Abstract
A communication control method is a method for selecting a candidate cell in which a relay node exists in a cellular communication system. The communication control method includes transmitting, by a node configured to manage a cell, a first information element indicating whether selection of the cell is barred, and a second information element regarding whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed when the selection of the cell is barred. The first information element is applied to both the relay node and a user equipment. The transmitting includes transmitting the second information element for the relay node as an information element different from the second information element for the user equipment.
Claims5
A communication control method for selecting a candidate cell in which a predetermined node exists in a cellular communication system, the communication control method comprising:
- transmitting, by a node configured to manage a cell, a master information block including a first information element and a second information element, the first information element indicating whether selection of the cell is barred, the second information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for a user equipment when the selection of the cell is barred
- transmitting a system information block including a third information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for the predetermined node being different from the user equipment when the selection of the cell is barred,
- determining, by the predetermined node, whether the selection of another cell belonging to a frequency identical to a frequency of the cell is allowed based on the third information element rather than based on the second information element, and
- selecting, by the predetermined node, the candidate cell based on the determining step.
A predetermined node that is not a user equipment, the node comprising:
- a processor and a memory, and
- a receiver configured to receive a master information block including a first information element and a second information element, the first information element indicating whether selection of the cell is barred, the second information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for a user equipment when the selection of the cell is barred,
- the receiver configured to receive a system information block including a third information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for a predetermined node being different from the user equipment when the selection of the cell is barred, and
- the processor configured to:
- determine whether the selection of another cell belonging to a frequency identical to a frequency of the cell is allowed based on the third information element rather than based on the second information element, and
- select the candidate cell based on the above determining.
A chipset provided in a predetermined node that is not a user equipment, the chipset comprising
- a processor and a memory,
- the processor configured to manage a cell, and
- receive a master information block including a first information element and a second information element, the first information element indicating whether selection of the cell is barred, the second information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for a user equipment when the selection of the cell is barred,
- the processor is configured to receive a system information block including a third information element indicating whether selection of another cell belonging to a frequency identical to a frequency of the cell is allowed for a predetermined node being different from the user equipment when the selection of the cell is barred, and
- the processor configured to:
- determine whether the selection of another cell belonging to a frequency identical to a frequency of the cell is allowed based on the third information element rather than based on the second information element, and
- select the candidate cell based on the above determining.
