Embodiment
Provide the preferable embodiment of the present invention below in conjunction with Figure of description.
The method of telephone exchange cutover without number change of the present invention can be divided into following components and carry out:
1, at first carries out the relaying cutover.With the whole cutovers of interoffice junction between other owning administration in the net and the former office on newly found the bureau, former office with newly innings between offer direct junction.That is: newly found the bureau and become the tandem exchange of old office, by the coming of all old offices of tandem of new office, outgoings.
This cutover work can once be finished or time phasing.Can directly use the signalling point of old office in the stylish office of a cutover.Carry out as distribution, new office needs to distribute new signalling point, and performs signaling link cutover again with local Signalling Transfer Point (LSTPLow-level SignaLIng Transfer Point).Wherein LSTP plays Signaling System Number 7 switching effect in network, is general definite technology.
2, subscriber installation:
Former office subscriber installation is arrived new office, the step of this cutover, substep cuts to new office from old office one by one, this process can be to continue smoothly to carry out, promptly only needing to revise location data gets final product, do not need to revise Subscriber Number, the quantity of a cutover is not required yet, therefore saying so continues smoothly to carry out.This also is the present invention and traditional bigger difference of method for cutting over.
In the process of whole subscriber installation, do following processing for incoming call not in the know:
For incoming call outside the owning administration, all arrive first new office and land (this moment, the relaying cutover was finished), search just directly connection of the number (cutover) that has in the new office of discovery by user data table; Rerouting to former office for the not cutover user who is distributed in former office point lands.So to the spacing situation, then new office directly handles as failed calls.Former office all lands for the calling of going into relaying, confirms because search user data table through new office.This process of landing mainly is to search user data, and wherein user data table comprises the data of customer location.
The present invention also by switch by built-in services device veneer (ISP) and flexibly the FH-number transform function reach above-mentioned requirements, thereby for old network renovation provides good means, can satisfy the constant requirement of number in the transformation process.The ISP veneer adopts the digital SPC exchange circuit board to realize among the present invention, can flexible configuration, reach five pairs at most, and realize different software functions by loading different business softwares.Among the present invention the built-in veneer of its switch is realized that 1,000,000 above user data protect.
In the present invention, the ISP plate adopts the above rank chip design of PII, realizes high-capacity and high-speed data query business.When adopting the 64M internal memory, the memory cost of a record is 50BYTE, and every block of plate is supported ten thousand data of 64M/50=100, and internal memory extends to 256M.Every block of plate is supported 900 times/second inquiry velocity, supports the inquiry velocity more than 6400K/ hour during a pair of plate load sharing, guarantees that above-mentioned data can access real-time processing.
In the process of whole subscriber installation, following processing is done in exhalation for intra-office:
The exhalation of all intra-office subscribers all continues by new office, and the user of former office gives orders or instructions to make the office data change, all send new office.Do the prefix analysis by new office, and continue.As called be the local exchange prefix, then further search, or land (cutover user) or transmits and return former innings (not cutover user) in new office by user data table.
By former office call source code is set, call source code is the new office of sending of user, and call source code is landing of relaying.
Below in conjunction with example, the process of concrete telephone office's cutover.
As shown in Figure 1, be the schematic diagram before end office's switching equipment is transformed, we establish it is 25 innings, signalling point is AAAAAA.
An existing newly-built exchange as shown in Figure 2, is established it and is new office, and signalling point is BBBBBB, networks at signaling network.
Adopt method of the present invention, can comprise that following step finishes the cutover of telephone office:
The first step, according to the engineering survey result, substep is finished the cutover of each office direction relaying, as shown in Figure 3, look the complexity of relaying distribution, but the relaying of each one or several office direction of cutover, the relaying of simultaneously former office newly-built and new interoffice with this part relaying that is available, before between the relaying cutover is intact, the user does not carry out earlier cutover.
Second step was a subscriber installation, the user in batches cutover on newly found the bureau, each handshaking procedure as shown in Figure 4 at this moment, former office send new office to handle all-calls (comprising Home Exchange Call), the number analysis table is searched by new office, if the user not in new office, configuration data then, it is carried out FH-number transform, be routed to former office and handle.As 2510808 callings 2510909, then striking out send new office to handle, if the user is not in new office, then utilize ISP FH-number transform function, add a prefix in the number front, as add " 99 ", become 992510909,99 are routed to former office during number analysis, deduct 99 when striking out.Because the FH-number transform function of ISP is very powerful, can finish large-scale FH-number transform, thus can carry out FH-number transform at number section of relatively disperseing or at Subscriber Number, and be routed to former office.And this scheme can not produce a large amount of infecctive call, if all not the number in new office all send former office to handle, then have a large amount of real spacings and continue to send former office to handle, and the number that utilizes ISP really to exist carries out conversion, can avoid a large amount of infecctive call to produce.
In the 3rd step, cutover finishes, and as shown in Figure 5, net moves back in former office, and the relaying between former office and the new office can be used for the relaying dilatation.
According to the above, the present invention can accomplish the substep cutover at the transformation cut-over process of digital SPC exchange, and does not revise Subscriber Number; Adopt the big capacity internal database of digital SPC exchange of similar built-in services device veneer (ISP) form in cut-over process, being used for locating the number position is in former office or in new office; Infecctive call such as spacing is no longer delivered to former office and is handled in cut-over process, guarantees not to be subjected to the impact of ineffective traffic former innings; In the process of substep exchange cutover without number change sign indicating number, do not need other office points of PSTN (public switched telephone network) to cooperate data such as making FH-number transform, reduced impact to PSTN (public switched telephone network).
The above only be preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto; any people who is familiar with this technology; in the technical scope that the present invention discloses, the variation that can expect easily or replacement all should be encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
