Mobile communication is consistently one of the hottest areas that are developing at a flourishing rate, with advanced techniques appearing in every the fields of mobile and wireless marketing communications. Current times are just the beginning for deploying 3G mobile communication systems, hike research on the next generation of mobile communications, 4G Cordless and mobile sites get started to pave just how for the future. This paper studies the visions of 4G from a complex perspective. After a short review on the development background and position of mobile marketing communications and related 4G perspectives, present an overall 4G feature construction based on the kernel
concept of integration, in hitch to key features (variety and adaptability) of the three targets (terminals, systems,
and applications) are identified at length. The principles of both exterior and
internal diversity of each target are defined to illustrate the causes and
solutions of the flexible feature. Then, along the complete 4G domain, each feature in the construction is deeply talked about from a specialized standpoint, in which appealing techniques and possible research issues for sufficient support of adaptability are also proposed. Finally, a brief summation on 4G visions is shown as a continuum of features in the development of the mobile communications world. In such a technology, we go in for a new motive in order to help the deaf visitors to communicate as efficiently as the normal human being. This may be well attained by means of bringing out new software called the words to text converter (VoTC).
Mobile communications and wireless networks are growing at a fantastic quickness, with evidences of significant expansion in the regions of mobile clients and terminals, mobile and wireless access sites, and mobile services and applications. The present time is merely right to get started on the research of 4G mobile communications because of
Possibility, in line with the historical indication of the generation trend once ten years, and now we are near the end of 3G standardization stage and the beginning of 3G deployment.
Necessity: according to 3G goals, 3G is essential however, not sufficient to the mobile communication strategy, in which many problems are only partly fixed and there are still many problems left to be fixed within the next era, i. e. 4G.
1) Many of the related 4G research focuses mainly on one specific technological area, such as sent out computing, mobile agents, multimedia services, or
radio air interfaces, etc.
2) Some pieces of research are interested
mainly in 4G situations from the standpoints of company or individual, or market analyst, from a less or non-technical viewpoint.
The difference of this newspaper to other related pieces of research is that we are going to present overall visions on the top features of 4G mobile marketing communications, based on an attribute framework and offer in depth proposals to respected support techniques and research matters.
This newspaper is organized the following. Another section includes a brief review in the development background and status of mobile marketing communications, as well as an evaluation of the problems of 3G and producing trends summarized. The next text message is comprised with, following a review of related 4G perspectives, we present a standard 4G feature platform based on the main element concept of integration, and then explain each of the two features (variety and adaptability) of the three relevant focuses on (terminals, networks, and applications) at length. The heart of this paper deeply talks about the adaptability feature of each three focuses on in the whole 4G domain name from a technological standpoint, where promising techniques and possible research issues are proposed. The skeleton of the paper understands a short summation on 4G visions. The declining part concludes the paper.
A. 4G Feat desire Framework
We summarize our proposal of 4G features with one word, or higher simply, with one expression: integration, i. e. smooth integration of terminals, sites, and applications (as well as users). A far more detailed analysis and description of this is is as follows.
1) The discussion domain name includes three relevant targets, i. e. terminals, networks, and applications. Out of the 4G domain, an individual is the one target.
2) The kernel phrase of the definition is so-called integration, this means the convergence of first the three different goals; second the many modes of every goal, which lead to the feature of variety.
3) The modifier "seamless", which means the type and dependence on integration, signifies the support of the adaptability feature between your three targets, each one of which is largely miscellaneous.
external diversity and internal variety.
External diversity is beyond your aim for, which brings along the demand of the adaptability feature to all or any targets.
Internal diversity is inside each of the targets, and it serves as the answer for adaptability requirements.
In short, the need for adaptability is induced by external variety, which is solved by inside diversity. Here both the external and inner variety of users will be the reason behind all adaptability requirements, which implies that the user is out of the technical area of 4G visions. Both main features. I. e. diversity and adaptability of the three focuses on terminal, network, and application are described in detail in the next section.
B. 4G Feature Description
1) User Variety: The external diversity of users, i. e. people in several situations, includes e. g. culture, educational backdrop, economic capabilities, physical property, personal preference, etc. The inner diversity of users, i. e. people with different interfaces, include e. g. eye-sight, hearing, talk, touch sense, fingers and hands, body, etc.
Note that as for users, both their exterior and internal variety are to be designed by the other two goals: terminal and software. Additionally, for adapting the two kinds of end user diversity, both external and interior diversity of terminals and applications are the solution.
2) Terminal Variety and Adaptability: The terminals' exterior diversities will be the differences of terminals in both
static and mobile qualities. Static capabilities include e. g. operation, weight, size, power supply life, human user interface, antenna, processing potential, security, style, and cost. Mobile traits include dynamic characteristics of both temporal and spatial features. The previous category contains e. g. moving rate and acceleration, along with stationary, pedestrian or vehicular attributes, while the second option is connected to spatial range, e. g. indoors, on-campus, in urban and rural conditions, and also path. The internal variety of terminals means that certain terminal may integrate multiple functions, methods, interfaces, flexibilities, etc.
There are three targets for terminal adaptability. For users, it includes the provision of different terminals to gratify different users and an individual user's various requirements. For applications, hopefully that miscellaneous services can be delivered to a unitary terminal. When networks are concerned, an individual terminal can reach a variety of systems despite of location and mobile rate.
3) Network Diversity and Adaptability: The exterior variety of networks is obvious. Internet is assorted naturally, while wireless systems keep the same property. For example air interfaces can integrate all types of standards and work on different frequencies. Moreover, multiple providers deploy sites with multiple requirements and protocols. The internal diversity of sites means any particular one network can interconnect with other different systems and copy various varieties of lots, e. g. cellular systems with various coverage.
Three targets are related to network adaptability. In mention of terminals, network adaptability aspires to make multiform mobile devices with an array of moving speeds and mobile areas connectable to cordless systems. For applications, there's a need that any type and/or quality of service can be provided through diverse predetermined and mobile systems in the best option and successful way. The target for systems themselves is to make it easy to create a 40 feature platform in order to be transmitted effectively and effectively.
We present the support techniques for every single of the aforementioned features in the next forthcoming text.
D. 4G Complex PERSPECTIVE
It is clear that 4G, exactly like all the previous generations, is powered not only by technology, but also by market requirements. This section mainly discusses, from a more technical point of view, possible issues for research and appealing techniques of 4G, and focuses mainly on those techniques that give support to the primary feature of adaptability by inside diversity of focuses on in the 4G domain. Fig. 2 offers an illustration of the discourse domain name of 4G. Complex details are dismissed here because of the length limitation of the newspaper. The various likelihood of competition among services are illustrated above.
1) End user interfaces of terminals vary from traditional keyboard, display, and tablet, to new interfaces predicated on Lasers
Speech, touch, vision, soft switches, etc. This may be common at the same time when one terminal has multiple user interfaces.
2) Adaptive techniques such as smart antennas, software radio, and smart transceivers, enhance interoperability through simultaneous support of several radio interfaces in a single terminal. This makes a terminal roam able across any air interface standard and connectable to any cordless gain access to point by exchanging settings software. These techniques can be used on cellular access things as an advanced smart base station.
3) Terminals will be aware of location and context, often predicated on some wireless low power receptors that are individual- delicate and/or environment-sensitive to be able to keep an eye on and connect to the physical world to article the human being and/or environmental factors. The advancements in this area have been used in e. g. wearable computer systems as a book terminal type.
4) An intelligent terminal can dynamically improve its processing capability to be able to contain various services. Some function modules could even be downloaded to a terminal when needed.
1) Smart antenna, software radio, together with advanced base stop will be the key ways to achieve adaptability of cellular access issues to diverse terminals, i. e. to make radio systems and air sites re-configurable.
2) Hierarchical and ubiquitous as well as overlay mobile systems, including Pico cell, micro cell, macro cell, and mage cell ones, put into practice seamless network interconnection of both symmetric and asymmetric nature, and seamless terminal handoff of both horizontal and vertical levels respectively.
3) Network part hierarchical ability to move management based on Mobile IPv6 and Cellular make systems portable and versatile of self-deployed wireless networks to present this idea IP brings quick and smooth handoff to terminals. The Mobile IPv6 also reveals a great contribution to the adaptability of heterogeneous sites.
4) Random wireless networks are a sort, and therefore dynamically show unlicensed radio spectrum
4G Mobile Communications
5) Network reconfiguration can be obtained by the reconfiguration of protocol stacks and programmability of network nodes. Thus, it can adjust dynamically to the changing route conditions and low or high data rate users.
6) Miscellaneous services can be provided through an assortment of transmission sites including unicast, attribute, importance, bandwidth demand, or data stream type, multiple
levels of Quos can be identified for various services.
multicast, and broadcast ones. According to the service types, e. g. real-time
7) Network source of information can be dynamically
allocated to cope with varying traffic insert, route condition, and service environment. Traffic conditions will be dynamically supervised and handled via techniques such as sent out and decentralized control of network functionalities.
1) Mobile request should refer to a user's profile so that it can be supplied in ways most preferred by the customer, such as context-based personal services. This also brings the applications with adaptability to terminals that are relocating varying locations and speeds. Micro-sensors and Gps unit receivers are the main driven techniques.
2) Techniques such as adaptive multi-media and unified messaging take the terminal characteristics into account and ensure that the service can be received and operate on a terminal with appropriate form to the sponsor type.
3) Intelligent mobile software agent is a common strategy to all of the three goals, which become a platform for service development, delivery, and auto-configuration.
4) Applications can make a deal with networks so that they can be transferred with efficient channel, e. g. interior systems or WLAN or cellular systems in a wide area. Services will be tailor able to be able to fit different network environments and the varying traffic conditions.
5) Services and applications may also be smoothly
delivered across a multiple area of operators and service providers.
