technical field

The invention relates to an exchange number routing method of a telecommunication network, in particular to the function of a telephone exchange.

Background technique

It is one of the basic functions of the switch to connect the called terminal according to the calling or called number (segment) routing table data configured in advance. The disadvantage of the existing routing method is that it can only set up a relay or connect a called terminal according to the calling or called number (segment) itself. If routing is done according to a single number, the routing table data used for matching is huge , which affects system efficiency; if routing is only done according to the number segment, the end users within a segment of the number must take exactly the same route, which is not easy to realize the personalized function of the user. The triggering of some personalized intelligent network services also requires that the switch can change the calling or called number according to a certain user attribute so as to be able to trigger the intelligent network services.

Detailed ways

According to the method for changing numbers according to user attributes according to the present invention, its main steps are as follows:

The first step is to add a "special user attribute" feature to the user data of each user assigned a number on the switch. This feature is used to store: the user's flag such as whether to activate a certain service/smart service; corresponding to this flag, it needs to be changed number, such as changing the calling number, changing the called number, or changing both the calling and called numbers, etc.; the number changing rules corresponding to this mark, such as adding prefixes and suffixes to the calling/called numbers. Users can have multiple attributes of this type and specify their priority in processing.

In the second step, no matter whether the user is calling or called, when the call starts (calling or terminating), the call process on the home switch finds the user data of the user, checks the special user attributes, and according to the special user attributes Configure the conversion number.

In the third step, the call process on the home switch routes the call to the next switching office or connects to the called terminal according to the routing table configuration data and the converted number.

Further, the method of the present invention also includes software functions on the switch maintenance interface: the operator operates the software to set user attribute data and routing table data.

Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

The hardware part of the present invention is still composed of switches, and the switch hardware is not changed.

The processing steps of the software part are as follows:

According to the number conversion of special user attributes, the calling process and the called process can be implemented on the calling switch and the called switch respectively, as shown in Figure 1 and Figure 2.

According to the number conversion function of the special user attribute, at first the user data on the exchange will be expanded, as the first step of the present invention, add a "special user attribute" feature for each user who assigns a number on the exchange, and this feature is used to store : The user’s sign such as whether to open a certain service; the number corresponding to this sign needs to be changed, such as changing the calling number, changing the called number or changing both the calling and called numbers, etc.; corresponding to the number changing rule of this sign, Such as adding prefixes and suffixes to calling/called numbers. Users can have multiple attributes of this type and specify their priority in processing.

As shown in Figure 1, the implementation steps of the method of the present invention on the calling switchboard are as follows:

Step 11, when the caller goes off-hook and dials, the call starts (starting the call);

Step 12, the call process on the calling home switch finds the calling party data, checks the special user attribute of the calling user, and judges whether the number needs to be changed according to the calling user attribute according to the configuration of the special user attribute; if so, then executes step 14, Otherwise go to step 13;

Step 13, process the original process with the exchange, and then end the calling process;

Step 14, judge whether to change the calling party number; If so, then perform step 15, otherwise go to step 16;

Step 15, transform the calling number according to a predefined algorithm (number transformation method set in advance by the user);

Step 16, judge whether to change the called number; if so, then execute step 17, otherwise go to step 18;

Step 17, transform the called number according to a predefined algorithm (number transformation method set in advance by the user);

Step 18, the call process on the calling home switch routes the call to the next switching office or connects to the called terminal according to the routing table configuration data and the converted number (including the calling number and/or called number).

As shown in Figure 2, the implementation steps of the method of the present invention on the called switch are as follows:

Step 21, when the call arrives at the called switch, the called process call starts;

Step 22, the call process on the called home switch finds the called user data, checks the special user attribute of the called user, and judges whether the number needs to be changed according to the called user attribute according to the configuration of the special user attribute; if so, then execute step 24, Otherwise execute step 23;

Step 23, process the original process with the switch, and then end the called process;

Step 24, judge whether to change the calling party number; If so, then perform step 25, otherwise go to step 26;

Step 25, transform the calling number according to a predefined algorithm (number transformation method set in advance by the user);

Step 26, judge whether to change the called number; if so, then perform step 27, otherwise go to step 28;

Step 27, transform the called number according to a predefined algorithm (number transformation method set in advance by the user);

Step 28, the call process on the called home switch routes the call to the next exchange or connects to the called terminal according to the routing table configuration data and the converted number (including the calling number and/or called number).

For example, use the fixed exchange of the present invention to predefine a user attribute: "fixed phone color ring" attribute, the attribute value code is 1, and a user number conversion rule R1 is predefined: the conversion rule category is " called rule " (valid condition is : The user is called, and the exchange has not done any other processing on the called number before using the rules), the number of the calling user is not changed, and the prefix 988 is added to the called number. Assuming that there is a user number 52871273 on the exchange, the attribute is set to "1" (fixed phone ring tone attribute) for this user now, and the number conversion rule is set to "R1". In this way, when a calling user dials the number 52871273, the call arrives at the exchange, and the process of processing the call checks the attribute of the user number 52871273, and finds that the user has set the attribute "1", then searches for the user's number conversion rule R1, according to R1 , Change the called number to "98852871273", and then connect to the new called number 98852871273, realizing the purpose of routing according to user attributes.

Combining the above example with the "Number Analysis" function on the switch, you can realize the "fixed phone color ring" in the intelligent network mode: define the number analysis on the switch: remove the prefix 987 to continue the called number starting with the prefix 987. Therefore, after the above-mentioned call starting with the called number 988 is received by the CRBT center, the CRBT center modifies the prefix 988 to 987, and then the call is connected back to the switch. The switch analyzes the number in advance and continues the number 52871273. Analysis and processing, at this time the R1 rule no longer works, the phone terminal 52871273 rings, and the CRBT center plays the CRBT tone to the calling user at the same time.

In addition, the method of the present invention also includes software functions on the switch maintenance interface: the operator operates the software to set user attribute data and routing table data.

In this embodiment, the calling switch and the called switch are respectively taken as examples to describe the implementation of number conversion according to special user attributes in the present invention. The present invention overcomes the shortcoming that the existing exchange cannot route and connect calls according to individual user requirements, solves the problem of personalized routing calls for end users of the exchange, and can also be used to trigger intelligent network services according to user attributes.

Of course, the present invention can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the present invention without departing from the spirit and essence of the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
