Push services
These are useful for sending updated WAP site contents or WAP links to mobile users. Examples of services that can be implemented using push services:

Service Loading (SL)
This means that the WAP site content is immedi- ately loaded and executed on the client, or alterna- tively is loaded and stored in the cache for later use. In both cases, the SL is loaded without any user intervention.
When a service indication is received in the Z300, it is presented to the user in one of the following ways:

•Low
