JVM GC对IMS HSS延迟分析

An Analysis of IMS HSS Delay Based on JVM GC

用户归属服务器(IMSHSS)是下一代通信网(NGN)核心网络IP多媒体子系统(IMS)中的主要用户数据库。IMSHSS中存储用户的配置文件,可执行用户的身份验证和授权,并提供对呼叫控制服务器的支持,另外也可提供用户位置信息等。根据移动网络中用户的数量、设备的容量和组织方式,IMS归属网络可以包含一个或多个HSS服务器。传统的移动网络,用户档案简单明了,用于身份认证、服务访问授权和基本服务配置。随着应用更加专注于个人的客户体验,用户档案在移动应用的业务逻辑中扮演的角色越来越重要,应用程序需要访问并能够操作数据。但是电信运营商或电信网络也已不是用户配置文件信息的唯一来源,还有需要被访问的增值用户信息,它超越了传统的网络边界,带来来自不同来源的信息,例如因特网存储库(新浪、搜狐等)和独立的应用数据存储(微信、QQ等)。用户档案信息正逐步成为电信运营商的无形数字资产。

The user home server (IMS HSS) is the main user database in IP multimedia subsystem (IMS), core network of the next generation communication network (NGN). The configuration file of the user is stored in IMS HSS, which can perform the authentication and authorization of the user identity, provide support for the call control server, and also provide the user's location information. Depending on the number of users, device capacity, and organization in the mobile network, the IMS home network can contain one or more HSS servers. Traditional mobile network, user files are simple and clear, used for identity authentication, service access authorization and basic service configuration. As applications become more focused on personal customer experiences, user files play a more and more important role in the business logic of mobile applications, and applications need to access and be able to manipulate data. However, telecom operators or telecom networks are no longer the only source of user profile information, and there is also value-added user information that needs to be accessed. It goes beyond the traditional network boundary and brings information from different sources, such as Internet repositories (Sina, Sohu, etc.) and independent application data storage (WeChat, QQ,etc.). User file information is gradually becoming the intangible digital asset of telecom operators.
