User Data Header

Abstract: A message processing system is a server ( 1 ) incorporating software functions ( 15 ) which operate without user intervention to intercept ( 16, 17 ) SMS text messages, to translate the original text content in the short message body to compress it, and to forward the converted message on in the network. The content compression frees up space, and some or all of this space may be taken up by addition of tagging information such as text tags or sponsored or advertising content or user data header (UDH) information elements. The translator is part of a message converter ( 15 ) and parses the content and identifies candidate words for translation, and then iterates over the content, replacing the candidate word to allow the addition of one or more text tags to the message. The translation could be performed on just enough words and phrases to free up the required space, or it could be on the message as a unit, so as it give it uniformity of presentation. In one aspect, the invention has the major advantage of achieving compression of content to free up space for other information, but not having any impact on downstream network elements or the recipient device or application. It is completely transparent to the receiving device or application.

Abstract: The invention discloses a realizing method, a realizing device and a realizing system for deleting short messages (SMS) automatically The method comprises the following steps that: when a mobile telephone of a sender packs and sends the SMS needing to be kept confidential, an SMS header which contains automatic deleting configuration information is added; and then a mobile phone of a receiver determines whether the automatic deleting function is started for the short message or not according to the SMS header information The device comprises a packing and sending module and an automatic deleting function starting module The method, the device and the system send the SMS with automatic deleting function by using the expansion of the SMS header TP-UDH (Transfer Protocol User Data Header) in an SMS protocol, and the mobile phone which supports and analyzes the new added protocol receives the SMS and stores the SMS; and after a customer reads the SMS, the SMS can be deleted automatically, so even if the mobile phone is lost, the content of the SMS is not let out

Abstract: Short messaging service (SMS) is perhaps the most popular mobile technology prevalent among students in higher education due to its ubiquitous nature and the capability of two-way communication. However, a major limitation in two-way text messaging is sending back a part of received data with the reply message. This limitation results in users of a mobile learning environment being unable to reply back to the correct destination. This article presents a two-way text messaging system that can be integrated into a learning management system (LMS) to provide an interactive learning experience to the user community. Initially, a database is integrated into the LMS that holds message information such as recipient’s phone number, message body and user data header. A specific port associated with the SMS is used to conceal and exchange data of a particular course unit. Subsequently, software in the student’s mobile device captures this message and sends back the reply message to the appropriate course unit allowing both teachers and students to view messages sent and replies received pertaining to a particular course. Results indicate the educational impact of the proposed system in improving the learning environment and benefits it offers to the community in a campus-wide implementation.

Abstract: This invention puts forward a complementary protocol to the USSD signaling layer protocol to expand the function sphere of USSD in the modern communication network including two parts: 1, putting the content unable to be contained in one message in multiple messages and transmitting them by adding UDH(user data header) fields in the ussd-String to split the messages at the transmitting end and utilize the sequence number identification sum to regroup them at the receiving end, 2, putting simple multimedia contents and transmitting them in the UDH
