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 receiver configured to receive, from another base station during a handover from the another base station to the base station, information indicating a volume of unsuccessfully downlink data;
- a controller configured to accumulate the volume for a report on a resource release;
- and
- a transmitter configured to transmit the accumulated volume to a core network, when the base station receives, from the core network, a request message related to the resource release.
A method of a base station in communication with a wireless terminal, the method comprising:
- receiving, from another base station during a handover from the another base station to the base station, information indicating a volume of unsuccessfully transmitted downlink data;
- accumulating the volume for a report on a resource release;
- and
- upon receipt, from a core network, of a request message related to the resource release, transmitting the accumulated volume to the core network.
A wireless terminal, comprising:
- a transceiver configured to communicate with a first base station;
- and
- a controller configured to perform a handover from the first base station to a second base station, wherein the second base station comprises:
- a receiver configured to receive from the first base station information indicating a volume of unsuccessfully transmitted downlink data, during a handover from the first base station to the second base station;
- a controller configured to accumulate the volume for a report on a resource release;
- and
- a transmitter configured to transmit the accumulated volume to a core network, when the base station receives, from the core network, a request message related to the resource release.
A method of a wireless terminal, the method comprising:
- communicating with a first base station;
- performing a handover from the first base station to a second base station;
- wherein the second base station:
- receives, from the first base station, information indicating a volume of unsuccessfully transmitted downlink data during a handover from the first base station to the second base station;
- accumulates the volume for a report on a resource release;
- and
- transmits the accumulated volume to a core network, when the base station receives, from the core network, a request message related to the resource release.
