| dc.description.abstract | 本論文提出在手機網路服務上增加另一種隨按即說使用模式，稱為mesh 模式。透過此種模式，使用者可以不透過隨按即說伺服器便可以使用隨按即說服務。我們在本論文中有詳細介紹mesh mode下使用者端的訊息流程。我們重複利用了TBCP做為控制訊息的通訊協定並且針對通話權控制設計一個分散式的機制。我們也透過一個簡單的模型分析群體大小並且透過模擬驗證。Mesh mode的用戶端程式被實作出來而且軟體架構也在本篇論文中展示。 | zh_TW |
| dc.description.abstract | This thesis proposes a mesh mode for Push-to-Talk over cellular (PoC) service. Through the mesh mode, the users can form a Push-to-Talk session without PoC servers. The detailed message flows for PoC client in mesh mode are also defined. We reuse Talk Burst Control Protocol (TBCP) for control messages and provide a distributed mechanism for floor control. Also, we analyze the group size by a simple model and the performance of the proposed mechanism is validated via simulations. We have also implemented a PoC client in mesh mode and defined a software architecture in this thesis. | en |
