The method comprises: using the E.164 code to identify the medium resource in the medium resource server of network and building the mapping relation between the E.164 code and the medium resource; the soft exchange or the application server uses needed medium resource to inquire said mapping relation and get the E.164 code relative to said medium resource, and calls this E.164 code; the network device routes the calling to relative medium resource server which will supply the medium resource relative to said E.164 code to the gateway of medium.
Description
Technical field
The present invention relates to next generation network (NGN) technology, relate in particular to a kind of method of in next generation network, operating media resource.
Background technology
Under the NGN network, the operation to playback, media resource such as collect the digits at present mainly contains following method:
Method one: consult shown in Figure 1, pass through MGCP/H248, adopt Media Gateway Controller (MGC)/media gateway (MG) framework, Media Resource Server is presented as the MG parts, by the playback in soft switch (being MGC) the control operation flow, process collects the digits.Because application server can only provide the Session Initiation Protocol intercommunication, therefore the control to MRS can only realize that (Session Initiation Protocol, resource request SIP) is converted to the resource operation of MGCP Session initiation Protocol by soft switch by soft switch.Though this method is ripe, and obtains extensive use, in processing procedure, need extra a large amount of conversion work that increases.
Method two: soft switch or application server and MRS are divided into two relatively independent parts by Session Initiation Protocol.Consult shown in Figure 2ly, to the operation of resource, be converted into calling, and set up the mapping relations of SIPURL to media resource to SIP URL.This kind method does not have unified standard on the identification method of resource.
Because method two to the medium resource identification disunity, causes different MRS to have problems when docking with soft switch or application server (AS).For example, when MRS uses non-number mark media resource, during as the domain name mode of SPECIALTONE@MRS.HUAWEI, can't dock with it for some soft switch of not supporting the domain name mode to call out.In addition, when a MRS docks with a plurality of soft switch or application server simultaneously, media resource is not had unique identification method, bring extra management workload can for the uniqueness of resource identification yet.And MRS is when the cross-domain application of existing network, also will solve the problems such as route that SIP calls out, and causes media resource to share difficulty.
Summary of the invention
The object of the present invention is to provide a kind of in next generation network the method for operation media resource, have not manageability and share the problem of difficulty at the media resource of whole network of media resource in the prior art to solve.
For addressing the above problem, the invention provides following technical scheme:
A kind of method of in next generation network, operating media resource, this method is:
A, adopt the media resource on the Media Resource Server in the number mark network E.164, and set up the mapping relations between number and the resource, described mapping relations are configured in soft switch and the application server;
The media resource that B, soft switch or application server utilization need is inquired about the E.164 number that described mapping relations obtain this media resource correspondence, and to this E.164 number make a call;
C, the network switching equipment route the call to the purpose Media Resource Server, and soft switch simultaneously or application server notice need the media gateway receiving media resource of media resource, specify the media gateway that needs media resource in the described calling,
Media Resource Server and described media gateway are set up media channel, and
Media Resource Server E.164 number corresponding resource sends to described media gateway by media channel.
According to said method:
Calling to described E.164 number utilizes Session initiation Protocol SIP to initiate.
When required media resource was playback operation, Media Resource Server was done medium by soft switch and media gateway and is consulted to set up media channel.
When soft switch or application server when E.164 there is the receiving number operation in the calling of number, Media Resource Server sends back soft switch or application server with the number of receiving by Session Initiation Protocol.
The present invention has realized the separate configurations of media resource and soft switch in the NGN network, and can be in whole net abundant share media resource, can reduce the quantity of Media Resource Server significantly.In addition,, simplified the uniqueness management of resource identification, made that unified the use becomes possibility in whole net because utilized existing E.164 number planning.

Embodiment
The present invention adopts the media resource on the number mark Media Resource Server E.164, make media resource in the next generation network (NGN) and public switch telephone network (PSTN) go up existing media resource and can in whole network, unify sign, realize the unified management and the unified use of media resource.
When adopting E.164 the number mark media resource, this number should use number different with existing, to guarantee the uniqueness of all numbers, keeps the unique problem of management of bringing of medium resource identification the whole network thereby be reduced to.
Consult shown in Figure 3ly, the user inserts the NGN network by media gateway, by soft switch calling is controlled; Be triggered to application server for intelligent call service and carry out corresponding service processing.Deposited media resource on the Media Resource Server, each media resource adopts E.164 number mark (area code will be with in the resource distribution in the Resource Server) as shown in the table respectively:
| Resource identification (E.164 number) | Media resource |
| 26540001 | The just busy voice of user |
| 26540002 | Have no right to use professional voice |
| … | … |
When on to soft switch and application server, carrying out the static configuration of media resource, operating protocol and resource place MRS to media resource are configured by existing method, medium resource identification is then used E.164 number (area code that comprises the MRS location), i.e. configuration media resource and mapping relations between the number E.164 on soft switch and application server.
When certain soft switch office point or application server need use certain class media resource (as, put certain sound) time, the query configuration table can obtain depositing the MRS of this media resource and the E.164 number of this media resource correspondence; Only need to adopt the E.164 number of normal this resource of call flow call identification then, breathe out by number analysis and by Session Initiation Protocol at last.
When soft switch or application server when E.164 there is the receiving number operation in the calling of number, the E.164 number that Media Resource Server will be received sends back soft switch or application server by the message of the SIP request resource stipulated among the RFC.
Consult shown in Figure 4, suppose that Media Resource Server is in Shenzhen, use number E.164 that voice resource " it is just busy that you dial the user who cries " is designated 0755-26540001 (area code 0755 will be with in the resource distribution in the Resource Server), the detailed process of soft switch operation " it is just busy that you dial the user who cries " media resource is as follows:
Step 10, media gateway are routed to soft switch with the calling subscriber to called subscriber's calling.
Control is called out in step 20, soft switch, finds that the called subscriber is just busy and it is called to connect, and need insert " it is just busy that you dial the user who cries " media resource to the calling subscriber.
Soft switch carries the address of the media gateway that inserts media resource in the message related to calls of initiating to Media Resource Server.
The MRS in step 60, Shenzhen finds corresponding voice resource and sends to media gateway by the media channel of setting up according to resource identification 0755-26540001.
Step 70, media gateway are play the just busy voice of user to the user.
If the called number that the calling subscriber calls out is an IN service, then soft switch routes the call to application server.Application service is carried out needing to have no right to use professional voice to user's broadcast after the corresponding service processing, then the resource distribution table according to inside finds the Media Resource Server in the Shenzhen of depositing media resource and the E.164 number-0755-26540002 of this media resource correspondence, make a call to number 0755-26540001 by Session Initiation Protocol then, its subsequent treatment and said process are similar.
From as can be known above-mentioned, media resource and soft switch and application server separate configurations, thereby can be in whole net abundant share media resource, reduce the Resource Server quantity that needs in the network widely, thereby simplify network configuration and reduce cost.
