Abstract

Various embodiments disclosed herein that facilitate a dynamic self-backhaul reconnection using a radio resource control messaging. According to some embodiments, a system can comprise detecting a failure in a first backhaul communication link with a first node device, wherein the first node device is communicatively connected to a core network device of a core network, selecting a second node device, other than the first node device, that is communicatively connected to the core network device for establishment of a second backhaul communication link to replace the first backhaul communication link, and facilitating establishing a first connection with the second node device to provide an indication of the failure of the first backhaul communication link, to provide a confirmation that the second node device is available in connection with establishment of the second backhaul communication link, and to request to reserve resources to establish the second backhaul communication link with the second node device.

Claims (58)

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:

detecting a failure in a first communication link with first node equipment, wherein the first node equipment is communicatively connected to network equipment;

selecting second node equipment, other than the first node equipment, that is communicatively connected to the core network equipment, for establishment of a second communication link to replace the first communication link; and

facilitating establishing a first connection with the second node equipment to:

provide an indication of the failure of the first communication link,

provide a confirmation that the second node equipment is available in connection with establishment of the second communication link, and

request to reserve resources to establish the second communication link with the second node equipment.

2. The system of claim 1 , wherein the operations further comprise:

determining whether the second node equipment is available to establish the second communication link prior to providing the indication to the network; and

in response to the determining that the second node equipment is available to establish the second communication link, transmitting a first message using a first bandwidth, wherein the first message comprises a status request, a status update, a bandwidth request, and location information of the second node equipment.

3. The system of claim 2 , wherein selecting the second node equipment comprises identifying the second node equipment based on an evaluation of signal strengths of different node equipment and tuning to the second node equipment.

4. The system of claim 1 , wherein facilitating the establishing of the first connection comprises facilitating the establishing of a wireless connection employing a first bandwidth that carries signaling information.

5. The system of claim 1 , wherein the operations further comprise:

receiving a recommended partition that facilitates establishing the second communication link with the second node equipment; and

establishing the second communication link utilizing the recommended partition.

6. The system of claim 1 , wherein the operations further comprise:

transmitting a confirmation of establishment of the second communication link with the second node equipment.

7. The system of claim 1 , wherein the first communication link comprises a first backhaul communication link, wherein the network equipment is core network equipment, and wherein the operations further comprise:

transmitting a self-backhaul request message comprising:

a status request,

a self-backhaul status update message comprising an indication of the failure in the first communication link,

a self-backhaul bandwidth request message comprising a request for bandwidth, and

a self-backhaul location request message comprising location information of the second node equipment.

8. A method, comprising:

detecting, by equipment comprising a processor, a failure in a first communication link with first node equipment communicatively connected to network equipment;

selecting, by the equipment, second node equipment, different than the first node equipment, that is communicatively connected to the network equipment for establishment of a second communication link to replace the first communication link; and

facilitating, by the equipment, establishing a connection with the second node equipment to provide an indication of the failure of the first communication link, to provide a confirmation that the second node equipment is available to establish the second communication link, and to request resources to establish the second communication link with the second node equipment.

9. The method of claim 8 , further comprising:

determining, by the equipment, whether the second node equipment is available to establish the second communication link prior to providing the indication.

10. The method of claim 8 , further comprising;

identifying, by the equipment, the second node equipment based on an evaluation of signal strengths of different node equipment; and

tuning, by the equipment, to the second node equipment.

11. The method of claim 8 , wherein facilitating the establishing of the connection comprises facilitating the establishing a wireless connection employing a first bandwidth that carries signaling information.

12. The method of claim 8 , further comprising:

receiving, by the equipment, a recommended partition that facilitates establishing the second communication link.

13. The method of claim 8 , further comprising:

transmitting, by the equipment, a first connection confirmation that the second communication link with the second node equipment has been established.

14. The method of claim 8 , further comprising:

transmitting, by the equipment, a first message using a first bandwidth, wherein the first message comprises a status request, a failed connection with the connected node equipment, a bandwidth request, and location information of the second node equipment.

15. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

detecting a failure in a first communication link with connected node equipment, wherein the connected node equipment is communicatively connected to a network equipment;

selecting a donor node equipment, other than the connected node equipment, that is communicatively connected to the network equipment for establishment of a second communication link to replace the first communication link; and

facilitating establishing a connection with the donor equipment to provide an indication of the failure of the first communication link, to provide a confirmation that the donor node equipment is available to establish the second communication link, and to request resources to establish the second communication link with the donor node equipment.

16. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

determining whether the donor node equipment is available to establish the second communication link prior to providing the indication.

17. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

identifying the donor node equipment based on an evaluation of signal strengths of different node equipment; and

tuning to the donor node equipment.

18. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

receiving a recommended partition that facilitates establishing the second communication link.

19. The non-transitory machine-readable medium of claim 15 , wherein the operations further comprise:

receiving a recommended partition that facilitates establishing the second communication link with the donor node equipment;

establishing the second communication link utilizing the recommended partition; and

transmitting a first message indicating that the second communication link with the donor node equipment has been established.

20. The non-transitory machine-readable medium of claim 15 , wherein the first communication link comprises a first communication link, wherein the network equipment comprises core network equipment, and wherein the operations further comprise:

transmitting a first self-backhaul request message comprising a status request, a second self-backhaul status update message comprising an indication of the failure in first communication link, a third self-backhaul bandwidth request message comprising a request for bandwidth and a fourth self-backhaul location request message comprising location information of the second node equipment.
