Huawei Assigned Four Patents

Disaster recovery of IMS
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,661,028) developed by Liang, Feng, Shen, Linfei, Shenzhen, China, and Shi, Shufeng, Xi’an, China, for a “method, apparatus, and system for disaster recovery of IMS.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method, apparatus, and system for disaster recovery of an IP Multimedia Subsystem, (IMS) are provided. The method includes: triggering a redundant Call Session Control Function, (CSCF), obtaining, by the redundant CSCF, user backup data of registered IMS Private User Identities, (IMPIs) that are associated with IMPUs and user service configuration data of IMS Public User Identities, (IMPUs) in an IMS subscription from a network storage entity of a user, and recovering, by the redundant CSCF, a corresponding service according to the obtained user backup data of the registered IMPIs and user service configuration data of the IMPUs in the IMS subscription. With the present invention, the one-IMPU multi-IMPI, one-IMPI multi-IMPU, or multi-IMPI multi-IMPU service can be recovered, and this enables the user to have better service continuity experiences.“

The patent application was filed on January 13, 2012 (13/350,654).

Magnetic track storage unit
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,653,178) developed by Lin, Yinyin, Shanghai, China, Wei, Zhulin, Zhao, Junfeng, Shenzhen, China, Yang, Wei, Hangzhou, China, Fu, Yarong, and Yang, Kai, Shanghai, China, for a “magnetic track storage unit, memory, and method for controlling magnetic track storage unit.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage device, a memory, and a method for controlling a storage device, where the storage device includes a comb-shaped magnetic track, a first drive circuit, a second drive circuit, a first drive port, and a second drive port, where the comb-shaped magnetic track includes a first storage area, a second storage area, and a comb handle, and the first storage area and the second storage area include more than two memory bars.“

The patent application was filed on April 20, 2016 (15/133,452).

Information storage
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,653,099) developed by Lin, Yinyin, Fu, Yarong, Yang, Kai, Shanghai, China, Yang, Wei, Hangzhou, China, Wang, Yuangang, and Zhao, Junfeng, Shenzhen, China, for a “information storage apparatus and method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An information storage apparatus includes a magnetic track, a writer, and a reader, where the magnetic track includes a number of magnetic domains. Each magnetic domain is divided into at least two magnetic regions, and the writer is disposed on the magnetic track, and configured to write information to the at least two magnetic regions of each magnetic domain. The reader, disposed on the magnetic track, is configured to read the written information from the at least two magnetic regions. Therefore, multiple pieces of valid information are written to one magnetic domain of the magnetic track, thereby increasing storage density of the magnetic track, and expanding a storage capacity of the storage apparatus.“

The patent application was filed on March 23, 2016 (15/078,594).

Operation method for storage system
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,639,588) developed by Cheng, Shi, Shenzhen, China, for a “operation method and apparatus for data storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An operation method and apparatus for a data storage system are provided, which relate to the field of data storage and enhance efficiency of a read operation on distributed stored data. The method includes: receiving, by a data node, a data operation message, where the data operation message carries a data operation type and a data object of an operation, querying a state parameter of the data object, where the state parameter is allocated to the data node by a management node, and is used to indicate an update state of the data object, and the update state includes a synchronous state, a semi-synchronous state and an asynchronous state, and if the state parameter is the synchronous state and the operation type is a read operation, reading the data object stored by the data node. Embodiments of the invention are used to operate data in a distributed data storage system.“

The patent application was filed on November 29, 2013 (14/093,124).
