Description

Communication method, device and system

Technical field

The embodiments of the present application relate to the field of communication technologies, and in particular, to communication methods, devices, and systems.

Background technique

The RAN-based Notification Area (RNA) based on the Radio Access Network (RAN) is composed of one or more cells. A terminal device in a radio resource control (Radio Resource Control, RRC) inactive (RRC_INACTIVE) state can configure RNA from the previous serving base station. The RAN side knows the RNA to which the terminal device belongs. Therefore, when the RAN side initiates a paging to a terminal device in the RRC_INACTIVE state, the RAN will first page the terminal device in a cell within the range of the RNA to which the terminal device belongs.

The setting of RNA is a network planning problem, 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 in more cells when paging a certain terminal device, resulting in higher 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 departure of the RNA, resulting in higher terminal device overhead.

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, no changes will occur. However, the actual situation is that sometimes the set RNA may not be appropriate (for example, the range is too large or too small), which causes a large network or terminal equipment overhead.

Detailed ways

In order to make the purpose, technical solutions, 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. Wherein, in the description of the present application, unless otherwise specified, "multiple" means two or more.

As shown in FIG. 1, it is a schematic diagram of a network architecture to which the embodiments of this application are applicable, including terminal equipment and network equipment. The terminal device communicates with the network device through a wireless interface.

Terminal device (terminal device) is a device with wireless transceiver function. It can be deployed on land, including indoor or outdoor, 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 may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, an industrial control (industrial control) Wireless terminals in ), wireless terminals in self-driving, wireless terminals in remote medical, wireless terminals in smart grid, and wireless terminals in transportation safety , Wireless terminals in smart cities, wireless terminals in smart homes, user equipment (UE), etc.

Network equipment is a device that provides wireless communication functions for terminal equipment. Network equipment includes but is not limited to: RAN equipment (next generation nodeB (gNB), evolved node B (evolved node B, eNB), etc.) , Radio network controller (RNC), node B (node B, NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home Evolved nodeB, or home node B, HNB, baseband unit (BBU), transmitting and receiving point (TRP), transmitting point (TP), mobile switching center, etc. For ease of description, in the embodiment of the present application, the network device is an RAN device as an example for description.

In order to facilitate the understanding of the embodiments of the present application, some terms will be introduced below.

1. RNA

RNA is composed of one or more cells. A terminal device in a radio resource control (Radio Resource Control, RRC) inactive state (RRC_INACTIVE) can configure RNA by the previous serving base station. The RAN side knows the RNA to which the terminal device belongs. Therefore, when the RAN side initiates a paging to a terminal device in the RRC_INACTIVE state, the RAN will first page the terminal device within the range of the RNA to which the terminal device belongs.

2. RAN-based Notification Area Update (RNAU)

The RNAU process is the process of synchronizing RNA information to the RAN triggered by the terminal device. The basic flow of this process is that the terminal device sends an RRC resume message (RRCResumeRequest message) or an RCC connection resume message (RRCConnectionResumeRequest message) to the RAN device. The resume cause value field (resumeCause) in the message is set to'rna-Update', then the RAN device After receiving the message, it can be known that the terminal device currently triggers the RNA update process, and then the RAN device will perform the relevant operations of the RNAU process.

When the terminal device moves within the RNA range, the RAN may not be notified, and 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.

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 changes, the terminal device All devices need to initiate an RNAU process to synchronize RNA information with the RAN device.

3. Mobile History Information (Mobility History Information, MHI)

MHI is the record information about the historical movement of the terminal equipment, and the specific content of the MHI is the list of the cells that the terminal equipment has visited. For example, the terminal device sequentially records the identities of the 16 serving cells that it has recently visited in chronological order. Among them, the serving cell may be a new radio (NR) cell or an evolved unified terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA) cell, and the cell identifier may be a physical cell identifier (PCI). ) Or Cell Global Identifier (CGI).

To solve the problems mentioned in the background art, based on the network architecture shown in FIG. 1, as shown in FIG. 2, an embodiment of the present application provides a communication method. This method can be executed by terminal devices or components (such as chips, circuits, etc.) on the terminal device side; on the network side, it can be executed by network devices or components (such as chips, circuits, etc.) used for network devices . For ease of description, the following takes the terminal device and the network device to execute the method as an example for description.

The method includes the following steps:

Step 201: The terminal device generates first information, the first information includes identification information of the first RNA and second information, and the second information is used to determine the time information of the terminal device in the first RNA.

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 stay time is too long, the stay time is too short, and the stay time is normal. For another example, the time information includes: the stay time is too long, the stay time is longer, the stay time is normal, the stay time is short, the stay time is too short, and so on.

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

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

As an implementation method, the identification information of the first RNA includes the identification of the first RNA. That is, through the identification of an RNA, an RNA is uniquely identified.

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 (that is, the tracking area identity (TAI)) ). That is, through an RNA identification and a TAI, an RNA is uniquely identified.

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. Correspondingly, the network device can receive the second indication information.

Step 203: The network device sends third instruction information to the terminal device, where the third instruction information is used to instruct the terminal device to send the first information. Correspondingly, the terminal device can receive the third indication information.

The above steps 202 and 203 are optional steps.

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

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

The embodiment of the present application does not limit the specific implementation manner in which the network device adjusts the first RNA according to the first information. As an example, the method for the network device to adjust the first RNA according to the first information may include:

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

For example, when the time information includes: the stay time is too long, the stay time is normal, and the stay time is too short. If the network device determines that the stay time of the terminal device in the first RNA is too long according to the second information, the range of the first RNA is reduced, for example, the number of cells in the first RNA is reduced to reduce the range of the first RNA. If the network device determines that the stay time 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 to increase the range of the first RNA.

For another example, when the time information includes: the stay time is too long, the stay time is longer, the stay time is normal, the stay time is short, and the stay time is too short. If the network device determines that the stay time of the terminal device in the first RNA is too long or the stay time is longer 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 The range is reduced, wherein when the staying time is too long, the range of the first RNA is reduced more than when the staying time is longer. If the network device determines that the length of stay of the terminal device in the first RNA is too short or the length of stay is shorter according to the second information, the range of the first RNA is increased, for example, the number of cells in the first RNA is increased so that the length of the first RNA is The range is increased, wherein the increase in the range of the first RNA when the staying time is too short is greater than the increase in the range of the first RNA when the staying time is short.

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, and details are not described herein again.

Method 2: The above-mentioned first information further includes mobility status information and/or movement speed information of the terminal device, and the network device according to the second information in the first information and the mobility status information and/or movement speed information of the terminal device, Adjust the first RNA.

That is, the network device adjusts the first RNA according to the second information and the mobility status information of the terminal device. Or, the network device adjusts the first RNA according to the second information and the movement speed information of the terminal device. Alternatively, the network device adjusts the first RNA according to the second information, the mobility status information of the terminal device, and the movement speed information of the terminal device.

Among them, the mobility state of the terminal device (mobility state) is used to indicate the frequency of the terminal device changing the serving cell. For example, when the number of times the terminal device changes the serving cell within the 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 serving cell within the 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 serving cell within the set time period is less than or equal to the preset second number threshold, the mobility state of the terminal device is normal mobility.

In the embodiment of the present application, the mobility status information in the first information may include the mobility status of the terminal device when the first information is generated and/or the average mobility status of the terminal device in the first RNA.

Wherein, the moving speed information of the terminal device is used to indicate the moving speed (speed) of the terminal device.

In the embodiment of the present application, the moving speed information in the first information includes the moving speed of the terminal device when the first information is generated and/or the average moving speed of the terminal device in the first RNA.

For the second method, taking the time information including: the stay time is too long, the stay time is normal, and the stay 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 terminal device is in the first RNA according to the second information The stay time in the RNA is too long, and the terminal device is determined to be highly mobile according to the mobility status information and/or the movement speed of the terminal device is determined to be greater than or equal to the first speed threshold according to the movement speed information, then the first RNA is reduced Range, for example, reducing the number of cells in the first RNA reduces the range of the first RNA. Or, if the network device determines that the length of stay of the terminal device in the first RNA is too short based on the first information, and determines that the terminal device is low mobility based on the mobility status information and/or determines the movement of the terminal device based on the movement speed information If the speed is less than or equal to the second speed threshold, the range of the first RNA is increased, such as increasing the number of cells in the first RNA to increase the range of the first RNA.

For the second method above, in addition to referring to the length of stay of the terminal device in the first RNA, the network device also refers to the movement status information and/or movement 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 or a slow moving speed, if the terminal device stays in the first RNA for too long, the network device can determine that the range of the first RNA is not It is really too large, but because the terminal itself moves slowly and the stay time in the first RNA is too long, it is considered that there is no need to adjust the range of the first RNA, so that a better setting of the RNA range can be achieved.

Based on the embodiment corresponding to FIG. 2, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the status of the terminal device staying in the RNA. After the network device receives the RNA information reported by the terminal device, it can know which RNA has the abnormal terminal device residence time, and then determine whether the size of a certain RNA is set reasonable, for example, if the terminal device stays in a certain RNA If the duration is too long, it means that the RNA range may be too large, which can reduce the RNA range. Conversely, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too small, and the RNA range can be increased. In this way, it is possible to set a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and network equipment.

A variety of different implementation methods of the first information and the second information in the foregoing embodiment are given below.

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.

For example, the time information includes: the stay time is too long, the stay time is too short, and the stay time is normal. For another example, the time information includes: the stay time is too long, the stay time is longer, the stay time is normal, the stay time is short, the stay time is too short, and so on.

Implementation method 2: The second information includes the length of stay of the terminal device in the first RNA.

Implementation method three, the second information includes the timestamp of the terminal device entering the first RNA and the timestamp of leaving the first RNA.

For any one of the foregoing implementation method 1 to implementation method 3, optionally, before step 201, the terminal device may receive at least one set of duration thresholds from the network device, and each set of duration thresholds includes at least one duration threshold. Optionally, if two or more duration thresholds are received, the terminal device selects an appropriate set of thresholds according to its own mobility (such as mobility status information and/or movement 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, where the first duration threshold is greater than or equal to the second duration threshold), the two duration thresholds can be divided Three stay duration intervals are obtained, so the time information can be divided into: stay duration is too short (when stay duration is less than or equal to the second duration threshold), stay duration is normal (when stay duration is less than the first duration threshold and greater than the second duration Threshold), the stay duration is too long (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, so the time information can be divided into: stay time is too short, stay time is short, The stay time is normal, the stay time is long, and the stay time is too long. By analogy, not repeat them.

Taking the selected set of duration thresholds including two duration thresholds (respectively the first duration threshold and the second duration threshold) as an example, the first duration threshold is greater than or equal to the second duration threshold, and the first duration threshold is used to determine whether the terminal device is Whether the staying time in the first RNA is too long, and the second time-length threshold is used to judge whether the staying time 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, then 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 aforementioned first RNA. information. Or, 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 first information.

Optionally, the foregoing at least one set of duration thresholds may be configured for the terminal device in any of the following ways: System Information (SI), RRC release message, and RRC connection release message.

Implementation method 4: The second information includes the time stamp when the terminal device triggers the RNA update process.

That is, the implementation method is to record the RNA information (such as the above-mentioned first information) every time the terminal device triggers the RNA update (ie RNAU) process. The RNAU process can be triggered when the terminal device leaves the first RNA, or can be triggered when the cycle of RNAU arrives. Therefore, the network device can determine the length of stay of the terminal device in the first RNA from the multiple pieces of RNA information received.

Optionally, the terminal device records RNA information only once when the terminal device leaves a certain RNA (such as the first RNA). When the terminal device leaves the RNA, it means that the terminal device triggers the RNAU process and the RNA changes.

Implementation method five, the second information includes the timestamp when the terminal device records the MHI.

That is, the implementation method is that each time the terminal device records the MHI, the RNA information (that is, the above-mentioned first information) is incidentally recorded in the MHI. Wherein, the terminal device may record the MHI once every time it leaves the cell.

Optionally, if the terminal device does not leave the first RNA when the terminal device records the MHI, the terminal device does not record the RNA information in the MHI. Or it can be understood that when the terminal device needs to record MHI, if the terminal device just leaves a certain RNA (such as the first RNA), the terminal device can record a piece of RNA information (such as the first information above) in the MHI when recording the MHI.

Optionally, in combination with any one of the foregoing implementation method 1 to implementation method 5, the mobility status information and/or movement speed information of the terminal device may also be carried in the foregoing first information. The details are as described above. Go into details again.

As an implementation method, in combination with any of the foregoing embodiments, the network device may also send configuration parameters to the terminal device before step 201. The configuration parameters include one or more of the following: recording time length, recording time range, maximum recording item The quantity, the maximum storage capacity of the record item, and the effective area of the record. Among them, the configuration method can be:

It is sent to the terminal equipment through the system information broadcast, or through the RRC release message, or sent to the terminal equipment through the 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 suspends or stops recording RNA information:

Condition 1: The terminal equipment reaches the recording time length;

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

Condition 3: The terminal equipment reaches the maximum number of recorded items;

Condition 5: The terminal device leaves the effective area of the record.

The effective area may be composed of a cell or RNA or tracking area, or may be an actual geographic area (for example, an area defined by coordinates or latitude and longitude).

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

As another implementation method, when the terminal device leaves the RRC inactive state, the terminal device suspends or stops recording RNA information. Among them, the terminal device leaving the RRC inactive state includes: the terminal device enters the RRC idle state (RRC_IDLE), or the RRC connection (RRC_CONNECTED) state, or the terminal device reselects to an inter-radio access technology (RAT) cell Or the terminal device has entered the "camped on any cell" state (that is, out-of-coverage).

That is, after the terminal device determines to suspend or stop recording RNA information, it will not generate RNA information similar to the above-mentioned first information.

As an implementation method, in combination with any of the foregoing embodiments, before step 201, the terminal device may also receive instruction information (may be referred to as fifth instruction information) for instructing to enable the RNA information recording function from the network device, so that the terminal device Perform the above step 201 to start recording RNA information.

As an implementation method, when the implementation method of the foregoing second information is any one of implementation method 1 to implementation method 4, and the foregoing step 202 and step 203 are performed, the second instruction information of the foregoing step 202 can be carried in the RRC recovery Request (RRCResumeRequest) message, or RRC setup request (RRCSetupRequest) message, or RRC connection recovery request (RRCConnectionResumeRequeste) message, or RRC connection request (RRCConnectionRequest) message, or RRC recovery complete (RRCResumeComplete) message, or RRC setup complete (RRCSetupComplete) Message, or RRC Connection Resume Complete (RRCConnectionResumeComplete) message, or RRC Connection Setup Complete (RRCConnectionSetupComplete) message, or RRC Reconfiguration Complete (RRCReconfigurationComplete) message, the third indication information in step 203 above may be carried in the UE Information Request (UE Information Request) ) Message, or RRC resume (RRCResume) message, or RRC setup (RRCSetup) message, or RRC connection resume (RRCConnectionResumeRequeste) message, or RRC connection setup (RRCConnectionSetup) message, or RRC reconfiguration (RRCReconfiguration) message, the above step 204 The first information may be carried in a UE information response (UE information Response) message, or RRC recovery request message, or RRC establishment request message, or RRC connection recovery request message, or RRC connection request message, or RRC recovery complete message, or RRC establishment Complete message, or RRC connection recovery complete message, or RRC connection establishment complete message, or RRC reconfiguration complete message. It should be noted that in a reporting process, the messages of 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. The RRC recovery request message, for example, can be carried in a UE information response message, or an RRC recovery complete message, or an RRC establishment complete message, or an RRC reconfiguration complete message.

As an implementation method, when the implementation method of the foregoing second information is any one of implementation method 1 to implementation method 4, and the foregoing step 202 and step 203 are not performed, the first information of the foregoing step 204 can be carried in the UE information Response message, or RRC recovery request message, or RRC establishment request message, or RRC connection recovery request message, or RRC connection request message, or RRC recovery complete message, or RRC establishment complete message, or RRC connection recovery complete message, or RRC connection Setup complete message, or RRC reconfiguration complete message.

As an implementation method, when the implementation method of the foregoing second information is implementation method 5, that is, the first information is reported through MHI, the MHI reporting method in the prior art can be used for reporting the first information in the embodiment of this application. MHI reports.

It should be noted that in this embodiment of the application, the terminal device can record one or more RNA messages before the RNA message transmission time point arrives. Of course, if the trigger condition for pausing or stopping recording RNA information is met, the terminal device will pause Or stop recording RNA information. When the time point for sending the RNA information arrives, the terminal device sends one or more recorded RNA information to the network device. Wherein, 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 when the RRC recovery message is sent is the time when the RNA information is sent.

Therefore, in this embodiment of the present application, in the above step 204, the terminal device may send multiple pieces of RNA information to the network device, including the above first information.

In the following, the process shown in FIG. 2 will be introduced and explained with reference to the specific examples shown in FIG. 3 to FIG. 5.

As shown in FIG. 3, it is a schematic flowchart of another communication method provided by an embodiment of this application. This method corresponds to the implementation method 1 to the implementation method 3 of the second information in the embodiment corresponding to FIG. 2 above. This embodiment introduces a duration threshold. The terminal device judges the time information in the RNA according to the duration threshold, and records the UE's RNA information when the stay duration is abnormal (ie, too long, or too short, or long, or short, etc.).

The method includes the following steps:

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

Wherein, each group of duration thresholds includes at least one duration threshold.

As an implementation method, the duration threshold can be set in consideration of 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, high, normal, and low, three sets of corresponding duration thresholds are configured for these three mobility states, and each set 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, for different moving speeds, a corresponding group number of duration thresholds are configured, and each group of duration thresholds includes at least one duration threshold.

If the UE receives two or more duration thresholds, the terminal device selects an appropriate set of thresholds according to its own mobility (such as mobility status information and/or moving speed information).

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

Step 302: The terminal device generates an RNA message.

Specifically, when the terminal device leaves a certain RNA (such as the first RNA), the terminal device determines the presence of the terminal device’s stay in the first RNA according to a set of duration thresholds selected from at least one set of received duration thresholds If it is abnormal, the terminal device generates the above-mentioned RNA information. Wherein, the terminal device judges whether there is an abnormality in the stay time length by judging the relationship between the stay time length T in the first RNA and the selected set of time length thresholds. Taking the selected set of duration thresholds including two duration thresholds (respectively the first duration threshold TH1 and the second duration threshold TH2 as an example, where TH1 is greater than or equal to TH2) as an example, if the stay duration T is greater than or equal to TH1, or T If it is less than or equal to TH2, the terminal device determines that the stay time is abnormal (including the stay time is too long or the stay time is too short), and the terminal device generates an RNA message. Among them, the terminal device leaving a certain RNA can also be referred to as triggering the RNAU process and the RNA changes.

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

1) The identification of the first RNA;

2) The identification of the tracking area to which the first RNA belongs (ie TAI);

3) The time information of the terminal device staying in the first RNA, for example, can be any one or more of the following:

a) An indication information (may be called the first indication information), which is used to indicate the time information of the terminal device in the first RNA.

Taking the selected set of duration thresholds including two duration thresholds (respectively the first duration threshold TH1 and the second duration threshold TH2 as an example, 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 time T is too long. When the stay time T is less than or equal to TH2, the first indication information is used to indicate that the stay time T is too short. For example, the first indication information being 1'means that T is greater than or equal to TH1, and the first indication information being '0' that T is less than or equal to TH2; or, the first indication information being 0'that T is greater than or equal to TH1, and the first indication is The information as '1' means that T is less than or equal to TH2.

b) The residence time T of the terminal device in the first RNA;

c) The time stamp of the terminal device entering and leaving the first RNA;

4) The mobility status and/or moving speed of the terminal equipment;

Wherein, the mobility state may be the mobility state of the terminal device when the RNA information is recorded, or it may be the average mobility state of the terminal device in the first RNA. The moving speed may be the moving speed of the terminal device during RNA information recording, or the average moving speed of the terminal device in the first RNA.

5) The cell identity when the terminal device enters and/or leaves the first RNA;

Among them, the cell identity can be PCI or CGI.

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 is far away from the cell when it leaves the first RNA, the network device considers that the length of stay of the terminal device in the first RNA is of reference value, and therefore can adjust the first RNA according to the length of stay. The size of RNA. When the cell when the terminal device enters the first RNA is close to the cell when it leaves the first RNA, the network device considers that the length of time the terminal device stays in the first RNA has no reference value, and therefore may not adjust the first RNA temporarily. size.

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

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

Condition 1: The terminal equipment reaches the recording time length;

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

Condition 5: The terminal device leaves the effective area of the record.

Among them, the recording time length, the recording time range, the maximum number of recording items, the maximum storage capacity of the recording items, and the effective area can be collectively referred to as configuration parameters. The configuration parameters can be sent by the network device to the terminal device before step 302 above. . The configuration method may be: sending to the terminal device through system information broadcast, or through an RRC release message, or sending to the terminal device through an RRC connection release message.

As another implementation method, when the terminal device leaves the RRC inactive state, the terminal device suspends or stops recording RNA information.

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

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

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.

The above steps 304 to 304 are optional steps.

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

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

For the specific implementation manner of this step, reference may be made to the related description of step 204 in the embodiment corresponding to FIG. 2, and details are not described herein again.

Based on the foregoing embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the status of the terminal device staying in the RNA. After the network device receives the RNA information reported by the terminal device, it can know which RNA has the abnormal terminal device residence time, and then determine whether the size of a certain RNA is set reasonable, for example, if the terminal device stays in a certain RNA If the duration is too long, it means that the RNA range may be too large, which can reduce the RNA range. Conversely, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too small, and the RNA range can be increased. In this way, it is possible to set a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and network equipment.

As shown in FIG. 4, it is a schematic flowchart of another communication method provided by an embodiment of this application. This method corresponds to the fourth implementation method of the second information in the embodiment corresponding to FIG. 2 above. In this embodiment, the terminal device records the RNA information every time the RNAU process is triggered.

The method includes the following steps:

In step 401, the terminal device generates an RNA message each time the RNAU process is triggered, and the RNA message includes the RNA information of the first RNA, specifically including one or more of the following 1) to 5):

1) Identification of the first RNA.

2) The identification of the tracking area to which the first RNA belongs (ie, TAI).

3) The timestamp when the terminal device triggers the RNAU process, or the length of stay in the first RNA when the terminal device triggers the RNAU process.

4) The mobility status and/or moving speed of the terminal device.

5) The cell identification when the terminal device enters and/or leaves the first RNA.

Among them, the cell identity can be PCI or CGI.

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 stay of the terminal device in the first RNA, or the terminal device directly reports that it is in the first RNA when it leaves the first RNA The length of stay. Therefore, optionally, the aforementioned RNAU triggering process may 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 will not generate RNA information when triggering the RNAU process this time.

Among them, the terminal device leaving a certain RNA can also be referred to as triggering the RNAU process and the RNA changes.

For steps 402 to 406, and steps 303 to 307 of the embodiment corresponding to FIG. 3, reference may be made to the foregoing description and will not be repeated.

Based on the foregoing embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the status of the terminal device staying in the RNA. After the network device receives the RNA information reported by the terminal device, it can calculate the length of stay of the terminal device in the RNA according to the reported timestamp that triggered the RNAU process, or the terminal device directly reports the length of stay in the RNA, and then the network device Determine whether the terminal device has an abnormal staying time problem, and then determine whether the size of the RNA is set 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 can be reduced. Small RNA range. Conversely, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too small, and the RNA range can be increased. In this way, it is possible to set a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and network equipment.

It should be noted that the main difference between the embodiment corresponding to Fig. 4 and the embodiment corresponding to Fig. 3 is: in the real-time corresponding to Fig. 3, the terminal device reports abnormal RNA information, and the network device can directly know which RNA may exist. Problem, and then adjust the RNA size. In the embodiment corresponding to FIG. 4, 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 size of the RNA.

As shown in FIG. 5, it is a schematic flowchart of another communication method provided by an embodiment of this application. This method corresponds to the fifth implementation method of the second information in the embodiment corresponding to FIG. 2 above. This embodiment considers enhancing the existing MHI, and the terminal device adds RNA information to the MHI while recording the MHI.

The method includes the following steps:

In step 501, each time the terminal device records MHI, it adds RNA information to the MHI. The RNA information includes the RNA information of the first RNA, specifically including one or more of the following 1) to 4):

1) Identification of the first RNA.

3) The timestamp at which the terminal device records the RNA information, or the current stay time of the terminal device in the first RNA.

Among them, the time stamp when the terminal device records the RNA information can also be understood as the time stamp when the terminal device records the MHI.

4) The mobility status and/or moving speed of the terminal equipment;

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 stay of the terminal device in the first RNA, or the terminal device directly reports that it is in the first RNA when it leaves the first RNA The length of stay. Therefore, optionally, when the terminal device records the MHI, if the current RNA of the terminal device has not changed, 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 above-mentioned first RNA), the terminal device records the RNA information in the MHI while recording the MHI.

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

This step is the same as step 303 in the embodiment corresponding to FIG. 3, and reference may be made to the foregoing description, and details are not repeated.

This step is optional.

Step 503: The terminal device sends the MHI containing RNA information to the network device.

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

For the specific implementation of this step, reference may be made to the related description of step 307 in the embodiment corresponding to FIG. 3, and details are not described herein again.

Based on the foregoing embodiment, the terminal device in the RRC inactive state records the information of the RNA it has experienced, including information that can reflect the status of the terminal device staying in the RNA. After the network device receives the RNA information reported by the terminal device, it can calculate the length of stay of the terminal device in the RNA according to the reported timestamp of the recorded RNA information, and then the network device determines whether the terminal device has an abnormal stay length problem, and then Determine whether the size of the RNA is set 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. Conversely, if the terminal device stays in a certain RNA for too long, it means that the RNA range may be too small, and the RNA range can be increased. In this way, it is possible to set a suitable RNA range for the terminal device, which helps to reduce the overhead of the terminal device and network equipment.

It should be noted that the main difference between the embodiment corresponding to FIG. 5 and the embodiment corresponding to FIG. 4 is: in the embodiment corresponding to FIG. 5, the terminal device carries RNA information in the reported MHI, while the embodiment corresponding to FIG. 4 is Record RNA information when the RNAU process is triggered, and then report one or more recorded RNA information after the reporting time point arrives.
