Abstract

The disclosure relates to a communication technique and system that fuse 5 th generation (5G) or pre-5G communication system with Internet of things (IoT) technology to support higher data transfer rate after 4th generation (4G) communication system, such as long term evolution (LTE). The disclosure applies to intelligent services (e.g., a smart home, a smart building, a smart city, a smart car or a connected car, healthcare, digital education, retail, security and safety related services, and the like) based on 5G communication technology and IoT related technology. A method and a device for supporting edge computing in a virtual radio access network are provided.

First claim

What is claimed is:

1. A device for performing a function of a distributed unit (DU) of a base station in a wireless communication, the device comprising:
a memory configured to store cache data related to an application executed by a terminal connected with the DU via a radio unit (RU); and
at least one processor configured to:
receive, from the terminal via the RU, a protocol data unit (PDU) for requesting data related to the application,
based on identifying that a quality indicator included in the PDU is related to mobile edge computing, identify whether requested data corresponds to the cache data,
based on the requested data corresponding to the cache data, transmit, via the RU, to the terminal, the cache data, and
based on the requests data distinct from the cache data:
transmit, to a server providing data related to the application, a request message to receive the requested data,
receive the requested data from the server providing data related to the application, and
transmit, to the terminal via the RU, the requested data.

2. The device of claim 1 , wherein the at least one processor is configured to, based on identifying that the quality indicator is not related to mobile edge computing, transmit, to the server, a request message to receive the requested data.

3. The device of claim 1 , wherein the request message is transmitted to the server via a core network including at least one of a user plane function (UPF) node, an access and mobility management function (AMF) node, a session management function (SMF) node, a unified data management (UDM) node, or a policy control function (PCF) node.

4. The device of claim 1 , wherein the cache data is updated through a representational state transfer application programming interface (REST API) based on receiving the requested data from the server.

5. A device for performing a function of a central unit (CU) of a base station in a wireless communication system, the device comprising:
a memory configured to store cache data related to an application executed by a terminal connected with the CU via a distributed unit (DU) and a radio unit (RU); and
at least one processor configured to:
receive, from the terminal via DU, a protocol data unit (PDU) for requesting data related to the application,
based on identifying that a quality indicator included in the PDU is related to a mobile edge computing, identify whether requested data corresponds to the cache data,
based on the requested data corresponding to the cache data, transmit, via the DU and the RU, to the terminal, the cache data, and
based on the requests data distinct from the cache data:
transmit, to a server providing data related to the application, a request message to receive the requested data,
receive the requested data from the server providing data related to the application, and
transmit, to the terminal via the DU and the RU, the requested data.

6. The device of claim 5 , wherein the at least one processor is configured to, based on identifying that the quality indicator is not related to the mobile edge computing, transmit, to the server, a request message to receive the requested data.

7. The device of claim 5 , wherein the request message is transmitted to the server via a core network including at least one of a user plane function (UPF) node, an access and mobility management function (AMF) node, a session management function (SMF) node, a unified data management (UDM) node, or a policy control function (PCF) node.

8. The device of claim 5 , wherein the cache data is updated through a representational state transfer application programming interface (REST API) based on receiving the requested data from the server.

9. A method performed by a device for performing a function of a distributed unit (DU) of a base station in a wireless communication system, the method comprising:
receiving, from a terminal via DU, a protocol data unit (PDU) for requesting data related to an application;
based on identifying that a quality indicator included in the PDU is related to a mobile edge computing, identifying whether requested data corresponds to cache data stored in memory of the device, cache data being related to the application executed by the terminal;
based on the requested data corresponding to the cache data, transmitting, via the DU and a radio unit (RU), to the terminal, the cache data; and
based on the requests data distinct from the cache data:
transmitting, to a server providing data related to the application, a request message to receive the requested data,
receiving the requested data from the server providing data related to the application, and
transmitting, to the terminal via the DU and the RU, the requested data.

10. The method of claim 9 , comprising, based on identifying that the quality indicator is not related to the mobile edge computing, transmitting, to the server, a request message to receive the requested data.

11. The method of claim 9 ,
wherein request message is transmitted to the server via a core network including at least one of a user plane function (UPF) node, an access and mobility management function (AMF) node, a session management function (SMF) node, a unified data management (UDM) node, or a policy control function (PCF) node.

12. The method of claim 9 , wherein the cache data is updated through a representational state transfer application programming interface (REST API) based on receiving the requested data from the server.

13. A method performed by a device for performing a function of a central unit (CU) of a base station in a wireless communication system, the method comprising:
receiving, from a terminal via DU, a protocol data unit (PDU) for requesting data related to an application;
based on identifying that a quality indicator included in the PDU is related to a mobile edge computing, identifying whether requested data corresponds to cache data;
based on the requested data corresponding to the cache data, transmitting, via the DU and a radio unit (RU), to the terminal, the cache data; and
based on the requests data distinct from the cache data:
transmitting, to a server providing data related to the application, a request message to receive the requested data,
receiving the requested data from the server providing data related to the application, and
transmitting, to the terminal via the DU and the RU, the requested data.

14. The method of claim 13 , comprising, based on identifying that the quality indicator is not related to the mobile edge computing, transmitting, to the server, a request message to receive the requested data.

15. The method of claim 13 ,
wherein request message is transmitted to the server via a core network including at least one of a user plane function (UPF) node, an access and mobility management function (AMF) node, a session management function (SMF) node, a unified data management (UDM) node, or a policy control function (PCF) node.

16. The method of claim 13 , wherein the cache data is updated through a representational state transfer application programming interface (REST API) based on receiving the requested data from the server.
