    • A system and method for enabling sensitive authentication information to be under the control of the service provider and transmitting only non-sensitive authentication information to the AC, for providing a secure technique for generating sensitive authentication information and for securely transmitting to and storing the information in the mobile system (MS) and a storage device controlled by the service provider, and for enabling a mobile station to utilize features supported by the visited system even if the MS home system does not support the feature. The present invention utilizes a secure authentication center (SAC) and a secure A-key management system (SAMS) to perform authentication. The SAC can be positioned locally in a home system, or it can be centrally located, for example, between systems. The SAC can be connected to many SAMS. Each SAMS stores sensitive authentication information for a group of MS's. During authentication, the SAC generates a request signal to the appropriate SAMS which generates a unique signal based upon the secret authentication data and other data stored therein. However, the sensitive authentication data is not sent to the SAC. The SAC performs authentication using the unique signal transmitted by the SAMS.
    • 一种用于使敏感认证信息处于服务提供商的控制下并且仅将非敏感认证信息发送到AC的系统和方法,用于提供用于产生敏感认证信息的安全技术,并且用于安全地传送和存储信息 移动系统(MS)和由服务提供商控制的存储设备,并且即使MS家庭系统不支持该特征,也能够使移动站利用所访问系统支持的特征。 本发明利用安全认证中心(SAC)和安全A密钥管理系统(SAMS)进行认证。 SAC可以位于本地系统的本地,也可以位于中央位置,例如系统之间。 SAC可以连接到许多SAMS。 每个SAMS存储一组MS的敏感认证信息。 在认证期间,SAC根据秘密认证数据和存储在其中的其他数据,向适当的SAMS生成请求信号,该SAMS生成唯一信号。 但是,敏感认证数据不会发送到SAC。 SAC使用SAMS发送的唯一信号来执行认证。

    • Conformance with established standards and interoperability between products in an integrated services digital network (ISDN) system defined by a layered hierarchy of interrelated protocols is ascertained by remotely testing the protocols between a tester in a local testing centre and a system under test located at a geographically removed site. The protocols tested relate to the first three layers of the system which are concerned mainly with the establishment, holding and release of a telecommunications path. Cost effectiveness in product testing is achieved by accessing both the tester and the system under test and communicating test procedures between the local and remote sites over a packet switching network to support testing at the remote site. Communications over a virtual circuit in the network are established between a pair of remote ISDN test access interfaces, one located at each site. A communications path from a test access interface and its corresponding local tester or system under test is provided by an ISDN interface. Under software control by a computer at each site, the test access interfaces function individually to split the corresponding ISDN interface so that the network may be inserted therebetween to link the tester with the system under test.
    • 通过远程测试本地测试中心的测试人员和位于地理位置的被测系统之间的协议来确定符合已建立的标准和由相关协议分层层次结构定义的综合业务数字网(ISDN)系统中的产品之间的互操作性 删除的网站。 测试的协议与系统的前三层相关,主要涉及电信路径的建立,保持和释放。 产品测试的成本效益是通过访问测试人员和受测系统,并通过分组交换网络在本地和远程站点之间传送测试程序来实现的,以支持远程站点的测试。 在一对远程ISDN测试访问接口之间建立网络中虚拟电路的通信,一个位于每个站点。 来自测试接入接口及其对应的本地测试仪或被测系统的通信路径由ISDN接口提供。 在每个站点的计算机进行软件控制的情况下,测试访问接口单独进行功能分割,以便将相应的ISDN接口分开,以便将网络插入其间,将测试仪连接到被测系统。

    • A system and method is used to characterize a user with properties, such as location in relation to established geo-fences, speed of traverse, projected traveling time required for a particular distance, etc. Those properties contribute to yielding a quantitative result in the calculated lead time period prior to the user arriving at a monitored space, including but not limited to a rented room in a hotel, and a house. The method uses the user's arrival time to estimate the setback temperature, which is the indoor temperature of a monitored space maintained during unattended time periods. The method also uses the user's arrival time to estimate the heated water volume to be provided, as well as, to house watch other property management interests.
