Detailed ways

In the prior art, the auxiliary information can be sent to the terminal only after the terminal enters the connected state, and the base station does not configure any resource for sending the positioning measurement result to the terminal in advance. This will bring more message overhead and positioning delay, so it is necessary to consider how to optimize this process to reduce the message overhead and positioning delay.

The inventor of the present invention found through research that in the prior art, since the base station does not know how long it will take for the terminal to complete the positioning measurement, the base station cannot configure resources for the terminal in advance for the terminal to send the measurement result, so that the terminal can only After entering the connected mode, the positioning measurement result is sent after acquiring the uplink time-frequency resources.

Referring to FIG. 1, FIG. 1 is a flowchart of a first positioning method in an embodiment of the present invention. The first positioning method may be used for a terminal, and may further include steps S11 to S12:

Step S11: the terminal receives a paging message sent by the base station, where the paging message carries positioning indication information;

Step S12: According to the positioning indication information, the terminal sends positioning execution information to the base station, where the positioning execution information is used for terminal positioning.

It can be understood that, in a specific implementation, the method can be implemented in the form of a software program, and the software program runs in a processor integrated inside a chip or a chip module.

In the specific implementation of step S11, the base station may send a paging (Paging) message to the terminal, and the positioning indication information may also be configured by the base station to indicate positioning.

The paging message may carry early data transmission (mobile terminal-early data transmission, MT-EDT) indication information and positioning indication information initiated by the network.

In the specific implementation of step S12, the terminal may send the positioning execution information or positioning capability to the base station; when the positioning execution information is the indication information of the positioning method, the base station may determine the required positioning measurement duration according to the positioning method.

In step S22, the terminal 22 sends the indication information of the positioning method to the base station 21.

Specifically, the indication information of the positioning method is used to indicate the positioning method, wherein the positioning method includes the following positioning methods: enhanced cell ID positioning (enhanced cell ID, E-CID), time difference of arrival positioning (Time Difference of Arrival, TDOA) , Observed Time Difference of Arrival (OTDOA), etc.; wherein, the indication information of the positioning method can be, for example, the identification (ID), serial number, index code (Index) of the positioning method, etc., or other suitable Indicative information for determining the positioning method.

Further, the positioning execution information may be sent through a radio resource control RRC message or a MAC CE.

The RRC message is the third RRC message of the RACH process or the RACH process message A, and may be selected from the group consisting of: RRCConnectionSetupRequest message, RRCEarlyDataRequest message, and RRCConnectionResumeRequest message.

In the embodiment of the present invention, by using the spare bits in the RRC message to carry the positioning execution information, no additional overhead is required, which is beneficial to saving communication resources.

The third RRC message or message A in the RACH process is sent in the Lth (L is defined as a positive integer such as 1, 2, 3, etc.) MAC SDU.

In the first specific implementation, a new MAC CE can be introduced to carry the positioning execution information.

Specifically, to introduce a new MAC CE, one can be selected from the reserved LCIDs (such as "01111") to indicate the MAC CE that sends the positioning execution information.

Wherein, specific optional fields may be selected from field R, field F, field E, field F2, and the like.

In a non-limiting example, it can be multiplexed with the power headroom reporting LCID, that is, the LCID used to indicate that the MAC CE that sends the positioning execution information is "11010". At this time, the fields R and F of the subheader can be used at the same time. , Field E, Field F2, etc.

Taking field R as an example, the previous value of field R has always been 0. Now, 1 can be used to indicate positioning execution information, and 0 can be used to indicate power headroom reporting.

In the embodiment of the present invention, the positioning execution information is sent through an appropriate RRC message or MAC CE message, and the existing message flow can be used to realize the sending of the positioning execution information, thereby reducing the complexity of the flow, reducing the message overhead and reducing the positioning delay.

Continuing to refer to FIG. 2, after step S22, the base station 21 may determine the required positioning measurement duration.

Specifically, in a possible implementation manner, the base station 21 may determine a positioning method according to the indication information, and determine the positioning measurement duration required for adopting the positioning method.
