Abstract

A method and a system for charging for message communication, e.g. short messages, in intelligent network applications and especially for charging for message communication by a prepaid subscriber. For charging an intelligent network subscriber for message communication, the message communication bills of the intelligent network subscribers are retrieved from the data collected for message communication charging and the bills are used to update the charging data of the intelligent network. This action is preferably performed periodically.

Claims

1. A method for charging intelligent network subscribers for message communication, in which method

account data of a subscriber is maintained in the intelligent network,

a message communication charging file is formed,

a message communication bill of the intelligent network subscriber is retrieved, and

the account data of the subscriber is updated with the message communication bill.

2. A method as claimed in

claim 1

, wherein

the subscriber is a subscriber using prepaid connection time,

a limit value is set for credit data,

after an update, a check is made to see if the account data is bigger than the limit value, and

if the account data is smaller than the limit value, the use of chargeable message communication services is blocked from the subscriber.

3. A method as claimed in

claim 1

or

2

, wherein the message communication bill retrieval and account data update is performed at predefined intervals.

4. A method as claimed in

claim 1

or

2

, wherein

the account data of the subscriber is maintained in the intelligent network by maintaining a first set of account data on the subscriber'"'"'s balance and a second set of account data on the buffer sums changing the balance,

the account data of the subscriber is updated in two stages.

5. A method as claimed in

claim 4

, wherein

in the first stage, the account data is updated with the message communication bill by adding it to the second set of account data,

in the second stage, the account data is updated utilizing a charging mechanism of the intelligent network by replacing the first set of account data with the sum of the first set and the second set of account data and by initializing the second set of account data after that.

6. A method as claimed in

claim 4

wherein each stage is executed at predefined intervals which need not be the same for both intervals.

7. A method as claimed in

claim 1

, wherein the message communication is short message communication.

8. A telecommunication system comprising

an intelligent network or a connection to an intelligent network,

a network transmitting short messages,

first means for generating a message communication charging file,

memory for maintaining the account data of the intelligent network subscriber,

wherein the system also comprises

second means for retrieving the message communication bill of the intelligent network subscriber from the charging file, and

update means responsive to the second means for updating the account data of the intelligent network subscriber with the message communication bill.

9. A telecommunication system as claimed in

claim 8

, wherein

the subscriber is a subscriber using prepaid connection time,

the update means (SCP, SM-Ch, CI) are arranged to check after the update if the account data is bigger than the predefined limit value and, if the account data is not bigger than the limit value, to send information on this to the network transmitting message communication, and

the network transmitting message communication (PLMN) is arranged, as a response to the information, to block the transmission of chargeable short messages from said subscriber.

10. A system as claimed in

claim 9

, the system comprising at least one mediation device (MD) which, as a response to the information, blocks the transmission of chargeable message communication from said subscriber.

11. A system as claimed in

claim 8

,

9

or 10, wherein the second means are adapted to retrieve credit data at predefined intervals.

12. A system as claimed in

claim 8

,

9

, or 10 wherein

the second means (PSMCC) are arranged to request the update means to update the account data of the intelligent network subscriber, and

the update means comprise a charging interface (CI) which is arranged to update the account data of the intelligent network subscriber as a response to said request.

13. A system as claimed in

claim 8

,

9

, or 10, wherein the message communication is short message communication.
