Problems solved by technology

[0005] (1) It is necessary to introduce new network elements into the network, not only to transform the existing network, but also to add many protocol interfaces, which is more complicated to implement
[0006] (2) Since the fixed network does not support access to NPDB, the above solution is currently only applicable to number portability services between different mobile networks

Abstract

By introducing two parameters which are 'user home network' and 'network access code', and adding a conditional judgment before returning enquiry result by HLR, the invention implements returning the service data enquiry request from user requiring to change network to its current home network to make process so as to ensure that the service request and service process are executed according to the mode of its home network, and further to implement the two value-added services which are the changing network and not changing mobile number and the MNP (mobile number portability).

Description

technical field [0001] The present invention relates to a system and method for realizing cross-network use of user telephone numbers, more precisely, to a system and method for realizing cross-network use of user telephone numbers based on user home register HLR, and belongs to the technical field of telephone communication network. Background technique [0002] In order to realize the portability of numbers in the telephone network and the mixed allocation of telephone numbers, two numbers need to be assigned to users: logical number and physical number. The number is also the number announced by the user to the outside world and the number used by the operator to identify the user and charge, as the user's identification; the physical number is also called the routing number LRN (Location Routing Number)-it is the access number assigned by the user's home network to the user terminal , which is also the routing number for the switching device to find the real location of ...
