Abstract
A datacenter, a communication apparatus, a communication method, and a communication control method in a communication system are provided that can enhance the versatility of a datacenter and a virtual network constructed therein. A communication system includes: a plurality of wireless communication facilities owned by a plurality of network operators, respectively; and a datacenter in which a virtual core network is constructed, wherein the virtual core network implements mobile communication functions by using the plurality of wireless communication facilities.
Claims9
A communication system comprising:
- a first wireless communication facility operated by a first mobile network operator, wherein the first wireless communication facility is connected to a user terminal subscribing to a first service provided by the first mobile network operator and subscribing to a second service provided by a mobile virtual network operator;
- and
- a datacenter operated by the mobile virtual network operator, wherein the datacenter is configured to:
- receive a bearer connection request from the user terminal to the datacenter through the first communication facility;
- establish a bearer between the user terminal and the datacenter based on the bearer connection request;
- terminate the bearer at a gateway positioned between the first wireless communication facility and a virtual core network in the datacenter;
- and
- distribute traffic, based on a network identifier of an outer header of the traffic, to the virtual core network or to a virtual network for a cloud service constructed separately in the datacenter.
A gateway in a datacenter, wherein the gateway is operated by a mobile virtual operator and is configured to:
- receive a bearer connection request from a user terminal to the datacenter through a first wireless communication facility operated by a first mobile network operator, wherein the first wireless communication facility is connected to the user terminal subscribing to a first service provided by the first mobile network operator and subscribing to a second service provided by the mobile virtual network operator;
- establish a bearer between the user terminal and the datacenter based on the bearer connection request;
- terminate the bearer at the gateway positioned between the first wireless communication facility and a virtual core network in the datacenter;
- and
- distribute traffic, based on a network identifier of an outer header of the traffic, to the virtual core network or to a virtual network for a cloud service constructed separately in the datacenter.
A communication method comprising:
- receiving a bearer connection request from a user terminal to a datacenter through a first wireless communication facility operated by a first mobile network operator, wherein the first wireless communication facility is connected to the user terminal subscribing to a first service provided by the first mobile network operator and subscribing to a second service provided by a mobile virtual network operation;
- establishing a bearer between the user terminal and the datacenter based on the bearer connection request;
- terminating the bearer at a gateway positioned between the first wireless communication facility and a virtual core network in the datacenter;
- and
- distributing traffic, based on a network identifier of an outer header of the traffic, to the virtual core network or to a virtual network for a cloud service constructed separately in the datacenter.
