Abstract
A private network is flexibly built while ensuring physical or logical separation from a public network. A base station device notifies system information including a first identifier corresponding to a communication network (for example, PLMN) in an identifier list. In that state, a second identifier used locally is added to the identifier list of the system information according to control information from a control device. Thereafter, notification of the system information including the first and second identifiers in the identifier list is started. Therefore, the private network is built.
Claims15
A base station device, comprising:
- circuitry configured to:
- in a state of notification of system information that includes a first identifier corresponding to a first communication network in an identifier list;
- add a second identifier used locally to the identifier list according to first control information from a control device;
- and
- start notification of the system information that includes the first identifier and the second identifier in the identifier list;
- and
- in a state of the notification of the system information that includes the first identifier and the second identifier in the identifier list:
- delete the second identifier from the identifier list according to second control information from the control device;
- and
- start notification of the system information that does not include at least the second identifier in the identifier list.
A wireless communication system, comprising:
- a base station device that is connected to a first core network through a first backhaul line, wherein the base station device is configured to:
- in a state of notification of system information that includes a first identifier corresponding to a first communication network in an identifier list:
- add a second identifier used locally to the identifier list according to first control information from a control device;
- and
- start notification of the system information that includes the first identifier and the second identifier in the identifier list;
- and
- in a state of the notification of the system information that includes the first identifier and the second identifier in the identifier list:
- delete the second identifier from the identifier list according to second control information from the control device;
- and
- start the notification of the system information that includes the first identifier in the identifier list;
- and
- a wireless communication device configured to:
- receive the system information transmitted from the base station device;
- select one of the first identifier or the second identifier from the identifier list included in the system information;
- and
- make a connection request to the base station device based on the selected one of the first identifier or the second identifier.
A wireless communication device in which an identifier set including a set of identifiers not assigned to a network identifier is defined in advance, the wireless communication device comprising:
- a memory configured to store information associated with the identifier set;
- and
- circuitry configured to:
- acquire system information notified from a base station device;
- compare an identifier included in an identifier list of the acquired system information with an arbitrary identifier in the identifier set;
- and
- identify a first identifier based on the comparison, wherein
- the memory is further configured to:
- store information associated with an arbitrary second identifier that has already been assigned as the network identifier, and
- the circuitry is further configured to:
- select the arbitrary second identifier;
- compare the identifier included in the identifier list of the system information with the arbitrary second identifier;
- and
- perform an attach procedure to connect to a core network device belonging to the first identifier.
