An example method is provided in one example embodiment and includes establishing a mobility context associated with a user equipment that includes a designation of a first radio access network as a primary access network and a second radio access network as a secondary access network. The method further includes defining an initial value for a data count variable representative of a number of consecutive uplink packets associated with the user equipment received over the first radio access network. The method further includes receiving at least one first uplink packet associated with the user equipment from at least one of the first radio access network and the second radio access network, modifying a value of the data count variable when the first uplink packet is received over the second radio access network, setting the value of the data count variable to the initial value of the data count variable when the first uplink packet is received over the first radio access network, and modifying the mobility context if the value of the data count variable is equal to a predetermined value.
