The communication means of the embodiment of the present invention can be realized by the multiple stage communication server, and application Softswitch technology, these communication servers can realize different functions.In the present embodiment, mainly comprise the communication server of two class functions, be below called 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, one or more groups following information is preserved accordingly: total plane No., the multiple extension numbers being subordinated to this total plane No., communication domain name.In the following description, this information is called type I information.In the implementation, for above-mentioned total plane No. and the domain name that communicates, total plane No. of normally same organization (such as company, is described for company below, and namely communication domain name is here the communication domain name of company) and the domain name that communicates.In the present embodiment, also preserve one or more groups following information accordingly: the domain name of the first kind communication server of total plane No. and this total plane No. of preservation.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, via the Internet (Internet), can adopt RTP (Realtime Transport Protocol, RTP) and RTP Control Protocol (RTP Control Protocol, RTCP).

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 as 1006 example.com, wherein 1006 is extension numbers, and example.com is the communication domain name of company.

The first kind communication server is receiving caller extension set dialogue-based beginning agreement, after the calling initiated by the Internet, judge according to the communication domain name in type I information and this calling, called number, when called number is extension number and called extension set and caller extension set belong to same exchange, transfer the call to called extension set.When 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 the first kind communication server preserving called number, then transfer the call to this first kind communication server, point out caller extension set to carry out next step by this first kind communication server and operate.

Extension set initiate calling be by DNS by our company's communication domain name analysis on the corresponding communication server.Can adopt and existingly serve relevant technology to realize this parsing with DNS.In order to describe concise and to the point and illustrate in clear, following description and accompanying drawing, to eliminate the resolving of dns server, but there is DNS in real system.

Such as, a domain name is had to be that the first kind communication server (hereinafter referred to as rs1) of rs1.example1.com have read the type I information listed with the form of table 1.A domain name is separately had to be that the Equations of The Second Kind communication server (hereinafter referred to as bs1) of bs1.example.com have read the Equations of The Second Kind information listed 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 table 1, total plane No. 63225600 corresponds to extension number 1001 to 1050, corresponds to domain name d.exampled.com simultaneously.The implication of the correspondence in following table is similar, is namely content in correspondence with each other with the content of a line.Total plane No. in table 2 have employed the representation of number segment, and such as 63325*** represents 1000 telephone numbers from 63325000 to 63325999.In the following description, extension set is named with its extension number, such as extension number be 1001 extension set be just called extension set 1001.Exchange is also with its total plane No. name.

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

If extension set 8001 called out by extension set 1001, when operating according to usual way, first to dial total plane No. 63236700, namely first calling out total plane No., what now rs1 confirmed calling according to the figure place of called number and total plane No. is not extension number, and the Equations of The Second Kind communication server self connected is given in calling.In the present embodiment, multiple first kind communication server is connected with an Equations of The Second Kind communication server, and each first kind communication server is only connected with an Equations of The Second Kind communication server.Such as rs1 is connected with bs1, the calling that then exchange 63225700 called out by extension set 1001 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, sends next step information operated by rs1 to caller and extension set 1001.Be that 63225700 these numbers correspond to this domain name of rs1.example1.com in table 2, just think that exchange 63225700 corresponds to first kind communication server rs1.The implication of following " correspondence " is similar.

Rs1 sends the information of next step operation to caller extension set 1001, and common interactive voice answering IVR (Interactive Voice Response) mode can be adopted to realize; Rs1 first can also check that whether called extension set 8001 is online in addition, if so, then points out caller dials extension number 8001, otherwise opening voice mailbox or carry out call forwarding by predetermined manner.

In 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 user, rs1 performance becomes two communication servers, and the communication server that namely existence two is virtual, serves exchange 63225600 and 63225700 respectively.That is, if the exchange of these two exchange Shi Liangge companies, so this Liang Ge company can use same communication server equipment.In another case, the function of caller extension set and the exchange belonging to called extension set difference is realized by the different first kind communication servers, certain extension set of exchange 82226001 called out by such as extension set 1001, now the Equations of The Second Kind communication server is after the calling receiving the transfer of the first kind communication server, and call forwarding to domain name need be the first kind communication server rs2 of rs2.example1.com by check table 2 confirmation.But as broad as long with the first situation In the view of user, be all first have called exchange, after receiving prompt tone, call out extension set again.

That is, according to the technical scheme of the present embodiment, can be provided the service of enterprise-level telephone exchange system to multiple company by multiple first kind communication server, wherein each first kind communication server can provide above service to one or more company.Can find out that in fact this constitute a kind of communication system, in following description, call it as " cloud telephone exchange system ", the first kind communication server, the Equations of The Second Kind communication server is had 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 hereinafter will introduced.

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

In addition, in the implementation, the communication system be made up of the first kind communication server and the Equations of The Second Kind communication server can be safeguarded by professional, company only need provide the internet terminal of terminal equipment such as IP telephone machine or software form can enjoy enterprise-level telephone exchange system, can have the extension set that quantity does not wait neatly.Company external wiring time only need lay for the Internet connect circuit, need not the circuit such as optical cable, telephone wire.When Enlargement of Enterprise Scale, cloud telephone exchange system can enough supply extension set numbers, and from start to finish enterprise is all without the need to buying voluntarily and maintain communication services device, and this saves the manpower and materials of company undoubtedly greatly.And the cloud telephone exchange system safeguarded by special messenger can have the configuration more optimized, the expansion of system is also very convenient, thus makes the performance of each enterprise-level telephone exchange system more excellent.

It can also be seen that from the above description, the enterprise-level attendant service that the communication system be made up of the first kind communication server and the Equations of The Second Kind communication server provides, what can realize is call between these exchanges and extension set thereof, transfer of data during call is via the Internet, this makes cost of the phone call likely reduce, the cost of the phone call particularly caused due to reasons such as monopolizations in reality is higher, another becoming when phone is installed by each company of the enterprise-level attendant service in the present embodiment is selected.Enterprise-level attendant service in certain the present embodiment also can be multiple independent personal user (i.e. so-called " casual household ") service, now each personal user has total plane No. and the extension number of oneself, everyone extension number is different, and multiple people may have identical total plane No..So enterprise-level attendant service in the present embodiment for nonbusiness individual be also the another selection of installing a telephone.

Certainly it can also be seen that from the above description, the activity extent of above-mentioned company and individual is in the inside of the communication system be made up of the first kind communication server and the Equations of The Second Kind communication server.In order to contact with the communication system of outside, the present embodiment also provides relevant technical scheme, is below explained.

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

Storage server system preserves following information accordingly: next generation network (the Next Generation Network in communication system belonging to first kind telephone number, first kind telephone number, NGN) domain name of gateway, these information are called the 3rd category information hereinafter.Here first kind telephone number supports that the telephone number in the communication system of beginning agreement is sent out in session.The Equations of The Second Kind communication server is connected with NGN gateway, and the technology that common operator can be adopted to dock herein has been come, and wherein will preserve some numbers docking address and protocol specification.Certainly, according to the needs of network configuration, in cloud telephone exchange system, there is the multiple stage Equations of The Second Kind communication server, be connected with the NGN gateway of different regions (dividing with trunk code) separately.

Extension set can call out first kind telephone number, in this case, for the first kind communication server, receiving caller extension set dialogue-based beginning agreement, after the calling initiated by the Internet, judge according to type I information and called number, when 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 the NGN gateway that called number is corresponding.
