Abstract
Systems and methods for session-aware GTPv2 load balancing are described. In some embodiments, a method may include receiving a first and a second transaction between an MME and an S-GW over an S11 interface of an LTE/SAE network using a control portion of a second version of a GTPv2-C protocol and storing an uplink UP TEId and IP address, a downlink CP TEId and IP address, and an uplink CP TEId and IP address obtained from the first transaction, and a downlink UP TEId and IP address obtained from the second transaction. The method may further include identifying messages between an eNodeB and the S-GW over a direct tunnel using a user portion of a GTPv1-U protocol as belonging to a session in response to the messages including at least one of: the first uplink UP TEId and IP address, or the first downlink UP TEId and IP address.
