COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Server for supporting the establishment of calls 0~ The following statement is a full description of this invention, including the best method of performing it known to us: FHPSIYDCERNATP(W)12IXN17549J6 0
I
Server for Supporting the Establishment of Calls Field of the invention This invention relates to a method of controlling the establishment of a call from a calling subscriber to a called subscriber through a telephone network, and to a server and a computer product for supporting the establishment of calls between calling subscribers and called subscribers through a telephone network.
Background of the invention The invention is based on IN services (IN intelligent network) as are described, for example, in an article entitled "Intelligente Netze: Den Diensten gewidmet", Elektrisches Nachrichtenwesen, Vol. 65, No. 1, pages 38 to 43.
A service control point provides to a subscriber of a telephone network a personal number service, through which the subscriber can initiate a sort of call forwarding within the telephone network: The subscriber informs the service of the number of :that telephone terminal of the telephone network where he can currently be reached.
This number represents his personal number. The service is assigned a particular o•identification code within the telephone network. If another subscriber of the telephone network wants to set up a call to that subscriber, he will dial the identification code of this service. The call with the service identification code as the called number is recognized by one of the service switching points of the telephone S 25 network, which then triggers the service provided by the service control point for this call. The service control point then translates the called number in the call request to the subscriber's stored personal number, thus rerouting the call to the terminal addressed by the personal number.
An object of the invention is to provide a more convenient personal communications service to subscribers within a telephone network.
The applicant does not concede that the prior art discussed in the specification forms part of the common general knowledge in the art at the priority date of this application.
Summary of the invention According to a first aspect of the present invention there is provided a method of controlling the establishment of a call from a calling subscriber to a called subscriber through a telephone network, in which method a server of the telephone network is triggered for the call during call establishment and the triggered server then determines the called subscriber, accesses a personal user profile of the determined subscriber, which is stored in a storage unit, and controls the completion of the call in accordance with the personal user profile of the determined subscriber. The triggered server accesses a personal user profile of the determined subscriber which specifies, besides one or more terminals of the telephone network, one or more terminals of an IP network as terminals associated with this subscriber. The triggered server further determines status information about IP terminals specified in the personal user profile of the determined subscriber, and the triggered server controls the completion of the S0. call through the telephone network in accordance with the personal user profile of the determined subscriber and with the determined status information.
The invention further provides for a server for supporting the establishment of calls between calling subscribers and called subscribers through a telephone network, said server comprising a storage unit for storing personal user profiles of subscribers and a control unit designed in such a way that, when triggered for a call during the 25 establishment of this call through the telephone network, it determines the called *1 subscriber, accesses the personal user profile of the determined subscriber in the storage unit, and controls the completion of the call in accordance with the personal profile of the determined subscriber. The server further comprises a communication unit for receiving status information from terminals of an IP network, wherein in the storage unit, besides one or more terminals of the telephone network, one or more terminals of an IP network are specified as terminals associated with the determined subscriber, and wherein the control unit is further designed to determine status information about IP terminals specified in the personal user profile of the determined 3 subscriber and to control the completion of the call through the telephone network in accordance with the personal user profile of the determined subscriber and with the determined status information.
In a further aspect of the invention there is also provided a computer product for supporting the establishment of calls between calling subscribers and called subscribers through a telephone network, wherein the computer product is designed to carry out the above described method in conjunction with a computer platform of a server.
A preferred embodiment of the invention is based on the idea that in addition to terminals of the telephone network, the service takes into account terminals associated with the subscribers in a completely different communications network, namely IP terminals (IP Internet Protocol). The service additionally communicates with components of the IP network to which these IP terminals are connected, and thus determines information about the status of these IP terminals. A call is then switched through the telephone network in accordance with this determined status information.
.i :One advantage of a preferred embodiment of the invention is that it increases the 20 number of terminals alternatively addressable by the service, thus providing improved reachability. Furthermore, room is opened for a multitude of novel services that allow the call setup to be even better adapted to subscribers' needs.
Brief description of the drawings 25 The invention will become more apparent by reference to the following description of i several embodiments when taken in conjunection with the accompanying drawings, in which: Fig. 1 is a block diagram of a communications environment with several communications networks and with a server in accordance with the present invention; and Fig. 2 is a functional diagram of the server of Fig. 1.
Detailed description of the embodiments Fig. 1 shows three communications networks VNET, IPNET1, and IPNET2, two gateways GW1 and GW2, six terminals TEl to TE6, and a server SU.
Communications network VNET is a telephone network, such as an integrated services digital network (ISDN) or a public switched telephone network (PSTN). It may also be formed by two or more subnetworks, which may also be associated with different network operators. Such subnetworks may also be mobile radio networks, such as networks based on the GSM standard (GSM Global System for Mobile Communications). Terminals may thus be connected to communications network VNET via an analog PSTN line, an ISDN line, or an air interface according to the GSM or DECT standard (DECT Digital European Cordless Telecommunications).
Communications networks IPNET1 and IPNET2 are IP networks. Each of these communications networks is formed by a data network that uses an IP protocol as Layer 3. Examples of such an IP protocol are the Ipv4 or Ipv6 protocols.
Communications networks IPNET1 and IPNET2 are associated with different network operators or network access network operators, for example.
Terminals TEl, TE2, TE3, and TE6 are telephone terminals. Terminal TE6 is an ISDN terminal, terminal TEl is an analog telephone terminal, terminal TE2 is a mobile telephone based on the GSM standard, and terminal TE3 is a mobile telephone based on the DECT standard.
Terminals TE4 and TE5 are IP terminals, such as Internet-enabled telephones or a computer that is equipped with an interface card for communication over communications network IPNET2. They are preferably provided with VOIP software (VOIP Voice over IP), which enables a user to perform telephone communications over communications network IPNET2.
Terminal TE6 is associated with a subscriber B. Terminals TEl to TE5 are associated with a subscriber A.
The number of VOIP gateways GW 1 and GW2 has been chosen by way of example.
Gateway GW 1 interconnects communications network VNET and communications network IPNET and gateway GW2 interconnects communications network VNET and communications network IPNET2. Gateways GW1 and GW2 each provide interworking functions between a telephone network and an IP network.
Advantageously, each of gateways GW 1 and GW2 also provides the function of a VOIP gateway. Such VOIP gateways are gateways that allow a telephone call to be set up through IP networks. With the assistance of a gatekeeper, they perform address translation into an IP address, encoding/decoding, and packet assembly/disassembly of the data stream for transport through the IP network, as well as further functions, such as echo cancellation. Furthermore, they control the establishment of calls through the IP network. Such VOIP gateways may be implemented according to ITU-T Recommendation H.323, for example.
Server SU is formed by one or more interconnected processors, on top of which a software platform consisting of, an operating system and a database system is implemented. The software platform and the processors together Sform a computer platform SP. Together with a computer product CP, computer 20 platform SP performs the above-described functions of server SU.
Server SU may also be formed by one or more logic components running on a computer platform. In addition to the logic components forming server SU, logic components of other applications may, of course, be running on the computer 25 platform.
Computer product CP is formed by a data carrier and a computer program stored on this data carrier. If this computer program runs on computer platform SP, then server SoSSU executes the functions described below. Computer product CP may also be formed solely by this computer program as such.
Subscriber B, by means of his terminal TE6, initiates the establishment of a call to subscriber A through communications network VNET. During the establishment of 6 the call, server SU, which is associated with communications network VNET, is triggered for this call. Server SU then determines the associated called subscriber, i.e., subscriber A. Next, server SU accesses the personal user profile of subscriber A. In this personal user profile of subscriber A, the terminals associated with subscriber A, namely terminals TE1 to TE3 of telephone network VNET and terminals TE4 and of IP network IPNET2, are specified.
Then, server SU determines status information about IP terminals specified in this personal user profile of subscriber A, for example status information about the two terminals TE4 and TE5. To do this, server SU communicates with communications network IPNET2, to which terminals TE4 and TE5 are connected. Server SU then controls the completion of the call in accordance with the personal user profile of subscriber A and the status information.
Server SU may be formed by a service control point or be part of a service control point according to the IN architecture which provides services within telephone network VNET. Server SU may also form an integral part of an exchange of communications networks VNET.
a. S 20 If server SU is based on an IN architecture, a call may, for instance, be set up as follows. Subscriber B addresses subscriber A by a logical number assigned to subscriber A. If, during the establishment of a call, a service switching point of telephone network VNET recognizes such a logical number, which specifies the destination number of the call, it will send a service request message to the sevice control point that controls the service provided by server SU. In response to this service request message, server SU is then triggered for this call. Server SU then controls the completion of the call by sending control commands to the triggering service switching point or to service support systems (intelligent peripherals).
Particularly advantageously, server SU is implemented as part of a unit which provides a number portability (NP) service within telephone network VNET. Such an NP server must be triggered on each call establishment to determine the exact physical destination address of the call. If the destination address determined is a logical 7 number assigned to server SU, the NP server can trigger the server SU for the call directly.
The detailed structure of server SU and the sequence of steps in the method according to the invention will now be explained with reference to Fig. 2.
Fig. 2 shows server SU, which communicates with communication networks NVET, IPNET1 I, and IPNET2. From a functional point of view, server SU contains two communication units COM 1 and COM2, two control units CONTR 1 and CONTR2, and a storage unit UDB.
Communication unit COM 1 provides for communication with components of communications network VNET. Such components are preferably service switching points of communications network VNET. In particular, communication unit COM 1 provides functions for processing the protocol stacks necessary for this communication.
Communication preferably takes place via the signaling system of communications network VNET. Communication unit COM1 thus comprises functions for processing 20 the protocol stack of Signaling System No. 7 and of the INAP protocol (INAP Intelligent Network Application Part).
The INAP protocol may also be transported via an IP protocol stack. Communication may also take place between components of communications network VNET and 25 server SU, namely via a software bus, for example in accordance with the Common Object Request Broker Architecture (CORBA), so that the INAP protocol is not necessary.
Communication unit COM2 provides for communication with components of communications networks IPNETI1 and IPNET2. Such components are preferably servers or terminals of these IP networks. In particular, communication unit COM2 provides functions for processing the protocol stacks necessary for the reception of status information from terminals of these IP networks: For the Layer 3 protocol, the 8 IP protocol is used, and for the Layer 2 protocol, an ATM protocol (ATM Asynchronous Transfer Mode) or a LAN protocol (LAN local area network), for example, is used.
Storage unit UDB serves to store personal user profiles of subscribers. It is formed by a database. For each subscriber to whom server SU provides a service, such a personal user profile is stored in storage unit UDB. Each of these user profiles specifies one or more terminals that are associated with the respective subscriber. Besides one or more terminals of the telephone network, it is possible to specify in the storage unit one or more terminals of an IP network as the terminals associated with the respective subscriber. In addition to these terminals associated with the respective subscriber, the user profile comprises further parameters. These parameters contain the following information, for example: They define an order of priority of the terminals, contain instructions regarding what to do in response to status information about terminals, contain recorded announcements to be sent to calling subscribers, contain further information that describes the subscriber, or contain passwords that permit access to and modifications in the user profile.
A possible data structure of a user profile will now be illustrated by the example of the 20 data structure of the user profile of subscriber A.
The data structure includes the logical number of subscriber A, by which the latter is addressed in a call. The user profile of subscriber A is addressed with this logical number within storage unit UDB. The data structure further includes the logical and/or 25 physical addresses of terminals TE 1 to TE5, for example the directory numbers of terminals TE1 to TE3, which address these terminals within communications network VNET, and the IP addresses of terminals TE4 and TE5, which address these terminals within communications network IPNET2. In addition, the data structure includes an identification code for the communications network to which the respective terminal is connected, for terminals TEl to TE3 an identification code for communications network VNET or the respective subnetworks thereof to which these terminals are connected. For terminals TE4 and TE5, the data structure includes an identification code for communications network IPNET2. The user profile further includes a set of parameters which, on the one hand, define an order of priority of terminals TEl to and, on the other hand, specify for each of the terminals how to proceed with which status information about the respective terminal.
Storage unit UDB may also form an integral part of a number portability database.
During the establishment of a call through the telephone network, control unit CONTR1 is triggered for this call by the reception of a specific service request message via communication unit COM1, for example. When triggered for a call, control unit CONTR1 performs the following functions for this call: First it determines the called subscriber associated with this call. For this purpose, it receives via communication unit COM1, for example, the logical number to which the call is addressed, and, using this logical number, searches storage unit UDB to determine the subscriber's user profile, and thus the subscriber himself.
The control unit then accesses the subscriber's personal user profile stored in storage unit UDB. It reads parameters of the user profile and addresses of terminals that are specified in the user profile as terminals associated with the subscriber.
S Next, control unit CONTR1, by accessing communication unit COM2, determines status information about IP terminals specified in the personal user profile of the determined subscriber. Status information is information about the condition of the IP terminal, for instance whether the IP terminal is currently connected to the IP network 25 (on-line/off-line), whether the IP terminal is currently communicating with other terminals or with servers of the IP network, or information about the amount of communication or processing resources the IP terminal currently has available for its use.
9 9 Control unit CONTR1 obtains those status data by polling those IP terminals, or servers of the respective IP network that are associated with those IP terminals, via communication unit COM2. To do this, the communication unit sets up a connection to the IP network the respective IP terminal is associated with. The communication thus takes place during the establishment of the telephone connection. It is also possible, however, that the terminals or a server of the IP network send the status information to server SU on their own. In that case, the communication would preferably take place at the beginning of the IP session of the IP terminal or on a modification in the status data.
Control unit CONTR1 then controls the completion of the call in accordance with the determined subscriber's personal user profile and with the determined status information. Depending on the instructions in the parameter data of the user profile and on the status information determined, the control unit will initiate the completion of the call to one of the terminals specified in the user profile, abort the call establishment, or cause a message text or a recorded announcement to be sent to the calling subscriber.
It is also possible that control unit CONTR 1 sends an incoming call indication message via communication unit COM2 to an IP terminal specified in the subscriber's personal user profile. The sending of this message may be dependent on the instructions in the parameter data of the user profile.
Furthermore, it is possible that control unit CONTR1 additionally controls the ••completion of the call in accordance with a message that an IP terminal specified in the subscriber's personal user profile sends via communication unit COM2 to control •go unit CONTR1. This message may preferably be a response to a message sent to this IP terminal by control unit CONTR1 which indicates to the latter an incoming call.
Advantageously, control unit CONTR 1 controls the establishment of a VOIP call to an IP terminal specified in the determined subscriber's personal user profile when it determines on the basis of the parameter data and the status data that thecall is to be established to this IP terminal. The fact that a VOIP call is to be established may also be specified as an additional instruction in the parameter data. Such a VOIP call is set up by initiating the establishment of a connection to a VOP gateway and transferring the address of the IP terminal to this VOIP gateway.
11 Control unit CONTR2 serves to enable subscribers to modify and read their personal user profiles from communications networks IPNET1 and IPNET2. To accomplish this, control unit CONTR2 interacts with communication unit COM2 and storage unit UDB. The subscribers can thus access these data via an IP terminal. Advantageously, personal user profiles can only be modified by an IP terminal specified in the personal user profile. It is also advantageous to provide access control using passwords that are stored in the subscriber's personal user profile.
