.

Systems and methods to utilize user device network slicing and cell support to manage handover of communications for user device. A request to handover management of a user device from a first cell to a second cell is received. One or more possible cells for the handover are then identified. If the user device is utilizing network slicing, then the second cell is selected from the one or more possible cells based on that cell also supporting network slicing. If the cell supports the same network slice as being utilized by the user device, then the handover of the user device to the second cell is initiated.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is in communication with a first slice of a network via a first control entity at the UE, and may determine that the UE is to further communicate with a second slice of the network. The UE may transmit a control message associated with the first control entity, where the control message may include a request pertaining to communications with the second slice. The UE may receive, in response to the control message and at the first control entity, a reconfiguration message indicating a configuration for using the second slice. The UE may communicate with the second slice of the network based on the configuration.

A network slice handover method and apparatus as applied to the network slice field can include: a slice selection network element receives resource information of an original network slice from a network slice management function network element, where the resource information of the original network slice includes a performance indicator of the original network slice, alarm information of the original network slice, and/or an analysis report for the original network slice; determines, based on the resource information of the original network slice and a network slice handover policy, whether to hand over a terminal device in the original network slice to a target network slice.

There are provided measures for feedback on network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a terminal connected to at least one network slice and being subject to a handover from a source access point to a target access point, receiving a handover command message including handover assistance information indicative of a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, selecting first random access channel resources as attempt random access channel resources from said first pool of random access channel resources, attempting random access to said target access point utilizing said attempt random access channel resources, storing, if said attempting random access to said target access point utilizing said attempt random access channel resources is unsuccessful, attempt related information to an attempt failure list, and transmitting, if said attempting random access to said target access point utilizing said attempt random access channel resources is successful, said attempt failure list to said target access point.
