Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and technical solutions.

[0036] Aiming at situations such as leakage of user location information in the process of SIP signaling in the existing IMS network, an embodiment of the present invention provides a method for protecting specific user location information in the IMS network, see figure 1 As shown, it contains the following content:

[0037] 001. Obtain the target user request data in the IMS network session request message according to the SIP protocol field, the target user request data at least includes: the original identity location information of the target user;

[0038] 002. For the target user request data, construct corresponding virtual location data for covering the original identity location information of the target use...

Abstract

The invention belongs to the field of communication technology, and in particular relates to a method and equipment for protecting specific user location information in an IMS network. The implementation process is as follows: according to the SIP protocol field, the target user request data in the IMS network session request message is obtained; for the target user request data, Construct the corresponding virtual location data used to cover the original identity location information of the target user, and store the target user request data and the constructed corresponding virtual location data; use the virtual location data to replace the original identity location information in the target user request data, and store The replaced session request message is forwarded to the IMS network; the response data of the IMS network session request message is received, and the original identity location information in the response data is restored by the information cache module, and the restored response data is sent to the user terminal. The invention can effectively protect the network position of the specific target user, is safe and reliable, and can be widely applied to the specific target user who is sensitive to the privacy of the network position.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and equipment for protecting specific user location information in an IMS network. Background technique [0002] IP Multimedia Subsystem IMS is an internationally recognized standardized architecture first proposed by 3GPP. It was originally proposed to provide real-time multimedia services in mobile networks, but IMS also supports other access methods, such as PSTN , GSM, WCDMA, WLAN, etc. IMS is based on the IP network. It makes full use of the low cost, high bandwidth utilization and fast service provision of the IP network. It can flexibly deploy services on the IP network, and realize the collaboration between services, and develop converged services. The network is gradually becoming IP-based, and IMS will be an inevitable trend of future network development. IMS adopts SIP as the only session control protocol, which can provide users with multi...
