BACKGROUND OF THE INVENTION Field of Invention

The present invention relates generally to the field of network communications.

More specifically, the present invention is related to a system and method for call routing and selective disclosure of available modes of communication. Discussion of Prior Art

Networks, such as wide area networks and the Internet, allow users to communicate multimedia information between various computer-based devices. Prior art systems provide various ways for communicating voice and video over the Internet. One drawback associated with such prior art systems is the inability of users to control such communication devices, over a network, to define personalized routing of information.

State of the art systems enable users to utilize (in conjunction with a network such as the Internet) a number of communication devices integrated with conventional telephony systems. For example, Internet phones, cellular phones, video conferencing equipment are implemented to work with conventional wide area network (WAN) systems. But, in a scenario wherein one or more communication devices (representative of one or more communication systems or mediums) are linked to a WAN, such systems are not able to dynamically direct an incoming communication to a communication device of choice that is linked to the WAN.

The following references describe prior art in the field of network communications, but none of them provide for an interface wherein subscribers are able to dynamically reveal their communication availability (i.e., text, voice, not available, home, at work, on vacation, etc.) in varying forms to one or more individuals (or organizations). U.S. Patent Numbers 5,375,161 and 5,432,845 provide for a telephone control

redirection or routing system. These patents allow for the rerouting of incoming calls to one

or more pre-determined locations.

U.S. Patent No. 5,471,519 provides for a communications monitoring and control system wherein, upon receipt of communication, the system determines the location of the

called party from a changeable list including locations selectively provided by the called

party. The communication can be accepted, rejected or monitored by the called party. Furthermore, the called party can discontinue monitoring or connect to the communication

at any time during the communication.

U.S. Patent No. 5,579,375 provides for a call transfer within cellular

communications system wherein calls that cannot be completed are redirected with an intelligent call forwarding list. The patent's method includes analyzing a request along with a priority list to determine the optimum number (from the list) for transfer and completion of the call.

U.S. Patent No. 5,600,704 provides for a system and method for prioritized routing of telephone calls to a subscriber wherein the telephone numbers of the several telephones associated with the subscriber are initially assigned relative priorities such that the

telephones are sequentially alerted according to the prioritized routing lists of telephone Furthermore, it should be noted that the prior art systems fail to provide for an

interface that dynamically indicates, either aurally or visually, the availability of other users

based on their desire to selectively reveal their availability, on the current status of their communication devices, on their current forwarding rules and on the requestor's identity.

Additionally, in the prior art systems described above, users are not able to customize their routing flow based on who is initiating the communication. These and other improvements

to the prior art will be described hereafter in the detailed description.

Whatever the precise merits, features and advantages of the above mentioned prior

art systems and references, none of them achieve or fulfills the purposes of the present

invention.

SUMMARY OF THE INVENTION The present invention provides for a system and method for a subscriber to

dynamically reveal their availability status for communicating with one or more entities or grouped entities. A subscriber creates one or more routing policies for specific entities or

groups (that help determine the order of termination of communication devices (e.g., home, office, cellular, unavailable, etc.) as well as the type of available communication medium

(i.e., text, voice, etc.). The availability status is a function of the current policy of the subscriber, which contains their routing policies, general and security preferences (privacy), combination of these items will create a selective revealing of the subscribers availability

based on a match to a correspondingly identified requestor.

Based on the present invention, subscribers are able to maintain one or more policies (corresponding to one or more requestors or groups of requestors) that help selectively

reveal the availability mode of a subscriber based on the identity of the requestor. For

example, if subscribers L and M initiate a communication requesting the availability of

subscriber N, and subscriber N utilizes two communication devices, device 1 and device 2, to receive such communications, the system of the present invention allows subscriber N to

maintain two separate policies, one each for subscribers L and M, regarding how the

incoming communication (regarding availability) is to be handled. In other words, the system of the present invention allows subscriber N to selectively reveal the availability (to

subscribers L and/or M) for communication (via device 1 and/or device 2) based on subscriber-based pre-defined customizable policies. For example, if device 1 in the

described example is a home phone and device 2 is a cellular phone, the system of the

present invention allows subscriber N to create:

• A first policy to reveal availability in the home phone and cellular phone

if subscriber L is initiating the availability request, and

• A second policy to reveal availability in home phone only if subscriber M

is initiating the availability request.

The present invention further provides for both a visual (e.g., GUI) and aural (e.g., a contact list of subscribers is modified as the availability status of those listed changes

(including changes in policy by the contacts towards the possessor of the contact list).

Furthermore, the interface visually modifies graphical images (such as icons) to indicate the

various availability modes associated with subscribers in the contact list (passive) as well as requests about subscribers not in the contact list (active).

hi an exemplary IVR embodiment, a request for status availability is received by the

system through, e.g. PSTN, cellular, etc., and the subscriber status revealed back through the originating telephone connection. Furthermore, the present invention used in conjunction

with a network, such as the Internet, allows subscribers to receive calls on any desired

device (e.g., IP client, PSTN, Mobile) using the routing policy that lists the communication devices in the desired order of termination.

In another extended embodiment, the queries for availability of subscribers are

performed via an electronic message such as e-mail, hi this scenario, the availability mode

of the subscriber who is to be contacted is returned via an electronic message to the requestor.

hi yet another embodiment, service providers are able to modify the active

subscriber policies of behalf of their subscribers in accordance with predetermined communication preferences (automatic or defined by subscribers). Figure 1 illustrates the various parameters that affect a query for determining the

availability mode.

Figure 2 illustrates the three indicators associated with the availability mode.

Figure 3 illustrates a scenario wherein users are able to access a server hosting the

present invention, over a network, via a computer-based device. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS

While this invention is illustrated and described in a preferred embodiment, the

invention may be produced in many different configurations, forms and materials. There is

depicted in the drawings, and will herein be described in detail, a preferred embodiment of

the invention, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and the associated functional specifications for its construction and is not intended to limit the invention to the

embodiment illustrated. Those skilled in the art will envision many other possible variations within the scope of the present invention. It should be noted that the term "user" is used interchangeably throughout the

specification with "subscriber" and in addition each user/subscriber can be defined as a "recipient" or "requestor" depending on whether one is receiving a communication request

for determining availability (or receiving an update of a contact list from a system server) or

whether one is initiating a communication for determining availability.

The method of the present invention may be implemented, for example, via

availability status determining software such as one or more availability mode manager

agents (AMMA) as described in co-pending US application, serial number 0#/#######, hereby incorporated by reference. Each AMMA determines an availability mode for a

specific subscriber based on a current policy of the subscriber (their routing policy + privacy preferences) and the presence of the subscriber's devices. According to the present invention, whenever a query for an 'availability status' (active) or an server initiated update

(passive) of subscriber's availability is made, a subscriber's availability function (or agent) is activated. The specifics of the agent are not necessary for a complete understanding of

the present invention; other functionally equivalent methods of intelligently filtering the availability data can be substituted therefore without departing from the scope of the present

invention. The specific weighting given to the policy and presence information as well as

the specific algorithms used to evaluate this information should not be restrictive to the present invention's novel dynamic revealing of an availability status indicator. be found in co-pending US patent application, serial number 08/780,739, hereby

incorporated by reference.

Figure 1 illustrates an availability status functional hierarchy, the hierarchy

comprising determining for each request for availability status of a subscriber (active) or

server initiated (passive) updating of status availability changes of subscribers:

a) The current policy of each subscriber 102. The current policy consisting of a

combination of the current routing policy 106 of the subscriber and the

subscriber's preferences (e.g., security or other privacy preferences). The routing policy defines how an incoming communication (such as a call or text messages

or video conference) is to be routed. Examples of subscriber preferences 108,

include but are not limited to: 'don't show my current routing policy to people

that are not in my contact list', 'show mom that I'm available only for text no

matter what my real availability is', T want only video conferencing with my kids' etc.

b) The presence of each communication device (e.g., office phone, cell phone,

instant messaging, e-mail, etc.) participating in the current routing policy 104.

It should however be noted that, although the routing policy has the greatest effect on the availability mode, it is not a one-to-one correspondence as other parameters are present invention is a function of the routing policy, the devices' presence and preferences of a subscriber.

An availability indicator is what is shown/played to a subscriber requesting the 'status' (i.e., the availability status) of a subscriber. It should be noted that a variety of interfaces (by which one queries the availability mode) can be used in conjunction with the invention. For example, subscribers are able to query the availability mode of another subscriber via a browser based GUI, a cellular phone interface, wherein the cellular phone is wireless application protocol (WAP) enabled, or using a regular phone (PSTN) to query the availability of the subscribers using IVR.

Similarly, a dual tone multi-frequency (DTMF) telephone system can be used to query the availability mode of another subscriber. For example, one can call and inquire about the availability mode of a subscriber and receive the response in the same phone using an interactive voice response (IVR) feature.

In one embodiment, subscribers with electronic messaging access are able to send a message (such as an email) querying the availability mode of another subscriber. In such a scenario, the 'availability mode' of the queried subscriber is also returned via an electronic message such as email. availability status information. In this scenario, icons representative of the availability mode

of the queried subscriber are sent and displayed in requestor's GUT.

Thus, as illustrated in Figure 2, the availability mode comprises one or more of three different indicators (visual or aural):

1) Media types the subscriber can be reached by 202.

2) Current routing policy name of the subscriber 204.

3) An indicator for specifying the subscriber's availability. For example, in the

case of a GUI, an icon indicating the subscriber's availability 206 is

displayed via an interface. It may indicate 'in a meeting', 'busy', 'please don't call', etc. It should be noted that the number of icons is either equal to

or be less than the number of routing policies.

The 'presence' of a device is an indicator about the device current 'status'. Different

devices have different statuses associated with them. For example, in a telephone (such as a

network phone or Internet phone), 'presences' are any of the following: online, offline,

away, or busy. Additionally, regular phones also include the 'presence', 'unknown'.

Cellular phones, on the other hand include the following 'presences': connected, silent, or busy.

In one embodiment, the present invention maps each of the device's preferences to mobile device) means 'offline', but the subscriber is able to decide what 'silent' means and

thus, by consequence, how it affects the availability mode.

The preferences of a subscriber also affect the availability mode. For example:

• Subscribers are able to show different availability modes (of media types) for different contacts/non-contacts. Thus, subscribers are able to discriminate

and control what is shown to different groups.

• Subscribers are able to show the current routing policy name.

• Subscribers are able to change the interpretations of presence. For example,

instead of saying that 'silent' on cellular means 'offline', uses are able to define it as 'away').

Figure 3 illustrates a scenario wherein subscribers are able to access a server hosting

the present invention's availability status determining software over a network via a variety

of communication devices. For example, a subscriber is able to access server 300 over

network 302 via any of the following devices: personal computers 304, external server 306,

mobile computers 308, personal digital assistant (PDA) 310, mobile phones 312, telephones

314, or pagers 316. It should however be noted that although only certain devices are

illustrated as input/output devices in Figure 3, one skilled in the art can envision substituting

other communication devices in place of the devices illustrated. Network 302, described in the Figure 3, and as used in this specification is any of, but not limited to, the following Figure 4 illustrates a preferred embodiment wherein the present invention is used in

conjunction with Internet 402. Furthermore, the network comprises a plurality of subscribers that have access to conventional gateways such as telephone gateways. Two

users (subscriber A and subscriber B) are used in the examples to follow and should be

noted that this scenario is used for illustration purposes only. Thus, one skilled in the art

can extend the same description for any number of subscribers or groups of subscribers without departing from the scope of the invention. In addition, the example has identified an active mode (request) for revealing the availability status, however, equally applicable in

the preferred embodiment, the server will automatically push updates of subscriber

availability to all contact lists containing a specific subscriber.

As mentioned above, each subscriber employs a plurality of communication devices,

communication device 1 (408 (A), 412 (B)) through communication device n (410 (A) and

414 (B)), to communicate with other subscribers over the Internet. As in the illustrated example, subscriber A utilizes communication devices such as a home telephone or office

telephone, wherein both phones are connected to the Internet via a gateway, such as

telephony gateway 416. Furthermore, subscriber A is able to employ one or more clients

(418-420) to communicate directly with server 422 and with other subscribers via a

network, such as the Internet. For example, subscriber A is able to utilize a client such as a

computer to connect to the Internet. Furthermore, subscriber A's computer is equipped with Likewise, subscriber B employs communication devices (412-414) such as a home telephone and cellular phone, wherein the communication devices are connected to a network such as the Internet via a gateway, such as telephone gateway 424. In case of a cellular phone, it is connected to the cellular telephone company via a cellular network and from there to the Internet via the telephony gateway. Similar to subscriber A, subscriber B also has direct access to server 422 via the Internet through one or more clients (426 and 428). Just as with subscriber A, subscriber B is able to employ an application enabling audio and video conferencing, to send and receive instant messaging, to see the availability modes of their contacts and their current routing policy.

It should be noted that although specific examples of network gateways, such as telephone gateways, are used in illustrating the present invention, one skilled in the art can extend the present invention to encompass other means for accessing a network. For example, subscribers are able to access server 422 via a remote computer client (connected to the Internet) 424 that includes a browser such as Microsoft's Internet Explorer^® or Netscape^®. Subscriber A's webpage, in one embodiment, contains an indication regarding availability of other subscribers.

It should be further be noted that although in the preferred embodiment the server is accessed by one or more subscribers, an extended embodiment is envisioned wherein users Continuing with the' example, using the present invention, subscriber A configures

home telephone and office telephone numbers. Next, automatic routing policies are either

picked (from pre-defined policies) or created anew. Given below is an example for a routing policy for subscriber A. i this example, subscriber A utilizes the various available

policies. As mentioned earlier, there is also a possibility of customizing the routing policies

to meet individual needs.

Subscriber A's Routing Policies:

Policies Available: Out of reach (don't accept audio and don't accept text).

Text only (accepts only text).

Network Phone (such as an Internet Phone) routing order: PC

Client first, then Office phone, then Home phone. Home (only home phone).

Office (only office phone).

• Subscriber A's current chosen policy is an Internet phone.

• Both client 1 and client n are online.

• Subscriber A has Subscriber B in the contact list.

• Subscriber A's preferences say: 'Show my availability mode to people in

contact list, but not to people not in contact list.' from pre-defined policies or created anew. Given below is an example for a routing policy

for subscriber B. In this example, subscriber B customizes the routing policies to meet

individual needs.

Subscriber B's Routing Policies:

Policies Available: Out of reach (don't accept audio and don't accept text).

h a meeting (accept text only).

Network phone (such as an Internet phone): Routing order is

PC client first then mobile phone).

Mobile (mobile phone).

Home (home phone, mobile phone)

• Subscriber B ' s current chosen policy is 'in a meeting. '

• Client 1 is online.

• Subscriber B has Subscriber A in the contact list.

As mentioned earlier, a request (active mode) for the availability mode of a

subscriber can be originated from any connected device illustrated in Figure 3. A simple

scenario would be: a request to know the availability mode of subscriber A is directed to

server 422 from one of subscriber B's devices. Knowing the current chosen routing policy

and privacy preferences of subscriber A, and being aware of the presence of each of

subscriber A's devices, server 422 determines subscriber A's availability mode for policy and an indication of their availability status. The format of the response is any of, but

not limited to, the following: audio input/output such as IVR, text or graphical.

In the above example, using the current settings, subscriber B will see subscriber A

as available for online calls and for instant messaging. Furthermore, the current routing

policy name of subscriber A (Network Phone) is visible to subscriber B. If, for example, subscriber A now deletes subscriber B from the contact list, subscriber B will stop from seeing subscriber A as available for call or for text (due to his preferences), although

subscriber B's routing policy wasn't changed.

According to the present invention, a determination of the availability mode of

subscriber A is directed to an agent of the availability status software hosted by server 422

(e.g., Availability Mode Manager Agent (AMMA)). The agent receives this request from a device employed by one of the subscriber's contacts (or from an intermediate device to

which one of the subscriber's contacts is connected, or from an intermediate device to which one of the subscriber's contacts is connected, or from any other computer-based device). A non-limiting example for a contact's device is a phone, or a mobile phone with WAP capabilities or a network phone (such as a black phone) connected to the Internet via a

telephone gateway. The agent determines subscriber's availability mode for specific

subscriber's contacts based on the current chosen policy of the subscriber, the privacy preferences of the subscriber, and the presence of each of the subscriber's devices. It should be noted that while the present invention is described with respect to a

single subscriber connected to an agent of the availability status software, one skilled in the

art can extend it to be applicable to a plurality of subscribers connected to a single agent, to

multiple agents, or to a service provider modifying one or more agents on behalf of its subscribers in accordance with predetermined communication receipt preferences

(automatic or defined by subscriber.

Figure 5 illustrates the method associated with the present invention for retrieving the availability mode of a subscriber, h this non-limiting example, a request is received

from subscriber B inquiring the availability status of subscriber A (step 502). Next, the

request is directed to subscriber A's agent along with the information that subscriber B is

the one asking for availability information (step 504).

Next, subscriber B's policy is obtained, the policy comprising both the routing

policy and preference retrieval steps 506 and 507. hi step 506, the agent retrieves subscriber

A's current routing policy, which indicates what the current relevant devices are currently

used by subscriber A, their order of preference, and the media types supported in each of them. It should be noted that each subscriber always has at least one routing policy selected.

However, it should also be noted that subscribers are able to have more than one routing policy, thereby allowing them to differentiate policies based on groups (for example, for

mom my routing policy is 'sleeping' and for friend it is 'at home'). In step 507, subscriber A's agent retrieves the preferences of subscriber A.

Subscriber A's preferences file includes information regarding: whether subscriber A allows

others to receive the availability mode, whether the availability mode should be shown to people in the contact list, and who are the people that cannot have access to the availability

mode.

hi step 508, subscriber A's agent retrieves the presence information of all of

subscriber A's devices. The presence information can be retrieved from all of subscriber

A's devices, but it should be noted that it is not obligatory that each of subscriber A's

devices transmit its presence. For example, subscriber A's client 1 may be in presence type 'online', 'offline', or 'away' and subscriber A's home telephone may be in presence type 'unknown' or 'busy' and the agent is able to retrieve this information upon its own request,

or whenever the presence information of the device has changed, or whenever the device decides to send its presence information to the agent. One skilled in the art should

recognize that there is no limit on the number of presence types that can be defined in conjunction with the present invention and should not be restricted by various ways of retrieving the presence information. Additionally, in an extended embodiment, the agent

asks a device's current presence when the information is needed.

hi step 510, the agent calculates subscriber A's availability mode for subscriber B. For

example, if subscriber A's current policy is 'out of reach', regardless of what the presence of the information contained in steps 506-508 affects the availability mode of subscriber A and

( is sent (pushed by a server active verb) to all subscribers having subscriber A's on their

contact lists.

Described below is an example of a change to presence, privacy settings and policy wherein subscriber A's network phone 1 is 'offline', subscriber A's home telephone

presence is 'unknown', subscriber A's office phone is 'busy' and subscriber A's network

phone 2 is 'online'. Furthermore, subscriber B is in subscriber A's contact list and vice versa. Additionally, subscriber B is not in subscriber A's ignore list and thus allows anyone to see his availability mode. Subscriber A's current policy is 'network phone' as described

above, hi the situation as described, subscriber B sees subscriber A as available for text chat

and audio conversation.

In the event subscriber A's client 1 goes 'offline', subscriber A's agent receives an

indication, calculates subscriber A's availability mode and sends the information to

subscriber B. h this instance, subscriber B will see subscriber A as available for audio, but

not for text chat. If, on the other hand, subscriber A's home phone changes the mode to 'busy', subscriber A's availability mode will be recalculated and subscriber B will see him as available neither for audio nor for text chat. But, if subscriber A's network phone 1

changes the mode from 'offline' to 'online', subscriber B subscriber A as being online

again. Now considering the instance wherein subscriber A adds subscriber B to his ignore

list and sets the preferences to not allow people in the ignore list to see the availability

mode, hi such a case, agent will recalculate subscriber As availability mode, and subscriber

B will see subscriber A as not available for audio conversation and not available for text

chat.

On the other hand, if subscriber B is deleted from subscriber A's ignore list,

subscriber B sees subscriber A as available both for audio and for text messaging. But, if subscriber A changes his policy (either by using the web, the Network Phone, or any of his

other devices) to be 'text only', this information is received by the agent and sent to subscriber A's relevant contacts.

Figures 6a and 6b collectively illustrate a GUI implementing the present invention. Figure 6a illustrates a screenshot of the present invention interface for indicating availability modes associated with subscribers, hi this example, the subscriber's name 'Anonymous' is

currently logged onto server 422 (online)(Figure 4) from location 'PC. Figure 6b illustrates

an expanded screenshot of the interface in Figure 6a. Panel 602 is used to connect to other

subscribers who are currently logged on to server 422 (Figure 4) and are capable of

receiving network-based voice (e.g., VoIP). Panel 604 allows for audio related controls and

panel 606 allows for displaying statistical information regarding audio and video parameters. Panel 608 allows various administration features, such as adding various other Figure 7 illustrates panel 700 for adding a subscriber in the contact list. Field 702 in

panel 700 allows subscribers to add another subscriber to their contact list by providing their

login names associated with server 422. Optionally, subscribers in contact list can also be

given nicknames (entered in field 704) for the ease of recognition. Figure 8 illustrates the

interface after a couple of subscribers ('Anonymous 1 ' and 'big cb-ris') have been added. It

should be noted that icons 802 and 804 (associated with subscriber 'big cb-ris') are visually

different from icons 806 and 808 (associated with subscriber 'Anonymous 1') because subscriber 'big chris' is online and is allowing text and voice messages from subscriber

'anonymous'. The interface illustrated in Figure 7 dynamically updates the availability of subscribers such as 'big chris', based on their routing policy and their desire to reveal their

identity. Furthemiore, the interface visually modifies icons (802 and 804) to indicate various availability modes associated with subscribers such as 'big chris'.

Thus, the present invention provides for a method and system for determining and

informing subscribers and requestors regarding the availability mode of subscribers (connected to a server) based on subscriber routing policies plus preferences and presence of devices. The routing policy used in conjunction with the present invention is configurable

by the subscriber to discriminate between various groups, thereby providing for the display

of different policies for different people or groups of people. A system and method has been shown in the above embodiments for the effective

implementation of selectively revealing a subscriber's availability based on the identity of

the requestor. While various preferred embodiments have been shown and described, it will

be understood that there is no intent to limit the invention by such disclosure, but rather, it is intended to cover all modifications and alternate constructions falling within the spirit and

scope of the invention, as defined in the appended claims. For example, the present invention should not be limited by software/program, computing environment, specific

computing hardware, number of subscribers, number of media types, number of routing

policies or number or type of client devices.

The above enhancements and described functional elements are implemented in various computing environments. For example, the present invention may be implemented

on a conventional IBM PC or equivalent, multi-nodal system (e.g., LAN) or networking

system (e.g., Internet, WWW, wireless web). All programming, GUIs, display panels and screenshots, and data related thereto are stored in computer memory, static or dynamic, and

may be retrieved by the subscriber in any of: conventional computer storage, display (i.e., CRT) and/or hardcopy (i.e., printed) formats. The programming of the present invention

may be implemented by one of skill in the art of server based application and protocol-based network communications programming.
