Abstract

A method of calling on-net users in to store the IP address of ID and dynamic allocation of the user when the registers on-net to ICW server when main user A makes call to user B, he finds out B being on-net to transmit IP address of user B stored to the gate, calling B with IP call with the gate and transforms the IP address to digital alphabetic string to realize quick transmitting independently or by way of the telephone number of user B to save the cost of network operation by abandoning costly VOIP chip.

Description

A kind of method of calling online user

The invention belongs to IP (internet protocol, the Internet protocol) communications field, be specifically related to just call out method the Internet user by IP.

The telephone subscriber can dial up on the telephone by telephone wire, when the user surfs the Net by telephone wire, need take telephone line, and at this moment if phone is arranged, because common phone is the mode of monopolizing, busy line will cause phone to connect to come in so fully.For solve Internet user online and make a phone call between contradiction, meeting the tendency has produced the incoming call indicating services, notifies the Internet user by caller identification, the indication Internet user selects onlinely to answer, refusal or tone information etc.If the user selects online answering, wherein key technology is exactly the IP address that how to obtain the called subscriber, and how the IP address is transmitted in IP calls out.

The incoming call indicating services belongs to ICW (Internet Call Waiting, internet call is waited for) business, common ICW business comprises incoming call indicating services, Voice Mailbox, IP phone, be to realize call-in reporting, finish IP call establishment and conversation by special VOIP (Voice over IP) chip then by a webserver (ICW server).The VOIP chip is in the same place with the ICW server is integrated, carries out information interaction by the communication mode on the network each other.For the incoming call indicating services,, find that the callee surfs the Net when calling party makes a call, just feed back to the ICW server, when the called subscriber selected network to answer, the ICW server was passed to VOIP to called subscriber's IP address, after VOIP receives called IP address, call out to the called initiation IP of correspondence.But special on the one hand VOIP chip price costliness on the other hand, has many manufacturers that have IP gateway development ability and experience at present, and they fully can be on the prior art basis, and cost is developed the ICW business of oneself than low-cost.

For this reason, purpose of the present invention is exactly to propose a kind of method of utilizing existing equipment to come calling online user, realizes the ICW business, thereby abandons expensive VOIP chip, reduces the cost of the Internet business.

For realizing above purpose, the invention provides a kind of method to just calling out the Internet user, it is characterized in that called Internet user's IP address is transmitted by the telephone number mode, set up the IP phone path with called Internet user then.

This method further may further comprise the steps:

A) obtain called Internet user IP address;

B) send the IP address to called gateway by the telephone number mode, and initiate IP by called gateway to called Internet user and call out;

C) foundation and called Internet user's IP phone path.

Wherein, the described called Internet user IP address process of obtaining is:

IP address of dynamic assignment when a) the subscriber dialing online is logined, and online registration is in the ICW server;

B) dial Internet user's telephone number, subscriber exchange detects busy, carries out predefined Call Forwarding On Busy function and transfers the call to the ICW server, by ICW server parses Internet user's IP address, and notifying the Internet user that incoming call is arranged, the indication user makes the selection of whether answering;

C) if the Internet user has selected Internet phone-calling just stored IP address to be extracted.

Wherein, the described process that the IP address is sent to called gateway and make a call is as follows:

A) the IP address transition is become character string, and send by the telephone number mode after before character string, adding distinguishing mark;

B) be judged as by the IP address according to the distinguishing mark in the IP address character string that sends and undertaken distinguishing mark being removed after IP calls out, so make a call to the called subscriber.

Wherein, described distinguishing mark comprises in order to the distinguishing mark that is identified as the IP address with in order to be identified as distinguishing mark two parts that IP calls out.

It is one group of data of IP address that described distinguishing mark also can just transmit number in order to identification.

Wherein, described IP address is to send in the telephone number mode separately, or sends with Internet user's telephone number.

The present invention sends the method for Internet user IP address by the telephone number mode, has abandoned expensive VOIP chip, thereby has reduced the cost of the Internet business, has realized transmitting in real time fast of IP address simultaneously, has and realizes simple, fast high-efficient advantage.

Elaborate the present invention below in conjunction with drawings and Examples.

Fig. 1 is one of networking mode of realizing the calling online user method;

Fig. 2 is two of the networking mode of realizing the calling online user method.

The calling online user method is applicable to various networking modes among the present invention, and Fig. 1 shows a kind of typical networking, and (GW is Gateway) with last user B to comprise ICW server, Service Switching Point, gateway in this networking.As user A calling party B, find that the other side surfs the Net, just the IP address with user B passes to gateway, initiates IP by gateway to called subscriber B and calls out.In order to realize transmitting fast, the IP address spaces can be become numeral, send by the telephone number mode.Describe entire I P calling procedure in detail below in conjunction with networking mode shown in Figure 1.

At first, ICW user B dials up on the telephone, and when logining the authentication word (ID) of user B and the IP address of dynamic assignment is sent to the ICW server, and stores.

Dial the telephone number of Internet user B as calling party A, the SSP of called subscriber B side detects busy, just carry out predefined Call Forwarding On Busy function and transfer the call to the ICW server, the ICW server is resolved to the IP address of user B according to the ID of called subscriber B.

The ICW server is according to the IP address of the user B that resolves, initiate the incoming call indication to user B, this moment, user B will receive call-in reporting, prompting user B selects Internet phone-calling, perhaps change Voice Mailbox etc., this moment, user B was if select Internet phone-calling, and the ICW server will be passed to GW to the IP address of user B, and GW initiates IP according to this IP address to user B and calls out.

In order to set up the IP phone path rapidly, the present invention sends to called gateway with called subscriber IP address with the telephone number transfer mode, initiates IP by called gateway and calls out, and detailed process is as follows:

A) the IP address transition with the user B that is resolved to becomes character string, and sends by the telephone number mode add distinguishing mark before character string after.

The length of the IP agreement regulation IP address of using is 32 binary systems at present, and each IP address is made up of 48 bits, separates with round dot between per 8 binary systems.For ease of memory, represent with four groups three decimal number that usually the centre separates with round dot, every group of decimal numeral span is between 0～255.Present embodiment becomes 12 character to decimal strings with the IP address transition, " 10.11.111.16 " can convert " 010011111016 " to as the IP address, four groups of numerals that are about in the IP address realize that by adding " 0 " every group is fixed as three decimal numbers respectively, and with every group of interdigital round dot deletion.Add before this character string then in order to be identified as by the IP address and initiate the distinguishing mark that IP calls out, the distinguishing mark of present embodiment is divided into two parts, and one is to offer gateway in order to discern three decimal numbers that this character string is the IP address, as " 018 "; It is two for offering SSP in order to be identified as three decimal numbers of this callings for IP calling, as " 019 ".IP address after treatment just can send to SSP by the telephone number mode.

B) SSP and gateway are judged as by the IP address according to the distinguishing mark in the IP address character string that sends and are undertaken distinguishing mark being removed after IP calls out, and make a call to the called subscriber then.

The IP address character string of the Internet user B after treatment that SSP receives should be 18 decimal numbers, as " 019018010011111016 ", the distinguishing mark " 019 " of SSP before according to character string judges that this calling is that IP calls out, just " 019 " is cut out, then Remaining Number is sent to gateway by No.1 (ISDN PRI) signaling.15 decimal system called numbers " 018010011111016 " that gateway will receive are analyzed, and judge that according to distinguishing mark " 018 " this call number is the IP address, initiate IP to user B then and call out, and set up the IP phone path.

The present invention is because the IP address that will be stored in the ICW server sends to gateway in the mode of telephone number, and initiation is to Internet user's calling, and without the VOIP chip, so can finish call establishment fast on the one hand, simultaneously existing networking mode can not changed, do not need to increase to finish under the prerequisite of any equipment yet and call out indicating services (ICW business), saved cost.

It more than is elaboration that invention is used rather than to the restriction of protection range; anyly transmit IP address realize the sending a telegram here method of indicating services (ICW business) by the telephone number mode and all should drop within the protection range of the present invention, for example application of this method in networking mode as shown in Figure 2.Networking shown in Fig. 2 is existing another networking mode commonly used, and this networking comprises ICW gateway, ICW server, calling party A, called subscriber B and network access server (NAS), is connected with the Internet (IP) by public network (PSTN) between them.The difference of it and the networking shown in Fig. 1 is that the ICW server directly links to each other by relaying with gateway, between communicate by ISDN PRI, and ICW server among Fig. 1 and gateway are by the SSP transfer, and calling out in addition to insert also needs to be relayed to the ICW server by SSP.Therefore when the present invention uses in networking shown in Figure 2, at call establishment stage, original all contacting directly and handling by the SSP transfer by ICW server and gateway.Also because the omission of SSP when the IP address is sent to gateway by the telephone number mode, wherein also can be omitted in order to the distinguishing mark that is identified as the IP calling for SSP, distinguishing mark is only become by the one group of array that in order to identification number is the IP address.Also have, when the present invention transmits Internet user IP address by the telephone number mode, can only transmit the IP address as required, also IP address and Internet user's telephone number can be bundled and send.The change of these unsubstantialities is all within claim protection range of the present invention.
