Abstract—Call admission control (CAC) is a key enabling technique to ensure quality of service (QoS) provisioning for mobile users. Limited fractional guard channel is one of most effective strategy in call admission control. Inter-cell interference coordination (ICIC) is considered as the most promising approach for LTE to mitigate inter-cell interference. One important approach for ICIC is soft frequency reuse (SFR). In this paper, a new analytical model is derived to evaluate LFGC strategy in SFR-based systems. The performance measures of interest are new call blocking probability, handover dropping probabilities, throughput and mean time response. Further, discrimination in the analysis between cell-core and cell-edge is performed. All performance metrics is deduced separately at each cell zone.

Index Terms—Queuing, limited fractional guard channel, soft frequency reuse.
