Embodiment

[0193] The following describes a typical uplink call USSD business process. The business scenario of this process is that the end user sends a message to the ASP to order a certain service. The ASP asks the end user to select the service type. After the user returns the service type, the ASP replies that the order is successful. message; the process includes:

[0194] Step 1. The terminal sends a USSD message to the USSD GW, and the content of the message is "#124*1#";

[0195] Step 2. The USSD GW sends a data_sm request message to the USSD AGW. The key fields are as follows:

[0196] ussd_servcie_op=0 (PSSR indication)

[0197] message_payload="#124*order#"

[0198] received_message_id="%LOT? SI, 755#PP+C$S, #, U+C

[0199] Step 3, USSD AGW returns a successful data sm reply message to USSD GW;

[0200] Step 4. The USSD AGW matches the access code "124" in the USSD message content, finds the URL address of the corresponding ASP, and sends an uplink handleUssd reque...

Abstract

The present invention provides a USSD AGW, a USSD gateway, and a method for realizing USSD services based on the USSD AGW, wherein the USSD AGW includes: an interface module for providing an ASP network element with a SOAP interface based on a web page service, and completing the USSD service Conversion between SOAP signaling interacting with ASP network elements and SMPP signaling interacting with USSD GW in the process; access authentication management module, used to provide authentication for ASP network elements, and perform access code matching and routing for uplink messages , and controlling the service access times of the ASP network element; and a session control management module, configured to manage and control the session data of the USSD initiated by the ASP network element or terminal. The invention provides relatively convenient access mode of webpage service for ASP, and lowers the technical threshold of ASP's USSD service access.

Description

technical field [0001] The present invention relates to the USSD (Unstructured Supplementary Service Data, Unstructured Supplementary Data Service) value-added service in the communication industry, in particular to a USSD access gateway (AGW), a USSD gateway (GW) system and USSD services based on the USSD AGW Implementation. Background technique [0002] The Unstructured Supplementary Service Data (USSD) service is an interactive data service based on the Global System for Mobile Communications (GSM) network. A typical application scenario is: use the mobile phone keyboard to input some numbers or symbols that have been pre-established by the network, such as "*", "#", etc., and then press the dial (send) key to send an instruction to the service provider (ASP) on the network side. The ASP selects the relevant service content according to the instruction and returns it to the terminal. After the terminal receives the service content of the ASP, it can send the instruction ...
