Mobile communication system and communication method
First Claim
1. A method of communicating, the method comprising:
- transmitting, from a base station to a second base station, information that indicates unsuccessfully transmitted downlink data volume, if a wireless terminal performs a handover from the base station to the second base station;
the second base station accumulating information indicating a data volume for a report on a resource release;
the second base station receiving, from a core network, a request message related to the resource release; and
in response to the receiving the request message, the second base station transmitting, to the core network, a total amount of the data volume.

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.
