Embodiment Construction

[0060] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0061] image 3 It is a schematic structural diagram of a USSD service triggering system in Embodiment 1 of the present invention. like image 3 As shown, the USSD service trigger system includes an HSS server, a terminal, an S-CSCF and an application server AS.

[0062] The HSS server configures the Request-URI parameter in the service point trigger SPT that triggers the filtering criterion iFC as a USSD service access code, processes it using regular expressions, configures it as a wild card, and sends the triggering filtering criterion iFC to the S-CSCF , where the service point triggers SPT in the HSS server are sorted by priority.

[0063] The terminal sends...

Abstract

The invention discloses an unstructured supplementary service data (USSD) service trigger method and system based on an IP multimedia subsystem (IMS). The method includes: configuring Request-uniform resource identifier (URI) parameters in a service point trigger (SPT) of an initial filter criteria (iFC) into USSD service access codes, processing the parameters through a regular expression and performing configuration in a general configuration mode; enabling a terminal to transmit service request messages to a serving-call session control function (S-CSCF), wherein the Request-URI parameters in a request line comprise the USSD service access codes; enabling the S-CSCF to sequentially use the SPT of the iFC to be matched with the USSD service access codes of the service request messages; and enabling the S-CSCF to transmit the service request messages to an application server (AS) corresponding to the current SPT when the Request-URI parameters in the current SPT are matched with the USSD service access codes contained in the Request-URI of the service request messages. By means of the technical scheme of the USSD service trigger method and system, correct service recognition and triggering can be achieved, and a large amount of configuration work for parameters of the service access codes can be avoided.

Description

technical field [0001] The present invention relates to the technical field of IP Multimedia Subsystem (IP Multimedia Subsystem, IMS), in particular to a USSD service trigger method and system based on the IMS system. Background technique [0002] In the field of IMS technology, the USSD (Unstructured Supplementary Service Data) service is a new service on the mobile network with easy operation and strong scalability. The user can select the menu on the mobile phone and enter a short character string to submit a request to obtain the corresponding information. The format of the input character string is *(#)AAA*BBB#, where AAA is the service number and BBB is the required information Additional parameters, the response method to the USSD service request submitted by the user can be USSD response, short message, fax or E-mail. [0003] Utilizing the USSD service, the following applications can be provided: [0004] Information query (such as flight status, sports game resul...
