Before revision:  The quantitative results illustrate that, for example, as more shared channels are used for load balancing an increase in overall system channel utilization is observed. However, more interestingly, the improvement in blocking probability per shared channel for load balanced users  is maximized at an intermediate number of shared channels  as opposed to the maximum number of these shared resources.
After revision:  The quantitative results illustrate that, for example, cellular network operators can control the manner in which traffic is offloaded between neighboring cells by simply manipulating the length of the random access phase. Our analysis allow to quantitatively determine the blocking probability individual users will experience given a specific length of random access phase. Furthermore, we observe that the improvement in blocking probability per shared channel for load balanced users is maximized at an intermediate number of shared channels as opposed to the maximum number of these shared resources.
