Abstract
The invention discloses a control method for synchronous time, including the following treatments. A network management launches the operation of synchronous control on opening time; by responding to the operation of synchronous control on the opening time, a network element control system checks whether a network management system mark and the authentication information brought in the operation of the network management system are matched or not; if yes, the following treatment is carried through; the network management system launches the operation of a synchronous control information on a query event; by responding to the operation, the network element management system returns to the synchronous control parameters for the current time; the network management system launches the operation of setting the time synchronous control information and displays the parameters of the time services to the network element management system and asks the network element management system to carry through time synchronization according to the collocated parameters; the network management system launches the operation to set the time synchronous service authentication information and transmits an authentication encrypting cipher code and an authentication key mark to the network element management system.
Description
Technical field
The present invention relates to the communications field, and especially, relate to the time synchronization control method between a kind of network management interface.
Background technology
Interface between network management system (nms) and the Element management system (EMS) is called the Itf-N interface.EMS mainly finishes NE management layer (EML) function among the ITU TMN, promptly finishes the management function of one or more mobile communication equipments, and the EMS between the distinct device supplier can't be general usually.NMS mainly finishes NML (NML) function among the ITU TMN, is responsible for the management of all network elements in the managed network.For the situation that has a plurality of equipment suppliers in the managed network (being called subnet), can reach the purpose of the whole subnet of management by the EMS management.
In the Itf-N interface, some integrated reference point have been defined, as basic configuration management, common configuration management, big data quantity configuration, performance management, alarm management, signatory management, file transfer, link monitoring, notice, access point etc.The functional group that provides by these access points originally can be finished the operation and maintenance function for network.
Real-time Alarm monitoring and the measurement task management in alarm correlation analysis and the performance management at alarm management all have the higher requirement of ratio to the accuracy of time, if and charge and business network on can't debug temporal information, might cause very much losses of revenues and fraud to occur.The clock internal of each independent equipment, computer has all reached than higher precision at present in NMS, EMS and this class management system of service management, but do not have rigorous methods to guarantee that the equipment that disperses can have the unified time benchmark, therefore still wrong or illegal modifications temporal information causes the possibility of serious problems.Network time synchronization agreements such as NTP are set up in the good time synchronization domains at one synchronous mechanism and means are provided, but still lack a kind of settling time synchronized relation to guarantee the whole network time synchronized and sync status controlled method fully.
Therefore, need a kind of new method, be provided at the means of carrying out controlled time synchronized on the network management interface, thereby improve the accuracy of the temporal information of whole system, the possibility of avoiding temporal information to be distorted.

This method may further comprise the steps: first step, network management system are initiated opening time Synchronization Control operation, carry out time synchronized control with the interface of NMS being unified between Element management system to the indication of NE management unit; Second step, network management system are initiated the operation of query time synchronically controlling information; Third step, in response to the operation of query time synchronically controlling information, Element management system returns current time Synchronization Control parameter; And the 4th step, network management system initiates to be provided with time synchronized control information operation, and the parameter to Element management system service instruction time requires Element management system to carry out time synchronized according to configuration parameter.
Wherein, between the first step and second step, may further include following steps: steps A, in response to opening time Synchronization Control operation, in the operation of network element control systems inspection network management system with network management system sign and authentication information whether mate, under the situation of coupling, second step before proceeding to.
Wherein, in steps A, be under the unmatched situation in the Element management system inspection, generate the authentification failure security alarm, and notify other network management system or other management systems.
And, whether in third step, the parameter that Element management system returns comprises: whether possess time synchronized control tenability, current setup time Synchronization Control, time synchronized pattern, time synchronized server location information, synchronous time granularity and the authentication mechanism that whether needs to open NTP.
In addition, the parameter that time synchronized control information operation is set comprises: time synchronized mode parameter, time synchronized server location information parameter, synchronous time granularity parameter and whether needing opened the parameter of the authentication mechanism of NTP.And time synchronized mode parameter express time takes server to the pattern of Element management system broadcasting, the pattern that Element management system is regularly accepted multicast to the pattern or the Element management system joining day synchronization group of server lookup synchronously.In addition, synchronous time granularity parametric representation is adopting the Element management system timing under the situation of the pattern of server lookup, the Element management system time interval regularly.
Wherein, time synchronized server location information parameter is the IP address at ntp server place.
In addition, whether the parametric representation that whether needs to open the authentication mechanism of NTP needs to use the security mechanism of NTP, wherein, uses at needs under the situation of security mechanism of NTP, uses authentication information in the message transmission of Element management system and time synchronized server.
And, use at needs under the situation of security mechanism of NTP, further may further comprise the steps: the 5th step: network management system initiates to be provided with the operation of time synchronized server authentication information, transmits authentication ciphering key, KI sign to Element management system.
Pass through technique scheme, the present invention can improve the accuracy of temporal information in network management system and the Element management system, reinforcement is to the control ability of time synchronized in the whole system, and the possibility of avoiding temporal information to be distorted, make things convenient for the centralization to Element management system, the realization of automatic management, improved the efficiency of management.
