Description

How to transfer and store data to the parent system

The present invention relates to a method of transmitting and storing data to a higher system, and in particular, manages a network that manages information on important events occurring in a lower system for management and maintenance of the system. It relates to a method for using the system more efficiently by transmitting it to a network management system (NMS) as a basic data for management and maintenance.

One embodiment of a mobile communication system using a Code Division Multiple Access (CDMA) scheme includes a mobile terminal (MS) that is basically mobile as described in US Pat. No. 5,673,260; It is composed of a plurality of base stations serving a certain area.

At this time, the base station is connected to an existing Public Switched Telephone Network (PSTN), and a mobile terminal in each cell forms a radio channel with a base station serving a corresponding cell and performs communication.

In this case, a channel formed in the direction of the mobile station from the base station is called a forward channel, and a channel formed in the direction of the base station from the mobile station is called a reverse channel.

The mobile station and the base station transmit and receive voice information and data by using a traffic channel, and pilot, synchronous, and paging channels except for the traffic channel are transmitted and received. It is called an additional channel, ie an overhead channel.

Each base station and mobile terminal determines whether it should receive the data through pilot or paging (or code) transmitted on additional channels.

Each base station is assigned several frequencies according to system capacity and uses as many frequency channels. Each frequency channel is called frequency assignment (FA).

CDMA systems can include multiple access channels by varying frequency offset and sequence per frequency channel.

In a mobile communication system, systems below the switching center system are commonly referred to as Base Station Subsystem (BSS). The base station sub-system consists of a base station management system, a base station controller system, and a base station system in an upper order.

The main processor of the base station controller system is called a Call Control Processor (hereinafter referred to as CCP), and the main process of the base station system is called a BTS Control Processor (hereinafter referred to as BCP). do.

In addition, the processes of CDMA and PCS systems are as follows. The SIP (Selector Interface Processor) performs call connection control and radio link control. The channel interface processor (CIP) manages channel elements and controls the interface.

In addition to the various processes described above, high capacity interprocessor communication node processors are included.

In the mobile communication system, many base station equipments are managed under the maintenance equipment. In a communication system, the processing of these data is very important because the information of each event (failure, alarm, or status change) is important.

Event data generated in the lower system is reported (uploaded) to the upper system, and a special protocol is required for data transmission processing between these systems.

A prior art for a method of data transmission and storage between upper and lower systems is disclosed in US Pat. No. 5,664,100. In this method, each sub system (Client) attaches the code for the system to the transferred file and sends it to the upper system (Server). The transmitted information is safely transmitted to the upper system when no failure occurs in transmission. If any failure occurs, the transmitted information is stored in the memory device and subjected to other processing.

The data that failed to be transmitted is called backup data, and processing such backup data is one of very important process in a communication system having a complicated parent / child structure. Therefore, there is a need to construct a new data transmission protocol suitable for the structure of a mobile communication system.

Important contents managed in each system of the mobile communication system are data on faults and alarms for each device constituting the system, data on state of devices and processes, shape information data, and performance data for each base station. In addition, the actual upper maintenance data is a function for command processing and historical log data.

In actual mobile communication systems, important information has been kept for a certain period of time. This is because if a serious abnormality is detected in the system, the history can be identified and corrected through various historical logs.

The operation maintenance center collects and maintains the information managed in each control system as the main system in order to collectively manage distributed systems on the operator side.

Each system such as base station control system, base station management system, home subscriber registration system, etc., which constitutes mobile communication system, operates multiple BSC-MSCs for each region, so many sub-systems are interworked with the actual network management center. .

1 is a block diagram showing the structure of a network management center. As shown, the network management system (NMS) is connected to a switch (PCX) or home subscriber registration system (HLR) and base station management system (BSM) via a hub.

The base station management system has a base station control station (BSC) connected to the base station, and the base station control station has a base station (BTS) control processor (BCP) and a SIP (Selector) for call connection control and radio link control. Interface Processor).

As described above, the network management center operates several base station systems, an exchange office system, and a home subscriber registration system together. The network management center recognizes the status of the system through parsing and location information on each sub-system. Finally, maintain it so that it can be efficiently managed without affecting call services and other maintenance functions.

In a mobile communication system including a base station secondary system, a base station management system, a network management center, and the like, when an event occurs in the base station secondary system, corresponding information is reported to the base station management system. The data is then recorded in the history using a particular file system.

Each record is recorded according to the schedule file name of year, month, date, time, MHD (Message History Data) for easy management.

In addition, the information performed by the operator is recorded in the year, month, date and time. CHD (Command History Data), and the information performed by the remote terminal is recorded in the year, month, date, time, and RHD (Remote command history data).

In addition, performance statistics data is stored in year and month date and time. HDOF (HanDOFf data), and performance data excluding handoff are stored in year and month date and time.OTHER.

In fact, the meaningful data to be sent to the network management center can be divided into fault, alarm, performance, status, configuration information and command processing information, and each socket is assigned a separate socket port number for load. It is distributed so that data can be transmitted.

Table 1 shows the types of ports for distributed transmission of data.

Distributed transport port Port name Port number Data type ALM_FLT_PORT 8282 Fault / alarm data SHORT_STAT_PORT 8283 Real time performance data LONG_STAT_PORT 8284 Extender Performance Data STATUS_PORT 8285 Status and Geometry Data MMC_PORT 8286 Instruction processing BACKUP_PORT 8287 Backup data

Since the contents of the message in the base station management system are stored in a file, the transport block monitors the data file point of the corresponding time zone and reads the data when a new message is generated and transmits the data to the counter network management center.

In particular, in the base station management system, data is stored for one week for each time zone, so when the current time is obtained, a specific file can be accessed and sent to detect and send.

Table 2 shows the types of files transmitted for each port identified by Table 1 above.

Type of file to transfer by port File type BSM History File Name Port number MML_File Files Related to MMC Input (Deprecated) 8286 MHD_File ~ / HISTORY / MHD / * files 8282 STATUS_file ~ / HISTORY / MHD / * files (status, shape data) 8285 CHD_File ~ / HISTORY / CHD / * files (command related details) 8285 RHD_File ~ / HISTORY / RHD / * files (remote command history) 8285 STAT_LONG_OTHER ~ / HISTORY / RHD / *. OTHER files (hourly statistics file) 8284 STAT_LONG_HDOF ~ / HISTORY / MHD / *. HDOF files (hourly handoff statistics file) 8284 STAT_ONLINE_OTHER ~ / HISTORY / MHD / *. OTHER files (statistic required) 8283 STAT_ONLINE_HDOF ~ / HISTORY / MHD / *. HDOF files (requested handoff) 8283

Each port manager reads the contents of the defined history file and transfers any newly added data. At this time, since the data to be read is decided, each file can be monitored to transmit the latest information.

All of the above data can be retransmitted to a separate spare port called a backup port. In fact, the latest events are sent to their respective current ports, and the unsent data is sent to the backup port.

In order to transfer data to the backup port, the untransmitted data must be saved through a separate backup tool (Scheme).

In general, data for backup should be managed in a separate buffer and stored in the buffer if transmission is interrupted. Since the amount of data in the base station sub system is very large, the buffer size should be largely allocated. Therefore, it is a big variable to properly predict the size of a sufficiently large buffer.

In addition, when the data stored in the history is double-stored by writing it to a separate buffer once again, the speed of writing / reading process is that much, and as a result, it is not a desirable way to judge the performance of the overall base station management system. This exists.

If the data transmission from the lower system to the upper system fails, only the stored port should be read and transmitted without the need for additional buffering for the already stored data. Therefore, the part to be processed must be managed.

In the present invention, not all data which cannot be actually transmitted are transmitted to the backup port, and data within a predetermined time is transmitted to the current port, and data past that time are transmitted to the backup port. This time is based on 5 minutes of backup time.

In fact, if a port is disconnected and then reconnected periodically, the time for which the connection is interrupted should be measured to determine whether to send data that has not been sent to the current or backup port.

2 is a diagram illustrating a backup due to data transmission interruption and reconnection. As shown in the figure, when a failure occurs during transmission and transmission is interrupted and retransmission is repeated, the transmission is partially read because the file is read and the transmission is interrupted in a certain unit of frames.

2, only A ~ B, C ~ D, E ~ section is transmitted to the current port, and the data generated in other sections (B ~ C, D ~ E section) is 5 minutes. If it is abnormal, it is sent to the backup port.

Since the backup process and the current process operate separately and only the current process knows the point information of the file to be transferred to the backup port, it is necessary to share information between the two processes in order for the backup process to recognize it.

When the process is down in the current process, the last point transmitted so far is the starting point to be backed up, and when the backup process recognizes this information, the current port does not operate normally even if it is more than 5 minutes from that point on. You must transmit from that point.

If the current port starts and operates normally within five minutes, the data generated from the last point up to now are generated within five minutes, so they must be transmitted to the current port.

The current process is to perform a series of transfers and instructions through the following procedures.

The general current port access procedure is as follows.

1) Connection setup procedure.

2) Procedure to start sending and receiving messages.

3) Process status checking procedure.

4) Disconnection procedure.

At this time, the message management stop may be instructed by the network management center to temporarily suspend transmission.

Also, the access procedure of the operator command processing port is as follows.

1) Connection setup procedure.

2) Operator command processing procedure.

3) Process status checking procedure.

4) Disconnection procedure.

Each of the above procedures will be described below.

The connection establishment procedure is a procedure for the network management center to establish a TCP socket connection to the NE, and then confirm the port type and preparation for sending and receiving messages between management application processes on the socket port. The message is "PortTypeConfirm".

The message transmission start indication procedure is a procedure in which the network management center instructs the NE to determine the type of message to be transmitted and received on the corresponding port and to start transmission. The message is "StartMsgTransmission".

The operator output message transmission procedure is a procedure for transmitting an operator's output message, and the message is "OutputMsg".

The process status checking procedure is a procedure in which the network management center periodically checks the status of the management application process of the NE. The message is "AppStatusCheck".

The message transmission and reception interrupt indication procedure is a procedure for instructing transmission and reception interruption of an operator input / output message of a corresponding type being transmitted and received from the NE. The message is “StopMsgTransmission”.

The disconnection procedure is a procedure for terminating a TCP socket normally after the network management center instructs the NE to stop sending or receiving all messages before disconnecting the TCP socket. The message is "ClosePortConnection".

The operator command processing procedure is a command processing procedure required for input from a network management center operator. The message is "InputCommand".

3 is a flowchart illustrating a connection establishment and release process according to the present invention.

Hereinafter, a method of transmitting and storing data to a higher system according to the present invention will be described in detail with reference to FIG. 3.

When the process starts, it sends a "PortTypeConfirm" message to start the connection establishment procedure (s01).

Then check whether the difference between the last time and the current process start time is more than 5 minutes (s02).

If the difference is less than 5 minutes, the data stored in the list for backup is deleted from the list (s03).

Transfer the data within 5 minutes using the last transfer point as the transfer start point. (S04)

The newly generated data is transmitted by continuously monitoring the file whose message type is not Stop (s05).

If the "AppStatusCheck" message occurs in the step (s05), the process status check procedure is carried out (s06) and transmits the "AppStatusAck", saves the transmission point so far and returns to the step (s05) (s07).

If the message " StopMsgTransmission " occurs in step S05, the message transmission and reception stop procedure is performed (s08). Then, transmission of the corresponding message type is stopped, and the process returns to the step S05.

If a "ClosePortConnection" message occurs in step S05, the connection release procedure is performed (s10) to save the work of the current process and stop the transmission (s11).

If the difference between the last time and the current process start time in step (s02) is 5 minutes or more, the data from the point where the previous process was last transmitted to the point of the current file is converted into data for the backup port (s12).

The current final file name and file point are stored as a starting point (s13).

In step S05, the message type is not terminated, but the file is continuously monitored to transmit newly generated data, and a connection procedure suitable for the generated message type is performed.

As each current process starts up, it does several things with reference to the information from the previous process.

First, the end time of the previous process determines whether data between the last transfer point and the current point is sent to the backup port or the current port. You should also know this point since the point at which the previous process received the last "AppStatusCheck" is the start of the backup or current port.

In order to inform the new process of the information of the old process, the process always writes its information to a file at the last point in time (s11 in FIG. 3), and the new process accesses this file to get the information.

4 shows an information table for process management.

As shown, the information obtained at startup of the process is presented by port.

Through the table information shown in FIG. 4, the current process distinguishes the backup data from the current data, and the backup data is processed as the information for backup, and the start point of the transmission is known through the following file type information.

When the current process receives the "StartMsgTransmission" after completing the connection setup procedure, it should read and transmit the specified file to be transmitted by port.

5 shows an information table for data transmission.

The start of data transfer depends on the time period of the previous process and the current process. If the time difference is more than 5 minutes, the data generated in between should be sent to the backup port, not the current port.

Then, the data is transferred to the backup port so that the data from the last file (Efile), last offset (Eoffset), and filename at the beginning of the current process to the file point are transferred to the backup port. Make a note of the file you are accessing.

The contents sent to the current port are the file name and file point at the beginning of the current process.

If the time difference between the previous process and the current process is less than 5 minutes, then all data up to that point must be sent to the current port, not the backup port.

Then, from the last Efile and Eoffset point transmitted by the previous process, the starting point of the current process should be transferred.

When the process ends, it always sends the data to the backup port at a later point, based on the point that has been sent so far. The backup process uses this information to determine the starting point to send.

In the backup process, the information to be transmitted from the backup port is processed as a double-linked list for each transmission part, and the backup process can identify and transmit the start and end points of the data to be transmitted through the information.

Since the transfer information is managed by file type, there is no delay in processing speed as the list grows, and the information about the actual backup point is owned by each current port.

In fact, the process of using this information to read data from the starting point to the end point and handling the transfer is a backup process.Backup information is a backup process because processing information using a common file can cause information to be lost due to an interprocess interrupt. Have a dedicated list manager.

Since the exchange of information between the current process and the backup process is a one-way communication of the backup process from the current process, this information is conveyed in three types:

(1) ADD List

In addition to the list, when the current process terminates, it is delivered when the current process receives the "StartMsgTransmission" instruction 5 minutes after receiving the "StopMsgTransmission".

(2) DELET List

Deleting a record from the list. Deletes a previously added record when it is restarted within 5 minutes of the end of the current process. If the backup process continues the transfer, the end point is reached, but the list is deleted.

(3) CHANGE List

If a particular field of the list needs to be changed, the last point in the list added at the end of the previous process should be changed to the point in the current file if the current process is restarted after a five minute interval.

6 shows an information table for transmission through the backup port.

Since the backup port can send all kinds of data, it extracts all the list that needs to be processed first by file type from the double linked list, and if the list is valid, it starts data transmission by applying the priority of each list.

The list can be processed as a list of information across multiple files, so check with the Efile and Eoffset of the list to see if the part you are currently transferring matches. If the file name is different and the file name being transferred is not current time data, If it is time data, 0 point of data of next time zone is sent as start file (Sfile) and start offset (Soffset) again.

If the transfer of historical data continues, eventually a point matching the final Efile, Eoffset will occur and the list will be deleted.

If the current port is interrupted and the transmission is interrupted, the current data should be transmitted after the list processing for the past data is completed.

Indications for this are distinguished as follows.

[MHD file: message history data]

(1) When the final point is determined

~ / HISTORY / MHD / 19970930.TUE / 10.MHD, 2940 (Sfile, Soffset)

~ / HISTORY / MHD / 19970930.TUE / 15.MHD, 3598 (Efile, Eoffset)

If the final point is defined as above, it processes all 11.MHD, 12.MHD, ..., 14.MHD with 2940 offset of 10.MHD as starting point, and then transmits up to 3958 points of 15.MHD. . This list will then be deleted from the backup information.

(2) The final point is not determined

~ / HISTORY / MHD / 19970930.TUE / 10.MHD, 2940 (Sfile, Soffset) NULL, 0 (Efile, Eoffset)

If the final point is not determined as described above, the current port remains in a failed state after 10 minutes on September 30, 1997, and is not recovered, and the 2940 offset of 10.MHD is used as the starting point. Send the data.

Efile and Eoffset are pointless here, so the backup process will continue to transfer files until it can process the current time.

In other words, if the current system time is 17 o'clock, 10.MHD, 11.MHD, ..., 16.MHD are all sent to the last part, and then 17.MHD is continuously monitored and any additional data is detected and transmitted. .

In this case, it should be noted that in the case of (2), it is assumed that the current port is in a failure state, and (2) the current port can be restarted in the middle of processing the list.

If this is a restart within 5 minutes, the list should be deleted. If it is a restart after more than 5 minutes, Efile, Eoffset will be the last file offset of the current time, and the backup process will be sent only up to that point.

The present invention can be applied to various systems that are applied to the network management center and the TCP / IP socket (Socket) communication.

In the detailed description of the present invention, specific embodiments of the present invention have been described, but various modifications are possible without departing from the scope of the present invention.

That is, in the present invention, the base station sub-system, the base station management system, and the home subscriber registration system, which constitute the mobile communication system, are described. However, all kinds of sub-systems that transmit data to one higher-level system and the higher-level system are described. Applicable for the system.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

Thus, data can be transmitted accurately to be a basis for more accurate identification and judgment of the system, and data loss can be prevented by transmitting data as a backup in case of a transmission failure.

In particular, since the amount of data generated from the base station management system is much higher than that of other systems, it reduces the burden of dual data management by buffering these data as a backup, and the network management center, which is a higher-level system without losing the stored local data. To be sent to.

In a host system and a plurality of subsystems that transmit data to the host system, data failed to be transferred to the host system can be managed by managing the points of the history file without backup buffering to transfer the failed data to the backup port. Retransmission, data transfer and storage method using current process and backup process. In a host system and a plurality of subsystems that transmit data to the host system, when the connection of the current process is established, the decision of backup and data transfer to the current port is made through the information of the previous process. A method of transferring and storing data using current and backup processes that obtains the necessary basic data through a process information table that records its own information. 8. The data according to claim 7, wherein the information table is dually linked to the current process and the backup process so that the backup process can identify the start and end points of the backup data to be transmitted via the information. How to transfer and store. 9. The backup process according to claim 8, wherein the backup information of the information data table is managed exclusively by a backup process, and information exchange between the current process and the backup process uses one-way communication from the current process to the backup process. How to transfer and store data using a process. The method of claim 7, wherein the port-specific data table of the process information, A field representing a table name; A field indicating a process port Id; A field indicating a process port type; A field indicating a process status; A field indicating an end time of a previous process; Finally, a method for transmitting and storing data using a current process and a backup process, including a field indicating a time when a process status check message is received. The data type file table of the process information according to claim 7, A field indicating a type of data transmission port; A field indicating a file type; A field indicating a name of an information table; A field indicating a message sequence Id for each port / file type; A field indicating a size of a transmitted message for each port / file type; A field indicating a transfer start file name of a process now serving; A field indicating a point in the transfer start file of the process now serving; A field indicating a last file name last transmitted; And A method of transferring and storing data using a current process and a backup process, comprising a field indicating a point of the last file last transferred. In a host system and a plurality of subsystems that transmit data to the host system, when the information of the various types of files backed up are transferred through the backup port, the historical data is sequentially read by applying priority for each time zone. , How to transfer data to a higher system. In a host system and a plurality of subsystems that transmit data to the host system, when processing information about backup data that failed to transfer to the host system, the start file name, start offset, and final A method of transferring data to a higher level system that processes a list using a file name and a final offset as one configuration information. The method of claim 13, wherein the list of backup information, When the current process ends, it is added when the current process receives a message to start sending or receiving messages more than 5 minutes after receiving the message to stop sending or receiving messages. If the current process is restarted within 5 minutes of termination, the previously added record is deleted, and the backup process continues the transfer and deletes the list when the final point is reached. A method of transferring data to a higher level system that changes the last point in the list added at the end of the previous process to the point in the current file if the current process has been restarted after five minutes. In a higher system and a plurality of lower systems that transmit data to the higher system, If the current process is reconnected while the backup process is transferring the backup data to the upper system, and deletes the backed up data list if it is restarted within a predetermined backup reference time; A method of transferring data to a higher level system that, if it is restarted after a predetermined backup reference time, transfers only the last file offset of the current time to the backup port and then to the current port.
