Abstract: A solution is provided that allows prompt notification of new e-mail arrival while minimizing the unnecessary loading of mail server and network resources. It provides a short time delay after arrival of new e-mail when the user needs it most, and minimizes the unnecessary loading of resources when the user does not require immediate notification. This is accomplished by establishing a session with the mail server once a predefined event, such as the sending of new e-mail, has occurred. This session may invoke server-initiated-notification of new-email for a limited period of time.

Abstract: A solution is provided wherein the mobile device selects a multislot class based on the profile of the traffic to be utilized by the mobile device. This may be performed manually by a user, or may be performed automatically where an application or driver software automatically and dynamically determines the best multislot class for the applications being used. This can be accomplished, for example, by looking at the classification of the transport control protocol (TCP) port numbers used, by examining the data sent and received by the network, and/or looking up a profile for the user or device. If the user changes applications or some other event occurs on the mobile device that might cause a change in the profile of the traffic, the mobile device may terminate its current multislot class assignment and re-announce itself, allowing the system to transfer the mobile device to a new multislot class.

Abstract: An application allows the user to monitor the status of groups of wireless modems employed in the field.

The information from the modem units is then displayed to the user at a personal computer.

Abstract: An architecture for performing communications between a remote computer system and a host server over a “connection establishment” type network (i.e., dial-up) is described. The architecture comprises configuring the remote computer system with a Point-to-Point Protocol (PPP) stack. Similarly, an Address Resolution Protocol (ARP) service module and a Dynamic Host Configuration Protocol (DHCP) server are configured on the remote computer system. The PPP stack provides dial-up networking capabilities, while the DHCP server and the ARP service module provide “always connected” type network (i.e., LAN) messaging functionality. The PPP stack, the ARP service module, and the DHCP server are configured as a driver that is installed on the remote computer system. As such, the driver will enable a connection over the “connection establishment” type network that will appear to be an “always connected” type connection to the remote computer system.
