摘要
研究了异构网环境下多维马尔科夫建模问题。以UMTS和GSM/EDGE异构网为例,建立了一个四维马尔科夫模型,并通过降维和迭代得到其数值解,进而得到各子网和异构网的拥塞率、交通量、负载量和吞吐量。为进一步研究异构网环境下的接入选择问题建立了基础。
Multidimensional Marcovian model in the environment of heterogeneous network is investigated. A 4-D Marcovian model is built based on a heterogeneous network integrated with UMTS and GSM/EDGE as an example. The numerical solutions are obtained using the methods of dimension-decrement and iteration, and more over, the block probability, traffic , load and throughput of the heterogeneous network, as well as its sub-networks, are also obtained. These form the basis of next step＇ s research to the access selection in the heterogeneous networks.
