The communication method 300 of the embodiment of the present application is introduced below through FIG. 5 . The data transmission is in an anonymous way, and the method 300 mainly solves the problem of how to select a terminal device for anonymous transmission.

FIG. 5 shows a schematic flowchart of a communication method 300 provided by an embodiment of the present application. As shown in FIG. 5 , the method 300 includes:

S310, the network device sends the first indication information to the terminal device.

The terminal device receives the first indication information sent by the network device, where the first indication information is used to instruct the terminal device to report the first data.

The first data includes data that needs to be transmitted in an anonymous manner.

Optionally, the first indication information may be carried in a paging message, a system message or other messages.

Optionally, the first data includes MDT data.

Optionally, before the network device sends the first indication information to the terminal device, the method 300 further includes:

The network device determines to collect the first data.

For example, the network device may determine that the first data needs to be collected within a time period or when a certain event is triggered, and then send the first indication information to the terminal device.

For another example, the above-mentioned time period may be when the load of the network device is light at night, and the above-mentioned event trigger may be that the network quality of a certain area suddenly deteriorates.

For another example, the network device may periodically collect the first data, and when the period for collecting the first data is entered, the network device sends the first indication information to the terminal device.

S320, the terminal device determines to establish an anonymous RRC connection with the network device according to the first indication information.

It can be understood that after the terminal determines to establish an RRC connection with the network device, it will perform a process of establishing an anonymous RRC connection. This embodiment of the present application does not limit the process of how to establish an anonymous RRC connection.

Optionally, the first indication information includes user-selected configuration information, and the user-selected configuration information is used by the terminal device to determine whether it is selected, wherein the terminal device determines to establish anonymity with the network device according to the first indication information. RRC connections, including:

The terminal device determines that the terminal device is selected according to the user selection configuration information;

In the case that the terminal device determines that it is selected, it is determined to establish the anonymous RRC connection with the network device.

In this embodiment of the present application, the first indication information indicates that the first data is reported in two ways: implicit indication and explicit indication:

Explicit indication: The first indication information includes two fields, one field is used to indicate the reporting of the first data, and the other field is user selection configuration information, which is used by the terminal device to choose whether to establish an anonymous RRC connection with the network device.

Implicit indication: The first indication information includes a field, which is user selection configuration information. After receiving the first indication information, the terminal device can implicitly learn that the network device wants it to report the first data.

Optionally, it can also be that the first indication information includes a field for instructing to report the first data, but does not include user selection configuration information, then the terminal device determines according to the received first indication information that it needs to communicate with the network device. The anonymous RRC connection is established.

It should be understood that, in this embodiment of the present application, since the first data includes data that needs to be transmitted in an anonymous manner, the user-selected configuration information does not include information for determining a specific terminal device, for example, the identification information of the terminal device, so as to achieve the beneficial effect of anonymity. Effect.

Optionally, the user selection configuration information includes probability information and/or selection conditions.

It can be understood that the user's selection of configuration information may also be called terminal selection of configuration information, or selection of configuration information.

It should be understood that, in this embodiment of the present application, "selected" can be understood as "the terminal device is selected to establish the anonymous RRC connection with the network device", or it can also be understood as "the terminal device is selected to report the first data". Then, "not selected" can be understood as "the terminal device cannot establish the anonymous RRC connection with the network device", or it can also be understood as "the terminal device cannot report the first data".

For example, if the user-selected configuration information includes probability information, then the terminal device determines to establish the anonymous RRC connection with the network device according to the user-selected configuration information, including:

get random value;

When the random value and the probability information satisfy a preset condition, it is determined to establish the anonymous RRC connection with the network device. The preset conditions include but are not limited to:

(1) The ratio of the random value to the maximum random value that can be generated is less than or equal to the probability of being selected;

(2) The ratio of the random value to the maximum random value that can be generated is greater than or equal to the probability of not being selected.

Optionally, the probability information is a ratio, such as a percentage, used to indicate the probability of being selected or not being selected to establish an anonymous RRC connection, and the terminal device determines whether to be selected to establish an anonymous RRC connection by means of a random value.

For example, the probability information indicates that the probability of the terminal device being selected is 40%, the terminal device can randomly generate an integer within 100, if the generated integer is within 40, it is selected; if the generated integer is between 40 and 100, then Not selected.

For another example, the probability information indicates that the probability that the terminal device is not selected is 50%, and the terminal device can randomly generate an integer within 100. If the generated integer is within 50, it will not be selected; if the generated integer is between 50 and 100 is selected.

It should be understood that the probability of being selected and the probability of not being selected in the above example can also be expressed in other forms, for example, the probability of being selected is 0.4 or 2/5, and the probability of not being selected is 0.5 or 1/2.

Optionally, in a possible implementation, the terminal device and the network device may agree in advance that the probability information is the probability of being selected or the probability of not being selected.

It should be understood that, in this embodiment of the present application, the random value may also be generated by the terminal device itself, or may be obtained by the terminal device from other devices, which is not limited in this embodiment of the present application.

It should also be understood that, in this embodiment of the present application, the probability information can be understood as not only a numerical value, but also a threshold. For example, when the random value obtained by the terminal device is greater than or equal to the threshold, the terminal device determines to be Checked.

For example, if the user configuration information includes selection conditions, the selection conditions include location information of the first area, and the terminal device determines to establish the anonymous RRC connection with the network device according to the user selection configuration information, including:

In the case that the terminal device is located in the first area, it is determined to establish the anonymous RRC connection with the network device.

Optionally, the first area may be a geographic area, for example, the location information of the first area may be longitude and latitude information of the first area.

Optionally, the first area may also be a circular area. For example, the location information of the first area may include the location of the center point of the circular area and the radius information of the circle.

Optionally, the selection condition may also include information of a first type, where the first type is a certain type or types of information of the terminal device, and the terminal device determines the connection with the network device according to the user selection configuration information. Establish the anonymous RRC connection, including:

In the case that the terminal device is the first type of terminal device, it is determined to establish the anonymous RRC connection with the network device.

Optionally, the first type of terminal equipment includes but is not limited to one or more of the following types:

(1) Terminal equipment contracted by MDT;

(2) Terminal equipment that is not sensitive to energy;

(3) Terminal equipment of the Internet of Things (IoT);

(4) Terminal equipment that saves some kind of MDT data.

For example, the energy-insensitive terminal device may be a fixed-location terminal device, eg, a terminal device that is always connected to power or is being charged.

For another example, a terminal device that stores certain types of MDT data may be a terminal device that stores a failed MDT log, or a terminal device that stores a periodic MDT log, and so on.

It should be understood that the above only exemplifies a terminal device that is not sensitive to energy and a terminal device that stores certain types of MDT data, and the present application is not limited thereto.

It should also be understood that, in this embodiment of the present application, the terminal device of the first type may be any one of the above types or any combination of the above types.

It should also be understood that any of the probability information, the location information of the first area, and the information of the first type of terminal equipment can also be combined to determine whether the terminal equipment is selected. For example, the probability information and the first type of terminal equipment can be combined. Combined with the location information of the area, the first indication information can indicate that the energy-insensitive terminal device is selected with a probability of 40%. The selection of the terminal device needs to meet two conditions: ① The terminal device is an energy-insensitive terminal device ; ②The random number generated by the terminal device within 100 is within 40.

It should also be understood that the user-selected configuration information in this embodiment of the present application may also be other information, or a combination of other information, probability information, and/or selection conditions, for example, the other information may be the power consumption information of the terminal device, such as , which can be a power consumption threshold. After the terminal device receives the first indication information, it can determine the current power consumption of the terminal device. When the power consumption is less than or equal to the power consumption threshold, the terminal device can be selected. , otherwise it cannot be selected.

In the communication method of the embodiment of the present application, by carrying the user-selected configuration information in the first indication information, it is helpful for the terminal device to determine whether to establish an anonymous RRC connection with the network device. By setting the user-selected configuration information, the network device can select an appropriate terminal The device reports the first data.

In the embodiment of the present application, a timer mechanism may also be used to avoid frequent data transmission by the terminal device, thereby saving power consumption of the terminal device.

Optionally, before the terminal device determines to establish the anonymous RRC connection with the network device according to the first indication information, the method 300 further includes:

The terminal device determines that the first timer is not running, and the state of the first timer can be used by the terminal device to determine whether to establish the anonymous RRC connection with the network device.

For example, if a terminal device has reported MDT data, that is, if a terminal device has established an anonymous RRC connection, the first indication information can be ignored within a certain period of time. For example, the first timer may be started every time it is determined that the establishment of an anonymous RRC connection needs to be initiated, or every time the anonymous RRC connection is released, and during the running of the first timer, if the terminal device receives the first indication information again , the first indication information is ignored. For example, every time when determining whether to initiate the establishment of an anonymous RRC connection or receiving the first indication information, if the first timer is still running, the terminal device ignores the first indication information, otherwise, according to step S320 method to determine if it is selected. Optionally, the first indication information may further include the duration of the first timer. Among them, since the first indication information is ignored within a certain period of time, it can also be understood that if the terminal device receives the first indication information again within a certain period of time, it will no longer execute the corresponding first indication information according to the received first indication information again. operate.

Optionally, after the terminal device determines to establish the anonymous RRC connection with the network device, the method further includes:

The terminal device starts the first timer, and the state of the first timer is used to determine whether to establish an anonymous RRC connection with the network device after the terminal device receives the first indication information next time.

Specifically, the terminal device may start the first timer after establishing the anonymous RRC connection with the network device. It can be judged first whether the first timer has expired. If the first timer has expired, the terminal device can establish an anonymous RRC connection with the network device, otherwise, the anonymous RRC connection with the network device will not be established.

It should be understood that, in the embodiment of the present application, if the first timer is not running, it can also be understood that the first timer has timed out, and that the first timer is running can also be understood that the first timer has not timed out.

It should also be understood that the state of the timer may be "running" or "not running", and one scenario that causes the state of the timer "not running" may be "timeout".

It should also be understood that, in this embodiment of the present application, the moment when the first timer starts may be when the terminal device determines to establish an anonymous RRC connection with the network device, or when the terminal device and the network device have established the anonymous RRC connection. , or when the terminal device starts or ends sending the first data to the network device, or when the terminal device releases the anonymous RRC connection, the present application does not limit the time at which the timer starts.

It should also be understood that the duration of the first timer may be configured by the network device, or may be preset, which is not limited in this embodiment of the present application.

The communication method of the embodiment of the present application, through the timer mechanism, can prevent the terminal device from frequently transmitting data, thereby saving the power consumption of the terminal device.

Optionally, the first indication information may further include delayed establishment configuration information, where the delayed establishment configuration information is used by the terminal device to determine the time point at which the anonymous RRC connection is established.

It should be understood that in the embodiments of the present application, information such as the user selection configuration information, delayed establishment configuration information and other information is included in the first indication information as an example for description, and the user selection configuration information, delayed establishment configuration information and other information may also be different. It is included in the first indication information, but is separately delivered to the terminal device in other information or messages, which is not limited in this embodiment of the present application.

In a possible way, the first indication information sent by the network device may trigger multiple terminal devices to be selected for anonymous RRC connection establishment. If all these terminal devices initiate connection establishment immediately, it will cause a random access process conflict probability. increase, causing a signaling impact on the network. Therefore, a delayed establishment mechanism can be considered. The first indication information may carry delayed establishment configuration information, or the protocol specifies delayed establishment configuration information, for example, delayed establishment configuration information based on a random value or identification information of the terminal device, so that the terminal device can obtain different anonymous RRCs. The time point when the connection is established or the duration of delaying the establishment of the RRC connection enables terminal devices to establish the anonymous RRC connection as scattered as possible.

For example, the delay establishment mechanism may be delay establishment configuration information based on a random value, where the delay establishment configuration information includes a maximum time or time range for delay establishment, or a protocol specifies a maximum time or time range for delay establishment. The terminal device generates a random value, and determines the time point when the anonymous RRC connection is established by the random value.

For example, if the maximum time is 1 minute, the terminal device can generate random numbers within 100, and each random number corresponds to a delay in establishing an anonymous RRC connection.

A possible implementation manner is that the terminal device can obtain a percentage corresponding to the random value through the obtained random value, and 60 seconds*percentage obtains the delay duration. For example, if the random value is 0, it will be initiated immediately, if the random value is 40, the percentage will be 40%, then 60 seconds * 40% = 24 seconds, then the anonymous RRC connection will be established after a delay of 24 seconds.

For another example, if the maximum time is 2 seconds, the terminal device can generate a random number within 100, the terminal device that generates the random value between 0 and 30 can immediately establish an anonymous RRC connection, and the terminal device that generates the random value between 31 and 60 can receive the RRC connection immediately. An anonymous RRC connection is established with a delay of 1 second after the first indication information, and a terminal device generating a random value between 61 and 100 can establish an anonymous RRC connection with a delay of 2 seconds after receiving the first indication information.

For another example, the maximum time is 1 minute, the identification information of the terminal device is the ID of the terminal device, and the terminal device can determine the time point when the corresponding anonymous RRC connection is established according to the value obtained by the remainder function mod(ID, divisor). Among them, divisor can be a preset divisor.

In the communication method of the embodiment of the present application, by carrying the delayed establishment configuration information in the first indication information, in the case that multiple terminal devices need to establish an anonymous RRC connection with the network device, it is helpful to connect multiple terminal devices in different At the time point, the connection is established with the network device, thereby helping to reduce the signaling impact on the network.

Optionally, before the terminal device determines to establish the anonymous RRC connection with the network device, the method 200 further includes:

The terminal device is determined to be in an idle state or an inactive state.

In the NR system, three RRC states are included, namely an idle (idle) state, a connected (connected) state and an inactive (inactive) state. Among them, in the idle state, the terminal device does not establish an RRC connection with the network device, and the terminal device does not save the state of the RRC connection configuration of the air interface; in the connected state, the terminal device and the network device establish an RRC connection state; The terminal device does not establish an RRC connection with the network device, but the terminal device saves the state of the RRC connection configuration of the air interface. For example, for a terminal device in a connected state, an RRC connection with the network device has been established; for a terminal device in an inactive state, it saves the context information of the terminal device.

Optionally, in a possible manner, the above solution is applicable to the terminal device in the idle state, that is, the terminal device in the idle state can determine whether it is selected through the above solution.

Optionally, in another possible manner, the above solution is applicable to an idle or deactivated terminal device, that is, an idle or deactivated terminal device can determine whether it is selected through the above solution.

Optionally, a new RRC state may be introduced to identify the terminal device that has completed the establishment of the anonymous connection, for example, the RRC anonymous state, which is used to indicate the state in which the terminal device and the network device have established an anonymous RRC connection. It can be understood that the RRC anonymous state can also be regarded as a sub-state of the idle state or the inactive state.

For the terminal device that initiates an anonymous RRC connection or the terminal device in the RRC anonymous state, since the network device does not know the identity of the terminal device, it is considered that the terminal device is still in the idle state or inactive state, so when there is downlink data to be sent to the terminal device. , the network device may send a paging message to page the terminal device, optionally, the paging message carries the identification information of the terminal device.

In one embodiment, the terminal device that initiates the establishment of the anonymous RRC connection and enters the RRC anonymous state still monitors the paging message, and determines whether the paging message contains its own identification information to determine whether to be paged. If it is paged, or when the terminal device itself has uplink data to send, for example, the uplink data is not the first data, the terminal device can disconnect the anonymous RRC connection, for example, enter the idle state, and then initiate a normal RRC connection establishment process to enter to the connected state. For example, in the ordinary RRC connection establishment process, the core network obtains the identification information of the terminal device by performing authentication or authentication on the terminal device. The priority of the terminal device for establishing a common RRC connection is higher than the priority of the terminal device for establishing an anonymous RRC connection or performing the first data transmission. Optionally, disconnecting the anonymous RRC connection may include, for example: the terminal device requests the network to release the anonymous RRC connection, or the terminal device notifies the network device that the terminal device will release the RRC connection.

Correspondingly, the network device receives the first data sent by the terminal device.

Here, the terminal device determines that the terminal device is selected, establishes an anonymous RRC connection with the network device, and sends the first data to the network device.

It should be noted that the embodiments of the present application do not limit the manner in which an anonymous RRC connection is established between a terminal device and a network device, that is, any method that can implement anonymity between a terminal device and a network device can implement the embodiments of the present application.

It should be understood that, in this embodiment of the present application, the first indication information may include one of user selection configuration information, delay establishment configuration information, the duration of the first timer (or the information involved in the following), and the like. Or combined, in another possible implementation manner, the user selects the configuration information, delays the establishment of the configuration information, and the information such as the duration of the first timer can be carried in different information and sent to the terminal device at the same time, or, a certain The sequence is delivered to the terminal device respectively, which is not limited in this embodiment of the present application.

In the prior art, if a terminal device needs to be paged to establish an RRC connection, the paging message carries the identification information of the terminal device for paging. In this embodiment of the present application, the network device may not use the identification information of the terminal device for paging, but carry the first indication information in the paging message. After the terminal device receives the first indication information, it may use the first indication The information determines whether an anonymous RRC connection establishment needs to be initiated.

S920, when the condition for active reporting is satisfied, the terminal device determines to establish an anonymous RRC connection with the network device.

For example, the reporting condition included in the first indication information is that the number of failed logs reaches 10. If the terminal device has only 5 failed logs when receiving the first indication information, the terminal device does not yet meet the reporting condition. When the number of failed logs saved by the terminal device reaches 10, the terminal device can actively report the 10 failed logs, and reset the counted number of failed logs to 0. 10, you can choose to actively report.

S930, the terminal device sends the first data to the network device after establishing the anonymous RRC connection with the network device.

In this embodiment of the present application, the difference between method 900 and the user-selected configuration information in the foregoing method 300 is that in method 300, the network device selects a terminal device to report the first data through the user's selection of configuration information, while in method 900, the network device may allow the terminal to report the first data. The device actively reports the first data, and the terminal device can decide whether to report the first data by itself.

It should be understood that after the terminal device determines to establish an RRC connection with the network device, it will perform a process of establishing an anonymous RRC connection.

It should also be understood that the first indication information may include both the user-selected configuration information in the foregoing method 300 and the reporting conditions in the method 900 .

In the communication method of the embodiment of the present application, when the network device needs the terminal device to actively report data that needs to be transmitted in an anonymous manner, the network device can send first indication information to the terminal device, so that the terminal device can actively report the data through an anonymous RRC connection.

In one embodiment, for the scenarios shown in FIG. 8 to FIG. 12 , when the terminal device initiates an anonymous RRC connection, the terminal device may send information to the network device to indicate the triggering scenario of the establishment of the anonymous RRC connection, including: the terminal device actively performs an anonymous RRC connection. transmission, or the terminal device initiates anonymous transmission according to the request of the network device, for example, anonymous transmission based on the first configuration information and the second configuration information.

Optionally, the terminal device may carry in the RRC connection request message or the RRC connection establishment complete message the information that the terminal device initiates anonymous transmission on its own initiative or according to the request of the network device.

The above describes several scenarios in which the terminal device needs to initiate an anonymous RRC connection with reference to FIG. 8 to FIG. 12 . The following describes the security protection mechanism when the terminal device reports the first data with reference to FIG. 13 .

FIG. 13 shows a schematic flowchart of a communication method 1000 according to an embodiment of the present application. As shown in FIG. 13 , the method 1000 includes:

S1010: The network device sends a second message to the terminal device, and the terminal device receives the two messages sent by the network device, where the second message includes first indication information, where the first indication information is used to instruct the terminal device to report the first data.

Optionally, the first data includes data that needs to be transmitted in an anonymous manner.

Optionally, the second message may further include third indication information, where the third indication information includes the first public key. The terminal device uses the first public key to encrypt the first data sent to the network device. Optionally, the first public key is the public key of the network device.

Optionally, the second message is a system message.

Optionally, the system message may be the same system message as the system message in the foregoing method 500, or may be a different system message, which is not limited in this embodiment of the present application.

The method 1000 in this embodiment of the present application mainly relates to an air interface security protection mechanism for anonymous transmission. Considering that the transmission is anonymous and the network device does not know the identity of the terminal device, an asymmetric key mechanism can be used for security protection.

The asymmetric key mechanism requires two keys: a public key and a private key. The public key and the private key are a pair. If the data is encrypted with the public key, only the corresponding private key can be used to decrypt the data; the two parties in the communication exchange public keys. Decrypt the private key.

For anonymous transmission, the public key of the network device can be sent to the terminal device through cell broadcast (for example, a system message), or a security mode command message, etc., and the terminal device uses the public key pair of the network device to send to the network device's public key. The first data is encrypted. After receiving the first data sent by the terminal device, the network device uses the private key corresponding to the public key to decrypt.

S1020, the terminal device determines to establish an anonymous RRC connection with the network device according to the first indication information.

It should be understood that for S1020, reference may be made to the relevant description of the above-mentioned S320, which is not repeated here for brevity.

It should also be understood that after the terminal device determines to establish an RRC connection with the network device, it will perform a process of establishing an anonymous RRC connection. The embodiments of this application do not limit the process of how to establish an anonymous RRC connection. For example, reference may be made to the relevant description of method 200.

S1030, after the terminal device has established the anonymous RRC connection, the network device sends a security mode command message to the terminal device.

The terminal device receives the security mode command message sent by the network device.

It should be understood that the security mode command message is an RRC message, which is used to activate the security of the air interface, and the security mode command message may also have other message names.

It should also be understood that the first public key may also be sent to the terminal device through the security mode command message in S1030. Alternatively, the first public key may also be sent to the terminal device through other messages, and the embodiment of the present application does not limit the sending manner of the first public key.

S1040, the terminal device sends a security mode complete (security mode complete) message to the network device.

Optionally, the security mode completion message carries the second public key of the terminal device, which is used for encryption using the second public key when the network device sends data or signaling to the terminal device.

In this embodiment of the present application, for uplink, the terminal device can use the first public key to encrypt data or signaling, and send the encrypted data to the network device, and the network device can use its own private key for decryption; for downlink, The network device can use the second public key to encrypt data or signaling, and the terminal device can use its own private key to decrypt.

S1050, the terminal device encrypts the first data by using the first public key.

S1060, the terminal device sends the encrypted first data to the network device.

It should be understood that the first data here includes data that needs to be transmitted anonymously, or signaling between the terminal device and the network device.

Optionally, the signaling between the terminal device and the network device includes, but is not limited to, an RRC message carrying anonymous data.

It should be understood that considering the low security requirements of downlink information, no encryption may be considered. If the downlink also needs to be encrypted, the second public key of the terminal device may be sent to the network device in the secure mode completion message.

It should also be understood that, considering that the first data transmitted anonymously is used for the maintenance of the operator's network, the necessity of confidentiality is not strong, so one method is, for the data that needs to be transmitted in an anonymous way, especially for MDT data, The security mechanism of the air interface may not be enabled. For example, the network device may not send the first public key to the terminal device. After the anonymous RRC connection is established, the first data will not be encrypted, and the first data will be directly transmitted, or The network device instructs the terminal device whether to enable the security mechanism of the air interface.

It should also be understood that, in the process of establishing an ordinary RRC connection, the network device will acquire the access capability of the terminal device. In order to better protect the privacy of the terminal device, it is also considered that the amount of data transmitted anonymously is generally relatively small, and there is no need to support mobility, and the terminal device does not need to perform measurement, so it is not necessary to obtain the complete access capability of the terminal device. The access layer capability for anonymous transmission can be a simplified capability, and an independent "terminal device capability for anonymous transmission" can be designed, such as not including measurement capability, not including carrier aggregation capability, including whether to support asymmetric key mechanism, and Supported security algorithms, etc. The simplified terminal device access layer can hide the user's identity to a certain extent. The network device may perform wireless configuration of the terminal device on the air interface based on the "terminal device capability of anonymous transmission".

In a possible implementation manner, the "terminal device capability of anonymous transmission" may be sent by the terminal device to the network device after the terminal device establishes an anonymous RRC connection with the network device. For example, it may be the network device to the terminal. The device sends capability request information, and the terminal device reports "anonymous transmission terminal device capability" to the network device; alternatively, the terminal device can also actively report "anonymous transmission terminal device capability".

In another possible implementation manner, the "terminal device capability of anonymous transmission" may be sent by the terminal device to the network device during the process of establishing an anonymous RRC connection between the terminal device and the network device. The connection establishment completion message carries the "terminal device capability for anonymous transmission".

It should be understood that the air interface security mechanism between the terminal device and the network device, and the terminal device reporting "terminal device capability for anonymous transmission" are also applicable to the above method embodiments.
