Embodiment Construction

[0036] In order to improve the scalability and flexibility of the IMS access domain security mechanism and meet different security requirements, the present invention configures one or more access domain security mechanisms on the network equipment of the IMS network, and according to the user's request message, Select to determine the access domain security mechanism used.

[0037] The network devices in the IMS network simultaneously support the implementation of multiple access domain security mechanisms, such as Figure 3A shown. The access domain security mechanism includes authentication methods adopted for users (such as Figure 3A Digest AKA, DigestMD5, etc.) and the type of secure channel that needs to be established between the user terminal and the Proxy-Call Session Control Function (P-CSCF) entity in the IMS network (such as Figure 3A IPSec in , TLS, etc.). One or more authentication methods and one or more security channel types can be configured on the HSS f...

Abstract

The invention discloses a unified method for accessing IP Multimedia Subsystem (IMS), which distributes one or more domain access securities for the network access or / and user IDs at network equipments of IMS network; the Network equipments choose one domain access security from the distributed ones based on the above requested information of user terminal, and the network equipments of access security handle referred request information with the chosen security.

Description

technical field [0001] The invention relates to security technology in the field of communication, in particular to a selection method of an IP multimedia subsystem (IMS) access domain security mechanism. Background technique [0002] As the core session control layer of fixed and mobile networks, IP Multimedia Subsystem (IMS) has become the focus of current industry discussions. Many IMS-related specifications are defined in the third generation mobile communication system (3G) and TISPAN standards, including network Architecture, interfaces, protocols and other aspects, among which security is an important aspect considered by 3G and TISPAN. The current specification divides the IMS network into the access domain and the network domain from the perspective of security, and defines the security specifications of the access domain and the network domain respectively. The security model of the IMS network is as follows: figure 1 shown. [0003] The call session control func...
