The present disclosure is directed to a system and method configured to implement an inter-MSC based handoff of a mobile device between a packet switched network and a mobile core network. In embodiments implementing a handoff from a femtocell to a macrocell, from the perspective of a neighboring MSC on a mobile core network, IP or VOIP information from a femtocell which is in communication with the convergence server, is perceived as having the same protocol as information which originates from a macrocell.

Chunk-based double-dwell preamble detection
In one embodiment, the invention is a method for performing preamble detection in a wireless communication network.

Quality of service for inbound network traffic flows during slow-start phases
An edge network device controls the quality-of-service of incoming network traffic flows by limiting the bandwidth of incoming network traffic flows to create a network traffic bottleneck at the edge network device. The bottleneck ensures that this edge network device may control the quality-of-service of incoming network traffic flows.
