UMA(GAN)發展歷程

說明：UMA又稱為GAN

2004 UMA Technology Group由許多營運商以及網路供應商所共同發起。

2005 UMA轉移到3GPP的GERAN R6，成為GAN。初期文件對應到TS 43.318與TS 44.318。

2005 The first service launch was British Telecom with BT Fusion in the fall of 2005. The service is based on technology which is pre-3GPP GAN standard. Initially, BT Fusion used UMA over Bluetooth with phones from Motorola; since Jan 2007, it uses UMA over Wi-Fi with phones from Nokia, Motorola and Samsung and is branded as a "Wi-Fi mobile service".

2006 3GPP GERAN R7制訂GAN手機的符合性測試規範：TS 51.010-1 v7.x.0。

2007 Agilent 8960首先支持GAN測試功能。其初期方案是以一個電腦，在其上面執行一個稱為GANC的軟體，透過LAN同時與一個AP以及Agilent 8960聯接起來，執行非TTCN的GAN行為模擬測試。

2007 在安捷倫研討會筆者提問是否有人談論將WiMAX納入GAN的架構，答案是還未聽說。
