  • This paper attempts to maximize the operator's revenue while simultaneously providing a multi-constraint, multi-hop and deterministic QoS provisioning for real time traffic in IEEE 802.16m based 4G networks. The optimal solution to such a problem is NP-complete and therefore not feasible to be solved in a tolerable polynomial time. For this reason, we also provide a simple price based greedy heuristic to be used along with the admission control. Simulation results for different QoS schemes show that the heuristic produces a revenue that is very close to the optimal revenue, and is far more aggressive than the size based and other common algorithms that are computationally feasible to be implemented in IEEE 802.16m.

  • 본 연구는 이동통신 정책변화에 따른 사업자간 경쟁양상을 분석하였다. 이동통신 시장은 시장진입이 제한적으로 한정된 사업자들이 독점 형태로 경쟁하게 된다. 이 과정에서 정부는 소비자의 권리보호 및 기업들 간의 유효경쟁체제를 위해 기업의 경제활동을 규제하는 역할을 해왔다. 그동안 이동통신시장에서의 정부규제에 대한 성과나 결과를 분석하는 많은 연구들이 있었지만 제도의 중첩으로 인한 복합적 양상을 분석하는 연구는 부족하였다. 이에 본 연구는 실제 데이터를 사용하여 제도의 중첩으로 인한 사업자 경쟁구도의 복합적 양상을 확인한 첫 연구라는 점에서 그 의의를 갖는다. 본 연구는 기업의 성과지표인 가입자 수, 번호이동자수, 매출액 등의 실증데이터를 사용하여 정책변화에 따른 통신사업자간 경쟁양상을 연구하였다. 연구결과 통신시장에 도입된 정부 정책은 시장경쟁 촉진과 고착화된 경쟁구도 완화에는 긍정적인 영향을 미쳤지만 통신사 재무성과 개선 측면에선 부정적인 영향이 있었음을 확인하였다. 특히 단통법은 이동통신사간 유입영향력 차이를 줄이며 시장 안정화를 유도하고 MVNO의 점유율 상승에 발판을 마련하는 등의 긍정적인 효과도 있지만, 일정 기간 이후 기존 MNO 사업자의 영향력이 증가하여 MVNO의 경쟁력이 약화되는 부정적 변화를 확인하였다.

  • Many telecommunication operators around the world have multiple networks. The networks run by each operator are always of different generations, such as 2G and 3G or even 4G systems. Each system has unique characters and specified requirements for optimal operation. It brings about resource allocation problem among these networks for the operator, because the budget of each operator is limited. However, the evaluation of resource allocation among various networks under each operator is missing for long, not to mention resource allocation optimization. The operators are dying for an algorithm to end their blind resource allocation, and the Resource Allocation Optimization Algorithm for Multi-network Operator (RAOAMO) proposed in this paper is what the operators want. RAOAMO evaluates and optimizes resource allocation in the view of overall cost for each operator. It outputs a resource distribution target and corresponding optimization suggestion. Evaluation results show that RAOAMO helps operator save overall cost in various cases.

  • Recently, mobile wireless data traffic has been dramatically increased due to not only the popularization of digital convergence devices including smart phone, Net-book, and Tablet PC, but also the vitalization of wireless Internet related eco-systems such as AppStore. In addition, it is expected that a tremendous increase in mobile data is caused by the release of unlimited mobile data plans (flat-fee). In order to deal with such mobile data traffic explosion, it is necessary that network operators should make efforts to offload wireless data traffic. This paper reviews the condition of mobile wireless data traffic in domestic and international telecommunication industry and looks for various action plans to overcome the difficulty of network operators.

  • As the gaps become narrower in interconnection fee and volume rate, the MNOs began to introduce flat pricing for unlimited voice traffic competitively in Korea wireless telecommunication market : 'unlimited talks within intra-network' by the 1st operator, followed by the 3rd operator's 'unlimited talks over all networks'. As a result, subscribers tip in toward the third ranked operator and could bring a substantial change to steadfast market structure over the last decade in Korea. This paper aims to develop a simple economic model to analyze competition with flat pricing for unlimited voice traffic, and to check whether the pricing can be appropriate for the MNOs. The results show that MNOs already step in the necessary conditions to launch flat pricing for voice traffic. It also predicts that the MNOs compete with unlimited talk over all networks and set a single fee in an equilibrium. At present, the MNOs run virtually identical pricing for unlimited talk over all networks, considering their differentiation with respect to service quality, coverage and brand preference.
