According to Fig. 1, the services are shown above a broken horizontal line 9 which symbolises that, in accordance with a preferred structure of the invention, the services are not implemented within the networks inaccessible from the outside but are invoked according to need or options in such a manner that the users do not recognise any significant change, if at all, regarding the provided services and service handling even when roaming and changing the attached network and/or the used equipment (such as terminal equipments 8, 15, 22, 23).
- Such services can be provided by the network or by the terminal or by both the network (s) and the terminal (s ) .

- the database 4b stores profiles for users which are allowed to roam between the different networks such as shown in Figure 1.
- the contents of database 4b essentially comprises two parts: a first part describes the terminal properties of the terminal equipments assigned to or accessible by certain or all users. This part may store information on all terminal equipments connectable to the networks. In this database part, information on the types, properties, specifications (e.g.
- database 4b services provided or selectable for the respective users are registered. E.g., services actively activated by a user, or services forcibly provided for the users such as charging service 3, are marked, in the database, as active services.
- a user roams, i.e. attaches, to another network, or starts to use another terminal equipment the database 4b is checked by this another network or some other function, or by the network to which the newly used equipment starts the attachment process, for retrieving information on activated services.
- this service (s) is invoked, or maintained, also for this new network and/or newly used terminal equipment.
- the broker 4a may be implemented as an object request broker (ORB) which may have a CORBA structure, or as a SOAP/DEN implementation.
- CORBA stands for "Common Object Request Broker Architecture" such as specified by the Object Management Group (OMG) .
- CORBA addresses interoperability in distributed heterogeneous environments, and can be conceptualized as a communication bus for client-server objects.
- CORBA is a three- tier distributed object mechanism so that the terminology "client-server" applies within the context of a specific request. If one of the networks 11, 13, 20, 21 invokes a service from the service devices or functions 1, 3, 5, 6 and/or 7, the network can be termed client, and the service providing device or function can be termed server.
- Exported server interfaces can be specified in a CORBA standard interface definition language (IDL) .
- IDL interface definition language
- the broker 4a can have such a CORBA structure, or can be implemented in any other suitable manner which ensures that a requested service is appropriately invoked and provided.
- the broker may also be implemented by e.g. using SOAP (Simple Object Access Protocol) and an advanced DNS (Domain Name Service) such as Microsoft DEN.
- SOAP Simple Object Access Protocol
- DNS Domain Name Service
- Figure 1 shows a global view of the provision of services (e.g. communication services) over a hybrid network structure. Further details of the structure and of the method of functioning and operation of the embodiment will be described below.
- the service or services presently activated for one or more users e.g. subscribers to a specific network or visiting users only temporarily present in a network
- Services will either be transferred or are resident on one or more terminal equipments (network elements) used by the user(s) and access the network functionality through a standard interface in a preferably secure environment.
- the services may also at least be partly provided by the network to which a user is presently attached when e.g.
- the terminal resources often the terminal equipment should not be sufficient for instance for voice recognition, or when the implementation of the activated service or services is better implemented within the network, or when e.g. network legacy resources, e.g. for lawful interception or the like, have to be accessed.
- API application programming interface
- SE 18 standard environment
- the standard environment (SE) 18 When services run on the end user terminal equipment such as network element 8, 15, 22 or 23, the standard environment (SE) 18 provided in and by the terminal equipments allows the services to act in a standardized way.
- the standard environment 18 takes care of security matters and defines a standard API (Application Programming Interface) toward the network (e.g. charging, call processing, messaging etc.).
- a standard environment 18 may be, in a GPRS environment, e.g. terminal equipment 8 and network 11, the standard environment called MExE (Mobile Station Application Execution Environment) .
- MExE Mobile Station Application Execution Environment
- Such a standard environment of MExE or other type is extended, i.e. implemented, in the terminal equipments 15, 22, 23 etc. attributed to the users, that is to all terminals on the packet based networks (PBN) which the user may use. This ensures that a standard and stable environment exists on all the terminals to which the user or users may have access. Therefore, services are able to flow freely between terminals of
- the standard network API is indicated, in Figure 1, by the broken line 9 on a superordinate level.
- each network will implement, or have access to, such a standard network API.
- This standard network API is represented by a broken line within each network which standard API has an "a" attached to the reference numeral of the associated network (standard API 13a for network 11, standard API 13a for network 13, standard API 20a for network 20, and standard API 21a for network 21) .
- This network API 11a, 13a, 20a, 21a is standardized for each network so that the broker 4a has to communicate with only one one standard interface type independent of the network actually provided behind this standardized API.
- This configuration contributes to open up traditional telecommunication networks and renders available at least one, several or all network-based services in a standardized way.
- the terminal services described above such as the standard environment
- the standard network API 11a, 13a, 20a, 21a so as to build a strong environment for rendering available services in a reliable manner across • networks and terminals.
- a network API may be used as defined e.g. by the Parlay organization.
- the networks as such may also remain basically unchanged in their structure, and the application programming interface 9 may provide the necessary standardized interface function.
- a gateway may be provided which is able to communicate with each of the network of the hybrid network structure (here: networks 11, 13, 20, 21) and which communicates with the standard application programming interface 9 so as to provide the connections between the networks and the broker 4a.
