Title: Method for Analysing Correlation Between Data Call and Voice Call
Inventor: CHA YONG TAEK
IPC: H04L12/66
Filed: 2001-12-29
Abstract: PURPOSE: A method for analyzing a correlation of a voice call with a data call increase is provided to accurately analyze a correlation between a data call and a voice call. CONSTITUTION: An interworking function is newly added to provide data service wirelessly. Thus, in order to an MSC(Mobile Switching Center) and the interworking function to smoothly perform mutual voice and data, an interface unit is required, by which the MSC and the interworking function are interfaced. A frame relay interface is recommended for a mobile data path, while an integrated service digital network interface is recommended for a PSTN(Public Switched Telephone Network). The integrated service digital network interface has been implemented and used in the MSC, and the frame relay interface is in the course of implementation. By accurately analyzing correlation between a data call and a voice call, an influence of a pilot energy rate Ec/Io accumulated during one PN chip period over a total power spectral density in a receiving band of a voice call and an error rate, and an influence of a 2-generation system when a data call is received by a repeater can be analyzed.
