Abstract: C+W wireless broadband service is one of the important services which are provided by China Telecom to keep its differentiative competitiveness. China Telecom has confirmed to use the strategy of adapting Wi-Fi to reduce cdma2000 1x Ev-Do networkflow and synergize cdma2000 1x Ev-Do development. However, it is still difficult to establish the association between Wi-Fi hotspots and cdma2000 1x Ev-Do cells accurately and promptly. So an accurate and economic approach to establish this association was reported. Moreover, it had been applied to improve C+W cooperative work successfully. Therefore, not only a most accurate shunt information and suggestion,but also improved distribution efficiency for C+W synergetic development and shunt was provided.
