Abstract

The present disclosure provides a method for resource reconfiguration and the corresponding device. A method provided in a first aspect of the present disclosure comprises: at a controller for managing a baseband unit (BU) pool, determining system status and resource usage conditions of the BU pool; based on the system status and the resource usage conditions, identifying a resource that needs to be reconfigured, the resource being selected from a virtual machine running on a server in the BU pool or from a processing module in an accelerator in the BU pool; determining an address of a target device using the resource, wherein the target device is selected from servers or accelerators in the BU pool; and instructing the target device to reconfigure the resource. The solution of the present disclosure effects reconfiguration of all resources in cloud RAN.

First claim

What is claimed is:

1. A method for resource reconfiguration, comprising:
at a controller for managing a baseband unit (BU) pool, determining system status and a resource usage condition of the BU pool;
identifying a resource to be reconfigured based on the system status and the resource usage condition, the resource being selected from a virtual machine running on a server in the BU pool or from a processing module in an accelerator in the BU pool;
determining an address of a target device using the resource, the target device being selected from the server or the accelerator in the BU pool;
sending an indication of reconfiguration of the resource to the target device, the indication including a signal for triggering the reconfiguration of the resource and a reconfiguration file or an identification of a reconfiguration file previously received by the target device indicating a modification to be made to the hardware of the resource; and
receiving a feedback signal from the target device, the feedback signal being based on a parsing of the signal for triggering the reconfiguration and the reconfiguration file or the identification of the reconfiguration file, to determine whether there is an error in the signal, the identification or the reconfiguration file, the feedback signal indicating whether there is successful reconfiguration or that there was an error in the signal, the identification or the reconfiguration file.

2. The method according to claim 1 , further comprising:
in response to the feedback signal indicating that the reconfiguration is unsuccessful, sending, to the target device, an indication of terminating the reconfiguration of the resource.

3. A method for resource reconfiguration, comprising:
receiving an indication of reconfiguration of hardware of a resource from a controller for managing a baseband unit (BU) pool, the hardware of the resource being selected from virtual hardware of a virtual machine running on a server in the BU pool or from actual hardware of a processing module in an accelerator in the BU pool, the indication of reconfiguration include a signal for triggering the reconfiguration of the resource and a reconfiguration file or an identification of a previously received reconfiguration file indicating a modification to be made to the hardware of the resource; and
performing the reconfiguration of the resource based on the indication, wherein performing the reconfiguration includes parsing the signal and the reconfiguration file or the identification of the reconfiguration file to determine whether there is an error in the signal, the identification or the reconfiguration file;
in response to determining that there is an error in the signal, the identification or the reconfiguration file, sending to the controller a feedback signal indicating that the reconfiguration is unsuccessful; and
in response to determining that the signal and the reconfiguration file or the identification of the reconfiguration file are correct, applying the modification to the hardware of the resource.

4. The method according to claim 3 , wherein the reconfiguration file is received, further comprising:
storing the reconfiguration file.

5. An electronic device, comprising:
at least one memory including computer program code; and
at least one processor, coupled to the memory, the memory and the computer program code configured to, with the at least one processor, cause the electronic device to at least perform actions comprising:
determining system status and a resource usage condition of a baseband unit (BU) pool;
identifying a resource to be reconfigured based on the system status and the resource usage condition, the resource being selected from a virtual machine running on a server in the BU pool or from a processing module in an accelerator in the BU pool;
determining an address of a target device using the resource, the target device being selected from the server or the accelerator in the BU pool;
sending an indication of reconfiguration of the resource to the target device, the indication including a signal for triggering the reconfiguration of the resource and a reconfiguration file or an identification of a reconfiguration file previously received by the target device indicating a modification to be made to the hardware of the resource; and
receiving a feedback signal from the target device, the feedback signal being based on a parsing of the signal for triggering the reconfiguration and the reconfiguration file or the identification of the reconfiguration file, to determine whether there is an error in the signal, the identification or the reconfiguration file, the feedback signal indicating whether there is successful reconfiguration or that there was an error in the signal, the identification or the reconfiguration file.

6. The electronic device according to claim 5 , the actions further comprising:
in response to the feedback signal indicating that the reconfiguration is unsuccessful, sending, to the target device, an indication of terminating reconfiguration of the resource.

7. An electronic device, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the electronic device to at least:
receive an indication of reconfiguration of a resource from a controller for managing a baseband unit (BU) pool, the resource being at least a part of the hardware of the at least electronic device, the indication of reconfiguration include a signal for triggering the reconfiguration of the resource and a reconfiguration file or an identification of a previously received reconfiguration file indicating a modification to be made to the hardware of the resource; and
perform the reconfiguration of the resource based on the indication, wherein performing the reconfiguration includes parsing the signal and the reconfiguration file or the identification of the reconfiguration file to determine whether there is an error in the signal, the identification or the reconfiguration file;
in response to determining that there is an error in the signal, the identification or the reconfiguration file, sending to the controller a feedback signal indicating that the reconfiguration is unsuccessful; and
in response to determining that the signal and the reconfiguration file or the identification of the reconfiguration file are correct, applying the modification to the hardware of the resource.
