Problems solved by technology

Therefore, if when the network is busy, there is a delay of 0.5 seconds between the time server sending the time message and the time message being received by a host on the network, then the time synchronization error between them is 0.5 seconds. It is intolerable in a distributed system with strict synchronization time error requirements
[0026] 2. Low accuracy
Therefore, if the time of the time server itself is inaccurate, it will lead to inaccurate time of t

Embodiment Construction

[0071] The invention provides a method for obtaining current system time in WiMAX equipment. The core of the present invention is: by setting a time server in the WiMAX device, and then the client of the WiMAX device and the time server exchange message packets with time stamps to obtain the current system time with a certain accuracy.

[0072] Describe the present invention in detail below in conjunction with accompanying drawing, the specific processing flow of the method of the present invention is as follows figure 1 shown. Including the following steps:

[0073] Step 1-1. Set a time server in the WiMAX device.

[0074] The present invention first needs to set a Time of Day Server (time server) in the WiMAX equipment. Then connect the time server to the internet network. The WiMAX device will obtain the current system time through the time server.

[0075] Step 1-2, the time server realizes synchronization with the standard time through the internet network.

Abstract

A method to get the current system time in the global interaction microwave access equipment, includes: sets the time server in the global interaction microwave access MiMAX equipment; the guest room end of the WiMAX equipment sends the information package with the time stamp to the time server; the WiMAX equipment get the current time according to the information package with the time stamp from the time server. The invention can get the more accurate current system time of the user's station and the base station of the WiMAX equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for obtaining current system time in a global interactive microwave access device. Background technique [0002] As important basic physical quantities, time and frequency play an important role in national economy, national defense construction and basic scientific research. Time and frequency are reciprocals of each other, and the measurement benchmark of Chinese time and frequency is preserved in the National Institute of Metrology of China. [0003] The development of the Internet (Internet) has made electronic money, online shopping, online securities, and financial transactions possible. Customers can sit at home and use personal computers to carry out the above activities. To ensure the normal progress of these activities, there must be a unified time. [0004] Many hosts on the network do not have the concept of time, and the time of the hosts can often be changed art...
