Abstract
A cell access method includes determining, by a terminal in communication with a first cell, to communicate with a second cell, establishing a wireless connection by which the terminal communicates with the second cell in response to the determining to communicate with the second cell, accessing the second cell on the wireless connection by the terminal, and receiving, by the terminal, a reconfiguration message sent by a first base station of the first cell. The reconfiguration message is sent by the first base station to the terminal. The method further includes reconfiguring the wireless connection according to the reconfiguration message, and communicating with the second cell on the reconfigured wireless connection.
Claims20
A terminal that communicates with a first cell, the terminal comprising:
- an interface circuit;
- a processor;
- and
- a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program having instructions to:
- determine to communicate with a second cell;
- establish a wireless connection by which the terminal communicates with the second cell in response to the determining to communicate with the second cell;
- access the second cell on the wireless connection;
- receive, through the interface circuit, a reconfiguration message sent by a first base station of the first cell, wherein the reconfiguration message is sent by the first base station to the terminal in response to the first base station determining, according to a terminal access indication message received by the first base station from a second base station of the second cell, that the terminal accesses the second cell, and further in response to the first base station determining that the second base station allows addition of the second cell as a cell communicating with the terminal;
- reconfigure the wireless connection according to the reconfiguration message;
- and
- communicate with the second cell on the reconfigured wireless connection.
A cell access method, comprising:
- determining, by a terminal in communication with a first cell, to communicate with a second cell;
- establishing a wireless connection by which the terminal communicates with the second cell in response to the determining to communicate with the second cell;
- accessing the second cell on the wireless connection by the terminal;
- receiving, by the terminal, a reconfiguration message sent by a first base station of the first cell, wherein the reconfiguration message is sent by the first base station to the terminal in response to the first base station determining, according to a terminal access indication message received by the first base station from a second base station of the second cell indicating that the terminal accesses the second cell, and further in response to the first base station determining that the second base station allows addition of the second cell as a cell communicating with the terminal;
- reconfiguring the wireless connection according to the reconfiguration message;
- and
- communicating with the second cell on the reconfigured wireless connection.
A base station, comprising:
- a processor;
- and
- a non-transitory computer readable medium having a program stored thereon for execution by the processor, the program having instructions to:
- communicating with a terminal in a first cell
- receiving a terminal access indication message from a second base station of a second cell indicating that the terminal accesses the second cell;
- determining, according to the terminal access indication message that the terminal accesses the second cell;
- determining that the second base station allows addition of the second cell as a cell communicating with the terminal;
- sending, to the terminal, a reconfiguration message wherein the reconfiguration message is sent by the first base station to the terminal in response to the determining that the terminal accesses the second cell, and further in response to the determining that the second base station allows addition of the second cell as the cell communicating with the terminal, wherein the sending the reconfiguration message causes the terminal to reconfigure the wireless connection according to the reconfiguration message and communicate with the second cell on the reconfigured wireless connection.
