Definitions

  • the term "established communications with a network” refers to a device or equipment having performed the various steps of a protocol (based on a standard being followed by the network) to allow the network to recognize and validate the device as a part of the network and allow the device to exchange signaling and/or traffic information with the network.
  • Signaling information refers to information used by a network in the context of a procedure or protocol to manage communications and establish communications within its network elements and with devices or equipment that may or may not be part of its network elements.
  • Traffic information refers to information being conveyed (transmitted and/or received) within a network or between a network and a device, system or other network where such information originate from other networks or from user devices who have established communications with the network. Examples of types of traffic information include, but are not limited, voice, video, multimedia, graphics, and text information.
  • the user device uses an MPTCP (Multi-path TCP or Multi- path Transmission Control Protocol) agent to format and route information through the tunnel established within the first network type or via the direct path (i.e., uplink interface) to the common point (interface between first network and common network) in the first network type.
  • MPTCP Multi-path TCP or Multi- path Transmission Control Protocol
  • the common point interface between first network and common network
  • the terms 'proxy' and 'agent' used with respect to the term 'MPTCP' will be used interchangeably.
  • eNodeB 104 routes this information to the S- GW 108 via the SI -UP interface 120 which then routes the information to the P-GW 1 10 via the S5/S8 interface 124; the P-GW 1 10 transfers it to the common point via interface 126.
  • Other signaling information and traffic information having the same instructions will be routed and processed in the same manner as this initial signaling message. It is to be noted that the encapsulating information is stripped off at the tunnel endpoint (i.e., AP 1 16 or alternatively UE/STA 102) upon the information reaching its destination as will now be discussed with respect to FIG. 5.

Abstract

La présente invention concerne un réseau cellulaire LTE et un réseau WiFi dont les zones de couverture se chevauchent et qui permettent à des dispositifs utilisateurs accédant aux deux réseaux d'effectuer une agrégation de canal de liaison descendante à travers une fonction de tunnellisation fournie par le réseau cellulaire, des informations de liaison montante destinées au réseau WiFi étant acheminées à travers un tunnel IP à travers le réseau cellulaire pour atteindre finalement le réseau WiFi par l'intermédiaire d'un point commun ou d'un réseau commun auquel le réseau WiFi et le réseau cellulaire sont connectés. Des dispositifs utilisateurs ayant accès aux deux réseaux peuvent établir le tunnel pendant l'établissement de communications entre ces dispositifs utilisateurs et le réseau WiFi, et utiliser le tunnel sous la forme d'une liaison montante pour transmettre des informations au réseau WiFi, qui est actionné dans un mode de diffusion uniquement ou dans un mode sans accusé de réception.
