measurement, MDT, AI task, positioning, storage.

Step 404, the network device performs terminal association.

When the second terminal is in an idle state, the first terminal triggers the second terminal to initiate an RRC (Radio Resource Control ) connection and terminal association procedure. When the second terminal is in a connection state, the first terminal or the second terminal triggers a terminal association process.

In this process, the network device allocates a second terminal identifier and/or an association identifier to the second terminal, and sends the second terminal identifier and/or the association identifier to the first terminal or the second terminal.

step 602, the network device establishes RRC connection with the second terminal, and allocates a second terminal identifier and/or an association identifier to the second terminal, so as to instruct the second terminal to complete terminal association. The association identifier is an identifier which is reassigned by the network equipment for the first terminal and the second terminal and is used for indicating 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 completion message to the network device.

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

In the embodiment of the present application, in 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, where the request is used to request the network device to associate the first terminal with the second terminal. And then, the network equipment distributes a second terminal identifier and/or an associated identifier for the second terminal and sends the second terminal identifier and/or the associated identifier to the first terminal, and correspondingly, the first terminal acquires the second terminal identifier and/or the associated identifier.

In practical application, in the current positioning process, considering that the NB-IoT (Narrow Band Internet of Things ) terminal is limited in capability, positioning measurement cannot be well supported in a connected state, and accordingly, accurate positioning estimation cannot be obtained, so that the NB-IoT terminal is required to enter an idle state to perform positioning measurement. In the NB-IoT positioning scenario, in combination with the above embodiments, positioning measurements may be performed with a normal terminal. Specifically, in the above embodiment, the first terminal may be an NB-IoT UE 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 task offload request message, and returns the positioning result to the NB-IoT UE (first terminal).

The minimization of drive test is one of the important means for evaluating the network quality of the mobile communication operator, can reflect specific network conditions, and provides important basis for developing network optimization (such as coverage optimization, mobility management optimization, capacity optimization, qoS (Quality of Service, quality of service) parameter optimization and the like). In order to solve the problem that the idle state MDT occupies the terminal memory, in the embodiment of the application, the first terminal stores data to be stored into the second terminal with larger storage space, and reports the measurement result to the network device when the second terminal enters the connection state. In order to solve the problem of high power consumption of the terminal, in the embodiment of the application, the first terminal with the power saving requirement unloads the MDT task to the second terminal, so that the first terminal is prevented from consuming excessive power. Wherein the interaction procedure of the first terminal and the second terminal may refer to the procedure described in the above embodiments.

In the above embodiment, by offloading the task of the terminal to other peripheral trusted terminals, the influence on the power consumption, storage and the like of the current terminal is reduced, uplink coverage can be improved, throughput is improved, and multi-terminal capability coordination is realized.
