`
`BACKGROUND OF THE INVENTION
`The invention relates to setting up a conference call especially in
`digital communications systems.
`In message chatting, a chat group is formed in a ·communications
`server by subscribers registered into a certain group. After the server has
`received a message sent by one of the members in the group, it sends it on to
`all other active members in the group.
`Conference calling refers to a teleconference based on telephony
`between three or more participants,
`in which several subscribers are
`connected to the same call. Such a call is often referred to as a conference
`call or a group call. Conference calling can be set up either by the operator or
`the user itself.

`
`BRIEF DESCRIPTION OF THE INVENTION
`It is an object of the invention to add to a message chat group the
`option of also setting up a conference call between the members of the group.
`This object and other advantages provided by the invention are
`achieved by a method as claimed in claim 1, a communications system as
`claimed in claim 5 and a messaging server as claimed in claim 9. Preferred
`embodiments of the invention are disclosed in the dependent claims.
`The invention is based on joining message chatting and conference
`·Calling operationally to each other in such a manner that it is possible to move
`from message chatting in a simple way to a conference call between the
`members of the group by transmitting to the messaging server a pre-defined
`25 message which functions as a conference call request. The server reacts to
`the conference call request by setting up a conference call between the active
`members of the group. When the call is ended, chat mode is re-established.
`The functionality of a conventional message chat group can be significantly
`expanded by means of the invention. The invention makes it possible to set up
`arbitrary chat groups which can easily change from message chatting to
`conference calling and back. Chat groups can be defined by the users or the
`service provider, thus making them independent of communications operators.
`A conference call is, however, established between a pre-defined group with
`one message without any complex conference call definitions. at the beginning
`of the call. The server can, however, utilise the conference call solutions

`existing in the communications network in the form of an intelligent network
`service, for instance, which the server triggers when receiving said message.
`The server can also itself act as a service switching point for the conference
`call, in which case it is completely independent of the communications
`network. One advantage provided by the invention is that it does not require
`any special terminal support, but works on all terminals capable of transmitting
`and/or receiving messages.

`
`DETAILED DESCRIPTION OF THE INVENTION
`Figure 1 shows a general system chart of a communications system
`to which the invention can be applied. Five subscribers ANN (MS1, Mobile
`20 Station 1), HENRY (MS2), LISA (MS3), JOHN (MS4) and MAX (MS5) are
`connected to the communications system, in this case a digital mobile system,
`i.e. a GSM (Global System for Mobile Communications) system. The mobile
`stations MS1 to MSS can be conventional mobile stations equipped with a
`short message service. Although in the following the invention will be
`described by means of a short message and a short message service, a
`message can comprise e.g. at least one of the following messages: a short
`message, an instant message, an e-mail message, a multimedia message, a
`unified messaging message, a WAP (Wireless Application Protocol) message
`or a SIP (Session Initiation Protocol) message. The mobile stations can also
`be mobile stations equipped with e.g. an instant message, an e-mail message,
`a multimedia message, a unified messaging message, a WAP (Wireless
`Application Protocol) message or a SIP (Session Initiation Protocol) message
`service.
`
`25
`

`
`The GSM system can be directly connected to the Internet. In
`addition, the GSM system is connected to a quick message server SERVER of
`

`the invention. The quick message server SERVER is connected to the GSM
`network in the manner of an ordinary short message switching centre, but it is
`also possible to have speech channels connectable from the GSM network to
`the server SERVER for setting up a conference call as described. The quick
`5 message server can also be connected to an intelligent network, for instance
`to an intelligent network service control point SCP, in which case the quick
`message server can initiate a conference call in the GSM network as an
`intelligent network service. A work station (WS) represents an Internet work
`station, by means of which a user or a quick message service provider can
`through the Internet user interface of the server SERVER modify the group
`settings of the server or participate by means of an IP telephone (Internet
`Protocol, Voice over IP) in the operation of the group . A user can instead of
`the work station WS also use a conventional mobile station MS which has an
`Internet browser and the possibility to set up a data link to the Internet. A user
`can possibly also modify his or her user data by means of short messages
`instead of or as an alternative to the Internet user interface. A database DB
`represents a database residing in the quick message server, for instance.
`Figure 2 shows an example of the more detailed structure of the
`database DB. Altogether five subscribers, their alias names being Henry, Lisa,
`John, Max and Ann, have registered into two short message chat groups G1
`and G2. The user names, telephone numbers, status data and any possible
`notable matters (note) are stored for each group member in the database.
`When the operator allows it, a subscriber can activate or generate a
`quick message group by means of a specific GENERATE message. According
`to an alternative mode of operation, the service provider can set up the group
`through his own user interface. This is usually done when one member of the
`group orders the service and gives the names of the other .group members.
`For a flexible use of the service, it is, however, preferable that one or more
`group members are named as masters who are entitled to change group
`30 members and their rights. This can preferably be done in a fixed work station
`WS by means of an Internet browser by accessing the VWVW (World Wide
`Web) site of the server SERVER. At this time, the access rights of the user are
`for
`instance.
`requesting a user name and password,
`checked by
`Correspondingly, the changes can be made through a mobile station with a
`browser and a possibility to access the Internet. The original registration of the
`group can have been made in the same manner through the Internet following
`
`25

`

`

`wo 02/21816
`
`PCT/FIOl/00781
`
`4
`the instructions on the Internet pages of the service provider. The user making
`the registration is then registered as the master when receiving the user
`names and passwords. An advantage of this is that less personnel is required
`by the service provider. Alternatively, the subscribers can be registered as
`groups through the Internet, for instance, according to the instructions on the
`Internet pages of the service provider. It is also possible that the master has at
`least in a restricted manner the right to modify the group data by means of
`short messages. In addition, all group members have the right to register as
`active or inactive by sending a special Login message.
`In Figure 2, Henry, Lisa, John and Ann have sent to the group's
`address, i.e. telephone number 050-123456-2, an activating short message
`LOGIN, so they are in active chat status (logged), but Max has set his status
`to "absent". This status is defined so that text messages can be sent to him,
`but since he is not in an active status, he does not want to take part in a
`possible conference call set up from the short message chat. Information on
`Max's absence and its cause may be transmitted in a reply short message to
`the other group members when they send short messages to the server or
`initiate the conference call. Other statuses than those presented here are also
`possible.

`
`The database DB of Figure 2 shows two groups, namely the groups
`G1 and G2. The first group G! Includes Henry, Lisa and John. The second
`group G2 includes Max and Ann in addition to the members of the first group.
`When the members of the group G1 then communicate with each other, only
`the members of the group in question are allowed to participate. Likewise,
`25 when the members of the group G2 communicate with each other, only the
`members that belong to the group G2 are entitled to participate.
`Alternatively, when establishing a conference call, the sender of the
`CALL message can, if necessary, define the group members with whom he
`wants to talk. This can be done for instance by sending a short message CALL
`30 ALIAS, wherein ALIAS represents the names of the group members. For
`instance, CALL LISA HENRY ANN shows that the conference call is to be
`established with the members LISA, HENRY and ANN.
`Different groups naturally have different addresses. Thus, in Figure
`2, the address of the group G2 differs from the address of the group G1. From
`the above, it can als? be noted that a user can simultaneously belong to more
`than one group and thus receive short messages, for instance, from more than
`
`35

`one chat group. In conference calling, a user belonging to more than one
`group can change from one conference call to another.
`Figure 3 shows in a flow chart the action that can be taken before
`starting a short message chat. In step 3-2, a server SERVER is established in
`the short message switching centre of the mobile system, for instance. The
`quick message server in question can be established either temporarily or
`permanently. In step 3-4, a group for short message chatting is set up in the
`above-mentioned server by allocating memory space for it from the server.
`After this, the service provider can open the group in step 3-6.
`Short message chat groups can be closed or open groups.
`Examples of closed groups include a company's board of directors, a club or a
`basket ball team. An example of an open group is a chat line open for
`everyone (0700 chatting).
`After establishing the server, setting up the group and opening the
`group, the group members can, in step 3-8, be registered to the quick
`message server in question as described above, for instance. Figure 4 shows
`a flow chart of a short message chat. In step 4-2, one member of the group set
`up in the quick message server sends to the address of the group set up in the
`quick message server a pre-defined short message, one co.ntaining text, for
`instance. In step 4-4, the server receives the short message and sends it in
`step 4-6 immediately to all subscribers registered in the group. The sender of
`the text message need thus not send the text message to each member of the
`group separately, but he or she sends the short message only once to the
`quick message server which distributes it to the other subscribers of the group.
`Before sending a short message, the right of the member to send
`the short message can be checked. The routine can contain checking, for
`instance, if the member sending the short message has enough money to
`send short message(s). The quick message server can also have different
`check routines of checking, for instance, which group member is allowed to
`receive a message transmitted by a certain person. It is thus possible to have
`open and closed groups within open or closed groups. In addition, members of
`different groups can have priorities related to short message sending or
`receiving.

`
`According to the invention and
`its preferred embodiments, a
`conference call can quickly and simply be set up between persons registered
`to a quick message group. The flow chart in Figure 5 shows this conference

`
`call set-up. In step 5-2, a group member sends to the address of the server,
`for instance E.164, a short message CALL. The quick message server can
`then check in step 5-4 whether the subscriber sending the set-up message is
`registered as a member of the group in question and/or whether the member
`in question has the right to send this set-up message. If the member in
`question is registered and has the right to send the set-up message, the
`setting up of the conference connection is started. In step 5-6; the routine then
`checks if the first group member called by the server is active, in other words,
`does he or she want to participate in a conference call. Active status can be
`checked from the subscriber's status information, for instance, by sending to
`the subscriber in question a text message and by waiting the subscriber's
`reply to this or by calling the subscriber and waiting for an answer.
`If the called member wants to participate in the conference call, the
`call is set up in step 5-8 utilising an intelligent network, for instance. The quick
`15 message server SERVER then triggers in the intelligent network service
`control point an intelligent network service which directs the GSM network to
`connect a speech connection for the called subscriber according to the
`instructions given by the service control point SCP, but leaves the call
`connection to wait for the connection of the other speech connections in the
`quick message server. After this, the server SERVER triggers a call set-up for
`all other active members of the group by performing steps 5-10, 5-6, 5-8, after
`which the intelligent network service directs the GSM network to connect the
`waiting calls into one conference call.
`Instead of the intelligent network service and the GSM conference
`call, the quick message server SERVER can first set up the individual calls
`between the server and each active group member and then connect the calls
`to each other as a conference call in the server. This requires the possibility of
`setting up speech connections from the GSM network to the server and some
`kind of a switch in the server, but, on the other hand, the server then does not
`need a intelligent network interface or an intelligent network service. In such a
`case, the server of the invention is as independent as possible of the actual
`communications network.
`If the subscriber sending the conference call set-up message is not
`registered or the member in question does not have the right to set up the
`conference call in question, the initiation routine of the conference call is
`ended in step 5-15. If the called subscriber is not active, the routine moves
`
`20
`
`25
`
`30
`
`35
`
`Page 8 of 18
`
`

`

`wo 02/21816
`
`PCT/FIOl/00781
`
`5
`
`7
`from step 5~6 to step 5-10, in which the routine checks if there are other users
`in the group that could be called. If there are other such users, the routine
`moves back to step 5-6.
`If the number of simultaneous subscribers is limited by the number
`of subscribers in the conference call, this can, at the same time, limit the
`maximum size of a short message chat group.
`The conference call is ended when all subscribers end their calls in
`the usual manner from their mobile stations. A single subscriber can exit the
`conference by ending his or her call while the other group members continue.
`10 When the conference call has been ended, the subscribers can continue
`exchanging short messages or at any time initiate a new conference call as
`described above.
`Billing the method of the invention and its preferred embodiments
`can be implemented in may ways. These include:
`- the sender of the initiating CALL message pays for all calls,
`- the participants in the conference call pay their own share when
`they answer,
`- a fixed monthly fee is used.
`The group members can thus move from short message chatting to
`conference calling simply by one short message. Exiting the conference call is
`also simple. It can, for instance, be done by each participant ending his or her
`own call or switching off his or her phone. Alternatively, one group member
`sends to the server address a message END, whereby the quick message
`server ends the conference call for the entire group or a part of the group.
`25 Various permission and priority checks can also be included in the ending
`routines of a conference call.
`One advantage of the invention is that it does not require any
`specific terminal support, but works with the present terminals capable of
`sending and/or receiving short messages.
`It is obvious to a person skilled in the art that while technology
`advances, the basic idea of the invention can be implemented in many
`different ways. The invention and its embodiments are thus not limited to the
`above examples, but may vary within the scope of the claims.
