Problems solved by technology

The proprietary computing unit has a lower operating frequency, but has higher parallel computing capabilities, and lower overall performance and power consumption
[0005] After the user initiates registration, MMtel AS sends a UDR / PUR message to the HSS according to the IMPU to request downloading of user data and store the user data locally. When the user initiates a call, it directly reads the locally stored user data for call service processing. Storage is not securely protected and easily tampered with

Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] as attached figure 1 As shown, a key configurable system in the MMtel application server provides a secure and encrypted accelerated operating environment for the IP real-time multimedia call service in the IMS domain by building a heterogeneous accelerator card such as an FPGA accelerator chip on the MMtel application server. By setting the value range of the key handle in the background database on the MMtel application server, ...

Abstract

The invention discloses a key configurable system and method in an MMtel (MultiMedia Telephony) application server. The key configurable system is based on an IMS (IP Multimedia Subsystem) network architecture, and structurally comprises a home subscriber server (HSS), an MMtel application server and a serving-call session control function (S-CSCF) node which are sequentially connected, wherein the MMtel application server is internally configured with a heterogeneous acceleration card, and the heterogeneous acceleration card is used for performing encryption on registered user data in the IMS network architecture. Compared with the prior art, the key configurable system and method in the MMtel application server apply the heterogeneous acceleration card to the MMtel application server, a value range of a key handle is set in a background database on the MMtel, the flexible adaptability of generation of the key handle is ensured, and thus the randomness of generation of the key handle is guaranteed, thereby being high in practicability, wide in application range and easy to popularize.

Description

technical field [0001] The invention relates to the communication field, in particular to a key configuration system and method in an MMtel application server in the IMS field. Background technique [0002] In order to meet the needs of multimedia communication, the 3GPP organization introduced the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) on the basis of the original packet bearer network. IMS can not only provide users with traditional voice services, but also provide users with rich multimedia experience . The IMS includes a call control entity (CSCF, Call Session Control Function), a home subscriber server (HSS, Home Subscriber Server) and an application server (AS, Application Server). The CSCF includes S-CSCF (Serving-Call Session Control Function, serving CSCF), I-CSCF (Interrogating-Call Session Control Function, querying CSCF), and P-CSCF (Proxy-Call Session Control Function, proxy CSCF). The interface between AS and HSS is called Sh interface. AS ca...
