The number processing method provided in the embodiment of the present application is described in detail below with reference to fig. 3, and as shown in fig. 3, the number processing method includes:

s301, the CSCF receives a first number from the VoLTE VPN platform.

Optionally, the first number is a number generated by the VoLTE VPN platform according to the called number. The called number includes a trombone number or a short number.

Illustratively, when the called number is a trombone number, the called number is 1XXXXXYYYYY; when the called number is a short number, the called number is 95013.

S302, the CSCF sends the first number to a telephone number mapping domain name resolution system (Ttlephone Number Mapping-Domain Name System, ENUM-DNS) in case the first number comprises a number prefix. Accordingly, the ENUM-DNS receives a first number.

Optionally, the number prefix includes a country code and an area code.

Illustratively, the number prefix is 86531; the first number is 8653195013.

It should be explained that 86 is a country code and 531 is an area code.

Optionally, the ENUM-DNS includes a domain name system (Domain Name System, DNS) network element and a telephone number mapping work group (Telephone Number Mapping working group, ENUM) network element.

Optionally, the DNS network element is configured to translate the first number into a third number identifiable by the ENUM network element, and the ENUM network element is configured to delete a number prefix in the third number.

In a possible implementation, the CSCF sends the first number to a DNS network element in ENUM-DNS.

It should be explained that the CSCF sends the first number to a DNS network element in ENUM-DNS. The DNS network element translates the first number into a third number identifiable by the ENUM network element and sends the third number to the ENUM network element. And deleting the number prefix in the third number by the ENUM network element to obtain a fourth number, and sending the fourth number to the DNS network element. The DNS network element translates the fourth number into a second number recognizable by the CSCF and sends the second number to the CSCF.

S303, deleting the number prefix in the first number by the ENUM-DNS to obtain a second number.

In one possible implementation, the ENUM-DNS deletes the first number prefix, generates a second number, and the first number includes the number prefix and the second number.

In another possible implementation, ENUM-DNS replaces the number prefix portion in the first number with a blank symbol, resulting in the second number.

Illustratively, when the first number is 8653195013, the second number is 8653195013.

S304, ENUM-DNS sends the second number to CSCF. Correspondingly, the CSCF receives the second number.

In one possible implementation, the ENUM-DNS sends the second number to the CSCF over an encrypted channel.

And S305, the CSCF sends the second number to the IMS.

Optionally, the IMS includes a BGCF and an MGCF.

In one possible implementation, the CSCF sends the second number to the BGCF.

It should be explained that the BGCF selects MGCF for IMS to PSTN call based on the second number, and the BGCF sends the second number to MGCF. The MGCF realizes the interaction between the IMS core control surface and PSTN through the second number.

In a possible implementation, in conjunction with fig. 3, as shown in fig. 4, before S301, the CSCF receives the first number from the VoLTE VPN platform, the CSCF is further configured to obtain and process a call request from the user terminal. The procedure of the call request of the user terminal can be realized by the following S401-S402.

S401, CSCF receives call request from user terminal.

In a possible implementation, the CSCF receives a call request from the user terminal through the access network device.

Optionally, the user terminal is a terminal to which the VoLTE VPN user belongs; the access network device comprises at least one of the following: base station, micro base station, macro base station, wireless fidelity (Wireless Fidelity, WIFI) access point.

S402, the CSCF sends first indication information to the VoLTE VPN platform.

The first indication information is used for indicating the VoLTE VPN platform to add the number prefix in the short number.

Optionally, the first indication information further includes a called number.

It should be explained that, as shown in fig. 5, after the user terminal makes a call request to the CSCF, the VoLTE VPN platform is triggered and then automatically detects the type of the called number. And adding a number prefix before the short number when the called number is the short number. The CSCF may send the short number with the number prefix added to the BGCF, and the BGCF may send the short number with the number prefix added to the MGCF, thereby implementing outgoing calls. Therefore, unified management and anti-harassment interception of the called number can be realized.

For example, the called user terminal can intercept the short number of the specific area code and the country code, so as to avoid the called terminal from being harassd by the telephone.

The scheme at least brings the following beneficial effects: in the embodiment of the application, before the CSCF receives the first number from the VoLTE VPN platform, the CSCF receives the called number from the user terminal. The CSCF starts number identification according to the received first information, so that the VoLTE VPN can process the called number in time, and unified management and anti-harassment interception of the called number are realized.

In one possible implementation, as shown in fig. 6 in conjunction with fig. 4, the CFCS of the present application may also detect the called number. The procedure of CSCF called number can be implemented specifically by the following S601-S602.

S601, CSCF detects the called number and determines the type of the called number.

The called number type comprises a trombone number and a short number; the call request includes the called number to be called.

In a possible implementation, the CSCF detects the number of digits of the called number and determines the type of the called number based on the number of digits of the called number.

Optionally, if the number of digits of the called number is greater than or equal to the threshold, the CSCF determines that the called number is a trombone number; if the number of digits of the called number is smaller than the threshold value, the CSCF determines that the called number is a short number.

Illustratively, the threshold is 11. If the number of digits of the called number is greater than or equal to 11, the CSCF determines that the called number is a trombone number; if the number of digits of the called number is less than 11, the CSCF determines that the called number is a short number.

In another possible implementation, the CSCF detects the first value of the called number and determines the type of the called number based on the first value of the called number.

Optionally, if the first numerical value of the called number is the target numerical value, the CSCF determines that the called number is a trombone number; if the first numerical value of the called number is not the target numerical value, the CSCF determines that the called number is a short number.

Illustratively, the target value includes 1. If the first numerical value of the called number is 1, the CSCF determines that the called number is a trombone number; if the first digit value of the called number is not 1, the CSCF determines that the called number is a short number.

S602, if the called number is a short number, the CSCF sends second indication information to the VoLTE VPN platform.

The second indication information is used for indicating the VoLTE VPN platform to transmit the called number to the CFCS.

Optionally, the second indication information is used for indicating the VoLTE VPN platform to stop detecting the type of the called number, and directly and transparently transmitting the called number.

It should be explained that the VoLTE VPN receives the second indication information, stops detecting the type of the called number according to the second indication information, and sends the called number as the first number to the CSCF.

Optionally, the second indication information is used for indicating the VoLTE VPN platform to stop detecting the type of the called number in a preset time period, and the called number is sent to the CSCF as the first number. Thus, accurate short number determination processing can be realized.

The scheme at least brings the following beneficial effects: in the embodiment of the application, the CSCF detects the called number and determines the type of the called number. Therefore, the VoLTE VPN platform is indicated to transmit the called number, and in this way, the first number can be a number without a number prefix.

In a possible implementation manner, as shown in fig. 7 in connection with fig. 3, the procedure of S302 CSCF sending the first number to ENUM-DNS may be implemented specifically by the following S701.

S701, the CSCF sends the first number and the third indication information to the ENUM-DNS.

Wherein third indication information is used for indicating the ENUM-DNS to delete the number prefix in the first number.

In the embodiment of the application, the CSCF receives a first number from a VoLTE VPN platform. In the case where the first number includes a number prefix, devices downstream from the VoLTE VPN platform may not be able to recognize, process the first number. In the application, the CSCF sends the first number to the ENUM-DNS, and the ENUM-DNS can delete the number prefix in the first number to obtain the second number. The CSCF receives and sends the second number without the number prefix to the IMS, so that a downstream device of the VoLTE VPN platform in the IMS can directly process the second number, thereby implementing a call of the user terminal. Therefore, the method and the device can improve the compatibility of VoLTE VPN calls.
