The technology can be used as a wireless DSL, Tl, and Cellular alternative to address the Last Mile wireless broadband access problem. Compared with other technologies, WiMAX has the following advantages: It adopts IP communication protocol and is easy to integrate with other IP networks. It has high transmission rate and QoS mechanism, and can provide high-quality voice and multimedia services. It has a long transmission distance and can cover a wide range of areas. , reduce construction costs; high data transmission rate, can serve more users; complete security mechanism to ensure data security; because the technology is wireless transmission technology, it can reduce wiring costs. In order to support the mobile features, new features such as handover, QoS, and security are added to the IEEE802.16d for portable and mobile scenarios, and fixed scenarios are also supported. Mobile data services are the main applications of mobile scenarios, including At present, it is widely regarded by the industry as mobile E-mail, mobile IPTV, mobile phone, mobile game, mobile VoIP, etc., and these services are also occupying more wireless resources. At present, the software architecture of the WiMAX wireless network card basically adopts the scheme shown in FIG. As shown in Figure 1, the architecture of the WiMAX wireless network card can be mainly divided into two parts: host side software and device side software. Host-side software includes user software (or GUI or Connection Manager), device Common API, and driver; device-side software is mainly firmware, which is used to implement the functions defined by the IEEE802.16e protocol, and a specific interface (USB). /PCMCIA/Express, etc.) drive function, chip start boot function, firmware download function, etc. In addition, in order to save storage space, the non-volatile memory in this scheme uses an electrically erasable programmable memory (EEPROM) scheme instead of FLASH, and the firmware is not stored in the EEPROM on the device side. Instead, it is stored somewhere on the host. Whenever a WiMAX wireless network card is inserted into the host, the operating system in the host will force the corresponding driver, and the driver will automatically download the firmware to the RAM of the WiMAX wireless network card. When the NIC is removed, the firmware in RAM will automatically disappear. The next time you plug in the device, the driver will automatically download the firmware to the RAM of the WiMAX wireless network card. For the software solution of the wireless network card device, how to better perform remote management, maintenance and upgrade of the device software (including the host side software and the device side software) is a new problem to be faced. As is well known, many mobile terminals have adopted the OTA method for remote upgrade of software, for example, the Open Mobile Alliance (OMA). Due to the limited storage space of the mobile terminal itself, most of the upgrade schemes use complex algorithms (for example, differential technology) to ensure software upgrade reliability in the case of limited storage space.

DETAILED DESCRIPTION In this embodiment, a method for updating a network card of a WiMAX system is provided. This method can Apply OMA protocol updates (eg, upgrades) to the WiMAX wireless network card on the host. Before describing the method, the system architecture that implements the method is first described. As shown in Figure 2, the WiMAX network card upgrade system consists of the following components: Open Mobile Alliance Device Management Server (OMA DM Server), Wimax Wireless Network Card, host (as shown in Figure 2, for example, can be a computer) side software. The OMA DM Server maintains up-to-date and relevant information and is responsible for initiating and managing the entire upgrade process. The WiMAX wireless network card is a hardware device that implements the physical layer and the MAC layer of the Wimax protocol, and the entire upgrade process is transparent to the Wimax wireless network card. The host side software is composed of user software, a device common application interface (Common API), and a driver. The user software provides a user-friendly interface, and converts the user-related operations of the interface into corresponding control commands, and drives the WiMAX wireless network card to complete the corresponding Function; driver WiMAX wireless network card hardware interface and WiMAX chip; device API provides user software with interface to control and manage WiMAX wireless network card, and OMA DM client (Client) is one of the modules used to cooperate with OMA DM Server Updates to WiMAX wireless network cards (including host side software and device side software for network cards). In view of the special operation mode in which the WiMAX wireless network card is closely related to the host, the present invention proposes to package the network card driver, the device API, and the Connection Manager (CM) that need to be upgraded into an installation package of Microsoft Installation (MSI) format. The MSI installation package is first downloaded from the OMA DM Server to the host through the OMA DM Client, and then the CM is notified and the user selects whether to immediately run the MSI to perform the PC side software update operation. This type of NIC upgrade is divided into two main phases: (1) Download: The MSI installation package is completely downloaded to the host through the OMA DM Client; (2) Update: initiated by the CM, by running the MSI installation package, using each The new version of the module replaces the old version. The embodiment will be described in detail below with reference to the drawings. As shown in FIG. 3, the method for updating a WiMAX system network card according to this embodiment includes: a step S302, encapsulating a new version of related information into an installation package (MSI format), and storing the installation package in the DM Server (ie, the above On the OMA DM Server, in step S304, the DM client of the host performs a DM session with the DM server; Step S306, in the case that it is determined that the new version needs to be downloaded through the DM session, the DM client requests to obtain the location address of the installation package, and The installation package is downloaded to the host according to the obtained location address. After the download is complete, the DM client sends a report message to the CM, where the report message carries at least one of the following: location information of the installation package in the host, and name information of the installation package. In addition, in the case that the update is required, the method further includes: Step S308: After the download is completed, the DM client updates by using the downloaded installation package. The step S308 is specifically as follows: The CM notifies the DM client to start the update; the DM client closes the CM, and then updates. And, after the updating, further comprising: starting the closed CM. In addition, the contents of the above installation package include: driver, device application program interface (API), and firmware. In addition, in the case that the host loses power during the process of downloading the installation package, the host resumes the breakpoint on the basis of the previous download when the power is turned on again. As shown in FIG. 4, in an actual application, the updating method according to an embodiment of the present invention may include the following steps:

(1) The device manufacturer makes the new version of the driver, device API and firmware into an MSI installation package and places it on the OMA DMS Server;
