Resource management method and apparatuses for device to device communications
First Claim
1. A network topology management method for device to device (D2D) communication in a radio access network, adapted for a user equipment (UE), and the method comprising:
- requesting from the radio access network an authorization for D2D communication in a frequency spectrum through a non-mobile UE and a base station within the radio access network, wherein the non-mobile UE is within a radio range of the base station and is wirelessly connected to the radio access network through the base station;
receiving the authorization for D2D communication in the frequency spectrum, wherein the authorization comprises an identification (ID) information which comprises a static ID assigned by the radio access network if the UE is non-mobile and a temporary ID assigned by the radio access network if the UE is mobile;
engaging in the D2D communication in the frequency spectrum;
detecting a neighboring user equipment in proximity; and
repeating a step of “
collecting and reporting the static ID of the neighboring user equipment to the base station”
until a complete network topology of D2D UEs having static IDs is obtained.

Abstract
The present disclosure proposes a method for device to device communication and apparatuses using the same. More particularly, the present disclosure proposes a method and apparatuses to manage device to device (D2D) network resources based on maintain a user equipment (UE) network topology. The proposal includes a equipment (UE) requesting an authorization from the network for D2D communication in a licensed frequency spectrum, the UE would then receive through a control node or through another non-mobile UE the authorization which includes an identification (ID) information which allows the UE to engage in D2D communication in the license spectrum even when the UE is outside the range of the serving base station.

17. A network topology management method for device to device (D2D) communication in a radio access network, adapted for a base station within the radio access network, and the method comprising:
-
receiving a request for an authorization for D2D communication in a frequency spectrum, wherein receiving the request for the authorization for the D2D communication in the frequency spectrum from a first user equipment (UE); delivering the request for the authorization for the D2D communication to the radio access network; receiving the authorization for the D2D communication in the frequency spectrum from the radio access network; transmitting a first message comprising the authorization for D2D communication in the frequency spectrum, wherein the base station transmitting the first message to the first UE indirectly through a second UE within a radio range of the base station, wherein the authorization comprises an identification (ID) information which comprises a static ID assigned by the radio access network if the first UE is non-mobile and a mobile ID assigned by the radio access network if the first UE is mobile; receiving a report comprising a network topology information in response to transmitting the first message; and tracking the first UE according to the ID information of the first UE. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
