Apparatus and method for device-to-device communication route establishment in a mobile communication system
First Claim
1. A method, comprising:
- determining that a remote node is within radio coverage of a mobile node;
determining, in the mobile node, a need to transmit a data message to a destination node;
transmitting a request message to a base station;
receiving from the base station a reply message comprising a route to the destination node, the route comprising at least an identifier of the remote node;
transmitting, to the base station, a request for a radio resource for radio communication between the mobile node and the remote node;
receiving, from the base station, an assignment of the radio resource to the mobile node; and
transmitting the data message to the remote node using the radio resource.

Abstract
The invention concerns a method and an apparatus for device-to-device communication route establishment within a mobile communication system. In the method a mobile node determines that a remote node is within radio coverage of the mobile node. The mobile node determines a need to transmit a data message to a destination node. The mobile node transmits a request message to the base station. In reply the mobile node receives a message including a route to the destination node. The route includes at least an identifier of the remote node. The mobile node obtains a radio resource for radio communication between the mobile node and the remote node from the base station. Thereupon, the mobile node transmits the data message to the remote node using the radio resource obtained.

20. A non-transitory computer-readable medium having machine instructions stored therein, the instructions when executed by at least one processor, cause the at least one processor to:
-
determine that a remote node is within radio coverage of a mobile node; determine a need to transmit a data message to a destination node; transmit a request message to a base station; receive from the base station a reply message comprising a route to the destination node, the route comprising at least an identifier of the remote node; transmit, to the base station, a request for a radio resource for radio communication between the mobile node and the remote node; receive, from the base station, an assignment of the radio resource to the mobile node; and transmitting the data message to the remote node using the radio resource.
