example 1

[0079] Figure 6 It is a flowchart of a method for transmitting V2X communication resource configuration during handover according to an optional embodiment of the present invention. The method is an embodiment of UE1 performing V2X transmission through the Uu interface, as shown in Figure 6 As shown, the steps of the method include:

[0080] Step S602: The source base station eNB1 decides to perform handover based on the X2 interface according to the measurement report and radio resource management information reported by the equipment unit.

[0081] Step S604: the source base station selects the target base station, and sends a handover request message to the target base station.

[0082] Wherein, the handover request may carry V2X transmission interest indication information.

[0083] Step S606: the target base station sends a handover request confirmation message to the source base station, wherein the handover command that triggers the handover of the equipment unit ca...

[0091] Figure 7 It is a flowchart of a method for a base station to obtain V2X communication resources of neighboring base stations through an X2 interface and send them to a UE through a system broadcast message according to an optional embodiment of the present invention, as shown in Figure 7 As shown, the steps of the method include:

[0092] Step S702: eNB1 interacts with eNB2 through X2 interface signaling to obtain the V2X communication resource configuration of eNB2;

[0093] For example, eNB1 can obtain the V2X communication resource configuration of eNB2 through the X2 interface setup request or X2 setup response message, or eNB1 can obtain the PC5 communication resource of eNB2 through the base station configuration update message of the X2 interface.

[0094] Step S704: the base station eNB1 sends the V2X communication resource configuration information of the neighboring cell eNB2 to the UE1 through a system broadcast message.

[0095] Wherein, the system broad...

[0098] Figure 8 It is a flowchart of a method for a base station to send a V2X communication abnormal sending / receiving resource pool in a system broadcast message according to an optional embodiment of the present invention, as shown in Figure 8 As shown, the steps of the method include:

[0099] Step S802: the base station sends the V2X communication abnormal transmission / reception resource pool of the serving cell to UE1 in a system broadcast message;

[0100] Step S804: If UE1 initiates RRC connection establishment and wants to enter connected state for V2X communication;

[0101] Step S806: If the T300 runs and / or the timeout of the T300 causes the connection establishment to fail, the UE can use the V2X communication abnormal sending / receiving resource pool in the system broadcast message to perform V2X communication on the PC5 interface.

Abstract

The invention provides a resource configuration method and an apparatus thereof. The method comprises the following steps that a first base station acquires a PC5 communication resource of a second base station, and / or, acquires the PC5 communication resource of the first base station itself; and the first base station sends the acquired PC5 communication resource to user equipment. In the invention, a problem of how to guarantees V2X service continuity by UE which carries out V2X message transmission through a Uu port when a switching or abnormal condition is generated is solved in the correlation technology so that low-delay and high-reliability vehicle networking information transmission is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource configuration method and device. Background technique [0002] Vehicle-to-Everything Communications (V2X for short) refers to the provision of vehicle information through sensors, vehicle-mounted terminals and electronic tags mounted on vehicles, and the use of various communication technologies to achieve vehicle-to-vehicle communication (Vehicle-to-Vehicle Communications). Communication, V2V for short), Vehicle-to-Pedestrian Communications, V2P for short, Vehicle-to-Infrastructure Communications, V2I for short, Vehicle-to-Network Communications, referred to as V2N) communication, and extract and share information effectively on the information network platform, effectively control vehicles and provide comprehensive services. [0003] Currently, 3GPP is discussing V2X based on (Long Time Evolution, LTE for short). Based on the other party participating in the comm...
