Abstract: Traffic associated with user equipment that are coupled to a first radio access network is steered to a second radio access network based on an adaptable signal strength criterion. The signal strength criterion is related to real-time network load conditions of the first radio access network and can be broadcasted from a serving access point to the user equipment. Moreover, the signal strength criterion facilitates steering, to the second radio network, traffic associated with user equipment that are located closer to a cell edge of the first radio access network before steering traffic associated with user equipment are located further away from the cell edge. In addition, based on the network congestion within the first radio access network, the signal strength criterion is modified to adjust the number of user equipment that are steered to the second radio network.

Abstract: Facilitating network slicing information preservation in advanced networks in advanced networks is provided herein. Operations of a system include receiving, from second network equipment, network slice configuration information for a user device during a first handover of the user device from the second network equipment to the first network equipment. The network slice configuration information can include information indicative of a first network slice and a second network slice generated via a microservice of a network intelligent controller. Further the operations can include transmitting, to third network equipment, the network slice configuration information for the user device during a second handover of the user device from the first network equipment to the third network equipment.

Abstract: Facilitating conditional fast return to stand alone advanced networks after voice fall back is provided herein. Operations of a system can include controlling a first communication for a user equipment based on a connection request that comprises an indication of a fall back procedure. The connection request is associated with the user equipment via which the first communication is scheduled to occur. The operations can also include, based on a determination that the first communication has completed at the user equipment, releasing a first control of the user equipment. Further, the operations can include delaying a redirection of the user equipment to the network equipment for a second control of a second communication scheduled to occur at the user equipment. Delaying of the redirection can be based on a condition defined for a service executing on the user equipment determined not to be supportable by the network equipment.

Abstract: 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.
