Description

  The present invention relates to the field of mobile communication technology, and more particularly, to a method and apparatus for processing early warning information data in an LTE (Long Term Evolution) system.

  With the development of science and technology, mobile terminals play an important role in various fields and play an increasingly important role in people's lives. The mobile terminal is also used to receive public disaster early warning information such as ETWS (Earthquake and Tsunami Warning System) notification information, etc., in addition to basic communication and entertainment functions.

  After the ETWS occurs, the base station (Base Station) receives the ETWS notification transmitted from the MME (Mobility Management Entity, Mobility Management Entity), and the ETWS notification is the ETWS important notification SIB (System Information Block) 10 and And / or the ETWS assistance notification SIB11. The ETWS important notification informs the mobile terminal (UE) of disaster type information, affected area information, and occurrence time information when a disaster incident occurs soon or already, and transmits the message to the UE in 4s. Request that. On the other hand, ETWS auxiliary notification includes auxiliary information related to a disaster, informs the mobile terminal of information such as where to get rescue, and requests to transmit a message to the UE within 10s to 30s.

  The base station transmits the ETWS notification to the UE located in the cell (Cell) related to the base station through the broadcast message, thereby increasing the user's self-relief chance and reducing the disaster hazard.

  Similarly, when it is necessary to stop the broadcast of the ETWS notification by the base station, the MME issues a stop request to the base station. The base station should stop broadcasting the ETWS notification immediately. If you do not stop the ETWS notification broadcast, you will panic and frustrate the carrier. Therefore, it is extremely important for users and carriers to quickly find and solve such failures. Then, the carrier wants a convenient route that can directly view information such as whether ETWS transmission was successful, whether it was transmitted on time, and the main cause of failure.

  Currently, when ETWS occurs, there are MME, Webmaster, and UE, as shown in FIG. 1, which can directly communicate with the base station. Then, the block controlling transmission or stop of ETWS to the base station also includes the base station itself and the MME or webmaster.

  In the prior art, usually, after the base station receives the termination request sent from the MME, it completes the related operation according to the MME request, and then other cells of the base station broadcast a specific ETWS notification. It is detected whether or not it is notified to the MME, and the MME performs the subsequent processing. The MME has to add the corresponding processing block to perform the subsequent processing. Then, after the base station receives the ETWS message, the base station may set a timer and stop broadcasting of the ETWS notification when the timer reaches a specified time.

  According to the existing technology, at least, when an MME failure occurs due to a disaster, all the base stations connected to the MME can not receive the ETWS communication stop message from the MME, or the base station does not receive the ETWS notification from the MME. There is a problem that the base station does not stop the broadcast of the ETWS notification, and a problem that the broadcast of the ETWS notification does not stop when the timer breaks down.

  The embodiment of the present invention further provides a network element, which includes the early warning information data processing device described above, and the network element can be a base station, an MME or a webmaster. The base station, MME or web master includes a processor, a program storage device, and a data storage device.

  Hereinafter, the processing method of the early warning information data of the present invention will be described in detail by specific embodiments.

Example 1
In the present embodiment, the case where the early warning information data processing apparatus is disposed on the web master will be described as an example, and the following steps 101 to 106 are included:
In step 101, the ETWS execution module of the base station receives the ETWS command information transmitted from the MME.

  In step 102, when ETWS occurs, the collection module of the base station collects ETWS information data.

  When collecting, information such as SIB10 and / or SIB11 message reception time, SIB10 and / or SIB11 transmission start time, SIB10 and / or SIB11 transmission stop time is mainly acquired.

  In step 103, the collection module of the base station mainly interacts with the webmaster to acquire webmaster SFTP (Secure File Transfer Protocol) information, and then, by SFTP, the ETWS information data to the webmaster server Send.

  By recording a detailed log (log) in the process of collecting data, the base station can record detailed information of each transmission and reception. The summary log and the detail log are associated by a uniform serial number to form complete ETWS LOG data.

  In step 104, the webmaster's data analysis module performs ETWS data analysis after receiving ETWS LOG data.

  Here, ETWS data mainly includes core data such as the time when each cell in the base station receives the ETWS notification, the transmission start time when the ETWS notification has started to be transmitted to the user, and the time when the ETWS notification transmission is finally stopped. including. Through analysis of the data, core indicator data such as transmission delay and stop delay of SIB10 and / or SIB11 are obtained, and thereafter, whether ETWS is effective, normal or abnormal is calculated from these indicators . SIB10 and SIB11 are conclusive information such as non-transmission, transmission delay, small amount transmission, and non-stop.

  First, the data analysis module of the webmaster can identify the validity: complete ETWS records are "SIB 10 received information & SIB 10 transmitted information & SIB 10 end information" or "SIB 11 received information & SIB 11 transmitted information & SIB 11 end information" or both Is included, otherwise it is an incomplete record. The complete records are divided into "normal" records and "abnormal" records depending on whether the transmission delay, stop delay indicator exceeds a threshold.

Here, the calculation rules of transmission delay and end delay of SIB10 and SIB11 are as follows:
Transmission delay = transmission time−reception time. If the transmission delay exceeds the transmission delay threshold, transmission abnormality is recorded, and if the transmission delay is less than the transmission delay threshold, transmission normal is recorded.

  End delay = end time-transmission time. If the end delay exceeds the end delay threshold, the stop abnormality is recorded, and if the end delay is less than the end delay threshold, it is recorded as normal.

  And even if LOG is not complete, it may be abnormal. For example, if there is reception information but no transmission information and no end information, it is abnormal. Also, for example, there is reception information and transmission information, but if there is no end information, it is abnormal.

  In step 105, the failure handling module of the webmaster determines the failure level based on the analysis conclusion and, if the failure is a severe level failure, sends a resolution command message corresponding to the failure code to the base station based on the failure code. Do. If the failure level is low, the flow is terminated because the predetermined level has not been reached.

  In step 106, the ETWS execution module of the base station executes an operation corresponding to the instruction after receiving the solution instruction message transmitted from the web master (for example, transmission of ETWS notification or related operation such as transmission stop). The ETWS strict level failure can be eliminated to realize the purpose of disaster recovery.

Example 2
Based on Example 1, the user can investigate ETWS information.

  The user can start an ETWS information survey job on the webmaster, select multiple network elements, and investigate cell information with all ETWS anomalies, or survey ETWS information with all cells. The result information can also be displayed graphically, regardless of whether or not there is an abnormality.

One ETWS data can include SIB10 or SIB11, or both, and the display status is as follows:
When at least one in the SIB 10 or SIB 11 is invalid, it is displayed as invalid.

  Although both SIB10 and SIB11 are effective, if at least one is abnormal, it is displayed as abnormal.

  When both SIB10 and SIB11 are valid and all the indicators are normal, it is displayed as normal.

  Display strategy of the whole figure: When trying to locate an anomaly of the whole network at high speed, several base stations have to determine whether there is an abnormal cell within a specific time interval. In that case, when any cell of the base station has an abnormality {or invalidity} within a specific time interval, all cells in the abnormal {or invalidity} state of the base station are displayed. If it is possible to specifically grasp, the abnormal cell can be clicked to display how many times the ETWS message has been transmitted within the specific time interval. When group (group indicates the next ETWS recording information of a cell) is clicked, time interval information and numerical values of specific indicators can be obtained. Such core data enables the user to clearly and intuitively grasp information on each ETWS of each cell.

Example 3
Based on the first embodiment, the ETWS statistical analysis function on the webmaster is activated to statistics ETWS occurrence distribution status for one cell, one base station or plural cells, and plural base stations over a long period of time. Can be analyzed.

  Although ETWS faults can be resolved in real time based on the ETWS fault tolerant method of the network management system, the ETWS Information Survey job can also provide the operator with intuitive conclusions to improve user satisfaction. In the network management system, multiple base stations can be simultaneously surveyed, analyzed and drafted, and an instruction message can be automatically sent to the base station to solve ETWS failure. If you do ETWS fault tolerance with a webmaster, there is no need to increase the cost of additional hardware, and there is no need to deploy other software systems, and you can easily obtain cell-related information in the webmaster database for analysis and analysis. Can participate in the check.

  The network management system is a network application system in which software and hardware are combined to make software as a main object, and aims to manage the network and operate the network most efficiently and normally. Thus, there is no need to integrate ETWS fault tolerant functionality into the network management system to take advantage of existing data paths and increase extra network costs. The relevant information of the base station's cell can be easily examined to perform ETWS fault tolerant processing. When integrated into a network management system, high-speed positioning can be performed simultaneously on a plurality of base stations, so here, the ETWS fault tolerant function is integrated into the network management system and described.

Example 4
The embodiment of the present invention is applied to the commercial mobile early warning service (CMAS) status, and a specific implementation will be described using the traffic management status as an example. Steps 202 to 206 are included.

  In step 201, the base station receives the traffic management information transmitted from the upper management system.

  At step 202, the base station collects traffic management information.

  Mainly, information such as traffic management information reception time, traffic management information transmission start time, and traffic management information transmission stop time is acquired.

  In step 203, the base station sends the collected traffic management information to the webmaster).

  At step 204, after traffic management information is concentrated on the webmaster, the webmaster performs data analysis.

  Transmission delay = transmission time−reception time. If the transmission delay exceeds the transmission delay threshold, transmission abnormal is recorded, and if the transmission delay is equal to or less than the transmission delay threshold, transmission normal is recorded.

  Stop delay = stop time−transmission time, and if the stop delay exceeds the stop delay threshold, a stop abnormality is recorded, and if the stop delay is less than the stop delay threshold, the stop normal is recorded.

  And there is a possibility that there is an abnormality even if the traffic management information is incomplete. For example, if there is received information but there is no transmitted information and no end information, it is always abnormal, and for example, there is received information and transmitted information, but it is always abnormal if there is no end information .

  In step 205, the webmaster determines the failure level based on the analysis conclusion, and if it is a severe level failure, transmits a resolution command message corresponding to the failure code to the base station based on the failure code. If the failure level is low, the flow is terminated because the predetermined level has not been reached.

  In step 206, after receiving the resolution command message sent from the webmaster, the base station executes an operation corresponding to the command to clear the fault of the strict level of traffic management information, and immediately clear the traffic management information. Achieve the purpose of accurately issuing or stopping the publication.

  The program can be completed by instructing a related hardware by a program to perform all or part of the steps of the method described above, and the program can be stored in a computer readable storage medium such as a read only memory, a disc or a CD. Those skilled in the art can understand what can be done. And all or part of the steps of the above embodiment can be realized by one or more integrated circuits.
