Claim of US Patent No. 10,893,561

1. A base station comprising:one or more processors; and
a computer-readable storage medium storing a plurality of computer-executable components that are executable by the one or more processors to perform a plurality of actions, the plurality of actions comprising:
providing a first wireless connectivity of a first regulated wireless communication standard to a user equipment (UE) of a cellular network via a master node of the base station, wherein user plane data is forwarded to the UE through the master node according to a first user plane path;
determining whether the master node and a secondary node are collocated at a same cellular tower of the base station;
requesting a secondary node to provide a second wireless connectivity of a second regulated wireless communication standard to the UE, wherein:
if the master node and the secondary node are not collocated at a same cellular tower of the base station, the user plane data is forwarded to the UE through the secondary node according to a second user plane path that is established with the cellular network; and
if the master node and the secondary node are collocated at a same cellular tower of the base station, the user plane data is forwarded to the UE through the secondary node according to the first user plane path.
