Description

Authorization method for controlling multiple devices, communication device and server
Technical Field
The present invention relates to authorization (License) technologies, and in particular, to an authorization method, a communication device, and a server for controlling multiple devices.
Background
With the diversification development of telecommunication services, the software and hardware integration and complexity of telecommunication equipment are increasing day by day, and the cost and price of the telecommunication equipment are also increasing. In order to reduce the early investment of telecommunication operators, the telecommunication equipment suppliers adopt License technology to carry out soft control on the functions, the capacity, the use time and the like of the sold telecommunication equipment. Thus, the telecom operator only needs to purchase the telecom equipment supporting part of the functions and capacity at the beginning according to the needs. When the market of the carrier is mature or expanded, the telecom carrier can purchase License files from the telecom equipment supplier to expand the functions and the capacity of the telecom equipment.
Currently available License control schemes can be divided into: a stand-alone License control scheme and a network License control scheme.
The single License control scheme refers to: setting a License file for each device, binding each License file with the corresponding device identification information, and controlling the permitted use of the device.
The network License control scheme refers to: the licensed use of all devices within the network is controlled by a License Server (Server). The License file corresponding to each device is stored on a License server, the License file does not need to be loaded on each device in the network, and the device requests permission through communication with a License server.
In the License control scheme in the prior art, the form and format of the License file are different, and the common License file adopts an initialization (INI) format or an extensible markup language (XML) format. The License file in the INI format is in the form as follows:
ESN=“13612345678”;
Resource=“MaxUser=200000”;
Sign=00DA7462150D36C6909B6D56828EB9C6E323D40;
the device identification information (ESN) field in the License file specifies that the identification information of the device authorized to use the License file is 13612345678; the Resource field specifies that the capability control information supported by the License file is: the maximum number of equipment runs is 20000; the Sign field is a signature field of the License file, and the signature field gives a validity verification condition of the whole License file.
When the license control scheme in the prior art is adopted to control the permission of the use of a plurality of devices, one mode is as follows: setting a License file for each device, wherein the License file only contains identification information of the corresponding device; the other mode is as follows: setting the same License file for a plurality of devices, and enumerating the identification information of the corresponding devices one by one in an ESN field in the License file.
When the number of devices is large, the License file is set for the devices by using the first implementation manner, and an operator needs to load the License file set for each device by a device provider onto the corresponding device, that is, different devices need to receive different License files issued by the device provider, when the number of devices is large, that is, the number of License files is large, the device authorization process is complicated, and a situation that the License files do not correspond to the devices is easy to occur, that is, loading errors is easy to occur, so that device authorization fails. Meanwhile, the device supplier needs to set a License file for each device, and when the number of devices to be set is large, the setting workload of the authorization file is large.
When the License file is set for the device by adopting the second implementation manner, although the number of License files set by a device supplier can be reduced, the License files are huge because the device serial numbers are enumerated in the same License file one by one, and the current device needs to compare the device identification with a large number of device serial numbers one by one in the actual device authorization process, so that the device authorization process becomes complicated, and the problem of large workload still exists.
