Abstract
The present invention discloses a method for unifiedly managing intra-domain number resources in a voice network, which comprises the following steps: setting a default port number for a port of each gateway; specifying a subscriber number on a server for each port of each gateway; configuring a gateway port and a number mapping table on the server; preserving the corresponding relation of the gateway ID+ port number and the subscriber number. The server converts a called number into an IP of the called gateway and feeds back the IP to the calling gateway, and the calling gateway directly sets up calls with the called gateway; otherwise, the server finds the IP of the called gateway by the called number, a call request is routed to the called gateway, and a route call is set up.
Description
Technical field
The present invention relates to the management method of number resource in a kind of speech network, the method for number resource in the unified management territory in particularly a kind of speech network.
Background technology
Along with the development of IP technology, IP phone/facsimile art becomes a big focus.
Traditional VOIP (based on the voice of IP technology) network generally adopts H.323 agreement, and functional entity has gatekeeper, gateway (GW), terminal (Terminal).Among NGN (next generation network), the SoftSwitch (soft switch) general adopt SIP, H.248, agreement such as MGCP; Functional entity has equipment such as acting server, Redirect Server, user terminal, gateway in the SIP network.H.248, the major function entity has Media Gateway Controller (MGC), media gateway (MG) in the MGCP network.
No matter being which kind of network, no matter using which kind of (or which is planted) agreement, all is Client-Server (client one server) structure.The Client that each Server and it are controlled forms a territory.Server is controlling the Client in the territory, and services such as Client address resolution, Bandwidth Management are provided.It is pointed out that the territory can with the general structure-irrelevant of opening up of network layer, a plurality of network segments that can be cross-domain connect by router or miscellaneous equipment such as a territory.
The critical function of Server is the address resolution in carrying out the territory, and it converts the called number in caller gateway or the terminal call request message to called call signaling address.This requires Server to go up must to dispose all number informations in the territory that it administers; Having a plurality of ports on the gateway can initiate and receipt of call, when a call setup message arrives gateway, it must determine which port this calling will be based upon on by called number, so also must dispose the number information of its each port on the gateway.
That is to say that number information must dispose respectively, and is consistent on Server and gateway.
For keeping the consistent of number information on Server and the gateway, need on gateway, dispose the number of its each port, simultaneously the number information that h.323-configured gateway can be supported with it on Server.Equally, when number information be modified, when deleting, the keeper will implement corresponding operating respectively on Server and gateway.
Because number information will be retained on gateway and the Server simultaneously, be the consistency of guarantee information, just need synchronously.Carry out when synchronous when mode by hand, this work may be very loaded down with trivial details, particularly having under the situation of up to a hundred gateways.
For keeping the consistency of number information on Server and the gateway, another way is the number of its support of configuration on gateway, reports Server by gateway again.
Use no doubt can be addressed this problem by the way that gateway reports voluntarily, but in a territory, Server has only one, and gateway quantity is very big, and the user still needs to be connected on each gateway and is configured.Moreover being initiated by gateway synchronously of this information, Server is passive receiving number information, and is inconsistent with the status of the management of Server in the territory, control.Can learn that from above-mentioned prior art no matter number information is to be initiated or initiated by gateway by Server synchronously, perhaps manual carrying out all is a very loaded down with trivial details thing.
Summary of the invention

● the caller gateway to called gateway make a call (Direct Call) or via Server to called gateway make a call (Routed Call), which kind of mode no matter is dealt in the call setup request message of called gateway and should comprises the cornet (port numbers 2) of called gateway and the Subscriber Number (trombone 5550001) of caller;
● called gateway navigates to called port by cornet (2), sets up calling, and if called caller number display arranged, correct display of calling number (5550001) on called phone.
3.3 if the calling and called gateway all in different territories, uses Direct Call mode: (port one of GW1 calls out 7770003)
● calling subscriber's (port one of GW1) makes a call to Subscriber Number (7770003);
● the caller gateway uses trombone (7770003) to the Server request of making a call, and calling number is cornet (port numbers 1);
● Server is by number analysis, and learning called is not the gateway territory in, need be by another Server processing; Server is index search gateway port and number mapping table with caller gateway ID (GW1)+cornet (port numbers 1), obtains the Subscriber Number (5550001) of caller;
● caller Server sends to called Server with call request, and called number wherein is Subscriber Number (trombone 7770003), and calling party number ' s convert is a Subscriber Number 5550001;
● called Server is by number analysis, and learning called is a gateway in the territory, is index search gateway port and number mapping table with trombone (7770003), obtains called gateway ID (GW3) and cornet (port numbers 3); Because be Direct Call, calling and called Server only is responsible for the translation of number to IP, called Server is with the IP of called gateway GW3, with the called number (port numbers 3) after the conversion, feed back to caller Server, caller Server is sending to these information caller gateway (calling number 5550001, called number 3, called IP);
● the caller gateway is directly to called gateway make a call (calling number 5550001, called number 3, the IP of called gateway GW3);
● called gateway (GW3) navigates to called port by cornet (3), sets up calling, and if called caller number display arranged, correct display of calling number (5550001) on called phone.
3.4 if the calling and called gateway all in different territories, uses Routed Call mode:
● calling subscriber's (port one of GW1) makes a call to Subscriber Number (7770003);
● the caller gateway uses trombone (7770003) to the Server request of making a call, and calling number is cornet (port numbers 1);
● Server is by number analysis, and learning called is not the gateway territory in, need be by another Server processing; Server is index search gateway port and number mapping table with caller gateway ID (GW1)+cornet (port numbers 1), obtains the Subscriber Number (5550001) of caller;
● caller Server sends to called Server with call request, and called number wherein is Subscriber Number (trombone 7770003), and calling party number ' s convert is a Subscriber Number 5550001;
● called Server is by number analysis, and learning called is a gateway in the territory, is index search gateway port and number mapping table with trombone (7770003), obtains called gateway ID (GW3) and cornet (port numbers 3); Because be Routed Call, calling and called Server also is responsible for call establishment except being responsible for the translation of number to IP.Therefore call request is sent to called gateway (calling number 5550001, called number 3, called IP);
● called gateway navigates to called port by cornet (3), sets up calling, and if called caller number display arranged, correct display of calling number (5550001) on called phone.
Need to prove, when describing inter-domain call, suppose that calling and called all use the mode of DirectCall when controlling call, two kinds of situations (caller ServerDirect Call, called ServerRouted Call in addition, caller ServerRouted Call, called ServerDirect Call) flow process just do not described one by one here.
Use the technique effect of this programme to be:
1) on Server for each port of each gateway is provided with Subscriber Number, really realized the management of Server in the VOIP network and the core status of control;
2) do not preserve the Subscriber Number of each port on the gateway, reduced the workload of data configuration, reduce the complexity of data sync.
