Abstract
A mobile communications system including a network with a source network node and a target network node that supports a handover procedure, and a mobile terminal that is allowed to access the source network node and access the target network node according to the handover procedure, in which information related to a reception status of user data is delivered between at least two among a group including the mobile terminal, the source network node, and the target network node such that the target network node may receive status information from the source network node and the target network node may receive a status report from the mobile terminal.
Claims6
A method of data transfer management for a wireless communications system, the method comprising:
- receiving, by a source network node comprising a medium access control (MAC) entity and a radio link control (RLC) entity, a measurement report from a terminal;
- deciding, by the source network node, a handover based on the received measurement report;
- receiving, by the source network node, a new cell radio network temporary identifier (C-RNTI) corresponding to the terminal from a target network node for the handover;
- and
- transmitting, by the source network node, a reception status report to the target network node,
- wherein the reception status report is for informing the target network node of at least incorrectly received uplink data from the terminal, or both correctly and incorrectly received uplink data from the terminal.
A network node comprising:
- a medium access control (MAC) entity;
- and
- a radio link control (RLC) entity,
- wherein the network node receives a measurement report from a terminal and decides a handover based on the received measurement report,
- wherein the network node receives a new cell radio network temporary identifier (C-RNTI) corresponding to the terminal from a target network node for the handover,
- wherein the network node transmits a reception status report to the target network node, and
- wherein the reception status report is for informing the target network node of at least incorrectly received uplink data from the terminal, or both correctly and incorrectly received uplink data from the terminal.
