Claim of US Patent No. 9,402,209

1. A computing system comprising:
one or more procesors; and
computer storage memory having computer-executable instructions embodied thereon that, when executed by the one or more processors,
implement a method for encoding a first set of data packets at a gateway of a telecommunications network, the method comprising:

receiving an indication that a handover of a user device is to occur, wherein data associated with the user device is to be
transferred from a source cell to a target cell;

based on the indication that the handover is to occur, encoding the first set of data packets utilizing linear network coding;
sending the encoded first set of data packets to the target cell, wherein the encoded first set of data packets is decoded
by the target cell to provide decoded data packets, and the decoded data packets are sent by the target cell to the user device
in a sequential order; and

based on a completion of the handover, determining not to encode a second set of data packets and sending the second set of
data packets as unencoded data packets to the target cell.
