Abstract: |
In 4th generation LTE (Long Term
Evolution) and LTE-Advanced networks, there are 9 types of services, which
have different service priorities and generated traffics. Depending on the
combination of services with different priorities, about 200 radio admission
control schemes could be developed. However, international standards have no
recommendations for the construction and analysis of methods for such
schemes. Thereby, a need for admission control schemes development and
selecting the most effective ones arises. The article proposes a scheme based
on the bit rate degradation of non-real time services in proportion to the
individual thresholds chosen in accordance with the network or consumer
devices characteristics. A complex approach for analysing
the model performance measures – blocking probability, mean data transfer
time – is proposed. It is based on queuing theory via the development of a
Markov model of the admission control scheme and on verifying the obtained
results via simulation allowing arbitrary arrival process and file sizes. The results obtained in this paper could be used by mobile
operators for 4th and 5th generation network planning to evaluate the quality
of service level. |
