Abstract

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for obtaining traffic information by a terminal in a wireless communication system. The method comprises the steps of: broadcasting a first D2D discovery signal requesting traffic information to a plurality of first surrounding terminals; receiving, in response to the first D2D discovery signal, a second D2D discovery signal indicating surrounding traffic information from one or more second surrounding terminals among the plurality of first surrounding terminals; and updating the traffic information of the surrounding area on the basis of the one or more second D2D discovery signals.

First claim

What is claimed is:

1 . A method for acquiring traffic information by a UE in a wireless communication system, comprising:
broadcasting a first device-to-device (D2D) discovery signal requesting traffic information to a plurality of first neighboring UEs; receiving, in response to the first D2D discovery signal, one or more second D2D discovery signals indicating traffic information from one or more second neighboring UEs from among the plurality of first neighboring UEs; and updating traffic information of a surrounding area on the basis of the one or more second D2D discovery signals.

2 . The method according to claim 1 , further comprising receiving additional traffic information about the one or more second neighboring UEs from an eNB,
wherein the traffic information of the surrounding area is updated on the basis of the traffic information and the additional traffic information.

3 . The method according to claim 1 , wherein the traffic information of the surrounding area is updated on the basis of a distribution of positions of the one or more neighboring UEs transmitting the one or more second D2D discovery signals per response time.

4 . The method according to claim 1 , wherein the one or more neighboring UEs correspond to UEs satisfying predetermined traffic conditions from among the plurality of first neighboring UEs,
wherein the traffic information of the surrounding area is updated using the predetermined traffic conditions and position information of the one or more second neighboring UEs.

5 . The method according to claim 1 , further comprising overlaying the updated traffic information of the surrounding area on a display of a vehicle navigation system displaying traffic maps.

6 . A UE used in a wireless communication system, comprising:
a radio frequency (RF) unit; and a processor, wherein the processor is configured to broadcast a first D2D discovery signal requesting traffic information to a plurality of first neighboring UEs, to receive, in response to the first D2D discovery signal, one or more second D2D discovery signals indicating traffic information from one or more second neighboring UEs from among the plurality of first neighboring UEs and to update traffic information of a surrounding area on the basis of the one or more second D2D discovery signals.

7 . The UE according to claim 6 , wherein the processor is configured to receive additional traffic information about the one or more second neighboring UEs from an eNB,
wherein the traffic information of the surrounding area is updated on the basis of the traffic information and the additional traffic information.

8 . The UE according to claim 6 , wherein the traffic information of the surrounding area is updated on the basis of a distribution of positions of the one or more neighboring UEs transmitting the one or more second D2D discovery signals per response time.

9 . The UE according to claim 6 , wherein the one or more neighboring UEs correspond to UEs satisfying predetermined traffic conditions from among the plurality of first neighboring UEs,
wherein the traffic information of the surrounding area is updated using the predetermined traffic conditions and position information of the one or more second neighboring UEs.

10 . The UE according to claim 6 , wherein the processor is configured to overlay the updated traffic information of the surrounding area on a display of a vehicle navigation system displaying traffic maps.
