Detailed ways

See Figure 1: The network service system consists of local switches, edge trunk gateways, integrated access devices (IAD), access media gateways (AMG) and other devices. Among them, the local switch is responsible for implementing call services and resource control; the edge relay gateway implements signaling conversion and media stream conversion functions; the integrated access device and access media gateway realize the connection between the narrowband side telephone users and the broadband network, and realize IP access . The telephone users on the narrowband side are connected to each access gateway device through a subscriber line, and each access gateway device and edge relay gateway are connected to the IP MAN through a category-five line or a network cable. The edge trunk gateway is connected to the local exchange through E1/T1 trunk lines. The local exchange controls the call of the telephone user carried by the access gateway device through the edge trunk gateway to realize the voice service. Among them, the media gateway control protocol (MGCP), H.248 protocol, H.323 protocol or session initiation protocol (SIP) is used for communication between the edge trunk gateway and the access gateway device; the local switch and the edge trunk gateway use V5 communication Signaling Protocol, SS7, SS1 or Session Initiation Signaling Protocol (SIP) communication.

For the present invention, if the function of software dialing is implemented on the edge relay gateway, then after the user number is sent to the edge relay gateway by the access gateway device, the edge relay gateway queries the database according to the user number and obtains the corresponding matching scheme , and output the converted number to the exchange, thus completing the function of the software dialer. Similarly, if the software dialer function is implemented on the access gateway device, the access gateway device queries the database according to the user number, and after obtaining the corresponding matching scheme, outputs the converted number to the edge relay gateway, and the edge relay The gateway transparently transmits the number to the switch.

Referring to Fig. 2, in this embodiment, a dialer is realized by using software on the edge relay gateway device. A database is pre-established on the gateway, and the database is used to store user configuration information. The configuration information mainly includes the number change strategy, that is, how to Realize the transformation of the number according to the configuration of the user.

There is a management module on the gateway, which is used to receive the user number, query the database to complete the conversion of the user number, and finally report the number to the exchange. The database provides a corresponding interface for the management module to call and query.

Users are required to enter the following configuration information before use:

User ID: used to distinguish different users.

Transformation start position: From which digit to start the number transformation, the minimum digit is 1.

Number conversion index: the number of different number conversion methods, for reference by other tables.

Number conversion type: Indicates the method of number conversion, such as deleting numbers, inserting numbers, etc.

Number change length: the length of the number that needs to be changed.

Address property indication: indicate whether to change the address property of the number.

New number: the changed number, this field is only meaningful for transformation types such as "number change", "insert number" and "replacement".

The above-mentioned user information is stored in Table 1, Table 2 and Table 3. Table 1 is the association table between user identification and dialing mode, Table 2 is the dialing mode table, and Table 3 is the dialing mode table.

Table 1 - Association table between user ID and dialing mode User ID Transform start position Dial Method Index 100 1 1

Table 2 - Dialing Mode Table Dial Method Index Number Number Conversion Table Index 1 0 3 1 # 1

Table 3 - Number conversion table Number Change Index Number Transformation Type number conversion length address nature indication new number 0 no transformation 0 0 0xff 1 delete number 1 0 0xff 2 replace 1 0 17931 3 plug in 1 0 17931

After the user enters the above configuration information, the information is stored in the database "user identification and dialing mode association table", "dialing mode table" and "number conversion table" respectively. Users can enter information by telephone or WEB or apply for business in the business hall, and can also modify and delete it at the same time.

Example 1: There is a user, identified as 100, who is required to meet the following requirements:

The first digit of the dial is 0, and the insertion number is 17931

The first digit of the dial is "#", remove "#", and do not insert the number

In other cases do not insert a number.

After user requirements are configured through command line parameters, they are reserved in the table, as shown in Table 1, Table 2, and Table 3.

The main process of the present invention is referring to Fig. 3:

Step 10: When the management module of the edge trunk gateway receives the call event of the calling user, it queries the database to determine whether the user has been configured to be associated with the dialer.

When the calling user initially initiates a call, the database function is invoked to query the user ID-dialing mode association table (not shown) according to the user ID to determine whether the calling user has been configured to be associated with the dialer mode.

Step 20: According to the query result, it is judged whether the calling user has been configured to be associated with the dialer mode, if the judgment result is yes, go to step 30; if the judgment is no, go to step 60.

Step 30: The management module queries the database according to the dialed-out number of the calling user, and obtains a number conversion plan.

The management module invokes the function provided by the database, and inputs the user ID, number, and which number is the number. First, according to the user identification and the position sequence number of the current number, the dialing mode index is obtained from the user identification and dialing mode association table; then according to the dialing mode index and the current number, the number conversion table index is obtained from the dialing mode table; finally according to the number The conversion table index obtains the number conversion scheme specified by the relevant fields from the number conversion table.

Step 40: The management module processes the dialed number according to the number conversion scheme.

Step 50: The edge trunk gateway management module sends the number to the switch, and ends the dialing.

Step 60: The gateway management module directly sends the dial-out number of the user to the exchange, and ends the dialing.

When the management module queries the database, if the user does not configure it, the database returns 0, and the management module does not process the dialer. If the user has already configured it, the database returns the maximum value of "transformation start position", for example 2, then the management module will query the transformation schemes for the first two numbers in turn, and select the matching transformation scheme according to the number. Wherein, the number conversion scheme of each number executes step 30 to step 50 until the number with a specified number of digits is processed.

If the number does not match the conversion scheme, the number will be returned without any change.

Take Example 1 as an example:

After receiving the first number "0" entered by the user, first query the database. According to the user ID, the database finds that the user has number conversion settings, then looks up Table 1, and returns 1 after querying all the configuration items of the user, that is, the request The management module enters the user's first number. The management module inputs the user ID=100, the number=“0”, which is the “1” digit number. According to the input, the database looks up Table 1, and the index of the dialing method is 1, and then looks up Table 2 with this index, and there are two records. According to the number "0", confirm that the index of the number conversion table is 3, and thus find the table 3. According to the index 3, find that the corresponding record is inserted from the start digit, and the inserted number is "17931", then return "17931" to the management module. After receiving it, the management module sends the new number to the switchboard to complete the function of the software dialer.

Since the gateway equipment is managed by each telecom operator, the software dialer based on the gateway can ensure the centralized management and control of the user's dialer by the operator while realizing the function of the existing dialer. In addition, the software implementation scheme is simple and easy to use. Compared with hardware, the cost is lower, and it can meet other dialing requirements besides being applied to IP phone dialing.
