Description

How to secure reliability using heartbeats in the interworking between EN and MD in T & M

The present invention relates to the prevention of connection short circuit and data transmission error when data is transmitted between a network element (NE) and a media device (MD) in a telecommunication managed network (TMN), and a heartbeat between a MD and a base station manager (BSM) is provided. A method of increasing the reliability of data transmitted and received by periodically transmitting a data packet is provided.

The conventional base station management system is configured as an independent workstation system, performing the operation and maintenance functions of several base station controllers and base stations.

Since several base station management systems are operated in each region, the actual network management center is operated in conjunction with many regional subsystems, and BSS (Base Station Subsytem) data is transmitted through TCP (Transmission Control Protocol) / IP (Internet Protocol). It is transmitted using the socket application of.

As is well known to those skilled in the art, TCP is the Transmission Control Protocol, a communications software developed by the US Department of Defense, used in heterogeneous computer networks, to support the transport layer.

In the TCP / IP socket communication used when the network management center and the BSS interoperate with each other, data loss occurs when the communication is suspended due to external causes.

At this point, there was no better way to know exactly what was missing. Therefore, in order to restore lost data, it is necessary to restore the data from an uncertain loss point, thereby increasing the load of the application and processing time.

Accordingly, in order to solve the above problems, the present invention periodically transmits heartbeat data to minimize data loss due to transmission failure in collecting data for management of the network management center and each local system. By providing a TCP / IP communication method, an object of the present invention is to increase the reliability of data transmitted and received through accurate transmission of data.

One preferred embodiment of the use of the heartbeat to secure the reliability in the interworking between the NE and MD in the TMN according to the present invention for achieving the above object,

The heartbeat data packet is periodically transmitted between the media device (MD) and the base station manager (BSM) to improve the reliability of data transmitted and received.

In the present invention, the heartbeat packet is

4 bits of sequential numerical information;

4 bits of length information; 4 bits of instruction information;

100 bit file name information; And

It is preferable to include 4bit file point information,

The connection procedure between the network management center and the BSS is

A first step of establishing a connection;

A second step of sending a message;

A third step of suspending message transmission;

A fourth step of resuming message transmission;

A fifth step of checking a connection state;

Remote Man Machine Language (MML) and

A sixth step of delivering the result; And a seventh step of releasing the connection,

In the first step, when it is determined that the initial and system initialization is necessary, null is transmitted from the MD (Mediation Device) to the BSM (Base Station Manager) side, and otherwise, the MD requests a heart when requesting connection establishment. It is preferable to use the method of using heartbeat that the file name field is filled and transmitted using the information provided in the bit exchange procedure, and the received BSM transmits the file from the corresponding file to the MD side.

In the fifth step, the heartbeat is transmitted to the BSM side by one minute and the response to the heartbeat is waited until one minute, which is a transmission cycle.If there is no response, the MD closes the socket and the administrator knows and takes action. In this case, the BSM preferably uses the method of using the heartbeat that transmits the heartbeat response (HeartBeatAck) and the name of the file and the pointer of the file being transmitted in response to the heartbeat.

When the MD sends a heartbeat control command to the BSM during the connection check phase, the BSM receives the heartbeat response and uses the file name packet to fill and transmit the file and file point currently being transmitted. Preference is given to using the method.

Referring to the configuration of the present invention with reference to Figure 1,

The data to be sent and processed from the BSM

Alarm and Disability

Status and shape information

Long-term statistics (15 minutes, one hour)

MML (Man Machine Language) from MD to BSM and its consequences

-Statistics not sent.

Data ports for transmitting the above data are shown in FIG.

Here each 5 port uses all heartbeats.

Among the 'ALM_FLT_PORT' dedicated ports, only messages with Axxxx, Fxxxx of Message ID (Identification) are transmitted among Message History Data (MHD). Where A and F are alphabetic characters and xxxx is a decimal number.

As a dedicated port of 'STATUS_PORT', the result file of Sxxxx, Mxxxx and MML used in the MHD, and the request result MML from the MD are transferred (change shape information file).

The 15-minute and 60-minute statistics are sent to the 'LONG_STAT_PORT' dedicated port.

The result of MML requested by MD is transmitted to 'MMC_PORT' dedicated port.

The 'BACKUP_PORT' dedicated port transmits 60-minute statistics (files that are packed in 60-minute increments in 15-minute increments) to ensure reliability for 15-minute files that may have been lost if an error occurs in the dedicated port.

The configuration of the heartbeat packet with reference to Figure 2,

'Sequential number' is a field that is filled in and transmitted from the MD side. In the BSM, the received sequential number is filled in as a response without any change.

'Length' is the sum of all five fields.

'Command' is a field for a control command of a procedure using a heartbeat packet.

The procedures using the heartbeat packet are the connection establishment procedure and the connection status checking procedure.

In the case of the connection establishment procedure, the 'file name' is filled with nulls from the MD to the BSM when it is determined that initial and system initialization is required. Otherwise, the MD fills in the file name field using the information provided in the heartbeat exchange procedure and requests the connection establishment. The received BMS transmits the file to the MD.

In the case of the connection status checking procedure, when the MD sends a heartbeat control command to the BSM, the BSM receives the heartbeat response ('HeartBeatAck') and fills the file and file point currently being transmitted.

'File Point' represents a pointer of the file currently being transmitted by the BSM.

The procedure for establishing a connection between the network management center and the BSS is as follows.

Connection setup procedure

Message sending procedure

Message suspension process

-Message transmission resume procedure

-Connection check procedure

Remote MML and Results Delivery Procedures

The connection release procedure, and among these procedures, the procedure of using the heartbeat packet of the present invention is a connection establishment procedure and a connection state checking procedure.

Here, the connection establishment procedure will be described. When it is determined that the initial and system initialization is necessary, the MD is transmitted to the BSM side with a null. Otherwise, the MD fills in the file name field using the information provided in the heartbeat exchange procedure and requests the connection establishment, and the received BSM transmits the file from the corresponding file to the MD side.

If the connection check procedure is described with reference to FIG.

This procedure is to check the status of the application and link to send the corresponding message for each port. The heartbeat is transmitted to the BSM in 1 minute increments, and the response to the heartbeat is waited until 1 minute, which is a transmission cycle. If there is no response, the MD should close the socket and let the administrator know and act on it.

After receiving the heartbeat, the BSM sends a heartbeat response ('HeartBeatAck') in response.

At this time, the BSM fills in the name and file pointer of the file being transmitted in the heartbeat frame.

This information is the file to be sent when the MD sends a 'ConnectionReq', except when the system is first booted up and the connection is disconnected for more than 24 hours due to a long period of failure. And file pointer are used to transfer to the BSM side. Based on this information, BSM can know which file to send and a pointer to that file.

The present invention operating as described above, by providing a TCP / IP communication method for efficiently minimizing data loss due to transmission failure in collecting data for the management of the network management center and each local system, It is to increase the reliability of the transmitted and received data through the accurate transmission of the data.
