Embodiment Construction

[0022] The invention provides a clock synchronization method of a CDMA base station network management system.

[0023] The OMC network management system includes NMC and OMM. The synchronization method provided by the system is to obtain GPS time from the CDMA base station, and then synchronize to the background OMM. The NMC server synchronizes with the OMM, and the clients of other OMMs and NMCs synchronize with their servers, so as to achieve the purpose of synchronizing all clocks in the OMC system.

[0024] The method of the present invention includes the following processes:

[0025] In the first step, the user configures clock source information on the NMC user interface.

[0026] In the second step, the NMC synchronizes with the clock source OMM, and the clock source OMM starts a synchronization program with the foreground NE, and constructs an internal message with a time stamp to the foreground NE.

[0027] Step 3: The foreground NE receives the message, fills in ...

Abstract

The invention relates to a clock synchronization method of a CDMA base station network management system, which consists of the following steps: a first step is to choose a district-level management center as a clock source, which is used by the network management center to select a base clock source or a user configuration synchronic with a network management system, as a district-level management center acting as a clock source; a second step is to synchronize the GPS time of the district-level management center with that of a CDMA base station, which is used to determine the time of the clock source; a third step is to synchronize above network management center with other district-level management centers beside the above district-lever management, which is use for time synchronization among the network managements. In the invention, by completing the synchronization of the received GPS time of the CDMA base station, a user can switch among different base stations via a user interface, and the synchronization of the whole OMC network management system is achieved, and the deviation of OMC time from normal time and the time inconsistency between OCMs have been resolved, and the precision and the accuracy of the OCM network system clock has been promoted.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a clock synchronization method for a network management system of a CDMA base station. Background technique [0002] When the operation and maintenance center (OMC) network management system is used to manage and maintain the CDMA base stations, since the base stations managed by each district-level management center (Operation Maintenance, OMM) are limited, there are often multiple OMMs in the network management system. There is no method for clock synchronization, and the times of OMMs are often inconsistent. When time-related information such as performance collection data (including data collection time) is displayed in the network management center (NMC), these inconsistent time information may cause the bureau to obtain wrong analysis results when analyzing performance data. Since all OMM routes are not interconnected, it is difficult to achieve the purpose ...
