Abstract: PURPOSE: A method for transmitting a call in a paging system is provided to prevent a call process from being delayed when an error in a telocator network paging protocol(TNPP) port is generated. CONSTITUTION: Each processor checks the state of the TNPP port(S31). It is determined whether an error occurs in the TNPP port(S32). If the error occurs in the TNPP port, the processor reads in a call from a queue buffer in order to store it in a memory(S35), and then inserts the stored call into the queue buffer of a different channel by a load sharing technique(S36). The processor transmits the call inserted into the queue buffer to a paging terminal(S37). If the error does not occur in the TNPP port, the processor reads the call from a corresponding queue buffer, and then encodes the read call by a TNPP format(S33). The processor transmits the encoded call to the paging terminal via the TNPP port(S34).
