A key challenge is striking the balance between cost and reliability, as these are inherently at odds; the network lack of redundant deployment might not be able to obtain high reliability. We propose a novel method to this challenge that draws inspiration from 5G-advanced and 6G evolution. The Network Data Analytics Function (NWDAF) provides a means for intelligent control and scheduling based on the ability of data analysis. Our method enables Home Subscriber Server(HSS) as the backup of the Unified Data Management(UDM) by automated transferring in real time, when NWDAF detects all UDMs failing. The mechanism and procedures of automated disaster backup and recovery are described in detail. Finally, the effectiveness of the proposed method is analyzed by Fault Tree Analysis(FTA) and probability theory with qualitative and quantitative evaluation.","PeriodicalId":155272,"journal":{"name":"2022 International Communication Engineering and Cloud Computing Conference (CECCC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127281021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, long short-term memory (LSTM) is introduced in this task with novelty and efficiency. With the advantage of truncating the gradient harmlessly, LSTM is able to connect thousands of time steps by forcing a constant error flow within special cells contains constant error carousels. The multiplication gate unit learns open and close access to a constant stream of errors. In comparison with recurrent cascade correlation, real-time recurrent learning, and chunking of neural sequence, LSTM brings about more successful results and has a short learning time. LSTM is also able to solve complicated, artificially long-lag tasks. Based on its superiority, LSTM network serves as a useful tool in time series forecasting. We use the LSTM network to forecast the cases of varicella in the future. And the current LSTM network is optimized to increase the efficiency. Finally, the training time is decreased and the accuracy of trained network is increased simultaneously when the quantity of hidden units is changed from 200 to 100.","PeriodicalId":155272,"journal":{"name":"2022 International Communication Engineering and Cloud Computing Conference (CECCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tamed spread spectrum communication system is developed on the basis of it. Most of the literature does not distinguish this spread spectrum technique from direct spread spectrum. In this paper, the performance of tamed spread spectrum with single -frequency interference is analyzed and simulated compared with direct spread spectrum. The conclusion is drawn that the tamed spread spectrum technology has a strong ability to resist random noise interference, but for human interference, its performance is seriously declined. The FPGA implementation method of tamed spread spectrum communication system is mainly studied as well.","PeriodicalId":155272,"journal":{"name":"2022 International Communication Engineering and Cloud Computing Conference (CECCC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130386699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
