PURPOSE: A time slot hunting method is provided to minimize a call failure and a call disconnection by properly distributing a call corresponding to one time slot and preventing a call corresponding to a link, a pipe or a trunk from discontinuing at one time in a link, a pipe and a trunk field. CONSTITUTION: A loop variable is initialized as '0'(S1). If the loop variable is below '31'(S2), a link to hunt a time slot is computed to obtain with the previously hunt link value and a pipe value(S3). It is determined whether a physical link has been set for the obtained link(S4). If a physical link has not been set, the loop variable value is increased(S5). It is determined whether a hunt-available pipe is a pipe '0' or a pipe '1'(S6). If the hunt-available pipe number is '0', it is determined whether time slot count is below 20(S7-1). If the time slot count is above 20, the hunt-available pipe number is changed(S8). If the time slot count is below 20, a time slot is hunt at the pipe '0'(S9-1). It is determined whether the hunting has been successful according to whether the previously hunt time slot value is a negative number or a positive number(S10-1). If the time slot hunting has been successful, the time slot count and a link count are increased and the time slot value returns(S11-1). If the hunt-available pipe number is '1'(S6), it is determined whether the time slot count is below 20(S7-2). If the time slot count is above 20, the hunt-available pipe number is changed(S8). And then, a time slot is hunt at the pipe '0'(S9-2). It is determined whether the hunting has been successful according to whether the previously hunt time slot value is a negative number or a positive number(S10-2). If the time slot hunting has been successful, the time slot count and the link count are increased and the time slot value returns(S11-2). |
