The technical scheme of the invention is further described by combining the drawings and specific embodiments:
when the existing 5G user equipment is switched, if the mapping relationship between the Qos Flow and the data bearer changes, the data stored in the Buffer of the original base station can only be discarded, and seamless switching cannot be achieved. In this embodiment, according to the mapping relationship between the Qos Flow and the RB, the user equipment side keeps converting the original mapping relationship to the new mapping relationship for the downlink data target base station within a certain time, and the user equipment side corresponds the old mapping relationship to the new mapping relationship for the data in the uplink data buffer within a certain time.
The switching forward mechanism of the downlink data: data in a PDCP (Packet Data Convergence Protocol) Buffer already contains QoS Flow ID information, when handover occurs, a Data Packet is forwarded (Data Forwarding) to a target RAN (Radio Access Network) base station side, the target base station issues the Data Packet to a user equipment according to a new RB, the user equipment side receives the QoS Flow in the corresponding RB, and the QoS Flow ID allocated by the original base station and the QoS Flow ID allocated by the new base station contained in the Data Packet at this time are inconsistent, which causes the Data to be forwarded to an incorrect IP receiving port, leading to invalid forwarded Data and failing to achieve seamless handover.
In order to solve the above problem, the present embodiment provides the following processing mechanism:
qos _ flow processing mechanism a, as shown in fig. 2: and if the RB is inconsistent with the corresponding Qos Flow ID and the old Qos Flow ID is not enabled in the new cell, setting that the service bearer corresponding to the uplink Reflective Qos does not act at the moment, and processing according to the RB corresponding to the new Qos Flow ID. And when the Flow ID message in the message of the target cell is received is the newly allocated ID, restoring the configuration of the Reflective Qos to take effect, and entering a normal receiving state.
Qos _ flow processing mechanism b, as shown in fig. 3: and if the RB is inconsistent with the corresponding Qos Flow ID and the old Qos Flow ID is enabled in the new cell, setting the Reflective Qos as invalid, forwarding data according to the IP port number of the user equipment of the data message, and if the new Qos Flow ID is received, restoring and configuring the Reflective Qos to be in an effective state.
Fig. 4 shows the statistical calculation of the receiving timer, when the timer T _ receive is started to record the starting time Ti1, when the old Qos Flow ID is received, the new Flow ID is remapped, when the new Flow ID message is received, the time Ti2 is recorded, the Qos Flow ID remapping mechanism is exited, the receiving is performed normally, and the timeout T _ new is calculated as Ti2-Ti 1. And when the T _ receive is overtime, recording the time T1, exiting the Qos Flow ID processing mechanism, and calculating the average time delay T _ avg for processing the abnormal Flow ID.
Fig. 5 is a state machine for receiving the remapped Qos Flow at the ue side.
This embodiment provides a processing mechanism for explaining how the user equipment handles data forwarded by the source base station (including the Qos Flow ID of the source cell) when the Qos Flow ID changes during handover.
And after the user equipment side is switched to the target cell, carrying out Flow ID mapping on the Qos Flow ID in the received data message according to the Qos Flow ID allocated by the target cell for the data message forwarded by the source cell until the data message containing the new QoS Flow ID is received or the receiving timer is overtime.
The user equipment side provides a self-statistics learning mechanism for receiving the timer T _ receiver, and calculates and corrects the time length required by switching data forwarding each time, namely, the value of the remapped timer T _ receiver through the statistics mechanism for processing each time.
The embodiment is only carried out at the user equipment side, and the network side does not need to be modified, so that the implementation cost is low. And the user equipment side has the time delay of self-statistics learning switching Flow ID remapping, the parameter does not need to be preset or network configuration, and the method has good adaptability.
