Embodiment Construction

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] As mentioned above, the FOTA technical specification following the OMA protocol is mature, it does not depend on the network type, and can be widely used in mobile communication networks such as CDMA / GSM / 3G / PHS / WiMAX. At the same time, because the FOTA technology provides functions such as breakpoint resume transmission, service priority setting, and data verification, it can ensure the efficiency and continuity of firmware downloading. For this reason, the present invention provides a mobile terminal remote firmware upgrade technology based on FOTA technology.

Abstract

The invention discloses a remote firmware upgrading method and the system of mobile terminal, wherein, the upgrading method comprises the following process: the application server prepares and downloads the pending firmware package to the OMADM server; the OMADM server establishes connection with the mobile terminal and downloads the firmware package to the mobile terminal. The upgrading system comprises an OMA DM server. The invention can realize the remote firmware upgrading of mobile terminal with the FOTA technique without influencing the normal business of the customers, and can guarantee the efficiency and continuity of the firmware downloading. Through executing the backing operation, the invention guarantees the security and reliability of the firmware upgrading in the condition that the firmware upgrade is failed. The invention has the advantages of general applicability, low cost of network reform and high utilization ratio of signal channel.

Description

technical field [0001] The present invention relates to a firmware over the air technology (Firmware Over The Air, FOTA for short) in the communication field, and in particular, relates to a method and system for remote firmware upgrade of a mobile terminal based on the OMA DM (Device Management, device management) protocol. Background technique [0002] With the development of mobile communications, mobile terminals such as mobile phones and personal digital assistants (PDAs) no longer serve as simple communication tools. On the contrary, they integrate multimedia functions, personal information management functions, and entertainment functions. Gradually evolved into a "handheld computer." [0003] At the same time, complex functions inevitably require complex software design. In other words, maintenance and firmware upgrades of mobile terminals usually need to be completed by manufacturers or service providers. Taking a mobile phone as an example, during the user's use, ...
