Systems and methods for splitting and recombining communications in multi-network environments
First Claim
1. A network device comprising:
- a memory; and
a processor, coupled to the memory, configured to;
provide a first network communication module and a second network communication module, wherein the first network communication module utilizes a first radio access technology and the second network communication module utilizes a second radio access technology; and
split a user data communication stream into a first portion and a second portion, the first portion to be transmitted across a first radio access technology pathway of a first network using the first network communication module and the second portion to be transmitted across a second radio access technology pathway of a second network using the second network communication module,wherein the first portion and the second portion are determined based on a power saving mode offered by the first network, the power saving mode resulting in power savings of the first radio access technology relative to the second radio access technology, andwherein the first and second radio access technologies are different.

Abstract
Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.

9. A method for splitting an outbound communication stream in a wireless device supporting a first radio access technology and a second radio access technology, comprising:
-
detecting a first network of the first radio access technology and a second network of the second radio access technology; splitting a user data communication stream into a first substream and a second substream, the first substream to be transmitted over the first network and the second substream to be transmitted over the second network, wherein the first substream and the second substream are determined based on a power saving mode offered by the first network, the power saving mode resulting in power savings of the first radio access technology relative to the second radio access technology; and transmitting the first substream over the first network and the second substream over the second network, and wherein the first and second radio access technologies are different. - View Dependent Claims (10, 11, 12, 13, 14)
