Abstract:
A method of testing a (link power control in a mobile communication system, the method comprising the steps of:(a) a BSM requesting a BTIA to control the forward power, and the BTIA, which received the forward power control request, sending ""mobile on"" signal to a mobile;(b) the BTIA receiving information about a reception power and error rate from the mobile and outputting a signal responding to the power control request to the BSM, and the BSM sending ""markov on"" signal to a TSB (Transcoding Select Bank);(c) the TSB outputting a call setting signal to the mobile, the BTIA receiving the call setting signal from the mobile, and outputting a signal for confirming if the call is set to a BC(d) the BCPA outputting a signal requesting call information to a channel card, the channel card sending a signal responding the call information to the BCand the BCPA outputting a signal responding to call setting information to the BTIA;(e) the BTIA sending the current state of the BSM to report the current state of the forward link, the BSM comparing the received error rate with a critical value and outputting a transmission power control command to the BTIA based on the compared result, and the BTIA which received the transmission power control command instructing the mobile to control its transmission power;(f) the BTIA , which received the information about the reception power and error rate from the mobile, outputting a signal requesting the forward power control to the channel card, and the channel card raising the transmission power and reporting the transmission power rising state to the BTIA at a predetermined period;(g) the BTIA, which received the transmission power rising state from the channel card, sending information about the progress of the forward power control to the BSM, the mobile including a message continuously requesting correction at a predetermined period into a traffic channel until it can normally receive signals, and transmitting the message, and the BTIA and channel card repeating the step (f); andthe channel card informing the BTIA that the power control is finished when the receiving state of the mobile is stabilized, and the BTIA outputting a signal informing the completion of the forward power control to the BSM.
