...International Journal of Computer Applications (0975 – 8887) Volume 8– No.12, October 2010 Handover management in GSM cellular system Jahangir khan School of computer science PAF-KIET, Pakistan Air Force Base korangi Creek Karachi 75190 Pakistan ABSTRACT Handover mechanism is extremely important in cellular network because of the cellular architecture employed to maximize spectrum utilization. Handover is the procedure that transfers an ongoing call from one cell to another as the user’s moves through the coverage area of cellular system. One way to improve the cellular network performance is to use efficient handover prioritization schemes when user is switching between the cells. In this paper I have presented an analytical framework that can enhance considerably the handover call mechanism in wireless network. Some advance schemes namely, guard channels, call admission control and handover queuing are discussed. All these of prioritiztaions schemes have a common characteristic reducing the call dropping probability at the expense of increased call blocking probability. Efficnet prioritiztaion scheme accomadetes a number of new calls while guaranates the quality of sevice(QOS) of hanover call. This idea is based on the neighbouring cells have an ovelapping (the area served by more than one cell) coverage area. Furthermore cell overlap and load balancing scheme is proposed to enhance the GSM cellular capacity using an overlapping coverage area. Capacity enhancement is...

...DESCRIPTION OF THE PROBLEM Handover issues At the start and end of each working Shift operators are expected to hand over the current state of the plant in which they work. They are expected to hand over production issues, health and safety issues and any maintenance work that is being undertaken. They should also be able to hand over the production that is underway and any changes that have been made to the production plan which may effect how they plan there workload. At the moment there are two groups of operators who currently hand over on the plant, they work in the copper and nitrates plants (Nitrates operators do not always hand over on plant). The other operators on site tend to hand over in various places which include the shower room, smoke shelter and weighbridge. Operators also come and interrupt the shift managers during there handover because they are not sure what they are supposed to be doing. To ensure safe handover, organisations should: 1. Identify higher risk handovers; 2. develop staff’s communication skills; 3. emphasise the importance of shift handover; 4. provide procedures for shift handover; 5. plan for maintenance work to be completed within one shift if possible. Scope To introduce a standardised handover for all operators. This will be done on plant and will include all production plans/priorities, health and safety issues and any maintenance work being done or planned. Shift handover should be: 1....

...3.3 CHARACTERISTICS OF HANDOVER Laxmisan et al (2007) conducted an ethnographic study involving analysis of emergency department handover in a US hospital. The study found that interruptions within the emergency department were prevalent and diverse in nature and that there were gaps in information flow due to multi-tasking and shift changes. The communication process is complex and cognitively taxing during and after team handover, that can compromise patient safety. The study also discusses the need to tailor generic electronic tools to support adaptive processes like multi-tasking and handoffs in time constrained environments. Arora et al (2005) conducted interviews using the critical incident technique to handover failures between inpatient physicians in a US hospital. The study interviewed 26 interns and found 25 discrete incidents. The 21 worst events are described. Omitted contents and failure prone communication processes were identified as a major category of failure in communication. These may result in inefficient or sub-optimal care, leading to patient harm....

...Bedside nursing handover: A case study 1. Purpose of the study: The purpose of this study was to identify and describe the structures, processes, and perceptions of the outcomes of bedside handovers in nursing practice. 2. Research design: The authors used a descriptive case study which is a methodological approach that can use a number of different methods to conduct an instrumental investigation that is bounded by place and time. Case study research asks questions of ‘what’, ‘why’, and ‘how’ in a non controlled or non artificial environment to analyse existing, real life situations with all their complexity 3. Sampling technique and characteristics of the sample: The study involved three wards in two hospitals in Australia, thus six wards where ultimately included. Wards that where included where medical, surgical and rehabilitation wards. Team leaders, shift coordinators, nursing managers, and educators where the focus of the study in which all participants gave their consent. A total of 32 female participants where interviewed from both hospitals. No male participants where included. From these participants seven where under the age of 30, ten between the age of 30 and 40, eleven between the age of 40 and 50 and six where aged over 50. with regards to nursing classifications, from the 32 participants, 7 where enrolled nurses, 15 where level 1 registered nurses, 7 where level 2 registered nurses and 5 where level three nurses. Only 16 out of the 32 participants...

...National Quality and Safety Health Service Standard 6: Clinical handover plays an integral part in the transition of patient care between health departments. During Betty's hospital stay, night shift staff did not contact Jane when Betty had a fall. This showed that lack of communication and responsibility was demonstrated between shift change as Jane clearly requested for staff to contact her if there were any changes to her mother's condition. Clinical handover is an essential during medical and nursing practice that occur during different times- between shift changes, between wards and at discharge (Eggins and Slade, 2012). A common issue identified with clinical handover is that information is incomplete or unstructured which may result...

...CHAPTER 1 INTRODUCTION 1.0 INTRODUCTION A handover is defined as “the act of moving power or responsibility from one person or group to another (Oxford Advanced Learner’s Dictionary of Current English 2005)”. In healthcare and clinical context, the term “handover” applies to the transferring of a patient’s information between two health care providers, when the patient receives care in a different location, or when another healthcare provider is responsible of the patient (ACSQHC 2005). The American word “handoff” also signifies the same meaning. Nursing handovers are often being described as a ritual, which stemmed from the medical concept preliminarily in the 1880s, whereby the nursing sister would direct the nurses on duty after hearing reports from the night shift nurses and the doctors’ rounds (Walsh and Ford 1989). The repetitive characteristic of the traditional handover does not encourage nurses to think critically or share different views, therefore depicted as a “ritual” (Kerr et al 2011). 1.1 BACKGROUND OFTHE STUDY The aim of a nursing shift handover is to precisely inform the patient’s general condition, care plan, treatment and expectations in a timely manner (Runy 2008). The process, if made without a systematic standardized method, would lead to errors and jeopardizes patient’s safety (ACSQHC 2010). Reported adverse events from handovers include unnecessary procedure and investigations, delayed diagnosis or treatments, prolonged hospitalization...

...Assessment Task 1: Written Reflection This reflection utilises Driscoll’s “What?” Model of Structured Reflection to consider the application of inter-professional communication in the ‘Pregnant Stroke’ video; “Handover”. Inter-professional communication is defined as clear, quality information that aids in the delivery of excellent health care. (Arnold & Boggs, 2011) Handovers between healthcare workers that use inter-professional practices succeed in providing quality health. In the example video of a handover, the paramedic is telling the nurse the history of the patient that is being transferred to the nurse’s care. The paramedic introduces himself and the patient to the nurse and then delves in to the patient’s history. We find out the patient’s name is sally, a 35 year old pregnant female, who is 28 weeks pregnant. She has a family history on hypertension and stroke, and Sally’s husband, David tells the paramedic that sally is not currently on any medication, and she has no known allergies. David called the ambulance because at breakfast, Sally appeared to faint/ lose consciousness, and David supported her to the ground. Sally did not hit her head on the way down to the ground, and the paramedics found her on the ground when they arrived, and David had made sally comfortable with a cushion. Upon the paramedic’s examination, Sally was found to be hypertensive – her blood pressure was 180/110. Sally showed signs of tachycardia, and had a Glasgow Coma Scale (GCS) reading...

...Réseau d’Accès UMTS Architecture et Interfaces EFORT http://www.efort.com L’UMTS (Universal Mobile Telecommunications System) désigne une technologie retenue dans la famille dite IMT 2000 (International Mobile Telecommunications) comme norme pour les systèmes de télécommunications mobile dits de troisième génération (3G), qui succéderont progressivement au standard actuel : le GSM. L’UMTS permet des améliorations substantielles par rapport au GSM, notamment : • Elle rend possible un accès plus rapide à Internet depuis les téléphones portables, par un accroissement significatif des débits des réseaux de téléphonie mobile. • Elle améliore la qualité des communications en tendant vers une qualité d’audition proche de celle de la téléphonie fixe. • Elle permet de concevoir une norme compatible à l’échelle mondiale, contrairement aux technologies actuelles (les normes utilisées aux Etats-Unis et au Japon ne sont pas toutes compatibles avec le GSM). • Elle répond au problème croissant de saturation des réseaux GSM, notamment en grandes villes. Les technologies développées autour de la norme UMTS conduisent à une amélioration significative des vitesses de transmission pouvant atteindre 2 Mbit/s. De tels débits sont significativement supérieurs à ceux permis par les réseaux GSM actuels (9,6 kbit/s) ou par le GPRS. • Cette amélioration des débits est rendue possible par l’évolution des technologies radio qui autorise une meilleure efficacité spectrale et l’exploitation de bandes de...

In the early days, only the rich and keen early adopters were able to own mobile phones, which were large in size, required a substantial source of power to operate and were limited in functionality and quite restrictive in terms of mobility. Today, over 5.6 billion subscribed devices are in active use, which represent approximately 80% of the world population and are rising. (Gartner) Improved reception power coupled with increased network coverage and penetration, global roaming capability, sharp quality, fitto-palm size with large screen and lightweight are the significants of today’s user terminals. Given such advances, the growth within the large increases of cellular use has been on mobile data. In 2011, the total mobile data service revenues were close to $315 billion (Gartner). LTE is a serious improvement in network architecture to handle this surge in demand and is embraced by all providers. This paper first describes the background of LTE and then outlines the important challenges. Two of the challenges are related to the handover technologies and techniques on providing the required QoS for services, they are discussed...

...of transfer of care is inadequately undertaken risks to the patient are increased and may subsequently lead to harm (BMA, 2005; Joint Commission, 2007). The Network organised a series of patient safety road shows which were specifically designed to build consensus and concentrate activities on the key topic of transfer of care, to facilitate networking between members of the Network’s regional groups and a range of colleagues working across all care sectors, and to identify the actions required to improve the patients’ experience of transfer of care across all health and social settings. 1.1 Literature Review “A good…handover process is a crucial part of providing quality…care…The conservation of patient data during the handover process is vital to ensure good continuity of care and safe practice. Any errors or omissions made during the handover process may have dangerous consequences…” (Pothier, et al., 2005) Delays in transferring or discharging patients can result in a range of problems for both patients and organisations (Bryan, et al., 2005). For patients these problems include: increased dependency; depression; loss of choice, control and confidence; and being placed at risk of exposure to hospital acquired infection. For organisations delays in the transfer or discharge of patients may result in bed blocking, leading to the possibility of greater waiting times for patients needing hospital care and treatment. In addition,...
