METHOD AND ARRANGEMENT FOR RECEIVING AND PROCESSING A FAX IN A TELECOMMUNICATION NETWORK
The invention relates to a method for receiving and processing a fax in a telecommunication network.
There are several prior-art methods for receiving a fax by telephone. A user may have a separate fax number receiving only faxes. A fax receiver may also be integrated in normal voice answering service. Both of these prior-art solutions can be implemented in radio networks as well as fixed telephone networks.
The acquisition of a separate fax receiver results in considerable equipment costs for the user. In addition, it is inconvenient to carry a printing fax machine around. In a mobile communication network it is possible to integrate a fax receiver in normal voice answering service, which fax receiver is provided by the network operator. This way, extra equipment costs are eliminated as faxes may be later printed out at a location chosen by the user. However, a problem with a fax receiver integrated in the mobile communication network is that the number of service providers is very limited since the service can be provided only by the user's mobile network operator. This restricts competition on the consumer market, for instance.
An object of the present invention is to reduce the above-mentioned disadvantages associated with the prior art.
In accordance with the invention, faxes addressed to a subscriber are arranged to be directed to an Internet operator arranged so as to channel each user's faxes to the user's mailbox, which may be e.g. the user's home page. The user may then browse the fax on his or her home page or download the fax to his or her mobile phone in a suitable format such as an SMS message (SMS=Short Message Service).
In an advantageous embodiment the telephone subscription attempts to recognize whether an mcoming call is a fax call and makes a call transfer only if that is the case.
The fax receive service according to the invention can be offered by any Internet operator, which means the provision of the service is not tied to any one particular network operator. This means reduced service costs and makes possible the use of one and the same Internet operator from a plurality of mobile and fixed networks.
The method according to the invention for receiving a fax is characterized in that
- a call is directed to a subscriber's number,
- mcoming call is transferred and established to an Internet operator,
- Internet operator identifies the subscriber number/user that transferred the call and saves the fax in an electronic mailbox according to the subscriber number/user identified.
The fax receive arrangement according to the invention is characterized in that it comprises
- means for receiving a fax from an incoming call transferred to it, - means for identifying the subscriber number that transferred the call, and
- means for saving the received fax in a user mailbox reserved for the subscriber number.
Advantageous embodiments of the invention are described below, referring to the accompanying drawings in which

Fig. 4 shows a flow diagram of an advantageous embodiment 40 of the invention.
In Fig. 1 a telephone subscription 100 is typically a fixed telephone or GSM (Global System for Mobile Communications) subscription, but it may be any other mobile subscription such as a CDMA (Code Division Multiple Access), NMT, UMTS (Universal Mobile Telephone Service), Iridium, Inmarsat or Teledesic subscription. Upon receiving a fax the telephone subscription 100 is arranged so as to perform a call transfer to an Internet operator 200. The Internet operator may be any Internet service provider (ISP) offering a fax receive number. The Internet operator 200 is arranged to identify the signal transferred from the telephone subscription 100 and to direct it to an electronic mailbox 300 of the telephone subscription 100. The electronic mailbox 300 may be the WWW home page or e-mail address of the user of the telephone subscription 100 or some other place of storage in connection with the communication network.
In an advantageous embodiment of the invention the Internet operator 200 is arranged to send to the telephone subscription 100 a message, typically a SMS message, about the fax received. In an advantageous embodiment the mobile station of the telephone subscription 100 is arranged to recognize a fax and inform the user about the fax.
In another advantageous embodiment the user may send acknowledgment for a received fax to the sender, e.g. using a SMS message. In these embodiments the telephone subscription 100 is advantageously a mobile subscription.
Fig. 2 depicts an advantageous embodiment 20 of the invention. A call coming from the telephone network 150 into a SS7 circuit (Signalling System No. 7) is routed to a fax receiver 210 of an Internet operator 200. Having received the fax the Internet operator may choose from a plurality of storage methods. The Internet operator 200 may advantageously convert the fax into SMS format 220 or Internet format 230, such as HTML (HyperText Markup Language) or some other World Wide Web format. Furthermore, the Internet operator 200 may convert the received fax into any file 230 that can be simply used in connection with a FTP (File Transfer Protocol) or Telnet based software application. An example of a Telnet based software application is Gopher. In an advantageous embodiment the Internet operator 200 may convert the fax into a FTAM (File Transfer and Access Method) type file 250 so that it can be processed in a versatile manner and independently of the operating system of the host network. In an advantageous embodiment the fax is converte into an audio file 240 either by the personnel of the Internet operator 200 or advantageously using a scanner-speech synthesizer arrangement or in some other way.
The Internet operator 200 is advantageously arranged to save the fax in any format 220, 225, 230, 240, 250 in an electronic mailbox 300. Reading of the messages in the electronic mailbox 300 is advantageously restricted, typically by a scheme in which a password or a personal identification number (PLN) is required so that only the user 400 or advantageously someone authorized by the user 400, such as a secretary, can access the messages in the electronic mailbox 300.
In an advantageous embodiment a message saved in a certain format 220, 225, 230, 240, 250 in the user's electronic mailbox 300 can be read and the user may decide that he or she wants to have the message in some other advantageous format 220, 225, 230, 240, 250. In that case, the user 400 may advantageously send e.g. a SMS message from his or her electronic mailbox 300 to the Internet operator 200 to be converted into WWW format 230, for example. Having converted the SMS message
into WWW format the Internet operator 200 returns the message in the new format to the electronic mailbox 300.
In an advantageous embodiment the user 400 or someone authorized by the user, such as a secretary, may edit the received fax and convert it from any storage format 220, 225, 230, 240, 250 to any other storage format 220, 225, 230, 240, 250 and save the edited message in the user's mailbox 300. Furthermore, the user 400 or someone authorized by the user 400 may also determine in which format 220, 225, 230, 240, 250 the Internet operator 200 should save the message in the user's electronic mailbox 300. The mailbox 300 may be the user's WWW home page, e-mail address or any other place of storage in connection with the communication network.
In an advantageous embodiment of the invention the user 400 may edit the messages in the electronic mailbox 300 through a normal telephone connection, Internet connection and/or digital and/or analog data connection.
Fig. 3 shows an advantageous embodiment 30 of the invention. In this embodiment the user 400 may edit the messages in the electronic mailbox 300 using services provided by an Internet operator 200. In addition, the user 400 may send messages from his or her mailbox 300 via the Internet operator 200 both to the Internet 500 and to the normal telephone network 150.
Fig. 4 shows a flow diagram of an advantageous embodiment 40 of the method according to the invention. A fax call is received for a subscriber's telephone number in step 41. In step 42 a fax file is directed from the subscriber's telephone number to an Internet operator. In step 403 the fax call is received by the Internet operator. Subsequently the fax file may be converted to a desired format in step 44. Possible formats are listed in conjunction with Fig. 2 Finally the fax file is saved in an electronic mailbox, step 45.
The embodiments described above have significant industrial and commercial advantages. The above-mentioned embodiments may be implemented by any Internet operator so that the service is not tied to any particular network operator. This reduces the costs of the fax receive service and makes possible the use of one and the same Internet operator from telephone subscriptions 100, advantageously including mobile subscriptions, of different networks or mobile networks.
The invention was above described referring to specific embodiments. It is, however, obvious that the invention is not limited to just those embodiments, but instead covers all imaginable embodiments according to the inventional idea defined by the independent claims.
