Read Acknowledgement Interoperability for Text Messaging and IP Messaging

摘要

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.

1. A method of providing text message read acknowledgement to a mobile device sending a text message, comprising:
inserting, by a mobile phone, a read acknowledgement request in an information-element message associated with an initial text message; transmitting said initial text message with said read acknowledgement request addressed to a recipient mobile phone; receiving, by said mobile phone, a response text message from said recipient mobile phone, said response text message including a read acknowledgement indicator inserted in a response information-element message associated with said response text message; and associating, by said mobile phone, said read acknowledgement indicator with said initial text message.
