A method for calculating a capacity change and an effective channel ratio per sector according to a soft handoff ratio of a code division multiple access network

摘要

A description will be made of a method for calculating the actual required amount of network configuration equipment by defining a proper soft handoff and selecting a ratio in designing a wireless network of a digital mobile communication system and a personal portable communication system using a code division multiplexing method. The effective channel ratio calculation method is a method for calculating the effective channel ratio in a wireless mobile communication system designing a digital mobile communication system using a code division multiplexing method, $H$_AT Is the total handoff area ratio $R$_EFFECTIVE = . If the coverage radius of the sector is serviceable with the best signal quality is D, $H$_AT 1 and 0? DELTA R? D, if the radial difference DELTA R according to the soft handoff area ratio is D ). And the 2-way handoff area ratio $H$_A2 The $H$_AT - 2· , The 3-way handoff area ratio $H$_A3 2 · . $H$_CT Is the total handoff channel ratio, the related equation between soft handoff channel ratio and area ratio is $H$_CT = . This method clarifies the relationship between the area ratio of the soft handoff and the channel ratio and clearly defines the difference to prevent the use of the term and mixed use and to calculate the ratio of 2-way and 3-way handoff among the total handoff ratios And informs the degree of change of the capacity of the entire mobile telephone network accordingly. In this method, the soft handoff area ratio and the channel ratio are related, the soft handoff area ratio and the channel ratio are significantly different from each other, and the number of effective channels and the channel ratio are newly defined, It can be easily applied to the selection of the minimum required number of base stations in the wireless network design or to select the maximum number of the reception subscribers according to the predetermined number of base stations.
