Embodiment Construction

[0061] The techniques disclosed herein can be used to aggregate the bandwidth of an LTE femtocell with an external WiFi router. These techniques can help overcome shortcomings of conventional LTE femtocell systems. In the example shown here, the WiFi router is integrated with a modem that connects to a broadband Internet connection, such as a DSL modem or cable modem. However, in other implementations, the modem and WiFi router may be separate entities that communicate using a wired or wireless network connection. The techniques described herein can be applied to both uplink and downlink transmissions, and to components of the Evolved Packet Core (EPC) of an LTE network, such as Mobility Management Entity (MME), Serving Gateway (SGW), Home It is transparent to the user server (HSS), packet data network gateway (PGW) and / or other components of the core network architecture. Furthermore, while the example implementations discussed herein are implemented for LTE, the techniques...

Abstract

Techniques for aggregating wireless communications are provided. These techniques include a method for aggregating wireless communications traffic in a femtocell. The method includes receiving at a femtocell a stream of data packets for a mobile device from a wireless router, selecting a transmission mode for sending data packets of the stream of data packets from the femtocell to the mobile device. The first transmission mode includes transmitting the data packets from the stream via a Long Term Evolution (LTE) interface of the femtocell. The second transmission mode includes transmitting the data packets from the stream via a WiFi interface of the wireless router. The third transmission mode includes transmitting a first portion of the data packets to the mobile device via the LTE interface and routing a second portion of the data packets to the wireless router for transmission to the mobile device via the WiFi interface.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and is assigned to the assignee of U.S. Patent Application No. 13 / 920,832, filed June 18, 2013, entitled "LTEANDEXTERNALWIFIBANDWIDTHAGGREGATION," and is hereby expressly incorporated herein by reference . Background technique [0003] A Long Term Evolution (LTE) femtocell may be installed in a home or workplace and used as a wireless base station for a mobile communication network. Typically, at home or at work, a femtocell is connected to a mobile communication network provider's network via a broadband connection. For example, a femtocell may be connected to a Digital Subscriber Line (DSL) router or cable modem via an Ethernet connection or other wired or wireless network connection. [0004] A femtocell may be configured to serve as a primary interface from user equipment (UE) or other mobile devices such as smartphones, tablets, or other types of mobile devices configured to ...
