Description

Communication method, device and system

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method, device and system.

Background

A Radio Access Network (RAN) -based Notification Area (RNA) is composed of one or more cells (cells). The terminal device in a Radio Resource Control (RRC) INACTIVE (RRC _ INACTIVE) state may be configured with RNA by the last serving base station. The RAN side knows the RNA to which the terminal device belongs, so when the RAN side initiates paging to a terminal device in 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 arrangement of RNA belongs to the network planning problem, and the arrangement of RNA needs to be reasonable. If the RNA range is set to be too large, that is, one RNA includes more cells, the RAN needs to page more cells when paging a certain terminal device, resulting in higher paging overhead of the network. If the RNA range is set too small, i.e. one RNA contains fewer cells, the terminal device triggers more RNA Update (RNAU) procedures due to frequent entering or leaving of the RNA, resulting in a higher terminal device overhead.

Currently, the actual network situation is generally obtained through manual testing, and then RNA is planned according to the actual network situation and the deployment of the network. However, once the RNA is planned, the RNA is not changed, but in reality, the RNA is not necessarily set properly (e.g. too large or too small range), which causes a large overhead for the network or the terminal device.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings. The particular methods of operation in the method embodiments may also be applied to apparatus embodiments or system embodiments. In the description of the present application, the term "plurality" means two or more unless otherwise specified.

Fig. 1 is a schematic diagram of a network architecture applicable to the embodiment of the present application, and includes a terminal device and a network device. The terminal device communicates with the network device via a wireless interface.

A terminal device (terminal device), which is a device with a wireless transceiving function, can be deployed on land, including indoors or outdoors, and is handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), a user equipment (user equipment, UE), and the like.

The network device is a device for providing a wireless communication function for a terminal device, and the network device includes but is not limited to: RAN equipment (next generation base station (gNB), evolved node B (eNB), etc.), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved node B, or home node B, HNB), Base Band Unit (BBU), transmission point (TRP), Transmission Point (TP), mobile switching center (msc), etc. For convenience of description, in the embodiments of the present application, a network device is taken as an example for description.

For the purpose of understanding the embodiments of the present application, some terms will be described below.

First, RNA

RNA consists of one or more cells (cells). The terminal device in a Radio Resource Control (RRC) INACTIVE state (RRC _ INACTIVE) may be configured with RNA by the last serving base station. The RAN side knows the RNA to which the terminal device belongs, so when the RAN side initiates paging to a terminal device in RRC _ INACTIVE state, the RAN will first page the terminal device within the range of the RNA to which the terminal device belongs.

Second, RAN-based Notification Area Update (RNAU)

The RNAU procedure is a terminal device triggered procedure that synchronizes RNA information to the RAN. The basic flow of the process is that the terminal device sends an RRC recovery message (RRCResumeRequest message) or an RCC connection recovery message (rrcconnectionresuquest message) to the RAN device, and a recovery cause value field (resumeCause) in the message is set to 'RNA-Update', and then the RAN device can know that the terminal device currently triggers an RNA Update process after receiving the message, and then the RAN device can execute the relevant operation of the RNAU process.

The RAN may not be informed when the terminal device moves within the RNA range, and when the terminal device leaves the current RNA range, the RNAU process may be triggered to inform the RAN device: the current RNA of the terminal device has changed.

In addition, in order to maintain the RNA, the terminal device may also periodically initiate an RNAU procedure, specifically, when the terminal device enters an RRC _ INACTIVE state, the terminal device starts a timer T380, and after the T380 expires, the terminal device needs to initiate the RNAU procedure to perform information synchronization of the RNA with the RAN device, regardless of whether the current RNA of the terminal device changes.

Third, Moving History Information (MHI)

The MHI is recorded information about the historical movement of the terminal device, and the specific content of the MHI is a list of cells that the terminal device has visited. For example, the terminal device records the identifiers of the 16 serving cells that it has visited last in sequence in time order. The serving Cell may be a New Radio (NR) Cell or an Evolved Universal Terrestrial Radio Access (E-UTRA) Cell, and the Identifier of the Cell may be a Physical Cell Identifier (PCI) or a 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. The method is carried out by the terminal equipment or a component (such as a chip, a circuit and the like) used for the terminal equipment on the terminal equipment side; on the network side, this may be performed by the network device or a component (e.g., a chip, a circuit, etc.) for the network device. For convenience of explanation, the following description will be given taking as an example that the terminal device and the network device execute the method.

The method comprises the following steps:

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

The first information may also be referred to as RNA information, and is used to record identification information of a first RAN where the UE is located and time information of the UE in the first RNA. The second information is used for recording the time information of the UE in the first RNA. For example, the time information includes: the stay time is too long, too short and normal. For another example, the time information includes: too long a dwell time, longer dwell time, normal dwell time, shorter dwell time, too short dwell time, and the like.

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

The first RNA may be an RNA in which the terminal device is located, the RNA comprising one or more cells.

As one implementation, the identification information of the first RNA includes an identification of the first RNA. I.e., an RNA is uniquely identified by its identity.

As another implementation method, the identification information of the first RNA includes an identification of the first RNA and an identification of a Tracking Area (TA) to which the first RNA belongs (i.e., a Tracking Area Identification (TAI)). I.e. an RNA is uniquely identified by an RNA identification and a TAI.

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 records the first information. Accordingly, the network device may receive the second indication information.

Step 203, the network device sends third indication information to the terminal device, where the third indication information is used to indicate the terminal device to send the first information. Accordingly, the terminal device may 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. Accordingly, the network device may 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 of the network device adjusting 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:

in the first method, the network device adjusts the first RNA according to the second information in the first information.

For example, the time information includes: too long a dwell time, normal dwell time and too short a dwell time. If the network device determines that the terminal device stays in the first RNA for 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 so that the range of the first RNA is reduced. If the network device determines that the residence 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, for example, the number of cells in the first RNA is increased so that the range of the first RNA is increased.

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 shorter, and the stay time is too short. If the network device determines that the residence time of the terminal device in the first RNA is too long or the residence time is 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 so that the range of the first RNA is reduced, where a reduction range of the first RNA when the residence time is too long is larger than a reduction range of the first RNA when the residence 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, for example, the number of cells in the first RNA is increased so that the range of the first RNA is increased, where the range of the first RNA is increased by a larger extent when the dwell time is too short than when the dwell 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, which is not described again.

And the network equipment adjusts the first RNA according to the second information in the first information and the mobility state information and/or the moving speed information of the terminal equipment.

That is, the network device adjusts the first RNA according to the second information and the mobility state information of the terminal device. Or the network device adjusts the first RNA according to the second information and the moving speed information of the terminal device. Or the network equipment adjusts the first RNA according to the second information, the mobility state information of the terminal equipment and the moving speed information of the terminal equipment.

The mobility state (mobility state) of the terminal device is used to indicate the frequency of changing the serving cell by the terminal device. For example, when the number of times that the terminal device changes the serving cell within the set time length is greater than or equal to the preset first time threshold, the mobility state of the terminal device is high mobility. And when the times of replacing the service cell by the terminal equipment within the set time length is less than the preset first time threshold and greater than the preset second time threshold, the mobility state of the terminal equipment is medium mobility. And when the number of times of changing the service cell of the terminal equipment in the set time length is less than or equal to the preset second time threshold value, the mobility state of the terminal equipment is normal mobility.

In this embodiment, the mobility state information in the first information may include a mobility state of the terminal device when generating the first information and/or an average mobility state of the terminal device within the first RNA.

The moving speed information of the terminal device is used to indicate a moving speed (speed) of the terminal device.

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

Aiming at the second method, the time information comprises: for example, if the length of the stay is too long, the length of the stay is normal, and the length of the stay is too short, the method for the network device to adjust the first RNA includes: 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, and determines that the terminal device is high mobility 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, the range of the first RNA is reduced, for example, the number of cells in the first RNA is reduced so that the range of the first RNA is reduced. Or, if the network device determines that the stay 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 mobility 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, the range of the first RNA is increased, for example, the number of cells in the first RNA is increased so that the range of the first RNA is increased.

For the second method, the network device refers to the movement state information and/or the movement speed information of the terminal device in addition to the stay time of the terminal device in the first RNA, so as to more accurately judge whether the range of the first RNA is actually too large or too small. For example, for a terminal device whose moving state is low mobility or whose moving speed is slow, if the staying time of the terminal device in the first RNA is too long, the network device may determine, according to the second method, that the range of the first RNA is not really too large, but the staying time in the first RNA is too long due to the terminal moving slowly, so that it is considered that the range of the first RNA does not need to be adjusted, and thus, a better setting of the range of the RNA may be achieved.

Based on the corresponding embodiment of fig. 2, the terminal device in the RRC inactive state records the information of the RNA experienced by itself, including the information capable of representing the staying condition of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device may know which RNAs have the problem of abnormal terminal device retention time, and further determine whether the size setting of a certain RNA is reasonable, for example, if the terminal device has too long retention time in a certain RNA, it indicates that the RNA range may be too large, and further, the RNA range may be reduced. Conversely, if the terminal device stays in a certain RNA for too short a time, it indicates that the RNA range may be too small, and the RNA range may be increased. Therefore, the proper RNA range is set for the terminal equipment, and the cost of the terminal equipment and the network equipment is reduced.

A plurality of different implementation methods of the first information and the second information in the above embodiments are given below.

The first implementation method includes that the second information includes first indication information, and the first indication information is used for indicating time information of the terminal device in the first RNA.

For example, the time information includes: the stay time is too long, too short and normal. For another example, the time information includes: too long a dwell time, longer dwell time, normal dwell time, shorter dwell time, too short dwell time, and the like.

And in the second implementation method, the second information comprises the stay time of the terminal equipment in the first RNA.

And the second information comprises a timestamp (timestamp) of the terminal device entering the first RNA and a timestamp of the terminal device leaving the first RNA.

For any one of the first to third implementation methods, optionally, before the step 201, the terminal device may receive at least one group of duration thresholds from the network device, where each group of duration thresholds includes at least one duration threshold. Optionally, if two or more sets of duration thresholds are received, the terminal device selects an appropriate set of thresholds according to its mobility (e.g., mobility state information and/or mobility speed information). For example, when the selected group of duration thresholds includes two duration thresholds (e.g., 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 may be divided into three dwell duration intervals, so that the time information may be divided into: too short a dwell period (when the dwell period is less than or equal to the second period threshold), normal dwell period (when the dwell period is less than the first period threshold and greater than the second period threshold), too long dwell period (when the dwell period is greater than or equal to the first period threshold). For another example, when the selected group of duration thresholds includes four duration thresholds, the four duration thresholds may be divided into five stay duration intervals, so that the time information may be divided into: too short a dwell time, short dwell time, normal dwell time, long dwell time. Therefore, the descriptions of such operations are omitted.

Taking the example that the selected group of duration thresholds includes two duration thresholds (a first duration threshold and a second duration threshold, respectively), 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 the terminal device staying in the first RNA is too long, and the second duration threshold is used to determine whether the duration of the terminal device staying in the first RNA is too short. When the terminal device leaves the first RNA, if the stay time length in the first RNA is determined to be larger than or equal to the first time length threshold value, the stay time length of the terminal device in the first RNA is determined to be too long, and the terminal device is triggered to generate the first information. Or, when the terminal device leaves the first RNA, if it is determined that the staying time in the first RNA is less than or equal to the second time threshold, it is determined that the staying time in the first RNA of the terminal device is too short, and the terminal device is also triggered to generate the first information.

Optionally, the at least one group of duration thresholds may be configured to the terminal device in any of the following manners: system Information (SI), RRC release message, RRC connection release message.

And the second information comprises a timestamp when the terminal equipment triggers the RNA updating process.

That is, the implementation method is that the terminal device records the RNA information (such as the first information) once each time the terminal device triggers the RNA update (i.e., RNAU) process. The RNAU procedure may be triggered when the terminal device leaves the first RNA, or when the period of the RNAU arrives. Therefore, the network device can determine the stay time of the terminal device in the first RNA from the received information of the plurality of RNAs.

Alternatively, the terminal device may record the RNA information only once when the terminal device leaves a certain RNA (e.g., the first RNA). Leaving the RNA by the terminal device means that the terminal device triggers the RNAU process and the RNA changes.

And the second information comprises a time stamp when the terminal equipment records the MHI.

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

Optionally, when the terminal device records the MHI, if the terminal device does not leave the first RNA, the terminal device does not record RNA information in the MHI. Or, it is understood that when the terminal device needs to record the MHI, if the terminal device just leaves a certain RNA (e.g. the first RNA), the terminal device can record an RNA information (e.g. the first information) in the MHI when recording the MHI.

Optionally, in combination with any one of the first to fifth implementation methods, the mobility state information and/or the moving speed information of the terminal device may also be carried in the first information, which is specifically described above and is not described herein again.

As an implementation method, in combination with any of the above embodiments, the network device may further send, to the terminal device, configuration parameters before step 201, where the configuration parameters include one or more of the following: length of recording time, recording time range, maximum number of entries, maximum storage capacity of entries, effective area of recording. The configuration mode may be:

the system information is broadcast, or the RRC release message is sent to the terminal equipment, or the RRC connection release message is sent to the terminal equipment. Therefore, when the terminal device determines at any time that one or more of the following conditions are satisfied, then the terminal device pauses or stops recording RNA information:

and a second condition: the terminal equipment leaves the recording time range;

and (3) carrying out a third condition: the terminal device reaches the maximum number of the record items;

and a fifth condition: the terminal device leaves the recorded active area.

The active area may consist of cells or RNA or tracking areas, but may also be an actual geographical area (e.g. an area defined by coordinates or latitude and longitude).

As still 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 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 the RNA information. Wherein the terminal device leaving the RRC inactive state includes: the terminal device enters an RRC IDLE state (RRC _ IDLE), an RRC CONNECTED state (RRC _ CONNECTED), or a terminal device reselects to an inter-Radio Access Technology (RAT) cell, or the terminal device enters a "mapped on any cell" state (i.e., out-of-coverage).

That is, after the terminal device determines to pause or stop recording the RNA information, the RNA information similar to the first information described above will not be generated.

As an implementation method, in combination with any of the above embodiments, before step 201, the terminal device may further receive, from the network device, indication information (which may be referred to as fifth indication information) for indicating to start an RNA information recording function, so that the terminal device performs step 201, namely starts to record RNA information.

As an implementation method, when the implementation method of the second information is any one of implementation methods one to four, and the step 202 and the step 203 are executed, the second indication information of the step 202 may be carried in an RRC recovery Request (rrcresumererequest) message, an RRC establishment Request (RRCSetupRequest) message, an RRC connection recovery Request (RRCConnectionRequest) message, an RRC connection completion (RRCConnectionRequest) message, an RRC recovery completion (RRCResumeComplete) message, an RRC setup completion (RRCSetupComplete) message, an RRC connection recovery completion (rrcconnectioncomplete) message, an RRC connection setup completion (rrcconnectioncomplete) message, an RRC connection completion (rrcconnectioncomplete) message, an RRC reconfiguration (rrcconnectioncomplete) message, or an RRC reconfiguration (RRCConnectionRequest) message, an RRC reconfiguration message, or an RRC reconfiguration message, and the third indication information of the step 203 may be carried in an RRC connection Request (RRCConnectionRequest) message, an RRC connection Request (RRCConnectionRequest) message, an RRC message, or an RRC connection Request (RRCConnectionRequest) message, or an RRC connection Request (rrccontecomplete message, or an RRC reconfiguration message, or a RRC reconfiguration message (RRCConnectionRequest message, or a RRC reconfiguration message, or a response message, or a response message, or a response to indicate that the third indication of the, Or an RRC reconfiguration (RRC reconfiguration) message, the first information in step 204 may be carried in a UE information Response (UE information Response) message, an RRC recovery request message, an RRC establishment request message, an RRC connection recovery request message, an RRC connection request message, an RRC recovery completion message, an RRC establishment completion message, an RRC connection recovery completion message, an RRC connection establishment completion message, or an RRC reconfiguration completion message. It should be noted that, in a reporting process, the messages in the step 202 and the step 204 are different messages, for example, when the second indication information in the step 202 is carried in the RRC recovery request message, the first information in the step 204 is not carried in the RRC recovery request message, for example, the first information may be carried in a UE information response message, or an RRC recovery completion message, or an RRC setup completion message, or an RRC reconfiguration completion message.

As an implementation method, when the implementation method of the second information is any one of implementation methods one to four, and the step 202 and the step 203 are not executed, the first information of the step 204 may be carried in a UE information response message, an RRC recovery request message, an RRC establishment request message, an RRC connection recovery request message, an RRC connection request message, an RRC recovery completion message, an RRC establishment completion message, an RRC connection recovery completion message, an RRC connection establishment completion message, or an RRC reconfiguration completion message.

As an implementation method, when the implementation method of the second information is implementation method five, that is, the MHI reports the first information, the MHI carrying the first information in the embodiment of the present application may be reported according to a method of reporting the MHI in the prior art. Specifically, the second indication information of step 202 may be carried in an RRC recovery complete message, an RRC establishment complete message, an RRC connection recovery complete message, or an RRC connection establishment complete message, the third indication information of step 203 may be carried in a UE information request message, and the first information of step 204 may be carried in a UE information response message.

It should be noted that, in this embodiment of the application, the terminal device may record one or more pieces of RNA information before the sending time point of the RNA information arrives, and of course, if a trigger condition for suspending or stopping recording the RNA information is met, the terminal device suspends or stops recording the RNA information. When the sending time point of the RNA information arrives, the terminal equipment sends the recorded one or more RNA information to the network equipment. Wherein, the sending time point of the RNA information can be the sending time of the message carrying the RNA information. For example, if the RRC recovery message carries the recorded RNA information, the time point of sending the RRC recovery message is the sending time point of the RNA information.

Therefore, in this embodiment of the present application, in step 204, the terminal device may send a plurality of pieces of RNA information to the network device, where the plurality of pieces of RNA information include the first information.

The flow shown in fig. 2 will be described with reference to specific examples shown in fig. 3 to 5.

Fig. 3 is a schematic flow chart of another communication method provided in the embodiment of the present application. The method corresponds to the first to third implementation methods of the second information in the embodiment corresponding to fig. 2. The embodiment introduces a time length threshold, and the terminal device judges the time information in the RNA according to the time length threshold and records the RNA information of the UE when the stay time length is abnormal (i.e. too long, too short, longer, or shorter).

The method comprises the following steps:

step 301, the network device configures at least one group of duration thresholds to the terminal device.

Wherein each set of duration thresholds comprises at least one duration threshold.

As an implementation method, the setting of the duration threshold may consider 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 mobility state, normal mobility state and low mobility state, three sets of corresponding duration thresholds are configured for the three mobility states, and each set of duration thresholds includes at least one duration threshold. As another example, different time duration thresholds are set for different moving speeds. For example, assuming that the moving speeds have different values, corresponding sets of time duration thresholds are configured for different moving speeds, each set of time duration thresholds including at least one time duration threshold.

If the UE receives two or more sets of duration thresholds, the terminal device selects an appropriate set of thresholds according to its mobility (e.g., mobility state information and/or mobility speed information).

The configuration mode may be: the system information is broadcast, or the RRC release message is sent to the terminal equipment, or the RRC connection release message is sent to the terminal equipment.

Step 302, the terminal device generates an RNA message.

Specifically, when the terminal device leaves a certain RNA (e.g., a first RNA), the terminal device determines that the staying time of the terminal device in the first RNA is abnormal according to a group of time thresholds selected from the received at least one group of time thresholds, and then the terminal device generates the RNA information. And the terminal equipment judges whether the stay time length is abnormal or not by judging the size relation between the stay time length T in the first RNA and a selected group of time length threshold values. Taking the example that the selected set of duration thresholds includes two duration thresholds (the first duration threshold TH1 and the second duration threshold TH2, 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 is abnormal (including the duration is too long, or the duration is too short), and then the terminal device generates an RNA message. Wherein the terminal device leaving a certain RNA may also be referred to as triggering RNAU procedure and RNA changes.

The RNA information generated by the terminal equipment comprises RNA information of the first RNA, and specifically comprises one or more of the following items 1) to 5):

1) identification of the first RNA;

2) identification of the tracking region to which the first RNA belongs (i.e., TAI);

3) the information of the time that the terminal device stays in the first RNA may be, for example, any one or more of the following:

a) and the indication information (which can be called as first indication information) is used for indicating the time information of the terminal equipment in the first RNA.

Taking the example that the selected set of duration thresholds includes two duration thresholds (for example, a first duration threshold TH1 and a second duration threshold TH2, where TH1 is greater than or equal to TH2), when the duration T is greater than or equal to TH1, the first indication information is used to indicate that the duration T is too long, and when the duration T is less than or equal to TH2, the first indication information is used to indicate that the duration T is too short. For example, a first indication of 1 ' indicates that T is greater than or equal to TH1, and a first indication of ' 0 ' indicates that T is less than or equal to TH 2; alternatively, a first indication of 0 ' indicates that T is greater than or equal to TH1, and a first indication of ' 1 ' indicates that T is less than or equal to TH 2.

b) The retention time T of the terminal equipment in the first RNA;

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

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

the mobility state may be a mobility state of the terminal device at the time of recording the RNA information, or may be an average mobility state of the terminal device in the first RNA. The moving speed may be a moving speed of the terminal device at the time of recording the RNA information, or may be an average moving speed of the terminal device within the first RNA.

5) Cell identification when the terminal device enters and/or leaves the first RNA;

the cell identifier may be a 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 the terminal device leaves the first RNA, the network device considers that the stay time of the terminal device in the first RNA has a reference value, and thus the size of the first RNA can be adjusted according to the stay time. When the cell when the terminal device enters the first RNA is closer to the cell when the terminal device leaves the first RNA, the network device considers that the stay time of the terminal device in the first RNA has no reference value, so that the size of the first RNA can be temporarily not adjusted.

Step 303, the terminal equipment stops or suspends recording the RNA information.

This step is an optional step. The terminal equipment stops or suspends the recording of the RNA information when one or more of the following conditions are met:

and a second condition: the terminal equipment leaves the recording time range;

and a fifth condition: the terminal device leaves the recorded active area.

The length of the recording time, the range of the recording time, the maximum number of entries, the maximum storage capacity of the entries, and the effective area may be collectively referred to as configuration parameters, and the configuration parameters may be sent from the network device to the terminal device before the step 302. The configuration mode may be: the system information is broadcast, or the RRC release message is sent to the terminal equipment, or the RRC connection release message is sent to the terminal equipment.

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

Optionally, before step 302, the terminal device may further receive indication information (which may be referred to as fifth indication information) for indicating to turn on the RNA information recording function from the network device.

And step 304, the terminal device sends second indication information to the network device, so as to inform the network device that the RNA information is recorded at the terminal device.

Step 305, the network device sends third indication information to the terminal device, for instructing 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.

The specific implementation of this step may refer to the related description of step 204 in the corresponding embodiment of fig. 2, and is not described again.

Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA experienced by itself, including the information that can represent the staying condition of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device may know which RNAs have the problem of abnormal terminal device retention time, and further determine whether the size setting of a certain RNA is reasonable, for example, if the terminal device has too long retention time in a certain RNA, it indicates that the RNA range may be too large, and further, the RNA range may be reduced. Conversely, if the terminal device stays in a certain RNA for too short a time, it indicates that the RNA range may be too small, and the RNA range may be increased. Therefore, the proper RNA range is set for the terminal equipment, and the cost of the terminal equipment and the network equipment is reduced.

Fig. 4 is a schematic flow chart of another communication method provided in the embodiment of the present application. This method corresponds to the fourth implementation method of the second information in the embodiment corresponding to fig. 2. In this embodiment, the terminal device records RNA information once each time the RNAU process is triggered.

The method comprises the following steps:

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

1) identification of the first RNA.

2) Identification of the tracking region to which the first RNA belongs (i.e., TAI).

3) A timestamp (timestamp) when the terminal device triggers the RNAU process, or a length of stay within the first RNA when the terminal device triggers the RNAU process.

4) Mobility state and/or speed of movement of the terminal device.

5) Cell identity when the terminal device enters and/or leaves the first RNA.

The cell identifier may be a 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 the terminal device leaves the first RNA, the network device considers that the stay time of the terminal device in the first RNA has a reference value, and thus the size of the first RNA can be adjusted according to the stay time. When the cell when the terminal device enters the first RNA and the cell when the terminal device leaves the first RNA are close to each other, the network device considers that the stay time of the terminal device in the first RNA has no reference value, so that the size of the first RNA can be temporarily not adjusted.

The network device only needs to know the time information when the terminal device enters and leaves the first RNA, so that the stay time of the terminal device in the first RNA is calculated, or the stay time of the terminal device in the first RNA when the terminal device directly reports the stay time of the terminal device leaving the first RNA is calculated. Thus, optionally, the triggering RNAU procedure described above may be triggered by the terminal device leaving the RNA. Or, it is understood that when the RNAU process is triggered, if the current RNA of the terminal device is not changed, the terminal device does not generate RNA information when the current RNAU process is triggered.

Wherein the terminal device leaving a certain RNA may also be referred to as triggering the RNAU process and the RNA changes.

Steps 402 to 406, which are similar to steps 303 to 307 in the embodiment corresponding to fig. 3, can refer to the foregoing description and are not repeated.

Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA experienced by itself, including the information capable of representing the staying condition of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device may calculate the retention time of the terminal device in the RNA according to the reported timestamp triggering the RNAU process, or the retention time of the terminal device directly reported in the RNA, and then the network device determines whether the retention time of the terminal device is abnormal, and further determines whether the size setting of the RNA is reasonable, for example, if the retention time of the terminal device in a certain RNA is too long, it indicates that the RNA range is possibly too large, and further, the RNA range may be reduced. Conversely, if the terminal device stays in a certain RNA for too short a time, it indicates that the RNA range may be too small, and the RNA range may be increased. Therefore, the proper RNA range is set for the terminal equipment, and the cost of the terminal equipment and the network equipment is reduced.

The main differences between the embodiment corresponding to fig. 4 and the embodiment corresponding to fig. 3 are: in real time corresponding to fig. 3, the terminal device reports the information of the abnormal RNA, and the network device can directly know which RNAs may have problems, thereby adjusting the RNA size. In the embodiment corresponding to fig. 4, the information of the RNA that the terminal device passes through is reported by the terminal device, and the network device needs to determine which RNAs may be abnormal according to the retention condition of the RNA that the terminal device passes through, so as to adjust the size of the RNA.

Fig. 5 is a schematic flow chart of another communication method provided in the embodiment of the present application. This method corresponds to the fifth implementation method of the second information in the embodiment corresponding to fig. 2. This embodiment allows for enhancing an existing MHI, in which the terminal device adds RNA information while recording the MHI.

The method comprises the following steps:

step 501, when the terminal device records the MHI each time, adding RNA information to the MHI, where the RNA information includes RNA information of the first RNA, and specifically includes one or more of the following 1) to 4):

1) identification of the first RNA.

3) And the terminal device records a time stamp (timestamp) of the RNA information, or the current stay time of the terminal device in the first RNA.

The timestamp of the terminal device recording the RNA information can also be understood as the timestamp of the terminal device recording the MHI.

4) A mobility state and/or a movement speed of the terminal device;

the mobility state may be a mobility state of the terminal device at the time of recording the RNA information, or may be an average mobility state of the terminal device in the first RNA. The moving speed may be a moving speed of the terminal device at the time of recording the RNA information, or an average moving speed of the terminal device in the first RNA.

The network device only needs to know the time information when the terminal device enters and leaves the first RNA, so that the stay time of the terminal device in the first RNA is calculated, or the stay time of the terminal device in the first RNA when the terminal device directly reports the stay time of the terminal device leaving the first RNA is calculated. Therefore, optionally, when the terminal device records the MHI, if the current RNA of the terminal device is not changed, the terminal device does not record the RNA information in the MHI. Or it is understood that the terminal device records the RNA information within the MHI at the same time as recording the MHI only when the terminal device leaves the RNA (such as the first RNA described above).

Step 502, the terminal device stops or suspends recording RNA information.

This step is the same as step 303 of the embodiment corresponding to fig. 3, and reference may be made to the foregoing description, which is not repeated.

This step is an optional step.

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

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

The specific implementation manner of this step may refer to the related description of step 307 in the embodiment corresponding to fig. 3, and is not described again.

Based on the above embodiment, the terminal device in the RRC inactive state records the information of the RNA experienced by itself, including the information capable of representing the staying condition of the terminal device in the RNA. After receiving the RNA information reported by the terminal device, the network device may calculate the residence 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 residence time problem, and further determines whether the size of the RNA is reasonable, for example, if the residence time of the terminal device in a certain RNA is too long, it indicates that the RNA range is possibly too large, and further the RNA range may be reduced. Conversely, if the terminal device stays in a certain RNA for too short a time, it indicates that the RNA range may be too small, and the RNA range may be increased. Therefore, the proper RNA range is set for the terminal equipment, and the cost of the terminal equipment and the network equipment is reduced.

The main differences between the embodiment corresponding to fig. 5 and the embodiment corresponding to fig. 4 are: fig. 5 corresponds to an embodiment in which the terminal device carries RNA information in the reported MHI, whereas fig. 4 corresponds to an embodiment in which RNA information is recorded when the RNAU process is triggered, and then one or more recorded RNA information is reported after the reporting time point arrives.
