Abstract
Abstract A server device may identify that a user device is connected to a first radio access network (“RAN”), via a first technology. The server device may identify that the user device is capable of accessing a second RAN, via a second technology, where the second RAN is different from the first RAN, and where the second technology is different from the first technology. The server device may also receive an indication that the first RAN is congested. The server device may further determine, based on the indication that first RAN is congested, and further based on identifying that the user device is capable of accessing the second RAN via the second technology, that the user device should be handed over to the second RAN. Additionally, the server device may instruct the user device to connect to the second RAN via the second technology.
