Abstract
This application provides a handover method and apparatus. User equipment UE obtains configuration information from a base station, where the configuration information indicates to transmit a handover complete message in a procedure of accessing a target cell; and transmits, based on the configuration information, the handover complete message in the procedure of accessing the target cell.
Claims27
A handover method, applied to user equipment UE handing over to a target cell, wherein the method comprises:
- obtaining configuration information from a base station, wherein the configuration information indicates to transmit a handover complete message in a procedure of accessing the target cell;
- and
- transmitting, based on the configuration information, the handover complete message in the procedure of accessing the target cell;
- wherein the configuration information comprises:
- random access preamble information and information about a resource for transmitting the random access preamble information, wherein
- the random access preamble information is specifically used for indicating to transmit a handover complete message in a procedure of randomly accessing the target cell ;
- wherein the transmitting the handover complete message in the procedure of accessing the target cell further comprises:
- sending an Msg1 carrying preamble information to the target cell in a first available random access channel slot after reception of a handover command, or no later than an Nth available random access channel slot after reception of a handover command, wherein N is an integer.

A handover method, applied to a base station to which a target cell performing a handover procedure belongs, wherein the method comprises:
- sending configuration information in response to handover of user equipment UE from a source cell to the target cell being triggered, wherein the configuration information indicates to transmit a handover complete message in a procedure of accessing the target cell;
- wherein the configuration information comprises:
- random access preamble information and information about a resource for transmitting the random access preamble information, wherein
- the random access preamble information is specifically used for indicating to transmit the handover complete message in the procedure of accessing the target cell.

A handover method, applied to a base station to which a source cell performing a handover procedure belongs, wherein the method comprises:
- determining, in response to a measurement result reported by user equipment UE, a target cell for performing the handover procedure;
- and
- transmitting, in response to obtaining configuration information from the target cell, the configuration information to the UE, wherein the configuration information indicates to transmit a handover complete message in a procedure of accessing the target cell;
- wherein the configuration information comprises:
- random access preamble information and information about a resource for transmitting the random access preamble information, wherein
- the random access preamble information is specifically used for indicating to transmit the handover complete message in the procedure of accessing the target cell.
