Problems solved by technology

For data transmission and system update of embedded (embedded) devices, it is more often necessary to take cumbersome synchronous update steps (such as synchronous online transmission between a personal computer and a pocket computer (Pocket PC)), etc., which are not fully utilized. Advantages of network transmission
The transmission and release of data often needs to ensure security certification, often requiring users to enter user names and passwords, etc., which is complicated, and sometimes data transmission cannot be guaranteed to be safe and effective

Embodiment Construction

[0023] The Session Initiation Protocol (SIP) is a protocol belonging to the Application Layer (Application Layer) of the Open Systems Interface OSI (Open Systems Interconnection), and serves as a control protocol for initiating, maintaining, and ending a session. SIP adopts a protocol similar to Hyper Text Transfer Protocol (HTTP) and uses a master / slave (client / server) structure. In terms of packet processing, SIP can also use the existing packet data of HTTP. Therefore, SIP is a very suitable transmission structure for the Internet. Based on this advantage, the present invention utilizes the SIP protocol to update the system of the communication device.

[0024] Fig. 1 is a block concept diagram of the embodiment of the present invention, the communication device 100 obtains the Internet address (Internet Protocol Address, IP address) 120 through the channel (Gateway) 110 of the session initiation protocol, and by this Internet address 120, the communication device 100 The c...

Abstract

The network apparatus uses SIP (session initiation protocol) to locally update the software for the system. The users have no need to input the user name and password to log in the SIP server. Using the SIP to make authentication can let the network apparatus easily log in the server and can be used for encrypting data in order to ensure the safety of data.

Description

technical field [0001] The present invention relates to a system updating method of a network device, in particular to a system updating method of a network telephone using the Session Initiation Protocol (Session Initiation Protocol, SIP). Background technique [0002] Most of the updates of current system software, patches or installation programs are downloaded to the user's location by using the Internet, and then downloaded locally, such as Microsoft's window update (Windows Update); To complete the system update, so the application field and scope are very narrow. For data transmission and system update of embedded (embedded) devices, it is more often necessary to take cumbersome synchronous update steps (such as synchronous online transmission between a personal computer and a pocket computer (Pocket PC)), etc., which are not fully utilized. Advantages of network transmission. The transmission and release of data often requires security certification, and users are ...
