Abstract

In a method for controlling the delivery of short text messages or other messages in a wireless network, a source terminal transmits a message to a recipient wireless unit over the network'"'"'s short messaging service (“SMS”). The message includes a message identifier, a communication identifier of the recipient wireless unit, and message content. Initially, it is determined whether the message satisfies a criterion for blocking the message. If so, the message is blocked. For example, transmission of the message may be blocked if the message identifier is not an authorized identifier. Alternatively, the message may be blocked if the message identifier is an unauthorized identifier. This may be determined by cross-referencing the message identifier to an identifier record of the wireless unit. The identifier record is a data entry, list, or other record associated with the wireless unit for purposes of screening/blocking messages.

Claims

1. A method for communicating with at least one wireless unit over a network, the method comprising:

determining if a message satisfies at least one message blocking criterion associated with the at least one wireless unit, wherein the message is configured for transmission to the at least one wireless unit over a wireless network messaging service, by referencing a message identifier of the message to an identifier record for the at least one wireless unit, wherein the at least one message blocking criterion comprises the message identifier not being listed in an authorized identifiers portion of the identifier record; and

, when so,

blocking the message from at least one of transmission to the at least one wireless unit and display on the at least one wireless unit; and

transmitting an acknowledgement to at least one of a switch portion of the network in communication with the at least one wireless unit and a terminal originating the message, wherein the acknowledgement indicates that the message was blocked and/or not received.

2. The method of claim 1 wherein:

the identifier record is stored on the switch portion of the network; and

the method is carried out at the switch portion.

3. The method of claim 1, wherein the message is blocked from transmission to the at least one wireless unit when the message identifier is referenced in an unauthorized identifiers portion of the identifier record, and wherein the message is blocked from display on the wireless unit unless the message identifier is referenced in the authorized identifiers portion.

4. The method of claim 3 wherein:

the identifier record is stored on the switch portion of the network; and

the method is carried out at the switch portion.

5. The method of claim 1, wherein:

the message is blocked from display on the at least one wireless unit unless the message identifier is referenced in the authorized identifiers portion of the identifier record.

6. The method of claim 5 wherein:

the identifier record is stored on the at least one wireless unit; and

the method is carried out at the at least one wireless unit.

7. The method of claim 1, wherein:

the message is a short text message;

the messaging service is a short messaging service; and

the at least one wireless unit is a mobile phone.

8. The method of claim 1, wherein:

the identifier record is stored in a database in the switch portion of the network;

the message includes a communication identifier of the at least one wireless unit; and

the method further comprises accessing the identifier record by cross-referencing the communication identifier to the database, the communication identifier being associated with the identifier record in the database.

9. A method for controlling delivery of messages to a wireless unit, the method comprising:

referencing a message identifier to an identifier record of the wireless unit, wherein the message identifier is associated with a message configured for transmission to the wireless unit over a wireless network messaging service, and wherein the identifier record includes an authorized identifiers portion and an unauthorized identifiers portion; and

determining whether to block the message based on the message identifier as referenced to the identifier record, wherein the message is blocked from transmission to the wireless unit when the message identifier is referenced in the unauthorized identifiers portion and the message is blocked from display on the wireless unit unless the message identifier is referenced in the authorized identifiers portion; and

, when so,

transmitting an acknowledgement to at least one of a network switch in communication with the at least one wireless unit and a terminal originating the message, wherein the acknowledgement indicates that the message was blocked and/or not received.

10. A method for communicating with at least one wireless unit over a network, the method comprising:

accessing an identifier record in a database based on a communication identifier, wherein the communication identifier is associated with the identifier record in the database and with the at least one wireless unit, the communication identifier being received in a message configured for transmission to the at least one wireless unit over a wireless network messaging service;

blocking the message from at least one of being transmitted to the at least one wireless unit and display on the at least one wireless unit based on a comparison of the identifier record and a message identifier associated with the message, wherein the message is blocked unless the message identifier is referenced in an authorized identifiers portion of the identifier record; and

transmitting an acknowledgement to at least one of a network switch in communication with the at least one wireless unit and a terminal originating the message, wherein the acknowledgement indicates that the message was blocked and/or not received.

11. The method of claim 10 wherein:

the message is a short text message;

the messaging service is a short messaging service; and

the at least one wireless unit is a mobile phone.

12. The method of claim 11, wherein:

the message is blocked from being transmitted to the at least one wireless unit when the message identifier is referenced in an unauthorized identifiers portion of the identifier record and the message is blocked from display on the at least one wireless unit unless the message identifier is referenced in the authorized identifiers portion.
