Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] attached figure 1 It is the OMA DM framework applied by the embodiment of the present invention.

[0042] Wherein, a DM agent (DM Agent) 101 on the terminal device 100 is used to interpret and execute management commands issued by the DM server. The management tree 102 stored on the terminal device can be considered as an interface for the DM Server200 to manage the terminal device through the DM protocol, including some basic management objects (Management Object, MO); The management object is operated, so as to achieve the purpose of controlling the terminal management object. Operation commands include acquisition (Get), replacement (Replace), execution (Exec), replication (Copy), deletion (Delete), etc.

[0043] The DM management tree and management objects are composed of nodes, such as root nodes, internal nodes and leaf nodes. Nodes ha...

Abstract

The invention discloses a transmission method of a large data object, comprising the following steps: transmitting a large data object to a receiving device by a transmission device in a block way inthe device management session process; when the transmission process is interrupted, reinitiating a session process; and judging whether the large data object changes or not before and after interruption, if no changes, and transmitting residual data of the large data object to the receiving device by the transmission device according to the length of the received data recorded in the receiving device. By implementing the embodiment, large data interrupted in the transmission process are continuously transmitted in the data synchronization (DS) session process, thereby saving wireless resources and reducing the flow rate.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a transmission method, a transmission system, a sending device, and a receiving device of a large data object. Background technique [0002] DM (Device Management, device management) V1.2 (hereinafter referred to as the DM specification) of the Open Mobile Alliance (Open Mobile Alliance, OMA) is a unified specification for device management formulated by the OMA DM Working Group (WG). The DM system provides a low-cost solution for third parties to manage and set the environment and configuration information in wireless network terminal devices (such as mobile terminals and functional objects in terminals), and solve the problems encountered in the use of these network devices. The problem is to perform software and firmware installation, upgrade and other operations through the wireless network (over the air, OTA), and provide more humanized and personalized ser...
