Abstract:
In wireless communication technologies like GSM, WCDMA, LTE, etc. Radio is stressed by the various traffic conditions, in terms of radio resources to provide the admission of new calls and required QoS. There are situations and scenarios, where the load takes unprecedented conditions and as part of services the requirements may change, like to improve on non-blocking calls though recessing on Quality of Service (QoS). Though such situations and scenarios are intermittent and last for limited periods of time, the importance of services becomes operator’s credentials. We propose a top-up algorithm, which does not interfere with existing admission control mechanism in direct way, but provide them with effective Allocation and Retention Priority (E-ARP) for each call. This algorithm is based on “inferences and intensions based combinational logic”. It works on the system specific inferences of certain parameters and intentional classification of existing and new demands based on weightage-based combinational logic, which results in modification of ARPs into effective ARPs. For evaluation of proposed Admission Control (AC) scheme blocking and outage probability of calls is used as performance metrics.
