In step 403, the first terminal sends its terminal identifier (such as C-RNTI) and terminal association indication to the second terminal through the task offloading request through the sidelink interface. In addition, the first terminal may also carry a list of tasks to be offloaded . As shown in Figure 6, the first terminal triggers the second terminal to initiate an RRC connection and the terminal association process may include:

Step 601, the second terminal initiates an RRC connection establishment request to the network device, the request carries the terminal identifier of the first terminal, and may also carry an RRC connection establishment cause value (such as a cause value indicating to assist other terminals to complete tasks);

Step 602, the network device establishes an RRC connection with the second terminal, assigns a second terminal identifier and/or an association identifier to the second terminal, and instructs the second terminal to complete terminal association. The association identifier is an identifier redistributed by the network device for the first terminal and the second terminal, and is used to indicate the association relationship between the first terminal and the second terminal.

Step 603, when the RRC connection establishment is completed, the second terminal sends an RRC connection establishment complete message to the network device.

Afterwards, in step 405, the second terminal notifies the first terminal of the second terminal identifier and/or the terminal association identifier through a task offloading confirmation message, and the message may also carry a list of supported offloading tasks.

In the embodiment of the present application, in the above step 404, the first terminal may also trigger the network device to associate the first terminal with the second terminal. Specifically, the first terminal may send a request to the network device, for requesting the network device to associate the first terminal with the second terminal. Then, the network device assigns the second terminal identifier and/or the association identifier to the second terminal, and sends it to the first terminal, and correspondingly, the first terminal obtains the second terminal identifier and/or the association identifier.

In practical applications, in the current positioning process, considering the limited capabilities of Narrow Band Internet of Things (NB-IoT) terminals, it cannot support positioning measurement well in the connected state, and correspondingly cannot obtain more accurate positioning. Therefore, it is required that the NB-IoT terminal needs to enter the idle (English can be expressed as idle) state to perform positioning measurement. In the NB-IoT positioning scenario, in combination with the above embodiments, normal terminals can be used to perform positioning measurement. Specifically, in the above embodiments, the first terminal may be an NB-IoT user equipment (expressed as UE in English), and the second terminal may be a normal terminal. The NB-IoT UE (first terminal) requests the normal terminal (second terminal) to perform positioning measurement for it through the second task offload request message, and returns the positioning result to the NB-IoT UE (first terminal).

Minimizing the drive test is one of the important means for mobile communication operators to evaluate the network quality. It can reflect the specific network conditions and provide network optimization (such as coverage optimization, mobility management optimization, capacity optimization, Quality of Service (QoS) Parameter optimization, etc.) provides an important basis for the development. In order to solve the problem that the MDT in the idle state occupies the terminal memory, in the embodiment of this application, the first terminal stores the data to be stored in the second terminal with a larger storage space, and reports the measurement results to the network when the second terminal enters the connected state equipment. In order to solve the problem of high terminal power consumption, in the embodiment of the present application, the first terminal that needs to save power offloads the MDT task to the second terminal, thereby preventing the first terminal from consuming too much power. Wherein, the interaction process between the first terminal and the second terminal may refer to the process described in the above embodiments.

In the above embodiments, by offloading the tasks of the terminal to other nearby trusted terminals, the impact on power consumption and storage of the current terminal is reduced, uplink coverage can be improved, throughput can be improved, and multi-terminal capability coordination is realized.
