    Abstract: A method and system provide seamless, wireless telecommunication service to customers that move between disparate networks that use different protocols. A Universal Location Service Register (ULSR) communicates and provides mobility management and authentication functions across networks that use different protocols. Instead of associating each MSC with an HLR and an AuC that uses the same messaging protocol as the MSC, each MSC communicates with the ULSR for user information. The ULSR communicates with the MSCs in each network serviced by the ULSR in accordance with the protocol of that network. The ULSR stores user profiles that may include the identity of the user, authentication information for the user's mobile phone, a list of networks the user is authorized to access, and the identity of the MSC at which the user is currently registered.

    Abstract: The present invention provides a system and method for creating virtualized storage in a storage area network using distributed table-driven input/output mapping. The present invention distributes the virtualization mapping in multiple parallel, mapping agents that are separate from a controller. This allows the performance-sensitive mapping process to be parallelized and distributed optimally for performance, while the control of the mapping may be located in a controller chosen for optimal cost, management, and other implementation practicalities. The mapping agents store the virtual mapping tables in volatile memory, substantially reducing the cost and complexity of implementing the mapping agents. The controller is responsible for persistent storage of mapping tables, thereby consolidating the costs and management for persistent mapping table storage in a single component. Distributed virtualization also allows the controller to manage multiple virtual disks used by multiple host systems, and allows a single virtual disk to be shared by multiple host systems. The mapping agents preferably do not interact only with other mapping agents, thereby improving the scalability of the virtual storage system and the virtual storage system's tolerance of component failures.

    Abstract translation: 本发明提供一种使用分布式表驱动输入/输出映射在存储区域网络中创建虚拟化存储的系统和方法。 本发明将虚拟化映射分配在与控制器分离的多个并行映射代理中。 这允许性能敏感的映射过程被并行化并且最佳地分布在性能上，而映射的控制可以位于选择用于最佳成本，管理和其他实现实用性的控制器中。 映射代理将虚拟映射表存储在易失性存储器中，大大降低了实现映射代理的成本和复杂性。 控制器负责映射表的持久存储，从而整合单个组件中持久映射表存储的成本和管理。 分布式虚拟化还允许控制器管理多个主机系统使用的多个虚拟磁盘，并允许单个虚拟磁盘由多个主机系统共享。 映射代理优选地不与其他映射代理交互，从而提高虚拟存储系统的可扩展性和虚拟存储系统对组件故障的容限。
