Below in conjunction with accompanying drawing example embodiment of the present invention is explained, to help understanding, they should be thought it only is exemplary comprising the various details of the embodiment of the invention.Therefore, those of ordinary skills will be appreciated that, can make various changes and modification to the embodiments described herein, and can not deviate from scope and spirit of the present invention.Equally, for clarity and conciseness, omitted the description to known function and structure in the following description.In addition, in the situation that do not cause conflict, the various technical characterictics in the following description can make up mutually.

The communication means of the embodiment of the invention can be realized by many communication servers, uses Softswitch technology, and these communication servers can be realized different functions.In the present embodiment, mainly comprise the communication server of two class functions, below be called respectively the first kind communication server and the Equations of The Second Kind communication server.Total plane No. in the present embodiment, the implication of extension number and the relation object of the two are similar to related notion of the prior art.

In the present embodiment, preserve accordingly one or more groups following information: total plane No., a plurality of extension numbers that are subordinated to this total plane No., communication domain name.In the following description, this information is called type I information.In realization, for above-mentioned total plane No. and the domain name of communicating by letter, total plane No. and the domain name of communicating by letter of normally same organization (company for example below describes as an example of company example, and namely the communication domain name here is the communication domain name of company).In the present embodiment, also preserve accordingly one or more groups following information: total plane No. and the domain name of preserving the first kind communication server of this total plane No..In the following description, this information is called Equations of The Second Kind information.

Extension set in the present embodiment is internet terminal, and signalling adopts session to send out beginning agreement SIP(Session Initiation Protocol).Transfer of data can adopt RTP (Realtime Transport Protocol, RTP) and RTP Control Protocol (RTP Control Protocol, RTCP) via the Internet (Internet).

When extension set makes a call, provide the communication domain name of extension number and extension set place company.Can think that extension set provides the information of shape such as 1006 example.com, wherein 1006 are extension numbers, example.com is the communication domain name of company.

The first kind communication server is being received dialogue-based beginning agreement of caller extension set, after the calling by the Internet initiation, judge according to communication domain name, called number in type I information and this calling, belong to same exchange in the situation that called number is extension number and called extension set and caller extension set, transfer the call to called extension set.In the situation that called number is not extension number, transfer the call to the Equations of The Second Kind communication server, by the Equations of The Second Kind communication server according to Equations of The Second Kind information and called number, determine to preserve the first kind communication server of called number, then transfer the call to this first kind communication server, carry out next step operation by this first kind communication server prompting caller extension set.

The calling that extension set is initiated be by DNS with our company's communication domain name analysis to the corresponding communication server.Can adopt the existing technology relevant with the DNS service to realize this parsing.Omitted the resolving of dns server, but had DNS in the real system in clear, the following description and accompanying drawing in order to describe concise and to the point and to illustrate.

For example, the first kind communication server (hereinafter to be referred as making rs1) that a domain name is arranged is rs1.example1.com has read the type I information of listing with the form of table 1.The Equations of The Second Kind communication server that other has a domain name is bs1.example.com (hereinafter to be referred as making bs1) has read the Equations of The Second Kind information of listing with the form of table 2.

Table 1

Table 2

Total plane No.	The domain name of the first kind communication server
		63325***	rs1.example1.com
82226***	rs2.example1.com
		……	……

In the table 1, total plane No. 63225600 is corresponding to extension number 1001 to 1050, simultaneously corresponding to domain name d.exampled.com.Below the implication of correspondence in each table similar, namely be in correspondence with each other content with the content of delegation.Total plane No. in the table 2 has adopted the expression mode of number segment, and for example 63325*** represents 1000 telephone numbers of from 63325000 to 63325999.In the following description, extension set is with the name of its extension number, and for example extension number is that 1001 extension set just is called extension set 1001.Exchange is also with its total plane No. name.

When extension set 1001 is called out extension set 1002, rs1 determines that according to the figure place of called number 1002 it is extension number, table look-up 1 affirmation extension set 1002 corresponding to domain name q.example1.com, the domain name that provides when calling out with extension set 1001 is identical, think that namely extension set 1001 and extension set 1002 belong to same exchange, so transfer the call to called extension set 1002.

If extension set 1001 is called out extension set 8001, when operation, according to usual way, dial first total plane No. 63236700, namely call out first total plane No., what this moment, rs1 was that the figure place of total plane No. confirm to call out according to called number is not extension number, calling is given to the Equations of The Second Kind communication server that self connects.In the present embodiment, a plurality of first kind communication servers are connected with an Equations of The Second Kind communication server, and each first kind communication server only is connected with an Equations of The Second Kind communication server.For example rs1 is connected with bs1, then the calling of extension set 1001 calling exchanges 63225700 is transferred to bs1 by rs1, bs1 is corresponding with rs1 according to the content check 63225700 of table 2, so transfer the call to rs1, is the information that extension set 1001 sends next step operation by rs1 to caller.In the table 2 be 63225700 these numbers corresponding to this domain name of rs1.example1.com, just think that exchange 63225700 is corresponding to first kind communication server rs1.The implication of following " correspondence " similarly.

Rs1 sends the information of next step operations to caller extension set 1001, can adopt common interactive voice answering IVR(Interactive Voice Response) mode realizes; Rs1 can also check first whether called extension set 8001 is online in addition, if, then point out caller to dial extension number 8001, otherwise opening voice mailbox or call out transfer by predetermined manner.

In the above example, caller extension set 1001 and called extension set 8001, their general number is preserved by same first kind communication server rs1.In the view of the user, the rs1 performance becomes two communication servers, namely has two virtual communication servers, serves respectively exchange 63225600 and 63225700.That is to say, if these two exchanges that exchange is two companies, these two companies can use same communication server equipment so.In another case, the caller extension set is realized by the different first kind communication servers from the function that called extension set is distinguished affiliated exchange, for example extension set 1001 is called out certain extension set of exchange 82226001, the Equations of The Second Kind communication server is after receiving the calling that the first kind communication server shifts at this moment, and check table 2 is confirmed to need calling is transferred to the first kind communication server rs2 that domain name is rs2.example1.com.But as broad as long with the first situation In the view of the user, all be to have called out first exchange, call out again extension set after receiving prompt tone.

That is to say, according to the technical scheme of the present embodiment, can be provided by a plurality of first kind communication servers service of enterprise-level telephone exchange system to a plurality of companies, wherein each first kind communication server can provide above service to one or more companies.Can find out that in fact this consisted of a kind of communication system, in the following description, it is called " cloud telephone exchange system ", the first kind communication server, the Equations of The Second Kind communication server are arranged in this cloud telephone exchange system, also has storage server system, and alternatively, this cloud telephone exchange system can also comprise the 3rd class communication server that hereinafter will introduce.

Storage server system is the computer cluster that database software is arranged by a plurality of operations, can preserve type I information and Equations of The Second Kind information, and the 3rd class that hereinafter will introduce, the 4th class and the 5th category information, specifically can adopt the technology of cloud storage to realize improving reliability.At storage server system, can adopt a large amount of various dissimilar memory devices, gather collaborative work by application software, data storage and Operational Visit function externally are provided jointly.Similarly, also comprise first kind communication server cluster and Equations of The Second Kind communication server cluster in the cloud telephone exchange system.Take first kind communication server cluster as example, which first kind communication server to be realized the service of which exchange by, then be that the particular content of the type I information that read from storage server system by the first kind communication server decides.For example certain first kind communication server has read the information in the table 1, then this first kind communication server is realized is service to total plane No. 63225600 and 63225700, only read the corresponding extension number of total plane No. 63225600 in the table 1 and the domain name of communicating by letter of company, the service to total plane No. 63225600 just only is provided.Be engaged in for more exchange liveries thereby in realization, can read more information, that is to say can the flexible configuration first kind communication server service object and service range.And if a certain the first kind communication server break down, then its function can be replaced by other communication servers fully, and this helps to improve reliability of service.Similarly, each Equations of The Second Kind communication server monomer in the Equations of The Second Kind communication server cluster also can be realized different service objects by the Equations of The Second Kind information that reads different particular contents.

Certainly, also can utilize the memory space of the first kind communication server and Equations of The Second Kind communication server inside to realize the storage of type I information and Equations of The Second Kind information and the 3rd class that hereinafter will introduce, the 4th class and the 5th category information.Can adopt equally the technology of cloud storage to realize.But in order to improve the reliability of system, had better adopt communication server equipment in addition to realize memory function.

In addition, in realization, can be safeguarded by the professional by the communication system that the first kind communication server and the Equations of The Second Kind communication server consist of, company only need provide terminal equipment for example the internet terminal of IP phone machine or software form can enjoy the enterprise-level telephone exchange system, can have neatly the extension set that quantity does not wait.In external when wiring of company, only need be laid the circuit that connects for the Internet, need not optical cable, the circuit such as telephone wire.When Enlargement of Enterprise Scale, the cloud telephone exchange system can capacity be supplied the extension set number, and from start to finish enterprise all need not to buy voluntarily and the maintain communication services device, and this has saved the manpower and materials of company undoubtedly greatly.And the cloud telephone exchange system of being safeguarded by the special messenger can have the configuration of more optimizing, and the expansion of system is also very convenient, thereby so that the performance of each enterprise-level telephone exchange system is better.

It can also be seen that from the above description, the enterprise-level exchange service that the communication system that is made of the first kind communication server and the Equations of The Second Kind communication server provides, what can realize is conversation between these exchanges and the extension set thereof, transfer of data during conversation is via the Internet, this so that cost of the phone call might reduce, in the higher situation of the cost of the phone call that particularly in reality, causes owing to reasons such as monopolizations, another selection that the enterprise-level exchange service in the present embodiment becomes each company when having a telephone installed.Certainly the enterprise-level exchange service in the present embodiment also can be a plurality of independent personal users (i.e. so-called " casual household ") service, this moment, each personal user had total plane No. and the extension number of oneself, everyone extension number is different, and a plurality of people may have identical total plane No..So the enterprise-level exchange service in the present embodiment also is the another selection of installing a telephone for the individual of nonbusiness.

Certainly it can also be seen that from the above description, above-mentioned company and individual's conversation scope is the inside in the communication system that is made of the first kind communication server and the Equations of The Second Kind communication server.For the communication system with the outside contacts, the present embodiment also provides relevant technical scheme, below is explained.

In the present embodiment, for the cloud telephone exchange system, outside communication system can be divided into two classes, is respectively to support and do not support session to send out the communication system of beginning agreement (Session Initiation Protocol, SIP).Below this two classes communication system is called respectively first kind communication system and Equations of The Second Kind communication system.The technical scheme that communicates with first kind communication system at first is described.

Storage server system is preserved following information accordingly: next generation network (the Next Generation Network under first kind telephone number, the first kind telephone number in the communication system, NGN) domain name of gateway, these information are called the 3rd category information hereinafter.The first kind telephone number here is to support session to send out the telephone number in the communication system of beginning agreement.The Equations of The Second Kind communication server is connected with the NGN gateway, can adopt the technology of common operator docking to finish herein, wherein will preserve some number docking address and protocol specifications.Certainly, according to the needs of network configuration, many Equations of The Second Kind communication servers are arranged in the cloud telephone exchange system, the NGN gateway with different regions (dividing with trunk code) is connected separately.

Extension set can be called out first kind telephone number, in this case, for the first kind communication server, receiving dialogue-based beginning agreement of caller extension set, after the calling by the Internet initiation, judge according to type I information and called number, in the situation that called number is not extension number, transfer the call to the Equations of The Second Kind communication server, by the Equations of The Second Kind communication server according to the 3rd category information and called number, confirm that called number is first kind telephone number, then transfer the call to NGN gateway corresponding to called number.

For example, Equations of The Second Kind communication server bs1 has read the 3rd category information of listing with the form of table 3 from storage server system.

Table 3

Telephone number	The domain name of the Equations of The Second Kind communication server
		1311618****	wg1.example2.com
1330720****	wg2.example2.com
		……	……

Adopted equally the expression mode of number segment in the table 3.For example work as extension set 1001(referring to table 1) calling telephone number 13116180001, it is not extension number that rs1 judges it according to the figure place of this number, then bs1 is given in calling, bs1 is the NGN gateway wg1 of wg1.example2.com corresponding to domain name according to this telephone number of content check of table 3, so this gateway is given in calling, later operation just gets final product by the conventional treatment mode in the communication system under this gateway.

Extension set also can accept to come from the calling of first kind communication system.This is called out via behind the NGN gateway arrival Equations of The Second Kind communication server, the Equations of The Second Kind communication server is according to the total plane No. in Equations of The Second Kind information and this calling, determine to preserve the first kind communication server of this total plane No., then transfer the call to this first kind communication server, carry out next step operation by this first kind communication server prompting caller.

For example telephone number 13307201000 is called out extension set 8001, dials first exchange 63225700, calls out via wg2.example2.com and arrives bs1, the bs1 content shown in 2 of tabling look-up, that confirm exchange 63225700 correspondences is rs1, then calling is transferred to rs1, carries out subsequent treatment by rs1.

For the Equations of The Second Kind communication system, namely do not support the communication system of SIP, the cloud exchange need to increase by the 3rd class communication server when communicating with it, be used for carrying out the signaling conversion between the Equations of The Second Kind communication server and above-mentioned Equations of The Second Kind communication system.Like this, the user of cloud telephone exchange system just can converse with the terminal of Equations of The Second Kind communication system, for example with PSTN (Public Switched Telephone Network, PSTN) in telephone relation.

For this reason, storage server system is also preserved following information accordingly: the domain name of Equations of The Second Kind telephone number, the 3rd class communication server below is called the 4th category information.The Equations of The Second Kind telephone number here is the telephone number in the Equations of The Second Kind communication system.For example, Equations of The Second Kind communication server bs1 has read the 4th category information of listing with the form of table 4.

Table 4

Telephone number	The domain name of the 3rd class communication server
		8566***	relay1.example3.com
5310***	relay2.example3.com
		……	……

After extension set makes a call to the Equations of The Second Kind communication system, the first kind communication server is received this calling, then judge according to type I information and called number, in the situation that called number is not extension number, transfer the call to the Equations of The Second Kind communication server, by the Equations of The Second Kind communication server according to the 4th category information and called number, confirm that called number is the Equations of The Second Kind telephone number, then transfer the call to the 3rd class communication server corresponding to called number, transferred the call to by the 3rd class communication server and connectedly do not support session to send out the communication system of beginning agreement.

For example, extension set 1050 calling telephone numbers 85661100, rs1 confirms that according to the figure place of telephone number 85661100 it is not extension number, then be transferred to bs1, bs1 confirms that according to table 4 85661100 is Equations of The Second Kind telephone numbers, and corresponding to the 3rd class communication server relay1, its domain name is relay1.example4.com.So bs1 is transferred to relay1 with calling.Next by relay1 calling is transferred to the relevant device of Equations of The Second Kind communication system, subsequent treatment namely gets final product by the usual manner in the Equations of The Second Kind communication system.

The extension set of the terminal of Equations of The Second Kind communication system in also can the calling cloud telephone exchange system.For this reason, storage server system is also preserved following information accordingly: the domain name of total plane No., the Equations of The Second Kind communication server below is called the 5th category information.For example, the 3rd class communication server relay1 has read the 5th category information of listing with the form of table 5.

Table 5

Total plane No.	The domain name of the Equations of The Second Kind communication server
		63325***	bs1.example.com
82226***	bs1.example.com
		58041***	bs2.example.com
……	……

The 3rd class communication server receive come from the calling of Equations of The Second Kind communication system for total plane No. after, according to the 5th category information and called total plane No., determine the Equations of The Second Kind communication server that this total plane No. is corresponding, then this calling is transferred to this Equations of The Second Kind communication server; This Equations of The Second Kind communication server is according to Equations of The Second Kind information and called total plane No., determine to preserve the first kind communication server of this total plane No., then transfer the call to this first kind communication server, carry out next step operation by this first kind communication server prompting caller.

For example, telephone number 53103333 makes a call to extension set 1050, dial first exchange 63225600, the 3rd class communication server finds bs1 according to the content of number 63225600 and table 5, then transfer the call to bs1, bs1 finds rs1 according to the content of number 63225600 and table 2 again, transfers the call to rs1 again.
