承载对象话统任务的创建及应用

话统即话务统计,又称话务测量、业务量测量、负荷测量、业务量统计,是指在交换局及其周围的电话网络上进行各种测量活动,为电话网络的量度、规划设计和运行管理提供可靠的数据依据。话统不仅是话务的测量和统计,还包括系统资源的测量、信令和接口的测量以及交换机内部运行情况的测量等内容。C&C08数字程控交换系统中根据测量子集的不同又分为十类话务统计任务,在宣钢867局企业专网中应用最多的是承载对象话统任务。

Quantum Dialogue by Using Non-Symmetric Quantum Channel

A protocol for quantum dialogue is proposed to exchange directly the communicator＇s secret messages by using a three-dimensional Bell state and a two-dimensional Bell state as quantum channel with quantum superdence coding, local collective unitary operations, and entanglement swapping. In this protocol, during the process of trans- mission of particles, the transmitted particles do not carry any secret messages and are transmitted only one time. The protocol has higher source capacity than protocols using symmetric two-dimensional states. The security is ensured by the unitary operations randomly performed on all checking groups before the particle sequence is transmitted and the application of entanglement swapping.

An rFC based service triggering algorithm for IMS network

To reduce the potential signaling traffic in IP multimedia subsystem （IMS）, the session establishment procedures were investigated. The serving call session eontrol function （S-CSCF） is the major bottleneck in IMS and the existing 3GPP service triggering algorithm （STA） based on initial filter eriteria （iFC） increases the end-to-end session setup delay remarkably. To reduce the session setup delay and improve the system performanee, a SIP response message based filter criteria （rFC） was proposed. Based on the rFC, a SIP response message based STA （RSTA） was further proposed. The modeling and theoretical analysis of 3GPP STA and RSTA were presented. Simulation results show that, compared with 3GPP STA, the RSTA can avoid the additional signaling traffie load of the S-CSCF and application server （AS） effectively, reduce the session setup delay eonsiderably, increase the throughput of the S-CSCF and improve the quality of service （QoS） of IMS network.

Chinese spoken language understanding in SHTQS

Spoken dialogue systems are an active research field with wide applications. But the differences in the Chinese spoken dialogue system are not as distinct as that of English. In Chinese spoken dialogues, there are many language phenomena. Firstly, most utterances are ill-formed. Secondly, ellipsis, anaphora and negation are also widely used in Chinese spoken dialogue. Determining how to extract semantic information from incomplete sentences and resolve negation, anaphora and ellipsis is crucial. SHTQS (Shanghai Transportation Query System) is an intelligent telephone-based spoken dialogue system providing information about the best route between any two sites in Shanghai. After a brief description of the system, the natural language processing is emphasized. Speech recognition sentences unavoidably contain errors. In language sequence processing procedures, these errors can be easily passed to the later parts and take on a ripple effect. To detect and recover these from errors as early as possible, language-processing strategies are specially considered. For errors resulting from divided words in speech recognition, segmentation and POS Tagging approaches that can rectify these errors are designed. Since most of the inquiry utterances are ill-formed and negation, anaphora and ellipsis are common language phenomena, the language understanding must be adequately adaptive. So, a partial syntactic parsing scheme is adopted and a chart algorithm is used. The parser is based on unification grammar. The semantic frame that extracts from the best arc set of the chart is used to represent the meaning of sentences. The negation, anaphora and ellipsis are also analyzed and corresponding processing approaches are presented. The accuracy of the language processing part is 88.39% and the testing result shows that the language processing strategies are rational and effective.

Joint Channel Estimation and Decoding Design for 5G-Enabled V2V Channel

This paper addresses the problem of channel estimation in 5G-enabled vehicular-to-vehicular(V2V) channels with high-mobility environments and non-stationary feature. Considering orthogonal frequency division multiplexing(OFDM) system, we perform extended Kalman filter(EKF) for channel estimation in conjunction with Iterative Detector & Decoder(IDD) at the receiver to improve the estimation accuracy. The EKF is proposed for jointly estimating the channel frequency response and the time-varying time correlation coefficients. And the IDD structure is adopted to reduce the estimation errors in EKF. The simulation results show that, compared with traditional methods, the proposed method effectively promotes the system performance.

The Case for Presupposition： On Kripke＇s Anaphoric Account

According to Kripke, traditional approaches to presupposition and anaphora do not work in some compound sentences because traditionally, they have been thought to assign presuppositions to each clause in isolation. I agree with this criticism, but also think that context is required in order to determine the presupposition included in a complex sentence. To show the context role in fixing the utterance truth-conditions in those cases, this paper introduces the Kripkean anaphoric account on presuppositions （section 2）, and then criticizes this approach because it is very restrictive （section 3）. The paper concludes that to solve those difficulties, one should appeal to a two-dimensional framework, including a new parameter that focuses on the sentence according to the concrete features of the context： the speaker＇s point of view （section 4）.

Studies on a Korean Buddhism Community： Searching for Unity Through Open Discourse

Korean Buddhism community has tried to develop its traditions as well as maintaining them through open discussion. Some current incidents, such as the election of the director for the headquarters of the Chogye Order, controversial issues on a prime minster nominee, and the difference between practicing and learning which has been discussed in Buddhist Academia, have generated a new wave in the Korean Buddhism world. Many religious practices which have infiltrated Korean society, including Catholicism and Christianity, have been indigenized to become a unique religious form combined with Korean Shamanism, through which individuals want to achieve personal happiness or material prosperity. Buddhism has been through the same process. Additionally, Buddhism has played a leading role in teaching the public of Korea for a long time and has become a model role for solving national crises. Currently, the Korean Buddhism world has tried to be reborn as a religion that keeps these beneficial traditions in Korea, and the Korean Buddhism can play a positive role in every aspect of culture, politics, and society. Further, the Korean Buddhism is looking for ways to influence Korean society through open discussions. This paper brings out issues that Korean Buddhism faces and presents the solutions to solve those problems.

Non-traditional Dialogues between Thoughts

The article considers a new and non-traditional form of dialogue. Calling it a ＂spiritual dialogue＂ or the intersection of thoughts, the author comments on this type of dialogue as a basis for interreligious, intercultural and intercivilizational dialogues, seeing it as their main motive force. In this study, firstly, traditional and non-traditional dialogues are compared and indicate their specific features on the basis of the work of the Eastern and the West thinkers. Then, the nontraditional dialogue has been considered in the context of modern information chaos. The last section of the article is devoted to the analysis of the basic principles of non-traditional dialogue, emphasizing the role of language. The conclusion of the article once again highlights the importance of non-traditional dialogue that starts in the inner world of the human being, which gives him a possibility to observe an object from two viewpoints and merge and these different views in the mind.
