<p>A method of handover in carrier aggregation scenario is proposed in the present invention. In an embodiment of the present invention, the following steps are comprised: a base station sends a handover command to a user equipment wherein the handover command includes information for indicating a Peell and a Scell requiring a timing advance different from said Peell; the user equipment receives the handover command, and performs a random access on said Peell and the Seell requiring a timing advance different from said Peell; the base station sends information for indicating corresponding timing advance to said user equipment, according to a successful random access of said user equipment on said Peell and the Seell requiring a timing advance different from said Peell. By means of the technical solution provided in the present invention, the Peell and the Seell requiring a timing advance in carrier aggregation scenarios can fee supported. In addition, in some embodiments, by supporting changing Peell, the success rate of handover in carrier aggregation, scenarios is effectively improved, as to avoid unnecessary connection reestablishment procedures.</p> |
