Description
PRESENCE INFORMATION METHOD AND SYSTEM
Field of the Invention The present invention is directed to a method and a system permitting a user of a legacy telephone system, i.e. a Public Service Telephone System (PSTN), an Integrated Service Digital Network (ISDN), or a Mobile telephony system (MTS), to publish information about his or her presence or availability in an interconnected presence system, for example and preferably to an Internet presence service.
Prior Art In the environment of telephony there is a strong interest in making a call succeed, not only from a user's point of view - he/she wants to communicate with another user -but also from that of the service provider, i.e. the need to generate revenue. There is also an interest in preventing unsuccessful calls. Having a calling user re-dial a number again and again -either because the called user is busy or because he/she does not answer - is unproductive, because unsuccessful call attempts are usually not charged although they consume a lot of network resources.
Several supplementary services could be available to help a calling user in the cases mentioned above, such as among others, Completion of Call to Busy Subscriber (CCBS), Completion of Call on No Reply (CCNR), call back, etc.
To implement those services, the system usually monitors the status of the called user and automatically retries the call when the called user is no longer busy (in case of CCBS) or when the called user is available again (in case of CCNR).
However, there is substantially no deployment of such supplementary services in public telephone networks because these services would require complicated interaction between the users and the switches, and between the switches themselves. Even in a more modern Private Branch eXchange (PBX) environment it does happen that such services are offered only to those users that are connected to the same PBX.
"Presence" is a mode of communication that has recently become popular in the Internet.
It is a service that allows a user "A" to declare his interest in the presence or availability ~.~ . ~..~.~,:~ . . ~ ,,.~.~ .~,. .w.m ~.~.. ~_ .. . ...... . . .....
information of another user "B". >:Jser "A" is said to subscribe to the "presencc inli,nnation"
of uscr "B". The terminal of user "B" publishes "presence information" about user "B". 'I'he service delivers notifications to "A" each time the "pre.sence infnnnation"
of'"t3" changes.
In wnncction with the Inteniet, for example, "presence informatiom" about a user is information about the user's prescnce or in a tnorc restricted sense - about his/her degree of availability for intcra(-,tion with, the telecomnrunication system. For example, such infornZation may include whether or not the user is active in the Internet.
Aims and Ubiects of the lnvention ] 0 However, to the best of applicant's knowledge, it is not possible, at presetit, for a user of an Internet presence service to obtain similar or equivalent presence information about a user of a legacy teleph.onc system.
Accordingly, it is an object of' the invcntion to provide for a niethod and system fi)r providing an indication of'availability of a user of a legacy telephoiae system to a user of an interconnectcd presence service, e.g. an Intemet presence system.
More specifically, the present invention aims at providing a method and system that permits a user of a legacy telephone system to publish ini'armation about hcr/his availability for wmmunica.tion with other users of any interwnnected presence system, e_g.
such that an lnternet user who has subscribed to the availability inlfonnation of a legacy telephone user could then be notified about the availability ol'sucli uscr.
Brief Sammary of the Inverttioit This object and fu.rther advantages will achieved, according to a first general embodimettt of the invention by a incthod of operatitig an availability service.
According to a second general cmboditnent, the invention provides for a systcnt of operating an availability service.
According to a third gcneral embodinient, the invention provides for aii availability service program for implementing operation if#'an availability service.
According to a fiuther embodiment, the invention provides for a modulc for opcratins an availability service.
C;T Iry-1999-003d 2 1)efYniti2n of Terrrts and Discussion of Preferred llSmbodirrcents C7eneraliy, legacy telephone systems collect presencc infonnation about their users but for internal purposes and wittiout offering a presence service to thc."ir users.
For examplc, a PSTN is able to monitor the status of a telephone line of a subscriber and determine whether the user is busy or not. The event that a telephone line goes from busy stute to free state is a piece of presence information for use according to the invention. It is of interest because it indicates that during a subsequent pcriod of time, e.g.
the next couple of seconds or minutes, there is a high likclihood that the user is able to answer a call.
Further, networks for mobile telephony provide a procedure fior the inobilc telephones to register with the base station before ttie mobiic telephone can make or receive a call. The network kceps track of the registration status. The fact that a mobile telephone is registered and not involved in a call also is another piece of information for use in the present invention.
Tt is of interest because it indicates that there is a high likelihood that the user is able to answer a call.
Generally speaking, a P'1'SN user is either busy or not. For the present invention, a signal indicating transition from busy to not busy indicates that during a subsequent period of time -c, there is a relatively high probability that the user will answer an incoming call and is present in the sense of the invcntion. It should be noted, however, that the term "presence of a user" does not necessarily imply actual physical presence but, rather, an indication of "availability" of a user. This distinetion is of importance because "pre5ence"
is a "digital"
concept in that a user is cither present, or he is not present, "Availability", on the other hand, could he said to be "graded" so that the a certain degree of a user's availability could he defined, e.g. a"high", "mediuni" or "low" degree of availability. For this reason, the term "availability sigiial" rather than "presence signal" is used herein even though both terms could he used synonymously as well.
CH9-1999-0036 j The following terms and concepts are used herein to define the presence or availability status of a PSTN:
- "Busy": a signal indicating that the user is currently involved in a call.
- "Probably Available": a signal indicating that the user has just been involved in a call and is now free, and that it is probable that the user will answer an incoming call.
This state or signal is termed a "high availability" state or signal, respectively, and will change into "availability unknown" after a certain time period "i" as defined below. Hence, - "Availability Unknown" is the state or signal indicating that the user has not been busy for a period of time > i.
The time period i is a configurable variable of the system according to the invention and can vary between minutes to hours. It is intended to characterize the fact that the longer a user is not busy, the smaller is the probability that he will be available for respond to an incoming call.
Additionally, the system or user may be provided with a means for "resetting"
the user's status to "unknown"; for example, the user may generate a specific signal, e.g. dial a certain code which is reserved for that purpose.
An important advantage of the presence or availability status that can be published by means of a system or method according to the invention is that the user can influence his status via a very simple interface: he can move his status to the state "probably available" by briefly picking up his telephone handset. There is no need for typing complicated and difficult to remember access codes For a user of a mobile telephone system, an additional state "Unregistered" is introduced to account for the registration status of the mobile user. Preferably, a user of a mobile telephone system should be able to set to a longer value for T than a PSTN user.
Detailed Discussion of the Invention The system according to the invention for publishing presence or availability of a user of a legacy telephone system to an Internet presence service (Presence Publishing System or PPS for brevity) will now be explained in more detail with reference to the enclosed drawings in which:
Figure 1 is a diagram of a system according to the invention;
Figure 2 is a transition diagram showing the presence status of a PSTN user;
Figure 3 shows the presence status of a mobile telephone user;
Figure 4 illustrates the components of a PPS according to the present invention; and Figure 5 illustrates a shift of the availability status.
Specifically, Fig. 1 is a diagrammatic representation of a system 1 according to the invention comprising a legacy telephone system 10. A plurality of terminals (T,...T,o) is connected with legacy telephone system 1, at least some of which, e.g. T,,T2, are subscribers to the availability service provided by the invention. Legacy telephone system 10 is connected via a gateway 12 with at least one presence system, e.g. a presence service of an Internet.
Gateway 12 may be used to run an availability service program for implementing operation of the availability service according to the invention; this special program is designed to continuously monitor each subscriber terminal T,,Tz for a change of a connect status of the subscriber terminal from high availability to availability unknown and for causing transmission of a status change signal when such change happens; further the program is designed to register the pre-selected period of time i for terminating the availability signal.
Fig. 2 shows the transition diagram of the presence status of a PSTN user while Fig. 3 shows the presence status of a mobile telephone user. A new state "Unregistered" is introduced to account for the registration status of the mobile user. Another difference is the value of i which can be set to a longer value than the one of PSTN user.
The advantage of the presence or availability status so defined is that the user can influence his status via a very simple interface: he can move his status to the state "high availability" by picking up his telephone handset briefly, and there is no need for typing complicated and difficult to remember access codes.
Figure 4 ilhistrate:t the compotients ttecded for publishing the presence infornsation of a telephone user to an Internet presence service. Assuining the existence of an Internet pretienec service consisting o(:
- multiple presetice servers tin= the storage and distribution of presence information, and - multiple presence clients publishiag and aecessing presence information to and from the server. The specifieation of suc.h a presence service(s), in particular of the necessary client-server and scrver-server protocols, is known to those expcrienced 'ui the art and needs no furthcr elaboration. Fut-ther, reference is made to US2001/0053213 published on Dcccmber 20, 2001. '1'he general esseiitial requirement for such a preserlce service is that it has to be able to support the kind of presence or availability information defined hcrein_ Further, assutining that the local exchange - to which the subscribed t.clcphone user is attached - is itivolved by providing the following functions:
- to constantly monitor the status of the telephone users attached to it, and - to indicate to the "gateway the events "not busy" (not aCtive) and "busy"
(active).
Based on the events reccived from thc local exchange, the gateway will construct the presence status of a telephpne user as specified in Figure 2. It is to be notcd that timer is shown as being iunplemented in the gateway to siinplify the functions ot'the local exchange.
This, however, is not a critical requirement and the timer eould well bc itrlplemented in another part of the system e.g. the module reterred to above.
Furthermare, thc gateway will publish that presence status to lsiternct presence servers, for example by using the protocols of that specific Inteniet presence service.
An In.tertict user can now use a presence client to access the presence or availability information of a legacy telephone user stored in the presence servcrs. Based on this information it will then decide when to make a telephone call to the telephonc user, c.g. only when the telephone user is in state of "high availability".
It is to be noted further in this context that the legacy telephone user can control and detcrmi.ne where and by whom (or by whicl, terininal) his presence or availability information may be observed. For exar.nple, tltis can he achieved by a suitxble Inteniet presence client. The CII9-1999=0036 6 exact way of achieving this specific goal, however, is not believed to be an essential feature of the present invention.
A system similar to the one illustrated in Fig. 4 and explained above can also be defined for mobile users and could include the following differences/enhancements:
- the local exchange is replaced by the mobile switching system including the base stations;
- the presence information of a mobile user is as illustrated in Figure 3;
- the mobile switching system additionally reports to the gateway the events "registration" and "de-registration".
The system and method according to the invention can also be implemented such that the local exchange is not involved, i.e. it is transparent to the system according to the present invention.
The system components needed are the same as the ones in Figure 4, with the difference that the local exchange does not provide to the gateway the events "not active" (same as "not busy") and "active" (same as "busy"). Without those two pieces of information, the presence information of a telephone user needs be reduced, for example to the states illustrated in Figure 5.
Furthermore, the telephone user himself notifies the gateway about his status change.
Various means are known to those experienced in the art and the following examples represent a non-limiting selection.
Example 1 The user just dials the gateway, hears the ringing tones for a few times and hangs up. The gateway does not answer the call, but can derive who is calling from the calling party number included in the incoming SETUP message and marks the corresponding user as "probably available". The transition to "unknown" is triggered by a time-out and/or by a special code dialed by the user.
_ .,...,..m.,.~...~,.:~., ,~..,..,~.,....~...,.,..Y.,....~,..,_~ ...-....._.,.,.. .... , . _ _. __ Example 2 The user dials the gateway, waits until the gateway answers the call, and dials (e.g. via DTMF) a certain identification code. Based on the received identification code, the gateway can determine which user to be marked as "probably available". Again the transition to the state "unknown" can be triggered by a time-out and/or by a special code dialed by the user.
Furthermore from the calling number included in the SETUP message the gateway can publish to the Internet presence service the telephone number under which the user can be actually reached.
Thus the method adds a certain "mobility" dimension to the service.
Example 3 In this example, the methods of Example 1 and 2 are combined as follows:
A user employs the method of Example 1 if he is at home; his home phone number is registered as default in the gateway. Otherwise, he employs the method of Example 2 if he wants to be reachable under another number.
Example 4 An ISDN or mobile telephone user can use the SMS service to communicate with the gateway instead using the "inconvenient" DTMF method as described in example 2 above. In this case, it is possible that - in addition to his identification code - the user could also send a short message to the presence server if this feature is supported (it being noted that most current presence servers do not support that feature).
That message will then be distributed to all users who have subscribed to the presence information of the telephone user. An example for such a message is "I'm reachable only until 10:30".
It is further to be noted that the reduced presence information illustrated in Figure 4 can also be implemented by a system according to the first alternative discussed above.
In this case, - either the gateway function is integrated into the local exchange; in this case, a user needs only to dial the special codes for enforcing the state transitions), - or the local exchange just relays further the user's inputs to the gateway.
While the invention has been disclosed above by means of specific embodiments, it is to be emphasized that the scope of the invention is not limited to such embodiments, and that the scope of the present invention is to be construed on the basis of the attached claims.

This state or signal is termed a "high availability" state or signal, respectively, and will change into "availability unknown" after a certain time period "i" as defined below. Hence, - "Availability Unknown" is the state or signal indicating that the user has not been busy for a period of time > i.
The time period i is a configurable variable of the system according to the invention and can vary between minutes to hours. It is intended to characterize the fact that the longer a user is not busy, the smaller is the probability that he will be available for respond to an incoming call.
Additionally, the system or user may be provided with a means for "resetting"
the user's status to "unknown"; for example, the user may generate a specific signal, e.g. dial a certain code which is reserved for that purpose.
An important advantage of the presence or availability status that can be published by means of a system or method according to the invention is that the user can influence his status via a very simple interface: he can move his status to the state "probably available" by briefly picking up his telephone handset. There is no need for typing complicated and difficult to remember access codes For a user of a mobile telephone system, an additional state "Unregistered" is introduced to account for the registration status of the mobile user. Preferably, a user of a mobile telephone system should be able to set to a longer value for T than a PSTN user.
Detailed Discussion of the Invention The system according to the invention for publishing presence or availability of a user of a legacy telephone system to an Internet presence service (Presence Publishing System or PPS for brevity) will now be explained in more detail with reference to the enclosed drawings in which:
Figure 1 is a diagram of a system according to the invention;
Figure 2 is a transition diagram showing the presence status of a PSTN user;
Figure 3 shows the presence status of a mobile telephone user;
Figure 4 illustrates the components of a PPS according to the present invention; and Figure 5 illustrates a shift of the availability status.
Specifically, Fig. 1 is a diagrammatic representation of a system 1 according to the invention comprising a legacy telephone system 10. A plurality of terminals (T,...T,o) is connected with legacy telephone system 1, at least some of which, e.g. T,,T2, are subscribers to the availability service provided by the invention. Legacy telephone system 10 is connected via a gateway 12 with at least one presence system, e.g. a presence service of an Internet.
Gateway 12 may be used to run an availability service program for implementing operation of the availability service according to the invention; this special program is designed to continuously monitor each subscriber terminal T,,Tz for a change of a connect status of the subscriber terminal from high availability to availability unknown and for causing transmission of a status change signal when such change happens; further the program is designed to register the pre-selected period of time i for terminating the availability signal.
Fig. 2 shows the transition diagram of the presence status of a PSTN user while Fig. 3 shows the presence status of a mobile telephone user. A new state "Unregistered" is introduced to account for the registration status of the mobile user. Another difference is the value of i which can be set to a longer value than the one of PSTN user.
The advantage of the presence or availability status so defined is that the user can influence his status via a very simple interface: he can move his status to the state "high availability" by picking up his telephone handset briefly, and there is no need for typing complicated and difficult to remember access codes.
Figure 4 ilhistrate:t the compotients ttecded for publishing the presence infornsation of a telephone user to an Internet presence service. Assuining the existence of an Internet pretienec service consisting o(:
- multiple presetice servers tin= the storage and distribution of presence information, and - multiple presence clients publishiag and aecessing presence information to and from the server. The specifieation of suc.h a presence service(s), in particular of the necessary client-server and scrver-server protocols, is known to those expcrienced 'ui the art and needs no furthcr elaboration. Fut-ther, reference is made to US2001/0053213 published on Dcccmber 20, 2001. '1'he general esseiitial requirement for such a preserlce service is that it has to be able to support the kind of presence or availability information defined hcrein_ Further, assutining that the local exchange - to which the subscribed t.clcphone user is attached - is itivolved by providing the following functions:
- to constantly monitor the status of the telephone users attached to it, and - to indicate to the "gateway the events "not busy" (not aCtive) and "busy"
(active).
Based on the events reccived from thc local exchange, the gateway will construct the presence status of a telephpne user as specified in Figure 2. It is to be notcd that timer is shown as being iunplemented in the gateway to siinplify the functions ot'the local exchange.
This, however, is not a critical requirement and the timer eould well bc itrlplemented in another part of the system e.g. the module reterred to above.
Furthermare, thc gateway will publish that presence status to lsiternct presence servers, for example by using the protocols of that specific Inteniet presence service.
An In.tertict user can now use a presence client to access the presence or availability information of a legacy telephone user stored in the presence servcrs. Based on this information it will then decide when to make a telephone call to the telephonc user, c.g. only when the telephone user is in state of "high availability".
It is to be noted further in this context that the legacy telephone user can control and detcrmi.ne where and by whom (or by whicl, terininal) his presence or availability information may be observed. For exar.nple, tltis can he achieved by a suitxble Inteniet presence client. The CII9-1999=0036 6 exact way of achieving this specific goal, however, is not believed to be an essential feature of the present invention.
A system similar to the one illustrated in Fig. 4 and explained above can also be defined for mobile users and could include the following differences/enhancements:
- the local exchange is replaced by the mobile switching system including the base stations;
- the presence information of a mobile user is as illustrated in Figure 3;
- the mobile switching system additionally reports to the gateway the events "registration" and "de-registration".
The system and method according to the invention can also be implemented such that the local exchange is not involved, i.e. it is transparent to the system according to the present invention.
The system components needed are the same as the ones in Figure 4, with the difference that the local exchange does not provide to the gateway the events "not active" (same as "not busy") and "active" (same as "busy"). Without those two pieces of information, the presence information of a telephone user needs be reduced, for example to the states illustrated in Figure 5.
Furthermore, the telephone user himself notifies the gateway about his status change.
Various means are known to those experienced in the art and the following examples represent a non-limiting selection.
Example 1 The user just dials the gateway, hears the ringing tones for a few times and hangs up. The gateway does not answer the call, but can derive who is calling from the calling party number included in the incoming SETUP message and marks the corresponding user as "probably available". The transition to "unknown" is triggered by a time-out and/or by a special code dialed by the user.
_ .,...,..m.,.~...~,.:~., ,~..,..,~.,....~...,.,..Y.,....~,..,_~ ...-....._.,.,.. .... , . _ _. __ Example 2 The user dials the gateway, waits until the gateway answers the call, and dials (e.g. via DTMF) a certain identification code. Based on the received identification code, the gateway can determine which user to be marked as "probably available". Again the transition to the state "unknown" can be triggered by a time-out and/or by a special code dialed by the user.
Furthermore from the calling number included in the SETUP message the gateway can publish to the Internet presence service the telephone number under which the user can be actually reached.
Thus the method adds a certain "mobility" dimension to the service.
Example 3 In this example, the methods of Example 1 and 2 are combined as follows:
A user employs the method of Example 1 if he is at home; his home phone number is registered as default in the gateway. Otherwise, he employs the method of Example 2 if he wants to be reachable under another number.
Example 4 An ISDN or mobile telephone user can use the SMS service to communicate with the gateway instead using the "inconvenient" DTMF method as described in example 2 above. In this case, it is possible that - in addition to his identification code - the user could also send a short message to the presence server if this feature is supported (it being noted that most current presence servers do not support that feature).
That message will then be distributed to all users who have subscribed to the presence information of the telephone user. An example for such a message is "I'm reachable only until 10:30".
It is further to be noted that the reduced presence information illustrated in Figure 4 can also be implemented by a system according to the first alternative discussed above.
In this case, - either the gateway function is integrated into the local exchange; in this case, a user needs only to dial the special codes for enforcing the state transitions), - or the local exchange just relays further the user's inputs to the gateway.
While the invention has been disclosed above by means of specific embodiments, it is to be emphasized that the scope of the invention is not limited to such embodiments, and that the scope of the present invention is to be construed on the basis of the attached claims.
