20130260780 | Method and apparatus for transforming working mode in cognitive radio system - The disclosure discloses a method and an apparatus for transforming a working mode in a Cognitive Radio (CR) system, which are used for solving the technical problem that a subsystem maliciously occupies the spectrum resources which are temporarily unused by other system in a system adopting a CR technology. In the disclosure, a network side measures the demand degree of each cell on borrowed spectrum and sets a conditions of enabling and disabling the CR working mode to determine whether to perform working mode transformation on the cell and specify a network allocation method for a mobile terminal in a corresponding working mode, so as to coordinate the allocation of the spectrum resources, and avoid the abuse of the borrowed spectrum resources; the CR working mode of the cell with low demand degree is disabled by the network side; the borrowed spectrum resources of the cell are released; and therefore, more borrowed spectrum resources are available to the other cells having a higher demand degree on the borrowed spectrum, and the overall performance of the system is improved. | 10-03-2013 |
20130310062 | SENSING AIDING METHOD AND SYSTEM FOR COGNITIVE RADIO - The disclosure discloses a sensing aiding method for cognitive radio. The method includes the following steps. a high level node transmits configuration information to a base station; the base station combines with a subordinate node of the base station to perform frequency spectrum sensing measurement, in which the subordinate node has sensing capability, and feeds back a result of the sensing measurement to the high level node; and the high level node formulates a corresponding WS allocation policy according to the received result of the sensing measurement. The disclosure also discloses a system. By the method and the system of the disclosure, the high level node transmits the configuration information to the base station; the base station performs the spectrum sensing measurement in combination with the subordinate node having the sensing capability of the base station in a designated frequency band and feeds the result of the sensing measurement back to the high level node; and the high level node formulates the corresponding WS allocation policy according to the result of the sensing measurement. Available white band resources are acquired; the probability of base station configuration failure is reduced, and the overhead caused by configuration failures is reduced. | 11-21-2013 |
20140120940 | Method and system of resource reconfiguration for cognitive-radio system - The disclosure provides a method and system of resource reconfiguration for a cognitive-radio system. The method includes that: a reconfiguration module of a wireless communication system acquires a reconfiguration command according to a received spectrum refarming indication or by monitoring a network condition of the wireless communication system ( | 05-01-2014 |
20140211654 | Spectrum resource reconfiguration method, device, and system - A spectrum resource reconfiguration method is disclosed. The method includes: after spectrum resource configuration is triggered, a spectrum resource configuration decision is generated, and spectrum resources are configured to a to-be-configured link according to the configuration decision. Also disclosed are a spectrum resource reconfiguration device and system for implementing the method. In the disclosure, a spectrum resource Database (DB) is set and stores currently available spectrum resources and used spectrum resources. In this way, when insufficient spectrum resources occur on some links or spectrum resources are unavailable, a system may configure corresponding spectrum resources to the links according to currently available spectrum resources, so that it is ensured that the links with insufficient spectrum resources have available resources, thereby ensuring development of as many services as possible. By means of the technical solution of the disclosure, the use of spectrum resources is more reasonable, all spectrum resources may be fully utilized instead of being limited to specific spectrum resources, thereby maximally utilizing the spectrum resources. | 07-31-2014 |
20140317465 | METHOD AND SYSTEM FOR TRANSMITTING LARGE OBJECT - The present disclosure provides a method for transmitting a large object, after a server establishes a session with a client, the method includes: the server divides a pre-transmitted large object into data blocks, and transmits one by one in sequence acquired data blocks and their sizes to the client; the client determines whether a received data block is transmitted successfully, if the received data block is transmitted successfully, the data block is saved, and a current data block transmission success message is returned to the server; if the received data block is not transmitted successfully, an end session request message or a re-transmitting current data block request message is returned to the server; and the server transmits the corresponding data block and its size or ends the session according to the received messages. The present disclosure further provides a system for transmitting a large object. When there is an error in transmitting a data block of a large object, the method and the system in the present disclosure process it in advance, thus saving bandwidth resources. | 10-23-2014 |
20150031376 | Radio system and spectrum resource reconfiguration method thereof - Disclose is a radio system and a spectrum resource reconfiguration method thereof. The method comprises: a Reconfigurable Base Station (RBS) divides subordinate nodes into groups according to attributes of the subordinate nodes, and sends a reconfiguration command to a subordinate node in a designated group, and the RBS and the subordinate node execute reconfiguration of spectrum resources according to the reconfiguration command; or, the RBS executes reconfiguration of spectrum resources according to the reconfiguration command; and a subordinate User Equipment (UE) accessing to a reconfigured RBS after interruption. By means of the present disclosure, the reconfiguration of spectrum resources of a cognitive radio system can be realized. | 01-29-2015 |
20150084773 | Mobile terminal and anti-stolen method thereof - A mobile terminal and an anti-theft method thereof are described. The anti-theft recognition module of the mobile terminal sends a security number acquisition instruction to a security number acquisition module after determining that the mobile terminal enters an anti-theft mode, the security number acquisition module automatically acquires a security number according to the security number acquisition instruction and sends the acquired security number to an anti-theft processing module, the anti-theft processing module gives an alarm according to the received security number to help the owner of the mobile terminal retrieve the mobile terminal or the information stored in the mobile terminal, thereby minimizing the loss of the owner of the mobile terminal and eliminating the potential safety hazard brought by the loss of the personal information stored in the mobile terminal. Moreover, the security number acquisition module automatically starts up to automatically acquire a security number after the anti-theft recognition module determines that the mobile terminal enters an anti-theft mode, thus avoiding the situation that no alarm is given after the mobile terminal is lost as the owner forgets to set an alarming function or makes an error in setting the alarming function and the situation that the giving of an alarm is failed as a manually set fixed number is out of service because of an overdue bill or not used any more. | 03-26-2015 |
