Definitions

  • Embodiment 1 is a flowchart of another process of a dual mode terminal currently camping on a 2G cell and a dual mode terminal performing network selection according to Embodiment 3 of the present invention; A schematic structural diagram of a dual mode terminal provided in Embodiment 4 of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Embodiment 1 in order to improve the experience of the dual-mode terminal on the 3G network and improve the utilization of the 3G network resource, a network selection method for the dual-mode terminal is provided.
  • FIG. 1 is a network selection process of a dual mode terminal according to Embodiment 1 of the present invention.
  • the dual mode terminal searches for a 2G cell to determine whether there is a 2G cell that satisfies the camping condition.
  • the 3G network priority is set, for example, the TD-SCDMA network priority is set, that is, the dual-mode terminal performs the network selection process. , first choose 3G network.
  • the dual mode terminal completes the selection of the PLMN, the cell search and selection is started. Since 1880-1900MHz has just been assigned to the TD-SCDMA network in the 3G network.
  • the dual mode terminal continues to camp on the currently camped first 3G cell.
  • the dual mode terminal When the dual mode terminal is currently camped on the 3G cell, the dual mode terminal performs measurement in the idle mode.
  • the dual mode terminal performs measurement, the 3G cell adjacent to the location is measured to determine whether there is a currently camped 3G cell.
  • the dual-mode terminal can camp on the 3G cell with good condition and receive the 3G cell with good condition. service.
  • the dual mode terminal may continue to camp on the currently camped 3G cell when not present.
  • the physical layer of the GSM sorts and reports the measured GSM 'J, the area according to the measurement result, and the dual-mode terminal judges whether there is a first camper than the dual-mode terminal according to the ranking result of the GSM physical layer.
  • a GSM cell with good TD-SCDMA cell condition when there is a GSM cell, the dual mode terminal chooses to camp on the GSM cell, and receives the system message and broadcast sent by the GSM cell, when there is no current camping mode of the dual mode terminal
  • the dual mode terminal continues to camp on the first TD-SCDMA cell.
  • the SCDMA cell selects the GSM cell mode, selects whether there is a cell that satisfies the camping condition, and the camping condition is better than the current first TD-SCDMA cell condition, or can directly close the timer, and continues to select TD-SCDMA according to the first choice.
  • the cell selects a GSM cell mode to select whether there is a cell that satisfies the camping condition and has a better camping condition than the current first TD-SCDMA cell condition.
  • the embodiment of the present invention provides a network selection method for a dual mode terminal and a dual mode terminal.
  • the method searches for a 3G cell to determine whether there is a 3G cell that satisfies the camping condition.
  • the camping condition it resides in the said camping condition

Abstract

L'invention porte sur un procédé qui permet à un terminal bi-mode de sélectionner un réseau et sur un terminal bi-mode. Lesdits procédés et terminal sont utilisés pour résoudre le problème dans l'état de la technique selon lequel un utilisateur d'un terminal bi-mode a une mauvaise expérience sur le réseau de 3ème génération (3G). Le procédé comprend : lorsqu'un terminal bi-mode est mis sous tension, la recherche des cellules 3G et la détermination s'il existe ou non une cellule 3G satisfaisant les exigences de résidence; lorsqu'il existe une cellule 3G satisfaisant les exigences de résidence, la résidence dans la cellule 3G satisfaisant les exigences de résidence; sinon, la recherche des cellules de deuxième génération (2G) et la détermination s'il existe ou non une cellule 2G satisfaisant les exigences de résidence, et lorsqu'il existe une cellule 2G satisfaisant les exigences de résidence, la résidence dans la cellule 2G satisfaisant les exigences de résidence. Les cellules 3G sont recherchées en premier après que le terminal bi-mode de la présente invention a été mis sous tension, et lorsque aucune des cellules 3G ne satisfait les exigences de résidence, des cellules 2G seront recherchées, ce qui améliore l'expérience des utilisateurs de terminaux bi-modes sur le réseau 3G ainsi que le taux d'utilisation des ressources du réseau 3G.
