Abstract

The present invention discloses a method and system used for the border gateway deals with the medium gateway control protocol and the user register, wherein, the method includes an IAD through parsing, namely, the domain of the Integrated Access Device and a MGCP, namely, the local endpoint name of the medium gateway control protocol terminal; looking up from the IAD information which has registered and kept, the IAD information includes an IAD domain, the local endpoint name of the MGCP terminal and a register status marking; when finding out the IAD information which is same as the parsed IAD domain, local endpoint name of the MGCP terminal in the IAD information is compared with the local endpoint name of the parsed MGCP terminal; if the two are same, the register status marking is marked as failure, and sending a registration request to the SS, namely, the Soft Switch avoiding the trouble that the other register success terminals are incapable of sending the calling because the last register message is unsuccessful.

Description

The method and system of boundary gateway to process media gateway protocol user register

Technical field

The present invention relates to communication technical field, relate in particular to a kind of method and system of boundary gateway to process media gateway protocol user register.

Background technology

At present, have BGW (Board Gateway, borde gateway) SS (Softswitch) communication construction comprises: SS, BGW, IAD (Integrated Access Device, integrated access equipment) and MGCP (Media Gateway Control Protoco1, MGCP) terminal.

Every IAD needed to register to the soft switch control appliance before access soft handoff network, also can preserve the log-on message of integrated access equipment simultaneously on the borde gateway.Every IAD has a domain name and identifies, and every MGCP terminal of its administration also has local side roll-call (LocalEndpointName) to be distinguished.

At present, in the existing procedure of Softswitch registration, IAD can be according to the quantity of the MGCP terminal of its administration by borde gateway for IAD, by sending the register requirement of respective numbers successively, by BGW to the SS request registration.

Such as, IAD at first sends article one register requirement, and the end points that comprises is called aaln/1@domain.Suppose to succeed in registration, the MGCP terminal aaln/1 under the IAD that on the SS can be domain to domain name is changed to the state of succeeding in registration.On BGW, can preserve IAD domain name domain, put login state simultaneously and be masked as and be.

Then, IAD sends second successively ... n bar register requirement, and the end points that n bar register requirement comprises is called aaln/n@domain.If the register requirement of front is success all, have only and do not succeed in registration for the n time.MGCP terminal aaln/n under the IAD that on the SS can be domian to domain name is changed to and registers not success status.On BGW, to handle according to heavy login mechanism, the login state sign of the IAD that so last domain name is domain just is not.

As can be seen from the above, because in registration process, just the last item register requirement that BGW is concerned about all the time is if the last item register requirement has been failed the problem that will cause other MGCP terminal that succeeds in registration also can't make a call.

Summary of the invention

The invention provides a kind of borde gateway and handle MGCP user's process registration and system, in order to solve the problem that causes other terminal that succeeds in registration also can't make a call because of the failure of the last item registration message.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides a kind of borde gateway and handle MGCP user process registration, comprising:

Steps A: BGW is that the register requirement that integrated access equipment sends is resolved according to IAD, obtains the domain name of IAD and local side that the MGCP terminal is the MGCP terminal and calls the roll;

Step B: described BGW searches in registering the IAD information of preservation, when finding the IAD information identical with the described IAD domain name that parses, the local side roll-call of MGCP in the described IAD information that finds is compared with the local side roll-call of the described MGCP terminal that parses: if identical, the login state of then putting in the IAD information is masked as not, and be the Softswitch request registration, otherwise directly to the SS request registration to SS;

Step C: described SS accepts register requirement, carries out location registration process, and sends the registration response to described BGW;

Step D:BGW is provided with the login state sign of described MGCP terminal according to the registration response that receives, and transmits the registration response and give described IAD.

Further, described step B also comprises: when described BGW does not find the IAD information identical with the described IAD domain name that parses, then add new IAD information, and put login state and be not masked as not, simultaneously to the SS request registration.

The IAD information of described new interpolation comprises: the local side of described IAD domain name that parses and MGCP terminal is called the roll.

Further, described step C specifically comprises:

Step C1:SS accepts the register requirement of BGW, and the local side of the MGCP terminal in the register requirement called the roll judge: represent the corresponding field sign of all MGCP terminals under one's name if the local endpoint of MGCP terminal is by name, then all the MGCP terminals under the IAD of corresponding domain name all are changed to the state of succeeding in registration; If local endpoint is called concrete MGCP terminal, then the corresponding MGCP terminal under the IAD of corresponding domain name is changed to the state of succeeding in registration;

Step C2:SS sends the registration response to BGW.

Further, described step D specifically comprises:

Step D1:BGW receives the registration response, judges whether SS succeeds in registration: if registration failure is directly transmitted the registration response and given IAD; If succeed in registration, the local side of then replacing in the local endpoint described registration reply message by name of MGCP end points of current preservation is called the roll, and puts login state simultaneously and is masked as and is;

Step D2: transmit the registration response and give IAD.

The present invention also provides a kind of borde gateway to handle the system of MGCP user registration, and comprising: SS is that Softswitch, BGW are that borde gateway, IAD are that integrated access equipment and MGCP terminal are the MGCP terminal, wherein,

Described IAD is used for sending register requirement to BGW;

Described BGW is used for parsing from described register requirement the local side roll-call of domain name and the MGCP terminal of described IAD; When described BGW finds the IAD information identical with the described IAD domain name that parses, the local side roll-call of MGCP in the described IAD information that finds is compared with the local side roll-call of the described MGCP terminal that parses: if identical, then putting login state is masked as not, and to the SS request registration, otherwise directly to the SS request registration;

Described SS is used to receive the register requirement that described BGW sends, and carries out location registration process, and sends the registration response to described BGW.

Further, described BGW also is used for: according to receive the registration response from SS, judge whether SS succeeds in registration: if registration failure keeps the login state sign constant, and transmit the registration response and give IAD; If succeed in registration, then replace in the request of local endpoint described registration response by name of MGCP end points of current preservation corresponding local side and call the roll, putting simultaneously that login state is masked as is to transmit the registration response then and give IAD.

Further, when described BGW does not find the IAD information identical with the described IAD domain name that parses, described BGW also is used for the local side of described IAD domain name that parses and MGCP terminal called the roll and adds new IAD information to, and puts login state and be masked as not, simultaneously to the SS request registration.

In sum, the embodiment of the invention provides a kind of method and system of boundary gateway to process media gateway protocol user register.In the present embodiment, have only when domain name is called the roll simultaneously identical situation with local side under just by heavy location registration process.Like this, when IAD carries out register requirement, just can not be used as heavy location registration process to the later registration message of article one, thereby avoid the problem that causes other terminal that succeeds in registration also can't make a call because of the failure of the last item registration message.

Embodiment

Below in conjunction with accompanying drawing the described method and system of the embodiment of the invention are described in detail.

At first, the described method of the embodiment of the invention is described in detail.

As shown in Figure 1, Fig. 1 is the flow chart that the present embodiment borde gateway is handled MGCP user's registration, specifically can may further comprise the steps:

Step 101:IAD sends registration message to BGW, the end points name LocalEndpointName@DomainName that comprises in the described registration message, and wherein, LocalEndpointName is that the local side of MGCP terminal is called the roll, DomainName is the domain name of IAD.

Step 102:BGW receives the registration message that IAD sends, and described registration message is resolved, and parses LocalEndpointName and DomainName and carries out following processing afterwards:

102.1:BGW search in the IAD information of having registered, described IAD information comprises: LocalEndpointName, DomainName and login state sign;

If do not find the identical IAD of domain name, then add new IAD information, and the LocalEndpointName and the DomainName that parse above put into wherein, put login state simultaneously and be masked as unregistered successfully sign, such as, can put login state sign bRegistered is not, and transmits described registration message and give SS;

102.2:BGW in the IAD information of having registered, search,, carry out following processing if find the IAD that has domain name identical:

102.2.1: whether the LocalEndpointName that preserves in the IAD information that relatively finds is identical with the LocalEndpointName that described registration message parses, if it is inequality, then directly transmit described registration message and give SS, the IAD information of original preservation is not made any modification;

102.2.2: if the LocalEndpointName that preserves in the IAD information that relatively finds is identical with the LocalEndpointName that described registration message parses, then revise login state sign bRegistered for denying, no matter what original login state is, transmits described registration message then and give SS;

Step 103:SS receives described registration message, when succeeding in registration, if LocalEndpointName is ^*, then all the MGCP terminals under the IAD of corresponding domain name all are changed to the state of succeeding in registration; If LocalEndpointName is concrete MGCP terminal, then the corresponding MGCP terminal under the IAD of corresponding domain name is changed to the state of succeeding in registration;

When the SS registration failure, if LocalEndpointName is ^*, then all the MGCP terminals under the IAD of corresponding domain name all are changed to unregistered success status; If LocalEndpointName is concrete MGCP terminal, then the corresponding MGCP terminal under the IAD of corresponding domain name is changed to unregistered success status;

SS sends registration reply message to BGW then;

Step 104:BGW according to registration reply message being resolved the content that obtains, judges whether to succeed in registration after receiving the registration response:

104.1 if not success of registration is directly transmitted the registration response and is given IAD;

If 104.2 succeed in registration, the LocalEndpointName that then replaces current preservation is LocalEndpointName corresponding in the described registration message, puts login state sign bRegistered simultaneously for being; Then the registration response is transmitted to IAD.

Next, for example the described method of the embodiment of the invention is further specified.

In order to narrate conveniently, at first for example the structure of the soft exchanging communication network that has borde gateway is carried out brief description, as shown in Figure 2, Fig. 2 is the soft switch communication construction figure that has borde gateway, specifically comprise: soft switch SS101, borde gateway BGW102, borde gateway BGW103, integrated access equipment IAD104, integrated access equipment IAD105, integrated access equipment IAD106, MGCP terminal 107, MGCP terminal 108, MGCP terminal 109.Wherein, IAD104 links to each other with SS101 by BGW102; IAD106 links to each other with SS101 by BGW103; MGCP terminal 107, MGCP terminal 108 and MGCP terminal 109 insert SS101 through IAD105 and BGW102.

Every integrated access equipment has a domain name and identifies, and for example, the domain name of IAD105 is domain105.Every MGCP terminal also has local side roll-call (LocalEndpointName) to be distinguished, and for example, the local endpoint name of MGCP terminal 107,108,109 is respectively aaln/107, aaln/108, aaln/109.Also be configured the domain name (DomainName) of integrated access equipment on the control appliance of soft switch simultaneously, as domain105, and the roll-call of the local side of MGCP terminal, as aaln/107, aaln/108, aaln/109.

As shown in Figure 3, Fig. 3 is the schematic flow sheet that the described borde gateway of the embodiment of the invention (BGW) is handled MGCP user's registration, and this sentences SS102, BGW1 and IAD2 is an example, and described flow process specifically can may further comprise the steps:

At first, terminal aaln/107 registration is specially:

Step 301:IAD105 sends article one log-on message, and the end points that comprises in described article one registration message is called aaln/107@domain105.

Step 302:BGW102 receives after the described registration message, find that domain name domain105 is registration for the first time, handle, preserve DomainName:domain105 by flow process 102.1, LocalEndpointName:aaln/107, login state sign bRegistered: not.At this moment, IAD information is＜domain105 that aaln/107 not 〉, is transmitted to SS101 to described registration message then.

Step 303: if succeed in registration, SS101 puts MGCP terminal aaln/107 and is the state of succeeding in registration, and sends successfully registration response to BGW102.

After step 304:BGW receives successfully registration response, by 104.2 flow processing, replace local endpoint aaln/107 (remaining unchanged) by name here, modification login state bRegistered is masked as and is, at this moment IAD information is＜domain105, aaln/107 is 〉, last BGW is transmitted to IAD105 to the registration response.

Then, terminal aaln/108 registration is specially:

Step 305:105 (IAD) sends the second log-on message, and the end points that comprises in the described second registration message is called aaln/108@domain105.

Step 306:BGW102 receives after this message, finds that domain name domain105 is registered, and local side calls the roll and do not match, and then handles according to the 102.2.1 register flow path.Keep original IAD information constant＜domain105, aaln/107 is 〉, transmit the described registration message that send then and give SS101.

Step 307:SS101 receives described registration message, if succeed in registration, then SS101 puts MGCP terminal aaln/108 and is the state of succeeding in registration, and sends successfully registration response to BGW102.

After step 308:BGW102 receives successfully registration response, by 104.2 flow processing, replace local endpoint aaln/108 by name, it is (remaining unchanged here) that modification login state bRegistered is masked as, at this moment IAD information is＜domain105, aaln/108 is 〉, last BGW102 is transmitted to IAD105 to the registration response.

At last, terminal aaln/109 registration is specially:

Step 309:IAD105 sends the 3rd registration message, and the end points that comprises in described the 3rd registration message is called aaln/109@domain105.

Step 310:BGW102 receives after this message, finds that domain name domain105 is registered, and local side calls the roll and do not match, and then handles according to the 102.2.1 register flow path.Keep original IAD information constant＜domain105, aaln/108 is 〉, send register requirement to SS101.

Step 311:SS101 receives described registration message.If registration failure, then to put MGCP terminal aaln/109 be unregistered success status to SS101, and send failed registration and respond to BGW102.

After step 312:BGW102 receives failed registration response, handle, directly the failed registration response sent to IAD105 according to 304.1 register flow paths, keep original IAD information constant＜domain105, aaln/108 is 〉.

Like this, even as can be seen under the situation of endpoint registration failure in the end, other terminals of successfully registering still can normally make a call.

At last, in conjunction with the accompanying drawings the described system of the embodiment of the invention is described in detail.

As shown in Figure 4, the structure of the described system of the embodiment of the invention is identical with framework shown in Figure 2, specifically comprises: SS is that Softswitch, BGW are that borde gateway, IAD are that integrated access equipment and MGCP are the MGCP terminal.

Each part to the described system of the embodiment of the invention is elaborated below.

Described MGCP terminal is subordinated to IAD, is subjected to the administration of IAD.

Described IAD is used for sending register requirement to BGW, and each IAD can administer a plurality of MGCP terminals simultaneously.

Described BGW is used for parsing from described register requirement the local side roll-call of domain name and the MGCP terminal of described IAD; Then the local side that parses the domain name of described IAD and MGCP terminal in the described register requirement is called the roll with BGW in compare in the IAD information of having stored and search, can have two kinds of situations this moment: first kind of situation, when described BGW finds the IAD information identical with the described IAD domain name that parses, the local side roll-call of MGCP in the described IAD information that finds is compared with the local side roll-call of the described MGCP terminal that parses: identical with the local endpoint name of the described MGCP terminal that parses if the local side of the MGCP in the described IAD information that finds is called the roll, then put login state and be masked as unregistered success, and to the SS request registration; If it is different with the local side roll-call of the described MGCP terminal that parses that the local side of the MGCP in the described IAD information that finds is called the roll, then described BGW is directly to the SS request registration.Second kind of situation, when described BGW does not find the IAD information identical with the described IAD domain name that parses, described BGW also is used for adding the local side roll-call of described IAD domain name that parses and MGCP terminal to new IAD information, and put login state and be masked as unregistered success, simultaneously to the SS request registration.

Described SS is used to connect described SS and accepts register requirement, carries out location registration process, and sends the registration response to described BGW.

Described BGW judges according to receive the registration response from SS whether SS succeeds in registration: if registration failure keeps the login state sign constant, and transmit the registration response and give IAD; If succeed in registration, then replace in the request of local endpoint described registration response by name of MGCP end points of current preservation corresponding local side and call the roll, put login state simultaneously and be masked as and succeed in registration, transmit the registration response then and give IAD.

For the concrete processing procedure of each part of the described system of the embodiment of the invention,, just repeat no more owing to be described in detail in the method in front herein.

In sum, the embodiment of the invention provides a kind of method and system of boundary gateway to process media gateway protocol user register.In the present embodiment, have only when domain name is called the roll simultaneously identical situation with local side under just by heavy location registration process.Like this, when IAD registers continuously to a plurality of MGCP terminals of its administration, just can not be used as heavy location registration process to the later registration message of article one.Thereby avoided the problem that causes other terminal that succeeds in registration also can't make a call because of the last item registration message failure.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
