Fuzzy-based decisive approach for call admission control in the LTE networks

Study on call admission control schemes in 3GPP LTE network

“…A fuzzy-based decisive approach for call admission control is presented in [30] to reduce the handoff dropping probability and ensure QoS calls in the LTE network. The scheme extracts the channel and user parameters of a call request and then passes the fuzzy module parameters.…”

“…In [34], a Fuzzy-based decisive approach for call admission control in the LTE networks was proposed to provide QoS Guarantees. The scheme employs the amount of available resources in the network to prioritize users based on the user categorization, QoS requirements, and traffic maximum delay tolerance.…”

“…The BD schemes proposed in [23,[27][28][29][30][31][32][33][34] are designed to improve the resource utilization. These schemes degrade low priority calls in order to accommodate more calls in the network.…”

“…The scheme in [33] employs variable sized degradation to address unfairness issue but has poor QoS and inefficiently utilizes resources due to failure to consider channel condition during the life time of calls. Also, the scheme in [34] employs full and partial degradation to admit high priority connections.…”
