Abstract

Facilitating fast return to stand alone advanced networks (e.g., 5G, 6G, and beyond) after voice fall back is provided herein. Operations of a method can comprise receiving, from a first network device and by a second network device, a connection request that comprises an indication of a fall back procedure. The fall back procedure can be an “RRC release and redirect” or an “IRAT Handover.” The method also can comprise facilitating control of the voice communication for the mobile device and triggering a release of the control of the mobile device from the second network device based on a determination that the voice communication has completed. The fast return procedure can be either a “RRC release and redirect’ or an “IRAT handover.” Further, the method can comprise redirecting the mobile device to a third network device selected based on a capability of the mobile device.

First claim

What is claimed is:

1 . A method, comprising:
receiving, from first network device by a second network device comprising a memory and a processor, a connection request that comprises an indication of a fall back procedure, wherein the connection request is associated with a mobile device via which a voice communication is scheduled to occur; facilitating, by the second network device, control of the voice communication for the mobile device; triggering, by the second network device, a release of the control of the mobile device from the second network device based on a determination that the voice communication has completed at the mobile device; and redirecting, by the second network device, the mobile device to a third network device selected based on a capability of the mobile device.

2 . The method of claim 1 , wherein the receiving the indication of the fall back procedure comprises receiving an information element that comprises an evolved packet system return request.

3 . The method of claim 2 , wherein the information element is a first information element, and wherein the redirecting the mobile device to the third network device comprises receiving a second information element that comprises redirected carrier information.

4 . The method of claim 1 , further comprising:
prior to the triggering the release of the mobile device, evaluating, by the second network device, the capability of the mobile device based on the determination that the voice communication has completed at the mobile device.

5 . The method of claim 4 , wherein the evaluating the capability of the mobile device comprises determining the mobile device is able to support communication with a defined band on a standalone network.

6 . The method of claim 1 , wherein the determination is a first determination, and wherein the redirecting the mobile device to the third network device comprises:
determining that multiple advanced network bands are supported by the mobile device; and selecting an advanced network band from the multiple advanced network bands based on a second determination that the advanced network band comprises a priority that satisfies a defined priority level as compared to other advanced network bands of the multiple advanced network bands other than the advanced network band.

7 . The method of claim 1 , wherein the triggering the release of the mobile device comprises evaluating an occurrence of a defined event.

8 . The method of claim 7 , wherein the defined event is the voice communication being a voice communication that originated from the first network device.

9 . The method of claim 1 , wherein the first network device is a network device configured to operate according to a fifth generation wireless network communication protocol.

10 . The method of claim 1 , wherein the second network device is deployed in a standalone deployment architecture.

11 . The method of claim 10 , wherein the first network device is a network device configured to operate according to a long term evolution network communication protocol.

12 . The method of claim 1 , wherein the connection request is a radio release control connection request.

13 . The method of claim 1 , wherein the first network device and the third network device are a same network device.

14 . The method of claim 1 , wherein the first network device and the third network device are different network devices.

15 . A system, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
controlling a first communication for a user equipment based on a connection request that comprises an indication of a fall back procedure, wherein the connection request is associated with the user equipment via which the first communication is scheduled to occur, and wherein the connection request is received from network equipment;
releasing a first control of the user equipment based on a determination that the first communication has completed at the user equipment; and
redirecting the user equipment to the network equipment for a second control of a second communication scheduled to occur at the user equipment.

16 . The system of claim 15 , wherein the indication comprises a first information element that comprises an evolved packet system return request, and wherein the redirecting the user equipment comprises receiving a second information element that comprises redirected carrier information.

17 . The system of claim 15 , wherein the operations further comprise:
prior to the releasing the control of the user equipment, evaluating a capability of the user equipment based on the determination that the first communication has completed at the user equipment, wherein the evaluating the capability comprises determining the user equipment is able to support communication with a defined band on a standalone network.

18 . A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of the executable instructions, comprising:
determining a first communication of a mobile device is to be controlled by a first network device based on a connection request that comprises an indication of a fall back procedure; facilitating a control of the first communication by the first network device for a duration of the first communication; facilitating a release of the control of the mobile device by the first network device based on a determination that the first communication has completed at the mobile device; and transferring the control of the mobile device to a second network device based on a capacity of the mobile device.

19 . The non-transitory machine-readable storage medium of claim 18 , wherein the determination is a first determination, and wherein the transferring the control of the mobile device to the second network device comprises:
determining that multiple advanced network bands are supported by the mobile device; and selecting an advanced network band from the multiple advanced network bands based on a second determination that the advanced network band comprises a priority that satisfies a defined priority level as compared to other advanced network bands of the multiple advanced network bands other than the advanced network band.

20 . The non-transitory machine-readable storage medium of claim 18 , wherein the indication comprises a first information element that comprises an evolved packet system return request, and wherein the redirecting the mobile device comprises receiving a second information element that comprises redirected carrier information.
