Efficient All-IP 4G Network Architecture for Enhanced Mobility and Resource Management

This report discusses an innovative all-IP 4G network architecture designed to improve mobility and resource management in cellular networks. The authors, Young-June Choi from the University of Michigan and Kwang Bok Lee and Saewoong Bahk from Seoul National University, delve into subnet-based network solutions, physical rate-based admission control (PRBAC), and provide comprehensive numerical and simulation results. This research aims to optimize quality of service (QoS) in mobile environments, demonstrating effective admission control schemes and mobility models for seamless connectivity.

  2. Outline • 一、 Introduction • 二、All-ip cellular network 1.All-ip 4G network 2.Subnet-based 4G network • 三、Network architecture for efficient multiple access 1.

  3. 一、 Introduction(1/5) • Title • 大 • 小

  4. 二、Physical Rate Based Admission Control(1/5) • AP distributes TXOPs to individual QSTAs according to their instantaneous physical rates.

  5. 三、NUMERICAL RESULTS(1/3) • Each QSTA has one QoS connection.

  6. 四、 SIMULATION RESULTS(1/3) • Topology • The QoS session requests from QSTAs to the QAP arrive according to Poisson distribution with the average arrival interval changing from 5 s to 12 s, and the lifetime of a QoS session is assumed to be exponentially distributed with a mean value of 50 s. • One QSTA has at most one QoS session at a time. • QSTAs in the QBSS move according to the so-called “random waypoint” mobility model [9].

  7. 五、 CONCULSIONS(1/1) • They have proposed the novel PRBAC admission control scheme.
