Embodiment Construction

[0031] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] figure 1 It is a structural diagram of the present invention. The scheme described in the present invention can be applied in the third generation mobile communication system, mainly based on the following premise: one is that accurate time information can be obtained through the NTP Server; the other is that the equipment where the NTP Server is located and other There is a direct Ethernet connection or an IPOA (IPOver ATM) connection between devices such as RNC, NodeB, and BTS.

[0033] Establish NTP Server as the reference time server in the system to provide time services to other node devices or network element devices that require time synchronization, and set each node device or network element device in the system network to a configurable time synchronization mode.

[0034] The time server can be provide...

Abstract

The invention discloses a method for time synchronization in a third generation mobile communication system, establishing NTP server as the benchmark time server in the system, providing time serviceto other node equipment or network element equipment with time synchronization requirements and setting each node equipment or network element equipment in the system network as configurable time synchronization mode. Each node device or network element device in the system network sets the IP address and port number of the NTP server it depends on through configuration management, and obtains thetime synchronization service from the NTP server. The method can realize the whole time synchronization network configuration and operation within the 3G system, and can realize the multi-vendor equipment sharing of the NTP service, so as to enhance the convenience of the multi-vendor interconnection.

Description

technical field [0001] The present invention relates to the problem of time synchronization in mobile communication systems, in particular to wideband code division multiple access (WCDMA) systems, TD-SCDMA communication systems and between network elements, between network elements and network element management systems and other network nodes in CDMA2000 systems method of time synchronization. Background technique [0002] With the development of wireless communication technology, the communication network is becoming more and more complex and huge, which further increases the difficulty of how each node in the network obtains accurate time. Accurate time information in the third generation mobile communication network plays an important role in the services provided by the network. The main time synchronization requirements come from several aspects: [0003] 1) The alarms and logs of the network management system need to accurately record the exact time of events and a...
