Abstract
A mobile communication system which can transfer information on the number of packets counted up until then by a base station of a mobile source, to a base station of a mobile target, even when a terminal performs a handover. UE moves to a Target eNode B, but a Source eNode B decides to perform a handover, and the Source eNode B includes information on the number of packets counted up until then in a Handover Request message to the Target eNode B, so as to notify the Target eNode B. After receiving a Handover Confirm message from the UE, the Target eNode B includes information on the number of packets received from the Source eNode B in a Handover Complete message transmitted to a CN Node, so as to notify the CN Node.
Claims12
A base station for communicating with a wireless terminal, the base station comprising:
- a transmitter for transmitting to a second base station information that indicates unsuccessfully transmitted downlink data volume, if the wireless terminal performs a handover from the base station to the second base station.
A wireless terminal, comprising:
- hardware;
- means implemented at least by the hardware for communicating with a first base station;
- and
- means implemented at least by the hardware for performing a handover from the first base station to a second base station, wherein the first base station comprises:
- a transmitter for transmitting to the second base station information that indicates unsuccessfully transmitted downlink data volume, if the wireless terminal performs the handover from the first base station to the second base station.
A wireless communication system, comprising:
- a first base station;
- a second base station;
- and
- a wireless terminal, wherein
- the first base station communicates with the wireless terminal, and
- the first base station comprises a transmitter for transmitting to the second base station information that indicates unsuccessfully transmitted downlink data volume, if the wireless terminal performs a handover from the first base station to the second base station.
