Problems solved by technology

However, since different types of data services occupy different data ports, once all the data ports of the UE are occupied, the software or hardware architecture must be modified to expand the new data ports to implement USAT data services. Once the software or hardware architecture If it is determined, it will be difficult to add a new USAT data port, and the USAT data service cannot be realized normally.

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, a method for realizing the USAT data service of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] In order to simplify the development process of the application layer and improve the development efficiency, the present invention proposes a method in which only AT commands are interacted in the application layer, and the processing of USAT data is concentrated between the control plane and the user plane.

[0036] For the USAT data service - sending data (SEND DATA), the UICC will first require the terminal to open the channel according to the specified parameters, and this operation can be completed through standard AT commands. When the channel is successfully established, the next step is to send data (SEND DATA). The application layer encapsulates the data in the form of AT commands and ...

Abstract

The invention relates to the field of communication, in particular to a method for realizing USAT data service. By information mutual conversion between a user plane and a control plane, an AT command is used for carrying the converted information of the user plane and the control plane to realize the data interaction between UICC and a network terminal. When the USAT data service needs to be realized, the invention does not need to open up a special data port for the USAT function data service, can not influence the prior software and hardware configuration and can realize the USAT data service flexibly according to the function requirement.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing data services of a Universal Subscriber Identity Module (USIM for short) Application Toolkit (USAT for short). technical background [0002] A Universal Subscriber Identity Module (abbreviated as USIM) is an important component unit of a third-generation mobile communication user terminal (abbreviated as 3G UE), and its physical entity is a Universal Integrated Circuit Card (abbreviated as UICC). As an application built on the UICC, the USIM is mainly used for identification of terminal users and as a carrier of application services. With the help of USIM Application Toolbox (abbreviated as USAT) technology, the application in UICC and the UE supporting the application can perform interactive operations through a series of USAT commands, so that mobile users can have personalized additional services. [0003] The series of USAT commands that the UICC interacts wi...
