A2), from security standpoint, in the process that network element NodeB and Element management system EMS establish a communications link, can comprise processes such as login, authentication, encryption.That is, network element NodeB uses default login username and login password login Element management system EMS, and Element management system EMS carries out authentication to this login user, to determine that accepting this network element NodeB inserts.In addition, can arrange cryptographic algorithm in advance, the data that data transmission procedure between network element NodeB and the Element management system EMS relates to are encrypted by network element NodeB and Element management system EMS.
In this step, network element NodeB is by reading the user profile of local storage, obtain default information such as Element management system IP address, FTP port, FTP user's name and ftp password, together with information such as the ID of this network element, NE types, form message body, encrypt the message body of back as SOCKET message.After network element NodeB and Element management system EMS set up TCP/IP and be connected, network element NodeB sent this SOCKET message to Element management system EMS, and the type of message of this SOCKET message is NETWORKELEMENT_AUTOLOGON;
Wherein, FTP (File Transfer Protocol) is a file transfer protocol (FTP), and ID (Identity) is sign, OMC (Operation﹠amp; Maintenance Center) be operation and maintenance center, TCP/IP (Transmission Control Protocol/Internet Protocol) is a TCP.
B1), whether Element management system EMS can determine to allow network element NodeB to insert behind the notification message of receiving network element NodeB;
B2), Element management system EMS obtains element configuration data and can pass through FTP or other modes.
In this step, after the notified message of Element management system EMS,, select manner of decryption that message body is decrypted according to the type of message, according to the FTP port in the message body, FTP user's name and ftp password information, under network element FTP catalogue, obtain the corresponding net element configuration data file again.
C1), the file format that the element configuration data of NodeB uses can be the form that Element management system EMS and network element NodeB arrange in advance, also can use the form (as the XML form) of standard;
Wherein, XML (eXtensible Markup Language) but be the extension flag language.
C2), Element management system EMS after finishing configuration data conversion, the internal configurations of stress living data.Promptly these internal configurations data are not only and are stored in statically in the database, also should be related with relevant resource dynamic in the Element management system EMS, and be presented on the user interface.
In this step, Element management system EMS is the element configuration data file conversion that gets access to the inside autoexec of Element management system EMS according to prior appointed file form.Element management system EMS generates the internal configurations data after carrying out this autoexec, and deposits database in.
In this step, Element management system EMS initiates the application layer handshake procedure according to information such as the NE type of network element NodeB and network element IDs to network element NodeB.
After finishing this step, Element management system EMS should be able to carry out normal maintenance and management operation to network element NodeB.
How the invention solves Element management system finds network element automatically and realizes the problem of configuration automatically, realize that Element management system is under the situation without any element configuration data, make network element after powering up, can insert automatically and configuration data is transferred to Element management system, realize normally open-minded to network element.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
