“…Besides the considered factors, which have influence on the mean value of output power of each channel, two more factors have influence on the mean BTS output power: part of intra-cell connections, [4] and [9], and the use of one channel for two connections (half rate), [10] - [12]. Intra-cell (or internal) connections in the cell always exist, but in different percent.…”

Original scientific paperThis paper compares the influence of various factors on the output power of each GSM channel and connection, and on the output power of whole base transceiver station in GSM network. The considered factors are the influence of sending signal only when speech exists (DTX), implementation of power control in signal sending, influence of users' distribution in the range of coverage of base station, the power of one intra-cell connection and the power of one half-rate connection. It is analyzed how emission power of base station can be reduced by implementing various methods in signal sending.

“…In order to reduce losses caused by the lack of channels on Air-interface, dynamic channel allocation with half rate (HR) is often used, [1], [10], [11], [12]. Usage of HR connections by the implementation of repacking channel assignment is considered in this paper.…”

“…Table 2 indicates that with larger array sizes, not only does the percentage of blocks received with the optimal CS increase but also the usage of CS4. 3 It is important to remind that CS4 is the coding scheme that transmits the higher payload in an RLC block and that its use is considered when operating under good radio conditions. As a result, a higher use of CS4 is actually an indication that the channel quality conditions have improved.…”

For example, [3] proposes different channel allocation mechanisms designed to improve blocking probability whenever half-rate and full-rate connections are considered in a GSM system.

Abstract. This paper proposes and evaluates a set of physical level assisted cross-layer channel assignment schemes. These schemes allocate an incoming call the available channel that experienced the best channel quality conditions during previous transmissions. To estimate such conditions, three different link quality metrics have been considered. The performance of the proposed schemes has been compared to that of the commonly employed random allocation mechanism. The obtained results show that the proposed schemes improve the system performance of an adaptive packet-switched mobile radio system while also exhibiting the long-term channel uniform use characteristic of the random allocation mechanism. The higher performance attained with the proposed schemes is due to their short-term channel use pattern that results in an implicit cooperation among co-channel interfering cells during the channel allocation process. With the proposed schemes, interfering cells avoid assigning the same channels to simultaneous incoming calls, therefore reducing the experienced interference and increasing the system performance.

Abstract-Channel allocation techniques are responsible for deciding which available channel is assigned to new transmissions. Since channel quality conditions and dynamics experienced during data transmissions can be affected by the mechanism used to assign free channels, this paper proposes and evaluates different channel allocation techniques in an adaptive packet-switched mobile radio network. The common criteria used for all the techniques under consideration is to assign incoming calls the available channel that experienced the best channel quality in previous transmissions. The difference between the proposed algorithms is the metric used to evaluate the channel quality. In particular three metrics are considered: BER, BLER and mean CIR. The results obtained highlight considerable performance improvements compared to other traditional techniques, such as random channel allocation.
