dc.description.abstract | 在IEEE 802.16無線寬頻網路中,較大的傳輸距離與具備服務品質的通訊技術,將會對未來的網路使用型態帶來重大改變。由於行動通訊與即時影音服務的需求增加,IEEE802.16e被提出來以針對使用者移動性的支援。當一個移動節點(Mobile Station)從一個基地台移動到另外一個基地台時,會啟動一個連串的換手流程(handover process),換手是影響行動通訊中服務品質的一個重要因素。
在本論文中,將提出新的換手流程訊息傳遞方式,使用預先配置(pre-configuration)的機制,讓使用者在換手斷線前就預先取得新的連線ID,並且透過基地台間的負載平衡,降低換手可能遭遇的服務阻斷率(dropping rate),藉此兩種方式來降低換手延遲(handover latency)。 | zh_TW |
dc.description.abstract | In IEEE 802.16 wireless broadband networks, the long transmission range and the telecommunication technique of service quality will bring major change to the future network use pattern. Because of the increasing demand of mobile communication and real-time video service, IEEE 802.16e is further proposed to support mobile users. When a mobile station moves from a base station to another base station, it will conduct hard handover process. Handover latency is an important factor which influences the service quality in the mobile communication.
In this thesis, we will propose a novel information delivering technique for the process of hard handover process. This technique let user obtain a new connection ID to start the handover process by using the concept of pre-configuration. We also reduce the service dropping rate by balancing the loads between base stations. As shown in the simulation results, the proposed approach making use of these two techniques can reduce the handover latency. | en |
