Patent Images
1. A base station, comprising:
- a data storage unit configured to temporarily store user data, when the base station transmits and receives the user data to and from a mobile station;
an identifier adding unit configured to add, to the user data stored in the data storage unit, a transfer identifier which indicates that the user data is transferred to another base station by a handover, when the mobile station performs the handover from the base station to the other base station;
a data transfer unit configured to transfer, to the other base station through a transfer apparatus, the user data to which the transfer identifier is added;
a judgment unit configured to judge a radio access scheme of the other base station; and
a priority level determination unit configure to determine a transfer priority of the user data based on a judgment result of the radio access scheme,wherein the identifier adding unit is configured to add, to the user data stored in the data storage unit, the transfer identifier in accordance with the transfer priority.

5. A data transfer method used in a base station, comprising:
-
storing user data temporarily, when the base station transmits and receives the user data to and from a mobile station; adding, to the stored user data, a transfer identifier which indicates that the user data is transferred to another base station by a handover, when the mobile station performs the handover from the base station to the other base station; transferring, to the other base station through a transfer apparatus, the user data to which the transfer identifier is added; judging a radio access scheme of the other base station; and determining a transfer priority of the user data based on a judgment result of the radio access scheme, wherein in adding the transfer identifier, the transfer identifier in accordance with the transfer priority is added to the user data stored in the data storage unit. - View Dependent Claims (6, 7, 8)
