- Abstract
- Four methods of mobile IP (MIP) registration, call admission control (CAC), L2/L3 mobility and DiffServ mapping are mentioned for QoS assurance according to the admission of four classes of services as unsolicited grant service, real time polling service, non-real time poling service and best effort service in WiBro implementation. At operator's first implementation stage, QoS assurance method of only L2 mobility is applied with QoS parameter and scheduling function of CAC, here CAC factors are maximum/minimum bandwidth and traffic priority. At operator's second implementation stage, QoS assurance method of L2 and L3 mobility is applied with QoS parameter of CAC and scheduling function of its CAC. Here, CAC factors are maximum/minimum bandwidth, traffic priority, maximum delay and tolerated jitter. Finally, at the third implementation stage of operators, QoS assurance for nrtPS and rtPS rtPS service class are almost same as second implementation stage, but operator will strength QoS manager functions compare to previous stage for more accurate QoS assurance. © Springer-Verlag Berlin Heidelberg 2006.
