Embodiment Construction

[0016] For the sake of clarity and simplicity, this specification refers to structural and / or functional units, related communication standards, protocols and / or services, and other components generally known in the art, without further detailed description of their configuration or operation, unless They are modified or changed according to and / or to suit the preferred embodiments presented herein.

[0017] This specification relates to providing access to selected IP multimedia applications and / or services via IMS to roaming wireless or mobile devices using a dual IP anchoring approach. More specifically, this specification describes a system and / or method for supporting QoS and / or access admission control and / or management not only for visited network traffic, but also for home network traffic. The above objects are suitably achieved by implementing additional packet filtering and / or policy enforcement support at the Home Gateway to which one of the IP tunnels is anchored. ...

Abstract

A method of supporting access to a selected Internet Protocol (IP) multimedia application via an IP Multimedia Subsystem (IMS) is provided for a roaming mobile node (MN)—i.e., user equipment (UE)served by a wireless telecommunications system. The method includes: includes establishing a first IP tunnel between the UE and a local access gateway of a visited network, the first tunnel being anchored at the local access gateway; establishing a second IP tunnel between the UE and a home gateway of a home network, the second tunnel being anchored at the home gateway; receiving data packets at the local access gateway for the UE; filtering the packets received at the local access gateway to suitably classify corresponding traffic into one of a plurality of data flows supported within the first tunnel at varying Quality of Service (QoS) levels; and filtering the received packets.

Description

technical field [0001] The subject of the invention relates to the field of wireless telecommunication networks. Certain applications are implemented in conjunction with the Internet Protocol (IP) Multimedia Subsystem, and the specification makes specific references thereto. It is to be understood, however, that aspects of the inventive subject matter are also applicable to other similar networks, devices and / or applications. Background technique [0002] Known in the field of wireless telecommunications, the IP Multimedia Subsystem (IMS) is an architecture (originally designed by the wireless standards body 3rd Generation Partnership Project (3GPP)) for delivering IP multimedia to wireless mobile device users. That is, IMS supports the use of IP multimedia applications and / or services in wireless telecommunication systems or networks. In general, IMS enables wireless network service providers and / or operators to offer their subscribers (ie mobile users) based and / or built...
