“…In [10] the authors consider two service categories with different priorities, with additional handoff sessions being considered of high priority as well, thus forming three zones. Considering network load variability, zone limits can be variable as well, e.g., in [11] and [12] there are two different service categories, and the zone limits are dynamically adjusted based on the proportion of higher category sessions. The approach proposed in [13] allows for different possible bandwidth configurations to be assigned to sessions by considering maximum and optional bandwidth values for new sessions.…”

The increasing use of complex multimedia services requires advanced resource management mechanisms, in particular in wireless network environments. Since multimedia services may contain several media flows, the number and properties of which may vary during an ongoing session, and because user preferences regarding flow importance may also vary, we use "user" and "service" related knowledge at session initiation to specify alternative service configurations that can be enforced in cases of decreased resource availability. We apply this knowledge in the context of admission control, by proposing an algorithm allowing for sessions to be admitted with lower quality configurations in cases when there are not enough resources to admit optimal (highest quality) configurations. We hence show that such an approach leads to an increase in session admission probability. We evaluate the proposed model using a developed simulator tool named ADAPTISE that simulates arrivals, durations and resource allocation of multimedia services. Furthermore, we have rerun the ADAPTISE simulation traces in an LTE network simulator tool to test session performance metrics.

“…Good CAC strategies must balance new call blocking with handoff call dropping to satisfy quality of service (QoS) requirements. The earlier CAC algorithms [19][20][21][22] considered the effective traffic load of the target cell to determine whether the call should be accepted. However, these methods ignore the interference of to-be-accepted calls by the neighboring cells.…”

Fuzzy call admission control combined with distributed dynamic channel assignment and reassignment for cellular mobile systems

In a cellular mobile system (CMS), the service area is divided into cells, each of which has numerous channels, which are shared by two types of call -new calls and handoff calls. Giving a higher priority to handoff calls than new calls is common practice. However, giving too much priority to handoff calls will result to excessive blocking of new calls. This work firstly proposes a distributed dynamic channel assignment and reassignment (DDCAR) scheme to satisfy three types of constraint -co-channel constraint (CCC), adjacent channel constraint (ACC), and co-site constraint (CSC), simultaneously. The purpose is to minimize the number of available channels that become unavailable for the assignment to new calls and to maximize the number of unavailable channels that become available for release when calls complete. To provide a higher priority to handoff calls, a fuzzy call admission control (FCAC) scheme, combined with the DDCAR, is proposed herein for implementation at the base station. A 7 × 7 CMS with two traffic patterns is employed as the test example. The test results reveal that the FCAC scheme significantly reduces the dropping probability of handoff calls at the cost of increasing the blocking probability of new calls to an acceptable level.
