Abstract
This paper develop analytical models for calculating the blocking probabilities of two low layers (picocell and femtocell) of hierarchical cellular networks providing integrated services of mobile users. The analytical models are based on continuous time multi dimensional birth death approach having two layers cellular architecture with reserved number of channels to give the priority to handoff calls. These reserved channels may also be allocated to new calls if reserved channels are free. The two lower layers architecture is based on picocell and femtocell and cellular network consists of two types of subscribers in the system, high mobile subscribers (HMS) and low mobile subscribers (LMS).The channel assignment scheme based on new call bounding, cutoff priority and sub-rating are suggested in cellular network for both type of layers. All the schemes are compared in terms of blocking probability by providing numerical results.
