FIG. 2 shows a method and a schematic interaction diagram of wireless communication according to an embodiment of the present invention from the perspective of device interaction, the method comprising:

S210, the second terminal device determines first indication information, where the first indication information includes at least one type of indication information: RRC connection status indication information used to indicate a radio resource control RRC connection status between the second terminal device and the base station, Location relationship indication information indicating a positional relationship between the second terminal device and the base station, RAT indication information for indicating a radio access technology RAT used between the second terminal device and the first terminal device, a communication connection state indication information indicating a communication connection state between the second terminal device and the first terminal device, and a policy indication for indicating whether the first terminal device receives a paging message sent by the base station for the second terminal device Information, wherein the location relationship includes: the second terminal device is within the coverage of the base station or the second terminal device is outside the coverage of the base station;

S220. The second terminal device sends the first indication information to the first terminal device.

S230. The first terminal device determines, according to the first indication information, whether to receive the paging message.

Therefore, when the base station sends the paging message, the first terminal device performs the paging message. Receiving processing, that is, receiving the paging message or not receiving the paging message, and further forwarding the paging message to the second terminal device.

By way of example and not limitation, the first terminal device is any one of a plurality of first terminal devices, and the second terminal device may be any one of a plurality of second terminal devices capable of establishing a connection with the first terminal device. The embodiment of the present invention will be described in detail by taking the terminal device #A (that is, an example of the first terminal device) and the terminal device #B (that is, an example of the second terminal device) as an example.

Alternatively, the terminal device #A may be a Relay UE, and the terminal device #B may be a WD.

It should be understood that the communication connection status is used to indicate whether there is a communication link between the terminal device #A and the terminal device #B. By way of example and not limitation, the communication link may be established based on the RAT, or may be based on NFC. For the terminal device #A, the paging message for the terminal device #B can be received only when the communication link exists, and the paging message is forwarded to the terminal device #B.

It should also be understood that, as an example and not by way of limitation, the connection state between the terminal device #B and the base station may not be limited to the RRC connection state, or may be the terminal device #B established by other means and the upper layer of the base station, for the terminal device. Invisible connection status for #A.

Meanwhile, it should be noted that, in the embodiment of the present invention, the paging message for the terminal device #B includes any one of the following: a first paging message for indicating the terminal device #B, for indicating the system. a second paging message with a message change, a third paging message for indicating an Earthquake and Tsunami Warning System (ETWS) notification, and a commercial mobile alert system (Commercial Mobile Alert System, The fourth paging message notified by the abbreviation "CMAS".

It should also be understood that before the terminal device #A forwards the paging message to the terminal device #B, the terminal device #B needs to set its own user identification information (for example, the device ID, International Mobile Subscriber Identification Number, The "IMSI") and the Serving-Temporary Mobile Subscriber Identity (S-TMSI) are sent to the terminal device #A for determining whether there is a paging message for the terminal device #B. .

Alternatively, the terminal device #B transmits the user identification information to the terminal device #A when establishing a communication connection with the terminal device #A.

In summary, if the terminal device #A determines that the paging message needs to be received, the terminal device #A receives the paging message when the base station detects the paging message, and the terminal device #A receives the paging message and checks the paging. Whether the message includes the user identification information of the terminal device #B, or the system message change information, or the ETWS notification information, or the CMAS notification information. If the at least one type of information is included, the terminal device #A forwards the paging message to the terminal. Device #B.

It should be noted that, although the embodiment of the present invention is directed to the terminal device #A, in the actual method implementation, regarding the paging message sent by the base station for the terminal device #B, the terminal device #B and the terminal device #A are in motion. It can be echoed. That is, if the terminal device #A receives the paging message, the terminal device #B receives the paging message forwarded by the terminal device #A; if the terminal device #A does not receive the paging message, the terminal device #B receives the transmission from the base station. The paging message. This can be a system default setting or a mode negotiated by terminal device #A and terminal device #B.

Therefore, in the method of wireless communication according to the embodiment of the present invention, the first terminal device determines whether to receive the paging message for the second terminal device sent by the base station according to the first indication information, and implements receiving processing for the paging message to avoid In the prior art, the first terminal device needs to continuously listen and receive the paging message, thereby wasting power consumption, and can effectively save power consumption of the first terminal device, and at the same time, increase system flexibility.

In S210, the terminal device #B determines the instruction information #1 (that is, an example of the first instruction information), and the instruction information #1 includes the instruction information #1A (that is, an example of the RRC connection state indication information) and the instruction information #1B ( That is, an example of the positional relationship instruction information, the instruction information #1C (that is, an example of the RAT instruction information), the instruction information #1D (that is, an example of the communication connection state instruction information), and the instruction information #1E (that is, the policy indication information) At least one of the indications in the example.

Specifically, in the application scenario of the present invention, a communication connection needs to be established between the terminal device #B and the terminal device #A, so that communication between the terminal device #B and the terminal device #A can be performed. For different types of indication information, the terminal The device #B determines the indication information #1 in a different manner, that is, directly determines the indication information #1 (ie, mode 1), and indirectly determines the indication information #1 (ie, mode 2).

Mode 1

When the indication information #1 includes only at least one of the indication information #1A, the indication information #1B, the indication information #1C, or the indication information #1D, the terminal device #B can directly determine the indication information #1.

Mode 2

When the indication information #1 includes the indication information #1E, the policy indication information is optionally the second terminal device according to the RRC connection status indication information, the location relationship indication information, the RAT indication information, or the communication connection status. At least one of the indication information is determined by the information. That is, The indication information #1E is determined by the terminal device #B based on at least one of the indication information #1A, the instruction information #1B, the instruction information #1C, or the instruction information #1D. Therefore, it should be understood that the terminal device #B determines the instruction information #1E based on the above four kinds of indication information (ie, whether the terminal device #A receives the paging message transmitted between the terminals) and the terminal device in step S230. #A is similar to the process and method for determining the result based on the above four kinds of indication information. In order to avoid redundancy, the specific determination process and method will be described in detail later.

When the terminal device #B determines the instruction information #1, the terminal device #B transmits the instruction information #1 to the terminal device #A in S220, and further, the terminal device #A receives the instruction information #1.

Specifically, as described above, a communication connection needs to be established between the terminal device #A and the terminal device #B, and the communication connection causes a communication link between the terminal device #A and the terminal device #B, and the communication link may be Based on Bluetooth, WLAN, D2D, infrared, NFC and other RATs. Therefore, after the communication link is successfully established between the terminal device #A and the terminal device #B, the terminal device #B transmits the instruction information #1 to the terminal device #A based on the communication link between the two. Further, in S230, the terminal device #A determines whether or not to receive the paging message for the terminal device #B transmitted by the base station based on the instruction information #1, and performs subsequent reception processing for the paging message.

It should be noted that the manner in which the terminal device #A obtains the indication information #1 is not limited to the indication information sent by the terminal device #B, and the terminal device #A may also obtain the indication information #1 by other means or manner. For example, in some prior art, the base station needs to obtain the indication information #1 from the terminal device #B, so that the terminal device #A can obtain the indication information #1 from the base station; similarly, it can also be from the mobility management entity (Mobility Management). Entity, referred to as "MME"), obtains the indication information #1; further, when the terminal device #A establishes a data radio bearer ("Data Center" ("DRB") for the terminal device #B, the terminal device #A is equivalent to the indirect It is known that the RRC connection state of the terminal device #B is in the connected state, which is also the manner in which the indication information #1 is acquired. By way of example and not limitation, any manner or means by which terminal device #A obtains indication information #1 is within the scope of the present invention.

It should be noted that, for the indication information #1C, the terminal device #A may not need the terminal device #B to send the indication information #1C, and after the terminal device #A and the terminal device #B establish the communication connection, the terminal device #A is connected according to the communication. In the state, it is possible to determine the RAT between the terminal device #A and the terminal device #B by itself.

Optionally, after determining the manner of receiving the paging message, the terminal device #A may send the third indication information to the terminal device #B, where the information #3 (ie, one of the third indication information) Example) is used to indicate whether the terminal device #A receives the paging message. Thus, as a whole in a communication system, the terminal device #B can determine how it needs to receive the paging message according to the indication information #3, that is, the paging message sent by the receiving base station or the forwarding by the receiving terminal device #A The paging message. Thus, in this way, the terminal device #B can open a suitable receiver according to the result determined by the indication information #3, for example, if the paging message transmitted by the base station is received by the terminal device #B, the terminal device #B turns on the cellular reception. If the terminal device #A receives the paging message and forwards it to the terminal device #B, the terminal device #B needs to open the receiver according to the communication connection between itself and the terminal device #A. Further, if the terminal device #B and the terminal device #A are connected by Bluetooth, the terminal device #B is turned on by the Bluetooth receiver; if the terminal device #B and the terminal device #A are connected through the WLAN, then The terminal device #B is turned on by the WLAN receiver.

In S230, the indication information #1 includes at least one of the five types of indication information, that is, whether the paging message can be received according to any one of the indication information, or the at least one indication information may be integrated to determine whether to receive the paging message. In this way, while saving the power consumption of the terminal device #A, the flexibility of the system is also increased.

For the embodiment of the present invention, optionally, the first indication information includes policy indication information for indicating whether the first terminal device receives a paging message sent by the base station for the second terminal device, where the policy indication information is The second terminal device determines the at least one indication information according to the RRC connection status indication information, the location relationship indication information, the RAT indication information, or the communication connection status indication information.

As described above, the terminal device #B determines whether the terminal device #A determined based on the indication information #1A, the instruction information #1B, the indication information #1C, the instruction information #1D receives the paging message (ie, the instruction information #1E indicates The process and method are similar to the process and method for the terminal device #A based on the above four kinds of indication information for the result of the paging message, except that the difference is only in the execution subject, and the terminal determined based on the above four kinds of indication information For the result of the paging message, the device #A may be the terminal device #A, and the execution body may also be the terminal device #B. Herein, in order to avoid redundancy, the process and method for determining based on the above four types of indication information are described with terminal device #A as the execution subject, and the process and method for determining the terminal device #B are not described in detail herein. Refer to the description below.

First, when the four types of indication information exist alone, the terminal device #A determines whether to receive the paging message, and corresponds to four cases (ie, case 1, case 2, case 3, case 4); When there are multiple types of indication information, the terminal device #A determines whether to receive a paging message. The process can correspond to 4 cases (ie, case 5, case 6, case 7, case 8), and at the same time, a detailed description of the special cases that may occur in the last 4 cases.

Situation 1

The indication information #1 has only the indication information #1A, that is,

Optionally, when the first indication information includes the RRC connection status indication information, and the first terminal device determines, according to the first indication information, whether to receive the paging message, the method includes:

If the RRC connection status indication information indicates that the RRC connection status is an RRC connected state, the first terminal device determines not to receive the paging message; or

If the RRC connection status indication information indicates that the RRC connection status is an RRC idle state, the first terminal device determines to receive the paging message.

Further, when the RRC connection status of the terminal device #B changes, for example, before a certain time, the RRC connection status of the terminal device #B is in the RRC connected state, and the terminal device #A does not receive the paging message; After a moment, the RRC connection state of the terminal device #B is the RRC idle state, the terminal device #A no longer does not receive the paging message, and the terminal device #A needs to change from the state in which the paging message is not received to start receiving the paging message. The status of the message.

Situation 2

The indication information #1 has only the indication information #1B, that is,

Optionally, when the first indication information includes the location relationship indication information, the first terminal device determines, according to the first indication information, whether to receive the paging message, including:

If the location relationship indication information indicates that the location relationship is that the second terminal device is within the coverage of the base station, the first terminal device determines not to receive the paging message; or

If the location relationship indication information indicates that the location relationship is that the second terminal device is outside the coverage of the base station, the first terminal device determines to receive the paging message.

Further, when the location relationship of the terminal device #B changes, for example, before a certain time, the terminal device #B is within the coverage of the base station, and the terminal device #A does not receive the paging message; after a certain time The terminal device #B is outside the coverage of the base station, and the terminal device #A no longer does not receive the paging message, and the terminal device #A needs to change from the state in which the paging message is not received to the state in which the paging message is started to be received.

It should be noted that, in the case that the terminal device #B is in the coverage of the base station, although the terminal device #A does not receive the paging message, as described above, in the actual method implementation process, the terminal device #B needs to receive directly. The paging message, however, if the terminal device #B is far from the base station, It can be considered that the terminal device #B is in the edge zone within the coverage of the base station, that is, the extended coverage area. For the terminal device #B, if the paging message sent by the base station is received, the paging message may not be received. At the same time, the power consumption of the terminal device #B is also wasted. Therefore, in order to ensure that the terminal device #B can receive the paging message, the terminal device #A can receive the paging message, so that the terminal device #B receives the terminal. The paging message forwarded by device #A.

In the implementation of the actual method, if it is necessary to consider a relatively detailed positional relationship, when the terminal device #A acquires the positional relationship, the location level may be set for the location relationship. For example, the first level indicates that the terminal device #B is outside the coverage of the base station. The second level indicates that the terminal device #B is in the range of the base station and is far away from the base station, and the third level indicates that the terminal device #B is in the coverage of the base station and is closer to the base station. When the location level is the third level, the terminal device# A does not receive the paging message, that is, the terminal device #B directly receives the paging message. When the location level is the first level or the second level, the terminal device #A receives the paging message, that is, the terminal device #B receives the terminal. The paging message forwarded by device #A. In this way, compared with the prior art, the terminal device #B can effectively receive the paging message without increasing the power consumption of the terminal device #A, thereby improving system flexibility.

For the above two cases, optionally, when the terminal device #A determines to receive the paging message, the RAT used between the terminal device #A and the terminal device #B may be preset for any one of the first communication technology sets. The first communication technology. Communication technology #1 (an example of the first communication technology) belongs to a communication technology with low power consumption, for example, short-distance communication technologies such as Bluetooth, WLAN, and infrared. In this way, the power consumption of the terminal device #A can be further reduced, and at the same time, the power consumption of the terminal device #B can be effectively reduced.

Situation 3

The indication information #1 has only the indication information #1C, that is,

Optionally, when the first indication information includes the RAT indication information, the first terminal device determines, according to the first indication information, whether to receive the paging message, including:

If the RAT indication information indicates that the RAT belongs to the first communication technology set, the first terminal device determines to receive the paging message, the first communication technology set includes at least one predefined first communication technology; or

If the RAT indication information indicates that the RAT belongs to the second communication technology set, the first terminal device determines not to receive the paging message, and the second communication technology set includes at least one predefined second communication technology, the first The communication technology is different from the second communication technology.

As described above, the communication technology set #1 (an example of the first communication set) includes at least one predefined communication technology #1, and the communication technology set #2 (an example of the second communication set) includes at least one pre- The defined communication technology #2, optionally, the predefined communication technology #1 may be a short-distance communication technology such as Bluetooth, WLAN, infrared, etc. The predefined communication technology #2 may be a cellular technology such as D2D, LTE Sidelink, 5G Sidelink, etc. . By way of example and not limitation, any communication technology that satisfies the above conditions is within the scope of the invention.

Further, when the RAT between the terminal device #A and the terminal device #B changes, for example, before a certain time, the RAT between the terminal device #A and the terminal device #B is the communication technology #1, the terminal device #A The paging message needs to be received; after a certain time, the RAT between the terminal device #A and the terminal device #B is the communication technology #2, the terminal device #A no longer receives the paging message, and the terminal device #A needs to receive the message. The status of the paging message translates to a state in which the reception of the paging message is stopped.

It should be noted that, since the terminal device #A and the terminal device #B can directly learn the communication technology between themselves and the other party when establishing the connection, the terminal device #B can be sent to the terminal device #A to indicate the terminal. The indication information of the RAT used between the device #A and the terminal device #B, and thus, the terminal device #A can directly determine whether to receive the paging message according to the indication information #1C.

It should be noted that, when the terminal device #A determines to receive the paging message according to the indication information #1C, since the terminal device #A and the terminal device #B use the low-power communication technology #1, compared with the present In any technology, no matter which communication technology is used between the two, it is also effective to save the power consumption of the terminal device #A. Of course, the terminal device #A determines not to receive the paging message, and further saves the power consumption of the terminal device #A.

It should be understood that, for the above three cases, if it is determined by the terminal device #A according to the indication information #1 whether to receive the paging message, as described above, the terminal device #A may be used to indicate whether the terminal device receives the paging message. The indication information #3 is sent to the terminal device #B, so that the terminal device #B can know the manner of receiving the paging message according to the indication information #3, thereby opening the corresponding receiver without opening an unnecessary receiver. The system power consumption can be further saved; if it is determined by the terminal device #B according to the indication information #1 whether the terminal device #A receives the paging message, thereby indicating whether the terminal device #A receives the paging message or not 1E is sent to the terminal device #A, so that the terminal device #A knows whether it needs to receive the paging message. Since both the terminal device #A and the terminal device #B know their own receiving manner for the paging message, they can open each other. Corresponding receiver; if both terminal device #B and terminal device #A directly determine the result according to the indication information #1, it is not necessary for the two to send each other for indication. Whether the client device receives the paging message #A indication information (e.g., case 3), thereby opening the respective corresponding receiver, the system can save the power consumption.

For example, if the terminal device #B receives the paging message sent by the base station, the terminal device #B opens the cellular receiver; if the terminal device #A receives the paging message and forwards the message to the terminal device #B, the terminal Device #B needs to open the receiver according to the communication connection between itself and terminal device #A. Further, if the terminal device #B and the terminal device #A are connected by Bluetooth, the terminal device #B is turned on by the Bluetooth receiver; if the terminal device #B and the terminal device #A are connected through the WLAN, then The terminal device #B is turned on by the WLAN receiver.

It should also be understood that the above three cases exist on the premise that there is a communication connection between the terminal device #A and the terminal device #B.

Optionally, when the terminal device #A determines not to receive the paging message, the communication link between the terminal device #A and the terminal device #B may be released, thereby saving power, and the terminal device #B receives the transmission sent by the base station. After the paging message, a communication link with the terminal device #A is established, and the next reception result is judged.

Situation 4

The indication information #1 has only the indication information #1D, that is,

When the first indication information includes the communication connection status indication information, the first terminal device determines, according to the first indication information, whether to receive the paging message, including:

If the communication connection status indication information indicates that the communication connection status is that the communication link between the second terminal device and the first terminal device is disconnected, the first terminal device determines not to receive the paging message.

It should be noted that the disconnection of the communication link may be a state in which the connection between the terminal device #A and the terminal device #B has been disconnected, or the connection between the terminal device #A and the terminal device #B may be disconnected immediately. status. Specifically, determining that the communication connection state is a state in which the communication link is disconnected may be determined in two ways:

Mode A

The communication link between the terminal device #A and the terminal device #B is directly disconnected, and the terminal device #A can indirectly know that the connection between the two is disconnected, so that the paging message is not received.

Mode B

The terminal device #B is about to switch from the state connected to the terminal device #A to the state connected to the other terminal device, that is, the terminal device #B will no longer maintain a communication connection with the terminal device #A, and the terminal device #B will notify in advance. The terminal device #A itself needs to switch the terminal device, so that the terminal device #A will not receive the paging message after receiving the notification message, or the terminal device #B according to the handover. The message of the terminal device itself determines whether the terminal device #A receives the paging message, and then transmits the indication information #1E to the terminal device #A.

The first four cases described above are that multiple types of indication information exist separately, and further determining whether the terminal device #A receives the paging message, but the present invention is not limited thereto, and various types of indication information may also be used in combination. Next, when a plurality of types of indication information are simultaneously present, the terminal device #A determines whether or not to receive the paging message.

It should be noted that when the indication information #1 includes multiple types of indication information including the indication information #1D, the communication connection state is prioritized, and the priority of the communication connection state may be set during the actual method implementation. The priority is set to the highest level, and the terminal device #A does not receive the paging message as long as there is a disconnection of the communication link. As mentioned above, the first three cases are considered in the presence of a communication link.

Therefore, in the case where it is determined that there is a communication link between the terminal device #A and the terminal device #B, detailed analysis and description will be made below for the case where the other types of indication information included in the instruction information #1 correspond.

Situation 5

The indication information #1 includes the indication information #1A and the indication information #1B, that is, the first indication information includes the RRC connection status indication information and the location relationship indication information.

During the implementation of the actual method, we can set different priorities for different situations according to actual needs.

When the indication information #1 includes the above two types of indication information, if we are concerned with the location relationship between the terminal device #B and the base station, setting the priority indicating that the location relationship is higher than indicating the RRC connection state, that is, the terminal device #A determines whether the result of receiving the paging message is the same as case 2;

If we are concerned with the RRC connection status of the terminal device #B and the base station, setting the priority indicating that the RRC connection state is higher than the priority indicating the location relationship, that is, the terminal device #A determines whether to receive the paging message. The result is the same as case 1.

Certainly, in the implementation of the actual method, if the step-by-step determination can be made, the priority indicating that the RRC connection state is higher than the priority indicating the location relationship is set, and the determining step is as follows: first determining whether the terminal device #B is in the RRC connected state or In the RRC idle state, if it is in the RRC connected state, it is determined not to receive the paging message; if it is in the RRC idle state, the next determination is made. That is, if the terminal device #B is in the idle state and the terminal device #B is in the coverage of the base station, the terminal device #A may determine to receive the paging message, and may also determine not to receive the paging message, preferably, the terminal Device #A determines not to receive the paging message; if terminal device #B is in an idle state, and terminal device #B When the coverage of the base station is outside, the terminal device #A determines that the paging message needs to be received. The advantage of this step-by-step judgment is that when the terminal device #B is in the RRC connected state, the problem that the terminal device #A also needs to receive the paging message is avoided, which not only effectively saves the power consumption of the terminal device #A, but also It also increases the flexibility of the system.

Situation 6

The indication information #1 includes the indication information #1A and the indication information #1C, that is, the first indication information includes the RRC connection status indication information and the communication connection status indication information.

In the same way, during the implementation of the actual method, we can set different priorities for different situations according to actual needs.

When the indication information #1 includes the above two types of indication information, if we are concerned with the RAT used between the terminal device #A and the terminal device #B, the setting indicates that the RAT has a higher priority than the RRC connection state. That is, the terminal device #A determines whether the result of receiving the paging message is the same as case 3;

Certainly, in the actual method implementation process, if the RRC connection status is set to be higher than the priority indicating the RAT, the step of determining the receiving policy #A is as follows: first determining that the terminal device #B is in The RRC connected state is also an RRC idle state. If it is in the RRC connected state, the terminal device #A determines not to receive the paging message; if it is in the RRC idle state, it performs the next determination. That is, if the terminal device #B is in the idle state, and the RAT belongs to the communication technology set #1, the terminal device #A determines to receive the paging message; if the terminal device #B is in the idle state, and the RAT belongs to the communication technology set# 2. Terminal device #A determines not to receive the paging message. Similarly, the advantage of this stepwise judgment is that when the terminal device #B is in the RRC connected state, the problem that the terminal device #A also needs to receive the paging message is avoided, which not only effectively saves the power consumption of the terminal device #A. At the same time, it also increases the flexibility of the system.

Situation 7

If we are concerned with the location relationship between the terminal device #B and the base station, the setting indicates that the location is off. The priority of the system is higher than the priority indicating the RAT, that is, the terminal device #A determines whether the result of receiving the paging message is the same as the case 2;

If we are concerned with the RAT used between the terminal device #A and the terminal device #B, the setting indicates that the priority of the RAT is higher than the priority indicating the location relationship, that is, the terminal device #A determines whether to receive the paging message. The result is the same as in case 3.

Certainly, in the actual method implementation process, if the RAT can be determined step by step, the priority indicating that the RAT is higher than the priority indicating the location relationship is determined, and the step of determining the receiving policy #A is as follows: first determining that the RAT belongs to the communication technology set. #1 belongs to the communication technology set #2. If the RAT belongs to the communication technology set #1, the terminal device #A determines to receive the paging message regardless of whether the terminal device #B is within the coverage of the base station or the coverage of the base station; If the RAT belongs to the communication technology set #2, it is determined whether the terminal device #B is within the coverage of the base station or the coverage of the base station: if the terminal device #B is within the coverage of the base station, the terminal device #A determines not to receive the search. If the terminal device #B is outside the coverage of the base station, the terminal device #A determines to receive the paging message.

That is, the final result is: if the RAT belongs to the communication technology set #1, whether the terminal device #B is within the coverage of the base station or the coverage of the base station, the terminal device #A determines to receive the paging message; if the RAT A communication technology set #2, and the terminal device #B is within the coverage of the base station, the terminal device #A determines not to receive the paging message; if the RAT belongs to the communication technology set #2, and the terminal device #B is at the base station Outside the coverage, terminal device #A determines to receive the paging message. Similarly, the advantage of this stepwise judgment is that the terminal device #B outside the coverage of the base station can also receive the paging message, which not only effectively saves the power consumption of the terminal device #A, but also improves the system. Flexibility.

Situation 8

The indication information #1 includes the indication information #1A, the indication information #1B, and the indication information #1C, that is, the first indication information includes the RRC connection status indication information, the location relationship indication information, and the communication connection status indication information.

When the indication information #1 includes the above three types of indication information, if we are concerned with the RRC connection status of the terminal device #B and the base station, setting the priority indicating that the RRC connection status is the highest, that is, the terminal device #A determines Whether the result of receiving the paging message is the same as case 1;

If we are concerned with the RAT used between the terminal device #A and the terminal device #B, the setting is indicated. The priority of the RAT is the highest, that is, the terminal device #A determines whether the result of receiving the paging message is the same as the case 3;

If we are concerned with the location relationship between the terminal device #B and the base station, the priority indicating that the location relationship is set to be the highest, that is, the terminal device #A determines whether the result of receiving the paging message is the same as the case 2.

Certainly, in the implementation of the actual method, if it can be determined step by step, setting a priority indicating that the RRC connection state is higher than a priority indicating the RAT, and setting a priority indicating that the RAT is higher than a priority indicating the location relationship, The determining step is as follows: first determining whether the terminal device #B is in the RRC connected state or the RRC idle state; if it is in the RRC connected state, the terminal device #A determines not to receive the paging message; if the terminal device #B is in the RRC idle state, proceeding to the next step It is determined whether the RAT belongs to the communication technology set #1 or belongs to the communication technology set #2. If the RAT belongs to the communication technology set #1, the terminal device #A determines to receive the paging message regardless of whether the terminal device #B is within the coverage of the base station or the coverage of the base station; if the RAT belongs to the communication technology set #2, Determining whether the terminal device #B is within the coverage of the base station or outside the coverage of the base station: if the terminal device #B is within the coverage of the base station, the terminal device #A determines not to receive the paging message; if the terminal device #B is in the base station Outside the coverage, terminal device #A determines to receive the paging message.

That is, the final determined result is: if the terminal device #B is in the idle state, and the RAT belongs to the communication technology set #1, the terminal device #A determines whether the terminal device #B is within the coverage of the base station or the coverage of the base station. Receiving the paging message; if the terminal device #B is in the idle state, and the RAT belongs to the communication technology set #2, and the terminal device #B is within the coverage of the base station, the terminal device #A determines not to receive the paging message; When the terminal device #B is in the idle state, and the RAT belongs to the communication technology set #2, and the terminal device #B is outside the coverage of the base station, the terminal device #A determines to receive the paging message. By the same token, the advantage of this stepwise judgment is that not only the power consumption of the terminal device #A is effectively saved, but also the flexibility of the system is improved.

It should be understood that the manner or method of using the various types of indication information listed above is only an exemplary description, and the present invention is not limited thereto, and the type of the combined indication information may be arbitrarily changed according to actual application conditions.

In some implementations of the prior art, the base station or the MME needs to know the manner in which the terminal device #A or the terminal device #B receives the paging message,

Optionally, the first terminal device sends the second indication information to the base station, where the second indication information is used to indicate whether the first terminal device receives the paging message.

Specifically, the terminal device #A transmits the indication information #2 (an example of the second indication information) to the base station, so that the base station or the MME can learn (the base station forwards the reception policy #A to the MME) the terminal device #A and the terminal device. #B For receiving the paging message sent by the base station, the base station or the MME may perform paging to the terminal device #A and the terminal device #B by using the correct paging mode. For example, the base station learns that the terminal device #A receives the paging message, and the base station directly pages the terminal device #A; the base station learns that the terminal device #B receives the paging message, and the base station directly pages the terminal device #B.

It should be understood that the indication information #2 and the indication information #1E are substantially the same, and are used to indicate whether the terminal device #A receives the paging message, except that the object to be transmitted and received is different.

The above describes that the terminal device #A determines, according to the indication information #1, whether the terminal device #A receives the paging message for the terminal device #B transmitted by the base station, and for the terminal device #B, according to the indication. The information #1 determines its own receiving mode (i.e., receives a paging message sent by the base station or receives a paging message forwarded by the terminal device #A).

It should be understood that the manner in which the terminal device #B receives the paging message depends on the manner in which the terminal device #A receives the paging message, or, as described above, the paging message for the terminal device #B transmitted by the base station, the terminal device# B and terminal device #A may be in response to the action. That is, if the terminal device #A receives the paging message, the terminal device #B receives the paging message forwarded by the terminal device #A; if the terminal device #A does not receive the paging message, the terminal device #B receives the transmission from the base station. The paging message. That is, the terminal device #B needs to determine a target device in order to correctly receive the paging message by itself.

Next, the process and method of determining the target device by the terminal device #B will be described in detail.

Optionally, the second terminal device determines, from the first terminal device and the base station, a target device corresponding to the first indication information;

The second terminal device receives the paging message from the target device. That is, in the terminal device #A indeed When determining whether to receive the paging message, the terminal device #B needs to determine the target device from the base station and the terminal device #A, and the target device has a correspondence relationship with the first indication information, so that the terminal device #B correctly receives the paging message.

Similarly, the process and method for determining the target device by the terminal device #B is similar to the process and method for the terminal device #A to determine whether to receive the paging message. There are also eight cases. To avoid cumbersome, a brief description will be made here.

Situation 1

The indication information #1 has only the indication information #1A, that is,

Optionally, when the first indication information includes the RRC connection status indication information, the second terminal device determines, from the first terminal device and the base station, a target device corresponding to the first indication information, including:

If the RRC connection status indication information indicates that the RRC connection status is an RRC connected state, the second terminal device determines the base station as the target device; or

If the RRC connection status indication information indicates that the RRC connection status is the RRC idle state, the second terminal device determines the first terminal device as the target device.

It should be noted that, if the RRC connection state is the RRC connected state, the terminal device #B receives the paging message sent by the base station, and the paging message belongs to the second paging message and the third paging message used for the foregoing. And any one of the fourth paging messages does not include the first paging message.

Situation 2

The indication information #1 has only the indication information #1B, that is,

Optionally, when the first indication information includes the location relationship indication information, the second terminal device determines, from the first terminal device and the base station, a target device corresponding to the first indication information, including:

If the location relationship indication information indicates that the location relationship is that the second terminal device is within the coverage of the base station, the second terminal device determines the base station as the target device; or

If the location relationship indication information indicates that the location relationship is that the second terminal device is outside the coverage of the base station, the second terminal device determines the first terminal device as the target device.

It should be noted that, in the case that the terminal device #B is in the coverage of the base station, although the terminal device #B uses the base station as the target device, that is, receives the paging message sent by the base station, if the terminal device #B is far away from the base station, It can be considered that the terminal device #B is in the edge zone within the coverage of the base station, that is, the extended coverage area. For the terminal device #B, if the paging message sent by the base station is received, the paging message may not be received. In the case, at the same time, the power consumption of the terminal device #B is also wasted. Therefore, in order to ensure that the terminal device #B can receive the paging message, the terminal device #A can receive the paging message, so that the terminal device #B receives The paging message forwarded by the terminal device #A determines the terminal device #A as the target device.

Similarly, in the actual implementation of the method, if it is necessary to consider a relatively detailed positional relationship, a positional level can be set for the positional relationship. The setting of the priority is the same as above. When the location level is the third level, the terminal device #B determines the base station as the target device, and when the location level is the first level or the second level, the terminal device #B determines the terminal device #A. For the target device. In this way, compared with the prior art, the terminal device #B can effectively receive the paging message without increasing the power consumption of the terminal device #A, thereby improving system flexibility.

Situation 3

The indication information #1 has only the indication information #1C, that is,

If the RAT indication information indicates that the RAT belongs to the first communication technology set, the second terminal device determines the first terminal device as the target device, and the first communication technology set includes at least one predefined first communication technology ;or

If the RAT indication information indicates that the RAT belongs to the second communication technology set, the second terminal device determines the base station as the target device, and the second communication technology set includes at least one predefined second communication technology, where The first communication technology is different from the second communication technology.

As described above, the communication technology set #1 (an example of the first communication set) includes at least one predefined communication technology #1, and the communication technology set #2 (an example of the second communication set) includes at least one predefined communication Technology #2, optionally, the predefined communication technology #1 may be a short-range communication technology such as Bluetooth, WLAN, infrared, etc. The predefined communication technology #2 may be D2D, LTE Sidelink, 5G Cellular technology such as Sidelink. By way of example and not limitation, any communication technology that satisfies the above conditions is within the scope of the invention.

It should be understood that the above three cases exist on the premise that there is a communication connection between the terminal device #A and the terminal device #B.

Optionally, when the terminal device #B determines the base station as the target device, the communication link between the terminal device #A and the terminal device #B may be released, thereby saving power, and the terminal device #B receives the homing sent by the base station. After the message is called, a communication link with the terminal device #A is established.

It should also be noted that when the communication link between the terminal device #A and the terminal device #B belongs to the communication technology set #1, the terminal device #B receives the paging message transmitted by the terminal device #A, due to the communication technology collection #1 The communication technology #1 used has less power consumption, and for the terminal device #B, it is more power-saving than the paging message sent by the receiving base station. Since most terminal devices #B are small in size and weight, the battery requirements to be used are small and light, and thus the power supply is limited. In practical applications, the user requires the terminal device #B to have a long standby time. Therefore, in the existing communication system, the terminal device #B is often required to have an extremely low power consumption level.

Therefore, in the embodiment of the present invention, the second terminal device determines, according to the RAT indication information, a suitable communication technology used between the second terminal device and the first terminal device, which can effectively reduce power consumption of the second terminal device. The second terminal device is particularly important.

Situation 4

The indication information #1 has only the indication information #1D, that is,

Optionally, when the first indication information includes the communication connection status indication information, the second terminal device determines, from the first terminal device and the base station, a target device corresponding to the first indication information, including:

And if the communication connection status indication information indicates that the communication connection status is that the communication link between the second terminal device and the first terminal device is disconnected, the second terminal device determines the base station as the target device.

The first four cases mentioned above are cases where multiple types of indication information exist separately, thereby determining the target device in which the terminal device #B receives the paging message, but the present invention is not limited thereto, and various types of indication information may also be used in combination. Next, a method in which the terminal device #B determines the target device when a plurality of types of indication information exist simultaneously will be considered.

Situation 5

The indication information #1 includes the indication information #1A and the indication information #1B, that is, the first indication information includes the The RRC connection status indication information and the location relationship indication information.

When the indication information #1 includes the above two types of indication information, if we are concerned with the location relationship between the terminal device #B and the base station, setting the priority indicating that the location relationship is higher than indicating the RRC connection state, that is, the terminal device #Bdetermine the result of the target device as in case 2;

If we are concerned with the RRC connection state of the terminal device #B and the base station, setting the priority indicating that the RRC connection state is higher than the priority indicating the location relationship, that is, the terminal device #B determines the result of the target device as in the case 1 .

Certainly, in the implementation of the actual method, if it can be determined step by step, the priority indicating that the RRC connection state is higher than the priority indicating the location relationship is set, and the step of specifically determining the target device is determined by the terminal device #A to determine whether to receive the The step of paging the message, no more cumbersome description here.

Situation 6

When the indication information #1 includes the above two types of indication information, if we are concerned with the RAT used between the terminal device #A and the terminal device #B, the setting indicates that the RAT has a higher priority than the RRC connection state. That is, the terminal device #B determines the result of the target device as in the case 3;

Certainly, in the implementation of the actual method, if it can be determined step by step, the priority indicating that the RRC connection state is higher than the priority indicating the RAT is set, and the step of specifically determining the target device is determined by the terminal device #A to determine whether to receive the homing The step of calling the message, no more cumbersome description here.

Situation 7

Similarly, during the implementation of the actual method, we can set different situations according to actual needs. Different priorities.

If we are concerned with the location relationship between the terminal device #B and the base station, the priority indicating that the location relationship is higher than the priority indicating the RAT, that is, the result of the terminal device #B determining the target device is the same as the case 2;
