Although the processor 14s executes the software that runs these devices, it is common to state that the computer 12s runs these devices.
  • the sender may also have a wireless pager 28s and a voice-mail server 30s, which are also connected to the path 18.

  • the computers and message devices are labeled as sending or receiving devices for description purposes, it is understood that these labels are arbitrary such that the sending computer and message devices can be used to receive messages and the receiving computer and message devices can be used to send messages.
  • the system 10 may also include a file server 32, which is connected to the path 18 and which can assist with the transfer of messages between the sender's messaging devices and the recipient's messaging devices.
  • the server 32 may be a server of an internet service provider (ISP), which facilitates the transfer of messages between ISP account holders and between an account holder and a non-account holder.
  • ISP internet service provider
  • the server 32 may be a paging company's server that transfers messages between the wireless pagers 28s and 28r.
  • the network 10 typically allows two topologies for transferring messages from one device to another: the point-to-point (PTP) topology, and the star topology.
  • PTP point-to-point
  • a message is routed directly between the sending and receiving devices.
  • the desktop pager 20s sends a message directly to the desktop pager 20r via the computer 12s, the path 18. and the computer 12r.
  • the server 32 may open this direct path between the pagers 20s and 20r.
  • the message is routed through an intermediate node or device such as the server 32.
  • the pager 28s sends a message intended for the pager 28r to the server 32, which may be the paging company's server.
  • the server 32 then processes the message and sends it to the pager 28r. This may occur for security or other reasons. Therefore, because the PTP topology eliminates the overhead of having the server receive and send the message, it is often faster and ties up fewer network resources than the star topology.
  • the server 32 may be programmed to route all messages with a star topology to prevent messaging failure. This may create an unnecessary bottleneck at the server 32, thus significantly increasing access times and aggravation for users of the server 32.
  • the server software will have to be modified to allow this.
  • the server 32 can be used in both network environments, then the server manufacturer will have to develop and offer two respective software packages, one for PTP and another for star.
  • the customer will have to install new software if the network environment changes, or if he wishes to install the server 32 in another network 10 having a different environment.
  • a recipient is often unable to retrieve messages from some of his message devices for extended periods of time, and if a message device is unavailable to receive a message, the message may be lost.
  • the sender sends an e-mail message from his e-mail client 24s to the recipient's e-mail server 26r. If the recipient is out of town and has no access to the server 26r other than through the e-mail client 24r, then he must wait until he returns before he learns of and can read the sender's e-mail message. Alternatively, if the sender sends a desktop page from his pager 20s and the recipient's desktop pager 20r is not running, then the message has nowhere to go and may be lost.
  • a message transfer may be unsuccessful if the sending device is of a different type than the receiving device. For example, if the recipient's e-mail client 24r is Microsoft Outlook, it may be unable to read an e-mail message from e-mail clients other than those sold by Microsoft.
  • the server 32 may use polling to allow a sender to determine if an intended recipient's message device is available to receive a message. For example, if the sender wants to send a desktop page, he may first want to determine if the intended recipient's computer is logged onto the server 32, and thus if the recipient is "online" and able to receive the page. To make this determination, the sender requests, via his computer 12s, the server 32 to poll all of the computers that are logged onto the server 32 and to notify the sender if one of these computers is the recipient's computer 12r.
  • a computer communicates with a server.
  • the computer includes a storage device for storing client software that includes access information for first and second messaging devices.
  • the computer also includes a processor that runs the client, provides the access information to the server, generates a message routing preference that causes the server to route a message sent to the first receiving device to the second receiving device, and provides the message routing preference to the server.
  • Such a computer can instruct a server to route a message intended for one of a recipient's message devices to another of the recipient's message devices. For example, suppose the recipient is going on a trip and will not have access to his e-mail account while away. Through his computer, he can instruct the server to route all e-mail messages received while he is away to his wireless pager so that he can view these messages before returning from his trip.

  • the server 64r routes messages between the message devices ofthe network 63r in a similar manner.
  • the server 42 allows a sending device in the network 62s to send a message to a receiving device in the network 62r and routes the message according to the recipient's routing rules.
  • the firewalls 63s and 63r prevent the server 42 from implementing a PTP topology for such a message. But because the server 42 can automatically select the proper topology, the same server 42 that is used in the network 40 of Figure 2 can also be used in the network 60. That is, neither the server hardware nor server software need be modified, so manufacturing and installation expenses are reduced compared to prior-art communication servers.
  • Figure 4 is a flow chart that details one embodiment of the general topology selection and message routing procedure used by the networks 40 and 60 of Figures 2 and 3, respectively. For clarity, reference will be made to the elements of Figure 2 unless otherwise specified.
  • the sending device for example the desktop pager 20s, initiates the sending of a message to a receiving device by sending a conventional message-initiation header to and requesting the IP address and dynamic encryption key of the receiving device (or of the computer, such as the computer 12s, running the device) from the routing server 42 via the path 18.
  • the pager 20s typically sends this information to the path 18 via the server 64s.
  • the message-initiation header typically includes information such as the identities of the sender and recipient and the length and priority of the message.
  • the server 42 determines the identities of the sending and intended receiving devices from the format of the message header. For example, a header from the desktop pager 20s often has a different number of bytes or is otherwise different than a header from the web browser 22s.
  • the server 42 examines the message-initiation header and, based on the header, the network environment, and the recipient's routing rules, determines the appropriate receiving device and whether or not PTP communication between the sending and receiving devices is possible.
  • the sender desires to send a message from his desktop pager 20s to the recipient's desktop pager 20r. Furthermore, suppose that the recipient's routing rules indicate that the desktop pager 20r is to receive this message. If the server 42 determines that there are no firewalls or other network environment conditions that prevent a PTP topology, it implements a PTP topology.
  • the server 42 determines that a star topology is appropriate so that the server 42 can receive and reformat the message from the e-mail client 24s and then send the reformatted message to the desktop pager 20r.
  • desktop pagers such as the desktop pager 20r often limit the size of a received message to 100-200 bytes. Therefore, if the message from the e-mail client 24s is longer than this, the server 42 will decide on a star topology so that it can receive and truncate the message before sending it to the desktop pager 20r.
  • the server 42 may implement the star topology. For example, suppose the sender wishes to send an e-mail message having a one-megabyte attachment to ten recipients, and that all of the recipients' routing rules indicate that the server 42 is to route such an e-mail message to their respective e-mail servers 26r. In one embodiment, because of the file length and the relatively large number of recipients, the server 42 determines that multicasting is more efficient than setting up direct PTP paths between the sender's e-mail server 26s and the respective e-mail servers 26r.
  • the server 42 implements a star topology by instructing the e-mail server 26s to send the message to the server 42 only once, and then sending the received message to each of the e-mail servers 26r of the respective recipients.
  • the server 42 may forward the message to a conventional multicasting server (not shown), which sends the message to each ofthe e-mail servers 26r.
  • the server 42 may allow the sending device, such as the desktop pager 20s, to first try to send a message with a PTP topology, and if this attempt fails, the server 42 instructs the sending device to retry with a star topology.
  • the server 42 may implement variations ofthe star topology in the network 60 if one or both of the firewalls 63s and 63r prevent the server 42 from opening a PTP path between a message device of the network 62s and a message dev ice of the network 62r.
  • the server 42 after determining that it cannot implement a PTP topology, the server 42 first tries to implement a version of the star topology in which the server 42 bypasses the servers 64s and 64r and communicates directly with the sending and receiving devices. This is significantly faster and causes less traffic on the networks 62s and 62r than if the message were routed through the servers 64s and 64r.
  • the server 42 receives the message from the pager 20s and sends it to the pager 20r in a manner similar to that described above with respect to a star topology in the network 40 of Figure 2. If the server 42 cannot implement this version of the star topology, then, as a last resort, the server 42 routes the message through one or both of the servers 64s and 64r.
  • the server 42 sends the IP address and the dynamic encryption key of the receiving device specified by the routing preferences (or of the computer 12r if it is running the receiving device) to the sending device.
  • the sending device sends the message directly to the receiving device - thus bypassing the server 42, and with respect to the network 60 of Figure 3, bypassing the servers 64s and 64r - and, after it sends the message, conventionally closes the direct PTP communication path over which the sending device sent the message.
  • the server 42 if the server 42 cannot implement a PTP topology, the server 42 implements a star topology. Specifically, the server 42 opens a communication path between itself and the sending device and notifies the receiving device specified by the recipient's routing rules of the incoming data stream that forms the message. For example, as discussed above, if the e-mail client 24s is the sending device and the desktop pager 20r is the receiving device, then the server 42 opens a path between the e-mail client 24s and itself via the e-mail server 26s, and notifies the desktop pager 20r that a message is forthcoming.
  • step 81 the sending device transfers the message to the server 42.
  • the server 42 reformats the message if necessary and then sends the message to the specified receiving device. For example, if the e-mail client 24s is the sending device and uses a first message format and desktop pager 20r is the receiving device and uses a second message format, the server 42 converts the message from the e-mail client 24s into the second format, and then transfers the reformatted message to the desktop pager 20r.
  • step 85 when the sending device finishes sending the message, it notifies the routing server 42, which conventionally closes the communication path between itself and the sending device,
  • step 87 the server 42 conventionally closes the communication path between itself and the receiving device.
  • the servers 42 of the networks 40 and 60 of Figures 2 and 3, respectively can facilitate more efficient communication between message-sending and message- receiving devices by automatically selecting the best network communication topology. Also, the servers 42 allow a recipient to redirect a message from one receiving device to another receiving device, and allow a message device of one type to communicate with a message device of another type.
  • Figures 5-8 disclose embodiments of techniques that allow a sender to send a message to the recipient such that the server 42 can route the message according to the recipient's routing preferences.
  • Figures 5-8 are discussed in conjunction with the network 40 of Figure 2, it being understood that the discussion is also applicable to the network 60 of Figure 3 unless otherwise noted.
  • Figure 5 is a computer screen 90 that allows a sender who is a registered user of the routing server 42 to send messages to a recipient who is also a registered user of the server 42.
  • the sender uses the routing client 48s to create one or more groups of recipients, and adds the recipient to one of these groups. For example, a sender may have a group for work colleagues and another group for personal friends.
  • the client 48r for each designated recipient prompts the respective recipient for messaging information, receives the information from the recipient, and makes this information available to the sender via the server 42. Based on this information, the routing client 48s generates the screen 90 on the sender's computer 12s.
  • the screen 90 includes a list field 92, which includes a list of messaging devices that the recipient has made available to receive messages from the sender.
  • the routing client 48 s is run in a Microsoft Windows® environment so that the sender can select the desired messaging device by pointing and clicking with a mouse.

Furthermore, suppose that the recipient's routing preferences instruct the server 42 to route desktop pages to the e-mail server 26r if the computer 12r is off line. Thus, the server 42 informs the sender that any page he sends will be routed to the recipient's e-mail server 26r and asks the sender if he still wants to send the page or if he wants to cancel and wait until later. If the sender decides to go ahead and send the page, the server 42 will route the page to the e-mail server 26r.

If there is a rerouting condition, however, then referring to step 144, the client determines if the condition is met.

Thus, if the recipient does not pick up the page within the allotted time, then the client 48r causes the server 42 to reroute the page to the e-mail server 26r.
  • the client 48r monitors the receiving device to determine if the condition is met. This embodiment is useful when the receiving device, for example the desktop pager 20r, is part of the client 48r. In another embodiment, the receiving device notifies the client when the condition has been met.

In the embodiment shown, the recipient enters the preferred device or devices, here the e-mail server 26r, in a field 149. Thus, if the recipient is out of town and is not running his computer 12r, then the server 42 will forward all desktop pages to his e-mail server 26r.

Abstract

Selon l'invention, un ordinateur exploite un logiciel client qui apprend les identités des dispositifs de communication d'un utilisateur, développe des préférences pour acheminer des messages d'entrée envoyés à ces dispositifs et fournit ces identités et préférences de routage à un serveur de routage. L'utilisateur peut fournir les identités du dispositif et les préférences de routage au client via un dispositif d'entrée tel qu'un clavier. Le client peut également acquérir les identités du dispositif en recherchant les dispositifs de communication qui sont installés sur l'ordinateur, et peut développer les préférences de routage en fonction des schémas de gestion des messages de l'utilisateur. Ainsi, le client peut développer et fournir au serveur une préférence de routage qui amène le serveur à acheminer un message envoyé à un premier dispositif de communication vers un deuxième dispositif de communication.
