[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] The call subscription method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the communication device 100 communicates with the network element 200 through the network. The data storage system can store the data that the network element 200 needs to process. The data storage system can be integrated on the network element 200, or it can be placed on the cloud or other network servers. Among them, the communication device 100 is used to send a first query request to the network element 200 when receiving a subscription synchronization request sent by the service platform, receive a first query result returned by the network element 200 for characterizing the user's communication identification information, obtain the user's corresponding home domain name from the first query result, obtain the host name of the multimedia telephone platform corresponding to the home domain name according to the mapping relationship table and the load sharing rule, send a second query request to the network element 200, and receive the second query result returned by the network element for characterizing the communication address information, obtain the IP address corresponding to the host name from the second query result, and send the subscription session request corresponding to the number information to the multimedia telephone platform corresponding to the IP address to establish a call subscription with the multimedia telephone platform. Among them, the communication device 100 can be, but is not limited to, a wireless communication device with a data channel signaling function. The network element 200 can be a server with domain name conversion and routing addressing functions.

[0056] In an exemplary embodiment, Figure 2 As shown, a call subscription method is provided, which is applied to Figure 1 The communication device 100 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 202 to 210. Among them:

[0057] S202: When receiving a subscription synchronization request sent by the service platform, send a first query request to the network element; the first query request carries the user's number information.

[0058] Optionally, the communication device is a device with a data channel signaling function (DCSF), which can parse, encapsulate and forward various communication signaling. By adding a subscription module in DCSF, when receiving a subscription synchronization request sent by the service platform, in order to further determine the relevant information of the user, it is necessary to initiate a query to the network element, and query the communication identification information related to the user from the network element through the user number information. Among them, the subscription synchronization request can be understood as a single-user service contract information synchronization request, which refers to an instruction or message used to synchronize the service contract information of a single user between different devices or platforms. When the user signs a service on the contract platform, such as opening a 5G enhanced call service, the service platform initiates a subscription synchronization request to the communication device to ensure the consistency of the service information.

[0059] S204: Receive a first query result returned by the network element and used to represent the user's communication identification information, and obtain a home domain name corresponding to the user from the first query result.

[0060] Optionally, after receiving the first query request carrying the user number information, the network element performs a corresponding query operation and returns a first query result. The first query result includes the user's communication identification information, and the communication device extracts the user's corresponding domain name from it, where the domain name is the identifier of the specific network area or platform to which the user belongs.

[0061] S206: According to the mapping relationship table and the load sharing rule, the host name of the multimedia telephone platform corresponding to the home domain name is obtained.

[0062] Optionally, the communication device is pre-configured with a mapping relationship table and a load sharing rule, and the host name of at least one MultiMediaTelephonyApplicationServer (MMTel AS) corresponding to the user's home domain name can be determined according to the mapping relationship table, wherein the host name refers to the name used to identify and locate the MMTel AS in the network, that is, the unique identifier of the MMTel AS. When the home domain name corresponds to multiple MMTel ASs, the currently allocated MMTel AS is determined from them according to the load sharing rule.

[0063] S208: Send a second query request to the network element, receive a second query result returned by the network element and used to represent the communication address information, and obtain the IP address corresponding to the host name from the second query result; the second query request carries the host name.

[0064] Optionally, the communication device sends a second query request to the network element, wherein the second query request carries the host name of the MMTel AS, and the network element performs a corresponding query operation and returns a second query result, wherein the second query result includes the IP address corresponding to the carried host name.

[0065] S210: Sending a subscription session request corresponding to the number information to the multimedia telephone platform corresponding to the IP address to establish a call subscription with the multimedia telephone platform.

[0066] Optionally, after obtaining the IP address of the MMTel AS corresponding to the user's home domain name, the user's subscription session request is sent to the corresponding MMTel AS, thereby establishing a call subscription between the DCSF and the multimedia telephone platform. Through the collaborative work of the DCSF and the multimedia telephone platform, the core functions of the multimedia telephone service are realized, allowing users to conduct multimedia communications such as high-definition voice calls and video calls, meeting the contract subscription requirements of 5G enhanced call user services.

[0067] In the above-mentioned call subscription method, when the communication device receives a subscription synchronization request sent by the service platform, a first query request is sent to the network element, a first query result returned by the network element for characterizing the user's communication identification information is received, the user's corresponding home domain name is obtained from the first query result, and according to the mapping relationship table and the load sharing rule, the host name of the multimedia telephone platform corresponding to the home domain name is obtained, a second query request is sent to the network element, and a second query result returned by the network element for characterizing the communication address information is received, the IP address corresponding to the host name is obtained from the second query result, and the subscription session request corresponding to the number information is sent to the multimedia telephone platform corresponding to the IP address to establish a call subscription with the multimedia telephone platform, so as to realize the user's subscription to the multimedia telephone platform and meet the service contract subscription requirements of 5G enhanced call users. There is no need to separately configure user identification codes, thereby improving operation and maintenance efficiency.

[0068] In an exemplary embodiment, a mapping relationship table is used to characterize the correspondence between domain names in different regions and multimedia telephone platforms; a load sharing rule is used to characterize the resource allocation method of all multimedia telephone platforms corresponding to the same domain name; and the mapping relationship table and load sharing rules are pre-configured in the communication device.

[0069] Optionally, the mapping relationship table records the correspondence between the home domain names and multimedia telephone platforms in different regions. The multimedia telephone platform corresponding to the user's home domain name can be quickly queried through the mapping relationship table. Since the same home domain name may correspond to multiple multimedia telephone platforms, the configured load sharing rules can reasonably allocate resources and evenly distribute service requests to different multimedia telephone platforms. When performing maintenance operations such as system upgrades, capacity expansions, or equipment replacements, it is only necessary to modify and adjust the mapping relationship table and load sharing rules accordingly, without having to process the configuration of each user separately.

[0070] In this embodiment, the multimedia telephone platform corresponding to the home domain name can be quickly determined through the pre-configured relationship mapping table and load sharing rules, which reduces the amount of configuration data for the communication equipment, simplifies the configuration process, and thus improves operation and maintenance efficiency.

[0071] In an exemplary embodiment, the step of obtaining the host name of the multimedia telephone platform corresponding to the user's home domain name according to the mapping relationship table and the load sharing rules includes: obtaining multiple candidate host names corresponding to the user's home domain name according to the mapping relationship table; and determining the host name of the multimedia telephone platform corresponding to the user's home domain name from the multiple candidate host names according to the load sharing rules.

[0072] Optionally, the mapping relationship table stores the correspondence between the home domain names of different regions and the multimedia telephone platforms. By searching in the mapping relationship table, the candidate host names corresponding to the multiple multimedia telephone platforms corresponding to the home domain names of the user can be quickly obtained. After obtaining multiple candidate host names, the communication device determines which host name to use in the end according to the load sharing rules. For example, the load sharing rules may allocate tasks based on factors such as the current load conditions, processing capabilities or network bandwidth of each multimedia telephone platform. By evaluating the relevant indicators of each candidate host, the most suitable host name is selected to ensure that the user's request can be allocated to a multimedia telephone platform with sufficient resources and capable of efficiently processing the request.

[0073] In this embodiment, by obtaining multiple candidate host names corresponding to the user's domain name according to the mapping relationship table, and determining the host name of the multimedia telephone platform corresponding to the user's domain name from the multiple candidate host names according to the load sharing rules, it can ensure that the user's service request is accurately allocated to the most appropriate multimedia telephone platform, thereby accurately meeting the user's call subscription needs.

[0074] In an exemplary embodiment, the method further includes: upon receiving a subscription success response returned by the multimedia telephone platform, synchronizing the subscription success response to the service platform.

[0075] Optionally, after the communication device sends the subscription session request corresponding to the number information to the multimedia phone platform corresponding to the IP address, it receives the subscription response returned by the multimedia phone platform. When a successful subscription response is received from the multimedia phone platform, the successful subscription response is synchronized to the business platform, so that the business platform can obtain the user's successful subscription information in a timely manner.

[0076] In this embodiment, by synchronizing the successful subscription response returned by the multimedia telephone platform to the business platform when it is received, real-time information interaction between the business platform and the multimedia telephone platform can be ensured, reducing the increase in operation and maintenance costs due to information differences, and improving the efficiency and quality of operation and maintenance.

[0077] In an exemplary embodiment, Figure 3 As shown, a call subscription method is provided, which is applied to Figure 1 The network element 200 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps 302 to 304. Among them:

[0078] S302: In response to a first query request sent by the communication device, a first query result for characterizing the user's communication identification information is returned to the communication device; so that the communication device obtains the user's home domain name from the first query result, and obtains the host name of the multimedia telephone platform corresponding to the home domain name according to the mapping relationship table and the load sharing rule; the first query request carries the user's number information.

[0079] Optionally, the network element includes an Enum network element and a DNS network element, wherein the Enum network element is used to map telecommunication identifiers such as telephone numbers with other network resources or services to achieve conversion of telephone numbers to network addresses such as uniform resource identifiers (URIs), and the DNS network element is used to convert domain names into IP addresses.

[0080] Optionally, after receiving the first query request sent by the communication device, the Enum network element will search in the information stored internally thereof and return a first query result used to characterize the user's communication identification information to the communication device. After the communication device obtains the user's home domain name, it will find multiple candidate host names corresponding to the home domain name based on a pre-configured mapping relationship table, and determine a host name of the multimedia telephone platform corresponding to the user's home domain name from the multiple candidate host names according to the load sharing rules.

[0081] S304: In response to a second query request sent by the communication device, a second query result representing the communication address information is returned to the communication device, so that the communication device obtains the IP address corresponding to the host name from the second query result, and sends a subscription session request corresponding to the number information to the multimedia telephone platform corresponding to the IP address to establish a call subscription with the multimedia telephone platform; the second query request carries the host name.

[0082] Optionally, after receiving the second query request sent by the communication device, the DNS network element searches its database for the communication address information corresponding to the carried host name, and returns a second query result used to characterize the communication address information to the communication device. After the communication device obtains the IP address from the second query result, it sends a subscription session request to the multimedia telephone platform corresponding to this IP address, thereby establishing a call subscription with the multimedia telephone platform.

[0083] In this embodiment, the query request sent by the communication device is received by the network element, and the corresponding query result is returned to the communication device in a timely manner, so that the communication device establishes a call subscription with the multimedia telephone platform according to the returned query result, thereby realizing the user's subscription to the multimedia telephone platform and meeting the service contract subscription needs of 5G enhanced call users. There is no need to separately configure the user identification code, thereby improving the operation and maintenance efficiency.

[0084] In an exemplary embodiment, user communication identification information includes user identification information and home domain name information; in response to a first query request sent by a communication device, the step of returning a first query result used to characterize the user communication identification information to the communication device includes: obtaining a naming authority pointer record corresponding to the number information carried by the first query request; the naming authority pointer record is used to characterize a mapping rule for mapping the number information to the user identification information; according to the mapping rule, obtaining the user identification information corresponding to the number information; obtaining the home domain name corresponding to the user according to the user identification information, and returning the first query result to the communication device based on the user identification information and the home domain name.

[0085] Optionally, the first query request is a NAPTR query request. After receiving the first query request, the network element searches for a naming authority pointer record (i.e., a NAPTR record) corresponding to the number information carried in the first query request, wherein the NAPTR record is used to map a specific string (such as a telephone number) to a record in the DNS domain name system. According to the mapping rules contained in the naming authority pointer record, the user's number information is converted to obtain the corresponding user identification information. Further, according to the user identification information, the associated home domain name is searched, and the obtained user identification information and home domain name are combined to form a first query result, which is returned to the communication device. After receiving this result, the communication device can obtain the complete communication identification information about the user.

[0086] Exemplarily, the DCSF device initiates a NAPTR query to the Enum / DNS network element, carrying the user's E.164 number, such as 8612345678900, and receives a NAPTR query response returned by the Enum / DNS network element, including the user's identification information and home domain name, such as 8612345678900@home domain name.

[0087] In this embodiment, the network element responds to the first query request sent by the communication device, and returns the first query result used to characterize the user's communication identification information to the communication device, thereby ensuring the accuracy and consistency of the user's communication identification information, so that the communication device can quickly obtain the user's corresponding domain name, and when configuration adjustment or update is required, it can accurately find the corresponding configuration items for modification, thereby improving the efficiency of operation and maintenance.

[0088] In an exemplary embodiment, in response to a second query request sent by a communication device, the step of returning a second query result for characterizing communication address information to the communication device includes: obtaining an address record corresponding to the host name carried by the second query request; the address record includes an IP address corresponding to the host name; and based on the address record, returning the second query result to the communication device.

[0089] Optionally, the second query request is an A query. After receiving the second query request, the network element obtains an address record corresponding to the host name carried in the second query request, wherein the address record is used to characterize the mapping relationship between the host name and the IP address. The network element returns the second query result to the communication device according to the address record. After receiving the second query result, the communication device obtains the IP address therefrom to send the subscription session request to the multimedia telephone platform corresponding to the IP address.

[0090] In this embodiment, the network element responds to the second query request sent by the communication device, and returns the second query result used to characterize the communication address information to the communication device, so that the communication device can quickly obtain the IP address corresponding to the host name, and can realize the user's subscription to the multimedia telephone platform, and meet the service contract subscription needs of 5G enhanced call users. There is no need to separately configure the user identification code, thereby improving operation and maintenance efficiency.
