The method provides a virtual number assigned independently for a user, who has an actual number. A central server does the conversion between the virtual number and the actual number. When the actual number is changed, the mapping table stored in the central server is modified. Thus, the virtual number is unchanged so as to guarantee the unique, persistance, and removability. The function of virtual service provider and be provided through assigning virtual number. It is easy to solve the voice communication issue in broadband subzone, where there is no number resource, through the combination between the virtual number and Ethernet telephone.
Description
Technical field
The present invention relates to the method for fixed-line subscriber number in the communication network, the implementation method of the unified user number of particularly a kind of combining telecommunication net and ip voice.
Background technology
Traditional speech communication mainly is to realize by PSTN (Public Switch Telephone Network public switched telephone network) and PLMN (Public Land Mobile Network public land mobile net) network, i.e. phone (Phone) on our common meaning; Its network configuration as shown in Figure 1.
Mobile phone inserts mobile switch by the mobile base station, and the direct access switch of landline telephone carries out the transmission of signaling and voice then by the PSTN/PLMN network.In the PSTN/PLMN network, be actually by repeatedly exchanging the talking connection process of finishing a time, whole PSTN/PLMN network also is to be formed by connecting by very many switches.
Development along with IP network and multi-media communication, IP network develops increasingly, application on the IP network is more and more, the fusion of IP network and PSTN network has become trend of the times, in order to merge the voice application on IP network and the PSTN network, International Standards Organization has proposed following soft switch (Softswitch) framework, as shown in Figure 2.Wherein:
SG: SGW (Signal Gateway), finish on the PSTN the signaling of signaling (for example: Signaling System Number 7, R2 signaling, isdn signaling) on the IP network (for example: BICC, conversion SIGTRAN).
MG: media gateway (Media Gateway), finish on voice (for example: T1, E1) the road IP network on the PSTN voice (for example: conversion RTP/RTCP).
SoftSwitch: soft switch, finish the exchange of the voice signaling on the IP network.For the switch on the PSTN, be exactly the switch on the IP network, only it only finishes the exchange of signaling, does not carry out the exchange of voice, and the exchange of voice is finished by equipment such as routers.
SoftPhone: software I P calling customer terminal is a software that operates on the user's computer, finishes speech communication by the sound card of computer.
EthernetPhone: the Ethernet Phone machine, it is the telephone set that can directly receive on the Ethernet, is similar to plain old telephone, but Ethernet interface is arranged, and can directly use on IP network.
MS: media server (Media Server) provides the automation services of the voice on the IP network, for example: voice mail, telephone bank.
The core of soft-exchange construction is to have finished PSTN speech communication combination on the IP network by providing of SoftSwitch equipment, makes that the equipment on PSTN and the IP network can be called out and converse mutually.
Soft-exchange construction provides the solution of equipment, but do not provide the solution in the operation, in soft switch, exist one very distinct issues be exactly: the equipment on the IP network does not have the number on traditional PSTN/PLMN network, this just makes traditional PSTN/PLMN user bother very much when dialing user on the IP network, never a unified solution.
Solution at this problem is the ENUM motion of IETF at present, and the core concept of this motion is to reuse original telephone number, makes original telephone number can find the subscriber equipment on the IP network.The design philosophy of this motion is as follows:
If user's telephone number is 0086-10-12345678, this telephone number is transformed into the mode of domain name: 8.7.6.5.4.3.2.1.0.1.6.8.enum.arpa, then this list item is joined in the domain name mapping tabulation of DNS service, the IP address of 8.7.6.5.4.3.2.1.0.1.6.8.enum.arpa correspondence is user device IP address and the port on the IP network.This motion has solved the mapping of the plain old telephone number subscriber equipment on the IP network, but use dumb, when user's telephone number changes or during the IP network equipment variations, needs to revise the data of DNS, but the data of DNS are not suitable for frequent change, use cumbersome.
Summary of the invention
The object of the present invention is to provide the implementation method of the unified user number of combining telecommunication net and ip voice, make regardless of the user at the speech ciphering equipment that uses PSTN/PLMN, also be to use the speech ciphering equipment on the IP network, can both carry out mutual conversation easily, and when user's telephone number or IP network equipment change, can very easily make amendment.
Method of the present invention comprises:
For the network user who has physical number in telecommunications network and the IP network distributes independently virtual-number unitedly;
In IP network, set up central server, at least the mapping relations table that is made of the network user's physical number and virtual-number is stored in the central database of this central server, and between the signaling switching equipment of described central server and IP network, sets up access interface;
Revise the call routing table on the switch in the telecommunications network, the calling of relevant virtual-number all is routed to the signaling switching equipment of IP network;
When from telecommunications network calling virtual-number, switch routes the call to the signaling switching equipment of IP network according to call routing table, this signaling switching equipment obtains called subscriber's physical number according to this virtual-number by access interface from central database, and this physical number is made a call.
The effect of the inventive method is: by increase the central database treatment system on the basis of soft switch (Softswitch) framework, (1) provides an independent allocation virtual-number for each user, and the function of virtual operator is provided by the distribution of virtual-number; (2) virtual-number is finished conversion with physical number by central server, can keep virtual-number constant always like this, has guaranteed that user's number is unique, lasting, mobility; (3), solve the speech communication problem of the broadband cell that does not have number resource by the combination of virtual-number and Ethernet Phone.

Embodiment
With reference to figure 3: the telecommunications network user by PSTN/PLMN with direct access IP network.SGW (Signal Gateway:SG) is finished the signaling on the PSTN/PLMN, for example: Signaling System Number 7, R2 signaling, isdn signaling, the signaling on the IP network is (for example: BICC, conversion SIGTRAN).Media gateway (Media Gateway:MG) finish on the PSTN the voice of voice (for example: T1, E1) on the IP network (for example: conversion RTP/RTCP).Soft switch (SoftSwitch) equipment is finished the exchange of the voice signaling on the IP network, for the switch on the PSTN, soft switch (SoftSwitch) equipment is exactly the switch on the IP network, only it only finishes the exchange of signaling, do not carry out the exchange of voice, the exchange of voice is finished by equipment such as routers.Software I P phone (SoftPhone) client is a software that operates on the user's computer, finishes speech communication by the sound card of computer.Ethernet Phone machine (EthernetPhone), it is the telephone set that can directly receive on the Ethernet, is similar to plain old telephone, but Ethernet interface is arranged, and can directly use on IP network.Media server (MediaServer:MS) provides the automation services of the voice on the IP network, for example: voice mail, telephone bank.
Each network user who has physical number in PSTN network, PLMNIP network and IP network is had a virtual-number independently by unified distribution.Simultaneously in IP network, set up central server, in this server, set up central database, and the mapping relations table is stored in this central database with setting up one by one between user's virtual-number and its physical number.This mapping table also can include user's out of Memory, as name, address and rights of using etc.Central database access interface in setting up between central database and Softswitch adopts Light Directory Access Protocol (Light Directory AccessProtocol between Softswitch and the central database; LDAP) carry out data access.Increase new call routing table item in the call routing table in the switch of communication network, this routing table all is routed to the calling of virtual-number on the Softswitch, obtains corresponding physical number by Softswitch according to virtual-number from central database.
Dial a virtual-number 0000000001 as a PSTN user, the network appliance address of this virtual-number correspondence is 1.1.1.1, and its mapping relations table is stored in the central database.Its basic call flow is as follows:
1:PSTN user dials virtual-number 0000000001;
Switch on the 2:PSTN is according to call routing table, this calling is routed on the SoftSwitch handles:
3:SoftSwitch gives the database of the centre in the central server virtual-number 0000000001 by ldap protocol;
4: it is an IP network equipment that the central data base system inquiry obtains the called of 0000000001 number correspondence, and its current IP address is 1.1.1.1.Central database is given SoftSwitch 1.1.1.1;
5:SoftSwitch makes a call to the 1.1.1.1 address;
6: behind the called off-hook, both sides begin conversation.
In actual use, the central server of setting up in IP network can be a plurality of, and is based upon different zones according to the distribution situation of geographical conditions, administrative region and communication flows.
For user's virtual-number, can be according to user's needs, the user of a certain physical number also can distribute a plurality of virtual-numbers, and each virtual-number is all corresponding to its physical number, and described physical number can be physical number or actual IP address.The function of virtual operator is provided by the distribution of virtual-number; Virtual-number can distribute according to user's demand, for an enterprise network internal user, virtual-number can adopt employee's job number, can adopt job number directly to carry out audio call and conversation like this between the enterprise network internal user, the employee of enterprise outside can directly dial the employee after having dialed exchange job number finds the employee, and not needing to be concerned about employee's particular geographic location, this is just particularly useful to the enterprise that a geographical position disperses very much; For the telecommunications network user, virtual-number can adopt Random assignment or the paid mode of buying, and after the user obtains the right to use of virtual-number, can keep all the life.By the distribution of virtual-number and the equipment support of soft switch, just can set up pseudo telecommunications operator, like this for the user provides speech communication service and value-added service.
Virtual-number is finished conversion with physical number by central server, can keep virtual-number constant always like this, has guaranteed that user's number is unique, lasting, mobility; When realizing, preserve all users' information in the Database Systems of central server, adopt Light Directory Access Protocol (LDAP) to carry out the visit of data between SoftSwitch and the central server, SoftSwitch obtains user's physical number or IP address by central server; Central server provides a WEB page simultaneously, for its user profile of user's modification.When user profile changed, the user only needed to revise by the WEB page and gets final product.By the providing of central server, just simply finished the mapping of PSTN/PLMN number to IP network equipment like this, its mapping relations can be revised easily simultaneously.Because all user's data all are kept in the central database, the number that has so just guaranteed all users all is unique; Because the mapping relations of virtual-number and plain old telephone number can be revised, the user changes and revises behind plain old telephone number or the IP network equipment that mapping relations just can solve, and has so just guaranteed the persistence of Subscriber Number; Because user's number is the virtual-number that is kept in the database, it doesn't matter with actual physical location, and no matter the user can use this number where always, has so just guaranteed the mobility of Subscriber Number.
By the combination of virtual-number and Ethernet Phone, also can solve the speech communication problem of the broadband cell that does not have number resource.Serious problems of broadband cell are exactly after adopting the broadband at present, if do not lay traditional telephone wire, then just do not have number resource, if lay telephone wire, then have the problem of equipment waste.Adopt method of the present invention, provide just very easy head it off of a virtual-number by the user who gives each broadband cell, concrete scheme is: install a SIM card on Ethernet Phone additional, preserve user's virtual-number and relevant information on the SIM card, after installing SIM card, Ethernet Phone is registered to central data base system by Ethernet automatically, and log-on message obtains from SIM card.When the user moves, only need SIM card taken away and get final product.Other user just can converse with it by the virtual-number of dialing this user.So just do not need to have laid traditional telephone wire.
Fig. 4 has further shown the realization of the present invention in enterprise network:
In Beijing, a branch company is arranged as an enterprise headquarters respectively, originally all use PBX to connect inner phone in Shanghai and Shenzhen.As follows to the network rebuilding now: in Beijing, Shanghai and Shenzhen increases a GW (GateWay gateway) respectively, because enterprise-level application, capacity is less, there is no need to use these jumbo equipment of SG and MG, adopts GW just can meet the demands.Each GW couples together by router and DDN.Set up central server and Softswitch (SoftSwitch) in Beijing, employee's job number is directly used in the distribution of virtual-number, and sets up the mapping table between its job number and the physical number and be stored in the central database of central server.Revise the routing table of the PBX in Beijing, Shanghai, Shenzhen, the calling that makes all dial employee's job number is routed directly on the Softswitch.So not only the employee of intra-company does not need to be concerned about the other side's particular location, directly dials called job number and just can carry out communication with the other side; And the external staff of company do not need to be concerned about employee's particular location yet, only need dial any one the other side's exchange, and the job number that changes the employee then is just passable.
Fig. 5 has further shown the realization of the present invention in telecommunications network:
Telephone subscriber of Pekinese and cellphone subscriber directly insert IP network by the PSTN/PLMN of Pekinese, and same, the telephone subscriber in Shanghai and cellphone subscriber also directly insert IP network by the local PSTN/PLMN in Shanghai.10 item sign indicating numbers with 233 number of being head are adopted in the distribution of virtual-number, all 233 are all transferred on the Softswitch (SoftSwitch) for the calling of number head, Softswitch and central database obtain user's more specific location information alternately, make a call to particular location then.This mode is to the detail of the IP phone of user's shielding, the user can be by using with the identical mode of use plain old telephone, because transmit by IP network the centre, has saved expense greatly, do not need to be concerned about called subscriber's particular location simultaneously yet and answer mode.Called subscriber's call information is customized by WEB voluntarily by the called subscriber, is a personalized fully speech communication mode.
