Description
SYSTEM AND PROCEDURE FOR DIRECTING A SHORT MESSAGE
The present invention relates to a system and a procedure for directing a short message to a virtual subscriber number in a telecommunication network com-prising a mobile communication network. The invention also relates to a system and a procedure for directing a short message to a customer-specific VPN subscriber num-ber (Virtual Private Network, VPN) in a telecommunica-tion network comprising a mobile communication network.
PRIOR ART
In the GSM system, the subscriber can send and receive short messages in text form. In addition, vari-ous intelligent network services have been introduced in the GSM system which allow a call to be directed to vir-tual numbers in the telecommunication network. One of such services is virtual subscriber number. Calls made to such a number are directed to the subscriber s actual number. Examples of this service are free numbers begin-ning with 0800 and national call numbers of enterprises.
In the Virtual Private Network (VPN) service, individual subscribers are so grouped that the network looks like a private branch exchange to the subscriber. Calls can therefore be made from a mobile station to another mo-bile station or to an ordinary telephone connected to a branch exchange by using only extension numbers. Al-though the above-mentioned intelligent network services have been introduced, it has only been possible to util-ise them in conjunction with calls. It has not been pos-sible to send short messages to users of intelligent network services utilising virtual numbers.
The object of the present invention is to eliminate the drawbacks described above. A specific ob-ject of the invention is to disclose a new type of sys-tem and procedure that make it possible to direct short messages to virtual subscriber numbers.

In the procedure of the present invention for directing a short message to a subscriber-specific VPN
subscriber number in a telecommunication network com prising a mobile communication network, which comprises a mobile services switching centre (MSC) serving the A
subscriber, a routing centre for routing short messages in the direction mobile station - short-message service centre - (SMS-IWMSC), a short-message service centre (SMSC) for the reception, storage and transmission of short messages and a service database (DB) for maintain-ing intelligent network service data, and to which is connected a service node for establishing the interna-tional subscriber number (MSISDN) corresponding to the subscriber-specific VPN subscriber number, a short mes-sage addressed to a subscriber-specific VPN subscriber number is transmitted from the mobile services switching centre (MSC) to the service node. In addition, the A-subscriber has replaced the address of the short-message
7 service centre (SMSC) with the address of the service node in the address field of his/her terminal device.
Next, a service inquiry containing the A
subscriber's international subscriber number (MSISDN) 5 and the B-subscriber's customer-specific VPN subscriber number as parameters is sent from the service node to the service database (DB). In response, the B-subscriber's international subscriber number (MSISDN) is sent from the service database (DH) to the service node.
10 Next, the address field parameters of the short message are changed in the service node in such manner that the B-subscriber's customer-specific VPN subscriber number is replaced with the B-subscriber's international sub-scriber number (MSISDN) and the address of the service 15 node is replaced with the address of the short-message service centre (SMSC).
After this, the short message is transmitted from the service node to the routing centre (SMS-IWMSC).
An acknowledgement of receipt of the short message is 20 then sent from the routing centre (SMS-IWMSC) to the service node, and the acknowledgement is transmitted further to the mobile services switching centre (MSC) after the global title (GT) has been converted into the address of the mobile services switching centre (MSC).
25 In an embodiment of the procedure, the address field parameters of the short message are changed in the service node in such manner that the address of the service node is replaced with the address of a default short-message service centre (SMSC), whereupon the short 30 message is transmitted from the service node to the routing centre (SMS-IWMSC), whereupon an acknowledgement is sent from the routing centre (SMS-IWMSC) to the serv-ice node, which acknowledgement is transmitted to the mobile services switching centre (MSC) if the B-35 subscriber's international subscriber number (MSISDN) is not found in the service database.
Next, a service inquiry containing the A
subscriber's international subscriber number (MSISDN) 5 and the B-subscriber's customer-specific VPN subscriber number as parameters is sent from the service node to the service database (DB). In response, the B-subscriber's international subscriber number (MSISDN) is sent from the service database (DH) to the service node.
10 Next, the address field parameters of the short message are changed in the service node in such manner that the B-subscriber's customer-specific VPN subscriber number is replaced with the B-subscriber's international sub-scriber number (MSISDN) and the address of the service 15 node is replaced with the address of the short-message service centre (SMSC).
After this, the short message is transmitted from the service node to the routing centre (SMS-IWMSC).
An acknowledgement of receipt of the short message is 20 then sent from the routing centre (SMS-IWMSC) to the service node, and the acknowledgement is transmitted further to the mobile services switching centre (MSC) after the global title (GT) has been converted into the address of the mobile services switching centre (MSC).
25 In an embodiment of the procedure, the address field parameters of the short message are changed in the service node in such manner that the address of the service node is replaced with the address of a default short-message service centre (SMSC), whereupon the short 30 message is transmitted from the service node to the routing centre (SMS-IWMSC), whereupon an acknowledgement is sent from the routing centre (SMS-IWMSC) to the serv-ice node, which acknowledgement is transmitted to the mobile services switching centre (MSC) if the B-35 subscriber's international subscriber number (MSISDN) is not found in the service database.
8 In an embodiment of the procedure, the address field parameters of the short message are changed in the service node in such manner that the address of the service node is replaced with the address of a default short-message service centre (SMSC), whereupon the mes-sage is transmitted from the service node to the routing centre (SMS-IWMSC), whereupon an acknowledgement is sent from the routing centre (SMS-IWMSC) to the service node, which acknowledgement is transmitted to the mobile serv-ices switching centre (MSC) if a message addressed to an international subscriber number (MSISDN) has been sent to the service node.
As compared with prior art, the present inven tion provides the advantage that it makes it possible to send short messages to users of intelligent network services who utilise virtual numbers, which has not been possible before. In the system and procedure for direct-ing a message to a virtual subscriber number, short mes-sages can be sent by all users of the short-message service. A further advantage is that, from the user's point of view, there is no difference between virtual subscriber numbers and normal MSISDN numbers. On the other hand, the system and procedure for directing a message to a subscriber-specific vPN subscriber number make it possible to provide a short message service sup-porting the intelligent network VPN service, thus allow-ing short messages to be sent to an extension number consistent with the VPN service. A further advantage of the invention is that it allows an independence of the supplier of the short-message service centre (SMSC) be-cause the service node is implemented as a unit separate from the short-message service centre (SMSC). Moreover, a short message sent by the method of the invention can be answered by using a REPLY function.

DETAILED DESCRIPTION
Fig. 1 presents an example of a physical con-20 figuration for a system for directing a short message to a virtual subscriber number in a telecommunication net-work comprising a mobile communication network, such as a GSM network. The short-message service centre 1, known in itself, takes care of receiving short messages from 25 the sender, delivering them further to the receiver and storing them until they are successfully transmitted.
The routing centre 2, also known in itself, takes care of routing the short messages from the short-message service centre 1 to the B-subscriber. A new type of 30 routing centre 2 function provided by the invention is performing a GT analysis on a virtual number direction.
The mobile services switching centre 3 is in itself a known mobile services switching centre serving the B-subscriber. The home location register 6 is in itself a 35 known home location register and it stores the sub-scriber information for the B-subscriber. A completely new type of element provided by the present invention is the service node 4. By utilising the services provided by the service node, it is possible to direct short mes-sages e.g. to national call numbers of enterprises. The 5 home location register 6 and the routing centre 2 are so connected via the service node 4 that the service node 4 is transparent both to the home location register 6 and to the routing centre 2, in other words, the service node 4 is seen by the routing centre 2 as the home loca-IO tion register 6 and by the home location register 6 as the routing centre 2. The action of the service node 4 is not visible to the user's terminal device. The data-base 5 is used to store subscriber-specific intelligent network service data. It may be either an external in-telligent network service database known in itself or it may be integrated with the service node 4.
Fig. 2a presents a signalling example for a procedure for directing a short message to a virtual subscriber number in a case where the transmission of a short message is successful. The short message has been received at the routing centre 2, which, based on the virtual number of the receiver of the short message, finds the address of the service node 4 representing the home location register 6. From the routing centre 2, a SEND_ROUTING_INFO FOR SHORT MESSAGE routing inquiry con-sistent with the MAP protocol is sent to the service node 4. The routing inquiry carries the following pa-rameters Parameter Description l Invoke Id Identif ier of the MAP service primitive MSISDN Receiver's virtual number SM-RP-PRI parameter indicating whether transmission of the short message to the receiver is to be attempted even if the home location register has other short messages waiting SC Address Address of the short-message service centre

The home location register 6 is in itself a 35 known home location register and it stores the sub-scriber information for the B-subscriber. A completely new type of element provided by the present invention is the service node 4. By utilising the services provided by the service node, it is possible to direct short mes-sages e.g. to national call numbers of enterprises. The 5 home location register 6 and the routing centre 2 are so connected via the service node 4 that the service node 4 is transparent both to the home location register 6 and to the routing centre 2, in other words, the service node 4 is seen by the routing centre 2 as the home loca-IO tion register 6 and by the home location register 6 as the routing centre 2. The action of the service node 4 is not visible to the user's terminal device. The data-base 5 is used to store subscriber-specific intelligent network service data. It may be either an external in-telligent network service database known in itself or it may be integrated with the service node 4.
Fig. 2a presents a signalling example for a procedure for directing a short message to a virtual subscriber number in a case where the transmission of a short message is successful. The short message has been received at the routing centre 2, which, based on the virtual number of the receiver of the short message, finds the address of the service node 4 representing the home location register 6. From the routing centre 2, a SEND_ROUTING_INFO FOR SHORT MESSAGE routing inquiry con-sistent with the MAP protocol is sent to the service node 4. The routing inquiry carries the following pa-rameters Parameter Description l Invoke Id Identif ier of the MAP service primitive MSISDN Receiver's virtual number SM-RP-PRI parameter indicating whether transmission of the short message to the receiver is to be attempted even if the home location register has other short messages waiting SC Address Address of the short-message service centre
11 Next, a database query based on the MSISDN pa-rameter of the SEND~ROUT~ING-INFO_FOR SHORT MESSAGE mes-sage is sent from the service node 4 to the service da-tabase 5. If the number is not found in the database 5, 5 then the service node 4 responds with a SEND_ROUTING_INFO-FOR-SHORT MESSAGE ACK message contain ing an °Unknown Subscriber~~ error message in its User Error field. Otherwise, the B-subscriber's actual inter national subscriber number (MSISDN) is returned from 10 the database 5.
Based on the actual international subscriber number (MSISDN) , the service node 4 gets the address of the B-subscriber s home location register 6 and sends it a SEND,ROUTING-INFO_FOR SHORT MESSAGE query. In its 15 SEND_ROUTING~INFO_FOR_SHORT MESSAGE_ACK response, the home location register returns the following informa-tion:
Parameter Description Use Invoke Id Identifier of the MAP sere- Obligatory ice primitive Code identifying the sub- Conditional scriber MSC Number Address of the mobile sere- Conditional ices switching centre ~I Local (temporary) code Conditional identifying the subscriber Uaer error Cause of a user-related er-reactor Provider error Cause of a s stem error O tional 20 The SEND ROUTING_INFO_FOR SHORT MESSAGE_ACK
message is transmitted unchanged from the service node 4 to the routing centre 2. The routing centre 2 sends the short message further to the mobile services switching centre 3, which acknowledges receipt of the same.

The mobile services switching centre 7 is in itself a known mobile services switching centre serving the A-subscriber. As a new type of function provided by the invention, the mobile serv-ices switching centre 7 performs a GT analysis on the number of the service node 8. The routing centre 9, also known in itself, takes care of routing short messages from the A-subscriber to the short-message service cen-tre 10. The short-message service centre 10, known in itself, takes care of receiving short messages from the sender, delivering them to the receiver and storing them until successfully transmitted. A completely new type of element provided by the present invention is the service node 8. By utilising the services provided by the serv-ice node, it is possible to direct short messages to in-telligent network vPN numbers. The mobile services switching centre 7 and the routing centre 9 are so con-nected via the service node 8 that the service node 8 is transparent both to the mobile services switching centre 7 and to the routing centre 9, in other words, the serv-ice node 8 is seen by the routing centre 9 as the mobile services switching centre 7 and by the mobile services switching centre 7 as the routing centre 9. The user's terminal device sees the service node 8 as the short-message service centre 10. The database 11 is used to store subscriber-specific intelligent network service data. It may be either an external intelligent network service database known in itself or it may be integrated with the service node 8.
14 Fig. 4a presents a signalling example for a procedure for directing a short message to a subscriber-specific VPN subscriber number in a case where the transmission of the short message is successful. The A-subscriber has changed the address of the short-message service centre 10 in the address field of his/her termi-nal device into the address of the service node 8 and sent a short message to a VPN number. The short message is transmitted from the mobile services switching centre 7 serving the A-subscriber to the service node 4 8 in a MAP,FORWARD_SHORT MESSAGE message, whose title fields contain the following information, which is identified by a MAP object in the service node 8 Parameter Description Chaage Invoke Id Identifier of the MAP sere- Not to be ice primitive changed SM-RP DA User-defined address of the To be short-message service centre changed SM-RP OA Sender's international sub- Not to be scriber number (MSISDN) changed SM-RP UI SM-TP DU, data processed by Certain pa-short-message service centre rameters to be changed The SM-RP UI (User Information, Ui) contains the following information, which is identified by a SM-TP object in the service node 8 from a SM-TP-SMS-SUBMIT

The service node changes the parameters in such 10 manner that, in the SM-RP DA parameter, the address of the service node 8 is replaced with the address of the short-message service centre l0 and, in the SM-TP DA pa rameter, the VPN number is replaced with the MSISDN num-ber. Next, the service node 8 sends the short message to the routing centre 2 in a MAP FORWARD SHORT MESSAGE mes-sage.
5 The routing centre 9 acknowledges receipt of the short message by sending the service node a MAP FORWARD_SHORT MESSAGE ACK message, which is sent by the service node 8 to the mobile services switching cen-tre 7 in the form in which the mobile services switching 10 centre 7 would have received it directly from the rout ing centre 9, which means changing the GT address of the message. The parameters of the MAP_FORWARD_SHORT MESSAGE ACK message are Invoke Id and, in the case of an error, User error, which indicates the IS cause of the failure.
Fig. 4b presents a signalling example for a procedure for directing a short message to a subscriber-specific VPN subscriber number in a case where a short message has been sent with an ordinary MSISDN number.
20 Based on the TP-DA parameter, the service node 8 identi-fies the short message as an ordinary short message sent with a MSISDN number. No database query is needed, but the short message can be transmitted directly to a de-fault short-message centre in a 25 MAP_FORWARD_SHORT MESSAGE message. The service node 8 changes the message parameters in such manner that, in the SM-RP DA parameter, the address of the service node 8 is replaced with the address of the default short-message service centre. Next, the service node 8 trans-30 mits in a MAP_FORWARD SHORT MESSAGE ACK message an ac-knowledgement from the routing centre 9 to the mobile services switching centre 7 which sent the message.
Fig. 4c presents a signalling example for a procedure for directing a short message to a subscriber 35 specific VPN subscriber number in a case where the sub scriber is not found in the service database 11. In this case, the service node 8 receives as a return value from the database 11 a database error indicating that the subscriber is not found. The service node 8 sends the short message to a default short-message centre in MAP FORWARD SHORT MESSAGE message after changing the 5 message parameters in such manner that, in the SM-RP DA
parameter, the address of the service node 8 is replaced with the address of the default short-message service centre.
