METHOD FOR PROVIDING INFORMATION TO A SUBSCRIBER OF A MOBILE COMMUNICATION NETWORK
The invention relates to a method for providing information to a subscriber ( 14; 25; 35 ) of a mobile communication network, said method comprising the steps of receiving a call setup message ( 110; 210; 314 ) which is used to set up a call between the originator associated to the call setup message ( 110; 210; 314 ) and the subscriber ( 14; 25; 35 ), detecting ( 111; 213; 315 ) an indicator in the call setup message which indicates the sending of a message to the subscriber ( 14; 25; 35 ), releasing the call ( 112; 215; 316 ) towards the originator and sending ( 114; 217; 318 ) a message to the subscriber.
1 . A method for providing information to a subscriber of a mobile communication network, said method comprising the steps of:
receiving a call setup message which is used to set up a call between the originator associated to the call setup message and the subscriber,
detecting an indicator in the call setup message which indicates the sending of a message to the subscriber,
releasing the call towards the originator
sending a message to the subscriber.
2 . Method according to claim 1 , wherein detecting the indicator in the call setup message comprises the further step of determining an identifier in the call setup message which is indicative of one message out of a plurality of messages and sending the one message out of the plurality of messages to the subscriber in dependence on the identifier.
3 . Method according to claim 1 , wherein the message comprises the indicator in the call setup message.
4 . Method according to claim 2 , wherein the one message out of the plurality of messages comprises a corresponding text which is linked with the identifier.
5 . Method according to claim 4 , wherein the identifier and the corresponding text are stored in a database.
6 . Method according to claim 5 , wherein the database is located in a node of the mobile communication network.
7 . Method according to claim 4 , wherein the text message further comprises the number of the originator.
8 . Method according to claim 1 , wherein the call setup message is an Initial Address Message, IAM.
9 . Method according to claim 1 , wherein the indicator is a routing number prefix.
10 . Method according to claim 2 , wherein the identifier is a suffix value of the call setup message.
11 . Method according to claim 1 , wherein the originator of the call setup message receives a release-indication when the call is released.
12 . Method according to claim 11 , wherein the release-indication is a tone indication.
13 . Method according to claim 1 , wherein after the call is released, a roaming number query is conducted to determine the address of the subscriber.
14 . A switching node of a circuit-switched network, comprising:
a receiving unit, adapted to receive a call setup message which is used to set up a call between the originator associated to the call setup message and the subscriber,
a first processing unit, adapted to detect an indicator in the call setup message which indicates the sending of a message to the subscriber,
a communication unit, adapted to release the call towards the originator,
a sending unit, adapted to send a message to the subscriber.
15 . The switching node according to claim 14 , wherein the switching node further comprises a second processing unit, adapted to determine an identifier in the call setup message which is indicative of one message out of a plurality of messages, and wherein the sending unit is adapted to send the one message out of the plurality of messages to the subscriber in dependence on the identifier.
16 . The switching node according to claim 14 , adapted to perform all the steps of the method of claim 14 .
