WiBro Network Management Issues


Progressing WSM IssuesProgressing WSM Issues

- Mobile CPE and Fixed CPE Management Issues- CPE Performance/Fault Management- CPE Auto Configuration / Remote Download Management

CPE Management

- WSM also has to support more practical and various QoSManagement FunctionsQos Management

- WiBro will be supporting Voice Service.- WSM has to support Voice Quality Management FunctionsVoIP Management Support

- IPv6 is preparing to adapt in practical site.- IPv6 has to be used to give each CPE unique address.- IPv6 Management Functions have to be applied to WSM

IPv6 Support

- The main feature of WiBro is supporting Mobility.- Mobility Parameters have to be controlled in the same time to whole

network elements.- WSM internetworking for Mobility Parameter sharing is not exist.- WSM could communicate among other WSMs which have a relation

for Mobility Parameters.
