  • the SIB13 contains the MBSFN AreaId where the eMBMS service is currently being carried out on CELL1, or.
  • the SIB 15 contains the SAI information contained in the USD information.
  • the UE initiates a reselection to CELL2. If the condition for continuing to receive the service is not satisfied, the UE relinquishes the reselection to CELL2 and excludes CELL2 as a candidate for reselection.
  • the cell is in a period of time (300 seconds).
  • CELL2 is excluded as a candidate cell for reselection for a period of time.
  • the application layer AP deactivates the currently received service or reactivates other eMBMS services, the UE releases the restriction on CELL2 reselection.
  • Step 406 If reselection is initiated but the reselection fails, the UE directly uses the saved CELL1 control information to continue receiving the eMBMS service and recover the corresponding measurement.
  • Step 407 If the reselection succeeds, camping on the target cell, and continuing to receive the eMBMS service.
  • Figure 6 shows the resident process when the serving cell becomes unavailable in the multicast priority case, including:
  • Step 501 When the above reselection restriction condition causes the UE to fail to reselect a cell with better signal, and the current serving cell CELL1 becomes unavailable, the UE acquires the frequency that the USD and the system information SIB15 have the same frequency point and SAI. Resident. If the residency is successful, try the recovery of the eMBMS service.
  • Step 502 When the foregoing step cannot be camped on a suitable cell, perform discrete frequency frequency sweeping and camping according to the USD information, and try to recover the service.
  • the resident When the resident is successful, try to restore the eMBMS service, and still cannot When camping on a suitable cell, the frequency point information is swept and relocated according to the frequency information in the SIB15, and the service recovery is attempted.
  • the eMBMS service is attempted to be restored.
  • Step 503 Perform full-band scanning camping supported by the UE when the above steps are still unable to camp on the cell. Try to recover the eMBMS service when the residency is successful.

Abstract

L'invention concerne un procédé d'implémentation de réception continue dans un service de diffusion/multidiffusion multimédia amélioré (eMBMS), et un terminal l'utilisant. Le procédé comprend les étapes suivantes : un équipement utilisateur (UE) ajuste, d'après une description de service d'utilisateur (USD) et des informations système, une priorité de resélection de fréquence, et exécute ensuite un mesurage afin d'obtenir un résultat de mesurage; lorsqu'il est déterminé, d'après le résultat de mesurage, qu'une cellule voisine employant une fréquence eMBMS actuelle satisfait une condition de resélection, déterminer que la cellule voisine utilisant la fréquence eMBMS actuelle est une cellule cible; avant la resélection de la cellule cible, prédéterminer, selon une règle prédéfinie, une resélection de cellule afin d'obtenir un résultat de détermination comprenant : lorsque des informations système correspondant à la cellule cible comprennent des informations système associées d'un service eMBMS actuel, l'identification de la cellule cible en tant que cellule cible de resélection, et l'exécution d'un processus de resélection de cellule sur la cellule cible de resélection avec une priorité supérieure.
