Abstract

Short message system (SMS-MO) comprising switching arrangements (MSC) and servers (SMSC) at which the messages arrive in the form of messages “destined for a mobile” (SMS-MT). The sending mobile (SMS-MO) includes in the message the address of the server (SMSC) of its card (SIM). The system comprises a virtual server (SMSC-V) which is defined by its address (ADR-V) and is associated with an operator, a real server (SMSC-R) which is defined by its address (ADR-R), the address (ADR-V) of the virtual server (SMSC-V) being the only server address recorded on the operator'"'"'s cards (SIM), the switching arrangement (MSC) contains an address translator for replacing the address of the virtual server (SMSC-V) with that of the real server (SMSC-R) to which the message (SMS-MO) will be routed, which real server handles the message and routes it to the intended receiver (MO′).

Claims

1. Short message system for handling short messages (SMS-MO) sent by mobiles (MO), comprising switching arrangements (MSC) on which the mobiles (MO) depend for radio connection, and short message servers (SMSC) at which the messages from a mobile (SMS-MO) arrive and are routed back, in the form of messages “

destined for a mobile”

(SMS-MT), to the destination mobiles (MO′

),

the mobile sending messages (SMS-MO) including in the message the address of the server (SMSC) of its card (SIM),

which system is characterised in that it comprises

a virtual server (SMSC-V) which is defined by its address (ADR-V) and is associated with an operator,

a real server (SMSC-R) which is defined by its address (ADR-R),

the address (ADR-V) of the virtual server (SMSC-V) being the only server address recorded on the cards (SIM),

the switching arrangement (MSC) contains an address translator for replacing the address (ADR-V) of the virtual server (SMSC-V) with that (ADR-R) of the real server (SMSC-R) to which the message (SMS-MO) will be routed, which real server handles the message and routes it to the intended receiver (MO′

).

2. Short message system according to claim 1,

characterised in that

the real server (SMSC-R) is located in a different country from that of the operator, and the connection between the switching arrangement (MSC) of the operator visited by the transmitting subscriber (MO) and the real server (SMSC-R) is made by way of the international network (SS7).

3. System according to claim 1,

characterised in that

the virtual server (SMSC-V) has an address in the country of the operator on which the subscriber (MO) sending the message (SMS-MO) depends.

4. Short message system according to claim 1,

characterised in that

it comprises, for prepaid subscribers, a prepaid card database (BD-CP RP) containing the credit accounts of prepaid short message cards and the associated code numbers, a prepaid short message card (CA), having a secret code (CD), which the subscriber purchases and the secret code (CD) of which he uses and includes in his short messages (SMS-MO), in the case where there is no interactive vocal server (SVI) for top-up, the real short message server (SMSC-R) receiving a short message (SMS) from a mobile and verifying authorisation of transmission by checking the code (CD), if there is one, and the account credit assigned to that code (CD) in the prepaid card database (BD-CPRP), and it sends the message to the intended receiver (SMS-MT) if the credit permits, and otherwise the server (SMSC-R) sends a credit exhaustion message to the mobile (MO) sending the message (SMS-MO).

5. System according to claim 2,

allowing the real server (SMSC-R) to supply the short message service (SMS-MO) also to non-prepaid subscribers without checking the secret code, solely on the basis of the number of the sending subscriber, by obtaining the subscriber profile from the HLR in order to ascertain whether the subscriber is prepaid or not, especially by behaving like a VLR carrying out the GSM location update procedure (MAP-UPDATE-LOCATION) without there actually being a location update.
