Abstract
Use of information-elements (IE) to enable global system for mobile communications (GSM) devices to support read acknowledgements for text messaging, e.g., short message service (SMS). A GSM device inserts a read acknowledgement request Information-Element (IE) into the body of an SMS message to request that a read acknowledgement be returned to the sending device upon opening. When a GSM recipient device opens an SMS message with a read acknowledgement request IE, the GSM recipient device creates a read acknowledgement SMS message by populating a read acknowledgement message indicator IE, inserting the read acknowledgement message IE into an SMS message, and forwarding the read acknowledgement SMS message to an originating GSM device. Read acknowledgement IEs have a message value that allows a mobile device to associate a read acknowledgement with a particular SMS message. A short message service center (SMSC) supports interoperability between GSM, CDMA, IP, MME, and SMPP read acknowledgements.
