    Abstract: Provided are a device and method for maintaining a communication session during a network transition. In one example, the method includes monitoring, by a client, a connection with a first network to determine whether a signal strength of the connection falls below a threshold value. The client establishes a connection with a second network if the signal strength of the connection with the first network falls below the threshold value. Establishing the connection with the second network includes obtaining an address and port assignment corresponding to the client from the second network. The client uses the obtained address and port assignment to maintain a communication session during the changeover from the first network to the second network.
