The telecom network which selects cost smallest path

摘要

(57) Abstract As for this invention, the telecom network which can do path allocation on the basis of the exchange operational data (1,19,29) it regards. As for exchange operation, it is done the place where the optimum path which is decided on the basis of defined possible function is described, on the basis of the exchange operational data which is stored. Furthermore specifying, if you say, to decide fee (the LCR data) of on the basis it is possible the exchange operational data. For example at least making use of LCR function, portion of the user in order to make the rise of fee smallest for the user of telecom network of the place where the location is left to the distance, the private private branch exchange which multiple has joined mutually (2-1,2-2 andThe respective storage means in order, 2-n, 21,24,30,31,32) is provided, in the said private private branch exchange to store the exchange operational data (6-1,6-2 and6-n) is allocated, in addition as for the said private private branch exchange, telecom network the subscriber terminal where (1) is located inside or outside (22,37,52) to treatment means in order to decide optimum path (7-1,7-2 and7-n) it includes, the path which to one (21,30) from outside among the private private branch exchanges keeps going with that, is led, or passes and is led, one or other private private branch exchanges of a quantity above that (24,31,32) passing, and, one or other telecom networks of a quantity above that (26,38,51,52) or in each case one side or it is both.
