At present, when a terminal device communicates with a network device, an abnormal communication event may occur between the terminal device and the network device. In order to optimize the network, it is generally necessary to collect relevant data of the abnormal communication.

In the related art, network operators or network optimization service providers usually need to use dedicated terminal equipment software to collect information on communication anomalies.

However, the related art method of collecting information on the site of communication anomalies is inefficient.

Summary of the invention

The present application provides a communication method and apparatus, which can improve the efficiency of collecting information when communication between a terminal device and a network device is abnormal.

In a first aspect, an embodiment of the present application provides a communication method, including:

Obtain target information, the target information includes information related to a target event, the target event includes an event of abnormal communication between a terminal device and a network device, and send the target information to a target network device.

Optionally, the method may be executed by a terminal device or by a chip in the terminal device.

In the embodiment of the present application, information related to the communication abnormality event is obtained through the terminal device, and information related to the communication abnormality event is sent to the target network device. In this way, information when the communication abnormality between the terminal device and the network device occurs can be collected through information interaction between the terminal device and the network device, thereby improving the efficiency of collecting information when the communication abnormality between the terminal device and the network device occurs.

In a possible implementation manner, the information of the terminal device includes at least one of a first cell identifier, a tracking area code TAC, a public land mobile network identifier PLMN, a geographic location, or a time.

In the embodiment of the present application, the information of the terminal device may include at least one of the first cell identifier, the tracking area code TAC, the public land mobile network identifier PLMN, the geographic location or the time, and the more information the terminal device has, the more information is sent to the network device. In this way, when the network device needs to use the target information sent by the terminal device to optimize the network, the parameters based on the network optimization can also be improved, thereby improving the effect of network optimization, and further improving the communication quality between the terminal device and the network device.

In a possible implementation, the communication abnormality event includes at least one of the following:

The radio resource control (RRC) connection establishment is rejected during the registration or service request process.

In this way, the network device can learn about the occurrence of the target event. Optionally, when the network device uses the target information for network optimization, it can be optimized according to the occurrence of different events. For example, select a target event with a higher number of occurrences, or select a target event with a higher frequency of occurrence, or select an event with a higher frequency of occurrence according to the target level for network optimization, or select a cell with a higher number of occurrences of the target event, or select a cell with a higher frequency of occurrence of the target event for network optimization.

2. Cell: A cell, also known as a cellular cell, refers to the area covered by a base station or a part of a base station (sector antenna) in a cellular mobile communication system. In this area, a mobile station can communicate reliably with the base station through a wireless channel.

3. Tracking area (TA): TA is an important concept in the LTE system and is used for UE location management. When a UE is in an idle state, the core network is able to know the tracking area where the UE is located.

When the UE moves within the TA list, there is no need to perform a TA update to reduce frequent interactions with the network. However, when the UE enters a new TA area that is not in its registered TA List, a TA update needs to be performed, and a set of TAs will be reallocated to the UE.

Optionally, the information related to the target event includes, but is not limited to, the information of the terminal device when the target event occurs, such as the location information and time information of the terminal device. The information related to the target event may also include network information between the terminal device and the network device, such as the first cell identifier, tracking area code (TAC) or public land mobile network identifier PLMN.

Among them, the first cell identifier may refer to the identifier of the first cell, which is used to indicate the first cell. The first cell may refer to the cell to which the terminal device accesses when an abnormal communication event occurs between the terminal device and the network device. The tracking area code TAC may refer to the code of the tracking area, which is used to indicate the tracking area. The tracking area may refer to the tracking area where the terminal device is located when an abnormal communication event occurs between the terminal device and the network device. The public land mobile network identifier PLMN may refer to the PLMN when an abnormal communication event occurs between the terminal device and the network device. The PLMN of the embodiment of the present application can be used to indicate the operator of the cell to which the terminal device accesses when an abnormal communication event occurs between the terminal device and the network device. The geographical location may indicate the location of the terminal device when an abnormal communication event occurs between the terminal device and the network device. The time may indicate when the abnormal communication event between the terminal device and the network device occurs.

It should be understood that the first cell does not specifically refer to a specific cell, but rather a cell to which the terminal device accesses when an abnormal communication event occurs between the terminal device and the network device. That is, there may be one or more first cells.

In a possible implementation, a method for determining whether an abnormal communication event occurs between the terminal device and the network device may include: using the first cell to send a second request to the network device, the second request being used to request registration or to request establishment of a service. If no response to the second request is received from the network device within the first time period, it may be considered that the first cell is abnormal, that is, an abnormal communication event occurs between the terminal device and the network device, and the target information may be obtained at this time.

In another possible implementation, if no response to the second request is received from the network device within the first time period, a third request is sent to the network device using the second cell, and the third request is used to request registration or to request service establishment. If a response to the third request is received from the network device within the second time period, it means that the abnormal communication event is not caused by the terminal device itself, but is caused by an abnormality in the first cell, and the target information can be obtained at this time. In this way, the accuracy of determining whether the communication abnormality is caused by the cell to which the terminal device is connected can be improved.

Optionally, if it is determined that the communication anomaly is caused by the anomaly of the first cell, the first cell is disabled for a third time period, and during the disabled time period, the terminal device no longer accesses the first cell.

It should be noted that the third duration may be a fixed duration or a third duration dynamically set according to actual conditions, and is not limited here.

Exemplarily, when the third duration is dynamically set, it can be determined according to the number or frequency of communication anomalies in the first cell. For example, the higher the number or frequency of communication anomalies in the first cell, the longer the third duration, that is, the third duration is positively correlated with the number or frequency of communication anomalies in the first cell.

In a possible implementation, the first time period may be disabled only when the number of communication anomalies of the first cell exceeds a number threshold, or the frequency exceeds a frequency threshold. In this way, the situation of mistakenly disabling cells caused by occasional communication anomalies due to network jitter can be reduced.

S220. The terminal device sends target information to the target network device.

In an embodiment of the present application, target information is sent to a target network device, and the network device can obtain information of the terminal device at the time of the target event.

It should be noted that the network device corresponding to the event of communication anomaly and the target network device sent by the terminal device may be the same or different network devices. Exemplarily, it may be an event of communication anomaly between the terminal device and network device 1, and the target information is sent to network device 1. It may also be an event of communication anomaly between the terminal device and network device 1, and the target information is sent to network device 2. Optionally, the target network device may be the network device to which the terminal device sends the target information and to which the cell to which the terminal device accesses is located. In addition, the event of communication anomaly may be an event related to one or more network devices. Exemplarily, the terminal device may send an event of communication anomaly between the terminal device and network device 1, or may send an event of communication anomaly between the terminal device and network device 1, and between the terminal device and network device 3, without limitation here.

The technical solution of the embodiment of the present application obtains information when a communication abnormality occurs between a terminal device and a network device through a terminal device, and sends the information when the communication abnormality occurs to a target network device. In this way, information when a communication abnormality occurs between the terminal device and the network device can be collected through information interaction between the terminal device and the network device, thereby improving the efficiency of collecting information when a communication abnormality occurs between the terminal device and the network device.

Optionally, the network device can use the target information to perform network optimization processing. The network optimization processing of the embodiment of the present application may include but is not limited to one or more optimizations of network coverage optimization, user perception improvement, switching optimization, capacity planning or troubleshooting. Among them, network coverage optimization can determine which areas have insufficient or excessive network coverage by analyzing the collected signal strength data, thereby adjusting base station parameters, optimizing network layout, and improving network coverage quality. User perception improvement can understand the user's perception during network use by analyzing the data reported by the user device, including signal quality, data transmission speed, etc. This helps to discover problems in the network and make adjustments in a timely manner to improve user satisfaction. Switching optimization can optimize switching strategies, reduce switching failures and dropped calls, and improve network stability by analyzing the switching data of the user device between different base stations. Capacity planning can understand the network's traffic usage by collecting the traffic data generated by the user device, and provide data support for future network capacity planning. Troubleshooting can mean that when a network fails, the problem can be quickly located by analyzing the data reported by the user device, and troubleshooting and repair can be performed in a timely manner. In general, after receiving the target information, the network device can use the target information to optimize the network and improve user perception to provide better network services.

In a possible implementation manner, the information related to the target event includes a first cell identifier, and performing network optimization processing based on the target information includes:

Disable the first cell for the fourth duration.

In the embodiment of the present application, if the first cell is a cell managed by the target network device, the target network device directly disables the first cell. If the first cell is not a cell managed by the target network device, the target network device notifies the network device managing the first cell to disable the first cell.

Optionally, the fourth duration may be fixed or dynamically adjusted.

A possible way to dynamically adjust the fourth duration may be to set the fourth duration by the number or frequency of target events occurring in the cell. For example, the greater the number or the higher the frequency, the greater the fourth duration. That is, the number or the frequency of target events occurring in the cell is positively correlated with the fourth duration. In this way, the longer the cell ban time is for cells with higher number or frequency of communication anomalies, the fewer cases of terminal devices accessing cells with higher number or frequency of communication anomalies, thereby improving the success rate between the terminal device and the network device. In addition, since the target network device can obtain the target information of one or more terminal devices, the target network device can use the target information of multiple terminal devices for comprehensive evaluation, thereby improving the accuracy of network optimization processing.

In a possible implementation manner, the information related to the target event includes at least one of a target frequency, a target number of times, or a target level.

The target frequency indicates the number of occurrences of the target event in the first time period, or indicates the number of occurrences of the target event in each first cell in the first time period.

The target number indicates the number of occurrences of the target event, or indicates the number of occurrences of the target event in each first cell.

The target level indicates the frequency level of occurrence of the target event, or indicates the frequency level of occurrence of the target event in each first cell.

The frequency level may be that the higher the level, the higher the frequency of occurrence. In other words, the lower the level, the lower the frequency of occurrence. Alternatively, the higher the frequency level, the lower the frequency of occurrence. In other words, the lower the frequency level, the higher the frequency of occurrence.

Optionally, the information of the target event may be statistically analyzed periodically. For example, the second time period is a period. The second time period may be one hour or one day, and may be set as required, without limitation.

It should be understood that when the terminal device sends the target information, it can send the target number, target frequency or target level, so that the network device can know the occurrence of the target event. Optionally, the network device can optimize the network for the target event with the highest number of occurrences or the highest frequency, or optimize the network for the cell with the highest number of occurrences or the highest frequency of the target event.

It should be noted that, in one possible implementation, the target number, target frequency or target level may be sent by default, that is, each time the target information is sent to the target network device, the target number, target frequency or target level is sent by default, so that each time the target information is sent, the target network device can obtain the occurrence of the target event, which can improve the richness of the information sent by the terminal device. In another possible implementation, the information of the target event may be carried in the target information when an instruction is received, so that the target number, target frequency or target level can be sent when needed, and when the target event information does not need to be sent, the data volume of the target information can be reduced, so that the channel resources required to send the target information can be reduced.

In a possible implementation, the terminal device may send information about each event in all target events to the target network device, so that the target network device can fully understand the target events that have occurred. Exemplarily, the target events include event 1 and event 2, and the terminal device records information about the terminal device when event 1 occurs, and information about the terminal device when event 2 occurs. The terminal device may send information about the terminal device when event 1 occurs, and information about the terminal device when event 2 occurs.

In a possible implementation, the target event is an event whose occurrence number is greater than a first threshold, or an event whose occurrence frequency is greater than a second threshold. Alternatively, the first cell is a cell whose occurrence number of the target event is greater than a third threshold, or the first cell is a cell whose occurrence frequency of the target event is greater than a fourth threshold.

In an embodiment of the present application, the network device may select a target event that occurs more frequently, or select a target event with a higher target frequency for transmission, or select a cell where a target event occurs more frequently/with a higher frequency for transmission. In this way, the target information transmitted may include some events among all communication abnormality events, or some cells among all cells with communication abnormalities, thereby saving the channel resources required for the target information sent by the terminal device.

Exemplarily, the target event includes event 1 and event 2, and the terminal device records the information of the terminal device when event 1 occurs, and the information of the terminal device when event 2 occurs. Assuming that event 1 occurs 10 times and event 2 occurs 1 time, the number of occurrences of event 1 is greater than the second threshold, and the number of occurrences of event 2 is less than the second threshold, then the terminal device can send the information of the terminal device when event 1 occurs, but not send the information of the terminal device when event 2 occurs. As another example, the first cell includes the first cell 1 and the first cell 2. Assuming that the total number of target events occurring in the first cell 1 is 10 times, and the total number of target events occurring in the first cell 2 is 1 time, the reported information includes the identifier of the first cell 1, but does not include the identifier of the first cell 2.

It should be understood that the number of times the target event occurs in each cell can be counted individually or cumulatively, and there is no limitation here. One example of individual counting can be that the number of times event 1 occurs in the first cell 1 is 8 times, and the number of times event 2 occurs in the first cell 2 is 2 times.

It should be noted that in a possible implementation, the terminal device may actively send the target information, for example, the terminal device actively sends the target information when the sending conditions are met. For example, the sending conditions may include but are not limited to reaching the sending time, detecting the target event, the number of occurrences of the target event being greater than the number threshold, the frequency of occurrence of the target event being greater than the frequency threshold, etc., the number of times the target event occurs in the cell being greater than the number threshold, the frequency of occurrence of the target event in the cell being greater than the frequency threshold, etc., without limitation here, so that the terminal device can send the target information when the target event occurs in a timely manner.

In another possible implementation manner, the terminal device may also send information based on a request from the target network device.

Please refer to Figure 3, which is a flow chart of another communication method provided in an embodiment of the present application. The method of the embodiment of the present application is based on the situation where the terminal device responds to the request of the network device to send the target information. The communication method shown in Figure 3 may include:

S310. The target network device sends a first request to the terminal device, where the first request is used to request sending target information.

S320. The terminal device sends target information to the target network device in response to the first request.

In the embodiment of the present application, the relevant content of how to send target information to the target network device can refer to the description of the above embodiment and will not be repeated here.

In an embodiment of the present application, by sending target information to the target network device in response to a first request from the target network device, the target information can be sent to the network device in a directionally manner and the flexibility of sending the target information can be improved. In addition, optionally, the target network device can send the first request to the terminal device when its resource idle rate is high, such as when the channel resource idle rate is high or the computing power resource idle rate is high, so that the utilization efficiency of resources can be improved.

In a possible implementation, the first request includes information indicating the first time period. That is, the target network device may instruct the terminal device to send target information within the first time period, and the target information sent by the terminal device is information within the first time period.

Exemplarily, the terminal device records the terminal device information when the target event occurs at 9:00, the terminal device information when the target event occurs at 10:00, and the terminal device information when the target event occurs at 11:00. The first request can indicate 9:00-10:00, then the target information sent by the terminal device is the target information within 9:00 and 10:00.

In an embodiment of the present application, the target network device can request the terminal device to send information about the target event within a specific time period. The terminal device responds to its request and sends information within a first time period to the target network device. In this way, the information of the time period to be sent can be selected according to actual conditions, thereby improving the flexibility of collecting information on communication abnormal events and saving channel resources between the terminal device and the network device.

In a possible implementation, the first request includes an instruction to send information of the target event. When the first request received by the terminal device includes an instruction to send information of the target event, the target information sent by the terminal device includes the information of the target event.

It should be understood that if the first request includes information indicating the first time period and an indication of sending information about the target event, the target information reported by the terminal device may not include time. In this way, the network device can roughly determine the number of occurrences or frequency of the target event within the first time period based on the information about the first time period and the target event, and can also reduce the channel resources required to send the target information between the terminal device and the network device.

In addition, if the target information includes time, the first request sent by the network device may not include information indicating the first time period and an indication of sending target event information. The network device can also determine the number of occurrences or frequency of the target event based on time.

Please refer to Table 1 and Table 2 respectively. Table 1 and Table 2 are schematic diagrams of target information provided in the embodiments of the present application.

Table 1

As shown in Table 1, the target information includes an indication of the target event, such as "Event 1", "Event 2", etc., and for example, indications such as "1", "2", etc., then the target information at this time can indicate that when Event 1 occurs in the terminal device, the information recorded is Cell ID 1, TAC1, PLMN1, Geographic Location 1 and Time 1, and Cell ID 2, TAC2, PLMN2, Geographic Location 1 and Time 2. When Event 2 occurs in the terminal device, the information recorded is Cell ID 3, TAC3, PLMN3, Geographic Location 3 and Time 3, and Cell ID 4, TAC4, PLMN4, Geographic Location 3 and Time 4.

As shown in the example of target information in Table 1, the specific event associated with the information of the terminal device can be more refined, thereby providing the network device with more accurate event information.

Table 2

As shown in Table 2, it can be known that the information recorded when the target event occurs is cell identifier 1, TAC1, PLMN1, geographic location 1 and time 1, cell identifier 2, TAC2, PLMN2, geographic location 1 and time 2, cell identifier 3, TAC3, PLMN3, geographic location 3 and time 3, and cell identifier 4, TAC4, PLMN4, geographic location 3 and time 4. Compared with Table 1, Table 2 can reduce the indication of the target event, which can reduce the channel resources required to send the target information.

In the target information shown in Table 2, when there are multiple target events, a field can be reserved for each target event, and the target event corresponding to the terminal device information can be known based on the field where the terminal device information is located.

In a possible implementation, the first request may include information indicating the target event. Exemplarily, assuming that the target event includes events such as RRC connection establishment rejection, RRC connection establishment no response, RRC connection establishment early release, and data radio bearer resource DRB not established, the first request may request the terminal device to report at least one target event when the terminal device information occurs, such as requesting the terminal device to send the information of the terminal device when the RRC connection establishment rejection and RRC connection establishment no response events occur, and for example, requesting the information of the terminal device when the RRC connection establishment rejection occurs, which is not limited here.

Exemplarily, in combination with Table 1, assuming that the target event includes event 1 and event 2, if the first request includes information indicating event 1 but does not include information indicating event 2, the target information sent by the terminal device may be as shown in Table 3.

table 3

In an embodiment of the present application, the network device can request the terminal device to send information about the terminal device when one or more target events occur, as well as information about each of the one or more target events. In this way, the terminal device can be selectively allowed to send information about the terminal device when one or more target events occur, as well as information about each of the one or more target events, based on actual conditions. This can improve the flexibility of collecting information about communication anomalies.

Please refer to FIG. 4, which is a flow chart of another communication method provided in an embodiment of the present application. This embodiment is described with MDT message interaction. The method shown in FIG. 4 may include:

S410: The target network device sends an information request to the terminal device.

S420. The terminal device sends an information response message to the target network device.

In this embodiment, the target information is carried in the information response message. The information response message can also be called the terminal device information response.

In the embodiment of the present application, the first request and the target information may refer to the description of the above embodiment and will not be elaborated here.

Optionally, the information request may further include the flag information of the first request. The flag information of the first request may be used to indicate whether the target information needs to be reported. Exemplarily, if the flag information of the first request is the first flag, the target information is sent. If the flag information of the first request is the second flag, the target information is not sent. The first flag may be, for example, "true", and the second flag may be, for example, "false", or the first flag may be, for example, "1", and the second flag may be, for example, "0". Alternatively, the first flag may be, for example, "0", and the second flag may be, for example, "1", which is not limited here.

Optionally, the information request may further include a fourth request. The fourth request may refer to a request other than the first request. For example, the fourth request may be used to request the provision of movement history information. In this way, one information request may carry multiple requests and request multiple information simultaneously.

Optionally, the information request may further include flag information of a fourth request. The flag information of the fourth request may refer to the description of the flag information above, which will not be described in detail here.

In the embodiment of the present application, the terminal can also be selectively requested to provide one or more types of information through the flag information of each request, thereby improving the convenience of information request.

In a possible implementation, the information response message includes a first field, a second field, a third field, a fourth field, a fifth field, and a sixth field.

The first field is used to carry the first cell identifier.

The second field is used to carry the Tracking Area Code TAC.

The third field is used to carry the public land mobile network identity PLMN.

The fourth field is used to carry the geographic location.

The fifth field is used to carry time.

The sixth field is used to carry information about the target event.

It should be noted that the first field, the second field, the third field, the fourth field, the fifth field and the sixth field may be fields shared with other information or may be fields used independently, and there is no limitation here.

It should be understood that sharing fields with other information can reduce the data size of the information response message, while using fields alone can reduce field conflicts.
