Embodiment Construction

[0065] 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.

[0066] image 3 It is a schematic structural diagram of a USSD service triggering system in Embodiment 1 of the present invention. Such as image 3 As shown, the USSD service trigger system includes an HSS server, a terminal, an S-CSCF and an access server AS.

[0067] The HSS server sets the Request-URI parameter in the service point trigger SPT that triggers the filter criterion iFC as the service number of the USSD service access code, and sends the trigger filter criterion iFC to the S-CSCF, wherein the service point trigger in the HSS server SPTs are sorted by priority.

[0068] The terminal sends a service request message to the S-CSCF, and distinguishes th...

Abstract

The invention discloses a method, system and terminal for triggering unstructured supplementary service data (USSD) on the basis of an internet protocol (IP) multimedia subsystem (IMS). Firstly, a Request-uniform resource identifier (URI) parameter in a shortest path tree (SPT) of an initial filter criteria (iFC) is set as a service number of a USSD access code; the terminal sends a service request message to a serving call session control function (S-CSCF), and the service request message comprises the service number of the USSD access code and a USSD additional parameter; the S-CSCF acquires the service number of the USSD access code; the S-CSCF utilizes the SPT of the iFC in sequence to be matched with the service number of the USSD access code of the service request message; and if the Request-URI parameter in the current SPT and the service number of the USSD access code of the service request message are consistent, the S-CSCF sends the service request message to an autonomous system (AS) corresponding to the current SPT. By adopting the technical scheme, correct service identification and triggering can be achieved, and a large number of configurations on a service access code parameter are avoided.

Description

technical field [0001] The present invention relates to the technical field of IP Multimedia Subsystem (IPMultimediaSubsystem, IMS), in particular to a USSD service trigger method, system and terminal 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 ga...
