Abstract

A method for computing maximum traffic capacitance of a base station using a virtual call in the digital mobile communication system in such a way that an operator at operating terminal for Base Station Manager (BSM) inputs call-set-request instructions using the virtual call to maintain and repair the digital mobile communication system so that traffic state is set between mobile stations in the service area of test base station and a vocoder of a Base Station Controller (BSC) to compute maximum traffic capacitance of the test base station. An operator at operation terminal inputs call set information by operator instruction as much as mobile station numbers to be tested to compute maximum traffic capacitance of the base station. The BSM inputs a virtual call-set-request-instruction by means of a virtual call-set-start-flag. A virtual call-set-path is given among the vocoder of the BSC, the channel element, and the mobile station without going through Mobile Switching Center (MSC) that processes call setting and switching of a traffic path.

Claims

1. A method for computing maximum traffic capacitance of a base station using a virtual call in a digital mobile communication system comprising the steps of:

inputting and storing information for test mobile stations to a call set managing data base of a Base Station Manager (BSM) to compute maximum traffic capacitance of the base station;

requesting call set-up to a Call Control Processor (CCP) using instructions according to call type to set up virtual calls to the test mobile stations;

receiving information regarding the call setting and call cutting from the CCP, renewing the data base for the test mobile stations and outputting mobile station numbers on service; and

outputting statistics for mean maximum traffic capacitance of the test mobile stations.

2. A method for computing maximum traffic capacitance of a base station using a virtual call as claimed in claim 1, in which the step of setting virtual calls further comprises the steps of:

initializing the call set managing data base and a maximum traffic capacitance computing data base for each mobile station upon request for a virtual call-set-start-instruction from an operator;

identifying whether a call-set-flag is set as start; and

when the call-set-flag was set as start, sending, by the BSM, a packet having the call-set-information for the test mobile stations in the call set managing data base of the BSM and virtual call type information to request call set to Call Control Processor (CCP), sending, by the CCP, a call-set-request-message to Base Transceiver Station Control Processor (BCP), and sending, by the BCP, information on whether the call set has been completed to the CCP after performing action for setting call.

3. A method for computing maximum traffic capacitance of a base station using a virtual all as claimed in claim 1, in which setting of the virtual call comprises that when BSM requests the virtual call, BTS calls MS through a paging channel, the MS reports response for the virtual call to the BTS, the BTS sends forward null traffic data to the MS after activating of a traffic channel, the BTS informs the MS of allocation of the traffic channel, the MS sends reverse null traffic data to the BTS to maintain connection with the BTS, the BTS informs BSC of acquisition for the reverse null traffic data, the BTS informs the MS that the traffic channel is available, the MS acknowledges to the BSC for the informing of the BTS, and the BSC reports setting of the virtual call to the BSM.

4. A method for computing maximum traffic capacitance of a base station using a virtual call as claimed in claim 1, in which the step of renewing the data base comprises the steps of:

checking on whether the call setting has completed;

renewing, when the call setting has completed, a call-set-start-flag to “

set up”

in the call set managing data base;

renewing, when the call setting has not been completed, the call-set-start-flag to “

no set up”

in the call set managing data base;

renewing maximum traffic call numbers, minimum traffic call numbers, call setting request numbers and call numbers on service in the maximum traffic capacitance computing data base and outputting the associated information to the operator; and

identifying that service states of the test mobile stations have reached a predetermined limit value.

5. A method for computing maximum traffic capacitance of a base station using a virtual call as claimed in claim 1, in which the step of outputting statistics comprises the steps of:

if it is judged that the service state has reached the limit value in the step of identifying that service states of the test mobile stations have reached a predetermined limit value, inputting mean maximum traffic capacitance request using scanning times representing that an operator is intended to take statistics through setting of the virtual call how often, the scanning times also representing the time for calculating mean maximum traffic capacitance in relation with the mobile stations on service;

designating the mobile stations on service to maximum traffic number, minimum traffic number or the whole number of the mobile stations on service during the time requested from the operator and starting initializing operation for computing traffic based on the designation;

identifying that the scanning times have ended; and

when the scanning times have ended, outputting information for maximum service call numbers, minimum service call numbers, call-set-request times and mean service numbers.

7. A method for computing maximum traffic capacitance of a base station using a virtual as claimed in claim 1, in which the type of the virtual call is Markov call or Service option 2.

6. A method for computing maximum traffic capacitance of a base station using a virtual call as clam 1, in which a virtual call is set among vocoder of Base Station Controller (BSC), channel element and the test mobile station.
