DETAILED DESCRIPTION OF THE INVENTION

FIG. 1illustrates a block diagram of a system2for managing communications through a plurality of devices, in accordance with embodiments of the present invention. System2allows a user to manage a collection of communication devices (e.g., devices8,15,20, and22) using a single user identification (e.g., a user ID) associated with each device. System2may be used to allow the user perform the following functions:

1. Each device identity is associated to or disassociated from a user identity (e.g., a user name) in order to perform the following functions:

A. A user may add/remove devices associated with their user identity (i.e., user ID).B. Computing system4may automatically transmit changes in the set of associated devices to all of the user's devices.C. Computing system4may automatically transmit changes in device availability to all of the user's devices.D. Messages may be transmitted to/from a user ID/device ID pair.E. Messages may be transmitted to all of the user's devices or all of the user's available (i.e., enabled) devices.
2. Update or cancel messages queued on computing system4pending delivery.
3. Save user-specific data on computing system4.
4. Allow a message extension to cause a message sent to other devices to automatically update data stored on computing system4.
5. Set sharing permissions in order to share data with other users.

System2comprises a computing system4(e.g., a server) connected to a plurality of communication devices8,15,20, and22through an interface10. Interface10may comprise any type of interface known to a person of ordinary skill in the art including, inter alia, a local area network, (LAN), a wide area network (WAN), the Internet, etc. Communication devices8,15,20, and22may comprise any type of communication devices known to a person of ordinary skill in the art. For example, inFIG. 1communication device8is a personal computer (PC), communication device15is a cellular telephone, communication device20is a personal digital assistant (PDA), and communication device22is a laptop computer. Computing system4comprises a memory device14. Alternatively, memory device14may be located external to computing system4. Memory device14comprises a software application16, user ID data6, device ID data7, service ID data9, and informational data17. User ID data6, device ID data7, service ID data9, and informational data17may be inputted into computing system4using any of communication devices8,15,20, and22. Device ID data7and service ID data9are associated with or disassociated from user ID data6. Each user has an ID (i.e., an alpha/numeric identifier from user ID data6) that is affiliated with that particular user. Each of communication devices8,15,20, and22comprises an ID (i.e., an alpha/numeric identifier from device ID data7) that is simultaneously unique but affiliated with a particular user (e.g. John Doe/Home Desktop, Joe Doe/Work Laptop, etc).

1. System2maintains a set of communication devices8,15,20, and22for a user (i.e., the user's personal devices). Software application16enables users to indicate changes to their set of communication devices. Additionally, each communication device is able to access information related to the changes. Software application16provides availability information for each of communication devices8,15,20, and22. Additionally, software application16supports sending messages to an explicitly specified subset of a user's devices, all of a user's devices, or all of the user's available devices.
2. System2comprises the ability to delay delivery of messages (i.e., informational data17) to offline (i.e., disabled) communication devices and also supports replacement or cancellation of delayed messages. System2uses a message identifier to indicate which message should be replaced or cancelled.
3. System2provides user specific storage that allows services to cache information on computing system4for the user's communication devices to access at any point in the future. For example, a service that allows users to keep track of recent email contacts across communication devices could cache contact information on computing system4so that other communication devices may access the information. This capability supports sharing a large body of information that could be too big to be exchanged through a single message. System2allows services to directly cache information either all at once or incrementally. Additionally, services can add an extension to messages exchanged with other communication devices to cause computing system4to indirectly update the cache by incorporating some or all of the exchanged information.

Each of communication devices8,15,20, and22comprises a software application (i.e., a client) that runs on each of communication devices8,15,20, and22and communicates with computing system4. Each client (i.e., on each of communication devices8,15,20, and22) is responsible for connecting to and managing communications with computing system4, and it provides an abstraction layer that services running on that device can use to exchange information with other devices. Each client:

1. Receives messages that services want to send to other communication devices.

2. Routes those messages to computing system4.

3. Receives new messages from computing system4for that particular device.

4. Determines which service or services should receive those messages.

5. Routes the messages to those services.

Additionally, each client notifies services of changes in availability for the user's other devices and for any other specified devices that a service expresses interest in. As part of managing communication with computing system4and other devices, the client also notifies services when communication should be suspended due to a lost connection with the computing system4and resumed because of a re-established connection.

The client supports two types of connections with services.

1. The client may directly initiate services itself and communicate with the services via a service object.

2. The client may detect socket connections from services that will be run independently from the client but still exchange messages with computing system4or other communication devices. A client may handle simultaneous communication with multiple services.
The following list illustrates examples of services:
1. A notebooks service that allows a user to keep a set of shared notebooks across personal communication devices.
2. A shared lists service that allows a user to keep a set of lists across personal communication devices and optionally share lists with other users.
3. A “recent shortcuts” service that allows a user to access recent contact information, recently received attachments, and recently used files across any personal communication devices.
4. A multi-device search service that allows a user to initiate a search across personal communication devices from any of those device.
5. A send-a-file service that allows a user to send a file from one personal communication device to any other personal communication device(s).
6. A file synchronization service that allows a user to keep groups of files and/or directories synchronized across multiple personal communication devices.

The following description illustrates the above six examples for using system2for implementing services:

Example 1 illustrates a notebooks service. When a client enables the service, the service requests any current notebooks and their contents for a shared notebooks service ID (i.e., from service ID data9) from computing system4via the client on one of communication devices8,15,20, or22. When the service receives the stored list of notebook names and contents (via the client), it creates a simple graphical user interface (GUI) that displays the list of notebooks. A users may add, delete, or rename notebooks and each action (i.e., add, delete, rename, etc) results in a message transmitted to all available devices (i.e., communication devices that are enabled) for the user detailing the change. The message contains an extension that causes computing system4to store changed data (i.e., informational data17). Users may also edit/add to the notebook contents and each change to a notebook's contents results in a message to all available devices with the new contents. The message contains an extension causing computing system4to store the updated contents.

Example 2 illustrates a shared lists service that provides a user with access to lists of items, which include both a description and a complete/incomplete status, across personal devices and additionally supports sharing with other users. Specifically, a user may choose to share their lists with other users (including allowing other users to edit those lists). When a client enables the service, the service requests any stored data for a shared lists service ID. In addition to adding, renaming, or deleting lists, users may additionally change the user IDs that the list is shared with. When a user makes a change to a list (including its contents), the service sends an update message to all available (i.e., enabled) communication devices for all of the user IDs that the list is shared with. The message contains an extension causing computing system4to store the updated contents.

Example 3 illustrates a “recent shortcuts” service. This service requests a list of recent contact information, recent attachments, and recently used files from a recent shortcuts service ID on computing system4on start-up and displays the results in a GUI. Whenever a user reads or writes a new email message or engages in an instant messaging chat session, the service generates new recent contact information and sends it all of the user's available personal communication devices in a message that includes an extension that causes computing system4to update stored data. The same pattern holds for recent attachments (updated and sent to available personal communication devices whenever the user read an email with an attachment) and recent files (updated and sent to available personal communication devices whenever a device's operating system reports a new recently used file). Whenever the user double-clicks on a listed recently used file or received attachment that is not stored on the current communication device, the service sends a message to the originating device requesting that file.

Example 4 illustrates a multi-device search service. This service presents a simple GUI to the user, who enters any desired search terms. The service then sends a message to all of the user's available personal communication devices with those terms. Each receiving communication device performs a local search for candidate matches and returns that list of candidates to the requesting device. That device presents all the results as a list to the user. The user may double-click on a file in the list to cause the service to send a message to the owning communication device requesting that file.

Example 5 illustrates a file sending service. This service allows the user to choose a file on the local communication device and one or more of personal communication devices to send it to. Issuing this command will transmit the file to all of the specified devices.

Example 6 illustrates a file synchronization service. This service allows users to specify groups of files and/or directories that they want to keep synchronized across one or more of their personal communication devices. The services on the involved devices exchange information about changes to files in the different synchronization groups and when a file is updated on one device the service sends it to the other devices in the group tracking that file.

FIG. 2illustrates a flowchart describing an algorithm used by system2ofFIG. 1for managing communications through a plurality of devices, in accordance with embodiments of the present invention. Each step in the algorithm ofFIG. 2comprises an optional step that may or may not be executed. In step28, a user creates a user ID and a password. The user ID and password is registered with computing apparatus4ofFIG. 1. In step30, the user logs in to system2ofFIG. 1to perform the following process:

1. A client (i.e., a software application on a first communication device) transmits the user ID, password, and device ID (i.e., for the first communication device) to computing system4.

2. If the user ID and password are valid, computing system4performs the following functions:

A. Sets the status for the device ID owned by the user ID to an available status.B. Returns a message to device ID with a roster: a list of user ID's devices and the status (i.e., available or unavailable) for each.C. Transmits a message to each of user ID's other devices indicating that device ID is available.D. Checks for any messages queued up on computing system4that are addressed to user ID/device ID. Computing system4transmits any available queued messages.
3. The client on device ID transmits the roster to each of its connected services.
4. The clients on each of the other receiving devices transmit the availability of device ID to each of their connected services.

In step32, a new communication device is added to system2. The following procedure illustrates the new device addition process:

1. A client (e.g., for the new device) transmits a message from user ID/device ID with a new device ID′ (where device ID′ may be device ID) to computing system4.

2. Computing system4adds the new device ID′ to the list of user ID's devices and sets its status to available (if device ID′ is device ID) or unavailable (if it is not).

3. Computing system4transmits the new roster (list of devices and the status of each) to each of user ID's available devices.

4. Each client on a receiving device transmits the new roster to each of their connected services.

In step33, an existing communication device may be removed from system2.

The following procedure illustrates steps in an existing communication device removal process:

1. A client (e.g., for the device to be removed) sends a message from user ID/device ID with the device ID′ (where device ID′ may be device ID) to remove from computing system4.

2. Computing system4removes device ID′ from a list of user ID's devices.

3. Computing system4transmits a new roster (list of devices and the status of each) to each of user ID's available devices.

4. Each client on each receiving device sends the roster to each of their connected services.

In step34, a service stores data within computing system4. The following procedure illustrates steps in a data storage process:

1. A service transmits a service ID, data ID, and data to a client.

2. The client transmits a message from user ID/device ID with that information to computing system4.

3. Computing system4stores the data in a location indexed by user ID/service ID/data ID.

4. Computing system4returns an acknowledgement to the client.

5. The client sends the acknowledgement to the service.

In step36, a service retrieves data from computing system4. The following procedure illustrates steps in a data retrieval process:

1. A service transmits a service ID and a data ID to a client.

2. The client transmits a message from user ID/device ID with that information to computing system4.

3. Computing system4transmits the data stored at the location indexed by user ID/service ID/data ID to the client.

4. The client sends the data to the service.

In step38, a service transmits a message. The following procedure illustrates steps in a message transmission process:

1. A service transmits an address, service ID, and data to a client.

2. The client transmits a message from user ID/device ID with that information to computing system4.

3. Computing system4performs an action dependent upon on the address:

3a. If the address is user ID′/All Devices (where user ID′ may be user ID), computing system4forwards the message to all of the devices associated with user ID's (optionally excepting device ID if user ID′ is user ID). Computing system4queues up the message for later delivery for devices that are not currently available.3b. If the address is user ID′/All Available Devices (where user ID′ may be user ID), computing system4forwards the message to all of the available devices associated with user ID′ (optionally excepting device ID if user ID′ is user ID).3c. For any other user ID′/device ID′ combination (where user ID′ may be user ID), computing system4forwards the message to the device ID′ associated with user ID′.
4. Each client on a receiving device checks the service ID and sends the message to each service registered to receive messages with that service ID.

A first extension process to the procedure of step38for indirectly updating stored data on computing system4is described as follows:

1. In addition to sending the address, serviceID, and data to the client, the service also sends a data ID.

2. In addition to forwarding the message as appropriate for the supplied address, computing system4also stores the data tagged with the data ID (which may be some or all of the data) in the location indexed by user ID/service ID/data ID.

A second extension process to the procedure of step38for replacing or canceling a queued message is described as follows:

1. In addition to sending the address, service ID, and data to the client, the service also sends a message ID to the client.

2. As before, but including the message ID.

3. As before, but when queuing up the message for delivery to an unavailable device, the server checks for an existing queued message that also has message ID; if it finds one, it either:

(a) replaces the queued message (if the new message includes data).

(b) cancels it (and the new message) if the new message's data field is empty.

In step40, permissions are set for sharing data. The following procedure illustrates steps in a setting permissions process:

1. A service sends a service ID, data ID, some user IDs, a request type, and permissions to the client.

2. The client sends a message from user ID/device ID with that information to the server.

3. If the request type is:

3a. An add request: Computing system4adds the specified permissions (e.g., ‘read’ and/or ‘write’) to all of the specified user IDs.3b. A remove request: Computing system4removes the specified permissions (e.g., ‘read’ and/or ‘write’) from all of the specified user IDs.3c. A set request: Computing system4sets the specified permissions (e.g., ‘read’ and/or ‘write’) for all of the specified user IDs.

In each of cases3a. . .3c, the permissions are set for the data indexed by user ID/service ID/data ID. If data ID is empty (not specified), the permissions apply to all of the data indexed by user ID/service ID (i.e., allowing data sharing at the service ID level).

4. Computing system4returns an acknowledgement to the client.

5. The client forwards the acknowledgement to the service.

In step42, a service requests the permissions for shared data. The following procedure illustrates steps in a requesting permissions process:

1. The service transmits a service ID and data ID to the client.

2. The client transmits a message from user ID/device ID with that information to computing system4.

3. Computing system4transmits the sharing permissions for data indexed by user ID/service ID/data ID to the client. If a data ID is not specified, computing system4transmits the permissions indexed by user ID/service ID.

4. The client transmits the data to the service.

In step44, a service requests shared data stored by another user. The following procedure illustrates steps in a requesting shared stored data process:

1. The service transmits a user ID′, service ID, and data ID to the client.

2. The client transmits a message from user ID/device ID with that information to computing system4.

3. Computing system4checks the sharing permissions for data indexed by user ID′/service ID/data ID. If user ID has permission to read that data, it sends the data to the client.

4. The client transmits the data to the service.

In step46, shared stored data is modified by another user. The following procedure illustrates steps in a modifying shared stored data process:

1. A service transmits a user ID′, service ID, data ID, and data to the client.

2. The client sends a message from user ID/device ID with that information to computing system4.

3. Computing system4checks the sharing permissions for the location indexed by user ID′/service ID/data ID. If user ID has permission to write to that location, computing system4stores the data.

4. Computing system4returns an acknowledgement to the client.

5. The client sends the acknowledgement to the service.

Any of steps32-46may be repeated as many times as necessary.

In step47, the user may log out of computing system4. The log out process performs the following procedure:

1. The client (i.e., the software application on the first communication device) transmits a logout message from user ID/device ID to computing system4.

2. Computing system4transmits a message to each of user ID's other available devices notifying them that device ID is now unavailable.

3. Each client on a receiving device transmits the unavailability of device ID to each of their connected services.

After the user logs out in step47, he/she may either repeat step30in order to log back in or the process terminates in step48.
