Kawalan kemasukan panggilan yang sesuai dalam rangkaian wayarles generasi akan datang dijangka menggunakan sumber wayarles yang terhad dan meningkatkan kualiti perkhidmatan, sambil menyokong perkhidmatan multimedia. Di satu pihak, menyekat panggilan lepas tangan biasanya lebih menjengkelkan daripada menyekat panggilan baharu. Sebaliknya, menyekat panggilan baharu mengurangkan penggunaan sumber. Lebih penting lagi, kadar ketibaan panggilan lepasan amat bergantung pada masa memegang panggilan. Skim Penyekatan Awal Rawak (CHTREB) Berasaskan Panggilan-Pemegang-Masa yang baru dicadangkan untuk mencapai matlamat yang dinyatakan di atas dalam rangkaian suara/data selular dua peringkat. Dengan CHTREB, panggilan baharu diterima mengikut beberapa kebarangkalian penerimaan dengan mengambil kira perbezaan masa penyimpanan panggilan antara panggilan suara dan data. Algoritma lelaran dibangunkan untuk mengira ukuran prestasi minat, iaitu, kebarangkalian menyekat panggilan baharu dan kebarangkalian penamatan paksa. Pertama, hasil simulasi ditunjukkan untuk mengesahkan keputusan analisis. Kemudian, keputusan berangka dibentangkan untuk menunjukkan keteguhan CHTREB. Didapati bahawa CHTREB mengatasi TR dan CHTREB-FAP di bawah kedua-dua senario trafik pegun dan tidak pegun. Akhir sekali, sistem 2 peringkat yang dikaji dibandingkan dengan rakan sejawat 1 peringkat. Ia ditunjukkan bahawa sistem 2 peringkat menunjukkan prestasi yang lebih baik dari segi purata bilangan serahan bagi setiap panggilan data.

Abstract: An appropriate call admission control in the next generation wireless networks is expected to make efficient use of scarce wireless resource and improve quality-of-service, while supporting multimedia services. On one hand, blocking handoff calls is normally more annoying than blocking new calls. On the other hand, blocking new calls reduces resource utilization. More importantly, handoff call arrival rate depends strongly on call holding time. A novel Call-Holding-Time-Based Random Early Blocking (CHTREB) scheme is proposed to achieve the aforesaid goals in a two-tier cellular voice/data network. With CHTREB, new calls are accepted according to some acceptance probability taking into account the call hloding time difference between voice and data calls. An iterative algorithm is developed to calculate performance measures of interest, i.e., new call blocking probability and forced termination probability. First, simulation results are shown to verify analytical results. Then, numerical results are presented to show the robustness of CHTREB. It is found that CHTREB outperforms TR and CHTREB-FAP under both stationary and nonstationary traffic scenarios. Last but not least, the studied 2-tier system is compared with 1-tier counterpart. It is shown that 2-tier system performs better in terms of average number of handoffs per data call.
