Perkembangan teknologi telekomunikasi menghasilkan berbagai peluang teknologi atau pun bisnis baru di berbagai bidang. Dengan munculnya teknologi 5G, muncul pula verticals seperti self-driving car, pembelajaran jarak jauh, dan berbagai kegiatan lainnya. Untuk mencapai kebutuhan dari verticals yang ada, 5G mengelompokkannya kedalam 3 kelompok usecase yaitu eMBB, mMTC, dan uRLLC dengan standar dan kebutuhannya masing-masing. Dengan adanya 3 kelompok usecase ini, muncul pula tantangan untuk menjalankan ketiga usecase ini dengan optimal. Teknologi network slicing memberikan terobosan baru untuk menjalankan ketiga usecase tersebut dalam satu jaringan fisik dengan membaginya menjadi beberapa jaringan virtual. Penelitian ini membahas salah satu skenario network slicing yaitu multi operator radio access network dimana sebuah sistem radio access network akan dicakupi oleh lebih dari satu operator dan membandingkannya terhadap network slicing dengan single operator pada satu sistem radio access network. Simulasi dibuat dan dikembangkan dengan menggunakan bahasa pemrograman python 3. Berdasarkan percobaan, didapatkan skenario multi operator menggunakan resource dengan lebih optimal dibuktikan dengan lebih tingginya nilai rasio client yang terkoneksi, lebih rendahnya nilai rasio blocking. Tetapi, nilai efisiensi bandwidth per client-nya sedikit lebih rendah. ......The development of telecommunications technology results in various technological opportunities or new business in various fields. With the advent of 5G technology, verticals have also emerged such as self-driving cars, distance learning, and various other activities. To achieve the needs of existing verticals, 5G groups them into 3 use cases groups namely eMBB, mMTC, and uRLLC to their respective standards and needs. With the existence of these 3 use cases groups, there are also challenges to running these three use cases optimally. Network slicing technology provides a new breakthrough to run the three use cases in one physical network by dividing it into several virtual networks. This study discusses one of the network slicing scenarios, namely a multi-operator radio access network where a radio access network system will be covered by more than one operator and compares it against a network slicing with a single operator on a radio access network system. Simulation is created and developed using python 3 programming language. Based on experiments, it is found that multi-operator scenarios use resources more optimally as evidenced by higher connected client ratio values, lower blocking ratio values. But, the bandwidth efficiency per client is slightly lower.

Network Surveillance mencakup pengamatan dan pengawasan jaringan, merupakan suatu penerapan pada sistem jaringan bergerak dalam memonitor, mengoperasikan dan maintenance suatu Network Element pada radio network untuk mempertahankan nilai indeks performansi, Key Performance Indicator (KPI), yang diinginkan oleh suatu operator seluler. Nilai indeks ini dapat dipertahankan dengan cara mengetahui kejadian-kejadian alarm pada Network Element, yang kemudian dapat dianalisa untuk mengkoreksi dan memperbaiki jika terjadi suatu kriteria yang tidak diinginkan. Oleh karena itu, melalui pelaksanaan studi skripsi ini diberitahukan apa itu Network Surveillance , aplikasi-aplikasi apa saja yang terdapat pada system OSS-RC ( Operation System Support for Radio and Core Network ) dan parameter counter pada Radio Access Network ( RAN ) yang dirasa cukup dalam mempertahankan nilai indeks performansi pada jaringan bergerak WCDMA.

Network Surveillance coverage on networking perception and observation, were one of implementation to mobile networking on monitoring, operation and maintenance of Network Element in radio network to maintaining performance index values, Key Performance Indicator (KPI), which requested by a seluler operator. This index values can be maintain by knowing the alarm events on the Network Element, which on the next stage will be analyze to perform correction and improvement if there is something happened that does not meet the criteria. Therefore, through this skripsi study implementation will be discuss what is Network Surveillance, what kind of aplications that implemented on OSS-RC (Operation System Support for Radio and Core Network) and others counter parameter on Radio Access Network (RAN) which can be maintain the performance index on WCDMA mobile network.

This Springerbreif introduces a threshold-based channel sparsification approach, and then, the sparsity is exploited for scalable channel training. Last but not least, this brief introduces two scalable cooperative signal detection algorithms in C-RANs. The authors wish to spur new research activities in the following important question: how to leverage the revolutionary architecture of C-RAN to attain unprecedented system capacity at an affordable cost and complexity. Cloud radio access network (C-RAN) is a novel mobile network architecture that has a lot of significance in future wireless networks like 5G. the high density of remote radio heads in C-RANs leads to severe scalability issues in terms of computational and implementation complexities. This Springerbrief undertakes a comprehensive study on scalable signal processing for C-RANs, where scalable means that the computational and implementation complexities do not grow rapidly with the network size.
