Abstract
The standardized approach to Mobile ATM network handover is a hard backward or forward handover scheme with no guarantees for the integrity of the data stream. These handover functions are detailed in this paper and a more performant virtual connection handover protocol, using in-slot signaling techniques in order to facilitate loss less handover, is introduced. The QoS aspects related to this scheme are discussed and its OAM implementation is presented.
Highlights
The broadband service requirements for future generations of mobile communications can be accommodated by high bandwidth ATM networks
Mobile or Wireless ATM consists of two major components: the radio access part which deals with the extension of ATM services over a wireless medium and the mobile ATM part which addresses the issue of enhancing ATM for the support of terminal and service mobility in the fixed portion of the WATM network
These handover functions of a Mobile ATM network are detailed in this paper and a more performant handover protocol, using in-slot signaling techniques in order to facilitate lossless handover, is presented
Summary
The broadband service requirements for future generations of mobile communications can be accommodated by high bandwidth ATM networks. Further research projects and standardization activities coordinated by the ATM Forum demonstrate the feasibility of broadband radio access networks based on ATM technology, which can offer full-scale mobility together with all the range of ATM service capabilities existent in the fixed ATM networks [1]. In order to cope with the requirements of future multimedia applications, more complex solutions, which are including options for QoS control, are needed. These handover functions of a Mobile ATM network are detailed in this paper and a more performant handover protocol, using in-slot signaling techniques in order to facilitate lossless handover, is presented
