Embodiment Construction

[0037] The present invention adds SNTP service or customer process in network element equipment and / network management equipment, and the time synchronization operation based on SNTP agreement is completed by these processes, and because the interface between these equipments all adopts IUB interface, therefore also eliminates the interface different band There is a problem with the coming interface docking.

[0038] like figure 2 As shown, it is a schematic diagram of the network element structure using the network time synchronization method based on the simple network time synchronization protocol in the present invention, wherein the SNTP service process is started in the process of the network management server 1, and the network management server 1 can simultaneously perform time synchronization to the upper layer server . The background management module 2 and the foreground management module 3 on the wireless network controller 4 start the SNTP service process and / or...

Abstract

This invention relates to a network time synchronous method based on SNTP including: the BAM of RNC starts up a first SNTP service process and the FAM of the RNC starts up a first SNTP customer process, which sends a request for checking the time to the first service process, which sends its own time parameters to the first customer process to judge if the difference of the received time parameter and the local time parameter surpasses a preset threshold, if so, it sets the received time parameter as the local parameter, which starts up the service and customer process of the SNTP and finishes the time synchronous operation based on the SNTP protocol and synchronous time parameters are kept among NE and NE and network management to secure the accuracy of the statistic to its performance.

Description

technical field [0001] The present invention relates to a method for maintaining and managing network elements in a Universal Terrestrial Radio Access Network (UTRAN for short), in particular to a simple network time synchronization protocol (SNTP for short) to monitor the network elements in the UTRAN network. A method for synchronizing network time between network elements and network management equipment. Background technique [0002] Accurate time information in the network plays a very important role in the services provided by the network. The communication network and its nodes often need to be synchronized in order to schedule and execute processing tasks in an orderly manner to avoid errors in communication and / or task execution. conflict. With the development of wireless communication technology, the communication network is becoming more and more complex and huge, which brings great difficulties to each node in the network to obtain accurate time. The third-gene...
