If the difference of the serving cell signals of the adjacent detection period is continuously N-1 times in the N detection periods is greater than the high-speed threshold, then It is determined that the current speed is high speed; if the difference of the serving cell signals of the adjacent detection period is continuously N-1 times in the N detection periods is less than the high speed threshold and greater than the medium speed threshold, it is determined that the current speed is the medium speed.
  • a specified threshold this threshold refers to a high-speed threshold or a medium-speed threshold.
  • Step 3 The UE adjusts a cell reselection parameter threshold according to the current speed determination result.
  • the UE adds the sf-High to the base station to perform the cell reselection threshold. If the UE is the medium-speed, the UE needs to send the base station to perform the cell reselection. Add sf-Medium based on the cell reselection threshold.
  • Step 4 The UE performs the cell reselection process according to the adjusted cell reselection parameter threshold.
  • the application example 2 sends the UE speed determination criterion to the UE in the system parameter message of the cell. After receiving the speed determination criterion sent by the base station, the UE in the connected state determines the current moving speed and adjusts the cell handover parameter.
  • Step 1 The base station sends a UE speed determination criterion in the UE measurement configuration message according to the system configuration, and the criterion is described in a Mobility State Parameters cell.
  • the specific method is the same as that in the first application example.
  • Step 2 After receiving the speed determination criterion sent by the base station, the UE determines the current moving speed according to the determination criterion, and the specific determination manner is the same as that in the application example 1, and details are not described herein again.
  • Step 3 The UE adjusts a cell handover trigger duration according to the current speed determination result.
  • the UE needs to multiply the cell handover trigger duration determined by the base station by sf-High when performing the neighbor cell measurement; if the UE is the medium-speed, the UE needs to determine the cell determined by the base station when performing the neighbor cell measurement. Multiply the trigger trigger time by sf-Medium.
  • the above technical solution can improve the accuracy and timeliness of UE speed judgment, improve the network switching success rate, and improve user experience. Therefore, the present invention has strong industrial applicability.

Abstract

La présente invention se rapporte à un procédé, à un terminal et à un système adaptés pour ajuster un paramètre sur la base d'une vitesse de déplacement d'un terminal. Le procédé selon l'invention comprend les étapes suivantes : un terminal mobile détecte l'intensité de signal d'une cellule de desserte ; le terminal mobile détermine une vitesse de déplacement actuelle sur la base de critères de détermination de vitesse qui sont délivrés en sortie par une station de base ; et le terminal mobile ajuste un paramètre du système sur la base de la vitesse de déplacement, le paramètre du système étant un paramètre de seuil de resélection de cellule ou un paramètre de durée d'une commande de commutation. Au moyen de la solution technique décrite : la précision et l'opportunité de la détermination de la vitesse de l'UE sont améliorées ; le taux de réussite de la commutation réseau est amélioré ; et l'expérience de l'utilisateur est elle aussi améliorée.
