20100205587 | METHOD, DEVICE AND SYSTEM FOR REALIZING KERNEL ONLINE PATCHING - A method, a device, and a system for realizing kernel online patching are provided. The method includes loading a pre-generated patch file in an operating system, setting a first breakpoint at an execution start position of the primitive function when a system thread executes the primitive function and a breakpoint exception occurs during the thread execution process due to the first breakpoint, modifying a returning execution address of the first breakpoint into the destination address of the patch function corresponding to the primitive function according to the first corresponding relation, and removing the first breakpoint. The kernel online patching implementation has a small impact on the normal operation of the operating system. The patch function becomes valid without restarting the operating system, thereby satisfying the high reliability requirements of carrier-class products. | 08-12-2010 |
20120102476 | METHOD, DEVICE AND SYSTEM FOR ACTIVATING ON-LINE PATCH - Embodiments of the present invention provide a method, a device and a system for activating an on-line patch. The method comprises: positioning an address of a patch function and an entry address of a to-be-patched function; writing, in a middle segment, a long-jump instruction for jumping to the patch function based on the address of the patch function and the entry address of the to-be-patched function, where the middle segment is a storage space, which is located before or after the entry position of the to-be-patched function and can at least store one long-jump instruction; and modifying an instruction at the entry position of the to-be-patched function to a short-jump instruction for jumping to the middle segment, so as to jump to the middle segment after the short jump instruction is executed, and then to jump to and execute the patch function through that instructions in the middle segment are executed. | 04-26-2012 |
20120257632 | METHOD, COMBINER AND SYSTEM FOR TRANSMITTING SIGNALS - Methods and apparatus are provided for receiving AISG protocol signals sent by one or more local devices and adding corresponding labels to the AISG protocol signals, where the labels are used to identify mapping relationships between the local devices that send the AISG protocol signals and peer devices. The AISG protocol signals to which the labels have been added are packed into data packet and sent to a peer combiner through a shared feeder. The peer combiner unpacks the data packet and sends the AISG protocol signals to corresponding peer devices according to the labels added to the AISG protocol signals. | 10-11-2012 |
20140115603 | METHOD, APPARATUS, AND SYSTEM FOR SCHEDULING PROCESSOR CORE IN MULTIPROCESSOR CORE SYSTEM - The present invention discloses a method, an apparatus, and a system for scheduling a processor core in a multiprocessor core system, which relate to the field of multiprocessor core systems, and can meet the demand for real-time network I/O processing, thereby improving the efficiency of the multiprocessor core system. The method for scheduling a processor core in a multiprocessor core system includes: obtaining, in the running process of the multiprocessor core system, a first control parameter, a second control parameter, a third control parameter, and a fourth control parameter; transferring a packet of a data flow that enters the multiprocessor core system to an idle processor core for processing based on the first control parameter, the second control parameter, and the third control parameter; and switching over the processor core in the multiprocessor core system between an interruption mode and a polling mode based on the fourth control parameter. | 04-24-2014 |
20140237462 | METHOD AND SYSTEM FOR SOFTWARE UPGRADE - A method of upgrading an application installed on a mobile device is performed at a server. The method includes: determining a current version of the application installed on the mobile device and a new version of the application to be installed on the mobile device; generating a binary incremental package by comparing the current version of the application and the new version of the application using a binary file difference tool; in response to a upgrade request from the mobile device: pushing the binary incremental package to the mobile device through a wireless network; and receiving an application upgrade confirmation message from the mobile device. The mobile device is configured to reconstruct a version of the application and replace the current version of the application with the new version of the application using the reconstructed version of the application. | 08-21-2014 |
20150117311 | SINGLE-PDP DUAL STACK SERIAL DIALING METHOD AND SYSTEM - a method and system for single-PDP dual-stack serial is provided. A mobile terminal sets a single-PDP dual-stack serial dialing parameter according to a parameter setting command transmitted by a host; then the mobile terminal initiates a PDP activation request to a mobile communication network according to a first dialing instruction transmitted by the host and the configured single-PDP dual-stack serial dialing parameter, acquires activation response information fed back by the mobile communication network, generates dialing response information according to the activation response information, and feeds back the dialing response information to the host, wherein the dialing response information includes cause reference information; and after receiving the dialing response information, the host can acquire a specific condition of the current mobile network according to the cause reference information included in the dialing response information to determine a dialing mode. Unnecessary dialing processing and a dialing failure can be avoided, the condition of unnecessarily returning to dual-PDP dual-stack dialing can be avoided, a dialing flow can be simplified, dialing efficiency can be improved, and a utilization rate of a system resource can be increased. | 04-30-2015 |
20150180823 | System and data card for stateless automatic configuration of IPv6 address and method for implementing the same - Disclosed are a system and data card for stateless automatic configuration of an IPv6 address and the method for implementing the same, and the method includes: an IPv6 address configuration way of a data card is set and stored according to an IPv6 address allocation strategy of a current network, after successful establishment of an IPv6 dialup connection and reception of a router advertisement request message transmitted by a terminal for acquiring a prefix address, the data card determines the set IPv6 address allocation way, and when the set IPv6 address allocation way is a static configuration way, a router advertisement response message is discarded and a valid IPv6 global unicast address is reported to the terminal. By means of the system, data card and method, it is possible to solve a problem that data transmission can not be normally performed by an existing data card implementing dialup in an Ethernet link way when interface identifiers are allocated by a network. | 06-25-2015 |
20150181431 | Method and Device for Controlling A Data Card APN Locking State, and Data Card - A method and apparatus for controlling an APN locking state of a data card, a data card and a method for dialing using the data card. The control method includes: after the data card receives an APN parameter setting instruction which is an administrator user instruction, modifying a current APN locking state of the data card according to a locking state parameter carried in the instruction, and writing an APN parameter carried in the instruction and the APN locking state into a nonvolatile storage area; and the dialing method includes: when a dialing connection is established, PC side dialing software querying the APN locking state of the data card, and if the data card is currently in a locked state, only using an APN parameter set in a default PDP Profile to establish the dialing connection. | 06-25-2015 |
