20080205282 | METHOD FOR PROTECTING THE SERVICE FLOW AND A NETWORK DEVICE - A method for protecting the service flow is provided, wherein a back path is preset between the source node and the destination entity, the method includes steps: A, the source node switches the service flow to the backup path and transmits the service flow to the destination entity through the backup path, at the same time, the source node computes a hypo-excellent path by the route algorithm, and compares the hypo-excellent path with the backup path, if the hypo-excellent path is more excellent than the backup path, then implements the step B, if not, ends the program. B, the source node switches the service flow to the hypo-excellent path and transmits the service flow to the destination entity through the hypo-excellent path. A network device implementing the method for protecting the service flow is also provided. The method for protecting the service flow in the invention has the ability that the fast fault restoration. | 08-28-2008 |
20090271567 | METHODS FOR MANAGING BLOCKS IN FLASH MEMORIES - A method for managing blocks in a flash memory is provided, which includes dynamic and static block managing methods. In the dynamic block managing method, a blank block is selected as a swap block for write operation. During each write operation, new data and/or original data in an object block to be operated are written into the swap block, and the object block is erased. Then, a logical address of the object block is changed to be a logical address of the swap block, so that the object block served as the swap block for a next write operation. In the static block managing method, a variable seed parameter is set. Different values of the seed parameter are each associated with a logical address of a respective flash memory block. When the value of the seed parameter varies, data in the flash memory block and the swap block associated to the value of the seed parameter are exchanged, so that the flash memory block associated to the value of the seed parameter becomes the swap block for the next write operation. | 10-29-2009 |
20100100668 | CONTROL METHOD FOR LOGICAL STRIPS BASED ON MULTI-CHANNEL SOLID-STATE NON-VOLATILE STORAGE DEVICE - A control method for logical strips based on a multi-channel solid-state non-volatile storage device is provided. The method includes the following processing steps. In Step 1, a storage space of every channel is partitioned into a plurality of storage units of equal size. In Step 2, at least one logical strip is set by which the storage units with discrete physical addresses across a plurality of channels are organized into a continuous logical space. In Step 3, during data reading/writing operation, the data is divided according to a size of each local strip, the divided data is mapped to the storage units of every channel, and a parallel reading/writing operation is performed across the channels. This method may increase the efficiency of reading and writing operations of the storage device and prolong the operating life span of the device. | 04-22-2010 |
20100100669 | SELF-ADAPTIVE CONTROL METHOD FOR LOGICAL STRIPS BASED ON MULTI-CHANNEL SOLID-STATE NON-VOLATILE STORAGE DEVICE - A self-adaptive control method for logical strips based on a multi-channel solid-state non-volatile storage device is provided. The method includes the following steps. Storage space of every channel is divided into a plurality of storage units of equal size. At least one logical strip is set by which the storage units with discrete physical addresses across the channels are organized into a continuous logical space, and a logical strip variable is set for determining the storage units organized by the logical strip. Historical operation information of the storage device is obtained statistically, and the logical strip variable is dynamically adjusted according to the obtained operation information. During data interaction, the data is divided according to the logical strip variable, the divided data is mapped to the storage units of every channel, and parallel reading and writing operations are performed among the channels. | 04-22-2010 |

20120137104 | ALLOCATION METHOD AND APPARATUS OF MODERATE MEMORY - An allocation method comprises: partitioning moderate memory into a plurality of physical memory pages having predetermined page size according to the predetermined page size; scanning the moderate memory using the predetermined page size and recording the physical address and damage degree of each physical memory page; obtaining the allocation information of the physical memory pages when a memory request is received and allocating physical memory to the request based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information. A moderate memory is scanned and the physical address and damage degree of each physical memory page are recorded, then the physical memory is allocated based on the recorded physical address and damage degree of each physical memory page and the obtained allocation information. | 05-31-2012 |
20140269617 | METHOD FOR MODIFYING MULTIPLE INPUT MULTIPLE OUTPUT MODE ACROSS RADIO NETWORK CONTROLLERS - A method for modifying Multiple Input Multiple Output (MIMO) mode across Radio Network Controllers (RNCs) is provided by the present disclosure. In the method of the present disclosure, a Serving RNC (SRNC) transmits a request message to a Drift RNC (DRNC), wherein the request message requests the DRNC to set a radio link for a mobile equipment in a cell controlled by the DRNC, and the DRNC feeds back a response message to the SRNC based on the capability of the DRNC and the cell controlled by the DRNC, wherein the response message contains the element used for configuring the radio link in the non-MIMO mode. As a result, when the DRNC and the cell controlled by the DRNC support the MIMO mode, the SRNC configures the radio link to be in the MIMO mode for the mobile equipment, and when the DRNC and the cell controlled by the DRNC do not support the MIMO mode, the SRNC configures the radio link to be in the non-MIMO mode for the mobile equipment. Therefore, a mobile equipment handover or a radio link reconfiguration is completed, and the success rate of the handover or the configuration is improved. | 09-18-2014 |
20150092579 | Drive Test Minimization Method and Device for Obtaining Time Delay - A method, device and system for controlling assistant information of user equipment are disclosed. The field of wireless communication technology is related, and the problem is solved that the system efficiency is reduced, for UE reports the assistant information inappropriately.
