Embodiment Construction

[0026] Fig. 2 is a simulation structure diagram of the embodiment of the present invention. The figure includes a script-based simulation engine, a simulator located on the above-mentioned script-based simulation engine and a compatibility testing component located on the above-mentioned script-based simulation engine. The script-based simulation engine includes a Java virtual machine, a protocol layer on the Java virtual machine, and a script execution engine on the protocol layer.

[0027]The above-mentioned Java virtual machine JVM (Java Virtual Machine) is a fictitious computer, which is realized by simulating various computer functions on an actual computer. The Java virtual machine has its own complete hardware architecture, such as processors, stacks, registers, etc., and also has a corresponding instruction system. The Java virtual machine shields the information related to the specific operating system platform, so that the Java program can run without modification o...

Description

technical field [0001] The invention relates to a simulation method in the communication field, in particular to a method for simulating an IP-based multimedia subsystem. Background technique [0002] In 2002, the 3rd Generation Partnership Project (3GPP) proposed the IP-based multimedia subsystem ( The concept of IP Multimedia Subsystem; IMS). IMS uses the Session Initiation Protocol (SIP) based on the Internet Engineering Task Force (IETF) to provide a carrier-class Internet Protocol (Internet Protocol; IP)-based service network for telecom operators. It has the reliability, manageability, operability and profitability of the traditional telecommunication network, and at the same time has the flexibility of the Internet and the ability to widely support multimedia services. [0003] FIG. 1 is a schematic structural diagram of an IMS system. The IMS generally includes functional entities such as a Call Session Control Function (Call Session Control Function; CSCF), a Hom...
