隨著科技的發展,行動通訊系統快速的成長,GSM系統已經充斥整個市場。但是,GSM系統無法提供符合人類需求的資料服務,進而提出GPRS系統。GPRS系統可從GSM系統研展而來,可以提供封包資料服務。
但是,因為速度以及頻寬,GPRS系統依然無法滿足人們對多媒體的需求,所以,人們對3G系統趨之若鶩。3G系統似乎已經在無線多媒體上提供完美的解,但是,由於3G系統的複雜度以及3G上的缺少應用服務,所以,3G系統一直遲遲未推出。
反觀無線區域網路802.11已經發展良好,而且能提供高達11Mbps的速度,適合多媒體的傳輸,架設也相當容易。所以,為了減少對3G系統的依賴以及能及早提供一個適合多媒體傳輸的行動通訊網路,我們提出將GPRS蜂巢式網路與無線區域網路802.11結合起來,成為一個整合性的網路。並且希望能以相同的行動設備來存取這整合的網路。
為了提供服務品質,我們分別在GPRS上提出有服務品質的GPRS(QGPRS)以及在無線區域網路上提出全預留階層式頻寬預留通訊協定(FRHMRSVP),並且進一步將QGPRS與FRHMRSVP結合起來,成為一個提供整合性服務品質的整合網路。
此外,我們還提出了在GPRS網路上提供服務品質的實做方式,此實做方式並不是唯一的方法,但我們提供了一種可能性及方式,並且我們已經在工研院電通所的GPRS測試平台中,實做出我們所提之排程機制以及頻寬溝通程序,並且已經證明,在GPRS系統中加入排程機制可以有效的提供服務品質。

With the development of high technique, the mobile communication systems increased rapidly. The GSM system has already widely-deployed. Because of low data rate, the GSM can not satisfy customers in terms of data services. The GPRS system is an evolution of GSM system. The GPRS system can provide packet data services over the currently well-deployed GSM infrastructure.
Because of low data rate and low bandwidth, the GPRS system can not satisfy customers in terms of multi-media. In order to provide high bit rates access and high bandwidth, the 3G systems are emerging. The 3G system seems to be the solution to the wireless multi-media networks. Because of complexity of 3G system and the lack of kill application, we don’t know exactly when the 3G system is available.
On the other hand, the WLAN 802.11 has been well-developed. WLAN can provide over 11M bps which suitable for multi-media and the environment can be configured easily. So we proposed the Integration of WLAN 802.11 and GPRS cellular networks. That, we can access different networks with the same mobile device seamlessly.
In order to provide guaranteed QoS, we proposed the QoS GPRS (QGPRS) and Full-Reservation Hierarchical Mobile RSVP (FRHMRSVP) on GPRS and WLAN respectively. Furthermore, we combined QGPRS with FRHMRSVP. We expect the integrated network can provide integral QoS.
Besides, we also proposed a way of implementation to provide guaranteed QoS on the GPRS networks. This implementation is not the only way. We provided a possible solution. We have already implemented the Scheduling Mechanism and Bandwidth Negotiation Procedure on the ITRI/CCL GPRS simulator. We have demonstrated the scheduling mechanism and proved that the scheduling mechanism on GPRS can provide the QoS obviously.
