DETAILED DESCRIPTION

Reference will now be made in detail to examples of the present disclosure, which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of examples do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.

In the related art, industry insiders have proposed that mobile cellular networks may provide services for unmanned aerial vehicles. However, there is no effective solution for what kind of service to provide and how to provide the service.

The inventor of the present disclosure found that the basis of providing services is that a base station needs to know the flight path information of an unmanned aerial vehicle, so that the base station can better plan a home cell for the unmanned aerial vehicle according to the flight path, which provides a reference for selecting a target cell. The base station may also provide other services for an unmanned aerial vehicle based on the flight path information, which are not listed here. Therefore, how to obtain the flight path information of an unmanned aerial vehicle is an urgent problem to be solved.

In order to solve the above-mentioned problems, in the present example, during the handover process, a source base station sends flight path information to a target base station, to increase an information source for the target base station to obtain flight path information, thereby facilitating the target base station to obtain the flight path of an unmanned aerial vehicle, and better providing services for the unmanned aerial vehicle.

FIG. 1 is a flow chart showing a method for transmitting flight information according to an example of the present disclosure. The method for transmitting flight information is used in access network equipment such as a base station. As illustrated in FIG. 1, the method includes the following operations at block 101-102.

At block 101, handover request related signaling is generated, the handover request related signaling carrying flight path related information of an unmanned aerial vehicle.

At block 102, the handover request related signaling is sent to a target base station.

In the present example, during the handover process, flight path related information may be sent from a source base station to a target base station, so that the target base station better plans a cell for an unmanned aerial vehicle and other user equipment according to flight path related information, or provides other services for the unmanned aerial vehicle. The target base station may obtain the flight path related information more timely. For example, the flight path related information includes the number of flight path points, flight path point information, etc.

The target base station may receive and parse the handover request related signaling to obtain the flight path related information. The target base station may obtain the flight path related information from the source base station, and the source base station is used as an information source for obtaining the flight path related information, so that the target base station may obtain the flight path related information in time.

In one example, the handover request related signaling includes first handover request signaling; and

the operation at block 102 includes step A.

In the step A, the first handover request signaling is sent to a target base station through an X2 interface (an interface between two base stations).

In the present example, if the source base station and the target base station have X2 interfaces, the first handover request signaling can be transmitted through the X2 interface. The present example improves the first handover request signaling, so that the first handover request signaling can carry flight path related information, and transmission of the flight path related information during the handover process is realized.

In one example, an RRC context information element in the first handover request signaling carries flight path related information of an unmanned aerial vehicle.

The present example uses the RRC context information element (IE) in the first handover request signaling to carry the flight path related information, which provides a feasible solution for carrying the flight path related information.

In one example, the handover preparation information signaling in the RRC context information element carries flight path related information of an unmanned aerial vehicle.

The present example further improves the RRC context information element, uses the handover preparation information signaling therein to carry flight path related information, which provides a feasible solution for carrying the flight path related information.

In one example, access stratum context signaling in the handover preparation information signaling carries flight path related information of an unmanned aerial vehicle.

The present example further improves the handover preparation information signaling, uses the access stratum context (AS-context) signaling therein to carry flight path related information, which provides a feasible solution for carrying the flight path related information.

An example of the access stratum context signaling is shown as follows:

In one example, the handover request related signaling includes handover required signaling; and

the operation at block 102 includes step B.

In step B, the handover required signaling is sent to an MME through an S1 interface (an interface between a base station and a core network), and the MME is instructed to send second handover request signaling to a target base station, the second handover request signaling carrying flight path related information of an unmanned aerial vehicle.

In the present example, if a source base station and a target base station do not have an X2 interface, forwarding may be performed through the MME. Therefore, in the present example, the handover required signaling is sent to the MME through the S1 interface, realizing that during the handover process, even if the source base station and the target base station cannot directly transmit information, the target base station can obtain flight path related information.

The present example improves the handover required signaling and the second handover request signaling, so that the handover required signaling and the second handover request signaling may carry flight path related information, and transmission of the flight path related information during the handover process is realized.
