Definitions
- the present invention relates to a method for charging a communication connection between a first communication terminal of a first packet-switched communication network and a second communication terminal of a second packet-switched communication network.
- the case is particularly interesting if the first 5 packet-switched communication network is the Internet.
- communication devices such as laptops, computers, PDAs or mobile phones, are connected to the Internet using various technologies, such as telephone dialing, leased line or satellite connection.
- GPRS General Packet Radio Service
- UMTS Universal Mobile Telecommunications Service
- various information will be directed from the Internet to such 5 communication terminals in the future.
- the operators of the mobile radio networks will require payment for the use of mobile radio resources, for example in the form of communication fees.
- a method for charging a communication link between communication terminals connected to the Internet and mobile target communication terminals is already known from European application EP 02090124.
- the exact loading action of the individual packets to be transported in such a communication connection remains open.
- a communication link between two different packet-switched communication networks is always packet-oriented.
- the communication networks can be, for example, mobile, packet-oriented mobile radio networks, or one of the two can also be the Internet. Since a communication connection is not circuit-switched, but rather packet-oriented, a transition node between the two networks has no control over a continuous transaction in or from one of the two directions, but each individual packet being transported must be assessed separately. In order to detect packets for charging the communication connection, the problem arises of having to identify each packet passing the transition node with regard to its origin, that is to say from which direction or from which packet-switched communication network the packet comes.
- An object of the present invention was to provide a method with which communication connections between communication terminals of a first packet-switched communication network and communication terminals of a second packet-switched communication network can be identified and billed accordingly in a secure and reliable manner.
- a method for charging a communication connection which is established between a first communication terminal of a first packet-switched communication network and a second communication terminal of a second packet-switched communication network, is provided, in which a set-up request message relating to the communication connection is sent from the first communication terminal or from the second communication terminal is routed to a transition node between the first and the second communication network, the setup request message is forwarded from the transition node to an evaluation and control unit, the evaluation and control unit evaluates the setup request message with regard to its origin and determines in a rule whether the communication connection in question is to be set up is billed or is treated as free of charge. The charge is made accordingly via a fee calculator.
- the evaluation and control unit has a functionality which receives the assembly request message and can evaluate it with regard to the direction from which the message comes, that is, its origin. With the help of the direction from which the setup request message comes, .sich., The ..initiator, of the communication connection can be determined. Based on the knowledge of the initiator of the communication connection, the evaluation and control unit now defines a rule as to whether the communication connection in question is charged or treated as free of charge. In a particularly preferred embodiment of the method according to the invention, the evaluation and control unit forwards the specified rule to all transition nodes which are involved in the detection of the packets to be transported for the relevant communication connection. The packets are ignored by the transition nodes if the communication link in question is treated as free of charge in accordance with the rule. If, on the other hand, the communication connection is billed in accordance with the rule, the packets are captured by the transition nodes and a corresponding charge is made via the fee calculator.
- the Internet is preferably used as the first communication network. This means that a communication link _. is established between a communication terminal connected to the Internet and a second communication terminal of a packet-switched communication network.
- a packet-oriented mobile radio network is particularly preferably used as the second communication network. This scenario is particularly interesting because with the advancing development of third generation mobile networks more and more information is being transmitted from communication terminals connected to the Internet to target communication terminals connected to cellular networks.
- the target communication terminals can be, for example, cell phones, laptops or PDAs with a cell phone interface.
- Communication terminals connected to the Internet can be, for example, computers, laptops, PDAs or mobile telephones which are connected to the Internet using various technologies, such as, for example, a telephone dial-up connection, dedicated line or satellite connection.
- the first communication terminal which is connected to the Internet
- communication terminals that are not directly connected to the public Internet can also be used, but in which access to the internet takes place via one or more intermediate access networks.
- the communication connection between the first communication terminal and the second communication terminal can also be established via the Internet.
- the Internet only functions as a transitional network.
- the transition node represents a connection node connecting the Internet to the mobile radio network.
- the connection node (gateway) accordingly represents a type of “input node ⁇ or“ first Node * of the mobile radio network. It is particularly advantageous here that the connection the connection request message to the evaluation and control unit for evaluating and establishing a rule relating to charging is initiated at a point in time when a connection between the networks is established for the first time, that is to say at the very beginning of the establishment of a communication connection between the networks. From the start of the establishment of the communication connection, this clarifies how the packages of the communication connection to be transported are to be treated in terms of fees.
- an element of a data packet control system that controls the connection setup is used as the transition node.
- the evaluation and control unit is integrated in a transition node. This has the advantage that no new unit has to be generated, but rather only an additional radio
- the second communication network is a mobile radio network
- a network computer of the mobile radio network is preferably used as the charge calculator.
- Such 25 mode of the invention is par- - ⁇ • dere- advantageous because .the. Communication takes place between the transition node and the network computer of the cellular network within the cellular network. This enables a particularly secure or tap-protected data transmission, which on the one hand takes into account the high security requirements in charging procedures and on the other hand guarantees data protection in a particularly good manner.
- the network computer can, for example, be arranged in the data control system.
- an Internet computer of the Internet can also be used as the fee calculator.
- an Internet computer available on the Internet as a fee calculator.
- the services of a service provider of the Internet can be used for this.
- the method can be implemented more cost-effectively than when a separate fee calculator is installed.
- the rule set up by the evaluation and control unit is stored in the transition node after it has been forwarded to all the transition nodes which are involved in the detection of the packets to be transported for the communication link in question.
- the transition nodes throughout the duration of the 'communication connection informed is done with the case parcels transported to.
- a one-time forwarding of the rule set up by the evaluation and control unit to all transition nodes is sufficient to determine the charging of the entire communication link. This is very efficient and therefore inexpensive.
- the transition nodes know the initiator of the communication link and the associated billing determined by the rule.
- the rule is made up of general and connection-related parts.
- an end message is sent to terminate the connection of one of the communication terminals, which is evaluated by the evaluation and control unit.
- the rule is then removed.
- the evaluation and control unit sends a message to all affected transition nodes, which indicates that the rule is invalid.
- all packets between the communication terminals of the previous communication connection are no longer treated in accordance with the previous rule.
- an interface is provided between the evaluation and control unit and the fee calculator.
- the evaluation and control unit can thus inform the fee calculator directly about the fee regulation. This is much more efficient than indirect information about one or more transition nodes.
- FIG. 1 shows a schematic representation of an embodiment of a sequence of the method according to the invention
- a communication terminal KEG1 is shown on the right in FIG. It can be, for example, a computer.
- This communication terminal KEG1 is connected to the Internet INET via an Internet access network. No details are shown from the Internet itself. Of course, there are a large number of switching computers on the Internet and to these switching computers closed internet computers.
- two transition nodes (gateway) GW1 and GW2 are shown.
- One of the transition nodes, here GW1 is connected to an evaluation and control unit RBF (rule-determination function).
- the evaluation and control unit RBF is also connected via an interface to a fee calculator GS.
- Both transition nodes GW1 and GW2 are also connected to the fee calculator GS.
- the transition nodes GW1 and GW2 are also connected to a mobile radio network MFN.
- IMS IP Multimedia Subsystem
- IP Internet Protocol
- the IMS data packet control system is connected to a GPRS data transmission system.
- GPRS General Packet Radio System
- a second communication terminal KEG2 is shown connected to the mobile radio network MFN; in this case it is a mobile phone.
- a data packet control system IMS is generally used for packet-based multimedia control for mobile communication networks.
- the IMS control system makes it possible to provide multimedia services both for the mobile access networks and for the Internet.
- the control functions are carried out using a protocol called “Session Initiation .Protocol ⁇ , (SIP).
- SIP Session Initiation .Protocol ⁇ ,
- This generic protocol can be used both to control the connection establishment of participants within the mobile radio network and the connection establishment between participants in the mobile radio network and participants in the Internet.
- the connections are controlled via a so-called “Call State Control Func- tion * (CSCF), which is a component of the control system
- a communication link KV is now to be set up between the two communication terminals KEG1 and KEG2.
- a communication request message AF is now sent by this communication terminal.
- the communication terminal KEG1 initiates a communication connection via the Internet INET and accordingly sends a setup request message AF via the gateway GW1 to the mobile radio network MFN or via the data control system IMS of the mobile radio network to the data transmission system GPRS.
- the assembly request message AF therefore first arrives at the gateway GW1.
- the initiator of the communication link KV can only be determined on the basis of the direction from which the assembly request message AF comes.
- the assembly request message AF is sent to the evaluation and control unit RBF according to the invention.
- the setup request message AF contains information about the communication link to be set up KV and about the communication participants KEG1 and KEG2, which are characterized by corresponding IP addresses.
- the evaluation and control unit RBF now uses the information contained in the. Assembly request message AF are included for the communication link KV to be set up, how to deal with the packets of this communication link KV. This means that the RBF determines whether the packages are to be recorded for charging by the GW1 or GW2 or not.
- the RBF can stipulate that in the event that the communication link KV is initiated by the Internet subscriber KEG1, all packets of this Communication link KV through the gateways to be detected; in the event that the communication link KV has been initiated by the mobile telephone KEG2, the packets of this communication link KV are ignored by the gateways.
- the rule is distributed by the evaluation and control unit RBF to all gateways involved in the communication connection, here to GW1 and GW2.
- the address of the GW1 of the evaluation and control unit RBF is known, since the assembly request message AF was sent to the evaluation and control unit RBF.
- the evaluation and control unit RBF can determine the address of the second gateway GW2 from the IP address of the mobile telephone, which is transmitted to the evaluation and control unit RBF with a response message AN from the mobile telephone. After receiving the rule, this rule is saved by the gateways.
- To end the communication link KV one of the two communication terminals KEG1 or KEG2 or the corresponding subscriber will send an end message EN. This end message EN is evaluated by the evaluation and control unit RBF.
- the evaluation and control unit RBF then sends an indication to the gateways GW1 and GW2 which indicates that the rule is invalid.
- the two gateways GW1 and GW2 then ignore all packets of the communication connection KV. Which was previously established between the IP addresses of the communication terminals KEG1 and KEG2.
- the evaluation and control unit RBF has an interface with the fee calculator GS. Furthermore, to reduce the complexity, it can be useful to route the entire traffic of a communication link KV via exactly one gateway.
- the evaluation and control unit RBF can, for example, the address of the first gateway GW1 in the header of the assembly request message Set AF and thus require the communication network to route all packets via the first gateway GW1.
