`(54) Title: ANONYMITY IN A PRESENCE MANAGEMENT SYSTEM
`
`IIIIIIIH1IIIIIH
`
`WO 01/45343 A2
`
`(57) Abstract: A presence management system is described whereby connections between watching parties and watched parties in
`a multiple access communications network are managed. When the presence management system receives a contact request from
`a watching parly it determines whether the required watched party is available for contact. The system then provides information
`about this to the watching party who made the request. The presence management system chooses the best mode of communication
`(e.g. email or fax) taking into account the watched parties preferences and details about the facilities available to the watching party.
`If, the presence management system informs the watching party that the watched party is unavailable, the watching party is able to
`set up a monitor. In determining whether the required watched party is available for contact, the presence management system uses
`stored information about the watched party, information about the required connection (e.g. size and type) and also rules.

`
`Field of the Invention
`This invention relates to a presence management system for
`use in a multiple access communications network.
`
`Description of the prior art
`Telecommunication users of today are faced with ever
`increasing choice over how they communicate. A typical user
`has several different kinds of communications terminal such
`as mobile telephones, fax machines, personal computers, lap
`top computers. Also a typical user also often has more that
`one of a given type of communications terminal, for example,
`more than on- E-mail account, or home and work telephone
`numbers. This produces complexity and confusion both for
`senders and receivers of communications.
`Receivers of communications have to work hard to field
`all incoming communications and such users often find that
`interruptions from alerts, such as telephone calls and
`instant messages, are intrusive.
`Typically, receivers of communications have little
`control over what communications are received, at which
`times, and in which modes. In face to face communications,
`humans are able to control the degree of interaction which
`they allow with particular people or groups. However, with
`today's communication networks the degree and resolution of

`
`the control of electronically mediated communications is much
`less. For example, telephone numbers are often fully public
`(in a directory) and are typically issued on demand to others
`who explicitly ask and know the full address. Also, a
`telephone number, once released to others, has continuing
`validity unless the telephone number is changed at great
`inconvenience and expense. Similar problems apply for email
`addresses. This means that it is easy for others, such as
`salesmen or nuisance callers to contact you more times than
`desired. In order to prevent this problem, telephone.numbers
`and email addresses may be withheld but this gives the
`disadvantage of isolating the "owner" of the telephone number
`or email address.
`Senders of communications also experience problems
`because they are often unsure about which mode of
`communication to use at a given time for a particular
`destination. In order .to determine the most appropriate
`method of access there are many factors to be considered.
`These include factors to do with the sender such as what they
`are trying to communicate and factors to do with the receiver
`such as where. the intended recipient is and what they are
`doing at the time.
`Two examples of instant messaging services are now
`described:
`
`Microsoft. Network (MSN) messenger service
`MSN messenger service is an instant messaging service
`for use on the Internet. Users are able to identify when

`
`PCT/GB00/04512
`
`3
`
`others are online and to send and receive instant messages.
`By identifying when others are online it is possible to send
`an instant message to other online individuals or to
`communicate with several other online individuals at once.
`In this way the communication and messages are more "real
`time" than conventional email for example, where an email
`message may simply remain in an individual's email inbox for
`some time before it is accessed. The service enables a user
`to identify when another party in an internet conversation is
`typing at their computer terminal keyboard. That is, using
`the instant message service it is possible to "talk" to more
`than one person at a time in a similar way to an online chat
`session. The user is also able to control which other
`parties are able to identify or "see" when the user is online
`and also to control who is able to send messages to the user.
`In this respect the MSN service differs from conventional
`online chat programs. Automatic notification of receipt of
`messages is provided. However, instant messages in MSN
`messenger service have a temporary quality. Unless the user
`deliberately saves these messages they are lost when the
`message service is shut down. This contrasts with
`conventional email messages in most email systems which
`remain until a user actively deletes them. Information about
`MSN messenger service is provided on the Internet at
`http://messenger,msn.com.

`
`ICQ is an instant messaging service for internet users.
`It is a program that enables users to identify others who are
`online and which alerts users when specified individuals log
`onto the ICQ service. This removes the need for a directory
`search to be made each time a user wants to communicate with
`a specific person.
`Using ICQ, messages, files and web pages can be sent to
`other online users of ICQ in real time and ICQ also supports
`chat, voice, message board, data conferencing and internet
`games. When a new user installs ICQ the user is prompted to
`register at a server which is connected to a broad network of
`other servers spanning the internet. In the registration
`process the user receives a unique ICQ identifier number and
`is able to enter personal information. When the registered
`user logs onto the Internet the ICQ system detects this and
`allows other ICQ users to recognise that that user has logged
`on. The registered user is able to compile a list of friends
`and associates (these friends and associates must also be
`registered with ICQ or a compatible instant messaging
`service) and the ICQ system determines when these individuals
`are logged onto the internet. Alerting messages are sent to
`the user to inform him or her when members of the list of
`friends and associates sign on or off the ICQ system. Users
`are also able to control who contacts them and to hide their
`presence on the internet when this is required. information
`about ICQ is given on the Internet at http://www.icq.com.

`
`Some instant messaging services include so called "buddy
`lists" which are lists of other users of that instant
`messaging service which have been selected by an individual
`user as being those of interest. The individual user is then
`informed whether or not the members of the "buddy list" are
`currently using and available for contact via the instant
`messaging service. Such buddy lists are essentially
`attributes of the owning user and do not have any autonomous
`status in the instant messaging system, thus playing only a
`passive role therein.
`Other instant messaging systems such as America On
`line's instant Messenger (trade mark) offer broadly similar
`capabilities to ICQ.
`Known instant messaging systems such as MSN and ICQ do
`not deal with multiple access communications networks and are
`based on the internet only. This is disadvantageous because
`the functions of the instant messaging systems are only
`available via the internet.
`Unified messaging systems are known, such as Nortel
`Network's own product CALL PILOT (trade mark). This enables
`fax, email and voice mail messages to be received via a
`single "in box" and users are able to set up filters to allow
`only certain messages to reach them. For example, users are
`able to listen to textual email messages converted
`automatically into speech using their mobile telephone and
`are able to filter out non-urgent messages. However, this is

`
`not a presence management system and does not monitor the
`activity of users on a communications network.
`Products are available which act as communications
`network based "secretaries" to take a user's calls. For
`example, WILDFIRE (trade mark) produced by Wildfire
`communications, Inc and PORTICO (trade mark) produced by
`General Magic, Inc. The WILDFIRE product uses speech
`recognition to help users manager their phone, fax and email
`communications. This product dials outgoing calls, announces
`callers using a voice recording that is played back, records
`contact details and is able to route incoming calls to any
`telephone specified by a user. However, this system is not a
`presence management system because it does not obtain and
`manage information about the activities of users and monitor
`their "presence" on the communications network. Also, it is
`not an instant messaging system and does not enable users who
`are trying to contact another user to obtain information
`about the best mode and time to do this. Details about the
`WILDFIRE product are available on the Internet at
`wiw.wiIdfire.com. Details about PORTICO are available on the
`Internet at www.generalmaqic.com. PORTICO is similar to
`WILDFIRE and is limited in the same respects as PORTICO.
`It is accordingly an object of the present invention to
`provide a presence management system which overcomes or at
`least mitigates one or more of the problems noted above.

`
`This provides the advantage that a presence management
`system provides a connection address for a watched party
`under controlled conditions, thus enabling the watched party
`to control access to that connection address by making use of
`the presence management system. In one example, the
`connection address provided is valid only for a limited
`number of connections or for a limited time. In this way,
`connection addresses can be issued to watching parties such
`as sales people whilst at the same time limiting the ability
`of that watching party to contact the watched party. In
`another example, the connection .address provided is used by
`the presence management system to forward the connection
`request direct to the watched party. This prevents the
`watching party from gaining access to the watched party's
`direct address.

`Detailed description of the invention
`Embodiments of the present invention are described below
`by way of example only. These examples represent the best
`ways of putting the invention into practice that are
`currently known to the Applicant although they are not the
`only ways in which this could be achieved.
`The term "multiple access communications network" is
`used to refer to a communications network which comprises
`several different types of communications network and which ■
`can be accessed using a plurality of different types of
`terminal which also comprise part of the communications
`network. The communications network can be accessed by a
`plurality of such terminals at any one time. For example, a

`
`public switched telephone network that is connected to a
`mobile telephone network is a multiple access communications
`network. This is because the overall network is made up of
`two different types of communications network and the overall
`network can be ' accessed using many different types of
`terminal such as a conventional telephone handset, a
`facsimile machine, a mobile telephone or a modem. A multiple
`access communications network can be thought of as a
`"federated" network and the component communications networks
`within a multiple access communications network can be
`connection-less networks (e.g. the’ Internet) or connection
`oriented networks (e.g. public switched telephone networks).
`The term "access communications network" is used to
`refer to a communications network which is situated on the
`edge or periphery of a core communications network and
`through which users . gain access to the core communications
`network.
`The term "presence management system" is used to refer
`to an automated system for use in a communications network
`which provides a single point of presence for a user of that
`communications network. A point of presence is a source of
`information about whether a user is available for contact on
`a communications network, where that user is located on the
`network, and in which mode that user should preferably be
`contacted in. A presence management system provides a single
`point of presence despite the fact that a user has more than
`one terminal for accessing the communications network in

`
`different modes and possibly by different access
`communications networks. A presence management system also
`provides context information rather than just raw presence,
`information. Raw presence information is unprocessed
`information about the availability, location and capability
`of a user on the communications network. A presence
`management system processes raw presence information
`according to rules or other pre-specified criteria about
`users in order to provide context information that is simpler
`and easier for human operators to understand.
`Figure 1 illustrates a presence management system 10
`which is connected to a multiple access communications
`network 11. Also connected to the multiple access
`communications network 11 are a plurality of watching parties
`12 and a plurality of watched parties 13. In Figure 1, each
`watching party 12 and each watched party 13 is shown as
`having a single connection . to the multiple access
`communications network 11. However, this is not necessarily
`the case. For example, a watched party 13 can be an
`individual who has access to the multiple access
`communications network via a mobile telephone, a lap-top
`computer and via two different personal computers.
`Similarly, a watching party may have more than one connection
`to the multiple access communications network.
`Each watched party 13 registers with the presence
`management system 10 and is given a unique presence
`management identifier. During the registration process each

`
`watched party 13 enters personal information which is
`recorded in a store 14 in the presence management system 10.
`For example, this information includes the watched party's
`email address, telephone number, and other contact details.
`Context information is also included, such as information
`about whether the watched party is a home worker or a
`travelling salesman. Details about the watched party's
`preferences are also recorded, such as which modes of
`communication are preferred at which times, for example,
`email messages may be permitted at any time, whilst telephone
`calls may only be preferred during work hours. Some of this
`information is stored in the form of rules 15 within the
`presence management system. Some rules may be default rules
`that are preconfigured and others are entered by watched
`parties. However, it is not essential to store this
`information in the form of rules 15. Any suitable form for
`the information may be used.
`A first input 16 is provided to the presence management
`system 10 from the multiple access communications network 11.
`This input 16 is termed an events input and may be provided
`in the form of an events gateway (described in more detail
`below). Via this first input 16 information about events
`that occur in the multiple access communications network are
`provided to the presence management system 10. In this way
`events that are associated with the watched parties 13, for
`example, the event of a watched party logging onto the
`Internet, are accessed by the presence management system 10.

`Other examples of events include movement of a watched party
`between cells of a cellular communications network, remote
`login events, or keyboard presses by a watched party on an
`Internet terminal.
`If a watching party 12 requires to contact a watched
`party a contact request is sent to the presence management
`system 10 by the watching party 12. The contact request
`reaches the presence management system via a second input 17
