Pada Jaringan Operator PT. Excelcomindo Pratama, khususnya area Jabodetabek, memiliki beban trafik MSC yang tidak merata. Skripsi ini membahas optimasi MSC dengan menerepakan sistem TS 23.236 sebagai salah satu solusi untuk meratakan beban pada MSC. Dalam perencanaan MSC pool dengan konsep 3GPP TS 23.236 yang diperhatikan adalah struktur TMSI dan NRI. Jumlah identifikasi TMSI menjadi acuan untuk menentukan jumlah subscriber aktif yang berada pada area MSC Pool. Sedangkan NRI berfungsi menentukan untuk jumlah node. Area Jabodetabek dimana terdapat 31 BSC, 18 MGw, dan 10 MSC-Server, dalam skripsi ini dibagi menjadi 3 service pool area. Dari pembagian ini menyebabkan daya tampung seluruh area pool untuk Jabodetabek area adalah 19,996,000 subscriber aktif. Pembagian area pool tersebut adalah Pool 1, Jakarta yang mengarah ke Tanggerang dan serang, Pool 2, Jakarta yang mengarah kearah Bekasi dan Cikampek, Pool 3, Jakarta yang mengarah kearah Depok dan Bogor. Dari perencanaan didapatkan perhitungan bahwa beban yang akan diterima dengan mengaplikasikan MSC Pool adalah 50 ~ 60 %. Dari hasil simulasi didapatkan bahwa MS akan terdistribusi secara merata ke seluruh MSC/VLR, dengan maksimum MSC/VLR adalah 800.000 subscriber. MS akan dialokasikan ke MSC/VLR secara berurutan. Trafik yang dihasilkan oleh BSC terdistribusi secara porposional berdasarkan kapasitas trunk yang di sediakan antar BSC ? MGw. Jika ternyata kapasitas trafik melebih kapasitas trunk yang ada, maka terdapat trafik yang hilang atau terbuang.

Cellular operator network, PT Excelcomindo Pratama, special in Jabodetabek area, have unbalance traffic load at MSC. This paper studying on optimize core network with 3GPP TS 23.236 application, as one of solution to balancing load MSC as core network. In the plan MSC pool with 3GPP TS 23.236 concept which is attention on TMSI and NRI structure. Amount identifies TMSI become reference to determine the amount of active subscriber which resides in MSC Pool area. While function NRI determine to the amount of MSC node. Area Jabodetabek where there are 31 BSC, 18 MGW, and 10 MSC-SERVER, in this paper is divided to become 3 area pool services. From this division causes accommodate all pool area for the Jabodetabek of area is 19,996,000 active subscribe. Division of the pool area is Pool 1, Jakarta which flange to Tanggerang and Serang, Pool 2, Jakarta which flange toward Bekasi and Cikampek, Pool 3, Jakarta which flange toward Depok and Bogor. From planning by calculation that burden to be accepted with MSC Pool application is 50 ~ 60 %. From result of simulation, MS distribution will flattened to all MSC/VLR, maximum MSC/VLR is 800.000 subscribers. Allocation MS to MSC/VLR alternately. Traffic which yielding by BSC, distribute by porposional pursuant to trunk capacities which providing between BSC - MGW. If in the reality traffic capacities more existing trunk capacities, hence there are missing traffic.

[ABSTRAK
Kebutuhan akan layanan data pada jaringan telekomunikasi terus meningkat, jumlah trafik data setiap tahun selalu bertambah sedangkan trafik voice cenderung sudah jenuh. Teknologi 4G LTE (Generasi ke-empat Long Term Evolution) sebagai teknologi jaringan telekomunikasi terbaru dari 3GPP (Thrid Generation Pathnership Project) mampu memberikan kecepatan dan kapasitas lebih baik dari teknologi sebelumnya. Implementasi 4G LTE ini menjawab tantangan trend kebutuhan akan layanan data yang terus meningkat. Dalam proses implementasinya terdapat 2 tantangan besar yaitu terbatasnya lebar pita frekuensi di 1800 Mhz dikarenakan harus berbagi dengan sistem eksisting 2G DCS 1800 Mhz, dan kondisi demografi Indonesia yang bervariasi. Model dibangun dengan mengkombinasikan tipe area dengan lebar pita yang digunakan mulai dari 3 Mhz, 5 Mhz, 10 Mhz, 15 Mhz dan 20 Mhz. Dengan melakukan simulasi pada berbagai tipe area di Jabodetabek dan berbagai lebar pita frekuensi dihasilkan lebar pita yang berbeda pada masing-masing area berdasarkan aspek teknis (coverage dan kapasitas) dan kelayakan ekonomi yang diharapkan.

ABSTRACT The need for data services in telecommunication network continues to increase, payload of data traffic every year is always increasing while the voice traffic is saturated. 4G LTE (fourth-generation Long Term Evolution) as the latest technology telecommunication networks of the 3GPP (Third Partnership Generation Project) is able to provide the speed and capacity better than previous technologies. 4G LTE implementation answering the challenge of increment data needed. In the process of implementation, there are two major challenges, the limited bandwidth at 1800 MHz due to be shared with existing 2G systems DCS 1800 MHz, and demographic conditions of Indonesia that different from one area to another area. The model is built by combining the type of area with the bandwidth used ranging from 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. The model is built by combining the type of area with the bandwidth used ranging from 3 MHz, 5 MHz, 10 MHz, 15 MHz and 20 MHz. By simulating the various types of areas in Greater Jakarta and various bandwidth generated different bandwidths in each area based on the technical aspects (coverage and capacity) and the expected economic feasibility., The need for data services in telecommunication network continues to increase, payload of data traffic every year is always increasing while the voice traffic is saturated. 4G LTE (fourth-generation Long Term Evolution) as the latest technology telecommunication networks of the 3GPP (Third Partnership Generation Project) is able to provide the speed and capacity better than previous technologies. 4G LTE implementation answering the challenge of increment data needed.
