Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application. , not all examples. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The technical solutions of the present application will be described in detail below with specific examples. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Virtual number communication technology is a technology that provides temporary numbers to both parties in contact. The technology uses temporary numbers to hide the real numbers of both parties and protect the privacy of both parties. At present, this technology is widely used in Internet offline businesses such as online car-hailing, take-out ordering, and logistics intermediary. The logical scenarios include AX (one-way number protection), AXB (point-to-point two-way number protection), AXMN (many-to-many two-way number protection), and the like.

The virtual number communication technology consists of call processing technology and logic processing technology. The call processing technology is used to route the call request to a unified virtual number service processing platform when user A dials the virtual number X. The logic processing technology of the virtual number service processing platform converts virtual numbers into real numbers. Subsequently, the virtual number service processing platform connects the call request to the real number through the call processing technology.

In the prior art, after the user A dials the virtual number X, the virtual number communication service is usually realized through the following three virtual number communication technology methods:

Method 1: After user A dials the virtual number X, the virtual number communication service can trigger the virtual number service by subscribing the called CAMEL subscription information (Terminating-CAMEL Subscription Information, TCSI) smart service for the virtual number X to the virtual number X. After the virtual number service is triggered, the virtual number communication service can connect the call request according to the real number of the called party.

Method 2: After the user A dials the virtual number X, the virtual number communication service can trigger the virtual number service by subscribing the TCSI called intelligent service for the virtual number X. After the virtual number service is triggered, the virtual number communication service can issue a special routing code. Through the special routing code, the virtual number communication service enables the nationwide call request to be routed to the unified virtual number service processing platform. After the virtual number service processing platform performs logical processing on the call request, it initiates the call request to the call of the real called party.

Method 3: The scheme utilizes the mobile network CS (Circuit Switch, circuit switching) network standard process to realize the centralized call processing technology, and through the virtual mobile communication switching center/visitor location register (Mobile Switching Center/Visitor Location Register, MSC/VLR) network Meta performs location update on virtual number X. When user A dials virtual number X, the virtual VLR feeds back the roaming number of a specific number segment. The virtual number communication service routes the nationwide call requests to the unified virtual number service processing platform through the roaming number of the specific number segment. After the virtual number service processing platform performs logical processing on the call request, it initiates the call request to the call of the real called party.

In the process of using the above virtual number communication service, solutions 1 and 2 require TCSI called smart service subscription for virtual number X. The realization of the TCSI called smart service subscription requires the modification of the operator's number account opening system and the TCSI templates of each home subscriber server (Home Subscriber Server, HSS network element) in the country. Obviously, if the use of the virtual number communication service needs to be implemented nationwide, extremely high renovation costs are required. In addition, the virtual number communication service realized through the TCSI called smart service subscription cannot obtain the call medium.

Compared with Schemes 1 and 2, Scheme 3 does not need to transform the network, and is the best scheme among them. However, the call processing technology in this solution is implemented through the CS network standard process, and its call processing needs to be performed in the traditional CS network. Therefore, in the virtual number communication service process, the call request needs to enter the IMS network from the CS network, and then return from the IMS network to the CS network to complete the process of the call request. With the increase in the proportion of mobile communication LTE voice bearer (Voice Over Long-Term-Evolution, Volte) users, a large number of call requests need to enter and exit the CS network from the IP Multimedia Subsystem (IMS) network, resulting in waste of circuit resources and call time. increase the problem of delay.

In view of the above-mentioned problems in the prior art, the present application proposes a virtual number communication method and system. The virtual number communication system proposed in this application includes an IMS network and a virtual Serving Call Session Control Function (SCSCF) network element. Among them, the virtual SCSCF network element is established in the IMS network, can be connected with other network elements in the IMS network, and supports SIP protocol, DIAMETER protocol, ENUM/DNS protocol and other protocols. The virtual SCSCF network element initiates a service assignment request to at least one home HSS network element, so as to realize the authentication and registration of the virtual number in the home HSS network element. The virtual SCSCF network element uses the authentication and registration method, so that when the user uses the virtual number, the home SCSCF network element where the calling user is located can query the virtual SCSCF network element through the home HSS network element of the virtual number. meta information. Furthermore, the home SCSCF network element where the calling user is located can be routed to the virtual SCSCF network element through the information of the virtual SCSCF network element. When the virtual SCSCF network element receives the call request including the called virtual number initiated by the calling user, the virtual SCSCF network element can obtain the corresponding called real number by parsing through the virtual number logic processing module. Furthermore, according to the real number of the called party, the virtual SCSCF network element can initiate a call request according to the information of the real number.

The virtual SCSCF network element includes a virtual number call processing module and a virtual number logic processing module. The virtual number logic processing module is configured to determine the corresponding called real number according to the called virtual number included in the call request. The virtual number call processing module is used to acquire the call request initiated by each home CSCF network element, and initiate a call request to its corresponding home CSCF network element according to the called real number.

The virtual SCSCF network element is connected to the ENUM/DNS, and is used to implement a number name authority pointer (Naming Authority Pointer, NAPTR) query, a service domain name service record (Service record, SRV) query, a host name address query, and the like. The virtual SCSCF network element is connected with the MGCF/MGW, and is used to be compatible with CS network calls when the user terminal is not in the IMS network.

The general intelligent peripheral device is connected with the virtual SCSCF network element through the IMS network, and is used to obtain the call medium.

Specifically, the second home HSS network element searches the second home HSS network element for its corresponding virtual SCSCF network element host name according to the called virtual number in the address information request.

After completing the query of the address information request, according to the query result, the second home HSS network element determines the virtual SCSCF network element host name corresponding to the called virtual number. The second home HSS network element feeds back address information to the second home ICSCF network element. The address information includes the virtual SCSCF network element host name of the called virtual number obtained by query.

S104: The second home ICSCF network element acquires the address information fed back by the second home HSS network element, and initiates a second call request to the virtual SCSCF network element according to the address information.

In this embodiment, the second home ICSCF network element acquires the address information fed back by the second home HSS network element after sending the address information request to the second home HSS network element. The address information includes the virtual SCSCF network element host name of the called virtual number.

According to the host name of the virtual SCSCF network element, the second home ICSCF network element can determine the route to the virtual SCSCF network element. The second home ICSCF network element initiates a second call request, and routes the second call request to the virtual SCSCF network element.

The second call request includes information such as the real number of the calling party, the virtual number of the called party, the host name of the virtual SCSCF network element, and the address of the virtual SCSCF network element.

Furthermore, through the address of the called real number, the virtual SCSCF network element initiates a third call request to the called user.

In the virtual number communication method provided by the present application, the second home ICSCF network element obtains the first call request initiated by the first home SCSCF network element, and initiates an address information request to the second home HSS network element. Wherein, the first call request includes the called virtual number. The first home SCSCF network element is the home SCSCF network element where the calling real number is registered, the second home ICSCF network element is the home ICSCF network element where the called virtual number is registered, and the second home HSS network The element is the HSS network element of the home where the called virtual number is registered.

FIG. 3 shows a signaling interaction diagram of another virtual number communication method provided by an embodiment of the present application. On the basis of the embodiments shown in FIG. 1 and FIG. 2 , as shown in FIG. 3 , the method of this embodiment may include the following steps:

S201. The first home SCSCF network element initiates a first call request, the call request includes the calling real number and the called virtual number, and the first home SCSCF network element is the home SCSCF network element where the calling real number is registered.

S202. The first home ICSCF network element acquires the first call request initiated by the first home SCSCF network element, and initiates an address information request to the first home HSS network element, where the first home ICSCF network element is the called virtual number The registered home ICSCF network element, the address information request includes the called virtual number, and the first home HSS network element is the home HSS network element where the called virtual number is registered.

S204: The first home ICSCF network element acquires the address information fed back by the first home HSS network element, and initiates a second call request to the virtual SCSCF network element according to the address information.

S205, the virtual SCSCF network element acquires the second call request initiated by the first home ICSCF network element, and determines the called real number according to the called virtual number.

The implementation manners of steps S201 to S205 are similar to those of steps S101 to S105 in the embodiment of FIG. 2 , and details are not described herein again in this embodiment.

S206, the virtual SCSCF network element initiates a request for attribution of the called real number to the ENUM/DNS.

In this embodiment, after acquiring the real number of the called party according to step S105, the virtual SCSCF network element needs to acquire the address of the real number. In the IMS network, ENUM/DNS is used to implement query services such as number NAPTR query, service domain name SRV query, and host name address query. Therefore, the virtual SCSCF network element can obtain the attribution of the called real number by initiating an attribution query request of the called real number to the ENUM/DNS. The real number attribution query request includes the called real number.

S207: The virtual SCSCF network element obtains the second home ICSCF network element fed back by the ENUM/DNS, where the second home ICSCF network element is the home ICSCF network element where the called real number is registered.

In this embodiment, after obtaining the called real number attribution query request initiated by the virtual SCSCF network element, the ENUM/DNS queries the called real number according to the called real number in the called real number attribution query request. attribution. The ENUM/DNS determines the home CSCF network element of the called real number according to the home location, and determines that the home CSCF network element is the second home CSCF network element. The second home CSCF network element may include a second home ICSCF network element, a second home HSS network element, and a second home SCSCF network element.

The ENUM/DNS feeds back the attribution of the called real number to the virtual SCSCF network element. The virtual SCSCF network element obtains the second home ICSCF network element, and determines the address of the second home ICSCF network element.

S208, the virtual SCSCF network element initiates a third call request to the second home ICSCF network element.

In this embodiment, after acquiring the second home ICSCF network element according to step S105, the virtual SCSCF network element initiates a third call request to the second home ICSCF network element. The second call request includes information such as the calling real number, the called virtual number, the called real number, and the address of the second home ICSCF network element.

S209, the second home ICSCF network element determines whether the called real number is in the IMS network according to the called real number.

In this embodiment, after acquiring the third call request, the second home ICSCF network element acquires the called real number in the third call request. The second home ICSCF network element determines whether the called real number is in the IMS network by querying the called real number.

Since the IMS network does not support the 2G/3G network, when the UE of the called user cannot use the 4G or 5G network, the called real number cannot receive the third call request through the IMS network. Alternatively, the user UE usually includes an IMS network switch button, and when the user turns off the IMS network on the UE, the called real number cannot receive the third call request.

Therefore, in order to ensure that the called user can receive the third call request, the second home ICSCF network element will judge whether the called real number is in the IMS network.

S210. If the called real number is in the IMS network, the second home ICSCF network element initiates a fourth call request to the called terminal through Volte. Or, if the called real number is not in the IMS network, the second home ICSCF network element initiates a fourth call request to the called terminal through the CS network.

In this embodiment, when the second home ICSCF network element determines that the called real number is in the IMS network, the second home ICSCF network element sends a fourth call request to the called real number through the IMS network. The call request implemented through the IMS network may be a Volte communication request. Through this Volte communication, users can realize new services such as high-definition voice and video, and achieve the technical effect of reducing call delay.

When the second home ICSCF network element determines that the called real number is not in the IMS network, the second home ICSCF network element cannot contact the called real number through the IMS network. At this time, the second home ICSCF network element may initiate a fourth call request to the called terminal through the CS network, thereby realizing normal communication.

In the virtual number communication method provided by the present application, the second home ICSCF network element obtains the first call request initiated by the first home SCSCF network element, and initiates an address information request to the second home HSS network element. The second home ICSCF network element obtains the address information fed back by the second home HSS network element, and initiates a second call request to the virtual SCSCF network element according to the address information. The virtual SCSCF network element acquires the second call request initiated by the second home ICSCF network element, determines the called real number according to the called virtual number, and initiates a third call request according to the called real number. The virtual SCSCF network element initiates an attribution query request of the called real number to the ENUM/DNS. The virtual SCSCF network element obtains the second home ICSCF network element fed back by the ENUM/DNS, and the second home ICSCF network element is the home ICSCF network element where the called real number is registered. The virtual SCSCF network element initiates a third call request to the second home ICSCF network element. The second home ICSCF network element determines whether the called real number is in the IMS network according to the called real number. If the called real number is in the IMS network, the second home ICSCF network element initiates a fourth call request to the called terminal through Volte. Or, if the called real number is not in the IMS network, the second home ICSCF network element initiates a fourth call request to the called terminal through the CS network. In this application, the virtual SCSCF network element directly interacts with the IMS network to realize the registration and use of the virtual number in the IMS network. During the interaction between the virtual SCSCF network element and the IMS network, the standard protocols and procedures of the IMS network are used. The use of this standard protocol and process makes the IMS network no longer need to be transformed. That is, the virtual SCSCF network element can directly use the virtual number to initiate the call request in the IMS network. At the same time, the use of the IMS network enables call requests to be processed through Volte, which reduces delay and realizes new services such as high-definition voice and video. In addition, the second home ICSCF network element ensures the execution of the communication request by being compatible with the IMS network and the CS network.

On the basis of the above embodiment, before implementing the above virtual number communication method, the present application also needs to generate the association between the calling user, the called user and the virtual number. When the business platform needs to realize Internet offline services such as online car hailing, takeaway meal ordering, and logistics intermediary, the business platform can determine, according to the business order, that there is a virtual number communication requirement between the customer and the salesperson in this business service. Furthermore, according to the communication requirement of the virtual number, the service platform can establish the association between the customer number and the salesperson number and the virtual number. The process may specifically include the following steps:

Step 1. Obtain business requirements. The business requirements are virtual number communication requirements. The business requirements include calling information and called information. The calling information includes the calling terminal and the real number of the calling party. The called information includes the called terminal and the real number of the called party. Number.

In this step, the business platform obtains business requirements, and the business requirements may be business orders. For example, ride orders for online car-hailing, delivery orders for take-out orders, etc. The service requirement is a virtual number communication requirement. For example, when the business requirement is an online car-hailing ride order, the passengers and drivers in the order will have communication requirements. However, in order to protect the privacy of both the passenger and the driver, the communication may be a virtual number communication.

When the business platform obtains the business requirement, such as an order, the business platform can determine the two parties that need to communicate with the virtual number according to the order. During the communication process, both parties can be the calling or called party. In order to facilitate the distinction, the service platform may determine that one party is the calling user and the other party is the called user. In the above-mentioned embodiment, the application determines the calling user and the called user. However, in practice, the calling user may be any one of the two communication parties. Alternatively, the service platform may determine that the two parties are user A and user B. The distinction between the two users does not affect the implementation of this application.

Step 2. According to the service requirements, establish a service list. The service list includes the calling information, the called information and the called virtual number. When the calling terminal initiates a call request to the called terminal, the calling terminal sends the called virtual number to the called party. Call the terminal to initiate a call request.

In this step, after acquiring the business requirement, the business platform creates a business order according to the business requirement. The service list includes calling information, called information and called virtual number. The called virtual number is a virtual number selected by the service platform from preset virtual code numbers. Specifically, the service platform can determine the virtual number it selects by calculation according to the preset rules and the real number of the calling party and the real number of the called party. Or the service platform can randomly select a virtual number from preset virtual numbers.

When the calling user initiates a call request to the called user through the calling terminal, the calling user can initiate the call request by dialing the virtual number.

FIG. 4 shows a signaling interaction diagram of still another virtual number communication method provided by an embodiment of the present application. On the basis of the embodiments shown in FIGS. 1 to 3 , as shown in FIG. 4 , before the above-mentioned virtual number communication is implemented, after the virtual SCSCF network element is connected to the IMS network, the virtual SCSCF network element needs to communicate with each other in the IMS network. The virtual number is registered in the home CSCF. For example, when the processing device of the service platform is set in Zhejiang, in order to facilitate the processing of the service platform, the service platform may use a preset virtual number whose home is Zhejiang. Alternatively, when the origin of the service requirement is in Shanghai, the service platform may use a preset virtual number whose home location is Shanghai according to the origin of the service requirement. Therefore, in order to meet various logical requirements and implement the virtual number communication service nationwide, the virtual SCSCF network element needs to register virtual numbers in each home CSCF in the IMS network. The method of this embodiment may include the following registration steps:

S301. The virtual SCSCF network element sends a service assignment request to the DRA, and the DRA is used to authenticate the service assignment request.

In this embodiment, the virtual SCSCF network element sends a service assignment request to each home HSS according to its preset instruction. Before the virtual SCSCF network element sends the service assignment request to each home HSS, the service assignment request needs to pass through the DRA.

DRA can implement the translation and transfer of destination addresses through Diameter signaling, and can also be used to implement operations such as authentication, location update, and billing management.

After the DRA obtains the service assignment request sent by the virtual SCSCF network element, it can implement the translation and transfer of the destination address of the service assignment request according to the Diameter signaling in the service assignment request.

The DRA determines the route of the service dispatch request by translating and forwarding the destination address. In addition, the DRA may also assign the requested authentication through the service. In the authentication process, unqualified service assignment requests can be filtered out, thereby preventing abnormal, false or erroneous service assignment requests from being sent to each home HSS.

In an example, the service assignment request includes at least one virtual number and a virtual SCSCF network element host name.

S302. When the service assignment request is true, the DRA forwards the service assignment request to the home HSS network element.

In this embodiment, when the DRA determines that the service assignment request is a correct service assignment request through authentication, the DRA sends the service assignment request to the corresponding home HSS according to the destination address in the service assignment request.

S303. After saving the virtual number and the virtual SCSCF network element, the home HSS network element feeds back a service assignment response.

In this embodiment, after the home HSS network element receives the service assignment request, it is assumed that the virtual number in it has been authenticated and registered through the virtual SCSCF. The home HSS saves the virtual number and its corresponding virtual SCSCF network element in the home HSS network element according to the service assignment request.

S304, the DRA obtains the service assignment response, and when the feedback service assignment response is true, the DRA forwards the service assignment response to the virtual SCSCF network element.

In this embodiment, when the home HSS network element feeds back a service assignment response to the virtual SCSCF network element, the service assignment response also needs to be authenticated by the DRA. Through the authentication operation, the virtual SCSCF network element can be effectively prevented from receiving an abnormal service assignment response.

In the virtual number communication method provided by the present application, the virtual SCSCF network element sends a service assignment request to the DRA, and the DRA is used to authenticate the service assignment request. When the service assignment request is true, the DRA forwards the service assignment request to the home HSS network element. After saving the virtual number and the virtual SCSCF network element, the home HSS network element feeds back a service assignment response. The DRA obtains the service assignment response, and when the feedback service assignment response is true, the DRA forwards the service assignment response to the virtual SCSCF network element. In the present application, the virtual SCSCF network element technology enables the registration of virtual numbers to omit complex processes such as bidirectional authentication and Evolved Packet Core (EPC) dedicated bearer establishment. At the same time, the access process of the user terminal (UserEquipment, UE) is hidden, thereby simplifying the registration process and avoiding the risk of leakage of the authentication quintuple.
