Reducing packet loss in a mobile data network with data breakout at the edge

A method for a data offload gateway in a breakout system associated with one of a plurality of basestations to utilize a radio link control (RLC) reset command for synchronization during breakout in a mobile data network, the method comprising the steps of:

• performing the steps of:
• 1) breaking out a data session to a user equipment (UE);
• 2) monitoring network traffic to and from the breakout system;
• 3) determining if sequence numbers between a first RLC entity and a second RLC entity are out of synchronization;
• and
• 4) where the sequence numbers are out of synchronization, performing an RLC reset towards the UE and towards a radio network controller (RNC) in a core network to bring the first RLC entity and the second RLC entity back into synchronization.

A method for a breakout system to utilize a radio link control (RLC) reset command synchronization during breakout in a mobile data network with a breakout system, the method comprising the steps of:

• (A) a plurality of antennas sending and receiving network messages between user equipment and a plurality of basestations in the radio access network, each basestation communicating with a corresponding one of the plurality of antennas;
• (B) a data offload gateway in the breakout system associated with one of the plurality of basestations performing the steps of:
• 1) breaking out a data session to a user equipment (UE);
• 2) monitoring network traffic to and from the breakout system;
• 3) determining if sequence numbers between a first RLC entity and a second RLC entity are out of synchronization;
• 4) where the sequence numbers are out of synchronization, performing an RLC reset towards the UE and towards a radio network controller (RNC) in a core network to bring the first RLC entity and the second RLC entity back into synchronization;
• wherein the network traffic monitored by the data offload gateway is a first sequence number in a service data unit (SDU) queue in an RLC data structure maintained by the first RLC entity and a second sequence number in a SDU queue in an RLC data structure maintained by the second RLC entity;
• and
• wherein the data offload gateway monitors network traffic to determine if data communication is moved from a low frequency channel to a high frequency channel that causes the first RLC entity and the second RLC entity to become out of synchronization.
