Can be according to the relation between the name in the parameter change IP address of any number and the DDNS server 18.One of them this parameter can be the time of every day.For example, line directory company can send calling to transmission order of first website and time in the afternoon with first physical address to second website with second physical address in the time in the morning.

The Intelligent treatment of domain name is particularly useful in the digital telephone that allows audio frequency (video sometimes) to transmit by the internet connection.Digital telephone by the internet is connected between two or more IP addresses and transmits audio/video data packets.Digital telephone connects and can be used for many business environments, for example customer need and the line directory business of representing talk.SCP10 can make digital telephone be connected to some available one of them in the business agent of diverse location.Digital telephone connects can be based on time of every day, current loading or such as other parameter of user ISP or LEC local exchange carrier.This allows representative to be positioned at different positions, comprises for example his or her family, and simultaneously, SCP10 makes digital telephone be connected to correct position.

Another used parameter is request user's address in the process IP address.The user is also linked according to this address the homepage or the digital telephone set of appointment in the professional search request user's of IN address.For example, Pizza chain store may have the number in the whole nation.In case called out, dynamic data base according to the ANI that calls out (number identification automatically) determine the IP address, then with this address with set up digital telephone near user's position and be connected.

Can be used for determining that from dynamic name server 18 other parameter of IP address comprises time, weekly day, user's telephone number and other the user profile information such as age, sex, income or the like.A plurality of parameters can be used for determining the IP address relevant with DDNS.

It should be noted that in the internet typical case be used to search the non-DDNS server of the type of domain name can cache from the address of DDNS server 18, this can change the function of the dynamic nature of DDNS server 18.For preventing that by other name server cache DDNS server 18 must transmit the lasting parameter (" time to live " or " TTL ") that equals " 0 " together with the IP address.

In operation, PSTN regards SCP10 as SS7/C7 by TCAP and connects the typical IN (intelligent network) that can carry out SCP on 20.In addition, SCP10 can communicate by letter with miscellaneous equipment in connection 22 by SLEE12.Therefore, if the PSTN device request from the business information of SCP10, is just recovered it by SLEE12 from database manager 14 as usual.

Other equipment can obtain from DDNS server 18 information of (with database manager 14) by connecting 22 from SCP.In an illustrated embodiment, SLEE12 communicates with TCAP.If want to use other protocol communication, just translation software can be added so that allow and the communicating by letter of other agreement.For example, by using programmable TACP SLEE12, ISUP can be used for allowing and the communicating by letter of ISUP equipment to the transducer of TACP.This transducer joins the TACP head input message and remove the TACP head from output message.This allows to use existing message interface able to programme, of for example finding in DSC INFUSION product in SCP10.Perhaps, be similar to the SLEE that discusses in conjunction with above referenced United States Patent (USP) 60/086,971, SLEE12 can communicate with many different agreements.

Fig. 2 explanation is based on the gateway equipment 30 of the SCP10 structure of Fig. 1 b and 1c.In H.323 netting, gateway has four major functions.The first, gateway is carried out and is admitted control, that is, it determines whether equipment can begin or terminated call.The second, the bandwidth that gateway carries out defining in RAS (register, admit and state) standard is controlled.The 3rd, gateway carries out the address and translates into IP or IPX address (also defining) from the LAN another name of terminal and gateway the RAS standard.The 4th, gateway (being called the gateway zone) in its zone monitors all terminals, gateway and MCU (multipoint control unit).

Gateway 30 shown in Figure 2 is similar to the SCP10 shown in Fig. 1 b and the 1c, but it has increased an additional interface, UDF (user definition function) MSG interface 32.UDF MSG is user definition SIB (a separate traffic basic composition piece), and in this situation, its handles H.225 and the H.245 control messages of agreement H.323 descend defined.UDF MSG interface is linked ULS (general positioning service) 34 and is linked one or more gateways 40 (will describe in more detail in conjunction with Fig. 3) by RAS channel 38 by 225/RAS channel 36.

ULS is that the software operated of network provider is so that use the suitable parameters login user.This software is directly communicated by letter with the internet positioning service of server.Gateway 30 when the user first during accesses network on internet/data network 6 registration parameter I P address and to the IP address (, may distribute different IP addresses) of each number dialing telephone call registration dynamic assignment to the user because for each number dialing telephone call.

In operation, gateway, also have H.323 substandard its need and the business selected can also be used for utilizing the information of Fig. 1 b and the described dynamic-dns 18 of 1c to set up between the digital telephone, between pstn telephone and the digital telephone and the connection between the pstn telephone.Though it should be noted that the gateway 30 of incorporating Web server 16 and JAVA server 17 presentation graphs 2 into, equally only the JAVA server 17 represented with the SCP of Fig. 1 b of configuration.
