- the network side device provides configuration parameters for two or more relay operations, and selects the medium to be used according to the service information of the remote terminal. Following the operation.
- the terminal when the terminal needs to perform service transmission, it can first determine whether the first condition information for relay operation is satisfied. For example, if the RSRP between the terminal and the serving cell is lower than a certain threshold, it means that the terminal is at the edge of the cell and can pass other information. The user conducts transit transmission; if the L2 and L3 architectures have different condition restrictions, and when the terminal only meets one of the conditions at this time, it can only initiate a relay operation that meets the conditions for transmission. When both conditions are met, a relay operation can be selected according to the service information, where the selection condition can be configured on the network side, or pre-defined, or implemented by the terminal's own algorithm.
- Example 1 When a terminal initiates a specific service, it can select a corresponding relay operation.

- a specific identifier such as a service ID or a QoS ID, which belongs to a list supported by a certain relay operation
- Example 3 When the service initiated by the terminal has certain characteristics, for example, IP packets can use L3 relay operations, and non-IP (non-IP) packets can use L2 relay operations.
- IP packets can use L3 relay operations
- non-IP (non-IP) packets can use L2 relay operations.
- Example 4 When the terminal initiates the service, the block error rate is required to be higher, for example, lower than 10 ⁇ -6. At this time, to avoid packet loss caused by handover, L2 relay operation can be adopted.
- Example 5 When the service initiated by the terminal has high QoS requirements, such as high priority or service continuity requirements, at this time, to avoid packet loss caused by handover, L2 relay operation can be adopted.
- QoS requirements such as high priority or service continuity requirements
- Example 6 when the service initiated by the terminal has a short duration, for example, after a small number of data packets are sent, the link is torn down immediately, and the L3 relay operation can be used at this time.
- Example 7 when the terminal that initiates the service, there is a certain binding ⁇ attribution ⁇ collaboration ⁇ access restriction ⁇ cost sharing relationship with the relay terminal, for example, between the mobile phone and wearable device of the same user, or remote The terminal and the relay terminal move together in the same vehicle, and the L3 relay operation can be used at this time.
