Definitions

  • the present invention relates to the field of communications technologies, and in particular, to a cell handover method and a terminal.
  • a DRX (Discontinuous Reception) mechanism is usually adopted.
  • the DRX mechanism is a receiving mechanism adopted by the Long Term Evolution (LTE) system to reduce the power consumption of the terminal. It introduces a periodic opening and closing mechanism of a radio frequency (RF) module to enable the radio frequency module to be in an on or off state, thereby periodically monitoring a physical downlink control channel (PDCCH), which is unnecessary.
  • RF radio frequency
  • the PDCCH is continuously monitored to achieve the purpose of reducing UE power consumption.
  • FIG. 1 is a schematic diagram of a principle of a DRX mechanism in a prior art LTE system.
  • the On Duration (continuous listening period) indicates a time period during which the terminal monitors the PDCCH channel, in which the radio channel of the UE is turned on and continuously monitors the PDCCH; except for the time other than the On Duration, the UE radio module is turned off. To achieve the purpose of saving electricity.
  • the On Duration is periodically generated, and the specific period is implemented by an eNB (evolved Node B) configuration. While the terminal is saving power, in order to avoid excessive communication delay between the eNB and the terminal, the concepts of long cycle and short cycle are introduced. On a short period, On duration occurs more frequently than a long period.
  • the LTE system has designed a variety of timers, and combined with the HARQ (Hybrid Automatic Repeat Request) process, the operation process under the DRX mechanism is given.
  • the related timers include: 1. Inactive Timer Inactivity Timer: When the terminal receives the control signaling of the initial transmission of HARQ during the On duration, the timer is turned on, and the terminal continuously monitors the control channel before the timer expires. If the terminal receives the control signaling of the initial transmission of HARQ before the Inactivity Timer expires, it will terminate and restart.
  • RTT Timer Only applicable to DL (downstream). The terminal will turn on this timer if it receives control signaling for HARQ retransmission. If the data in the corresponding HARQ process is still unsuccessfully decoded after the previous HARQ transmission, after the RTT Timer timer expires, the terminal turns on the retransmission timer Retransmission Timer. If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission, the terminal does not start the Retransmission Timer after the RTT Timer timer expires. 3. Retransmission Timer: During the retransmission timer, the terminal listens to the control channel and waits for retransmission of the corresponding HARQ process.
  • the On duration Timer is turned on.
  • the eNB schedules the DL initial transmission at time t1, so the Inactivity Timer starts and the HARQ RTT Timer is turned on.
  • the Inactivity Timer first times out.
  • the HARQ RTT Timer times out.
  • the Retransmission Timer is started.
  • the eNB schedules the first retransmission, so the Retransmission Timer is stopped and the RTT Timer is started.
  • the RTT Timer times out, and the first retransmission at time t4 is still unsuccessful (the terminal feeds back NACK), so the Retransmission Timer starts.
  • the eNB schedules a second retransmission, the Retransmission Timer is stopped, and the RTT Timer is started. Since the second retransmission is successful (the terminal feedback acknowledges the ACK), the Retransmission Timer will not be started after the RTT Timer expires.

Abstract

L'invention concerne un procédé de transfert intercellulaire de cellule et un terminal. Le procédé comprend les étapes suivantes : un terminal obtient un résultat de mesure pour un transfert intercellulaire dans le cycle de réception discontinue (DRX) en cours, et lorsqu'il est déterminé que le résultat de mesure est inférieur à un premier seuil prédéfini, déterminer la durée d'un cycle DRX correspondant au résultat de mesure selon une plage de paramètres à laquelle appartient le résultat de mesure et une relation de mise en correspondance entre une plage de paramètres prédéfinie et la durée du cycle DRX, et mettre à jour la durée du cycle DRX en cours selon la durée du cycle DRX ; et lorsqu'il est déterminé que le résultat de mesure est supérieur ou égal au premier seuil prédéfini, le terminal effectue une opération de transfert intercellulaire. Les modes de réalisation de la présente invention présentent l'avantage de réduire un retard temporel lorsqu'un terminal effectue un transfert intercellulaire de cellule et d'améliorer l'efficacité de transfert intercellulaire de cellule.
