“…There are very little works on the development of tools required for the development of network management systems needed to manage networks that encounter handover events such as GSM networks. Varied solutions exist for the reduction of the handover probability, handover rate and handover time in GSM, asynchronous transfer mode (ATM) and satellite networks where resource partitioning algorithms were proposed [10,11,12,13,14]. Guard channel reservation strategies have been shown to be very effective in the reduction of handover call drop rate while assuring high level resource utilization [15,16].…”

The increase in GSM mobile station (MS) density, without a corresponding increase in radio channel resource capacity, reduces the quality of service (QoS) standard provided to users. Attempts to improve the QoS standard usually leads to the creation of new base stations (BS) with the consequent reduction in the existing cell sizes. Although, the available network capacity is increased, this happens at the expense of increased numbers of call handoversSuch increase is usually accommodated by resource reservation. How well the reservation is made greatly influences the GSM network quality of service (QoS) and the general BS resource utilization. This work presents a radio channel resource reservation technique for GSM handover calls. A typical GSM network architecture was modeled using an integrated modeling technique in a MATLAB block oriented simulation environment. The analytical part of the model was developed using the Markov chain principle and validated using the existing popular Lee's queuing model. The relationships between the handover call blocking probability, fresh call blocking probability, the number of resources to be reserved and traffic intensity were established. Simulation results were analyzed and a method of determining the optimum number of resources that can be reserved for handover calls for a given BS resource capacity was presented.

“…To support network-wide handoff, new and handoff call requests will compete for connection resources in both the mobile and backbone networks. Handoff calls require a higher congestion related performance, i.e., blocking probability, relative to new calls because forced terminations of ongoing calls due to hand-off call blocking are generally more objectionable then new call blocking from the subscriber's perspective [5], and [14].…”

This paper focuses on the problem of congestion control in wireless ATM network. This is a practical fact that frequent handoff in Personal Communication Network (PCN) introduces the phenomena of congestion. After studying the currently used schemes, it is clear that there is some room for improvement for conventional handoff ordering schemes. A new Hybrid Scheme [Gupta et al., 2006] proposed by the authors to solve the hand off/ hand over problem in ATM-based PCN, which aims to give handover calls high priority over new calls. When reservation is applied on both radio and backbone channels, it leads to significant decrease in Forced Termination Probability (FTP) with acceptable increase in Call Blocking Probability (CBP). Since the number of resources is limited (i.e. radio channels) as more channels are assigned to serve handover request, blocking probability will increase, which is obvious. Comparative simulation study carried out to show how improvement is achieved by using the Hybrid Scheme in comparison to the other schemes like First-In-First-Out (FIFO) and Measurement Based Priority Scheme (MBPS) [Tekinay & Jabbari, 1992]. The improvement reflects remarkable reduced percentage of FTP due to handover failure, when we use our proposed Hybrid Scheme.

“…In this paper, we will take an ATM network as a backbone and combine it with a wireless network. Based on this network, we will propose a new handover protocol that can support a high handover rate [20] and handle cell loss and cell out of sequence in a micro and nonoverlapping cell environment.…”

Wireless information networks need to employ small radio cells to support large user populations. However, this will impose extra burden on network traffic control as a result of frequent handover behavior. Existing approaches to support a high handover rate still have cell loss and cell out-of-sequence penalty while the handover is in progress. This paper proposes a novel handover protocol that can avoid cell loss and guarantee cell sequence. It can enhance the performance of a microcellular asynchronous transfer mode network. By multicasting cells to a new base station before handover, our scheme can avoid cell loss and support a nonoverlapping microcell environment as well. The multicast of signaling messages during handover is to coordinate the cell transmission order between the old base station and the new base station to guarantee cell sequence. A formal representation of the handover protocol using finite-state diagrams has been developed to specify and verify the protocol. To guarantee quality of service, we present a hierarchical wireless call admission control to limit the number of in-progress connections and to prevent radio channel congestion. Mathematical models have been developed to analyze two quality-of-service parameters: handover dropping probability and forced termination probability. Experimental results show that our hierarchical wireless call admission control can effectively lower the handover dropping probability and the forced termination probability in comparison with the single-layer wireless call admission control.
