The number of core network devices, access network devices, and terminal devices included in the communication system 100 is not limited in the embodiment of the present application.
Optionally, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the embodiment of the present application is not limited thereto.
It should be understood that the communication system 100 shown in fig. 1 is merely an example, and the present application is not limited to the specific architecture of the system to which the present application is applied nor to the number and form of the various devices included in each communication system. For example, the number of neighbor cells of the serving cell to which the terminal device is currently connected may be greater, and the neighbor cells of the serving cell and the serving cell may belong to cells covered by the same access network device, or may also respectively belong to cells covered by different access network devices.
Some technical terms related to the present application are described below.
1. A cell (cell) is described from the point of view of resource management or mobility management or service units. The coverage area of each access network device may be divided into one or more cells and the cells may be regarded as being made up of certain frequency domain resources. A cell may be an area within the coverage of a wireless network of an access network device. In the embodiment of the application, different cells can correspond to different access network devices. For example, the access network device to which cell #1 belongs and the access network device to which cell #2 belongs may be different access network devices, such as base stations. That is, cell #1 and cell #2 may be managed by different base stations, in which case it may be referred to as co-sited, or co-sited, with cell #1 and cell # 2. The access network device to which the cell #1 belongs and the access network device to which the cell #2 belongs may also be different radio frequency processing units of the same base station, for example, a remote radio unit (radio remote unit, RRU), that is, the cell #1 and the cell #2 may be managed by the same base station, have the same baseband processing unit and intermediate frequency processing unit, but have different radio frequency processing units. The present application is not particularly limited thereto.
Cell handover refers to handover that is required in order to maintain uninterrupted communication of a terminal device when the terminal device moves from one cell to another in a wireless communication system.
2. Tracking area codes (TRACKING AREA codes, TACs), representing the geographical location codes of cells, may be used to distinguish between different tracking areas. A tracking area is a set of a plurality of neighboring cells between which a terminal device can handover. Illustratively, the TAC may be a 16-bit identifier for uniquely identifying a tracking area.
3. A public land mobile network (public land mobile network, PLMN), which is a concept of a mobile communication network, is used to represent the entire mobile communication network of one operator. A PLMN consists of a plurality of cells, each belonging to a specific PLMN. The PLMN includes base stations, core networks and other network equipment for providing mobile communication services. Also, the PLMN may include a plurality of tracking areas, each of which may correspond to one TAC.
4. Minimization DRIVE TEST (MDT): and an automatic drive test technology for acquiring, reporting and preprocessing measurement data by configuring terminal equipment through a network. The terminal device starts a global positioning system (global positioning system, GPS) and supports an MDT function, and the terminal device automatically reports MDT data containing user position information to the network device. The MDT data may be used for big data analysis.
It should be noted that, hereinafter, signaling interaction between the terminal device and the network device may also be understood as signaling interaction between the terminal device and the access network device. The network optimization may be an optimization of anomalies at the core network level, which will not be described in detail in the following for the sake of brevity.
In the registration process or the service establishment process, registration failure or service establishment failure may be caused due to abnormal core network layer level and other reasons. For example, the terminal device sends a registration request to the network device (registration request); the network device does not respond or sends a message for rejecting the registration request to the terminal device. Also for example, the terminal device sends a Service Request (SR) to the network device; the network device does not respond or sends a message to the terminal device for rejecting the service request. Therefore, network abnormality occurs in the terminal equipment, normal operation of the service of the terminal equipment is affected, and the user experience is poor.
Therefore, it is needed to provide a method, which can facilitate the network device to determine the reason and the position of the abnormality and facilitate the network optimization under the condition of the abnormality of the core network layer, so as to help to improve the success rate of registering or establishing the service of the terminal device and improve the user experience.
In view of this, the present application provides a communication method in which, in the case where a terminal device determines that a registration failure or a service establishment failure has occurred, the terminal device can determine location information of the terminal device, such as a cell identity, TAC, PLMN, etc., at the time of the registration failure or the service establishment failure and transmit the location information to a network device. In this way, the network device can combine the location information and the running log of the network device to determine the information such as the reason of the abnormality and the location where the abnormality frequently occurs, thereby facilitating the subsequent network optimization, being beneficial to improving the success rate of registering or establishing the service of the terminal device and improving the user experience.
The communication method of the present application will be described in detail with reference to fig. 2 to 4. The embodiment of the application shows the communication method provided by the application from the perspective of device interaction. The specific form and number of the devices shown therein are only examples and should not be construed as limiting the practice of the method provided by the present application in any way. The communication method according to the embodiment of the present application will be described in detail below by taking a terminal device and a network device as an execution subject.
It should be understood that the terminal device may be the terminal device itself, a chip system or a processor supporting the terminal device to implement a communication method, or a logic module or software capable of implementing all or part of the terminal device; the network device may be the network device itself, a chip system or a processor for supporting the network device to implement a communication method, or a logic module or software capable of implementing all or part of the network device, which is not limited in detail.
Fig. 2 is a flow chart of a communication method 200 according to an embodiment of the present application. The method 200 may be applied to the system 100. As shown in fig. 2, the method 200 includes the steps of:
S201, the terminal equipment sends second information to the network equipment, wherein the second information is used for requesting registration or for requesting establishment of service. Correspondingly, the network device receives the second information from the terminal device.
In the case where the second information is used to request registration, the second information may be, for example, a registration request, or may also be signaling sent by other terminal devices in the registration procedure to the network device, which is not specifically limited in the present application.
In the case where the second information is used to request to establish a service, the second information may be, for example, a Service Request (SR), or the second information may also be signaling sent by other terminal devices in the service request flow (service request procedure) to the network device, which is not specifically limited in the present application.
S202, the terminal equipment determines first information, wherein the first information comprises position information and information for indicating a first event, the first event comprises registration failure and/or service establishment failure, the position information is used for indicating the position of the terminal equipment when the first event occurs, and the information for indicating the first event is used for indicating the frequency of the first event at the position.
Wherein the location information may include information indicating one or more locations. Illustratively, the location information includes information for indicating location 1 and information for indicating location 2. Or the location information may comprise, for example, cell identities of one or more cells and/or identities for indicating one or more beams, etc.
The information indicating the first event may include information indicating how frequently the first event occurs at each of the one or more locations. Illustratively, the location information is used to indicate location 1 and location 2. The information indicating the first event may include information a and information b. The information a is used for indicating the frequency of the first event at the position 1, and the information b is used for indicating the frequency of the first event at the position 2.
Alternatively, S202 may be implemented by: and determining the first information under the condition that the response from the network equipment to the second information is not received in the second time period.
In this way, in the case where the terminal device does not receive a response from the network device, the terminal device may determine that registration has failed or that service establishment has failed, and the terminal device may determine where the terminal device is located.
The terminal device may determine that no response from the network device to the second information is received within the second time period by: after S201, the terminal device starts a first timer, and before the first timer expires, the terminal device does not receive a response from the network device to the second information. In this way, the terminal device may determine that the first event occurs based on the timer expiration.
S203, the terminal equipment sends the first information to the network equipment. Correspondingly, the network device receives the first information from the terminal device.
In the communication method of the application, under the condition that the terminal equipment determines the information of the registration failure or the service establishment failure, the terminal equipment can determine the position of the terminal equipment and the frequency of the registration failure or the service establishment failure at the position. In this way, the terminal device can send information for indicating the location where the terminal device is located and the frequency of registration failure or service establishment failure of the location to the network device, so that the network device can determine the reasons of the abnormality and the locations where the abnormality frequently occurs based on the information from the terminal device, thereby facilitating the subsequent network optimization, being beneficial to improving the success rate of registration or establishment of the service of the terminal device and improving the user experience.
First, information included in the first information will be described in detail.
As an alternative embodiment, the location information includes one or more of the following: cell identity, first TAC, public land mobile network identity or geographical location information.
The cell identity may also be referred to as a cell ID or the like, and can be used to distinguish between different cells. The TAC may be configured to distinguish between different tracking areas, and the first TAC may instruct the terminal device to determine the tracking area in which the terminal device is located when the first event occurs. Public land mobile network identities, which may also be referred to as PLMN IDs or the like, can be used to distinguish between different mobile network operators. The PLMN ID may also include a mobile country code (mobile country code, MCC) and a mobile network code (mobile network code, MNC). The MCC may be used to identify a country or region and the MNC may be used to identify a mobile network operator. The geographical location information may be information such as coordinates. The geographic location information may be, for example, specific coordinates of a location. Or the geographical position information may be information indicating a part of the area, for example, latitude and longitude ranges, and may be a beam or the like.
It should be appreciated that the cell identity, the first TAC, the public land mobile network identity or the geographical location information can be used to indicate the location or area in which the terminal device is located. In this way, the network device is assisted in determining where the anomaly occurred, such as the cell, TAC, PLMN, or geographic location where the anomaly occurred, etc. Or the network device can be enabled to determine a location or an area where the occurrence frequency of the anomaly is high, for example, a cell or a tracking area where the occurrence frequency of the anomaly is highest, etc. And the subsequent network optimization of the abnormal frequent position or the abnormal serious position is facilitated.
In an example, the network device may determine that there is an anomaly at the first geographic location if the network device determines, based on the location information and the information indicating the first event, that the terminal device is more frequent in the vicinity of the first geographic location in cell a. Since the first event does not occur in a position other than the first geographic position in the cell a, which indicates that the access network device corresponding to the cell a is not abnormal, the abnormal cause may be that the channel quality near the first geographic position is poor due to shielding or interference and the like near the first geographic position.
In another example, if the network device determines, according to the location information, that the frequency of occurrence of the first event is higher in the TACs or cells corresponding to the same PLMN, it may be determined that the network device corresponding to the PLMN may have an anomaly.
Alternatively, the network device may determine the cause of the abnormality and the location where the abnormality occurs in conjunction with the first information and the operation log of the network device.
It should be understood that the log of the operation of the network device may have detailed information recorded therein that the network device is operating when the anomaly occurred. The network device can determine the position where the abnormality occurs based on the position information, and can also determine the frequency of the first event occurring at the position by combining the information for indicating the first event, and the success rate of determining the cause of the abnormality and the abnormal position by combining the operation log of the network device is improved.
Based on the above embodiments, the information type included in the location information may be protocol conventions or configured by the network device through signaling. In this way, the terminal device can determine the specific content included in the reported location information. The network device configures, by signaling, that the location information includes a cell identifier and a TAC, and the location information reported by the terminal device includes the cell identifier and the TAC of the cell in which the first event occurs.
Illustratively, the method 200 further includes: the network device sends information 1 to the terminal device, where the information 1 is used to indicate the information type included in the location information. Correspondingly, the terminal device receives information 1 from the network device. In this way, the network device can indicate the granularity of the position information to the terminal device according to the requirement, so that the network device has higher flexibility in acquiring the position information.
As an alternative embodiment, the first information further comprises information indicating the moment of occurrence of the first event. In this way, the network device can determine a point in time at which an abnormality occurs based on the time indicated by the first information; or the network equipment can also query and obtain the content in the operation log corresponding to the moment from the operation log based on the moment indicated by the first information, so that the network equipment can conveniently determine the reason of the abnormality by combining the operation log.
The time when the first event occurs may be a time when the terminal device determines that no response from the network device to the second information is received in the second duration, for example, a time when the first timer expires, or the like.
In the following, description will be made taking, as an example, the first information including position information, information indicating the first event, and information indicating the time when the first event occurs. In some possible embodiments, the first information does not include information indicating a time when the first event occurs, and the terminal device determines a location where the terminal device is located and a number, frequency, or level of occurrence of the first event at the location when it is determined that the first event occurs. For brevity, the description will not be repeated below for the case where the first information does not include information for indicating the time when the first event occurs.
The information indicating the first event may be information indicating the time when the first event occurs. I.e. the terminal device determines a moment each time it determines that a first event has occurred. Correspondingly, the information for indicating the first event may include at least one time, and the at least one time corresponds one-to-one with the at least one location indicated by the location information.
In this way, the network device may count the number of times the first event occurs in each of the at least one location according to the information for indicating the first event, or may determine the time when the first event occurs each time according to the information for indicating the first event.
As an alternative embodiment, the first information comprises information determined during the first time period. Or it may be understood that the information included in the first information is information related to a first event occurring within the first time period. I.e. the occurrence moments of the first events indicated by the first information all belong to the first time period.
The location information in the first information is used to indicate a third cell and a fourth cell, where the information corresponding to the third cell and used to indicate the first event is N1 times, and the information corresponding to the fourth cell and used to indicate the first event is N2 times. Then N1 times the first event in the third cell and N2 times the first event in the fourth cell occur within the first time period. N1 and N2 are positive integers.
By the scheme, the network equipment can acquire the first information in the specific time period, so that the network equipment can conveniently determine the abnormal position and the abnormal reason in the specific time period.
On the basis of the above embodiment, optionally, the first period is configured by protocol convention or by signaling by the network device. In this way, the terminal device can determine the first time period, and buffer the position, the occurrence time, the occurrence times and the like of the terminal device when the first event occurs in the first time period.
Under the condition that the first time period is the protocol agreement, the network equipment does not need to be configured through signaling, so that the signaling overhead is smaller. The network device is configured through signaling at the first time, and the network device can configure a plurality of different time periods, so that the flexibility of configuring the first time period is higher.
Illustratively, the method 200 further includes: the network device sends information 2 to the terminal device, the information 2 being used to indicate the first time period. Correspondingly, the terminal device receives information 2 from the network device.
As an alternative embodiment, the information for indicating the first event includes one or more of the following: the first frequency, the first number of times or the first level, the first frequency representing the number of occurrences of the first event within the first duration, the first number of times representing the number of occurrences of the first event, and the first level representing the frequent level of occurrence of the first event.
In this way, the network device can determine the frequency of the first event at each cell, each TAC, each PLMN or each geographic location, so as to facilitate the network device to determine the location where the abnormality occurs frequently.
The first duration may be a preset duration or a time period. Such as 2 hours, 10 hours, 48 hours, etc.; or 10:00 to 18:00, etc. And, the first duration may be configured by the network device, or may be a protocol contract. Illustratively, the method 200 further includes: the network device sends information indicating the first duration to the terminal device. Correspondingly, the terminal device may receive information from the network device indicating the first duration. In this way, the network device may obtain the frequency at which each location transmits the first event for a particular duration.
It is understood that the first frequency may be determined based on the first time period and the number of times the first event occurs within the first time period. Illustratively, the first frequency is equal to a ratio of a number of first events to a first duration.
The first level may be determined from a set of preset levels according to a first frequency or a first number of times. Illustratively, the preset level set includes level 1, level 2, and the like 3. Wherein, level 1 is more frequent than the first event indicated by level 2; level 2 is more frequent than the first event indicated by level 3. The first rank may be rank 1 in the case where the first frequency is greater than or equal to a first threshold, or the first number of times is greater than or equal to a second threshold; in the case where the first frequency is greater than or equal to the third threshold and less than the fourth threshold, or the first number is greater than or equal to the fifth threshold and less than the sixth threshold, the first level may be level 2, the first threshold is greater than or equal to the fourth threshold, and the second threshold is greater than or equal to the sixth threshold; in the case where the first frequency is less than or equal to a seventh threshold, or the first number of times is less than or equal to an eighth threshold, the first level may be level 3, the seventh threshold is less than or equal to the third threshold, and the eighth threshold is less than or equal to the fifth threshold.
One or more of the preset level set, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold or the eighth threshold can be agreed by the network device through signaling configuration or protocol.
In the above embodiment, the description is given by taking the example that the preset level set includes three levels. In some possible embodiments, the preset level set may include more or less levels, and in the case that the preset level set includes more or less levels, the levels are classified in a similar manner to the three levels described above, and reference is made to the above description, which is not repeated herein.
It should be appreciated that the location information in the first information is used to indicate one or more locations and the information used to indicate the first event is used to indicate how frequently the first event occurred at each of the one or more locations. Thus, each of the one or more locations corresponds to one or more of a first frequency, a first number of times, or a first level. Wherein the one or more locations may refer to one or more cells, one or more tracking areas, or one or more PLMNs, etc.
In one example, the location information includes: cell identity 1, TAC 1 and PLMN ID 1; cell identity 2, TAC 2 and PLMN ID 2. Wherein, cell identity 1, TAC 1 and PLMN ID 1 are used to indicate the first cell. Cell identity 2, TAC 2 and PLMN ID 2 coordinate 2 are used to indicate the second cell. The cell identifier 1, the TAC 1 and the PLMN ID 1 may correspond to the number a, which indicates that the first event occurs a times in the first cell altogether; the cell identity 1, TAC 1 and PLMN ID 1 may correspond to a number B, indicating that the second cell co-occurs B times the first event. A and B are positive integers.
In another example, the location information includes: TAC 1 and PLMN ID 1; TAC 2 and PLMN ID 1. Wherein TAC 1 and PLMN ID 1 are used to indicate the first tracking area. TAC 2 and PLMN ID 1 are used to indicate a second tracking area. TAC 1 and PLMN ID 1 may correspond to number C, indicating that the first tracking area co-occurs for C first events; TAC 2 and PLMN ID 1 may correspond to a number D, indicating that the second tracking area co-occurs D times the first event. C and D are positive integers.
On the basis of the above embodiment, optionally, the information for indicating the first event satisfies one or several of the following: the first times are larger than or equal to a first preset threshold value; the first frequency is greater than or equal to a second preset threshold; or, the first level is higher than or equal to the first preset level.
Or may also be understood as: the first information reported by the terminal equipment comprises one or more of the following items: the number of occurrences of the first event is greater than or equal to a first preset threshold and the time of occurrence of the first event, the frequency of occurrence of the first event is greater than or equal to a second preset threshold and the time of occurrence of the first event or the frequency of occurrence of the first event is greater than or equal to a first preset level and the time of occurrence of the first event.
The first preset threshold value and the second preset threshold value are positive numbers. For example, the first preset threshold may be 3 times, and the terminal device may report the cell identifier, TAC, PLMN ID, and the like corresponding to the cell with the occurrence number of the first event greater than or equal to 3 times. The second preset threshold may be, for example, 0.5/h, and the terminal device may report, for each two hours, a cell identifier, TAC, PLMN ID, and the like corresponding to a cell in which the number of occurrences of the first event is greater than or equal to 1. The first preset level may be level 3 or more severe, etc. The first preset level may be one of a set of preset levels.
Alternatively, one or more of the first preset threshold, the second preset threshold, or the first preset level may be configured for protocol conventions or by signaling by the network device. In this way, the terminal device can determine that the location information and the information for indicating the first event need to be reported.
Illustratively, the method 200 further includes: the network device sends information 3 to the terminal device, where the information 3 is used to indicate one or more of the first preset threshold, the second preset threshold, or the first preset level. Correspondingly, the terminal device receives information 3 from the network device. In this way, the network device can determine the position with higher frequency of occurrence of the first event, thereby determining the corresponding abnormality cause, so that the network device can perform network optimization on the abnormality position with higher severity.
Next, a manner in which the network device acquires the first information will be described in detail.
As an alternative embodiment, prior to S203, the method 200 further includes: the network device sends a first request to the terminal device, and correspondingly, the terminal device receives the first request from the network device. S203 may be implemented by: in response to the first request, the terminal device sends first information to the network device, and correspondingly, the network device receives the first information from the terminal device.
In this way, the network device may decide on the occasion to acquire the first information. For example, the network device may acquire the first information from the terminal device when network optimization is required, so that the flexibility of the network device in acquiring the first information is higher.
It should be noted that, for the terminal device, before receiving the first request from the network device, the terminal device may buffer the time when the first event occurs each time, the location where the terminal device is located, and update the number of times that the first event occurs at the location; until the terminal device receives the first request and sends the first information to the network device in response to the first request. Alternatively, in the case where the information for indicating the first event included in the first information includes the first frequency and/or the first level, the terminal device may determine the first frequency and/or the first level corresponding to each location based on the number of occurrences of the first event corresponding to each location. The manner in which the first frequency and/or the first level are determined may be referred to in the description above and will not be described in detail herein.
Illustratively, before receiving the first request from the network device, the terminal device fails to register 2 times in cell 1 and fails to establish 3 times of service in cell 2. The first information may include information indicating cell 1, 2 times, information indicating cell 2, and 3 times.
It should be appreciated that the manner in which the terminal device determines the first frequency and/or the first level according to the number of times the first event occurs may refer to the description above, and will not be repeated here.
Wherein the first request is for requesting a measurement result of the terminal device, i.e. for requesting the first information. The first information is a response of the terminal device to the first request.
On the basis of the above embodiment, optionally, the first request may carry one or several of the above information 1, information 2 or information 3. In this way, the terminal device can determine the first information based on the first request.
It should be understood that the time when the network device sends the first request to the terminal device may be before S201 or after S202, which is not particularly limited by the present application.
In an example, the moment when the network device sends the first request to the terminal device is before S201. And the first request carries information 1 and/or information 2. In this way, after each occurrence of the first event, the terminal device can determine the data to be acquired according to the information carried in the first request. For example, the first request carries information 1, where the information 1 is used to indicate the cell identifier and the TAC. When the first event occurs in the cell a, the terminal device determines the current time 1, caches the cell identifier 1 and the TAC 1 of the cell a, and records the number of times of the first event occurring in the cell a as 1 time. And the first information reported by the terminal device may include time 1, cell identifier 1, TAC 1 and 1 time.
In another example, the moment when the network device sends the first request to the terminal device is after S202. In this way, the terminal device can collect various data after each occurrence of the first event. After the first request is received, the data needing to be reported can be determined according to the information carried in the first request. For example, when a first event occurs in the cell a, the terminal device determines the current time 2, caches the cell identifier 2, the TAC 2, the PLMN ID 1 and the first coordinate of the cell a, and records the number of times of the occurrence of the first event in the cell a as 1 time; the first request carries information 1, where the information 1 is used to indicate a cell identifier and a TAC, and the first information reported by the terminal device may include time 2, the cell identifier 2, the TAC 2 and 1 time.
On the basis of the above embodiment, the first request may be, for example, a record measurement configuration (logged measurement configuration) message. In this way, the terminal device can perform measurement based on the recording measurement configuration and report information indicated by the recording measurement configuration. The network device can determine the time when the first event occurs, the location at which the terminal device is located, and how frequently the first event occurs at each location based on existing MDT mechanisms. Or the terminal equipment caches the information of the corresponding position when the three registration fails or the service establishment fails, namely, the position 1 corresponding to 8:00; position 2 corresponding to 12:00; and 18:00 corresponds to position 3. If the first time period is 10:00-14:00, reporting the position 2 by the terminal equipment, namely, the third information is used for indicating the position 2.
The present application also provides a communication method 300, the method 300 being applicable to the communication system 100. As shown in fig. 3, the method 300 includes the steps of:
s301, the network device sends information for indicating measurement configuration to the terminal device. Correspondingly, the terminal device receives information from the network device for indicating the measurement configuration. Wherein the information for indicating the measurement configuration may include, but is not limited to, one or more of the following: information 1, information 2 or information 3.
It should be understood that the description of the information 1, the information 2 and the information 3 can be referred to above, and will not be repeated here.
Alternatively, the information indicating the measurement configuration may be a record measurement configuration message.
In response to the information for indicating the measurement configuration, the terminal device may cache information such as a location where the terminal device is located and the number of times the first event occurs at the location in a case where it is determined that the first event occurs.
In some possible embodiments, S301 is optional content, that is, the terminal device caches the location where the terminal device is located whenever it determines that registration failure or service establishment failure occurs.
It should be noted that the information for indicating the measurement configuration may further include various information such as a form in which the terminal device caches the first information, which is not particularly limited in the present application.
S201, the terminal equipment sends second information to the network equipment, wherein the second information is used for requesting registration or for requesting establishment of service. Correspondingly, the network device receives the second information from the terminal device.
S202, the terminal equipment determines first information.
It should be understood that the embodiments of S201 and S202 may refer to the description in the method 200, and are not described herein.
S302, the network equipment sends a first request to the terminal equipment; correspondingly, the terminal device receives a first request from the network device.
It should be appreciated that the embodiment of S302 is similar to the embodiment of the method 200, and reference may be made to the above description, which is not repeated here.
In some possible embodiments, the first request is optional content, i.e. the terminal device determines and reports the first information based on the logged measurement configuration message.
It should be noted that S202 may precede S302 or follow S302. I.e. the terminal device may determine the first information each time it is determined that the first event has occurred and report the first information based on the first request. Therefore, the efficiency of reporting the first information by the terminal equipment is higher. Or after each occurrence of the first event, the terminal device may first buffer the location where the terminal device is located when the first event occurs and the frequency of occurrence of the first event at each location, and determine the first information based on the first request after receiving the first request. In this way, the terminal device may generate the first information in the corresponding form or including the corresponding information based on the first request. The present application is not particularly limited thereto.
S203, the terminal equipment sends the first information to the network equipment. Correspondingly, the network device receives the first information from the terminal device.
It should be understood that the embodiment of S203 may refer to the description in the method 200, and will not be described herein.
It should be noted that S201 is a step that may be performed repeatedly, that is, the terminal device may initiate registration or establish a service multiple times. And after executing S201 each time, if the terminal device determines that the first event occurs, the terminal device caches the location where the terminal device is located when the first event occurs, updates the number of times the first event occurs at the location, and the time when the first event occurs.
