Abstract

The embodiment of the invention relates to a method and a device for processing USSD (Unstructured Supplementary Service Data). The method comprises the following steps: when an application server determines that a mobile terminal in a long-term-evolution based voice communication network has the USDD service capability based on an IP multimedia subsystem, the application server sends an invitation message comprising an identity of the USSD service to the mobile terminal through a CSCF (call session control function) entity; the invitation response sent by the mobile terminal through the CSCF entity is received, wherein the invitation response carries the replay message input by a user and the replay message comprises the identity of the USSD service; a message for asking for executing the USSD service is sent according to the replay message and carries the identity of the USSD service; a message for asking for executing the USSD service is sent to a user data server, so that the user data server can process the USSD service according to the identity of the USSD service carried by the message for asking for executing the USSD service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for processing unstructured supplementary service data USSD services. Background technique [0002] Unstructured Supplementary Service Data (Unstructured Supplementary Service Data, referred to as: USSD) service is a new real-time online interactive session data service based on the Global System for Mobile Communications (Global System for Mobile Communications, referred to as: GSM) network; it is based on user The identification module (Subscriber Identity Module, referred to as: SIM) card, which uses the signaling channel of the GSM network to transmit data, is a new service launched on the basis of the GSM short message system technology. [0003] Currently, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, referred to as: 3GPP) standards organization has defined the traditional second generation mobile communication te...
