Please refer to FIG. 3. FIG. 3 is a schematic flowchart of a radio bearer processing method according to an embodiment of the present application. As shown in the figure, the radio bearer processing method includes the following operations.

Step 301: The network device sends the first information to the first terminal device.

Step 302: The first terminal device receives the first information from the network device.

Step 303: Based on the first information, the first terminal device establishes and/or updates a first relay radio bearer between the first terminal device and the second terminal device.

Wherein, the relay radio bearer between the first terminal device and the network device is the second relay radio bearer. The radio bearer between the remote terminal device and the network device is the first Uu radio bearer. The radio bearer between the second terminal device and the network device is the second Uu radio bearer.

The first information may include at least one of the following: QoS information of the first Uu radio bearer, QoS information of the second Uu radio bearer, QoS information of the first relay radio bearer, the first relay radio bearer and the first Uu The mapping relationship of radio bearers, the mapping relationship between the first relay radio bearer and the second Uu radio bearer, and the mapping relationship between the first relay radio bearer and the first Uu radio bearer and the second Uu radio bearer.

Among them, when the remote terminal device is connected to the network device through the relay terminal device, the relay terminal device is the parent node of the remote terminal device, and the remote terminal device is the child node of the relay terminal device. When a remote terminal device is transformed into a relay terminal device, this parent-child relationship remains unchanged. The parent node of the relay terminal device directly connected to the network device is the network device. All parent-child nodes obtain their own identifiers when establishing a parent-child relationship. When the identity of one of the nodes changes, this node needs to notify all neighboring nodes to update the identity. The direction from the child node to the parent node becomes the upstream direction, otherwise it is the downstream direction.

Optionally, in the case where the second terminal device serves as the remote terminal device and the relay terminal device, the second Uu radio bearer is shown in FIG. Terminal Equipment.

Wherein, when the second terminal device is a remote terminal device and a relay terminal device, the first information received by the first terminal device includes first QoS information and second QoS information.

Wherein, in the case that the second terminal device serves as the remote terminal device and the relay terminal device, the second terminal device receives the second information forwarded by the first terminal device, and the second information received by the second terminal device includes the first QoS information.

Optionally, in the case where the second terminal device is used as the remote terminal device, the second Uu radio bearer is shown in FIG. 6, and as shown in the figure, the establishment of the second Uu radio bearer needs to pass through the first terminal device.

Wherein, when the second terminal device is a remote terminal device, the first information received by the first terminal device includes the second QoS information.

It can be seen that in the embodiment of the present application, when the second terminal device is a different type of terminal device, the first information received by the first terminal device is different, which is beneficial to improve the first terminal device in the establishment of the first terminal device.

Example 1

In an implementation manner of the present application, the second terminal device serves as a relay terminal device, and the first relay between the first terminal device and the second terminal device is established or updated based on the first information Radio bearer, including:

Determining, by the first terminal device, a first mapping relationship between the first relay radio bearer and the first Uu radio bearer based on the first QoS information;

Determining, by the first terminal device, the third QoS information that the first relay radio bearer needs to satisfy based on the first mapping relationship and the first QoS information;

The first terminal device establishes or updates the first relay radio bearer based on the third QoS information.

Wherein, the first QoS information is used to indicate requirements for the radio bearer of the first relay (for example, delay requirements, packet loss rate requirements, priority requirements, etc.). The first QoS information has different requirements for the first relay radio bearer, and the first mapping relationship between the first relay radio bearer and the first Uu radio bearer is different.

Optionally, the first terminal device and the second terminal device have established N relay radio bearers, the N relay radio bearers have a one-to-one correspondence with N pieces of QoS information, and the N is a positive integer; The first terminal device determining the first mapping relationship between the first relay radio bearer and the first Uu radio bearer based on the first QoS information includes:

The first terminal device determines a target relay radio bearer based on the first QoS information and the N QoS information, the N relay radio bearers include the target relay radio bearer, and the target relay radio bearer The QoS information corresponding to the bearer and the first QoS information satisfy a preset rule;

The first terminal device establishes or updates a first mapping relationship between the target relay radio bearer and the first Uu radio bearer.

The preset rule includes at least one of the following: the delay included in the QoS information corresponding to the target relay radio bearer is closest to the delay included in the first QoS information; and the QoS corresponding to the target relay radio bearer The maximum data transmission rate included in the information is closest to the maximum data transmission rate included in the first QoS information; the minimum data transmission rate included in the QoS information corresponding to the target relay radio bearer is the same as the minimum data transmission rate included in the first QoS information. The data transmission rate is the closest; the priority included in the QoS information corresponding to the target relay radio bearer is the closest to the priority included in the first QoS information.

Further, the first terminal device determining the third QoS information that the first relay radio bearer needs to meet based on the first mapping relationship and the first QoS information includes:

If the QoS information corresponding to the target relay radio bearer is better than the first QoS information, the first terminal device determines the QoS information corresponding to the target relay radio bearer as the third QoS information;

If the first QoS information is better than the QoS information corresponding to the target relay radio bearer, the first terminal device determines the first QoS information as the third QoS information.

It should be noted that the delay included in the QoS information corresponding to the target relay radio bearer is greater than the delay included in the first QoS information; and/or the maximum data included in the QoS information corresponding to the target relay radio bearer The transmission rate is greater than the maximum data transmission rate included in the first QoS information; and/or the minimum data transmission rate included in the QoS information corresponding to the target relay radio bearer is greater than the minimum data transmission rate included in the first QoS information; And/or the priority included in the QoS information corresponding to the target relay radio bearer is greater than the priority included in the first QoS information.

Further, that the first terminal device updates the first relay radio bearer based on the third QoS information includes:

If the third QoS information is QoS information corresponding to the target relay radio bearer, the first terminal device maintains the QoS information corresponding to the target relay radio bearer;

If the third QoS information is the first QoS information, and the first QoS information and the QoS information corresponding to the target relay radio bearer satisfy a second preset rule, the first terminal device is based on The first QoS information updates the QoS information corresponding to the target relay radio bearer.

It should be noted that since the first QoS information is a standardized QoS parameter in the Uu protocol, and the QoS information corresponding to the relay radio bearer is a standardized QoS parameter in the PC5 protocol, the first QoS information needs to be converted to PC5 through a preset algorithm. The standardized QoS parameters in the protocol are then adjusted based on the converted first QoS information corresponding to the QoS information of the target relay radio bearer. The preset algorithm is an existing algorithm and will not be described here.

In addition, after re-establishing a relay radio bearer between the first terminal device and the second terminal device based on the third QoS information, the first terminal device needs to establish a mapping between the newly established relay radio bearer and the first Uu radio bearer Relationship, so that the first terminal device can quickly determine the newly established relay radio bearer when forwarding the data packet. In addition, the establishment of a relay radio bearer based on QoS information is an existing technology, and it will not be described here.

For example, assuming that the first QoS information includes delay, there are three relay radio bearers between the first terminal device and the second terminal device, such as relay radio bearer 1, relay radio bearer 2, and relay radio bearer 3. If the first QoS information includes a delay of 1s, the QoS information corresponding to relay radio bearer 1 includes a delay of 5s, and the QoS information corresponding to relay radio bearer 2 includes a delay of 8s, and relay radio bearer 3 corresponds to The delay included in the QoS information is 1.5s. It can be seen that the delay of the relay radio bearer 3 is closest to the delay included in the first QoS information, so the determined first mapping relationship is the mapping relationship between the relay radio bearer 3 and the first Uu radio bearer. The delay included in a QoS information is better than the delay included in the QoS corresponding to the relay radio bearer 3. Therefore, the determined third QoS information is the first QoS information, and finally the first terminal device can update the relay radio based on the third QoS information. Bearer 3 can also establish a new relay radio bearer between the first terminal device and the second terminal device based on the third QoS information.

It can be seen that in this embodiment of the application, the QoS information of the relay radio bearer to be established or updated is determined according to the QoS information of the Uu radio bearer to be established, and then the relay radio bearer is established or updated according to the QoS information, which is beneficial to Ensure the reliability of data transmitted by the relay wireless bearer.

Example 2

In an implementation manner of the present application, the second terminal device serves as a relay terminal device and a remote terminal device, a first relay radio bearer A and a first relay radio bearer B, and the first information is based on the Establishing or updating the first relay radio bearer between the first terminal device and the second terminal device includes:

The first terminal device determines the second mapping relationship between the first relay radio bearer A and the first Uu radio bearer based on the first QoS information and the second QoS information, and determines all The third mapping relationship between the first relay radio bearer B and the second Uu radio bearer;

The first terminal device determines the fourth QoS information that the first relay radio bearer A needs to satisfy based on the second mapping relationship and the first QoS information, and based on the third mapping relationship and the first QoS information, 2. The QoS information determines the fifth QoS information that the first relay radio bearer B needs to meet;

The first terminal device establishes or updates the first relay radio bearer A based on the fourth QoS information, and establishes or updates the first relay radio bearer B based on the fifth QoS information.

Optionally, the first terminal device determines a second mapping relationship between the first relay radio bearer A and the first Uu radio bearer based on the first QoS information and the second QoS information , And determining the third mapping relationship between the first relay radio bearer B and the second Uu radio bearer includes:

If the first QoS information and the second QoS information include different types of information, the first terminal device determines the second mapping relationship based on the first QoS information, and determines the second mapping relationship based on the second QoS information The third mapping relationship.

Among them, assuming that the first QoS information only includes time delay, and the second QoS information only includes priority, the first QoS information and the second QoS information include different types of information; it is also assumed that the first QoS information only includes time delay, and the second QoS information only includes time delay. If the QoS information only includes the packet loss rate, the first QoS information and the second QoS information include different types of information; it is also assumed that the first QoS information includes delay and packet loss rate, and the second QoS information includes only the delay. The first QoS information and the second QoS information include different types of information, and so on.

It should be noted that the method for determining the second mapping relationship and the third mapping relationship is the same as the method for determining the first mapping relationship. For details, refer to the method for determining the first mapping relationship described above, which will not be described here. The determination method of the fourth QoS information and the fifth QoS information is the same as the determination method of the third QoS information. For details, refer to the determination method of the third QoS information described above, which will not be described here. The specific implementation of establishing or updating the first relay radio bearer A based on the fourth QoS information is the same as the specific implementation of establishing or updating the first relay radio bearer based on the third QoS information. For details, refer to the third QoS information described above. The specific implementation manner of establishing or updating the first relay radio bearer will not be described here. The specific implementation of establishing or updating the first relay radio bearer B based on the fifth QoS information is the same as the specific implementation of establishing or updating the first relay radio bearer based on the third QoS information. For details, refer to the third QoS information described above. The specific implementation manner of establishing or updating the first relay radio bearer will not be described here.

For example, suppose that the first QoS information includes delay and the second QoS information includes priority. Therefore, two relay radio bearers are required to meet the first QoS information and the second QoS information, respectively, the first terminal device and the second terminal There are three relay radio bearers between devices, such as relay radio bearer 1, relay radio bearer 2, and relay radio bearer 3. If the delay included in the first QoS information is 1s, the priority included in the second QoS information is 3, the priority of the QoS information corresponding to the relay radio bearer 1 is 2, and the delay of the QoS information corresponding to the relay radio bearer 2 It is 8s, and the delay of the QoS information corresponding to the relay radio bearer 3 is 1.5s. It can be seen that the delay of the relay radio bearer 3 is the closest to the delay included in the first QoS information, and the priority of the relay radio bearer 1 is the closest to the priority included in the second QoS information. Therefore, the determined second mapping relationship is The mapping relationship between the relay radio bearer 3 and the first Uu radio bearer, the determined third mapping relationship is the mapping relationship between the relay radio bearer 1 and the second Uu radio bearer, and then due to the timing included in the first QoS information The delay is better than the delay included in the QoS corresponding to the relay radio bearer 3, and the priority included in the second QoS information is better than the priority included in the QoS corresponding to the relay radio bearer 1, so the determined fourth QoS information is the first QoS Information, the fifth QoS information is the second QoS information. Finally, the first terminal device can update the relay radio bearer 3 based on the fourth QoS information, or it can establish a new relationship between the first terminal device and the second terminal device based on the fourth QoS information. The first terminal device can update the relay radio bearer 1 based on the fifth QoS information, and can also establish a new relay radio bearer between the first terminal device and the second terminal device based on the fifth QoS information. Carrying 2.

It can be seen that in this embodiment of the application, the establishment or update of two relay radio bearers is determined according to the QoS information of the first Uu radio bearer and the QoS information of the second Uu radio bearer, and the two relay radio bearers established or updated are established or updated. It can meet different QoS information requirements and help ensure the reliability of data transmitted by the relay radio bearer.

Example 3

In an implementation manner of the present application, the second terminal device serves as a relay terminal device and a remote terminal device, and the relationship between the first terminal device and the second terminal device is established or updated based on the first information. The first relay radio bearer includes:

The first terminal device determines, based on the first QoS information and the second QoS information, the first relay radio bearer and the second Uu radio bearer, and the first relay radio bearer and the second Uu radio bearer. The fourth mapping relationship between the first Uu radio bearers;

Determining, by the first terminal device, the sixth QoS information that the first relay radio bearer needs to satisfy based on the fourth mapping relationship, the first QoS information, and the second QoS information;

The first terminal device establishes or updates the first relay radio bearer based on the sixth QoS information.

Optionally, the first terminal device determines the first relay radio bearer and the second Uu radio bearer, and the first relay based on the first QoS information and the second QoS information The fourth mapping relationship between the radio bearer and the first Uu radio bearer includes:

If the information types included in the first QoS information and the second QoS information are the same, the first terminal device determines the fourth mapping relationship based on the first QoS information and the second QoS information.

Among them, assuming that the first QoS information only includes time delay, and the second QoS information only includes time delay, the first QoS information and the second QoS information include the same type of information; it is also assumed that the first QoS information only includes time delay, and the second QoS information includes only time delay. If the QoS information only includes the packet loss rate, the first QoS information and the second QoS information include different types of information; it is also assumed that the first QoS information includes delay and packet loss rate, and the second QoS information includes only the delay. The first QoS information and the second QoS information include different types of information, and so on.

It should be noted that the method for determining the fourth mapping relationship is the same as the method for determining the first mapping relationship. For details, refer to the method for determining the first mapping relationship described above, which will not be described here. The determination method of the sixth QoS information is the same as the determination method of the third QoS information. For details, refer to the determination method of the third QoS information described above, which will not be described here. The specific implementation manner of establishing or updating the first relay radio bearer based on the sixth QoS information is the same as the specific implementation manner of establishing or updating the first relay radio bearer based on the third QoS information. Or update the specific implementation of the first relay radio bearer, which will not be described here.

For example, assuming that the first QoS information includes delay and the second QoS information includes delay, it is determined to update or establish a relay radio bearer. There are 3 relay radio bearers between the first terminal device and the second terminal device. Articles, such as relay radio bearer 1, relay radio bearer 2, and relay radio bearer 3. If the delay included in the first QoS information is 1s, the delay included in the second QoS information is 1.5s, the delay of the QoS information corresponding to the relay radio bearer 1 is 5s, and the delay of the QoS information corresponding to the relay radio bearer 2 is 5s. The delay is 8s, and the delay of the QoS information corresponding to the relay radio bearer 3 is 1.5s. It can be seen that the delay of the relay radio bearer 3 is the closest to the delay included in the first QoS information, and the delay of the relay radio bearer 3 is the closest to the delay included in the second QoS information. The mapping relationship between the first Uu radio bearers and between the relay radio bearer 3 and the second Uu radio bearer is the fourth mapping relationship, and then the delay included in the first QoS information is better than the QoS corresponding to the relay radio bearer 3 The delay included in the second QoS information is equal to the delay included in the QoS corresponding to the relay radio bearer 3. Therefore, the determined delay of the sixth QoS information is 1, and finally the first terminal device can be based on the sixth QoS.

Example 5

In an implementation manner of the present application, when the second terminal device is used as a relay terminal device, the first information includes eighth QoS information of the first relay radio bearer, and the first A sixth mapping relationship between the relay radio bearer and the third Uu radio bearer, where the third Uu radio bearer is a radio bearer between the remote terminal device and the network device.

Among them, the eighth QoS information is used to indicate the requirements for the radio bearer of the first relay (for example, delay requirements, packet loss rate requirements, priority requirements, etc.). The eighth QoS information has different requirements for the first relay radio bearer, and the sixth mapping relationship between the first relay radio bearer and the third Uu radio bearer is different.

The second terminal device receives the second information forwarded by the first terminal device, and the second information received by the second terminal device and the first information received by the first terminal device may be the same or different. The second information is used for the first information. The second terminal device establishes or updates the relay radio bearer between the second terminal device and the remote terminal device.

For example, assuming that the eighth QoS information includes delay, there are three relay radio bearers between the first terminal device and the second terminal device, such as relay radio bearer 1, relay radio bearer 2, and relay radio bearer 3. If it is determined through the sixth mapping relationship that the first radio bearer is the relay radio bearer 3, the delay of the relay radio bearer 3 is 1.5s, and the delay included in the eighth QoS information is 1s. Since the delay included in the eighth QoS information is 1s, the delay of the relay radio bearer 3 is 1.5s.

For details, refer to the specific implementation manner of establishing or updating the first relay radio bearer based on the eighth QoS information and the sixth mapping relationship described above, which will not be described here.

For example, assuming that the ninth QoS information includes delay and the tenth QoS information includes priority, there are three relay radio bearers between the first terminal device and the second terminal device, such as relay radio bearer 1, relay Radio bearer 2 and relay radio bearer 3. If it is determined through the seventh mapping relationship that the first radio bearer C is the relay radio bearer 3, and the first radio bearer D is determined to be the relay radio bearer 2 through the eighth mapping relationship, the delay of the relay radio bearer 3 is 1.5s, and After the priority of radio bearer 2 is 3, the delay included in the ninth QoS information is 1s, and the priority included in the tenth QoS information is 2. Since the delay included in the ninth QoS information is 1s, the delay included in the relay radio bearer 3 is 1.5s, the priority included in the tenth QoS information is 2, and the priority included in the relay radio bearer 2 is 3. It can be seen that the delay of the ninth QoS information is better than the delay of the relay radio bearer 3, and the priority of the relay radio bearer 2 is better than the tenth QoS information, so the relay radio bearer 3 is updated based on the ninth QoS information, The relay radio bearer 2 is maintained.

For example, assuming that the ninth QoS information includes delay and the tenth QoS information includes priority, there are three relay radio bearers between the first terminal device and the second terminal device, such as relay radio bearer 1, relay Radio bearer 2 and relay radio bearer 3. If it is determined through the seventh mapping relationship that the first radio bearer C is the relay radio bearer 3, the delay of the relay radio bearer 3 is 1.5s, and the delay included in the ninth QoS information is 1s, the first radio bearer is determined by the eighth mapping relationship. There is no first radio bearer D for the relay radio bearer between the terminal device and the second terminal device. Since the delay included in the ninth QoS information is 1s and the delay of the relay radio bearer 3 is 1.5s, the first radio bearer D does not exist. It can be seen that the delay of the ninth QoS information is better than the delay of the relay radio bearer 3. Therefore, the relay radio bearer 3 is updated based on the ninth QoS information, and the first radio bearer D is established based on the tenth QoS information.

It can be seen that in the embodiment of the present application, the two Uu radio bearers are respectively mapped to the relay radio bearers with different QoS information, which is beneficial to improve the reliability of data transmission.
