A general term referring to technologies which allow a central system (such as the network) to “push” (send) information spontaneously and quickly to a user without any action on the part of the user or the mobile device. A very common “push” technology is email. “Push” emails are directly “pushed” to the mobile device as soon as the email server receives them and it is not necessary for either the user or the device to manually or automatically check for new emails at regular intervals.
