Description

Method for providing abnormal information, network self-diagnosis method, terminal and communication network

The present invention relates to the field of wireless communications, and in particular, to a technique for providing abnormal information in network self-diagnosis. Background technique

With the development and application of communication technologies, the scale of the network has rapidly expanded and the number of users has been increasing. The quality of services has received more and more attention. In the normal communication service, the network may be faulty due to various reasons, such as: improper network power setting, abnormal cell parameter configuration, abnormal cell signal fluctuation, etc., so that the terminal cannot reside on the cell, or the terminal is stationed. The staying cell initiates a call request, but does not receive a network response. In the application of communication technology, frequency resources are limited in cellular wireless mobile communication systems, and therefore, the system capacity of the communication system is usually provided by frequency multiplexing. However, frequency reuse also brings about an increase in the number of cells in the network, which brings great difficulties for network maintenance operations. In addition, in areas where communication network application density is not high, such as: rural market, the initial stage of network construction, etc., usually a single cell coverage, when these networks have abnormal conditions, it will lead to a vacuum in the coverage of the communication network.

In order to solve the problem that the communication network is abnormal, the general solution in the prior art is: performing statistical analysis on the network side through the cell telecommunication statistics data. When the statistical data is abnormal, the cell is initially determined to be a fault cell, and then, The road test is then carried out manually to the site for further verification. For the faulty cell, report the detailed fault information, locate the fault, and take action.

The inventors of the present invention have found in the course of implementing the present invention that the prior art solutions have the following disadvantages:

It is unreliable to determine whether the cell communication network is normal through telecommunication statistics, because the telecommunication statistics are normal and cannot guarantee that the cell coverage area is normal, so that all the abnormalities cannot be accurately found. For example, when the power transmission of a certain cell is not large enough, users in the vicinity of the cell can receive services normally, but the users outside the cell have service failures, and the telecommunication statistics cannot reflect such anomalies well. In addition, when there is no data for the call in a specific area or a specific time period, the user does not request the service within a certain period of time. At this time, the telecommunication statistics will be reflected as abnormal, and the cell is considered to be faulty, but in fact, the telecommunication statistics Data anomalies have nothing to do with cell failures, resulting in additional invalidity and increased overhead.

The solution to the failure of the communication network through telecommunication statistics also has the problem that the feedback network failure is not timely. Telecommunications statistics are usually statistically analyzed in units of time periods, such as one hour. Therefore, when a network fails, the timeliness of fault feedback is not guaranteed, and the fault cannot be diagnosed and processed in time.

Summary of the invention

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, it will be further described below in conjunction with the accompanying drawings and specific embodiments.

The following describes a first specific embodiment of the embodiment of the present invention, and relates to a network self-diagnosis. For the method of providing the constant information, referring to FIG. 1, the method includes:

Step 101: Set a cell with an abnormal information reporting function.

In a cell in the entire communication network, a part of the cell may be configured to have an abnormal information reporting function, or all the cells may be configured to have an abnormal information reporting function according to the actual situation of the network. The setting of the abnormal information reporting function for the cell may be dynamic, and the cell may be set to have such a function, and the set function may be cancelled. After the cell is configured with the abnormal information reporting function, the cell may indicate that the cell has a reporting function in an explicit or implicit manner. The method for the cell to indicate that the cell has the reporting function in an explicit manner may include the following two types. First: indicating, in the sent cell broadcast information, that the cell has the function, for example, the indication of the cell broadcast information may be adopted by the cell system. One bit in the broadcast message is indicated; second: the cell informs the terminal through dedicated signaling that the cell has a reporting function. The method for the cell to indicate that the cell has the reporting function in an implicit manner includes: the cell passing the cell identifier or the cell scrambling code, indicating that the cell has a reporting function.

In this embodiment, the cell may be allowed to change the status of the reporting function, that is, the network may set the cell with the reporting function to the cell that does not have the reporting function, or set the cell that does not have the reporting function to the cell with the reporting function, when the cell is changed. After the reporting function status of the cell, the cell indicates the state of the cell in an explicit or implicit manner. The specific indication method is the same as the method for indicating that the cell has the upper function, and details are not described herein again.

Step 102: The terminal records the abnormal information.

The terminal has the function of recording abnormal information. When some abnormal conditions occur in the network where the terminal is located, the abnormal conditions in the network can be recorded and saved.

The abnormal situations that often occur in the network are as follows: The terminal camping cell selection fails. At this time, the terminal can record the resident cell selection failure information, such as: the number of reselection failure errors, the reason for the reselection failure error, etc.; the terminal call fails to be initiated. The terminal may record the number of call initiation errors, the reason for the call origination failure, and the like, and the cell signal is abnormal; the terminal may record information such as frequent and severe jitter of the cell signal; when the terminal cannot camp on the cell, the terminal record cannot be resident. Case. Of course, the abnormal network conditions recorded by the terminal are not limited to the enumerated ones. For abnormal information that may appear in the network, or for information that can be used for network self-diagnosis, the terminal can record the same. Similarly, when the network appears, the network cannot directly When the exception information is obtained, the terminal can also record.

The abnormal information recorded by the terminal may be invalid in the following cases: After successfully entering the cell with the abnormal information reporting function, after the terminal reports the abnormal information, the abnormal information recorded in the terminal is invalid, or when the terminal will After the exception information is successfully reported, the abnormal information recorded in the terminal is invalid after a set time; after the terminal successfully enters a cell that does not have the abnormal information reporting function, the abnormal information recorded by the terminal is invalid; or the terminal does not have the abnormal information. At the time of reporting, after a set time, the abnormal information recorded by the terminal is invalid. The abnormal information recorded by the terminal is invalidated to avoid causing a large load on the terminal. The terminal can also prevent the terminal from recording the abnormal information of the network and then feed back to the network after a long time, so that the fault analysis is not timely or inaccurate.

Step 103: The terminal reports abnormal information.

After the terminal records the abnormal information and enters the cell with the abnormal information reporting function, the cell broadcasts the message, or the dedicated signaling sent by the cell, or the cell identifier, or the cell scrambling code, to learn that the cell has the abnormal information reporting function. The terminal initiates a random access request, and the terminal accesses the cell, and the recorded abnormal information is reported to the network, and the abnormal information is reported.

The abnormal information on the terminal may also be completed in the process of the terminal accessing the cell. After entering the cell, the terminal uses the recorded abnormal information as the out-of-band information or in-band of the random access during the process of initiating the random access. The information is sent to the network, thereby completing the reporting of the abnormal information.

At this point, the network obtains the abnormal information needed in the network self-diagnosis process.

In the technical solution provided by the embodiment, the abnormality information reporting function is set on the cell network, and when the terminal records the abnormality information of the network, the abnormal information is reported to the cell after entering the cell with the abnormal information reporting function, so that the network A network anomaly is obtained, so that further analysis and positioning can be performed. The disadvantages of inaccurate and untimely methods of relying on telecommunication statistics to determine faulty cells in prior art methods are addressed. In order to enable a person skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present invention, the following abnormalities occur in the network: the terminal camp cell selection failure, the terminal call initiation failure, and the cell signal abnormality are as an example. The method for providing abnormal information in the network self-diagnosis shown in FIG. 1 will be specifically described.

1. The terminal camped cell selection fails.

When there is a hole in the network coverage, or the coverage area cell refuses to work, the terminal cannot detect the cell, or the terminal can detect the cell, but cannot satisfy the camping condition, so that the terminal resident cell selection fails. At this point, the terminal records the corresponding information, such as: Time/location where the network has an abnormality

(in the case of GPS), the discovered cell (which can be found but can't be parked), or other information that may be helpful (such as route); after the terminal returns to the network, it immediately initiates access and will record The information about the failure of the camping cell is fed back to the network, or when the terminal has a service demand, the information recorded by the service process signaling is fed back to the network, so that the abnormal information is reported. After the terminal reports the abnormality information to the network, the network obtains the abnormal information reported by the terminal, and uses the abnormality information for the self-organizing service. For example: It is found that a certain area is a coverage blind area, and it is necessary to increase the area of the cell or adjust the coverage of the surrounding area. It is found that a certain area is covered but becomes a blind spot. It is checked whether there is a failure of the cell, and further positioning and tracking is performed immediately.

The method for providing abnormal information in the network self-diagnosis provided by the embodiment of the present invention can automatically collect network information and network faults, and solves the problem that the network cannot automatically track and identify the abnormal information in the prior art, and the abnormal information needs to be manually obtained. The problem of abnormal information acquisition is not timely.

2. The terminal call failed to be initiated.

When the receiving signal of the base station fails, or the receiving signal antenna is occluded, the terminal can camp on the cell, but the network does not respond to the terminal initiating the call request (it is considered that the gateway does not detect the call request), so that the terminal call fails to be initiated. At this time, the terminal records the corresponding abnormal information, for example: cell or location information; immediately after the terminal returns to the network, initiates the access, feeds the recorded abnormal information to the network, or when the terminal has a service demand, with the service The process signaling feeds back information to the network, thereby completing the reporting of the abnormal information. After the terminal reports the abnormal information to the network, the network obtains the end. The abnormal information reported by the terminal, and the exception information is used for the self-organizing service. For example: Combine some other information (whether the telecommunication management network TMN data is normal information), check whether there is a cell failure, and immediately further locate the tracking.

The method for providing abnormal information in the network self-diagnosis provided by the embodiment of the present invention can automatically collect network information and network faults, and solves the problem that the network can only perform statistics on the received call request, but cannot fail to initiate the terminal call. The call request is counted, and the statistics need to be obtained manually, resulting in the problem that the statistics are not obtained in time.

3. The cell signal is abnormal.

When the interference environment around the cell is relatively bad (such as burst or periodic interference or complex surrounding environment), the base station itself cannot perceive the situation, and the terminal can perceive that the cell signal changes frequently and violently. At this time, the cell can satisfy The camping condition, if the terminal can initiate a service on the base station, the terminal can detect that the cell signal is abnormal through the network. At this time, the terminal records corresponding abnormal information, such as cell information or fluctuations, etc.; after the terminal returns to the network, immediately initiates an access, feeds the recorded abnormal information to the network, or when the terminal has a service demand, As the service process signaling feeds back information to the network, the reporting of the abnormal information is completed. After the terminal reports the abnormal information to the network, the network obtains the abnormal information reported by the terminal, and uses the abnormal information for the self-organizing service. For example: It is found that there is an external interference source around; or the location of the base station is inappropriate, causing some location wireless conditions to be abnormal; or several base stations have application failures.

The method for providing abnormal information in the network self-diagnosis provided by the embodiment of the present invention can automatically collect network information and network faults, and solves the problem that when the cell signal is abnormal in the prior art, if no service is initiated, the terminal can acquire the abnormal signal. , and the network side cannot obtain the problem of the abnormal signal.

A second embodiment of the present invention is described below, and relates to a method for providing abnormal information in network self-diagnosis. The second embodiment is basically the same as the first embodiment, and the difference is that the manner in which the cell obtains the abnormal information reporting function is different in the network. In this embodiment, the abnormal information reporting function of the cell does not need to be set by the network. But by the default setting of the cell itself In this way, the cell abnormal information reporting function may not be indicated by the network in an explicit or implicit manner. The following describes a third embodiment of the present invention. A method for network self-diagnosis includes:

Step 301: Set a cell with an abnormal information reporting function.

The abnormal information reporting function of the cell can be set by the network or by the default setting of the cell itself. When the default setting is used, the network does not need to indicate the cell abnormal information reporting function in a display or implicit manner.

Step 302: The terminal records the abnormal information.

Step 303: The terminal reports the abnormality information.

Steps 301 to 303 are substantially the same as steps 101 to 103 in the first embodiment, and are not described herein.

Step 304: Network troubleshooting.

After the terminal completes the reporting of the abnormal information, the network obtains the abnormal information in the network through the cell with the abnormal information reporting function, analyzes the cause of the abnormality according to the abnormal information, and analyzes and locates the diagnosis according to the background telecommunication statistical data. Network failure. In complex cases, it is also necessary to combine the determination of the test-assisted faults in a targeted manner in the field. Then, the faulty site is processed in a manual or automatic manner in time.

Through the solution provided in this embodiment, when an abnormal situation occurs in the network, the terminal can use the terminal to record the abnormal information in time and report it to the network to diagnose the network fault, so as to further solve the fault in the network in a timely and accurate manner.

A fourth embodiment of the present invention is described below. With respect to a terminal 200, referring to FIG. 2, the terminal 200 includes:

The abnormality information storage unit 201 is configured to record and store the abnormality of the network where the terminal is located when the network where the terminal is located is abnormal or faulty. For example, the following abnormal conditions often occur in the network: The terminal camping cell selection fails, and the terminal is terminated. The resident cell selection failure information may be recorded, such as: the number of reselection failure errors, the reason for the reselection failure error, etc.; the call initiation fails, and the terminal may record the call issue. The call origination failure information, such as the number of errors, the reason for the call origination error, etc.; the cell signal is abnormal, and the terminal can record information such as frequent and severe jitter of the cell signal. Of course, the abnormal network conditions recorded by the terminal are not limited to the enumerated ones, and the abnormal information that may appear in the network or the information that can be used for network self-diagnosis can be recorded.

The abnormality information upper unit 202 is configured to report the abnormality information stored in the abnormality information storage unit 201 to a cell having an abnormal information reporting function in the network, such as a base station or the like.

After the terminal 200 records the abnormality information and enters the cell with the abnormal information reporting function, the terminal 200 initiates a random access request, and the terminal 200 accesses the cell, and the abnormal information reporting unit 202 records the abnormality recorded by the abnormality information storage unit 201. The information is reported to the network, and the abnormal information is reported. The reporting of the abnormality information may also be performed in the process of the terminal 200 performing the accessing of the cell. After the terminal 200 enters the cell, the abnormal information reporting unit 202 records the abnormal information recorded by the abnormality information storage unit 201 in the process of initiating the random access. It is sent to the network as out-of-band information or in-band information of random access, thereby completing the reporting of abnormal information.

The terminal 200 may further include a processing unit 203 for processing the information stored by the abnormality information storage unit 201, responsible for maintaining the validity of the abnormal information data, discarding outdated and invalid abnormal information in time, and determining to trigger the abnormal data reporting.

A fifth embodiment of the present invention is described below. With respect to a communication network 300, referring to FIG. 3, the network 300 includes:

The abnormality information receiving unit 301 is configured to receive the abnormality information recorded and reported by the terminal. For example, the terminal records the abnormality information, and after the cell with the abnormal information reporting function is entered, the abnormality information is reported to the network, and the abnormality information receiving unit 301 The abnormality information that is reported can be received. The decision unit 303 includes a first decision subunit 3031, and the first decision subunit 3031 is configured to analyze the abnormality according to the abnormality information received by the abnormality information receiving unit 301, and guide the fault. Processing unit 304 implements a fault resolution solution;

The fault processing unit 304 is configured to implement a fault solution according to the first decision subunit 3031. In the communication network 300, the telecom management data unit 302 is further configured to record the telecommunication statistical data information of the network. At this time, the first decision subunit 3031 analyzes the cause of the abnormality, and guides the fault processing unit 304 to implement the fault solution. In addition to the abnormality information received by the abnormality information receiving unit 301, the telecommunication statistical data information recorded according to the telecommunication management data unit 302 can also be considered.

In the communication network 300, the decision unit 303 further includes a second decision subunit 3032. The communication network 300 further includes a report function setting unit 305, configured to set a cell reporting function according to the second decision subunit 3032; Considering the network load in the network, you can set the abnormal information reporting function for some cells. Of course, you can also set all cells to have abnormal information reporting functions according to the actual needs of the network.

With the technical solution provided by the embodiment of the present invention, the terminal records the abnormality information, and reports the abnormality information to the cell with the reporting function, so that the network can acquire the abnormal information in the network in time, and perform network fault self-diagnosis. Through the terminal, all abnormal conditions in the network can be accurately and reliably recorded. When the existing area is not covered by the cell, the terminal can also record such an abnormal situation and report it to the network, thereby avoiding the problem of inaccurate cell failure by relying solely on telecommunication statistics. . In addition, by recording the abnormal information of the network and reporting it to the network, the abnormality of the network fault can be found at any time, so that the fault can be randomly determined and solved, and the shortcoming of the network fault feedback in the prior art is avoided.

While the invention has been illustrated and described with reference to the preferred embodiments embodiments The spirit and scope of the invention.
