Example two
The technical solution of the present invention is further explained below.
As shown in fig. 6, the RCS terminal and the IMS core network may be implemented in the following signaling interaction manner:
after the RCS terminal is registered in the IMS core network, the RCS terminal actively sends a SUBSCRIBE subscription request to the IMS core network to SUBSCRIBE the detailed information of the current downloadable application. In the subscription message, the Accept field is to be extended, and a new message body format, such as application/apkinfo + xml, is defined for the list of downloadable application information. After receiving the request, the IMS core network sends a 200OK response to the terminal to indicate that the request is accepted. And then sending a NOTIFY message to the terminal, wherein the format of the message body carried in the message is consistent with the Accept field value in the SUBSCRIBE message, and the content of the message body is a downloadable application information list requested by the terminal. And the RCS terminal returns a 200OK response after receiving the NOTIFY. And the RCS terminal analyzes the message body after receiving the NOTIFY, acquires the downloadable application information and presents the downloadable application information to the user. When the information of the application file is updated, the IMS core network also sends a NOTIFY message to inform the terminal.
And the RCS terminal analyzes the message body after receiving the NOTIFY message, displays the analyzed information of the downloadable application file in an interactive interface and presents the information to the user. The user may select an application download while browsing application file information.
If the user selects a certain application file to download, the RCS terminal firstly sends a MESSAGE to the IMS core network, and the MESSAGE can adopt a fixed format to write information with the specific application file and inform the IMS core network that the terminal needs to download the application.
After receiving the MESSAGE, the IMS core network returns a 200OK response, and then downloads the application file by sending the file, that is, sending a MESSAGE in a large MESSAGE mode, between the IMS core network and the RCS terminal. Specifically, the MSRP mode may be adopted for file transmission, at this time, the IMS core network initiates an INVITE request for MSRP capability negotiation to the RCS terminal, the RCS terminal returns 200OK if agreeing to receive the file, after the MSRP capability negotiation is completed, an MSRP link is established, and then the application file is finally transmitted to the RCS terminal through the MSRP.
When the RCS user accesses the converged communication domain, the RCS user establishes a secure link with the access control function through IPSec, and the safety of signaling and bearing is ensured. In the invention, the existing file transfer function of RCS is reused, the existing signaling is simply modified, the greatest modification is to add application storage and downloading function on the network side, and strict check and control are needed to be carried out on the application source, which is essential for providing application downloading service. The changes can ensure that the RCS user can safely download the application under an established safe environment, the application file is not easy to be attacked and tampered maliciously, and the safety of the application downloaded by the user is greatly improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
