Abstract:
A method of connecting a priority call in a wireless communication system using code division multiple access (CDMA) by determining whether a total number of calls is smaller than a predetermined threshold each time a call is generated from a terminal side, assigning one of a plurality of channels in a wireless section when it is smaller than the threshold, and then connecting the related call to an exchange side, comprising:presenting a maximum threshold placed between a critical threshold constituting an upper limit of the number of calls, in terms of hardware, to which calls the channels can be assigned in said wireless section and a design threshold constituting an upper limit of the number of calls, in terms of circuit design, to which calls the channels can be assigned in said wireless section, wherein said design threshold is determined as a function of a number of channels which are required to maintain a wireless communication at a predetermined quality of service; and even if said total number of calls reaches said design threshold or more, assigning a channel to a priority call and connecting it to the exchange side when determining that the generated call is a priority call and determining that the total number of calls is smaller than said maximum threshold.
