The Differentiated Services (DiffServ) approach is intended to provide Quality of Service (QoS) in IP-based networks. This is a very important issue not only in wireline fixed networks but also in IP-based wireless mobile networks. Currently, services within the DiffServ approach including Premium Service, Assured Service and Best-Effort Service are intended for fixed networks. We have proposed the Mobile Differentiated Services QoS model [5] to enhance the above services so they are better suited for wireless mobile networks. One part of this QoS model is the so-called Best-Effort Low-Delay (BELD) Service which has the same low-delay and low-jitter characteristic as Premium Service, but a certain probability for packet loss. This service is especially suited for delay-sensitive and loss-tolerant applications and can take favor of unused Premium Service resources to increase the network utilization. This paper presents details on the BELD Service including initial simulation results showing the feasibility of BELD service.
