A Comparative Analysis of Vertical Handover Decision Process Algorithms for N...Editor IJMTER
Increasing consumer demand for access to services anywhere and anytime is driving a
hastened technological progression towards the integration of a variety of wireless access
technologies. Therefore one of the chief interest points of Next Generation Wireless Networks
(NGWNs), refers to the capability to support wireless network access equipments to guarantee a high
rate of services between dissimilar wireless networks. To answer these problems it is essential to
have decision algorithms to decide for every user of mobile terminal, which is the most excellent
network at some point, for a service or a precise application that the user needs. Therefore to make
these things, many algorithms use the vertical handoff technique. A series of algorithms based on
vertical handoff technique with a categorization of the different existing vertical handoff decision
strategies, which tries to resolve these issues of wireless network selection at a specified time for a
specific application of an user has been discussed in this paper. Also few parameters that are to be
considered during vertical handover have been discussed briefly.
An electric circuits' remote switching system based on gsm radio networkeSAT Journals
Abstract Mobile phone industry is classified among the fastest growing engineering branches. It has to be exploited for vast applications, reliability and affordability. Mobile cellular phone subscribers have reached saturation point; with such information, the basic cell phone that was mainly utilized to make calls will also be utilized for remote switching and control activities. The now developed system is based on the global system for mobile communications (GSM) radio network: it will operate as a very long distance remote switch. Utilizing the daily cell phone, a user will either put on/off any desired electric circuit located in an owned, controlled compound. Two cell phones are provided, one being a mobile transmitter user end and another being referred to as a fixed receiver end. A signal will be sent from the user end to put a consumer’s electric circuit either on or off at the receiver end; afterwards, the receiver end will notify the user-end about the on/off state of the consumer. The particularity of this publication is the system simplicity, yet cheap and safe, so that even very low income cell phone users can enjoy radio frequency (RF) technology’s increasing applications. The software utilized to develop and simulate circuits is the linear technology, LT spice. The calculative theory has quantitatively enriched the methodology. Both the building blocks and the physical implementation diagrams for the system are herein contained. The remote switching system based on GSM radio network has been successfully designed, implemented, tested and its functionality has been examined.

UNIT III MOBILE TELECOMMUNICATION SYSTEM
Global System for Mobile Communication (GSM) – General Packet Radio Service (GPRS) – Universal Mobile Telecommunication System (UMTS).
The GSM standard was developed by the Groupe SpecialMobile, which was an initiative of the Conference of European Post and Telecommunications (CEPT) administrations.
The responsibility for GSM standardization now resides with the
Special Mobile Group (SMG) under the European Telecommunication Standard Institute (ETSI).
Fully digital system utilizing the 900MHz frequency band.
TDMA over radiocarriers(200 kHz carrier spacing)
8 full rate or 16 half rate TDMA channels per carrier
User/terminal authentication for fraud control
Encryption of speech and data transmissions over the radio path
Full international roaming capability
Low speed data services (upto 9.6kb/s)
Compatibility with ISDN for supplementary services
Support of short message services(SMS)
GSM supports a range of basic and supplementary services, and these services are defined analogous to those for ISDN(i.e.,bearer services, teleservices, and supplementary services).
The most important service supported by GSM is Telephony.
Other services derived from telephony included in the GSM specification are emergency calling and voice messaging.
Bearer services supported in GSM include various asynchronous and synchronous data services for information transfer.
Teleservices based on these bearer services include group 3 fax and short message service(SMS)
The data capabilities of GSM have now been enhanced to include high speed circiut-switched data(HSCSD) and general packet radio service (GPRS).
Call offering services call forwarding
Call resrtiction services call barring
Call waiting service
Call hold service
Multi party service tele conferencing
Calling line presentation restriction services
Advice of charge service
Closed user group service
The GSM System comprises of Base Transceiver Station (BTS), Base Station Controllers (BSC), Mobile Switching Centers (MSC), and set of registers (databases) to assist in mobility management and security functions.
All signaling between the MSC and the various registers (databases) as well as between the MSCs takes place using the Signaling System 7(SS7) network, with the application level messages using the Mobile Application Protocol (MAP) designed specifically for GSM.
The MAP protocol utilizes the lower layer functions from the SS7 protocol stack.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

6. Mobility Management
Mobility management is one of the major functions of a GSM or
a UMTS network that allows mobile phones to work. The aim of
mobility management is to track where the subscribers are,
allowing calls, SMS and other mobile phone services to be delivered
to them.

8. Addressing
• An IP address is a unique numerical value that is used to identify
a computer on a network.
• There are two kinds of IP addresses:
- Public
- Private
13. This figure shows the basic soft handoff process that occurs in the
IS-95 CDMA system. In this example, the mobile device has
measured the signal strength of the pilot channel from a nearby
cell site. Using this information, it is determined that the adjacent
cell site is a candidate for the soft handoff process and that is
should simultaneously communicate with the mobile device and
the soft handoff process begins. During the soft handoff process,
information from the mobile device is simultaneously received by
both cell sites and the information frames that have the highest
quality (least errors) can be selected.
