Internet Engineering Task Force (IETF) D. Kutscher Request for Comments: 7778 F. Mir Category: Informational R. Winter ISSN: 2070-1721 NEC S. Krishnan Ericsson Y. Zhang Hewlett Packard Labs CJ. Bernardos UC3M March 2016 Mobile Communication Congestion Exposure Scenario Abstract This memo describes a mobile communications use case for congestion exposure (ConEx) with a particular focus on those mobile communication networks that are architecturally similar to the 3GPP Evolved Packet System (EPS). This memo provides a brief overview of the architecture of these networks (both access and core networks) and current QoS mechanisms and then discusses how congestion exposure concepts could be applied. Based on this discussion, this memo suggests a set of requirements for ConEx mechanisms that particularly apply to these mobile networks.

Informational [Page 2] RFC 7778 ConEx Mobile Scenario March 2016 1. Introduction Mobile data traffic continues to grow rapidly. The challenge wireless operators face is to support more subscribers with an increasing bandwidth demand. To meet these bandwidth requirements, there is a need for new technologies that assist the operators in efficiently utilizing the available network resources. Two specific areas where such new technologies could be deemed useful are resourceShow full document text
