IMPROVING CHARGING INFORMATION ACCURACY IN A TELECOMMUNICATIONS NETWORK

摘要

The invention relates to a method for improving charging information accuracy in a telecommunications network with respect to a target user equipment, wherein the telecommunications network comprises a core network, a first base transceiver station and a second base transceiver station, wherein the target user equipment receives data traffic from the core network in the form of data packets, the data traffic being related to a data connection established between the target user equipment and the telecommunications network, wherein in case that the target user equipment camps on the telecommunications network using the first base transceiver station, the first base transceiver station comprises a first non-delivered packet data volume information, the first non-delivered packet data volume information being specific to the target user equipment and related to data packets to be sent to the target user equipment but unsuccessfully transmitted to the target user equipment, wherein in case that the target user equipment camps on the telecommunications network using the second base transceiver station, the second base transceiver station comprises a second non-delivered packet data volume information, the second non- delivered packet data volume information being specific to the target user equipment and related to data packets to be sent to the target user equipment but unsuccessfully transmitted to the target user equipment, wherein in case of a handover or cell change procedure from the first base transceiver station to the second base transceiver station regarding the target user equipment, the first non-delivered packet data volume information is transmitted from the first base transceiver station to the second base transceiver station and is taken into account for determining the second non-delivered packet data volume information, the first non- delivered packet data volume information being transmitted from the first base transceiver station to the target user equipment and from the target user equipment to the second base transceiver station.
