Access Point
An access point is:
- An IP network to which a mobile set can be connected
- A set of settings which are used for that connection
- A particular option in a set of settings in a mobile phone
When a GPRS mobile phone sets up a PDP context, the access point is selected. At this point an Access Point Name (APN) is determined
- Example: aricenttechnologies.mnc012.mcc345.gprs
- Example: Internet
- Example: mywap
- Example: hcl.cisco.ggsn
This access point is then used in a DNS query to a private DNS network. This process (called APN resolution) finally gives the IP address of the GGSN which should serve the access point. At this point a PDP context can be activated.

Famous quotes containing the words access and/or point:
“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
“You should go to picture-galleries and museums of sculpture to be acted upon, and not to express or try to form your own perfectly futile opinion. It makes no difference to you or the world what you may think of any work of art. That is not the question; the point is how it affects you. The picture is the judge of your capacity, not you of its excellence; the world has long ago passed its judgment upon it, and now it is for the work to estimate you.”
—Anna C. Brackett (1836–1911)
