METHOD OF PROCESSING TRANSLATION OF POTABLE GLOBAL TITLE FOR MOVABLE NUMBER

摘要

PURPOSE: A method for processing a translation of a portable global title for a movable number is provided to control a returning of a message and default global title translation(GTT), which is processed in a signaling-connection-control part (SCCP), by a number portability(NP) of GTT, by mandating the SCCP-GTT for controlling a routing of a message related a non-linear, on the NP-GTT, and to perform the portable number GTT requested additionally, caused by supplying the NP. CONSTITUTION: A method for processing translation of a portable global title for a movable number contains processes. The first process is to change a state to a corresponded signal point code(SPC) of a signaling transfer point(STP) table, if receiving information changed a state of a remote number portability-global title translation(NP-GTT) sub system. The second process is to deliver a N-STATE req primitive to a signaling-connection-control part(SCCP), for informing of a related remote sub system, if changing a local NP-GTT domestic use state, caused by a non-domestic use of a GTT database of the system, to store all information included an original subsystem number(SSN) if receiving a N-UNITDATA primitive, to perform searching and selecting a portable number table with a total digit of a given called global title, and to decide whether the searched global title(GT) is existed in the table. The third process is to decide a class of a translated SPC-type, if the global title is existed in the table, to determine a calling party address and a called party address, to compose a related parameter, and to deliver the composed parameter to the SCCP. The fourth process is to decide whether the global title is existed in a non-portable number table, after searching the table, if the global title is not existed in the portable number table. The fifth process is to perform the second process again if the global title is existed, to determine a CdPA and CgPA respectively if not, to compose a related parameter, and to deliver the composed parameter to the SCCP.
