Abstract
The present disclosure provides a method and a device for cell handover, and a method for a terminal device to establish a PDCP entity during a handover process. The method includes: establishing a first Packet Data Convergence Protocol (PDCP) entity, the first PDCP entity being configured for communication between a terminal device and a target cell base station; and releasing a second PDCP entity, the second PDCP entity being configured for communication between the terminal device and a source cell base station. Time at which the second PDCP entity is released is not earlier than time at which the first PDCP entity is established.
Claims19
A method for cell handover, comprising:
- establishing a first Packet Data Convergence Protocol (PDCP) entity, the first PDCP entity being configured for communication between a terminal device and a target cell base station;
- and
- releasing a second PDCP entity, the second PDCP entity being configured for communication between the terminal device and a source cell base station, wherein time at which the second PDCP entity is released is not earlier than time at which the first PDCP entity is established.
A network device, wherein the network device is a source cell base station and comprises a processing unit configured to:
- release a second Packet Data Convergence Protocol (PDCP) entity, the second PDCP entity being configured for communication between a source cell base station and a terminal device, wherein time at which the second PDCP entity is released is not earlier than time at which a first PDCP entity is established by the terminal device, the first PDCP entity being configured for communication between the terminal device and a target cell base station.
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 invoke and execute the computer program stored in the memory to:
- establish a first Packet Data Convergence Protocol (PDCP) entity, the first PDCP entity being configured for communication between a terminal device and a target cell base station;
- and
- release a second PDCP entity, the second PDCP entity being configured for communication between the terminal device and a source cell base station, wherein time at which the second PDCP entity is released is not earlier than time at which the first PDCP entity is established.
