ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to telecommunications. Specifically, the invention pertains to a device for indirectly forwarding messages in communications networks, i.e., in data and/or communications networks.
National and international laws demand that operators of a public network (and in future this is expected also to apply to private networks) take technical measures to permit the telecommunications traffic to be monitored by so-called users (police, information services, etc.) within the legally provided framework. In classic telephone services in landline networks, this can be done relatively easily in the local switching office of the subscriber to be monitored by marking the appropriate subscriber data record and setting up a type of conferencing circuit for the monitoring user.
For store-and-forward systems, for example voice mail, there is an additional specific requirement: both when writing to or recording messages in the (voice) mailbox and when retrieving or intercepting messages, it should be ensured that monitoring can be carried out by the users. This relates both to the case in which the subscriber to be monitored uses the store and forward system and the case in which the other party with which he is communicating (which does not necessarily have to be a subscriber to be monitored) uses such a system. In addition to the actual message which is forwarded (indirectly) using the store-and-forward system, the intention is that access data will also be determined and transmitted or signaled to the user.
SUMMARY OF THE INVENTION
It is accordingly an object of the invention to provide a device for indirectly transmitting messages in data and/or communications networks, which overcomes the above-mentioned disadvantages of the heretofore-known devices and methods of this general type and which provides a technical Leaching with which the legal requirements can also be fulfilled in the context of store-and-forward systems.
With the foregoing and other objects in view there is provided, in accordance with the invention, a device for indirectly forwarding messages in data and/or communications networks, comprising:
means for storing messages and receiver names or addresses;
means for checking an identification of a subscriber accessing the device;
means for storing information indicating whether a subscriber is to be monitored and, if appropriate, by what monitoring user the subscriber is to be monitored; and
means permitting a message addressed to a given subscriber marked as a subscriber to be monitored to be transmitted to a monitoring user stored for the given subscriber.
In accordance with an added feature of the invention, there are provided:
means for storing information indicating whether a stored message is to be monitored, and if appropriate by which monitoring user;
means for transmitting an indication relating to an access to a given message, marked as a message to be monitored, to a monitoring user stored for the given message.
In accordance with another feature of the invention, means are provided for transmitting an indication to a monitoring user stored for a first subscriber, as soon as a second subscriber accesses a message stored in the device and addressed to the first subscriber, if the first subscriber is marked to be monitored.
In accordance with a concomitant feature of the invention, the indications transmitted to a monitoring user contain information selected from the group consisting of a sender of the given message, receivers of the given message, a time of access to the given message, and a method of access to the given message triggering the indication to be transmitted.
In alternative terminology, there is provided in accordance with the invention, a communications device for indirectly forwarding messages in data and/or communications networks, comprising: a communications processor; a memory device connected to said communications processor for storing messages and receiver identification; said communications processor being programmed to: check an identification of a subscriber accessing the device; store information indicating whether a subscriber is to be monitored and, if appropriate, by what monitoring user the subscriber is to be monitored; and permit a message addressed to a given subscriber marked as a subscriber to be monitored to be transmitted to a monitoring user stored for the given subscriber.
According to the present invention, means for storing monitoring data (subscribers to be monitored, monitoring users, etc.) and for transmitting messages and indications to the users (police, information services, etc.) are provided in store and forward systems. The transmission of these messages and indications is also triggered, inter alia, by access operations to the messages to be monitored or by access operations to messages which are addressed to the subscriber to be monitored.
The store-and-forward system may be implemented here, for example, within an intelligent network or else as a service node or by means of other components in a data or communications network. The communications network may support voice and/or data. The mailbox need not be assigned to a specific terminal (“virtual telephony”).
Mailboxes or devices which are equivalent thereto are known in principle to those of skill in the pertinent art in a large number of widely varying types and designs. Data and/or communications networks are to be understood here basically as being all transmission devices which are suitable for transmitting messages with the involvement of a mailbox. For the invention it is in fact entirely irrelevant what the contents of the transmitted messages are. The mailbox may therefore be a voice mailbox, a data mailbox or any other device for indirectly transmitting messages. The only important factor is that the messages in the mailbox are stored together with the names and/or addresses of the receivers of these messages (cf. FIG.
4
). Means for storing (STM) messages and/or receiver names or receiver addresses are known to the person skilled in the art in a large number of widely varying types and designs (cf. FIG.
5
). The formulation “together with” is intended to mean here that the operating system (operating software and hardware, PCM) or a mailbox device which is equivalent thereto should be capable at any time of determining the receiver or receivers (Rec(Mail)) of a message (Mail) which are defined by the sender (Send(Mail)), and that the operating system of the mailbox should also be capable at any time of finding, for any desired predefined receiver name (Subscr) or for any desired predefined receiver address, all the messages (Pointer(Mail(Subscr))) which (possibly amongst others) are addressed to this receiver. In this context it may quite easily be the case that individual messages, or even all the messages, are public, that is to say are intended to be received by any subscriber. Such public messages could be stored in the mailbox either without naming a receiver or with a corresponding marking.
In addition, means (PCM) are provided for checking the name and/or the address of a subscriber which accesses the device. Such means, generally suitable software modules which run on suitable processors (PCM), are known to those of skill in the art in a large number of widely varying types and designs. The intention here is that initially only the identity of accessing subscribers will be determined. In a preferred embodiment of the present invention, the intention is that it will also be possible to perform surveillance of access operations of different types, that is to say interception, deletion, modification, downloading, etc., for example, as a function of the respective access rights of the accessing subscribers.
In addition, the invention provides means for storing information which indicates whether a subscriber is to be monitored and, if appropriate, by which monitoring user this subscriber is to be monitored. These means may be implemented, for example, by means of a table whic
