Abstract
Disclosed are a method for switching between access network devices, a terminal device, and a network device. The method includes the terminal device initiating a random access to a target access network device while maintaining a connection with a source access network device. The method also includes the terminal device releasing the connection with the source access network device, after successfully accessing to the target access network device and in response to channel quality of the source access network device meeting a preset condition.
Claims15
A method for switching between access network devices, comprising:
- initiating, by a terminal device, a random access to a target access network device while maintaining a connection with a source access network device;
- determining, by the terminal device, that the channel quality of the source access network device meets the preset condition, after successfully accessing to the target access network device;
- sending, by the terminal device, auxiliary information to the target access network device, wherein the auxiliary information is configured to indicate that the channel quality of the source access network device meets the preset condition;
- receiving, by the terminal device, response information of the auxiliary information, wherein the response information is configured to instruct the terminal device to release the connection with the source access network device;
- and
- releasing, by the terminal device, the connection with the source access network device according to the response information, wherein
- indication information is sent by the target access network device to the source access network device in response to receiving the auxiliary information, and
- the indication information is configured to indicate at least one of that:
- scheduling of downlink data is stopped by the source access network device;
- or data forwarding information is sent to the target access network device by the source access network device.
7 more elements
A terminal device comprising:
- a processor;
- and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute operations of:
- initiating, by the terminal device, a random access to a target access network device while maintaining a connection with a source access network device,
- determining, by the terminal device, that the channel quality of the source access network device meets the preset condition, after successfully accessing to the target access network device;
- sending, by the terminal device, auxiliary information to the target access network device, wherein the auxiliary information is configured to indicate that the channel quality of the source access network device meets the preset condition;
- receiving, by the terminal device, response information of the auxiliary information, wherein the response information is configured to instruct the terminal device to release the connection with the source access network device;
- and
- releasing, by the terminal device, the connection with the source access network device according to the response information, wherein
- indication information is sent by the target access network device to the source access network device in response to receiving the auxiliary information, and
- the indication information is configured to indicate at least one of that:
- scheduling of downlink data is stopped by the source access network device;
- or data forwarding information is sent to the target access network device by the source access network device.
9 more elements
A network device comprising:
- a processor;
- and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute operations of:
- after a target access network device is successfully accessed by a terminal device while maintaining a connection with a source access network device, receiving, by the network device, auxiliary information;
- and
- sending, by the network device, response information of the auxiliary information, wherein the response information is configured to instruct the terminal device to release the connection with the source access network device,
- wherein the network device is the target access network device, and the processor is further configured to call and run the computer program stored in the memory to execute an operation of:
- sending, by the target access network device, indication information to the source access network device in response to receiving the auxiliary information, wherein the indication information is configured to indicate at least one of that:
- scheduling of downlink data is stopped by the source access network device;
- or data forwarding information is sent to the target access network device by the source access network device.
