Description

A method of realizing wide-area business group based on program-controlled exchange

technical field

The invention relates to a method for realizing a wide-area business group, in particular to a method for realizing a wide-area business group across offices on a program-controlled exchange.

Background technique

In the prior art, the business group users (that is, the Centrex service) on the program-controlled exchange are all in one exchange office, but now the large customer groups generally exist across regions and offices, and there are branches located in other cities and regions. Therefore, it is necessary to create a business group in the switching office to which each branch belongs, and other departments in the same switching office within the group need to dial the local number. With the development of the telecommunications industry, large customer groups hope that operators can form a business group with their users distributed in different cities and regions, and only need to dial the small number in the group within the group. This is the wide-area business group service.

At present, the method of realizing wide-area business group services is generally based on the intelligent network platform, requiring each switching office to be the Service Switching Point (SSP) of the intelligent network. Therefore, the equipment in the prior art requires high cost and complicated technical settings.

Contents of the invention

The purpose of the present invention is to provide a method based on a program-controlled switchboard to realize a wide-area business group, which solves the problem that large customer groups in different cities and regions distributed on different switches realize internal small number dialing, and It can be realized based on the existing program-controlled switch without the support of the intelligent network, thereby saving costs for operators. This method has the characteristics of flexibility, low cost, and does not modify the original communication network structure and the original end office switch.

Technical scheme of the present invention is as follows:

A method for implementing a wide-area business group based on a program-controlled switch, the implementation steps are as follows:

a) Configure the address of the authentication server: if the authentication server is in the local exchange, select the sign that the local office is a remote authentication server in the configuration of the local exchange; if the authentication server is not in the local exchange, then in the local exchange Select the sign of remote authentication in the office configuration, and input the address of the remote authentication server, and address according to the method provided by No. 7 signaling;

b) configuring on the authentication server the corresponding relationship between the large number and the small number in the group of the wide area business group;

c) Add the local office users in the wide area business group to the local office business group;

D) in the wide area business group, the business group number analyzer of the user number analysis selector of the local office analyzes the small numbers according to the classification of the local office calls in the Centrex business group, and selects the flag position of the wide area Centrex call; never has When other switches with the WAN business group function make outgoing calls within the WAN business group, they will be connected to the exchange with the WAN business group function by adding an access code before the called number, and the In the local network analyzer of the functional switching office, the access code is analyzed according to the category of the local office call in the Centrex business group, and the flag bit of the wide area business group call is selected and the flag bit of the wide area business group call is removed;

e) After determining that it is a wide-area business group call according to the result of the number analysis, find the called large number in the authentication server according to the calling large number and the called small number, and then add the outgoing group prefix before the called large number , and re-analyze the called number with prefix added, and select the route according to the analysis result.

Said method, wherein the method provided by No. 7 signaling in said step a) includes a global name method or a destination signaling point method.

The present invention provides a method for implementing a wide-area business group based on a program-controlled exchange. By modifying the regional characteristics of authentication on the existing program-controlled exchange, the original communication network structure and the original end-office exchange are not modified. On the basis of the Internet, it does not need the support of the intelligent network platform, and realizes the internal small number dialing of the large customer groups distributed in different cities and regions. The data of the wide-area business group is centrally configured and maintained, and the management is convenient; Other exchanges access the authentication server through No. 7 signaling, which greatly saves relay resources; users in wide-area business groups only need to dial the extension number, which is convenient to use. The invention is suitable for use across local networks.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 2, the method for realizing the wide-area business group based on the cross-office of the program-controlled exchange of the present invention, its implementation steps are as follows:

a) Set the address of an authentication server, if the authentication server is in the exchange, then select the "this exchange is a remote authentication server" sign in the configuration of the exchange; if the authentication server is not in the exchange, It is necessary to select the "Remote Authentication" flag in the configuration of this exchange, and enter the address of the remote authentication server. It can be addressed according to the GT (Global Name) mode or DPC (Destination Signaling Point) mode of No. 7 signaling .

b) Configure the corresponding relationship between large numbers and small numbers in the wide area business group on the authentication server.

c) adding the users of the exchange in the wide area business group to the business group of the exchange.

D) in the business group number analyzer of this switching office user number analysis selector in the said wide area business group, analyze the small number according to the category of "this switching office call in the Centrex business group", select the flag "is wide area Centrex call". Calls within the WAN business group that are made from other switches that do not have the function of the WAN business group will be transferred to the exchange with the function of the WAN business group by adding an access code before the called number. In the local network analyzer of the switching office with the wide area business group function, the access code is analyzed according to the category of "the call of the switching office in the Centrex business group", and the flags "is a wide area Centrex call" and "wide area Centrex call" are selected. Call Remove Access Code".

e) After determining that it is a wide-area Centrex call according to the number analysis result, the authentication server finds the called large number according to the corresponding relationship between the calling large number and the called small number, and then adds the outgoing group word before the called large number prefix, and re-analyze the number of the called large number with the prefix added, and select the route according to the analysis result.

As shown in Figure 1, it is an example of implementing a wide-area business group based on a program-controlled switch across offices. Among them, some users of five switching offices A, B, C, D, and E need to form a wide area business group, such as users of a certain group company. Among them, A, B, C, and D exchanges have the function of wide-area business group, and are of the same type of exchange, and E exchange is another type of exchange, which does not have the function of wide-area business group. Bureau. For example, for a telephone number 2568080 in the wide area business group of exchange A, its corresponding small number on the authentication server is 2080; for a telephone number in the wide area business group of exchange B 2353000, the corresponding small number on the authentication server is 2000; a certain telephone number in the wide area business group of the C exchange is 4567030, and its corresponding small number on the authentication server is 2030; A certain telephone number in the wide area business group of the D exchange is 2386045, and its corresponding small number on the authentication server is 2045; a certain telephone number in the wide area business group of the E exchange is 6453028 , its corresponding small number on the authentication server is 2028; the above-mentioned telephone set participates in forming a wide-area business group.

Since the authentication server is in the A switching office, for the A switching office, the flag "this switching office is the authentication server" needs to be selected. And B switching office, C switching office, D switching office all have wide-area business group function, can access described authentication server through No. In A switching office, B switching office, C switching office, and in the business group number analyzer of the respective local switching office user number analysis selectors in the wide-area business group of D switching office, the small numbers are processed according to the "Centrex business group internal exchange" In the category analysis of "office call", select the flag "is a wide area Centrex call". Since the E exchange does not have the wide-area business group function, the wide-area group users on the E exchange need to pass the access code, for example, 555, to tandem to the C exchange. In the local network analyzer of the C switching office with the wide area business group function, the access code is analyzed according to the category of "this switching office call in the Centrex business group", and the flags "is a wide area Centrex call" and "wide area Centrex call" are selected. Centrex call to remove access code".

Consider first the case where no access code is required. The business process is represented by the No. 1 process line. When the user 2353000 (minor number 2000) of exchange B dials the minor number 2045, the system determines "it is a wide-area Centrex call" according to the number analysis result, and accesses the authentication server of exchange A through the No. 7 signaling mode. The authentication server obtains the calling number (large number) and the called number (small number) of the wide area business group for this call according to the No. 7 signaling message from the B switching office, thereby being able to determine the number of the calling user. The corresponding wide area business group group number, and then find the large number 2386045 corresponding to the called small number 2045 in this group, and return the result to the calling office B through the No. After the large number 2386045, add the outgoing group prefix before the called large number, then re-analyze the number according to the normal call flow, and select a route to connect according to the analysis result.

Next, consider the situation of dialing with an access code. The business process is represented by the No. 2 process line. When E exchange user 6453028 (small number 2028) calls D exchange user 2386045, he needs to dial the access code + small number, that is, 5552045. After the call arrives at Switch C, Switch C determines according to the result of number analysis that it is "a wide-area Centrex call without the access code" and "it is a wide-area Centrex call". Access the authentication server of the A exchange. The authentication server obtains the calling number (large number) and the called number (small number) of the wide area business group for this call according to the No. 7 signaling message from the C switching office, thereby being able to determine the number of the calling user. The corresponding wide area business group group number, and then find the large number 2386045 corresponding to the called small number 2045 in this group, and return the result to the C exchange through the No. 7 signaling message, and the C exchange gets the large number corresponding to 2045 After the number 2386045, add an outgoing group prefix before the called large number, then re-analyze the number according to the normal call flow, and select a route to connect according to the analysis result.

It should be understood that the description of the above specific embodiments of the present invention is too specific and cannot thereby limit the scope of patent protection of the present invention, and the scope of patent protection of the present invention should be determined by the appended claims.
