Sony Ericsson P802 manual For Internal Use Only

For Internal Use Only	P800 Smartphone
	White Paper, May 2002

The required GPRS server resource is defined by an Access Point Name (APN) rather than a telephone number. Example APNs might be

Corporation.operator.country	Connect to your corporate intranet via a VPN
Internet.operator.country	Connect to internet via the mobile operator’s ISP
Wap.operator.country	Connect to the mobile operator’s WAP service

The Access Server in the GSM/GPRS network will make the connection to the requested resource. Access control and security is performed using standard components such as Radius servers.

Once connected, the user may simply leave the connection in place and access the remote resources as and when required.

The diagram below shows the end-end connection route for a GPRS connection. The P800 and PC ends are the same as before. The mobile operator is enabled to provide direct packet data access to WAP and internet resources. By establishing a suitable Virtual Private Network (VPN) connection to the corporate network, it is possible for the mobile user to access corporate intranet facilities. Your mobile operator will be able to advise you on the available VPN options. Typical methods are IPsec tunnelling over the internet, leased line and frame relay.

The P800 (A) is connected to the Internet Service Provider and may browse the web and check mail. This connection is left open, enabling the mailserver to be polled periodically.

Using the P800 as a modem (B), it may be linked to a laptop PC using either infrared or Bluetooth. A GPRS connection can be made to the corporate network enabling intranet and mail services to be accessed.

The P800 may also be configures to access the corporate network directly using the built-in Browser and Messaging applications.
