  • Patent number: 11190980
    Abstract: A cellular system having both 4th-Generation (4G) and 5th-Generation (5G) cellular networks may be configured to use Non-Standalone (NSA) dual connectivity, in which wireless data transmissions may be made using either 4G Long-Term Evolution (LTE) or 5G New Radio (NR) radio access networks. Data packets submitted for wireless transmission are associated with one or more packet tags, such as an application identifier and a customer identifier. A radio protocol stack receives the data packets and associated packet tags and determines for each data packet, based on the associated packet tags, whether to transmit the packet using the LTE radio access network or the NR radio access network. This determination may be based in part on a routing policy that has been created and/or provided by a cellular services provider.
