2. Description of the Related Art

Wireless communications comprises a wide range of technologies, services and applications that have come into existence to meet the particular needs of different market sectors and user environments. Different systems can be broadly characterized by:

    • content and services offered;
    • frequency bands of operation;
    • standards defining the systems;
    • data rates supported;
    • bidirectional and unidirectional delivery mechanisms;
    • degree of mobility;
    • regulatory requirements; and
    • cost.

The service requirements for telecommunications remain the following characteristics:

    • Speech and SMS (Short Message System):
    • This service type requires a peak bit rates up to 16 kbps. In the year 2010 onwards, there will still remain needs for these very low data rate applications of speech and simple message service. In addition to that, some applications in the field of sensor communication and/or low bit rate data telemetry would also be expected for the category, as ubiquitous communications. Most of mobile e-commerce applications would also be categorized in this type.
    • Multimedia and Low Rate Data:
    • This service type at a data rate of less than 144 kbps should also be considered, taking into account the compatibility with 3G and 2G data communication applications.
    • Medium Multimedia:
    • This type support a peak bit rate of up to 2 Mbps. This type would be required to sustain the compatibility with the 3G applications.
    • High Multimedia:
    • This type should be considered in order to accommodate high data rate applications, including multi-media video streaming services, which are provided with broadband service in fixed wired communication systems or with broadband wireless access systems.
    • Super High Multimedia:
    • This type should also be considered in order to accommodate super high data rates multi-media applications, which are currently provided with Fibre-to-the-Home (FTTH) services in case of wired communication systems. Currently, these services require different communication devices with different connection facilities that the users need frequent switch between various terminals at home, office and in other environments.

A service usage pattern may be categorized according to an area where users exploit similar services and expect similar quality of service:

    • Home
    • Office
    • Public area
    • Wide area

In many countries, wireline Internet access in Home, Office and Public Area becomes very popular and affordable. Meanwhile, WLAN (wireless local area network) access is evolving rapidly in these domains.

Mobile communications have evolved rapidly on the worldwide basis. But when we look back at the wireless mobile communication history, two major issues remain unsolved:

    • 1. The mobile wireless terminal architecture is too closed.
    • 2. The mobile wireless terminal system is too complicated.
    • 3. The mobile wireless services are too carrier-centric, not user-centric.

The wireless transmission theory of our research tells us that no single wireless transmission technology can provide both broadband high-speed radio transmission and seamless fast mobility capability in a mobile fast-fading propagation model environment unless we reduce the mobile network capacity tremendouslyreferred to as LU's Laws in the industry.

Our research shows that when the transmission bandwidth is enough, the information processing consumes much more resources and energies than the transmission processing.

In order to solve the above two problems in mobile communications, let us analyze the current situations first.

In many countries, wireline Internet access in home, office and public area becomes very popular and affordable. Meanwhile, WLAN (wireless local area network) access is evolving rapidly in these domains.

Second generation (2G) wireless mobile systems were mainly designed for applications such as voice. Third generation (3G) and especially, fourth generation (4G) mobile system will increasingly be designed as combination of different access technologies to complement each other in an optimum way for different service requirements and radio environments in order to provide a common and flexible service platform for different services and applications.

Access to a service or an application may be performed using one system or may be performed using multiple systems simultaneously or alternatively. Specifically, as will be described within the context of the present invention and has not been addressed in the art, such improved technology could include an integrated and converged communication system which will combine the wireless mobile communication, wireline communication, wireless local area network, broadband wireless access system and Internet into one common platform so that the single Mobile Terminal can operate as a home phone, office phone, mobile phone and open terminal with single user number, which is the unique identifier of this integrated mobile communication terminal.

In future, operators may deploy a mix of technologies that could, at various stages in time and subject to market and regulatory considerations, incorporate cellular, WLAN (wireless local area network), WMAN (wireless metropolitan area networks) or called BWA (broadband wireless access), WPAN (wireless personal access network), digital broadcast, satellite and other access systems as discussed by the present invention. This will require the seamless interaction of these systems in order for the user to be able to receive a variety of content via a variety of delivery mechanisms depending upon the particular terminal capabilities, location and user profile.

Different radio access systems will be connected via the open and flexible core networks. In this way, an individual user can be connected via a variety of different access systems to the networks and services he desires. The integration and convergence between these different access systems in terms of horizontal and vertical handover and seamless service provision with service negotiation including mobility, security and service quality management will be a key requirement.

Due to the different application areas, cell ranges and radio environments, the different access systems can be organized in a layered structure similar to hierarchical cell structures in cellular mobile radio systems. The different layers correspond to the:

    • Distribution layer: This layer comprises digital broadcast type systems to distribute the same information to many users simultaneously through unidirectional links.
    • Cellular layer: The cellular layer may comprise several cell layers with different cell size and or different access technologies.
    • Hot spot layer: This layer may be used for very high data rate applications, very high traffic density and individual links, e.g. in very dense urban areas, campus areas, conference centers, and airports.
    • Personal network layer: Personal area networks will support short range high-speed direct communication between devices around the users.
    • Fixed (Wired) layer: This layer includes any fixed wireline access system.

Such an integrated mobile terminal system as provided by the present invention could intelligently converge mobile communications, Internet, wireline communications, wireless LAN, wireless MAN, wireless PAN, etc into an open system platform. Each of these represents a variety of applications, services and delivery mechanisms. These differing information flows are desired by the users to be available regardless of the means and manner of delivery. The most important is, this mobile terminal becomes the All-in-One common personal communicator at both home and office or on-the-move with unified single telephone number.

It is well predicted that 2G (second generation), 3G (third generation in its present state), 4G (fourth generation), future mobile access and nomadic/local area wireless access elements are considered to be a system as a whole in the future. This converged and integrated communication platform as disclosed by the present invention, rather than separate and single mode of standard, will definitely drive the future telecommunication industry, but with new business model for service providers and operators.
