Abstract
Claims
1. A radio base station comprising one or more second devices connected to a first device, wherein the second device includes a transmitting unit that transmits a transition request to another second device connected to another first device requesting a transition of a terminal to another cell, and a receiving unit that receives a response to the transition request from the other second device.
2. The wireless base station according to claim 1, wherein the transmitting unit transmits a sequence number state request of the packet data convergence protocol layer to the first device.
3. The radio base station according to claim 1, wherein the receiving unit receives timing-related information, including a timing adjustment value for transmission by the terminal, from the other second device, and the transmitting unit transmits a cell switching notification to the other second device after receiving the timing-related information.
4. A radio base station comprising one or more second devices connected to a first device, wherein the second device includes a transmitting unit that transmits a transition request message to the first device indicating that a terminal needs to transition to another cell, and a receiving unit that receives a transition instruction message from the first device after transmitting the transition request message.
5. The radio base station according to claim 4, wherein the receiving unit receives timing-related information, including a timing adjustment value for transmission by the terminal, from another second device, and the transmitting unit transmits a cell switching notification to the other second device after receiving the timing-related information.
6. A radio base station comprising a first device, wherein one or more second devices are connected to the first device, the first device comprising a transmitting unit that transmits a transition request to the second device requesting a terminal to transition to another cell, and a receiving unit that receives a response from the second device to the transition request.
