摘 要: | 为了更好地评估分析ETC业务在GSM/UMTS现网上的适应承载性,文章首先建立了ETC三层业务源模型,并结合相应的模型对ETC和传统H2H业务共存于GSM/UMTS网络场景下的接入性能分别进行评估分析。仿真结果表明,ETC业务能够在不明显影响H2H业务接入性能的条件下,较好地承载在现有GSM/UMTS网络上。另外,仿真结果表明多流业务场景2与多流业务场景1相比,能够更好地承载ETC业务,对实际应用有着很重要的指导价值。

Abstract: | To better assess the evaluation of ETC on the existing GSM/UMTS network, a three-tier traffic model is established at fh-st, and then the random access performance of ETC and the tradi-tional H2H for ETC and H2H co-existing scenario is evaluated according to the established traffic model. The results indicate that ETC can be carded on the condition that traditional H2H communica- tion isn't affected severely. In addition, it can be found that compared with the multi-flow traffic ap- plication scenario 1, the multi-flow traffic applica-tion scenario 2 is better able to bear ETC service, which has a significant guidance value for practical application. |
