Definitions
- the invention relates to an integrated control unit according to the preamble of patent claim 1.
- adaptation units For the mutual exchange of information between packet-oriented networks with different transmission protocols, adaptation units are known, which are also referred to in the technical field as an 'interworking unit'.
- transmission protocol is used in the following for communication protocols between terminals arranged in the packet-oriented network above a transport or connection level.
- Such a transmission protocol is designed, for example, in accordance with the known 'H.323' or 'SIP' standards.
- SIP Session Initiation Protocol
- IETF Internet Engineering Task Force
- the H.323 standard is an international ITU-T standard (International Telecommunication Union - Telecommunication Standardization Sector) for voice, data and video communication over packet-oriented networks, which ensures interoperability of the manufacturer's products with one another.
- ITU-T International Telecommunication Union - Telecommunication Standardization Sector
- a communication computer unit is arranged in each of these packet-oriented networks, also referred to in the technical field as 'protocol server'.
- a log server has a network-side interface that is used to exchange packet-oriented data for end devices and / or protocol servers of the same protocol type.
- the said adaptation unit - interworking unit - is used to convert messages from a first packet-oriented network to a second packet-oriented network that has a different transmission protocol.
- the adaptation unit is arranged between the first and second networks. Due to this form of connection, the adaptation unit is also called 'gateway' in the professional world. There are both protocol and signaling gateways.
- a gateway is a hardware and / or
- Protocol servers and the respective network is arranged.
- FIG. 2 The prior art is illustrated below with the aid of the drawing, FIG. 2.
- FIG. 2 shows a first network DM1, which exchanges data with a second network DM2 via an adaptation unit IWU.
- the first or second network DM1, DM2 is a respective first or second database '
- the two databases DB1, DB2 can be synchronized with one another via synchronization means (not shown) using synchronization information SYNC.
- the adapter unit IWU connecting the two networks DM1, DM2 is connected to the first network DM1 via this network DM1 assigned first protocol server GK connected.
- this first protocol server GK is also called 'gatekeeper'. 5
- the adaptation unit IWU is connected to the second network DM2 via a second protocol server PRX.
- the second protocol server PRX assigned to the second network DM2 is also called 'proxy' in the terminology of the SIP standard.
- infrastructure means IST are arranged, which are present, for example, in the form of distributed computer units, network means, mass storage means, etc.
- 35 le certain applications APP or services SVC are limited to the first network DM1, since corresponding control messages calling these services SVC or applications APP cannot be translated into the second network DM2 by the adaptation unit IWU. For this reason, corresponding applications APP and services SVC must be implemented separately in the second network DM2 with regard to the transmission protocol used there and with a different scope of functions.
- L5 adaptation unit IWU communicating with the respective gateways GK, PRX is not provided. This often results in redundant storage or maintenance of the data in the respective database DB1, DB2, with synchronization of the data exclusively with proprietary and frequently error-prone
- the protocol servers GK, PRX communicating with the adaptation unit IWU each act as the end point of a communication connection and provide evidence for this communication task
- This communication connection results in a consumption of resources, above all in the occupancy of a logical communication interface, also called 'port' in the professional world.
- Data transmission via the respective protocol server
- PRX mainly takes place via so-called reserved ports, also known as 'well-defined ports' in the professional world.
- reserved ports also known as 'well-defined ports' in the professional world.
- the communication protocol unit (not shown) containing the respective protocol server GK, PRX is no longer possible for further applications of these well-defined ports.
- the protocol server PRX ('SIP Proxy') and the adaptation unit IWU ('Gateway') are implemented on this - not shown - the 5 infrastructure means IST of the second communication network DM2 assigned - communication computer unit not technically feasible.
- Another aspect of a disadvantageous resource allocation is that for an application APP initiated by the first network DM1 and to be executed in the second network DM2, a large number of control or confirmation messages must be exchanged, the messages in and between the packet-oriented networks DM1, DM2 exchanged data packets L5 cause a high occupancy of transmission means in the networks DM1, DM2.
- data packets are always transported with a network-dependent delay, which additionally slows down the execution of services SVC or applications APP in the other network DM2, DM1.
- the object of the invention is to provide means in whose applications the above problems are avoided.
- an integrated control unit with modular gateway modules and with protocol-independent application and service modules controls terminal devices in several networks that support different transmission protocols.
- Control and signaling data are controlled in the modular gateway modules under the control of an expansion module controller via the gateway. exchanging data, ie data packets encoded in a corresponding transmission protocol.
- a particular advantage of the control unit according to the invention is the integration of the protocol-independent gateway module in a host computer environment, on which applications and services are also available. This enables defined application interfaces, which make it easy to add other modular, protocol-independent gateway devices.
- the integrated solution eliminates special devices in the respective network, e.g. a route determination - also called routing in the professional world - or protocol implementation mechanisms between the connected networks.
- control unit according to the invention is that there is no synchronization of control and signaling messages exchanged between network-external applications or services, since all operations within the computer system of the control unit have a defined processing time - often also referred to as 'real-time processing' - be carried out.
- a database arranged in the control device for storing and retrieving data of the applications and services makes the provision and maintenance of databases assigned to the individual networks superfluous.
- Another advantage is the simple maintenance of the data contained in this database, which do not have to be synchronized between two networks.
- FIG. 1 a structural diagram for the schematic representation of a connection of networks to a control unit
- FIG. 3 a structural diagram for the schematic representation of functional units of the control unit.
- FIG. 1 shows a control unit ICG with a first, a second and a third gateway module GW1, GW2, GW3.
- the gateway modules GW1, GW2, GW3 are connected to a respective network DM1, DM2, DM3.
- the networks DM1, DM2, DM3 are not necessarily topologically and physically separate networks DM1, DM2, DM3. Rather, a separation of these networks DM1, DM2, DM3 serves to illustrate the picture and is therefore not to be understood physically.
- the networks DM1, DM2, DM3 are rather to be understood as different 'logical' networks DM1, DM2, DM3 with mutually identical communication protocols in an otherwise common network with heterogeneous communication protocols.
- the gateway modules GW1, GW2, GW3 each exchange data with infrastructure means IST within the control unit ICG, which are available, for example, in the form of distributed computer units, network means, mass storage devices, etc. With the aid of these infrastructure means IST, services SVC or applications APP are implemented within the control unit ICG.
- An example of a service SVC is, for example, an 'instant messaging service' which carries out a transmission of text messages.
- SVC Session Initiation Protocol
- An example of a service SVC is, for example, an 'instant messaging service' which carries out a transmission of text messages.
- call data acquisition is necessary, which is an example of an executable application APP.
- Data to be stored via the infrastructure means IST are stored in a central database DB arranged within the control unit ICG.
- Versions relating to network DM1 apply analogously to the second network DM2.
- control unit ICG shown as a system unit in the exemplary embodiment can also be implemented with distributed system components, using known technologies for communication in distributed systems such as, for example, 'Corba' (Common Object Request Broker Architecture), or the Microsoft 'COM' (Component Object Model) or '.Net' technologies.
- each gateway module GW1, GW2, GW3 can also be implemented as an independent computing unit; the database DB can also be implemented on a mass storage device connected via a network (not shown).
- control unit according to FIG. 3 is explained in more detail below with further reference to functional units of FIG. 1.
- FIG. 3 shows software and / or hardware units of the integrated control unit ICG, which are designed in a modular architecture.
- the connection method of the integrated control Unit ICG to the networks DM1, DM2, DM3 is identical to the description above.
- FIG. 3 shows the individual functional components of the integrated communication unit ICG.
- This comprises a protocol server based on the SIP transmission protocol, the first gateway module GW1, shown in dash-dot lines, consisting of a protocol module PRM, a state machine SM, a static routing module SR, an expansion module controller EMM and a domain name determination service module DNS.
- Further components of the integrated communication unit ICG correspond to the components described in FIG. 1, namely the second or third gateway module GW2, GW3 and the database DB, the application module APP and the service module SVC.
- the interface to the first network DM1 is formed by a functional unit Winsock WSO.
- the term 'Winsock' denotes a logical interface for IP implementations ('Internet Protocol') of the 'Windows' operating system family from Microsoft Corp.
- the Internet Protocol is used on a transport level to transmit the data packets in the first network DM1.
- the transmission protocol SIP lying in the first network is in principle independent of the transport protocol used.
- the Winsock WSO extracts from incoming data packets - cf. 3 in the left-hand area of FIG. 3 - a piece of useful information and transfers it in the form of so-called datagrams to the (SIP) protocol module PRM.
- the protocol module PRM uses the parser module PRS to assign text information contained in the SIP datagrams to logical commands or status information or status information, which are transferred to the state machine SM - also called 'state machine' in the technical field.
- the state machine communicates information with the expansion module controller EMM using the so-called 'static routing' module SR.
- This static routing module SR defines processing sequences which are subject to a fixed sequence, for example an interaction of the form 'request-confirmation-data transmission'.
- the EMM expansion module controller coordinates the transmission of data packets and transfers them - cf. Down arrow in the right area of Fig. 3 - corresponding information to the protocol module PRM. Such transmission processes may also be carried out with a flow definition with the participation of the static routing module SR.
- the data packet may be transferred to the domain name determination service module DNS.
- Domain name discovery services are also referred to in the professional world as 'DNS Query' (Domain Name Service).
- a transmission module TM arranged in the protocol module finally generates a SIP datagram to be sent from the information transmitted and transfers it to the Winsock WSO, which encapsulates the SIP datagram in a data packet and sends it to the first network DM1.
- the expansion module controller EMM communicates with the aforementioned functional units and coordinates the implementation of the data to be exchanged when services or applications are executed in the respective network DM1, DM2, DM3 through the gateway module assigned to the respective network DM1, DM2, DM3 GW1, GW2, GW3.
