20160124936 | GRAMMAR COMPILING METHODS, SEMANTIC PARSING METHODS, DEVICES, COMPUTER STORAGE MEDIA, AND APPARATUSES - A corresponding grammar description file and a word category description file are defined based on a logical grammar by manifest language LGML according to a common sentence expression of a semantic meaning, in the grammar description file, the description for a common sentence is composed by operators, word categories, and functions, the word category description file is used to describe specific values for the word categories; the grammar description file and the word category description file are generated, with a reduction method according to a defined sequence, into a grammar tree for the grammar description file and word category trees for the word category description file; the word category trees are grafted at the positions of corresponding word categories on the grammar tree, forming a grammar tree for the semantic meaning, in this way, grammar compiling is accomplished. Based on the grammar tree of a semantic meaning with aforementioned ways, semantic parsing is carried out with whole-sentence matching, semantic mapping matching, or a combination of whole-sentence matching and semantic mapping matching. | 05-05-2016 |

20120134278 | Method, system and signaling gateway for enabling message intercommunication between GSM and CDMA - The disclosure discloses a method, a system and a signaling gateway for enabling message intercommunication between a Global System for Mobile Communications (GSM) network and a Code Division Multiple Access (CDMA) network. The method comprises: setting a GSM-CDMA (GC) signaling gateway in a service processor of a CDMA short message service center; during processing a message from the GSM network to the CDMA network, a GSM short message service center sending a mobile terminated request message to the GC signaling gateway, and the GC signaling gateway converting a GSM message into a CDMA message according to the mobile terminated request message and sending the converted CDMA message to a target CDMA subscriber; and, during processing a message from the CDMA network to the GSM network, a CDMA service processor converting a CDMA message into a GSM message and sending the converted GSM message to a target GSM subscriber. The disclosure enables service control more flexible and function extension more convenient by using the service processor to enable GC intercommunication via the NO. 7 signaling. | 05-31-2012 |

20120081103 | SIGNAL DETECTION CIRCUIT, METHOD AND SYSTEM - A signal detection circuit is provided, and includes a signal conversion module, a threshold control module, and a comparison module. The signal conversion module is configured to: convert a reference voltage signal into a reference current signal, and send the reference current signal to the threshold control module; convert a voltage signal to be detected into a current signal to be detected, and send the current signal to be detected to the comparison module. The threshold control module is configured to: generate a threshold current signal according the reference current signal, and send the threshold current signal to the comparison module; and receive a threshold control signal, and change magnitude of the threshold current signal according to the threshold control signal. The comparison module is configured to compare magnitude of the current signal to be detected with the magnitude of the threshold current signal, and output a comparison result. | 04-05-2012 |
