Application program updating method and device based on satellite message

Abstract

The invention provides an application program updating method and device based on a satellite message, and the method comprises the steps that a current terminal receives message information sent by a monitoring master station through a satellite, and the message information comprises interlayer difference information of a current version and a new version of an existing application program in the current terminal; applying the interlayer difference information to the target hierarchy of the current version to form an update hierarchy; and recombining the updated hierarchy of the current version and the existing hierarchy which is not updated to form an updated application program. In this way, application programs of services deployed in areas without available network connections or only with weak links can be updated, and application programs of multiple services in the same area can be synchronously updated while the network transmission data volume is reduced.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of satellite communication, and more specifically, relate to a method and device for updating an application program based on a satellite message. Background technique [0002] Applications and services may be deployed anywhere on the planet, including some regions with no available network connections or only weak links; developers of applications and services need to provide updates for those deployed in the above locations. Typical service pack size is 50-100MB, and application size is 500-1500MB. The traditional application and service update methods, including the transmission of physical media and the transmission of updates through the network, are not suitable for the above scenarios; if multiple locations in the above scenarios need to update applications and services, it will be more difficult to update applications and services .

AI Technical Summary

Problems solved by technology

[0007] 1. At present, most of the program packages iteratively use the full update method. Only the transfer of patches will use the incremental update method, and the redundancy in the transfer process is relatively large;

[0008] 2. For the program packages that adopt the incremental update method, it is necessary to return the package version deployed by the terminal to the service sending end. The sending end compares the version information with the new version of the program package, and then transmits the incremental part to the terminal. This requires one more step of network transmission operation, and the workload in comparison and verification is relatively large, and it is not easy to manage;

[0009] 3. In the traditional method, direct or indirect physical connection or network transmission is required for the delivery method of the update package. In the case of weak connection or no connection with the terminal, the package update cannot be performed through the service hosting platform;

[0010] 4. The use of network transmission requires a good network connection as a basis. In the case of low bandwidth or poor network environment, it is very inconvenient to transfer large files
