Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
In order to solve the problems in the prior art, the present application provides a method for a public network terminal to dial back a private network terminal, as shown in fig. 1, the method includes the following steps:
step 101: n reserved numbers (X1, X2... Xn) are reserved in the private network as an internal resource pool, and n public network numbers (Y1, Y2... Yn) are applied to the public network.
Step 102: and configuring the binding relationship between the n reserved numbers and the n public network numbers in the internal resource pool on the PSTN/PLMN voice gateway or PBX and other equipment.
For example: x1 and Y1, X2 and Y2, and. Therefore, the n public network numbers can be shared by users in the private network in a time-sharing manner, so that the application of massive public network numbers is avoided.
Step 103: when a private network terminal calls a public network terminal during the association of the private network number and Xi (1< ═ i < ═ n), the command scheduling center modifies the calling number of the call into a public network number Yi bound with the reserved number Xi associated with the private network number of the private network terminal, so that the incoming call is displayed on the public network terminal as the public network number Yi bound with the Xi associated with the private network number of the private network terminal (1< ═ i < > n), and the public network terminal dials back to Yi and can directly connect the corresponding private network terminal. The private network number and the private network terminal are in one-to-one correspondence.
The private network system accessing the PSTN is exemplified below.
Suppose that:
800001, 800002, …, internal resource pool number reserved for private network, used for connecting with public network terminal;
84935001, 84935002 and … are public network numbers applied to the public network;
configuring the binding relationship between the public network number and the private network internal resource pool number on the voice gateway/PBX, and the form can be shown as table 1:
TABLE 1
| Private network resource pool number | Public network number |
| 800001 | 84935001 |
| 800002 | 84935002 |
| … | … |
When private network user A (private network number: 1101111) and public network terminal (public network number: 137 XXXXXXX) need to call directly each other, the command and dispatch center inside the private network selects number 800001 from the internal resource pool to associate with private network user A's private network number 1101111, as shown in Table 2:
TABLE 2
| Private network resource pool number | Associated private network subscriber number | Association setup time |
| 800001 | 1101111 | 201811281501 |
| 800002 | NA | NA |
| … | … | … |
During the association period shown in table 2, the private network terminal and the public network terminal incoming/outgoing call flow is shown in fig. 2, and includes two major parts, namely, a private network terminal outgoing call and a public network terminal incoming call, which are described below.
Calling by the private network terminal:
step 11: the private network terminal initiates a call to the command dispatching center, and the called number is a public network number: 0137XXXXXXXX, the calling number is the private network number of the private network terminal: 1101111.
step 12: the command dispatching center selects a number 800001 from the internal resource pool to be associated with a private network number 1101111 of the private network terminal, records the association relationship, and initiates a call to the voice gateway/PBX, wherein the called number is a public network number: 0137XXXXXXXX, calling number private network number: 800001.
step 13: the voice gateway/PBX determines that the public network number bound to the private network number 800001 is 84935001 according to the binding relationship in table 1, modifies the calling number of the call to 84935001, and then continues to initiate the call to the PSTN.
Step 14: PSTN to public network number: 0137 XXXXXXXXX initiates a call, and the calling number displayed on the public network terminal is 84935001.
Calling a public network terminal:
step 21: the public network terminal initiates a call to the PSTN, and the called number is a public network number: 84935001, the calling number is the public network number of the public network terminal: 137 XXXXXXXX.
Step 22: the PSTN forwards the call to the voice gateway/PBX device.
Step 23: and the voice gateway/PBX equipment determines that the private network number bound with the public network number 84935001 is 800001 according to the binding relation in the table 1, and initiates a call to the private network number 800001 to the command and dispatch center.
Step 24: and the command dispatching center determines that the private network number corresponding to the private network number 800001 is 1101111 according to the recorded association relationship, and then initiates a call to the private network terminal corresponding to the private network number 1101111.
In the above process, the command and dispatch center may formulate a policy disassociation relationship (i.e., formulate a condition for disassociating the relationship), for example, when a task is completed and the association exceeds a certain time, the association relationship between the private network number and the reserved number is disassociated, and after the disassociation relationship is disassociated, the reserved number is reintroduced into the internal resource pool for associating with other private network users.
Corresponding to the above method, the present application provides a system for implementing callback of a private network terminal by a public network terminal, where the system includes devices that refer to fig. 2, and includes: PSTN/PLMN pronunciation gateway or PBX equipment, command dispatch center, private network terminal and public network terminal, wherein:
reserving n reserved numbers in the private network, and applying n public network numbers to the public network, wherein n is greater than 1;
the PSTN/PLMN voice gateway or PBX equipment is used for configuring and storing the binding relationship between the n reserved numbers and the n public network numbers;
the command dispatching center is used for maintaining the association relationship between the private network number of the private network terminal and the reserved number, and when the private network terminal calls the public network terminal in the period of associating the private network number with the reserved number Xi, the command dispatching center modifies the calling number of the call into the public network number Yi bound with the reserved number Xi associated with the private network number of the private network terminal;
wherein, 1< ═ i < ═ n.
Preferably, when the public network terminal dials back the public network number Yi, the PSTN/PLMN voice gateway or the PBX device is configured to determine, according to the binding relationship, a reserved number Xi corresponding to the public network number Yi, and the command and scheduling center is configured to determine, according to the reserved number Xi, a private network number associated therewith, and connect a call to a private network terminal corresponding to the private network number.
Preferably, the command and dispatch center is further configured to formulate a condition for disassociating the relationship;
when the conditions are met, the command and scheduling center releases the association relationship between the private network number and the reserved number;
and after the association relationship is released, the corresponding reserved number is brought into the internal resource pool again for being associated with other private network terminals for use.
Preferably, the conditions include, but are not limited to: task completion, association over a certain time, etc.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
