Abstract
Provided are a state switching method, a network device and a terminal device. The method is used for a first terminal device in an inactive state; the inactive state indicates that the first terminal device and a network device are in a disconnection state, and the first terminal device and the network device retain context information of the first terminal device. The method includes: generating indication information, which is used to indicate the first terminal device to release the context information, or not to release the context information; and sending the indication information to the first terminal device.
Claims17
A state switching method, comprising:
- receiving, by a first terminal device, indication information sent by a network device, the first terminal device being in an inactive state indicating that the first terminal device and the network device are in a disconnection state, and the first terminal device and the network device retaining context information of the first terminal device, the indication information being used to indicate the first terminal device to release the context information, or not to release the context information;
- and
- determining whether to release the context information according to the indication information,
- wherein receiving, by the first terminal device, indication information sent by the network device comprises:
- receiving a bit sequence sent by the network device, the bit sequence comprising at least two bits corresponding to at least two terminal device groups each including a plurality of terminal devices, and data carried on each bit being used to indicate whether a terminal device in a corresponding terminal device group releases the context information;
- determining a first terminal device group to which the first terminal device belongs, the at least two terminal device groups comprising the first terminal device group;
- and
- obtaining a value carried on a first bit corresponding to the first terminal device group;
- wherein, determining whether to release the context information according to the indication information comprises:
- determining whether to release the context information according to the value carried on the first bit.
A network device, comprising a processor, a transceiver, and a non-transitory memory, wherein when code stored in the non-transitory memory is executed by the processor, the network device is caused to:
- generate, by the processor, indication information, the indication information being used to indicate a first terminal device to release context information, or not to release the context information;
- wherein the first terminal device is in an inactive state, the inactive state indicating that the first terminal device and the network device are in a disconnection state, and the first terminal device and the network device retain the context information of the first terminal device;
- and
- send, by the transceiver, the indication information to the first terminal device,
- wherein the processor is configured to:
- generate a bit sequence comprising at least two bits, the at least two bits corresponding to at least two terminal device groups each including a plurality of terminal devices, data carried on each bit being used to indicate whether a terminal device in a corresponding terminal device group releases the context information, and a first terminal device group in the at least two terminal device groups comprising the first terminal device;
- wherein the transceiver is configured to:
- send the bit sequence to the first terminal device.
A terminal device, comprising a processor, a transceiver, and a non-transitory memory, wherein when code stored in the non-transitory memory is executed by the processor, the terminal device is caused to:
- receive, by the transceiver, indication information sent by a network device, the indication information being used to indicate a first terminal device to release context information, or not to release the context information;
- wherein the first terminal device is in an inactive state indicating that the first terminal device and the network device are in a disconnection state, and the first terminal device and the network device retain the context information of the first terminal device;
- and
- determine, by the processor, whether to release the context information according to the indication information,
- wherein the transceiver is configured to:
- receive a bit sequence sent by the network device comprising at least two bits corresponding to at least two terminal device groups each including a plurality of terminal devices, and data carried on each bit being used to indicate whether a terminal device in a corresponding terminal device group releases the context information;
- wherein the processor is configured to:
- determine a first terminal device group to which the first terminal device belongs, the at least two terminal device groups comprising the first terminal device group;
- obtain a value carried on a first bit corresponding to the first terminal device group;
- and
- determine whether to release the context information according to the value carried on the first bit.
