[0067] For the purpose, technical solutions and advantages of the present application to be clearer, further detailed description will be given to the present application in combination with the 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.

[0068] The application program downloading method provided by the embodiments of the present application can be applied to an application environment as shown in FIG. 1. Among them, the first terminal 102 and the second terminal 104 communicate with the core network device 106 through the network. The data storage system can store the data required to be processed by the core network device 106. The data storage system can be integrated on the core network device 106, or placed on the cloud or other network core network device. The first terminal 102 and the second terminal 104 belong to different operator networks. The first network is the operator network where the first terminal 102 is located, and the second operation management platform is the operation management platform of the network where the second terminal is located; the core network device 106 receives the application program downloading request of the first terminal, the data channel between the first terminal and the second terminal has been established, the application information provided by the second operation management platform is saved in the data channel warehouse of the first network, and the first application program list is generated according to the list generation rule of the first network, and the first application program list is sent to the first terminal. Finally, the application program downloading request generated by the first terminal based on the first application program list is received, the target application program is determined based on the application information provided by the second operation management platform saved in the data channel application warehouse of the first network, and the target application program is sent to the first terminal. Among them, the first terminal 102 and the second terminal 104 can be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things device can be a smart speaker, a smart TV, a smart air conditioner, a smart vehicle device, a projection device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The core network device 106 can be a stand-alone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0069] In an exemplary embodiment, as shown in FIG. 2, a method for downloading application is provided, which is taken as an example for the core network device 104 in FIG. 1, and includes the following steps S201 to S203. Wherein:

[0070] Step S201, receiving the application list download request of the first terminal; the first terminal and the second terminal have established a cross-network data channel.

[0071] Wherein, the first terminal can be understood as the terminal initiating the call service, or the terminal being called, and the second terminal is the same.

[0072] In some embodiments, when the first terminal initiates the call service to the second terminal, and successfully establishes a cross-network data channel, the first terminal prepares to download the application of the network where the second terminal is located, one of the application scenarios can be the scenario of video call, after the terminal A and the terminal B establish a cross-network call, further use of the application provided by other operators to improve the quality or interest of the call is needed. The core network device 106 only starts the function of receiving information when the first terminal and the second terminal successfully establish the data channel, and the core network device does not start the request receiving channel at other times, thereby saving the cost of device operation, and laying a foundation for subsequent generation of the first application list.

[0073] Step S202, sending the corresponding first application list to the first terminal; the first application list is generated based on the application information provided by the second operation management platform and the list generation rule of the network.

[0074] Wherein, the network is the network where the first terminal is located, and the second operation management platform is the operation management platform of the network where the second terminal is located; the data channel application warehouse of the network obtains the application information provided by the second operation management platform from the preset cross-network application management platform; the cross-network application management platform receives and stores the application information reported by multiple operation management platforms in accordance with the interconnection agreement.

[0075] The cross-network application management platform can be understood as a platform for managing applications in multiple operator networks, and can also store application information from different operator networks. The application information can include application program identification, application program version information, application program description information, and the application program itself. The second operation management platform can be understood as a platform for managing applications in the operator network in which the second terminal is located. In fact, the operation management platform can serve as an intermediate medium to coordinate communication between the data channel application repository (DCAR) and the cross-network application management platform. The data channel application repository (DCAR) can be understood as a storage repository for application information, which stores not only application information of the network but also application information of other networks. The first application program list can be understood as a table containing application program description information provided by the operator network corresponding to the second terminal.

[0076] In some embodiments, the core network device 104 generates a first application program list based on the application information provided by the second operation management platform and obtained from the cross-network application management platform, which is saved in the data channel application repository of the network, and the list generation rule of the network, and then returns the first application program list to the terminal for selection by the user using the terminal for program download. By generating a program naming list and returning it to the user for pre-selection, the lack of storage space caused by the need to download all programs is avoided, and targeted selection improves the interactivity with the user, thereby improving the user's service experience.

[0077] In other embodiments, the data channel application repository of the network also stores application information provided by other operator networks that complies with the interconnection agreement, which greatly ensures the success rate of calling other operator network services and realizes cross-network communication.

[0078] In step S203, the application program download request generated by the first terminal based on the first application program list is received, and the corresponding target application program is sent to the first terminal. The target application program is determined based on the application information provided by the second operation management platform and the version selection rule of the network, which is saved in the data channel application repository of the network.

[0079] The application program download request can be understood as a download request for a program selected by the user from the first application program list using the terminal, which also carries the application identification of the application program selected by the user, and can be multiple or one, but the final generated request is only one. The target application program can be understood as an application program that meets the requirements of both the user and the operator network.

[0080] In some embodiments, the core network device 104 receives an application download request generated by the first terminal based on the first application list, and uses the application information provided by the second operation management platform saved in the data channel application warehouse of the home network under the indication of the application download request, where the selected all candidate application programs in the program download request are met, but the candidate application programs have multiple versions, and then the target application program corresponding to the version is determined from the candidate application programs according to the version selection rule of the home network, and the target program is sent to the first terminal for the user to download and use. By the above-mentioned way, the target application program which meets the user's demand and is most suitable for the current version for easy use is determined, which greatly improves the user's service experience. Secondly, the data channel application warehouse of the home network stores the application information of the other network, which greatly guarantees the success rate of calling the other network business, and realizes the cross-network communication.

[0081] In the above-mentioned application download method, the core network device receives the application list download request of the first terminal, a data channel between the first terminal and the second terminal has been established, and then the corresponding first application list is sent to the first terminal, wherein the first application list is generated based on the application information provided by the second operation management platform of the second terminal network and the list generation rule of the home network saved in the data channel application warehouse of the first terminal network. The data channel application warehouse of the first terminal network obtains the application information provided by the second operation management platform from the preset cross-network application management platform, and the cross-network application management platform receives and stores the application information reported by multiple operation management platforms in accordance with the interconnection agreement; then the application download request generated by the first terminal based on the first application list is received, and finally the target application program determined based on the application information provided by the second operation management platform saved in the data channel application warehouse of the first terminal network and the version selection rule is sent to the first terminal. By storing the application information provided by multiple operation management platforms in accordance with the interconnection agreement in the cross-network application management platform in advance, when the terminal needs to download the cross-network application program, the target application program can be downloaded by using the pre-stored application information. Since these target application programs all meet the interconnection agreement, the cross-network business interaction can be realized, the success rate of the terminal's cross-network business call is improved, and the user's service experience is improved.

[0082] In one embodiment, the application list download request includes the network identifier of the second terminal network; the method further includes determining the second operation management platform based on the network identifier of the second terminal, and obtaining the list generation rule of the home network; obtaining the application information provided by the second operation management platform from the data channel application warehouse of the home network; generating the first application list based on the application information and the list generation rule.

[0083] The network identifier can be understood as an identity code of the operator network, and is also referred to as a calling identifier or a called identifier in other embodiments of the present application.

[0084] In some embodiments, the application program list download request received by the core network device 104 includes a network identifier of the operator network where the second terminal is located, the second operator management platform is determined according to the network identifier of the second terminal, the list generation rule of the operator network is obtained, then the application information provided by the second operator management platform is obtained from the data channel application warehouse of the operator network, the application information here refers to the naming information of the program, and finally the first application program list is generated according to the naming information of the program and the list generation rule. By generating a table information only listing the program names and pre-sending it to the user for selection, the situation of blindly filling a large amount of program information into the terminal and causing the terminal to crash and paralysis is avoided, which is conducive to the maintenance and use of various application programs, and thus the service experience of the user is improved.

[0085] In one of the embodiments, the application program download request includes an application identifier of the application program to be downloaded and a network identifier of the network where the second terminal is located; the method further includes determining the second operator management platform based on the network identifier of the second terminal, and obtaining the version selection rule of the operator network; obtaining the application information provided by the second operator management platform corresponding to the application identifier of the application program to be downloaded from the data channel application warehouse of the operator network; and determining the target application program based on the application information and the version selection rule.

[0086] In some embodiments, the application program download request received by the core network device 104 includes an application identifier of the application program to be downloaded and a network identifier of the operator network where the second terminal is located, then the second operator management platform is determined according to the network identifier of the second terminal, and the version requirement of the operator network for the application program is obtained, then the application information provided by the second operator management platform corresponding to the application identifier of the application program to be downloaded is obtained from the data channel application warehouse of the operator network, first, the application information satisfying the interconnection and interworking stored in the data channel warehouse of the operator network is selected, that is, the corresponding candidate application program is selected from the application program according to the application identifier of the application program to be downloaded, there are multiple versions, then the target application program is selected from them according to the version requirement of the operator network. Through the above determination method of the target application program, the requirements of the user for the application program are met, the transmission difficulty of the application program compatible with the operator network is smaller, and the application program of the other network can also be successfully used in the operator network, thereby improving the download success rate of the cross-network application program.

[0087] In an exemplary embodiment, as shown in FIG. 3, the data channel application warehouse of the home network is pre-provided with a first cross-network application cooperation module; the operation management platform of the home network is pre-provided with a first cross-network application scheduling module, and further comprises steps S301 and S302. Wherein:

[0088] In step S301, the first cross-network application cooperation module sends a first subscription update request to the cross-network application management platform through the first cross-network application scheduling module; the first subscription update request is used to subscribe to an application information update event of the second operation management platform; the cross-network application management platform is further used to send the first subscription update request to the pre-set second cross-network application scheduling module in the second operation management platform, and after receiving the application update information sent by the second cross-network application scheduling module, download the updated application information from the second cross-network application scheduling module and notify the first cross-network application scheduling module.

[0089] In step S302, the first cross-network application cooperation module acquires the updated application information of the second operation management platform sent by the cross-network application management platform through the first cross-network application scheduling module, and stores the updated application information into the data channel application warehouse of the home network.

[0090] Wherein, the first cross-network application cooperation module can be understood as a new place for the data channel application warehouse of the home network responsible for generating an application program list and selecting a target application program under a cross-operator network calling scenario, and it is an important part of realizing cross-operator network calling, and it is used to realize acquiring application information of other operators' networks; the first cross-network application scheduling module can be understood as an operation management platform of the home network responsible for synchronously uploading application information of the first operator network conforming to an interconnection protocol to the cross-network application management platform; the second cross-network application scheduling module is the same, and the cross-network application scheduling module is further used to monitor an application update event of the home network, and further used to send application update information to notify the cross-network application management platform.

[0091] In some embodiments, the first cross-network application cooperation module sends a first subscription update request for subscribing to an application update event of the second operation management platform to the cross-network application management platform through the first cross-network application scheduling module. The cross-network application management platform is further used to send the first subscription update request to the pre-set second cross-network application scheduling module in the second operation management platform, and after receiving the application update information sent by the second cross-network application scheduling module, download the updated application information from the second cross-network application scheduling module and notify the first cross-network application scheduling module that the application information has been updated. The first cross-network application cooperation module receives the updated application information of the second operation management platform sent by the cross-network application platform through the first cross-network application scheduling module, and stores the updated application information into the data channel application warehouse of the home network.

The user experience is improved, and it is ensured that the application information used by the user on different application platforms is the latest, and the inconsistent or outdated information is avoided.

[0093] In one embodiment, as shown in FIG. 4, steps S401 and S402 are included, wherein:

[0094] In step S401, the first cross-network application collaboration module receives, through the first cross-network application scheduling module, a second subscription update request from the second cross-network application collaboration module sent by the cross-network application management platform.

[0158] 3. A cross-network application cooperation module is added in the data channel application warehouse, which is responsible for generating an application list and selecting an application version in a cross-operator network call scenario. The application information of the operation and management platform in the home network is detected for updates. If yes, the updated information is reported to the cross-network application management platform, and the updated application information of other networks stored in the cross-network application management platform is obtained, so as to ensure real-time updating of the application information in the entire system and improve the service experience of users.

By pre-storing application information provided by multiple operation and management platforms and meeting the interconnection protocol in the cross-network application management platform, when a terminal needs to download a cross-network application program, the target application program can be downloaded by using the pre-stored application information. Since the target application program meets the interconnection protocol, cross-network service interaction can be realized, the success rate of the terminal in the cross-network service call is improved, and the service experience of users is improved.
