Analysis of performance measures for scheme model with limit power policy within LSA framework

Current IT development is closely associated with the question of rapid increasing of transmitted data volume in the context of mobile networks frequency band limitation. Shortage of system resources, which are required for provision services with a high Quality of Service (QoS) and Quality of Experience (QoE) to users, leads to data rate reduction in mobile networks, and consequently reduction of QoS and QoE. One of the question possible decisions is use of Licensed Shared Access (LSA) technology, developed with the support of European Commission (EC). The LSA system is an example of the effective use of the frequencies spectrum taken by the mobile operator for leasing from the owner, who uses this range inconsistently. At any given time, either the owner or the tenant operator uses the LSA frequency spectrum. The owner has absolute priority in the use of his frequencies, realized through various scenarios, for example, the interruption of mobile operator users serving. An important parameter in such systems performance indicators determining is the user remoteness from the base station (BS). The model scheme of radio frequencies sharing in the LTE (Long-Term Evolution) network with the LSA system is proposed. There was implemented a scenario of limiting the BS signal power, which transmits data to devices that occur randomly and uniformly distributed on the plane. Aerial telemetry is considered as an example of the LSA scenario. The main model service quality indicators are the blocking probability, the average data transfer rate, the average number of users in the system. To calculate these parameters, a recursive algorithm is proposed in the article. © Copyright 2017 for the individual papers by the papers' authors.
