Abstract: A mobile edge computing (MEC) architecture can facilitate utilization of virtual multi-point non-internet protocol (IP) connections in radio access networks (RAN). Thus, the same mobile device can be addressed with multiple radio access technologies (RATs). The MEC can provide service continuity in multi-access technologies using virtual session, and the MEC can terminate a main session between a core network and the MEC, for the mobile device, via a single IP address, Based on the services and the states of the access network in the multi-access environment, the MEC can dynamically select the RAT and access point as the target to deliver the service over the RAN.

Abstract: Facilitating dynamic satellite and mobility convergence for mobility backhaul in advanced networks (e.g., 4G, 5G, 6G and beyond) is provided herein. Operations of a system can comprise determining that a group of user equipment devices are located in a defined geographic area and are consuming more than a defined level of resources of a wireless communications network based on an amount of network traffic received from the group of user equipment devices. The operations also can comprise configuring an integrated network comprising a first group of terrestrial network devices and a second group of satellite network devices. Further, the operations can comprise routing at least a portion of network traffic associated with the group of user equipment devices among the first group of terrestrial network devices and the second group of satellite network devices.

Abstract: Communications services are provided to a device. For instance, where a communications resource is being used by a device via a first communications service provider (CSP) component associated with a first CSP, based on a probabilistic analysis of loading parameters received from a device at the first CSP component. A likelihood that the device will move can be predicted, comprising determining the likelihood is not less than a threshold likelihood. If likely to move, and based on the loading parameters, a loading profile associated with a user of the device is updated resulting in updated likelihoods of usages of the communication resource by the device via respective other CSP components other than the first CSP component. Further, based on the updated likelihoods of usages of the communication resource, at least part of the communications resource can be allocated to the respective other CSP components to facilitate communications with the device.

Abstract: A framework of abstraction of new and existing 5G radios can enhance capabilities of new and existing micro radios and other short range radio technologies to enable intelligent service delivery, dynamic access learning capability, and network slicing over 5G access networks. Enhancing layer communication for both control and user plane can be tunneled through the hosting layer and exploit a common transport provided by the hosting layer. The tunneling through the hosting layer can also enable the enhance capabilities to access the same radio management functions and can be orchestrated by the same core function. Additionally, provisioning processes can be reduced based on the types of Internet-of-things devices being previously connected to a software-defined networking device.

Abstract: A microservices coordinator function can be utilized to apply dynamic policy changes for microservices. For example, based on outlined service provider policies, user equipment state data, and/or network state data, the microservices coordinator function can determine which microservices to use and what order to use the microservices to increase a performance of the network. The microservices coordinator can perform conflict resolution based on how network traffic should be treated in certain scenarios.

Abstract: Aspects include selecting a first edge device to provide a first part of a service to a user equipment, establishing a first session between the first edge device and a device for a duration of the service, establishing a second session between the first edge device and the user equipment in accordance with a first access technology to transfer first data associated with the first part of the service to the user equipment, and responsive to determining that at least one parameter associated with the second session falls below a threshold performing: handing-over the second session to a second edge device to transfer second data associated with a second part of the service to the user equipment, establishing a third session between a third edge device and the user equipment to transfer third data associated with the second part of the service to the user equipment, or a combination thereof.

Abstract: Facilitating enablement of intelligent service aware access utilizing multiaccess edge computing advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise determining a network service being utilized by a first user equipment device has not been instantiated at a distributed network device and based on the first user equipment device approaching a service range of the distributed network device. The method also can comprise deploying the network service, as a microservice, at the distributed network device prior to the first user equipment device entering the service range of the distributed network device. Further, the method can comprise removing the network service from being deployed at the distributed network device based on a determination that the first user equipment device is no longer within the service range of the distributed network device and a second user equipment device is not utilizing the network service.

Abstract: A software defined network controller receives from a radio access network access point an attach request generated by a user equipment that includes a user equipment identification and an IP address for the radio access network access point. The controller assigns a temporary identification to the user equipment and sends a modified attach request including the temporary identification, and application server identification and an application server IP address to the radio access network access point. The controller configures a forwarding table associated with the radio access network access point so that the access point forwarding table matches the user equipment identification, the application server identification and the application server IP address. The controller configures a service edge creation environment function forwarding table so that the forwarding table matches the user equipment identification mapped to the radio access network access point IP address and instructs an action so that packet traffic to and from the user equipment is processed without an explicit connection oriented signaling protocol.
