Positioning

The basic cost-efficient positioning method available in 2G networks relies on measuring round-trip time. In 2G it is called Cell-ID + TA (Timing in Advance).

Time difference measurement, involving several base stations, can be used to obtain a more accurate position.

GPRS

Positioning methods are already used to support location-based information services such as ©YellowPages, restaurant guides, traffic information, directions and friend finder applications. Typically WAP, SMS or voice has been used as delivery mechanisms. Java and MMS will add new possibilities to deliver attractive location- based applications.

The introduction of GPRS was a big step in the evolution of the GSM networks for enhancing the capabilities of data communication. Data traffic has increased (over both wired and wireless networks), with the growth in demand for Internet access and services paralleling that of mobile communications.

We can now see that the demand for fast Internet access is the key driver for coming generations of wireless multimedia and entertainment services.

GPRS is able to take advantage of the global coverage of existing GSM networks. Applications developed for GPRS have been deployed on a large scale and have thus reaped the associated benefits.

With a GPRS subscription, transmission capacity is only used when data “packets” are sent or received via a connection.

Instead of occupying an entire voice channel for the duration of a data session, the K700 sends and receives data in small packets, as needed, much like IP on the Internet. Thanks to this, the phone appears to be always online, using transmission capacity only when data is sent or received. The phone is compatible with GPRS R97.

The phone uses up to four time slots for receiving data, and two slots for transmitting.

Phone identity information and characteristics of the connection are described in the PDP (Packet Data Protocol) context. This information is stored both in the phone and in the mobile network, so that each phone is identified and “visible” to the system.

Using GPRS has many advantages, for example:

Cost efficient

Use transmission capacity only when needed, thus reducing costs.

WAP over GPRS

Access the Internet via WAP at high speed.

E-mail over GPRS

Remain connected to an e-mail system while reading and preparing messages, (which are then sent at high speed).

Data communication

Transfer data and access the Internet or an intranet with a PC, PDA or handheld device connected via Bluetooth wireless technology, infrared or cable.

Provide settings

Receive GPRS configuration settings from the provider OTA (over the air), making manual con- figuration unnecessary.

User-controlled settings

Take advantage of full user control in the data connections menu, establishing multiple descriptions and accessing advanced settings for GPRS.
