中文摘要 | 無線功能附加系統WFAS(Wireless Function Added System)為一附加在用戶交換機上之無線通信系統,其主要應用於提供已購置用戶交換機的使用者一種低價位、小容量的附加無線通信功能。無線功能附加系統在架構上包括:中央控制模組,做為中央控制用;頻道處理模組,做為基地臺控制;類比介面模組,做為類比信號控制用。 當用戶為增加無線功能附加系統下手機的數量而採用多工模式時,由於本系統與公眾電話網路之間受到用戶交換機的阻隔,因此想要和無線功能附加系統管轄下的無線手機通話的使用者,不論來自外線或者是交換機內線,都必須二段撥號,同時也增加通話建立的等待時間。 本論文提出在無線功能附加系統中增加一來方撥號擷取模組可有效的解決上述的二項問題,來方使用者只須記錄一組分機號碼,同時可以降低雙方建立通話的等待時間,使得交換機加上無線功能附加系統之後,不會讓使用者感到不便。 |
英文摘要 | The WFAS (Wireless Function Added System) is a wireless communication system added on PABX, it provides an added wireless communication function with low cost and low capacity for a user bought PABX. The architecture of WFAS includes: (1) Common Control Module (CCM) is used for common control, (2) Channel Process Module (CPM) is used for based station control, (3) Analog Interface Module (AIM) is used for analog signal control. Since wireless handsets and outside telephones are separated by the PABX, a very inconvenient operation called Twice-Segment-Dial and longer connection setup time are required when the connection is established between them. This paper presents a method that adds Dial Signal Fetch Module (DSFM) on WFAS to solve above two problems. To use DSFM, outside telephone users call wireless handset, they operate as no PABX between them. |
