“…Then we compare the out coming results with completed power control. We will estimate this in a cellar system HAPW-CDMA with multi-functional service, one of the most noticeable advantages of such systems is flexibility, reconstruction features, cheap practicality, having low radiation delay, extended covering [1].…”

Among various radio sources which control different dependencies/functions, in this article, we will talk about the Call Admission Control (CAC), and we are supposed to confine our concentration on W-CDMA which is based on high raised platforms, since during the recent years remarkable amount of attention has been focused on platforms located in stratosphere layer [1]. Firstly, we study the capacity of uplink from HAP (High Altitude Platform) W-CDMA and we’ll work on estimation and power control defects in a new conversation added to current conversations. We’ll enhance the Call Admission Control (CAC) based on the side effects of power control defects and users’ stimulus and then compare the CAC which has been measured by using of momentary energy on bit in the spectral density form (E_b/N₀). Then we examine the mentioned charts for two different criteria which the decision will be made by these criteria in order to decide if exchanged calls are to be admitted or not. The first criterion is based on the minimum of (E_b/N₀) of the first row cells meanwhile the second criterion is based on the average of (E_b/N₀) of first row-cells.

“…In [14], a new CAC scheme for the uplink of a multiservice W-CDMA cellular system is presented that takes into account power control imperfections and user mobility based on Signal-to-Interference ratio (SIR) measurements. In [15], a dynamic power sharing centralized admission control scheme is introduced that aims at guaranteeing fairness among all users in terms of blocked calls per cell.…”

“…the design of an efficient CAC scheme should take into account the channel conditions. The design of efficient CAC schemes for HAP networks has also been dealt with in the literature [12][13][14][15][16].…”

In this paper, a new cross-layer design is proposed employing the predictability of rain faded channels to guarantee QoS requirements in High Altitude Platform (HAP) networks. Both a centralized and a distributed scheme are proposed for call admission control of packet-switched HAP wireless networks using a cross-layer approach aiming at keeping the call dropping probability below a predefined threshold. In both schemes, a new call is accepted if there are sufficient resources for the ongoing calls and for the new one to guarantee their QoS requirements for their whole connection. The performance of the proposed schemes is investigated using markov chain analysis and bounds of the call blocking probability are determined analytically.
