Dual connectivity flow control

A base station, comprising:

• one or more processors;
• transmission interfaces associated with a first connection to a user equipment (UE), a second connection to a second base station, and a third connection to a core network of a telecommunication network;
• memory storing computer-executable instructions for a flow controller that, when executed by the one or more processors, cause the flow controller to:
• receive a set of data packets for the UE from the core network via a split bearer over the third connection, wherein the split bearer divides into a first leg that passes over the first connection to the UE and a second leg that passes over the second connection to the second base station and from the second base station to the UE;
• determine packet latency goals associated with data packets of the set of data packets;
• determine a first connection latency associated with the first connection and a second connection latency associated with the second connection;
• determine that one of the first leg and the second leg is a lower-latency leg and a second one of the first leg and the second leg is a higher-latency leg based on a comparison of the first connection latency and the second connection latency;
• group the set of data packets into a first subset associated with lower packet latency goals and a second subset associated with higher packet latency goals;
• and
• route the first subset to the UE via the lower-latency leg and the second subset to the UE via the higher-latency leg.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors of a base station of a telecommunication network, cause the base station to perform operations comprising:

• receive a set of data packets for a user equipment (UE) from a core network via a split bearer, wherein the split bearer divides into a first leg that passes over a first connection from the base station to the UE and a second leg that passes over a second connection from the base station to a second base station and from the second base station to the UE;
• determine packet latency goals associated with data packets of the set of data packets;
• determine a first connection latency associated with the first connection and a second connection latency associated with the second connection;
• determine that one of the first leg and the second leg is a lower-latency leg and a second one of the first leg and the second leg is a higher-latency leg based on a comparison of the first connection latency and the second connection latency;
• group the set of data packets into a first subset associated with lower packet latency goals and a second subset associated with higher packet latency goals;
• and
• route the first subset to the UE via the lower-latency leg and the second subset to the UE via the higher-latency leg.
