Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] In order to facilitate the understanding of the technical solutions of the embodiments of the present invention, firstly, a brief description of the USSD (Unstructured Supplementary Services Data, unstructured supplementary service data) involved in the following embodiments is given.

[0034] USSD is defined as a mechanism for transferring information and instructions between mobile stations and network applications, which can pass through the Home Location Register (HLR). It provides mobile communication users with a text-based interface for managing their business. For example, if the user inputs and sends "**21*1234567#SEND" to the network on the mobile phone, all incoming calls of the user will be transferred to the number 1234567. Both USSD and Short...

Abstract

The embodiment of the invention discloses a method used for realizing presence business. The method comprises the steps as follows: an USSD server receives an USSD business application from a mobile station; the USSD server sends a presence business application to a presence server according to an business code in the USSD business application; and the USSD server receives response returned by the presence server and sends the response to the mobile station by the form of an USSD business message. The embodiment of the invention also provides an USSD server, a VLR and an HLR. The embodiment of the invention realizes the interaction of the mobile station and the presence server in a mobile network and satisfies the requirement of the mobile network user towards the presence business.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing a presentation service and a USSD server. Background technique [0002] The presence service (Presence Service) is a communication method based on the SIP protocol. According to certain access rules, the presence information of the user (presence), such as the status, mood, and communication capabilities of the presence, is obtained in real time, and displayed to other users. The business of the user (watcher), so that the watcher can choose an appropriate communication method or time to communicate with the presentity. [0003] Presence server is the main functional entity that realizes the presence service in the network. Its main functions include: storing presence user account information, processing presence user registration, login and various operation applications, receiving presence user status notification or subscription application, etc. [0004] The...
