Traditional HLR is a static database, mainly stores local user's parameter and positional information; Traditional VLR is a dynamic data base, the visiting user's of main storage parameter and positional information.Normally used HLR-BYPASS function is IMSI number (IMSI is an international mobile subscriber identity) of obtaining the called subscriber according to the data among the VLR; But the user data among the VLR may be lost because of a variety of causes, shuts down after the boots because of wireless signal reason registration failure like the user.In the core net networking frame, HLR, VLR are two relatively independent databases in the prior art, adopt traditional HLR-BYPASS method in the business continuing flow process; Its shortcoming is as if the user data loss among the VLR, and the mobile subscriber must just can communicate by letter initiatively after system registry normally; After for example mobile switching centre (MSC) equipment is restarted, under traditional prior art pattern, VLR will remove all user profile; Therefore need the user initiatively to initiate accreditation process; Exhale once such as initiatively rising, in VLR, register again, otherwise during this user of other customer calls; MSC can't obtain IMSI number of called subscriber in VLR, cause the professional failure of setting up; As behind mobile subscriber's cycle power owing to wireless reason registration failure, under traditional prior art pattern, VLR will remove this user's information; Therefore need this user initiatively to initiate accreditation process, in VLR, register again, otherwise; When other users send SMS message to this user; MSC equipment can't obtain IMSI number of called subscriber in VLR, cause short message to be kept in the cache database, can't in time issue.This not only can cause network congestion and emphasis network burden, also greatly reduces the communication call success rate, and operation is very inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of can overcome above-mentioned technical problem based on the fixing HLR-BYPASS method of IMSI generating algorithm; This method of the present invention for enterprise network or special applications net when database goes wrong; Still can keep call successful rate; Guarantee the application robustness of enterprise network and special applications net, the present invention includes following steps:
(1) HLR and VLR are integrated, i.e. BOSS database, said BOSS database is connected with BSC with MSC equipment successively;
System is according to user's MDN number when (2) opening an account, and adopts a certain fixedly IMSI generating algorithm to generate automatically corresponding IMSI number, with its static storage in the BOSS database;
The user profile of BOSS databases storage still exists after mobile switching centre (MSC) equipment is restarted; Need not the user registers again; In the speech business handshaking procedure, MSC equipment can directly obtain IMSI number of this user from the BOSS database, thereby successfully sets up professional.
Behind mobile subscriber's cycle power registration failure; This user profile of BOSS databases storage still exists; Need not the user registers again; In the short message service handshaking procedure, MSC equipment can successfully obtain IMSI number of this user from the BOSS database, in time short message issuing is arrived this user.
Advantage of the present invention be for enterprise network or special applications net when database goes wrong; Still can keep higher call successful rate; Guaranteed the application robustness of enterprise network and special applications net; Help bringing into play better the characteristic of enterprise network and special applications net, can stop because of a variety of causes causes the situation that user profile is lost in the BOSS database, the user in the system need not initiatively to initiate registration; Can alleviate the burden of network greatly, help the specialization of each function device simultaneously, greatly improve communication efficiency, have stronger practical value and realistic meaning.
