Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to communication methods, devices and systems. Background Art

[0002] The RAN-based Notification Area (RNA) is composed of one or more cells. A terminal device in the Radio Resource Control (RRC) inactive (RRC_INACTIVE) state can be configured with RNA by the previous serving base station. The RAN side knows the RNA to which the terminal device belongs, so when the RAN side initiates paging for a terminal device in the RRC_INACTIVE state, the RAN will first page the terminal device in the cell within the RNA range to which the terminal device belongs.

[0003] The setting of RNA is a network planning issue, and the setting of RNA needs to be reasonable. If the RNA range is set too large, that is, one RNA contains more cells, the RAN side needs to page more cells when paging a terminal device, resulting in a large paging overhead of the network. If the RNA range is set too small, that is, one RNA contains fewer cells, the terminal device will trigger more RNA update (RNA Update, RNAU) processes due to frequent entry or exit of the RNA, resulting in a large overhead of the terminal device.

[0004] At present, the actual network situation is generally obtained through manual testing, and then RNA is planned according to the actual network situation and network deployment. However, once the RNA planning is completed, it will no longer change, but the actual situation is that sometimes the set RNA may not be appropriate (such as the range is too large or too small), resulting in a large overhead for the network or terminal equipment. Summary of the invention

[0005] The embodiments of the present application provide a communication method, device and system to achieve setting of a suitable RNA range.

[0024] In combination with the first aspect, in a possible implementation of the first aspect, when the terminal device receives fourth indication information from the network device for indicating to turn off the RNA information recording function, the recording of RNA information is paused or stopped; or, when the terminal device leaves the RRC inactive state, the recording of RNA information is paused or stopped.

[0025] In combination with the first aspect, in a possible implementation of the first aspect, the first information also includes mobility status information and / or mobile speed information of the terminal device; wherein the mobility status information includes the mobility status of the terminal device when generating the first information and / or the average mobility status of the terminal device within the first RNA; the mobile speed information includes the mobile speed of the terminal device when generating the first information and / or the average mobile speed of the terminal device within the first RNA.

[0026] In combination with the first aspect, in a possible implementation manner of the first aspect, the identification information of the first RNA includes an identification of the first RNA; or, the identification information of the first RNA includes an identification of the first RNA and an identification of a tracking area to which the first RNA belongs.

[0028] Based on the above scheme, the terminal device records the information of the RNA it has experienced, including information that can reflect the stay of the terminal device in the RNA (i.e., the second information). After receiving the RNA information reported by the terminal device, the network device can know which RNAs have abnormal terminal device stay time problems, and then determine whether the size setting of a certain RNA is reasonable, so that the network device sets a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and the network device.

[0029] In combination with the second aspect, in a possible implementation of the second aspect, the network device adjusts the first RNA according to the first information, including: the network device determines, based on the second information, that the length of time the terminal device stays in the first RNA is too long, and then reduces the range of the first RNA; or, the network device determines, based on the first information, that the length of time the terminal device stays in the first RNA is too short, and then increases the range of the first RNA.

[0031] Based on the above scheme, in addition to referring to the length of time the terminal device stays in the first RNA, the network device also refers to the mobile state information and / or mobile speed information of the terminal device, so as to more accurately determine whether the range of the first RNA is indeed too large or too small. For example, for a terminal device with a low mobility state or a slow moving speed, if the length of time the terminal device stays in the first RNA is too long, then the network device can determine according to method two that the range of the first RNA is not really too large, but that the length of time the terminal stays in the first RNA is too long due to the slow movement of the terminal itself, and therefore it is considered that there is no need to adjust the range of the first RNA, thereby achieving a better setting of the RNA range.

[0034] In combination with the second aspect, in a possible implementation of the second aspect, the at least one set of duration thresholds is configured to the terminal device through any one of the following messages: system information, radio resource control RRC release message, RRC connection release message.

[0038] In combination with the second aspect, in a possible implementation manner of the second aspect, the network device sends fourth indication information for instructing to close the RNA information recording function to the terminal device.

[0062] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0063] like Figure 1 FIG. 1 is a schematic diagram of a network architecture applicable to an embodiment of the present application, including a terminal device and a network device. The terminal device communicates with the network device via a wireless interface.

[0064] Terminal device is a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal device can be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, user equipment (UE), etc.

[0065] A network device is a device that provides wireless communication functions for a terminal device. The network device includes, but is not limited to: RAN equipment (next generation nodeB (gNB), evolved nodeB (eNB), etc.), radio network controller (RNC), nodeB (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved nodeB, or home nodeB, HNB), baseband unit (BBU), transmission point (TRP), transmitting point (TP), mobile switching center, etc. For ease of explanation, the network device is taken as a RAN device as an example in the embodiment of the present application.

[0066] To facilitate understanding of the embodiments of the present application, some terms are first introduced below.

[0067] 1. RNA

[0068] RNA consists of one or more cells. A terminal device in the Radio Resource Control (RRC) inactive state (RRC_INACTIVE) can be configured with RNA by the previous serving base station. The RAN side knows the RNA to which the terminal device belongs, so when the RAN side initiates paging for a terminal device in the RRC_INACTIVE state, the RAN will first page the terminal device within the RNA to which the terminal device belongs.

[0069] 2. RAN-based Notification Area Update (RNAU)

[0070] The RNAU process is a process triggered by the terminal device to synchronize RNA information to the RAN. The basic process of this process is that the terminal device sends an RRC resume message (RRCResumeRequest message) or an RRC connection resume message (RRCConnectionResumeRequest message) to the RAN device, and the resume cause value field (resumeCause) in the message is set to 'rna-Update'. After receiving the message, the RAN device will know that the terminal device has currently triggered the RNA update process, and then the RAN device will perform the relevant operations of the RNAU process.

[0071] When the terminal device moves within the RNA range, the RAN may not be notified. However, when the terminal device leaves the current RNA range, the RNAU process may be triggered to notify the RAN device that the current RNA of the terminal device has changed.

[0072] In addition, in order to maintain RNA, the terminal device can also periodically initiate the RNAU process. Specifically, when the terminal device enters the RRC_INACTIVE state, the terminal device starts a timer T380. When T380 times out, regardless of whether the current RNA of the terminal device has changed, the terminal device needs to initiate the RNAU process and synchronize the RNA information with the RAN device.

[0073] 3. Mobility History Information (MHI)

[0074] MHI is a record of the historical movement of the terminal device. The specific content of MHI is a list of cells that the terminal device has visited. For example, the terminal device records the identifiers of the 16 service cells that it has visited most recently in chronological order. Among them, the service cell can be a new radio (NR) cell or an evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) cell, and the cell identifier can be a physical cell identifier (PCI) or a cell global identifier (CGI).

[0075] In order to solve the problems mentioned in the background technology, based on Figure 1 The network architecture shown in Figure 2As shown, an embodiment of the present application provides a communication method. On the terminal device side, the method can be executed by the terminal device or a component (such as a chip, circuit, etc.) used for the terminal device; on the network side, it can be executed by the network device or a component (such as a chip, circuit, etc.) used for the network device. For ease of description, the following is an example of a terminal device and a network device executing the method.

[0076] The method comprises the following steps:

[0077] Step 201: A terminal device generates first information, where the first information includes identification information of a first RNA and second information, where the second information is used to determine time information of the terminal device within the first RNA.

[0078] The first information may also be referred to as RNA information, which is used to record the identification information of the first RAN where the UE is located and the time information of the UE in the first RNA. The second information is used to record the time information of the UE in the first RNA. For example, the time information includes: the length of stay is too long, the length of stay is too short, and the length of stay is normal. For another example, the time information includes: the length of stay is too long, the length of stay is long, the length of stay is normal, the length of stay is short, the length of stay is too short, and so on.

[0079] The terminal device may be a terminal device in an RRC inactive state.

[0080] The first RNA may be an RNA where the terminal device is located, and the RNA includes one or more cells.

[0081] As an implementation method, the identification information of the first RNA includes the identification of the first RNA, that is, an RNA is uniquely identified by the identification of the RNA.

[0082] As another implementation method, the identification information of the first RNA includes the identification of the first RNA and the identification of the Tracking Area (TA) to which the first RNA belongs (ie, Tracking Area Identity (TAI)). That is, an RNA is uniquely identified by an RNA identification and a TAI.

[0083] Step 202: The terminal device sends second indication information to the network device, where the second indication information is used to indicate that the terminal device has recorded the first information. Accordingly, the network device can receive the second indication information.

[0084] Step 203: The network device sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to send the first information. Accordingly, the terminal device can receive the third indication information.

[0085] The above steps 202 and 203 are optional steps.

[0086] Step 204: The terminal device sends the first information to the network device. Correspondingly, the network device can receive the first information.

[0087] Step 205: The network device adjusts the first RNA according to the first information.

[0088] The embodiment of the present application does not limit the specific implementation method of the network device adjusting the first RNA according to the first information.

[0089] As an example, the method for the network device to adjust the first RNA according to the first information may include:

[0090] Method 1: The network device adjusts the first RNA according to the second information in the first information.

[0091] For example, when the time information includes: the length of stay is too long, the length of stay is normal, and the length of stay is too short. If the network device determines that the length of stay of the terminal device in the first RNA is too long according to the second information, the range of the first RNA is reduced, such as reducing the number of cells in the first RNA so that the range of the first RNA is reduced. If the network device determines that the length of stay of the terminal device in the first RNA is too short according to the second information, the range of the first RNA is increased, such as increasing the number of cells in the first RNA so that the range of the first RNA is increased.

[0092] For another example, when the time information includes: the dwell time is too long, the dwell time is long, the dwell time is normal, the dwell time is short, and the dwell time is too short. If the network device determines that the dwell time of the terminal device in the first RNA is too long or the dwell time is long according to the second information, the range of the first RNA is reduced, such as reducing the number of cells in the first RNA so that the range of the first RNA is reduced, wherein the reduction in the range of the first RNA when the dwell time is too long is greater than the reduction in the range of the first RNA when the dwell time is long. If the network device determines that the dwell time of the terminal device in the first RNA is too short or the dwell time is short according to the second information, the range of the first RNA is increased, such as increasing the number of cells in the first RNA so that the range of the first RNA is increased, wherein the increase in the range of the first RNA when the dwell time is too short is greater than the increase in the range of the first RNA when the dwell time is short.

[0093] Of course, when the time information is divided according to other classification methods, the range of the first RAN is adjusted in a corresponding manner, which will not be described in detail.

[0094] Method 2: The above-mentioned first information also includes mobility status information and / or mobile speed information of the terminal device. The network device adjusts the first RNA according to the second information in the first information and the mobility status information and / or mobile speed information of the terminal device.

[0095] That is, the network device adjusts the first RNA according to the second information and the mobility state information of the terminal device. Alternatively, the network device adjusts the first RNA according to the second information and the moving speed information of the terminal device. Alternatively, the network device adjusts the first RNA according to the second information, the mobility state information of the terminal device, and the moving speed information of the terminal device.

[0096] Among them, the mobility state of the terminal device is used to indicate the frequency of the terminal device changing the service cell. For example, when the number of times the terminal device changes the service cell within a set time period is greater than or equal to the preset first number threshold, the mobility state of the terminal device is high mobility. When the number of times the terminal device changes the service cell within a set time period is less than the preset first number threshold and greater than the preset second number threshold, the mobility state of the terminal device is medium mobility. When the number of times the terminal device changes the service cell within a set time period is less than or equal to the preset second number threshold, the mobility state of the terminal device is normal mobility.

[0097] In the embodiment of the present application, the mobility state information in the first information may include the mobility state when the terminal device generates the first information and / or the average mobility state of the terminal device within the first RNA.

[0098] The moving speed information of the terminal device is used to indicate the moving speed (speed) of the terminal device.

[0099] In the embodiment of the present application, the moving speed information in the first information includes the moving speed of the terminal device when generating the first information and / or the average moving speed of the terminal device within the first RNA.

[0100] For the second method, taking the time information including: the dwell time is too long, the dwell time is normal, and the dwell time is too short as an example, the method for the network device to adjust the first RNA includes: if the network device determines that the dwell time of the terminal device in the first RNA is too long according to the second information, and determines that the terminal device is highly mobile according to the mobility state information and / or determines that the moving speed of the terminal device is greater than or equal to the first speed threshold according to the moving speed information, then reduce the range of the first RNA, such as reducing the number of cells in the first RNA so that the range of the first RNA is reduced. Alternatively, if the network device determines that the dwell time of the terminal device in the first RNA is too short according to the first information, and determines that the terminal device is low mobile according to the mobility state information and / or determines that the moving speed of the terminal device is less than or equal to the second speed threshold according to the moving speed information, then increase the range of the first RNA, such as increasing the number of cells in the first RNA so that the range of the first RNA is increased.

[0101] For the above-mentioned method 2, in addition to referring to the length of time the terminal device stays in the first RNA, the network device also refers to the mobile state information and / or mobile speed information of the terminal device, so as to more accurately determine whether the range of the first RNA is indeed too large or too small. For example, for a terminal device with a low mobility state or a slow moving speed, if the length of time the terminal device stays in the first RNA is too long, then the network device can determine according to method 2 that the range of the first RNA is not really too large, but that the length of time the terminal stays in the first RNA is too long due to the slow movement of the terminal itself, and therefore it is considered that there is no need to adjust the range of the first RNA, thereby achieving a better setting of the RNA range.

[0102] based on Figure 2 In a corresponding embodiment, a terminal device in an RRC inactive state records information about the RNA it has experienced, including information that can reflect the terminal device's stay in the RNA. After receiving the RNA information reported by the terminal device, the network device can learn which RNAs have abnormal terminal device stay times, and then determine whether the size setting of a certain RNA is reasonable. For example, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too large, and the RNA range can be reduced. On the contrary, if the terminal device stays in a certain RNA for too short a time, it means that the RNA range may be too small, and the RNA range can be increased. This achieves the setting of a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and the network device.

[0103] Various different implementation methods of the first information and the second information in the above embodiment are given below.

[0104] Implementation method 1: The second information includes first indication information, and the first indication information is used to indicate the time information of the terminal device in the first RNA.

[0105] For example, the time information includes: the length of stay is too long, the length of stay is too short, and the length of stay is normal. For another example, the time information includes: the length of stay is too long, the length of stay is long, the length of stay is normal, the length of stay is short, the length of stay is too short, and so on.

[0106] Implementation method 2, the second information includes the length of time the terminal device stays in the first RNA.

[0107] Implementation method three, the second information includes a timestamp when the terminal device enters the first RNA and a timestamp when the terminal device leaves the first RNA.

[0108] For any of the implementation methods 1 to 3 above, optionally, before the above step 201, the terminal device may receive at least one set of duration thresholds from the network device, each set of duration thresholds including at least one duration threshold. Optionally, if two or more sets of duration thresholds are received, the terminal device selects a suitable set of thresholds according to its own mobility (such as mobility state information and / or mobile speed information). For example, when the selected set of duration thresholds includes two duration thresholds (such as a first duration threshold and a second duration threshold, wherein the first duration threshold is greater than or equal to the second duration threshold), the two duration thresholds can be divided into three stay duration intervals, and thus the time information can be divided into: too short stay duration (when the stay duration is less than or equal to the second duration threshold), normal stay duration (when the stay duration is less than the first duration threshold and greater than the second duration threshold), and too long stay duration (when the stay duration is greater than or equal to the first duration threshold). For another example, when the selected set of duration thresholds includes four duration thresholds, the four duration thresholds can be divided into five stay duration intervals, and thus the time information can be divided into: too short stay duration, short stay duration, normal stay duration, long stay duration, and too long stay duration. This analogy is used and will not be repeated.

[0109] Taking the case where a set of selected duration thresholds includes two duration thresholds (respectively, a first duration threshold and a second duration threshold), the first duration threshold is greater than or equal to the second duration threshold, the first duration threshold is used to determine whether the duration of stay of the terminal device in the first RNA is too long, and the second duration threshold is used to determine whether the duration of stay of the terminal device in the first RNA is too short. When the terminal device leaves the first RNA, if it is determined that the duration of stay in the first RNA is greater than or equal to the first duration threshold, it is determined that the duration of stay of the terminal device in the first RNA is too long, and the terminal device is triggered to generate the above-mentioned first information. Alternatively, when the terminal device leaves the first RNA, if it is determined that the duration of stay in the first RNA is less than or equal to the second duration threshold, it is determined that the duration of stay of the terminal device in the first RNA is too short, and the terminal device is also triggered to generate the above-mentioned first information.

[0110] Optionally, the above-mentioned at least one set of duration thresholds can be configured to the terminal device in any of the following ways: system information (SI), RRC release message, and RRC connection release message.

[0111] Implementation method 4, the second information includes a timestamp when the terminal device triggers the RNA update process.

[0112] That is, the implementation method is that each time the terminal device triggers the RNA update (i.e., RNAU) process, the RNA information (such as the first information mentioned above) is recorded once. The RNAU process can be triggered when the terminal device leaves the first RNA, or when the RNAU cycle arrives. Thus, the network device can determine the length of time the terminal device stays in the first RNA from the multiple RNA information received.

[0113] Optionally, the terminal device records the RNA information only once when the terminal device leaves a certain RNA (such as the first RNA). The terminal device leaving the RNA means that the terminal device triggers the RNAU process and the RNA changes.

[0114] Implementation method five, the second information includes a timestamp when the terminal device records the MHI.

[0115] That is, the implementation method is that each time the terminal device records the MHI, the RNA information (ie, the first information) is recorded in the MHI. The terminal device may record the MHI each time it leaves the cell.

[0116] Optionally, if the terminal device does not leave the first RNA when recording the MHI, the terminal device does not record the RNA information in the MHI. Alternatively, it can be understood that when the terminal device needs to record the MHI, if the terminal device just leaves a certain RNA (such as the first RNA), the terminal device can record an RNA information (such as the above-mentioned first information) in the MHI when recording the MHI.

[0117] Optionally, in combination with any one of the implementation methods one to five above, the mobility status information and / or moving speed information of the terminal device may also be carried in the first information above, as described above and will not be repeated here.

[0118] As an implementation method, in combination with any of the above embodiments, the network device may also send configuration parameters to the terminal device before the above step 201, and the configuration parameters include one or more of the following: recording time length, recording time range, maximum number of recording items, maximum storage capacity of recording items, and effective area of ​​recording. The configuration method may be:

[0119] The system information is broadcasted, or sent to the terminal device through an RRC release message, or sent to the terminal device through an RRC connection release message. Therefore, when the terminal device determines that one or more of the following conditions are met at any time, the terminal device pauses or stops recording RNA information:

[0120] Condition 1: The terminal device reaches the recording time length;

[0121] Condition 2: The terminal device leaves the recording time range;

[0122] Condition 3: The terminal device reaches the maximum number of record items;

[0123] Condition 4: The terminal device reaches the maximum storage capacity of the record item;

[0124] Condition 5: The terminal device leaves the valid area of ​​the record.

[0125] The valid area may consist of cells or RNA or tracking areas, or it may be an actual geographical area (eg, an area defined by coordinates or longitude and latitude).

[0126] As another implementation method, when the terminal device receives instruction information (which may be referred to as fourth instruction information) for instructing to turn off the RNA information recording function from the network device, the terminal device pauses or stops recording the RNA information.

[0127] As another implementation method, when the terminal device leaves the RRC inactive state, the terminal device pauses or stops recording RNA information. The terminal device leaving the RRC inactive state includes: the terminal device entering the RRC idle state (RRC_IDLE), or the RRC connected (RRC_CONNECTED) state, or the terminal device reselects to an inter-Radio Access Technology (Radio Access Technology, RAT) cell, or the terminal device enters the "camped on any cell" state (i.e. out-of-coverage).

[0128] That is, after the terminal device determines to pause or stop recording RNA information, RNA information similar to the above-mentioned first information will no longer be generated.

[0129] As an implementation method, in combination with any of the above embodiments, before step 201, the terminal device may also receive indication information (which may be called the fifth indication information) from the network device for indicating to start the RNA information recording function, so that the terminal device executes the above step 201, that is, starts recording RNA information.

[0130] As an implementation method, when the implementation method of the above-mentioned second information is any one of implementation methods one to four, and the above-mentioned steps 202 and 203 are performed, the second indication information of the above-mentioned step 202 can be carried in an RRC recovery request (RRCResumeRequest) message, or an RRC establishment request (RRCSetupRequest) message, or an RRC connection recovery request (RRCConnectionResumeRequeste) message, or an RRC connection request (RRCConnectionRequest) message, or an RRC recovery completion (RRCResumeComplete) message, or an RRC establishment completion (RRCSetupComplete) message, or an RRC connection recovery completion (RRCConnectionResumeComplete) message, or an RRC connection establishment completion (RRCConnectionSetupComplete) message, or an RRC reconfiguration completion (RRCReconfigurationComplete) message, and the third indication information of the above-mentioned step 203 can be carried in a UE information request (UE information The first information of the above step 204 may be carried in a UE information response (UEinformation Response) message, or an RRC recovery request message, or an RRC establishment request message, or an RRC connection recovery request message, or an RRC connection request message, or an RRC recovery complete message, or an RRC establishment complete message, or an RRC connection recovery complete message, or an RRC connection establishment complete message, or an RRC reconfiguration complete message. It should be noted that, in a reporting process, the messages of the above-mentioned step 202 and step 204 are different messages. For example, when the second indication information of step 202 is carried in the RRC recovery request message, the first information of step 204 is not carried in the RRC recovery request message, for example, it can be carried in a UE information response message, or an RRC recovery completion message, or an RRC establishment completion message, or an RRC reconfiguration completion message.

[0131] As an implementation method, when the implementation method of the above-mentioned second information is any one of implementation methods one to four, and the above-mentioned steps 202 and 203 are not performed, the first information of the above-mentioned step 204 can be carried in a UE information response message, or an RRC recovery request message, or an RRC establishment request message, or an RRC connection recovery request message, or an RRC connection request message, or an RRC recovery completion message, or an RRC establishment completion message, or an RRC connection recovery completion message, or an RRC connection establishment completion message, or an RRC reconfiguration completion message.

[0132] As an implementation method, when the implementation method of the second information is implementation method five, that is, reporting the first information through MHI, the MHI carrying the first information in the embodiment of the present application can be reported in accordance with the method of reporting MHI in the prior art. Specifically, the second indication information of the above step 202 can be carried in an RRC recovery completion message, or an RRC establishment completion message, or an RRC connection recovery completion message, or an RRC connection establishment completion message, the third indication information of the above step 203 can be carried in a UE information request message, and the first information of the above step 204 can be carried in a UE information response message.

[0133] It should be noted that, in the embodiment of the present application, the terminal device may record one or more RNA information before the sending time point of the RNA information is reached. Of course, if the trigger condition for pausing or stopping the recording of the RNA information is met, the terminal device pauses or stops recording the RNA information. When the sending time point of the RNA information is reached, the terminal device sends the recorded one or more RNA information to the network device. Among them, the sending time point of the RNA information may be the sending time of the message carrying the RNA information. For example, if the recorded RNA information is carried in the RRC recovery message, the time point of sending the RRC recovery message is the sending time point of the RNA information.

[0134] Therefore, in the embodiment of the present application, in the above step 204, the terminal device can send multiple RNA information to the network device, including the above first information.

[0135] Combine the following Figures 3 to 5 The specific example shown above Figure 2 The process shown is introduced and explained.

[0136] like Figure 3 As shown, it is a flow chart of another communication method provided in an embodiment of the present application. Figure 2The implementation methods 1 to 3 of the second information in the corresponding embodiments. This embodiment introduces a duration threshold, and the terminal device determines the time information in the RNA according to the duration threshold, and records the RNA information of the UE when the stay duration is abnormal (i.e. too long, too short, longer, shorter, etc.).

[0137] The method comprises the following steps:

[0138] Step 301: The network device configures at least one set of duration thresholds for the terminal device.

[0139] Each group of duration thresholds includes at least one duration threshold.

[0140] As an implementation method, the setting of the duration threshold may take into account the mobility factor of the terminal device. For example, different duration thresholds are set for different mobility states. For example, assuming that there are three mobility states, namely, high, normal, and low, three groups of corresponding duration thresholds are configured for these three mobility states, and each group of duration thresholds includes at least one duration threshold. For another example, different duration thresholds are set for different moving speeds. For example, assuming that the moving speed has different values, a corresponding number of groups of duration thresholds are configured for different moving speeds, and each group of duration thresholds includes at least one duration threshold.

[0141] If the UE receives two or more groups of duration thresholds, the terminal device selects an appropriate group of thresholds according to its own mobility (such as mobility state information and / or moving speed information).

[0142] The configuration method may be: broadcasting through system information, sending through an RRC release message to the terminal device, or sending through an RRC connection release message to the terminal device.

[0143] Step 302: The terminal device generates an RNA message.

[0144] Specifically, when the terminal device leaves a certain RNA (such as the first RNA), the terminal device determines that the duration of stay of the terminal device in the first RNA is abnormal according to a set of duration thresholds selected from at least one set of received duration thresholds, and the terminal device generates the above-mentioned RNA information. Among them, the terminal device determines whether the duration of stay is abnormal by judging the size relationship between the duration T of stay in the first RNA and a set of selected duration thresholds. Taking the selected set of duration thresholds as an example including two duration thresholds (the first duration threshold TH1 and the second duration threshold TH2, respectively, where TH1 is greater than or equal to TH2), if the duration T is greater than or equal to TH1, or T is less than or equal to TH2, the terminal device determines that the duration of stay is abnormal (including the duration of stay is too long, or the duration of stay is too short), and the terminal device generates an RNA information. Among them, the terminal device leaving a certain RNA can also be called triggering the RNAU process and the RNA changes.

[0145] The RNA information generated by the terminal device includes RNA information of the first RNA, specifically including one or more of the following 1) to 5):

[0146] 1) Identification of the first RNA;

[0147] 2) the identifier of the tracking region to which the first RNA belongs (i.e., TAI);

[0148] 3) Information about the time the terminal device stays in the first RNA, such as any one or more of the following:

[0149] a) An indication information (which may be referred to as the first indication information) is used to indicate the time information of the terminal device in the first RNA.

[0150] Taking the case where a selected set of duration thresholds includes two duration thresholds (respectively, a first duration threshold TH1 and a second duration threshold TH2, where TH1 is greater than or equal to TH2), when the stay duration T is greater than or equal to TH1, the first indication information is used to indicate that the stay duration T is too long, and when the stay duration T is less than or equal to TH2, the first indication information is used to indicate that the stay duration T is too short. For example, the first indication information is 1', indicating that T is greater than or equal to TH1, and the first indication information is '0', indicating that T is less than or equal to TH2; or the first indication information is 0', indicating that T is greater than or equal to TH1, and the first indication information is '1', indicating that T is less than or equal to TH2.

[0151] b) the length of time T that the terminal device stays in the first RNA;

[0152] c) timestamps of the terminal device entering and leaving the first RNA;

[0153] 4) The mobility state and / or moving speed of the terminal device;

[0154] The mobility state may be the mobility state of the terminal device when recording RNA information, or the average mobility state of the terminal device in the first RNA. The moving speed may be the moving speed of the terminal device when recording RNA information, or the average moving speed of the terminal device in the first RNA.

[0155] 5) the cell identifier when the terminal device enters and / or leaves the first RNA;

[0156] The cell identifier may be a PCI or a CGI.

[0157] If the reported RNA information includes the cell identifier when the terminal device enters and / or leaves the first RNA, the network device can better adjust the size of the RNA according to the cell identifier when the terminal device enters and / or leaves the first RNA. For example, when the cell when the terminal device enters the first RNA and the cell when it leaves the first RNA are far apart, the network device believes that the length of time the terminal device stays in the first RNA has a reference value, and thus the size of the first RNA can be adjusted according to the length of time. When the cell when the terminal device enters the first RNA and the cell when it leaves the first RNA are close to each other, the network device believes that the length of time the terminal device stays in the first RNA does not have a reference value, and thus the size of the first RNA may not be adjusted temporarily.

[0158] Step 303: The terminal device stops or pauses recording RNA information.

[0159] This step is optional. When one or more of the following conditions are met, the terminal device stops or pauses recording RNA information:

[0160] Condition 1: The terminal device reaches the recording time length;

[0161] Condition 2: The terminal device leaves the recording time range;

[0162] Condition 3: The terminal device reaches the maximum number of record items;

[0163] Condition 4: The terminal device reaches the maximum storage capacity of the record item;

[0164] Condition 5: The terminal device leaves the valid area of ​​the record.

[0165] The recording time length, the recording time range, the maximum number of recording items, the maximum storage capacity of the recording items, and the valid area may be collectively referred to as configuration parameters, which may be sent from the network device to the terminal device before the above step 302. The configuration may be: broadcasted through system information, sent to the terminal device through an RRC release message, or sent to the terminal device through an RRC connection release message.

[0166] As another implementation method, when the terminal device receives instruction information (which may be referred to as fourth instruction information) for instructing to turn off the RNA information recording function from the network device, the terminal device pauses or stops recording the RNA information.

[0167] As another implementation method, when the terminal device leaves the RRC inactive state, the terminal device pauses or stops recording RNA information.

[0168] Optionally, before step 302, the terminal device may also receive instruction information (which may be referred to as fifth instruction information) from the network device for instructing to enable the RNA information recording function.

[0169] Step 304: The terminal device sends second indication information to the network device, for notifying the network that RNA information is recorded at the terminal device.

[0170] Step 305: The network device sends third instruction information to the terminal device, which is used to instruct the terminal device to send the recorded RNA information.

[0171] The above steps 304 to 304 are optional steps.

[0172] Step 306: The terminal device sends the generated RNA information to the network device.

[0173] Step 307: The network device adjusts the first RNA according to the RNA information.

[0174] The specific implementation method of this step can be found in Figure 2 The relevant description of step 204 of the corresponding embodiment is not repeated here.

[0175] Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the stay of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device can know which RNAs have abnormal terminal device stay time problems, and then judge whether the size setting of a certain RNA is reasonable. For example, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too large, and the RNA range can be reduced. On the contrary, if the terminal device stays in a certain RNA for too short a time, it means that the RNA range may be too small, and the RNA range can be increased. Thereby, a suitable RNA range is set for the terminal device, which helps to reduce the overhead of the terminal device and the network device.

[0176] like Figure 4 As shown, it is a flow chart of another communication method provided in an embodiment of the present application. Figure 2 The corresponding method 4 for implementing the second information in the embodiment: In this embodiment, the terminal device records RNA information once each time the RNAU process is triggered.

[0177] The method comprises the following steps:

[0178] Step 401: Each time the terminal device triggers the RNAU process, it generates an RNA message, where the RNA message includes RNA information of the first RNA, specifically including one or more of the following 1) to 5):

[0179] 1) Identification of the first RNA.

[0180] 2) The identifier of the tracking area to which the first RNA belongs (ie, TAI).

[0181] 3) The timestamp of the terminal device triggering the RNAU process, or the length of time the terminal device stays in the first RNA when triggering the RNAU process.

[0182] 4) The mobility state and / or moving speed of the terminal device.

[0183] The mobility state may be the mobility state of the terminal device when recording RNA information, or the average mobility state of the terminal device in the first RNA. The moving speed may be the moving speed of the terminal device when recording RNA information, or the average moving speed of the terminal device in the first RNA.

[0184] 5) The cell identifier when the terminal device enters and / or leaves the first RNA.

[0185] The cell identifier may be a PCI or a CGI.

[0186] If the reported RNA information includes the cell identifier when the terminal device enters and / or leaves the first RNA, the network device can better adjust the size of the RNA according to the cell identifier when the terminal device enters and / or leaves the first RNA. For example, when the cell when the terminal device enters the first RNA and the cell when it leaves the first RNA are far apart, the network device believes that the length of time the terminal device stays in the first RNA has a reference value, and thus the size of the first RNA can be adjusted according to the length of time. When the cell when the terminal device enters the first RNA and the cell when it leaves the first RNA are close to each other, the network device believes that the length of time the terminal device stays in the first RNA does not have a reference value, and thus the size of the first RNA may not be adjusted temporarily.

[0187] Since the network device only needs to know the time information when the terminal device enters and leaves the first RNA, it can calculate the length of time the terminal device stays in the first RNA, or the terminal device directly reports the length of time it stays in the first RNA when leaving the first RNA. Therefore, optionally, the above-mentioned triggering RNAU process can be triggered by the terminal device leaving the RNA. Or it can be understood that when the RNAU process is triggered, if the current RNA of the terminal device has not changed, the terminal device does not generate RNA information when triggering this RNAU process.

[0188] Among them, the terminal device leaving a certain RNA can also be called triggering the RNAU process and the RNA changes.

[0189] Step 402 to step 406, same Figure 3 For steps 303 to 307 of the corresponding embodiment, reference may be made to the above description and will not be repeated here.

[0190] Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the stay of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device can calculate the stay time of the terminal device in the RNA according to the reported timestamp of the triggering RNAU process, or the terminal device directly reports the stay time in the RNA, and then the network device determines whether the terminal device has an abnormal stay time problem, and then determines whether the size setting of the RNA is reasonable. For example, if the stay time of the terminal device in a certain RNA is too long, it means that the RNA range may be too large, and then the RNA range can be reduced. On the contrary, if the stay time of the terminal device in a certain RNA is too short, it means that the RNA range may be too small, and then the RNA range can be increased. Thereby, a suitable RNA range is set for the terminal device, which helps to reduce the overhead of the terminal device and the network device.

[0191] It should be noted that Figure 4 The corresponding embodiments and Figure 3 The main differences between the corresponding embodiments are: Figure 3 In real time, the terminal device reports the abnormal RNA information, and the network device can directly know which RNA may have problems and then adjust the RNA size. Figure 4 In the corresponding embodiment, the terminal device reports the information of the RNA passed by the terminal device, and the network device needs to determine which RNA may be abnormal according to the stay of the RNA passed by the terminal device, and then adjust the RNA size.

[0192] like Figure 5 As shown, it is a flow chart of another communication method provided in an embodiment of the present application. Figure 2 The fifth implementation method of the second information in the corresponding embodiment: This embodiment considers enhancing the existing MHI, and the terminal device adds RNA information to the MHI while recording the MHI.

[0193] The method comprises the following steps:

[0194] Step 501: Each time the terminal device records the MHI, the terminal device adds RNA information to the MHI. The RNA information includes RNA information of the first RNA, specifically including one or more of the following 1) to 4):

[0195] 1) Identification of the first RNA.

[0196] 2) The identifier of the tracking area to which the first RNA belongs (ie, TAI).

[0197] 3) The timestamp of the terminal device recording the RNA information, or the current length of time the terminal device stays in the first RNA.

[0198] The timestamp when the terminal device records the RNA information may also be understood as the timestamp when the terminal device records the MHI.

[0199] 4) The mobility state and / or moving speed of the terminal device;

[0200] The mobility state may be the mobility state of the terminal device when recording RNA information, or the average mobility state of the terminal device in the first RNA. The moving speed may be the moving speed of the terminal device when recording RNA information, or the average moving speed of the terminal device in the first RNA.

[0201] Since the network device only needs to know the time information when the terminal device enters and leaves the first RNA, it can calculate the length of time the terminal device stays in the first RNA, or the terminal device directly reports the length of time it stays in the first RNA when leaving the first RNA. Therefore, optionally, when the terminal device records MHI, if the current RNA of the terminal device does not change, the terminal device does not record the RNA information in the MHI. Or it can be understood that only when the terminal device leaves the RNA (such as the first RNA mentioned above), the terminal device records the RNA information in the MHI while recording the MHI.

[0202] Step 502: The terminal device stops or pauses recording RNA information.

[0203] This step is the same as Figure 3 For step 303 of the corresponding embodiment, reference may be made to the above description and will not be repeated here.

[0204] This step is optional.

[0205] Step 503: The terminal device sends the MHI including RNA information to the network device.

[0206] Step 504: The network device adjusts the first RNA according to the RNA information.

[0207] The specific implementation method of this step can be found in Figure 3 The relevant description of step 307 of the corresponding embodiment is not repeated here.

[0208] Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the stay of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device can calculate the stay time of the terminal device in the RNA according to the timestamp of the reported recorded RNA information, and then the network device determines whether the terminal device has an abnormal stay time problem, and then determines whether the size setting of the RNA is reasonable. For example, if the stay time of the terminal device in a certain RNA is too long, it means that the RNA range may be too large, and then the RNA range can be reduced. On the contrary, if the stay time of the terminal device in a certain RNA is too short, it means that the RNA range may be too small, and then the RNA range can be increased. Thereby, a suitable RNA range is set for the terminal device, which helps to reduce the overhead of the terminal device and the network device.

[0209] It should be noted that Figure 5 The corresponding embodiments and Figure 4 The main differences between the corresponding embodiments are: Figure 5 In the corresponding embodiment, the terminal device carries RNA information in the reported MHI, and Figure 4The corresponding embodiment is to record RNA information when the RNAU process is triggered, and then report the recorded one or more RNA information after the reporting time point arrives.

[0210] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the interaction between various network elements. It can be understood that in order to realize the above functions, the above-mentioned network elements include hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed in this document, the present invention can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present invention.

[0211] It can be understood that, in the above-mentioned method embodiments, the steps or operations implemented by the terminal device can also be implemented by components configured in the terminal device (such as chips or circuits), and the steps or operations implemented by the network device can also be implemented by components configured in the network device (such as chips or circuits).

[0212] The embodiments of the present application also provide a device for implementing any of the above methods, for example, a device is provided including a unit (or means) for implementing each step performed by the terminal device in any of the above methods. For another example, another device is provided, including a unit (or means) for implementing each step performed by the network device in any of the above methods.

[0213] refer to Figure 6 , is a schematic diagram of a communication device provided in an embodiment of the present application. The device is used to implement each step performed by the corresponding terminal device in the above method embodiment, such as Figure 6 As shown, the device 600 includes a processing unit 610 and a transceiver unit 620. The processing unit 610 is used to generate first information, wherein the first information includes identification information of a first RNA and second information, wherein the second information is used to determine time information of a terminal device in the first RNA. The transceiver unit 620 is used to send the first information to a network device.

[0214] In a possible implementation, the second information includes first indication information, and the first indication information is used to indicate the time information of the communication device in the first RNA; or, the second information includes the length of time the communication device stays in the first RNA; or, the second information includes a timestamp of the communication device entering the first RNA and a timestamp of leaving the first RNA.

[0216] In a possible implementation manner, the at least one set of duration thresholds is configured to the communication device in any of the following ways: system information, radio resource control RRC release message, and RRC connection release message.
