Abstract

A method and apparatus for implementing alerts on a browser running on a portable handheld device is disclosed. The method generates an asynchronous notification action from the server and in response transmits an alert containing a message indicating availability of HTML pages that describe the nature of the alert. The alert is received at a node on a network and translated into the original message. An alert receipt acknowledgment is transmitted to the server. Access to the alert HTML page is provided through a URL containing the appropriate query strings necessary to present the appropriate HTML page. The invention also discloses a wireless local area network (WLAN) adapter associated with a wireless network that receives paging signals from a server on the network and returns an acknowledgment signal back to the server. The invention also discloses a client/server based method of delivering messages initiated by a client. After a connection is established between a client and server, the client requests a message from the server. In response, the server retrieves and returns the message back to the client.

Claims

1-7. -7. (canceled)

8. A wireless mobile network unit, comprising:

an input device for receiving data input from a user;

a display device supporting HTML functionality allowing the user to examine data;

a processor programmed to support the user of asynchronous application alerts;

a transmission device for receiving the alerts and transmitting an alert receipt acknowledgment; and

a memory containing instructions to receive a paging signal.

9. The network unit of claim 8 further comprising:

a processor which supports user datagram protocol frames and processes protocol data units consisting of command elements constructed as ASCII, comma delimited, strings.

10. The network unit of claim 8 further comprising:

a transmission device which transmits data via user datagram protocol services.
