The solution of the present invention can satisfy above-mentioned requirements.

(3) NP system of the present invention (being called the LS-NP system) architecture

LS-NP of the present invention system is beneficial to the standardization of communication network with reference to the architecture of Intelligent Network.System adopts Service Switching Point (SSP, Service Switching Platform) to add service control point (SCP, Service Control Platform) scheme.

LS-NP of the present invention system comprises switching plane and business platform, and switching plane is the service switching point is similar to intelligent network on function operation exchange/CCF SSF/CCF, and has comprised the signaling access function SAF in the intelligent network; And business platform to be the service control point (SCP) comprise service management control SMCP (Service Management﹠amp; Control Point) and Service Access point SMAP (Service Management Acess Point), Service Access point SMAP Service Access point SMAP in the corresponding intelligent network on function wherein, service management control SMCP the service management function SMF in the then corresponding intelligent network, service control function SCF and service control function SCF and business datum library facility SDF on function; Interface protocol between the SMCP of service switching point and service management control simultaneously then meets the C-INAP agreement of intelligent network.So Service Switching Point adds service control point SSP﹠amp; SCP has possessed the feature of intelligent network on structure and interface, when can satisfying the NP business, also possessed the ability that seamlessly transits to intelligent network.The architecture of its system as shown in the figure.

The characteristics of service switching point in this LS-NP system: the service switching point is as the operation exchange platform in the LS-NP system, based on the LS-PS programmable switch, mainly finish CCF CCF, Service Switching Function SSF and Call Control Access Function CCAF, the application protocol between service switching point and the business platform is followed China-Intelligent Network Application Protocol C-INAP agreement.The service switching point has stronger network-adaptive ability and system processing power.The service switching point can provide the signalling system No.7 of China's No. 1 signaling and 14/24 compatibilities, phone application part (TUP) and integrated services digital network ISDN applying portion (ISUP) can with the switching equipment cooperating of various standards.The service switching point flexible configuration adopts module to select the add mode smooth expansion, at each module private resources such as flexible configuration relay resource, master control resource, subscriber line circuit resource and voice as required.The classification decentralized control structure is adopted in the service switching point, and intermodule adopts full decentralized control structure, and its single module capacity can extend to 56 by No. 30 relayings (30DT) ^*30DT, the voice time slot can expand to 512 the tunnel by 32 the tunnel.Carry newspaper newspaper system for electrical teaching and Voice Mailbox.The service switching point of native system (being called LS-SSP) has to get on well with others inserts the statistical function that hives off, complete Chinese man-machine interface is provided, can finish functions such as traffic measurement, real time monitoring, data management, attended operation, failure diagnosis and warning system can be traced and monitored the system failure, and and advance to solve fault.

The characteristics of service control point (SCP) in this LS-NP system: the service control point (SCP) plays a part management, control and handles the NP business in whole NP platform, also can handle other IN service, it finishes service management function (SMF), each service data function of Service Control Function (SDF), and the service control point (SCP) mainly comprises above three partial function softwares.Service management function (SMF) is mainly used in management service build environment SCE and the professional loading of SMAP SMAP etc., service management function SCF mainly is responsible for the access of the calling of service logic, service switching point etc., the main management data of service data function SDF is as NP number (original number that is kept after the telephone-moving) corresponding physical number, metering data, service condition etc.

Service control point (SCP) and service switching point in service switching point+service control point (SCP) structure are generally built same machine room in, connect to guarantee that communications protocol is TCP/IP by the communication bandwidth by local area network (LAN), and application protocol is C-INAP; Insert in the signalling system No.7 mode with being connected of external business exchange point SSP by interior business exchange point SSP.

Service creation environment SCE offers the ability that the Telecom Carrier generates needed business, it provides patterned man-machine interface and meets the individual member SIB of ITU-T, edit service logic flow process and service related data as user's effect, connection, Apply Charging etc. to the operator, as speech data, card number length etc., and provide the business simulating function, the business that can Simulation execution generates is to guarantee professional online reliability of operation.Service creation environment SCE is loaded into the service logic that generates on the service control point (SCP) in modes such as data files, is responsible for professional management by the service management function SMF on the service control point (SCP), comprises professionally setting up, provide, move, cancel and closing.Suggestion service control point (SCP) and service creation environment SCE build same machine room in, connect by local area network (LAN), also can be not together to connect (if only go up the NP business, can dispose SCE, just the NP business software that use LS-NP provides can) by wide area network.SMAP SMAP provides interface with service-user to finish the management of Service Management Control Point SMCP to the NP service-user, user's functions such as registration, data modification inquiry and user's deletion are finished in its logical professional or other professional application of NP that is placed on the direct accepted user in business hall.Owing to geographical the dispersion, a plurality of SMAP SMAP can be arranged in platform.

The LS-NP network connects:

1) service switching point is to the service control point (SCP): at LS-SSP﹠amp; In the architecture of SCP, ethernet interconnect is passed through in service switching point and service control point (SCP), adopt ICP/IP protocol, its physical interface adopts the embedded with network interface (10M/100M is optional) of LS-PS programmable switch, on the one hand, the INAP message of service switching point comprised convert TCP/IP message bag to, be transmitted to the service control point (SCP); On the other hand, the TCP/IP message bag that the service control point (SCP) is sent converts INAP message bag to, is transmitted to the service switching point.

2) service control point (SCP) is to SMAP SMAP: this LS-NP system adopts client/server (Client/Server) pattern to support the login of a plurality of management access point SMAP to the service control point (SCP).SMAP SMAP is the interface that a user of service control point (SCP) inserts, can bear the task of all service control point (SCP) operation inputs, can be by the master data base on the Client/Server mode access service control point (SCP), the use of limited subscriber at incoming end come by the control of authority of strictness in the service control point (SCP).

As shown in Figure 2, SMAP SMAP has following several access way to the service control point (SCP): 1, SMAP SMAP and service control point (SCP) are when nearer, SMAP SMAP passes through Ethernet, adopt ICP/IP protocol to be linked into the service control point (SCP), connect for local area network (LAN) this moment; 2, when SMAP SMAP and service control point (SCP) apart from each other, SMAP SMAP utilizes Leased line DDN special line to be linked into the service control point (SCP) with asynchronous system by router and relay contact DTU; 3, when SMAP SMAP and service control point (SCP) apart from each other, SMAP SMAP utilizes telephone wire to insert the service control point (SCP) by modulator-demodulator Modem, is public switched telephone network PSTN connection this moment.

The expansion of service switching point+service control point (SCP) architecture: the architecture of service switching point+service control point (SCP) is that service switching point, service control point (SCP) and the SMP etc. in the intelligent network networking combine, and the networking structure of a kind of simple, the actual effect that produces, the proposition of service switching point+service control point (SCP) architecture, be to consider some telecommunication bureau, press for IN services such as introducing NP on the one hand, to increase economic efficiency; On the other hand because some reason, can not settle at one go or temporarily do not need to set up intelligent network at present.Adopt Service Access point SSP to add the networking plan of service control point (SCP), both can in local network, realize IN service (comprising the NP business), because it can provide standard, open interface, therefore also can satisfy the needs of network upgrade in the future again.Its expansion can be divided into dual mode:

1) the exchange point SSP that branches out: after a plurality of service switching points are arranged in the network, can consider to the transition of intelligent network system.By the mutual INAP operation of standard Signaling System Number 7, service switching point+service control point (SCP) of this moment is equivalent to the Service Management Control Point SMCP in the intelligent network, finishes service control function between service switching point and the service control point (SCP).Network configuration as shown in Figure 3.

2) the control point SCP that branches out: sharply increase when NP is professional, the disposal ability that has exceeded the service control point (SCP), perhaps since network architecture after the intelligent network transition, in the time of need on telecommunications network, increasing IN service, can build a cover service control point (SCP) realization in addition and share processing.This shows, when in the networking, initially introducing, service switching point+service control point (SCP) shows as a cover business platform, converge knot and handle the NP business with this, along with increasing of service switching point in the networking, service switching point+service control point (SCP) just stresses to finish the service control point (SCP) function this moment, and is undertaken alternately by the INAP rules and the service switching point of standard fully, and its original service switching point function still continues to play a role simultaneously; And if service switching point+service control point (SCP) is connected on other service control point (SCP) of higher one-level; make network be implemented to the upgrading of intelligent network; any change need not be done in service switching point+service control point (SCP); just can be used as the service switching point uses; can not cause the waste of resource when upgrading simultaneously, protect the investment of telecommunication department.

The basic function of NP business of the present invention and performance: when end office (EO) judges that a calling is called out for NP, be reported to the service switching point by tandem exchange, when the service switching point judges that according to access code this calling belongs to IN service, send request to the service control point (SCP), the corresponding service logic is searched in the service control point (SCP), and according to the call flow of this service logic control service switching point, during desired data provide in real time by the business datum library facility SDF module in the service control point (SCP).The user data of NP business and business datum are stored in the service control point (SCP), and SMAP safeguards easily by SMAP.The call record of NP business can be stored in the service control point (SCP), is added up and is managed by SMAP SMAP.

NP business processing flow of the present invention is summarized as follows: when caller made a call, caller place office judged that whether caller is number portable user (being called NP user) and shows original number (being called outgoing NP business) when requiring outgoing; If caller is the number portable user and shows original number when requiring outgoing; Then after adding first kind access code on the called number, deliver to number portable platform (NP platform); The number portable platform receives that promptly know behind this call information need be to the original number of called display of calling, number portable this moment platform is judged the called number portable user that whether also is, breathe out after original number is reduced to physical number with called number simultaneously if then calling number is changed into, if not then changing calling number into original number, breathe out after simultaneously called number being reduced to original number; If caller is not the number portable user, though or show original number when being number portable user but failed call outgoing, after then caller makes a call directly with call proceeding to called place office, this innings may be called true place office, also may be number portable user's former place office, this depends on whether called be the number portable user; If through judging called is not the number portable user, then do not need through the number portable platform and directly with call proceeding to called; If through judging that called is the number portable user, deliver to the number portable platform after then adding the second class access code before with called number by the contiguous tandem exchange of above-mentioned called place office or its, the number portable platform finds called physical number after receiving this call information, and by this physical number with call proceeding place office to the called telephone-moving, complete connection.

With instantiation call flow is described below.For ease of describing, make the following hypothesis earlier: the professional tandem exchange of calling NP is 400 to the access code of NP platform, and the professional tandem of outgoing NP is 500 to the access code of NP platform.The party B-subscriber is originally in LS11 office, and its number is 666666, change to LS22 office after, its new digit is 8888888, but externally still uses 666666 after the application calling NP business.

1) NP user is when called, commentaries on classics mode before adopting, and flow process is as follows:

(1) the user A among arbitrary user such as the LS21 dials 6666666 and calls out party B-subscribers in the net, through LS21 → MS1 → LS11 call out to the party B-subscriber originally the LS11 of office;

(2) LS11 office knows calledly when the NP user behind number analysis, obtains 4006401249 numbers before access code 400 is added in called number, with this as the NP called number with the MS1 tandem to the NP platform;

(3) to obtain NP user by the NP number analysis be 8888888 at the physical number of LS22 office to the NP platform, and it is continued to LS22 office as called number, finishes calling.

2) NP user also can adopt back the mode of tearing open when called, and flow process is as follows:

(1) the user A among arbitrary user such as the LS21 dials 6666666 and calls out party B-subscribers in the net, through LS21 → MS1 → LS11 call out to the party B-subscriber former the LS11 of office;

(2) LS11 office judges that behind number analysis called staggering the time for NP user or sky (can not find this number in this office and promptly might be spacing, also might be the NP number), send out spacing information UNN to MS1 office, and discharge LS11 to the speech channel between the MS1, after spacing UNN receives in MS1 tandem exchange, access code 400 is added in obtains 4006401249 numbers before being called out the numbers, as called number;

(3) be connected to the NP platform, judge it is NP user or real spacing by the NP platform; It is 8888888 at LS2 office physical number that the NP platform obtains NP user by the NP number analysis, and this physical number is called out the office to LS22, complete connection as called number.

Flow process when 3) caller is done in the conduct of NP service-user: when user B initiates to call out arbitrarily, to judge this caller be NP user and applied for outgoing NP business by the LS22 office at user B place, and the sign indicating number of breathing out be not 110,119 etc. must the display of calling physical number professional the time, its called number is added that one delivers to the NP platform after inserting prefix 500, after the NP platform is received current calling, calling number is replaced to the NP number, called number with this calling is reduced into the called number exhalation that the user dials then, finishes this time calling.Consider the possibility that has NP customer call NP user, for avoiding on twice to the NP platform, the service control point (SCP) is when inquiry and replacing calling number, also inquire about called number, as called be the NP number, breathe out after then replacing with its physical number, just can directly finish during like this to called office and call out and needn't go up the NP platform again.

Such scheme of the present invention is succeedd in experiment.
