Abstract

The present invention relates to a system comprising a managing system (10) and a number of managed systems (11A, 11B;12A, 12B, 12C;13A), each comprising a number of managed objects, which managed systems are managed by said managing system (10). Via a number of mediating managed systems (11, 12, 13) the managing system sends management operations addressing managed objects on a management interface (15). Management operations addressing managed objects not recognized, or not administrated, by the receiving mediating managed system are routed to another mediating managed system. The invention also relates to a mediating managed system including a routing functionality.

Description

ARRANGEMENT, SYSTEM AND METHOD OF COMMUNICATION ADMINISTRATION FIELD OF THE INVENTION The present invention relates to a system comprising at least one management system that manages several managed systems, comprising managed objects that represent resources, through several managed systems of mediation. A management interface provides communication between the management systems and the managed systems and management operations focused on managed objects are sent in said management interface. The invention also relates to an arrangement such as, for example, a managed mediation system for the administration of a number of resources represented by managed objects and to which management operations are sent through a management interface. Furthermore, the invention relates to a method for carrying out an operation on one or more objects handled in a managed system that is handled by a management system that sends a handling operation in a management interface that provides communication between a system of operation. management and several systems managed. STATE OF THE ART The management, for example, of telecommunications networks is an area that requires increasing attention, among other reasons because the number of mobile telecommunication systems that exist that are based on different standards, different technologies, etc., it increases day after day. In addition, there is a continuous increase in the number of services provided and in development and services are becoming increasingly complex and advanced. Since there is also a significant number of different sellers of similar or different products and a significant number of different operators, there are many players in the market. Frequently, specialized products are required adapted to each specific system, even if the products as such support the same functionality, etc. An example is in the area of service management for mobile communication networks, such as GSM (Grupe Spéciale Mobile), PCS (Personal Communication System), PCN (Personal Co munication Network). ) (Personal Communication Network), etc. since telecommunication networks are becoming increasingly larger as mentioned earlier, several different management systems, in this context operating systems, are used to control the networks and equipment of different vendors, and services in the Networks are controlled in different ways which makes the operation and maintenance costly and complicated. Therefore, the concept of telecommunications management network (TML) has been defined. This is described in the ITU-T recommendation M.3010. According to the TMN, the telecommunications network is considered as operations systems in a standardized interface where all types of network equipment can be monitored and controlled in a similar way. An example in an operations system is a management system, such as a CAS system (Customer Administration System). A system of operations or particularly a client management system operates on several network elements in one interface. Particularly to provide subscription, a device is often offered that formulates a set of rules to present a uniform interface to the client management system, the interface is known as a client management interface, such as CAI which is similar to CMISE and it is based on the GSM standard. A device of this type comprising a managed mediation system, or a mediation device, as is known within the TML concept, is helpful in many respects. It is easy to integrate with existing computer platforms. A known device employs communication standards such as TCP / IP and X.25. TCP / IP means Transmission Communications Protocol / Internet Protocol (transmission communication protocol / Internet protocol). A multi-session interface is known - a message, a response per channel that supports service interface management services (CMISE) services, therefore supporting actions such as the creation, adjustment of a value, obtaining a value and removing a value, a managed object, performing an action in a managed object, requesting a managed object to carry out an action, etc., and also using filtering and scope evaluations to establish which managed objects are involved, etc., is also described, for example, in ITU-T, Recommendation M.3010, ITU-T, recommendation X.710, etc. In managed systems, here network elements, several managed objects (OMS) that represent resources form the management approach for the operating system here CAS, and the physical location of the data, that is, the resources represented by the managed objects. , it is hidden for the CAS by the mediation device. A mediation device of this particular type is known, however, it is a GSM-specific product and does not support any other mobile communication standard. In addition, flexibility is limited insofar as it does not support several devices, such as mobile intelligent network services. Even if the mediation device shows in other aspects a high degree of flexibility, including multiple sessions where the operating system here CAS, does not have to be informed as to which physical server is in a channel but only one address, the The number of channels to CAS from a performance perspective depends on the number of connections available for the network elements handled and the capacity of extension and increase of the device is limited. A solution to some of these problems would be to copy the interface into other products but it suffers from at least one major drawback, since it would require the administration system or more generally, the operating system (OS) to know which mediation device it manages which managed systems (or what network element) and also what network element functions (from TMN known as NEF). If the network is complex, if it includes for example different services and different mobile standards, it would be extremely complicated for the administration system to provide an integration towards existing managed systems or particularly network elements. Even worse, if a load sharing is applied by using more than a mediation system, the solution would be even more complex. Thus, what is really required, would be to provide market adaptations for each client. In this way, most problems would persist, the development of the products would be expensive and the use would be inflexible. COMPENDIUM OF THE INVENTION What is required is therefore a system comprising a management system that manages several managed systems where several managed objects represent a number of resources, the managed objects form the management view to the operating system, through various managed mediation systems in a management interface that provides communication between the management system and the managed systems, or a managed mediation system, where management operations directed to managed objects are sent in the management interface, through which the management operations directed to managed objects can be carried out regardless of whether or not the managed objects are really included in the managed system that is managed or managed by a managed mediation system, receiving the operation of simple way and without requiring the management system to be aware of what managed objects are managed by which managed mediation system. It also requires a system that allows a high degree of flexibility and through which different standard systems or networks can be handled in an easy way., including high performance, high extension capacity and increase, where managed systems of mediation or, more generally, arrangements that receive operations, can be easily added in a simple manner, in a profitable manner without affecting other managed mediation systems that act as reception arrangements for handling operations. In particular, the other managed mediation systems are provided only with information in the sense that a new managed mediation system or new functionality has been added.; in particular, they do not have to be informed that another functionality has been introduced in such a way that another system can be handled by the management system. It also requires a system through which a management system, or particularly a system of operations, does not have to be aware of which managed mediation system manages what systems managed or what system functionality is handled. A managed mediation system that acts as a reception arrangement for handling operations is also required through which the aforementioned objects can be achieved. In addition, a method is required to carry out an operation on several objects managed in a managed system, which is handled by a management system that sends a handling operation in a management interface that provides communication between management systems and systems. managed, through which the operation can be carried out in the managed managed objects, regardless of whether or not the managed objects are in fact handled or administered by a managed mediation system that receives the operation of operation, in a simple manner and that without the management system having to know which managed mediation systems, ie, reception arrangements, manage or manage the managed objects in focus and where the management interface not only supports communication between a management system and a managed mediation system , or a managed system, but also supports a communication between several managed systems of mediation . In accordance with the present invention, a management operation received in a managed mediation system (or a managed system comprising a mediation functionality) that focuses on one or more managed objects that are not recognized or managed by the managed system. reception mediation (or the managed system that includes a mediation functionality) is routed to at least other managed mediation systems (or a managed system that includes mediation functionality). This routing is carried out in different ways. In accordance with one modality, the routing from a managed mediation system (or managed system that includes a mediation functionality) will then be known only as a managed mediation system even though it can also be a managed system that includes said mediation. functionality) towards a managed system of neighbor mediation, or some other managed mediation system with which the managed mediation system of reception communicates through the management interface, consecutively until a managed mediation system is in which recognizes the managed objects to which the operation is focused, or which manages the managed objects in focus. In one modality, the routing is carried out in any order until finding the managed system of mediation sought. In an alternative mode, the routing is carried out in a controlled manner. In the latter case, the managed system of reception mediation maintains information as to which managed mediation systems manage which objects are handled, in such a way that the operation can be routed to said managed system of mediation, either directly or through of a given route. In another modality, only some of the managed mediation systems retain information as to which managed objects are administered or managed by a given managed mediation system, in this case, the operation is directed, for example, to the managed system of neighboring mediation. until such a managed mediation system is found, which then routes the operation in a controlled manner. In particular, a managed mediation system manages several managed objects, or manages one or more managed systems, and / or one or more function blocks, within a number of managed systems. In addition, particularly a management system is not aware of which managed mediation system is sent and / or routes a handling operation. In a particular modality, each managed system of mediation provides access (by the management systems) to all the functionalities, or to any managed object, supported by all the managed systems. As mentioned above, a managed mediation system keeps at least information as to which managed objects are included in the managed mediation system itself, and the managed objects included in managed systems managed by said managed mediation system. However, as mentioned above, a managed mediation system may also retain information as to which managed mediation system it manages, or comprises, some or all of the other managed objects of the system. One or more managed mediation systems may receive instructions to reject unrecognized operations. If no managed mediation system is found that recognizes the Mos focused by the operation, the operation may also be rejected. Each handled object receives a name that distinguishes it, that unique within the system, and at least one case name that is unique within the managed system to which it belongs, or in which it is understood, as a representation of the resources of the managed system . The distinguished name includes the case name and the name, or the address of the managed system. Each managed mediation system comprises a detection and routing function, hereinafter referred to as a distinguished name function (DNF), and to find the address of a managed system, it is used in the case name within this managed system.

In a profitable modality, the routing functions (DNF) of all managed mediation systems retain information regarding all managed objects or all cases of managed objects in the system. The information must then be conserved consistently throughout the system, that is, conserved consistently within all mediation systems. Particularly, the information here refers to information regarding the "location" of the object case handled, according to a modality, if an operation is focused on a managed object that can not be identified by the managed system of reception mediation. , the management operation is rejected and returned to the delivery system, which, if it is a management system, includes the transmission of a warning In a useful modality, a new system or an additional managed mediation system can be added to the system without requiring of any change or authorization of the other managed mediation systems, however, advantageously, the other managed mediation systems or some of the other managed mediation systems are equipped with information in the sense that a managed system has been added However, if all the mediated mediation systems retain information regarding all or managed objects of the system, are equipped with said information for example to allow a controlled routing to said new managed mediation system. Particularly, each managed mediation system comprises an agent, for example, for each of several types of managed objects that are managed or managed by said mediated managed system, through which the handled objects are handled by the management system. In particular, there is an agent for each type of object handled. Several managed mediation systems can be arranged in the same hierarchical layer, but managed mediation systems can also be arranged in different hierarchical layers. For example, a mediated managed system can be a mediated managed system superior to a number of subordinated managed systems and vice versa. In a more profitable modality, the routing function supports at least two routing alternatives, such as a primary and a secondary route, to another managed mediation system, or to several other managed mediation systems, in order to offer redundant paths in the case of a link failure or in the case of any other type of malfunction. Advantageously, a shared burden is also provided between the managed mediation systems. This is provided through a routing function (DNF) that not only recognizes the types of objects handled but also allows case information regarding managed objects to be used in combination with object type information handled for the selection of an object. appropriate agent. In a useful modality, the system refers to a telecommunications management network (TMN), where the management system or management systems comprise (n) operating systems (OS), the managed systems comprise network elements (NE ), and managed mediation systems comprise mediation devices (MD). A mediation device may comprise either a network element or it may be used as a network element protocol. In a useful mode, the management interface supports common management information service elements, ie, common management information services (CMISE). CMISE is discussed in ITU-T (formerly CCITT) recommendation X.710, which is incorporated herein by reference. Each mediation device comprises an agent for detecting and routing functionality. In a useful manner, it also comprises agents for one or more network elements or types of handled objects. Examples of network elements are the home location register (HLR), mobile switching center (MSC), equipment identity record (EIR), authentication center (UC), etc. However, it should be clarified that these are only examples provided for reasons of exemplification. In a useful embodiment, the system comprises dedicated mediation devices for several different telecommunications systems, such as devices for one or more of the following: GSM, NMT, ADC, PDC, DECT, D- (AMPS) etc. In a useful modality, the management system, or the operating system, is a management system, such as a customer management system (CAS) and the management interface comprises a customer administration interface (CAS). which includes the extended functionality that provides an intercommunication between mediation devices. A managed mediation system is therefore also provided to manage various resources represented by managed objects to which handling operations are sent in a management interface. The managed mediation system comprises a function to route incoming management operations focusing on unknown managed objects or not managed by said managed mediation system to another managed mediation system. The managed mediation system functions as the mediation managed systems described above with reference to the system including, among others, said managed mediation system and includes any of the functionalities described above. Advantageously, the routing function comprises at least one table of handled objects comprised in the mediation device or managed by said device. The routing function may comprise information regarding types of handled objects, and in a profitable manner, also case names of handled objects. In a useful mode, the routing function also comprises information regarding several other handled objects (for example, in which system they are handled), and the controlled routing can be carried out for operations, directed towards such handled objects, towards another system managed mediation that manages said managed objects. A system including several mediation systems is also provided, in accordance with what is indicated above, said mediation system are interconnected to form a network of managed mediation systems and where the management interface provides communication between a management system and said systems The management system further comprises the additional functionality of providing communication between the managed mediation systems, said management interface profitably supports CMISE services. Accordingly, a method is also provided for carrying out an operation on several managed objects comprised in managed systems said managed systems are handled by a management system that sends a handling operation on a handling interface, said interface therefore provides communication between a management system and several managed systems, said method comprises the steps of: receiving an operation in a managed mediation system; examine whether the managed objects focused by the management operation are included in the managed mediation system or in a managed system managed by said managed mediation system; if it is the case, carry out the operation of handling in the handled objects focused and if it is not the case, to direct the operation to another managed system of mediation. In said other managed mediation system, it is examined if the managed objects are included there or administered in this way. In this case, a handling operation is carried out on the handled objects and, if this is not the case, the handling operation is sent to another managed system of mediation. This can be done in a controlled manner, for example, if a managed reception mediation system preserves information as to which managed objects are handled by managed mediation systems or can be carried out in the form of research (arbitrary or in accordance with given routes) until finding the appropriate managed mediation system. If a managed mediation system of this type is not found, the operation can return from where it came from or a warning can be sent to the management system. A method for adding a managed mediation system to a system that includes a number of managed mediation systems managed by a management system is also provided, through which the managed mediation system is aggregated without requiring the updating of the other systems managed mediation, even when the other managed mediation systems, or some of them can be provided with information in the sense that said managed mediation system has been added in accordance with a modality, and providing communication between the managed system of mediation added and the other mediation systems in a management interface that has the extended functionality of providing communication also between managed mediation systems.

DETAILED DESCRIPTION OF THE INVENTION In figure 1, for reasons of explanation, the management communication between a management system 1A and a managed system 3A is illustrated. In the 3A handling system, several handled objects 5A (hereinafter referred to as Mos) are formed to conform the management view to the driving system 1A.

The handled objects 5A represent resources, indicated here as resource objects (Ros) 6A. The managed system 3A is divided into a handling layer ML containing the handled objects 5A and a resource layer RL containing the resource objects 6A. Only the managed objects 5A can be monitored and controlled, or managed, from the management system ÍA. For example, in the TMN telecommunications management network, standardized managed objects are provided for most applications. The resources can be of different types, such as physical resources, logical resources or functional resources. There does not have to be a managed object for each resource but several managed objects can be implemented as a resource. Each managed object then provides a different management view of the resource. There is a wide variety in the mapping between managed objects and resources. For example, one or more managed objects can represent different views of a resource, a managed object can represent a combination of resources, but a managed object can also represent other managed objects. The management system IA comprises a managed 2A which manipulates the handled objects 5A in the managed system 3A through an agent 4A in the managed system 3A. The administrator 2A establishes an association, which can be considered as a communication link with the agent 4A of the managed system 3A, and when this association is established, the administrator 2A and the agent 4A can communicate. The administrator 2A manipulates the managed object 5A using several defined operations such as to create a managed object, remove a managed object, establish a value in a managed object, obtain a value from a managed object, and an operation known as an action , that is, by making an action on a handled object or by having a driven object perform an action. The managed objects 5A generate warnings that can be sent as event reports to the management systems ÍA; however, this is not part of the present invention. The management system 1A sends handling operations 7A through its managed 2A to the agent 4A of the managed system 3A. In the telecommunications management network (TMN) mentioned earlier in the application, (see also CCITT recommendation M.3010, which is incorporated herein by reference), the management systems ÍA comprise operating systems where the managed systems comprise network elements . Operations and event reports are parts of the common management information service (CMISE). In Figure 2A a management system (MAS) IB manages several managed systems (MS) 4B ?, 4B2, 4B3 through a managed mediation system 2B and a managed system that includes a mediation functionality 3B. In the present invention, the managed mediation systems are also managed systems and may contain several managed objects. They also control several managed systems. A managed system can also be provided with mediation functionality. Mediation is a process that is known from the T-MN concept and is also discussed in Recommendation M.3010 mentioned earlier in this application. In TMN, mediation is a process that acts on the information that passes between functions of network elements and functions of operating systems (among others) and a local management functionality is provided to the network element or to the network elements. Managed mediation systems are later called mediation devices and will be discussed in more detail below. In general, mediation refers to two functionalities, that is, to provide management functionality to groups of similar network elements or to provide management functionality to a network element. In Figure 2B, does an IC management system handle two 3C managed systems?, 3C2 through a managed 2C mediation system (known as MS-MD), which is therefore a managed system that includes a mediation functionality. Obviously, several other alternatives are possible, and the system number handled is obviously not limited to two, but in principle can be any number. This also applies to Figure 2A and to any other figure here. In Figure 2C another example is illustrated in relation to how systems can be fixed. Here a MAS IB manages several 3D managed systems ?, 4D? ...., 4D3 through a managed system of 2D mediation that in turn controls another managed 3D2 mediation system arranged in a lower hierarchical layer and that its once it controls the managed systems 4D?, 4D2,4D3, (here also there can be any number of systems managed as commented above). In Figure 3A, a system operated in the form of a network element (NE) 2E including a mediation functionality (MF) and various network element functions (NEF) is illustrated. Figure 3B shows a managed mediation system in the form of a mediation device (MD) 2F comprising an MF mediation function that controls the functions of network elements NEF in the network elements 3F ?, 3F2. Figure 3A and Figure 3B show consequently the alternative cases in which a managed system or a network element includes both a mediation functionality and the network element functions (NEF) as well as the case of a mediation device that controls the network element functions of two network elements.

Figures 1-3 are shown for the purpose of illustrating some examples as to how the concept of the present invention can be implemented and varied. In Figure 4, a management system (MAS) 10 can send handling operations in a management interface (Mi / f) 15 to several managed systems HA, 11B, 12A, 12B, 12C, 13A, through the systems managed mediation MMS1 11, MMS2 12, and MMS3 13. Thus, the management system 10 controls the managed mediation system 11, 12, 13, which in turn controls the managed systems HA, 11B, 12A, 12B, 12C; 13A. The access points API, AP2, AP3 are identical from the perspective of the MAS 10 and in each AP it is possible to gain access to all the functionality provided by the set of MSSs (with maintenance of protocol characteristics). The invention, however, can also be applied in such a way that not all access points, but a number of them, are identical from a MAS perspective, for example, in very large systems. The management system 10 thus controls managed objects in managed systems. The managed objects are not illustrated and the managed mediation systems 11,12, 13, hereinafter known MMS1, MMS2 and MMS3, respectively, control or manage each of them several managed systems. Thus, MMS1 11 manages managed systems MSi, MS2 HA, 11B. MMS2 controls MS2? 12B, MS22 12B, MS23 12C and finally MMS3 controls MS3? 13A. In accordance with the present invention, the management interface 15 comprises the extended functionality to allow the handling of managed objects that are not recognized by the managed system of receiving mediation. Thus, if, for example, MMSl 11 receives a handling operation that is directed towards a managed object, such as in MS22 12B administered by MMS2 12, the operation is transferred from MMSl 11, to MMS2 12 so it is carried performed an analysis and it is established that MS22 12B is the managed system comprising the focused managed object, and then the operation is sent to MS22 and carried out in a manner known per se. Managed mediation systems can be arranged to form a distributed configuration. In accordance with this concept, each access point must be identical when viewed from the perspective of the MAS mentioned above. At each access point, or through each managed mediation system, it is possible to have access to all the functionality provided by the total set of managed mediation systems with the maintenance of all protocol characteristics. The extended management interface is thus not only used as an interface between the managed system and the managed mediation system, but is also used as an interface between several managed mediation systems and is basically used as a managed system protocol or the Managed mediation systems are defined by a managed system. Through the interconnection of several managed mediation systems it is not required that each managed mediation system can handle all the functionality as required by the management system. For example, each managed mediation system may specialize in a specific area. Each managed mediation system can, for example, specialize for a specific mobile communication system such as NMT, GSM, etc. From a logical perspective, a client will not perceive the managed mediation systems, or particularly the mediation devices, but will perceive them as a managed mediation system (or mediation device) that supports all the client's needs. Profitably you can enter specific areas or new areas of functionality. In a profitable modality, a managed mediation system or mediation device is provided for mobile intelligent network (MIN) services. Since managed mediation systems only pass management operations directed towards MIN MO: s (managed objects) to managed mediation systems for MIN service, a managed system of mediation of particular MIN, or particularly a mediation service, is developed through the use of the particular parameters and services that are necessary without requiring any coordination with other managed mediation systems. Then (according to a specific modality) if a management operation that focuses on MIN MO: s is sent from a MAS, (such as CAS) and is received in another managed mediation system than the system that MIN MO controls: s , the managed system of mediation receiver (MNS) sends the operation another MMS using a default routing that in turn transfers it to find the MMS (for example, newly added). According to one embodiment, new types of managed systems can be directly integrated, particularly network elements, through a mediation device without changing existing products or the network structure through the implementation of the distributed configuration in the network element. The invention therefore solves the problems of product coordination. Managed mediation systems can be added in principle everywhere, in a distributed configuration, for example, in any hierarchical layer or anywhere in a flat structure, which makes the system extremely flexible and a network can be built or increase it in any way. Each object handled MO receives a case name when it is created. All managed objects that are * children "of the same managed object have different case names.The case name does not have to be unique within the managed system but two managed objects can have the same case names provided they have different managed objects parents" . Since in some more managed systems or particularly network elements, the number of handled objects can be very high, they are arranged in what is known as a tree structure. The rules define a management information tree structure (MIT) or an appointment tree. A handled object located immediately below another object handled at MIT is called its subordinate, while an object handled immediately above is known as its superior managed object. However, each handled object will also have a name that is used to identify it, which is unique within the entire managed system and which is a DN distinguished name. The distinguished name starts from the root of MIT and ends with the case name of the handled object. Thus, each MO (and case) has a unique name that includes its representation in the network (the management information base (MIB) which is the model of the network for the managed system of mediation.) In a simplified way, it can be said that the distinguished name DN comprises two parts, ie the case name, which is the unique identity within the particular managed system, and the address of the managed system A managed mediation system uses the case name MO to find the address of the managed system, thus hiding the physical implementation from the management system, according to one modality, an MO has more than a case name (an example is for mobile telecommunication systems, home location records, where a first case name can be the MSISDN and a second case name can be the IMSI code MSISDN is the number of ISDN (Integrated Services Digital Networ) (Mobile Services Integrated Digital Network) which uniquely identifies a mobile telephony subscription in the public switched telephone network numbering plan and IMSI is the International Mobile Subscriber Identity. You can provide conversion methods to move from one case name to another. According to the invention, the management interface is therefore extended insofar as it comprises a routing revision functionality., hereinafter referred to as the DNF distinguished name function. DNF has the functionality to detect if particular MO can be handled by the particular mediation managed system or if it has to be sent to another managed mediation system that recognizes it or that can interpret it. The DNF comprises a list of all recognized MOs. If an unknown MO approach operation is received for DNF, one of two actions can be taken, ie the operation can be rejected and returned to the originator with a message indicating, for example, "case of unknown MO". The operation is redirected to a managed system of default mediation for execution.If a first approach is used, the DNF lists, particularly tables, must be consistent with the set of managed mediation systems.The second approach can be used, for example If a new function, for example a managed mediation system, is added to a network, the existing DNF tables do not have to be updated then, alternatively, a combination of both approaches is used: An additional number of MMS: s , can provide with information or saved information regarding MO: s of one or the other MMS: 2, where the routing is carried out in a controlled manner, at least for In accordance with the present invention, each managed mediation system comprises an agent for the DNF functionality. In addition, in a managed system of mediation, each type of MO (of the MOs managed in this way) is connected to an agent in order to allow the execution of the action requested in the MOs. The DNF agent comprises the routing functionality. In a profitable modality, as will be discussed in more detail below, this agent supports more than a routing alternative, such as a primary route and a secondary route to provide redundancy. In this way, a secure and reliable connection is provided with all the managed systems and the flexibility of the distributed configuration is considerably increased. In another advantageous embodiment, a load sharing between managed mediation systems is provided. The DNF, in addition to recognizing the MO types, also allows the use of MO case names in combination with OM types when an appropriate agent is selected. In this way, both the managed system resources available and the processing resources of the managed mediation system are used efficiently. Systems managed with intensive transaction speeds can then be distributed on a regular basis in several managed mediation systems. Advantageously, said configuration is selected and decided at the time of execution and not in the development stage, which additionally increases the flexibility and the capacity to increase the system. In figure 5A, a system comprising a management system in the form of a CAS 20 client management system which manages several managed systems is illustrated, in this case a home location register HLR1 21A, HLR2 22B, a home office authentication AUC1 21C, a mobile switching center MSC1 22A and MSC2 22B, through a mediation device 21 and a mediation device 22. The management interface is a client management interface with an extended functionality CAIX 25, thus providing communication also between the managed mediation systems MD21 and MD22. As mentioned above, each MD comprises a DNF agent and an agent for each type of MO. These agents, however, are not illustrated in the figure for reasons of clarity. HLRl 21A comprises the handled objects A, B, C HLR2 21 B comprises the handled objects d, e, f, and MSC1 22A comprises the managed objects a, b, ..., m and MSC2 22B comprises the managed objects n, o, ...., Y. For example, Figure 5A refers to a small mixed network (e.g., with less than 500,000 subscribers) and MD21 can illustrate, for example, a mediation device (MD) for GSM and MD22 can comprise an NMT-MD. Evidently they are only examples provided for reasons of explanation. As mentioned above, each MD comprises a DNF comprising lists of recognized managed objects. In Figure 5B, a table of DNF in relation to MD21 is illustrated. As can be seen from the table, HLR of types of MO that includes the cases of handled objects a, b, c and d, e, f, respectively have the system addresses managed, (here network elements), HLRl and HLR2 , respectively. The AUC NE direction of MO type is AUC1 and MSC type MOs are not administered by MD21 but known by MD21 as administered by MD22, which is then provided as the address. In order to illustrate another MSC mode, it is written in parentheses. This shows the case, for example MSC is not included in the list, when a default routing is used, that is, if an operation is received which is directed towards unknown MO: s, this operation is routed to MD22. For similar reasons AUC and HLR in the table of Figure 5C are provided with parentheses if not known, operations that focus on MO: s of this type are routed to MD21. In Figure 5C, the corresponding DNF table 22 is illustrated and elaborated accordingly. As can be seen, MOs of AUC are not administered by MD22 but by MD21 which is provided as an address. Handled objects of type HLR are also managed by MD21. MD21 and MD22 (for example GSM-MD and NMT-MD) can be developed and managed as two totally different products and any of the systems can be updated without interfering or affecting the other system, resulting in a high availability and degree of modularity for the operator. In addition, the testing of new functionalities in any of the systems can be carried out without requiring a new test of the other system and a totally new product can be commercialized, or, alternatively, an increased functionality can be sold. For example, it is possible to start with one of the networks and enter one MD for the other network at a later stage, but also another MD of another system or functionality at another time, etc. Figures 5A-5C illustrate some cases of controlled routing. This will be further discussed with reference to Figures 6A-6D. However, tables can save information as to what to do if operations that are directed towards unrecognized MO: s are received. For example, if M0: 2 of given types or cases of MO of given types are focused, they can be directed systematically for example to MD22 (if they are received in MD21) without MD21 knowing anything as to which MD actually controls them. In addition, any focused MO, but not known, can be routed, for example to MD22. Then, the MD simply sends any operation in which it does not address its own "MO: s." In Figure 6A another modality is illustrated, also in this case in relation to a client management system 30 that handles various elements of network 31A, 31B, 31C, 32A, 32B, 32C, 33A, 33B through mediation devices MD31, MD32, MD33 using an extended client management interface CAIX 35. According to this embodiment a wider mixed network is shown, here it also refers, for reasons of exemplification, to GSM and NMT MD31 is a GSM-MD that administers HLRl, HLR2, HLR3 MD32 is a GSM-MD that manages a message center, a computer identity record and a center Thus, a separate mediation device 32 is added to handle the traffic of message centers and, in this particular case, also to handle low intensity traffic, such as EIR and AUC traffic, but it should be clear that this refers only to a particular mode, and obviously there are no particular reasons why MC traffic, EIR traffic and AUC traffic should be managed by a separate MD; In principle any combination is possible. MD33 here comprises an NMT-MD. HLRl here comprises managed objects A-C, HLR2 comprises MOs d-f, HLR3 comprises MOs g-y, and MSC1 comprises MOs d-m and MSC2 comprises n-y MOs. Figures 6B-6D show, similarly to that of Figures 5B and 5C, the DNF tables for MD31, MD32, and MD33, respectively, however, the last row in Figure 6B illustrates the operations that are focused towards MO: s (or cases of MO), which are not recognized when the analysis is carried out in MD31 are routinely routed (default routing) to MD32. In an alternative embodiment (not illustrated) the address information is preserved only for MO: s controlled through the receiving MD itself. Then, for example, all the operations that focus on these MO: s can be sent to another MD or to the neighboring MD. More generally, the MD stores the information as to where to send unrecognized MO operations. In Figure 7A there is illustrated an embodiment in which redundancy is provided CAS 40 handles HLRl 412A, HLR2 412B, HLR3 412C, MSC1 43A and MSCS 43 B through mediation devices MD41, MD42, MD43. The extended operation interface CAIX45 here provides communication between neighboring MDs MD41 and MD42, MD42 and MD43, respectively, but also between MD41 and MD43. For reasons of simplicity, other network elements are not illustrated except home location registers. Here also it is assumed that MD41 and MD42 are related to GSM while MD43 is related to NMT; the CAS40 here is aware of the 3 mediation devices or access points with their unique addresses and, in the case of access problems to a mediation device, for example, due to a link failure, etc., CAS 40 can reroute the traffic to another MD or to another access point. In Figure 7B, the DNF-41 table is illustrated as the DNF table of MD41. Cases of MO a-c of type HLR have NE address HLRl, cases of MO d-f also of type HLR have direction of NE HLR2 and cases of MO g- and also of type HLR have direction of NE HLR3. MOs of MSC type have MD43 address. In figure 7C, the table DNF42 of MD42 is illustrated. In this case, it is identical with the DNF41 table. The case information of MOs in HLRs 412A, 412B and 412C is therefore contained here in both MD41 and MD42. Figure 7D shows the DNF table, DN43 of MD43. As can be seen from the table, management operations directed towards managed HLR objects can be focused either on MD42 or MD43. With reference to Figures 5A-7A the mediated managed systems have been illustrated comprising GSM and NMT mediation devices, and it should be evident that they could have been any other mobile communication system, such as (D) -AMPS, ADC , PDC, PCN, PCS, private Branch PBX, DECT, etc. They can also relate to particular functionalities and act as a managed mediation system for any managed system that is managed by a management system (which obviously does not have to be a client management system but can be any other operating system or system of management. management in general, the principle remains the same). The mediation devices may also comprise mediation devices for integrated complex mobile intelligent network services and comprise mediation services for generic service adapters for intelligent network services, service management application systems and integrated large integrated MIN services comprising several mediation devices for service management applications. It is also possible to introduce new types of managed systems, or particular network elements, for example, add a new home location register that should be included, for example, in the standard set later. In a particular modality, intelligent mediation devices can be added which present a new functionality (that is, they comprise new MOs) through a combination of already available MOs. An example prefers the creation of an MO for a mobile subscription that comprises several other MOs, for example in suscriberlnHLR, subscriberlnAUC, email, fax mail, personal number, etc. In Figure 8 and Figure 9 there is illustrated an operating system OS 50 in simplified form which controls hierarchically arranged mediation devices, such as for example a GSM-MD 51 that controls a GSM-MD 52 and an NMT-MD 53. Figure 9 shows several MDs arranged in a flat structure where a GSM-MD 61 communicates through an extended interface 65 with an NMT-MD 62 which in turn communicates through the extended interface 65 with a PBX-MD 63 A new MD can be arranged anywhere in a flat structure or anywhere from a hierarchical perspective. It is an advantage of the present invention that the expenses caused by the rerouting of messages or handling operations are small since each node takes only one peak of the message. In addition, in accordance with a profitable modality, each channel is synchronized, which provides a deterministic system that allows easy creation of traffic performance models. However, this is related to a profitable modality; the invention also covers cases with asynchronous channels. Then, however, you must plan a regulation and provide such regulation. In figure 10, a flow diagram schematically illustrates the receipt of an input handling operation to a managed MMS110 mediation system. After the reception of the operation in MMS, 120. Said operation is examined, in accordance with what has been described previously in the application with the use of the DNF routing function, DNF tables, etc., if the operation is focused towards MOs or MO cases that are recognized by the MMS, 130. If the answer is positive, it is established if the MO cases are administered by the MMS, 131. However, if the MOs or MO cases are focused they are recognized, the operation is sent to the next managed mediation system (or to another managed mediation system), 130A. It can be, for example, a neighbor MMS. Alternatively, in a modality in which, for example, the -MMS retains information regarding all MO: s, and the specific MO: s focused by the operation, a rejection notice can be sent to the management system. Then, the procedure according to what is described above is repeated in this last MMS. More generally, instructions can be given to one or several mediation systems only to reject operations that focus on unrecognized MO: s. Also, if a "soft" MMS can not be found, the operation is normally rejected.If the MOs are not managed by MMS, but the management MMS is known 131A, the handling operation is sent to this MMS, 131B, and the operation is sent to the relevant MS, 131C, and the operation is carried out, 131D, in the MOs, however, if it has been detected that the MOs are managed by the first receiving MMS, the operation is sent to the managed system MS administered by this -MMS, 132, and the operation is carried out in the MOs or cases of MO in this MS, 133. According to a profitable modality, a protocol supporting CMISE services is implemented (for example CAI which is a protocol of type CMISE with MOs written in ASCII code) or another interface (for example of the CMISE type) can be used and provided with the extended functionality In one modality, the management interface is described with the use of standard ASN.l (Abstract Syntax Notation One (notaci abstract syntax one), which is a standardized flexible notation that allows the definition of several types of data from simple types such as integers and series of bits for structured types such as sets and sequences as well as complex types defined in terms of others). It is described, for example, in ITU-T X.710, CMISE, Common Management Information Service and X.208, Specification of Abstract Syntax Notation One, which are incorporated herein. by reference. In a useful modality, numerous management interface channels are found between one or several managed mediation systems or mediation devices. In a profitable manner, a consistent review and configuration possibility is offered between several managed mediation systems (particularly mediation devices) using the management interface as a communication channel between managed mediation systems that includes new dedicated MOs for DNF configuration. This allows, for example, the automatic generation of agent codes. It is an advantage of the present invention that a homogeneous interface to the clients can be presented independently of the technology, for example of the mobile communication system, etc. It is also an advantage that a gate product is provided which allows a high degree of expansion in terms of performance and functionality. Synchronous communication, parallel sessions and redundant routes can be used. It is an additional advantage and a product, that is, a managed mediation system or a mediation device can be shared between different organizations, different operators, etc., thus facilitating the management, design, coordination, etc., of the product. It is also an advantage that different functionalities can be implemented in old or new products without affecting the final customer, the management system. Another advantage of the present invention is that it provides a very flexible configuration adaptable to the needs of the clients, that "new" functionalities, etc. can be introduced, when there really is a need for them (and not when the management system is ready). to do it), and that can be freely extended in any way. The invention is not limited to the illustrated embodiments but may vary in numerous ways without departing from the scope of the claims.
