Description

Method, server and system for downloading and installing upgrade package

The present invention relates to the field of mobile communication technologies, and in particular, to a method, a server, and a system for downloading and installing an upgrade package based on an OMA DM (Open Mobile Alliance Device Management) protocol. Background technique

At present, with the rapid development of mobile communication technologies, 3G (3rd-generation, third-generation mobile communication technology) and more powerful mobile communication systems are gradually being applied to people's lives and work. As a new generation of terminal device management protocol, OMA DM is increasingly used in various types of terminal devices, including device activation number/parameter collection/device configuration. In particular, OMA DM-based terminal firmware upgrade (FOTA, Firmware Update Over The Air) technology has gradually become the mainstream after-sales upgrade technology selected by operators. The technology has many advantages such as providing online upgrade capabilities for various terminals, improving the user experience, repairing software failures, reducing the operation and maintenance overhead of operators to recall faulty devices, and providing continuous value-added services to terminals.

However, as the frequency of terminal version upgrades increases and the differences between versions increase, the size of the upgrade package for fault repair and the upgrade package for operators to promote new services are gradually increasing, increasing from several hundred K. To several megabytes, even dozens of megabytes. Therefore, it challenges the DM (Device Mangement) server and client, especially the ability of the client to support the upgrade of the terminal product. For example, Verizon has proposed to support under LTE (Long Term Evolution). 150M big package upgrade requirements.

However, existing clients usually do not have the ability to optimize network downloads, but use 2G/3G network downloads. Not only are download speeds slow, but also fault tolerance and concurrency performance are poor, and even large upgrade packages cannot be downloaded, resulting in poor user experience. . Therefore, the client needs to increase the support of other non-2G/3G download modes. However, the user only selects the access mode to satisfy the scenario where the server address does not change under various access networks, and cannot adapt to the change of the server address. . In fact, due to various forms of access networks, the addresses of servers and reporting servers may be different, such as downloads under LTE/wired networks. The address of the server is usually different from the address of the preset server account, so it is necessary to add new servers and clients. Negotiation mechanism.

In addition, due to the limited FLASH resources of the terminal, the space reserved for storing the upgrade package is not sufficient, and the requirements for the network and storage space of the large upgrade package cannot be met. When downloading a large upgrade package, some clients check whether the size of the upgrade package can be stored. If the size exceeds the size, the download is refused, which directly leads to the upgrade download failure, and the support for the large package upgrade is poor; or some clients regardless of the upgrade package How much of the download process is performed, which eventually leads to the failure of the download and installation, which not only wastes bandwidth resources but also affects the user experience.

In summary, the current standard firmware upgrade method based on the OMA DM protocol has the following defects in the face of large upgrade package download and installation requirements:

(1) The large upgrade package is downloaded from 2G/3G network. The download speed is low and the user experience is poor. However, the current OMA DM protocol lacks the mechanism to support the optimal non-2G/3G download upgrade package, which cannot be downloaded for the large upgrade package. Faster network selection;

(2) The current OMA DM protocol lacks support for downloading and installing large upgrade packages. It cannot guarantee the storage space negotiation, network retry time, and download under the life cycle of large packages. Summary of the invention

The solution of the embodiment of the present invention is as follows: The server obtains the storage space information available to the current upgrade package of the client, and negotiates with the client to adapt the storage space resource. After the negotiation succeeds, the server sends the pre-configured download parameter set to the client. The client initiates an upgrade package download and installation process according to the download parameter set, so as to improve the download speed of the large upgrade package and improve the user experience.

The embodiment of the present invention is applicable to a mobile terminal deployed with an OMA DM protocol client, but is not limited thereto, and is applicable to a data card having the same condition and a single mode/dual mode terminal device such as modern.

As shown in FIG. 1, an embodiment of the present invention provides a method for downloading and installing an upgrade package, including:

Step S101: The server obtains the storage space information available for the current upgrade package of the client. When the upgrade package needs to be downloaded and installed on the client, the server queries the client for the storage space information of the current upgrade package of the terminal where the client is located.

Specifically, the server and the client exchange commands through the OMA DM protocol, and the server sends a standard OMA DM Push message to the client to trigger an upgrade, and then the server performs a standard OMA DM Pkgl and Pkg2 interaction with the client, and the client The server sends basic object information.

The server sends an OMA DM Get query command to the client. After receiving the query command sent by the server, the client returns the storage space information of the upgrade package currently available to the server to the server.

Step S102: The storage space resource is negotiated with the client according to the storage space information. The server negotiates the storage space resource with the client according to the storage space information returned by the client. Specifically, the server stores the available storage package of the client. Space and current upgrade package If the size of the current update package is larger than the current upgrade package, the client currently has the storage space for the upgrade package to download. The negotiation is successful.

If the storage space available for the current upgrade package of the client is smaller than the current upgrade package, the storage space of the current upgrade package of the client is insufficient. The server sends a memory cleanup and resource preparation command to the client. In this embodiment, the server sends the memory to the client. The exec pre-defined memory cleaning node is described as an example, but it should be understood that other OMA DM command operations that can implement similar cleanup notifications are not limited herein. After receiving the memory cleanup and resource preparation commands sent by the server, the client performs memory cleanup and prepares the required upgrade package storage space.

The above memory cleaning includes but is not limited to deleting redundant files or checking the peripheral T card (T-Flash card) space available resource recovery and expansion operations. For example, if the storage space is still insufficient after the client is cleaned by memory, check if there is available external storage space, such as T card space. After the memory is cleaned up and the resources are prepared, if the client's storage space is sufficient, the client reports that the cleaning is successful. Otherwise, the cleaning fails.

The client returns the result of the cleaning to the server. The server determines the result based on the cleaning result. If the cleaning result indicates that the current storage space of the client is greater than the current upgrade package, the client currently has the storage space for the upgrade package to download. The negotiation succeeds. Otherwise, the negotiation is performed. failure.

Step S103: After the negotiation succeeds, the pre-configured non-2G/3G network download parameter set is sent to the client; the client initiates the download and installation process of the upgrade package under the non-2G/3G network according to the download parameter set.

After the negotiation is successful, the server sends the non- 2G/3G network download parameter set required by the current upgrade package to the client.

The download parameter set includes but is not limited to the following: an upgrade package life cycle, a network preference type, a corresponding network type server URL (Uniform I Universal Resource Locator, a uniform resource locator, also referred to as a web address), and an upgrade result reporting server URL. The upgrade package download parameter OMA DM object definition example is shown in Table 1. Table 1 Download parameter OMA DM object definition example

After that, the client selects the appropriate non-2G/3G network to initiate the upgrade package download according to the download parameters configured by the server, and manages the download and installation process of the upgrade package according to the configured parameters, and downloads the upgrade package to the local, and then correctly installs and upgrades.

Among them, non-2G/3G networks may include but are not limited to WiFi (wireless fidelity), LTE, Bluetooth or wired networks.

As shown in FIG. 2, the foregoing step S101 includes:

Step S1011: The server sends a query command to the client.

Step S1012: Receive storage space information available to the current upgrade package returned by the client according to the query command.

As shown in FIG. 3, the foregoing step S102 includes:

Step S1021, the server compares the available storage space of the current upgrade package and the size of the current upgrade package; if the available storage space of the current upgrade package is larger than the current upgrade package size, the process proceeds to step S1025; otherwise, the process proceeds to step S1022;

Step S1022: The server sends a memory cleanup command to the client.

Step S1023, receiving the memory cleaning result returned by the client according to the memory cleaning command; if the cleaning result indicates that the current storage space of the client is greater than the current upgrade package, proceeding to step S1025; otherwise, proceeding to step S1024; Step S 1024, the negotiation fails.

In step S1025, the negotiation is successful.
