Resource controller for resource management in a telecommunication network

A method for resource management in a telecommunication network, the telecommunication network providing a first set of resources for cellular communication and a second set of resources for direct device-to-device communication between user equipment (UE), the method comprising:

• requesting a measurement be performed by at least one UE, the measurement indicating a capacity utilization of the second set of resources and comprising a wait period of the at least one UE for usage of the second set of resources;
• adapting at least one of:
• (i) the first set of resources, or (ii) the second set of resources as a function of the measurement;
• receiving a bearer setup message from a first UE for the establishment of a connection to a second UE, the bearer setup message indicating missing resources for device-to-device communication;
• and
• determining whether to reconfigure the second set of resources and inform the first UE accordingly, wherein the first UE (i) establishes a device-to-device communication, or (ii) performs a connection establishment for cellular communication.

A user equipment (UE) for direct device-to-device communication, comprising:

• a processor configured to:
• receive a measurement request for capacity utilization from a resource management device,
• measure a capacity utilization associated with the UE, the capacity utilization comprising a wait period of the UE for usage of a second set of resources,
• provide the capacity utilization to the resource management device,
• receive a message indicating a reconfiguration of a resource pool according to the capacity utilization,
• select, based on the message, a communication resource from the resource pool that was reconfigured, and
• in response to receiving a bearer setup reject message with an indication of a changed resource allocation to establish a device-to-device communication, send, to the resource management device, a bearer setup message for the establishment of a connection to a second UE, the bearer setup message indicating missing resources for device-to-device communication.

A method performed in a user equipment (UE) for establishing device-to-device communication, the method comprising:

• receiving a measurement request for capacity utilization from a resource management device;
• measuring a capacity utilization associated with the UE, the capacity utilization comprising a wait period of the UE for usage of a second set of resources;
• providing the capacity utilization to the resource management device;
• receiving a message indicating a reconfiguration of a resource pool according to the capacity utilization;
• selecting, based on the message, a communication resource from the resource pool that was reconfigured;
• and
• in response to receiving a bearer setup reject message with an indication of a changed resource allocation to establish a device-to-device communication, sending, to the resource management device, a bearer setup message for the establishment of a connection to a second UE, the bearer setup message indicating missing resources for device-to-device communication.
