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.
Claims8
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.
A method of communicating, the method comprising:
- performing, by a wireless terminal, a handover from a first base station to a second base station;
- transmitting, from the first base station to the second base station, information that indicates unsuccessfully transmitted downlink data volume;
- accumulating, by the second base station, information indicating a data volume for a report on a resource release;
- receiving, by the second base station, a request message related to the resource release from a core network;
- and
- in response to the receiving, transmitting, from the second base station to the core network, a total amount of the data volume.
A communication method in a communication system including a first base station and a second base station, the communication method comprising:
- communicating, by the first base station, with a wireless terminal;
- transmitting, by the first base station 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;
- accumulating, by the second base station, information indicating a data volume for a report on a resource release;
- and
- transmitting, from the second base station to a core network, a total amount of the data volume, when the second base station receives, from the core network, a request message related to the resource release.
A method of communicating by a base station, the method comprising:
- receiving from a second base station, information that indicates unsuccessfully transmitted downlink data volume, if a wireless terminal performs a handover from the second base station to the base station;
- accumulating the information indicating a data volume for a report on a resource release;
- and
- transmitting, to a core network, a total amount of the data volume when the base station receives, from the core network, a request message related to the resource release.
