Abstract: Redirecting a notification to a wireless user device includes registering for notification of incoming messages for an account on a message server, the incoming messages being directed to an account on the message server. The redirecting also includes receiving at least one notification and redirecting the at least one notification through a firewall to a wireless user device associated with the account. The remote message server is in communication with a network protected by the firewall. According to one aspect, a cradle is configured to perform the redirection. According to another aspect, the cradle is associated with a remote desktop computer in communication with the network.

Abstract: The present invention provides a solution in which a script containing general security parameters and access policies in a file is placed on an appropriate internal server. The location of the script may then be stored on an external server. When an end-user within the organization decides to purchase a wireless network device, he may attach it to his existing computer. The computer then may retrieve the security file location from the external server, retrieve the security file from the internal server using the security file location, and program the security file into the wireless device.

Abstract: A solution is provided wherein a VPN session may be suspended without termination. When a user wishes to connect to a host outside of the VPN, the device does not abandon the secure connection. Instead, it stores all the necessary network parameters associated with the secure VPN connections for later recall. When the user later wishes to connect to the VPN again, the device may then simply recall the necessary network parameters associated with the prior secure VPN connection, and begin data transfer with the VPN.

Abstract: A data communications network may be browsed using one or more tokens by receiving an input keyword string from a user, determining whether there is a match between the input keyword string and a database of keyword strings, determining a category of the keyword string, rendering to the user at least one service identifier associated with the category, receiving a user-selected service identifier in response to the rendering, substituting at least one variable in a resource locator template associated with the service with a string based at least in part on the keyword string entered by the user and launching the resource locator. According to one aspect, a special rendering of a hyperlink corresponding to the resource locator is used to indicate private data will be disclosed upon launching the resource locator.

Abstract: An authorization-update process for use in a user-operated device re-authorizes an operating session after a rapid idle timeout using the authorization-update process, which has fewer steps than a normal authorization process. The re-authorization process can require only a single entry or input event by the user in response to a prompt by the device to re-authorize the user and continue to the operating session. Thus, the authorization-update process is significantly faster than re-authorization in the conventional manner. In one embodiment, the prompt includes a display of several characters. The user selects a predetermined character to re-authenticate the user, thereby continuing the operating session from the same point at which the idle timeout occurred. In a further aspect, the user has a predetermined time period to select the correct character to continue the operation session.

Abstract: A solution is provided wherein standard mail servers may be used to assist the synchronization of application data across multiple devices. This allows the synchronization of application data without requiring contemporaneous operation of the synchronization partner devices. This may be accomplished by generating a record for each change to a database on a first device. Upon synchronization of the first device with the mail server, the changes since the last synchronization may be uploaded to the mail server and stored in a mailbox for a user associated with the device. If a second device associated with the user then attempts to synchronize with the mail server, the records may be downloaded and the corresponding changes implemented in the database on the second device.

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: New e-mail may be identified in an efficient manner in order to speed polling times by utilizing the unique identifiers assigned to e-mails. A unique identifier for the most recently received mail for the mail client or the predicted value for such may be compared with the last unique identifier to be assigned by the mail server. If the identifiers are equal, then no new messages have been received and the mail client need not download any headers, which saves a significant amount of bandwidth. When the identifiers are not equal, the mail client need only download the new headers, which also saves bandwidth.

Abstract: The present invention provides a solution wherein the underlying data network characteristics are detected by a mail client, which may then select the most efficient and effective use of the underlying data channel. In an embodiment of the present invention, the use of the data channel may be made more efficient by selecting a synchronization strategy based on the underlying data network characteristics. For example, in a high-bandwidth data network, full synchronization may be used, but in a low-bandwidth network, only partial and/or select synchronization may be used. This prevents the email user from having to reconfigure the mail client to ensure the most efficient synchronization process when the portable device is attached to a different network. This also reduces the possibility of inefficient usage of low-bandwidth data networks, thus improving network capacity and scalability.
