Accordingly to maintain battery life, measures were introduced into many of the designs to ensure the optimum efficiency. This is considerably more complicated than that used in phones for previous generations. Again this has been optimised to reduce the current consumption as far as possible.

With users expecting the same lifetime between charging batteries as experienced on the previous generation phones, this has necessitated the use of new and improved battery technology.

Now Lithium Ion Li-ion batteries are used. These phones to remain small and relatively light while still retaining or even improving the overall life between charges.

This is a more advanced version of the SIM card used in GSM and other systems, but embodies the same types of information. Other information that the USIM holds includes the preferred language to enable the correct language information to be displayed, especially when roaming, and a list of preferred and prohibited Public Land Mobile Networks PLMN.

The USIM also contains a short message storage area that allows messages to stay with the user even when the phone is changed.

Similarly "phone book" numbers and call information of the numbers of incoming and outgoing calls are stored. The UE can take a variety of forms, although the most common format is still a version of a "mobile phone" although having many data capabilities.

Other broadband dongles are also being widely used. In view of the far greater number of applications and facilities that it can perform, the decision was made to call it a user equipment rather than a mobile. However it is essentially the handset in the broadest terminology , although having access to much higher speed data communications, it can be much more versatile, containing many more applications.

It consists of a variety of different elements including RF circuitry, processing, antenna, battery, etc. One of the major challenges for the RF power amplifier was to reduce the power consumption.

These inherently take more current than non linear amplifiers which can be used for the form of modulation used on GSM.

3G UMTS Network Architecture

This is a more advanced version of the SIM card used in GSM and other systems, but embodies the same types of information. UMTS Universal Mobile Telecommunication System will offer a consistent set of services to mobile computer and phone users no matter where they are located in the world.

Based on the GSM Global System for Mobile communication communication standard, UMTS, endorsed by major standards bodies and manufacturers, is the planned standard for mobile users around the world by Today's cellular telephone systems are mainly circuit-switched, with connections always dependent on circuit availability. Packet-switched connection, using the Internet Protocol IP , means that a virtual connection is always available to any other end point in the network.

It will also make it possible to provide new services, such as alternative billing methods pay-per-bit, pay-per-session, flat rate, asymmetric bandwidth, and others. The higher bandwidth of UMTS also promises new services, such as video conferencing and promises to realise the Virtual Home Environment VHE in which a roaming user can have the same services to which the user is accustomed when at home or in the office, through a combination of transparent terrestrial and satellite connections.

Free Access. Summary PDF Request permissions.In early , the Chinese government instructed the dominant cellular carrier, China Mobile , to build commercial trial networks in eight cities, and the two fixed-line carriers, China Telecom and China Netcom , to build one each in two other cities.

This provided the basic access elements as well as circuit switched voice. The core network is then the overall entity that interfaces to external networks including the public phone network and other cellular telecommunications networks.

Today's cellular telephone systems are mainly circuit-switched, with connections always dependent on circuit availability. It provides and manages the air interface fort he overall network.

This is likely primarily for practical reasons, since other 3G formats require the payment of patent fees to a large number of Western patent holders. It handles inter-working between the UMTS packet switched network and external packet switched networks, and can be considered as a very sophisticated router.

Some parts of this band are already used for mobile services in Europe and Asia. However it is essentially the handset in the broadest terminology , although having access to much higher speed data communications, it can be much more versatile, containing many more applications.
