Method of cell re-selection in multimedia broadcast multicast service (MBMS) system after MBMS session stop
Abstract:
Cell re-selection for a mobile terminal in a single frequency layer includes determining termination of a multicast broadcast multimedia service (MBMS) session in that frequency layer and checking for availability of stored information relating to a previously used frequency. If this information is available, then a check of the validity of stored information is made. If this information is not available or is not valid, then the mobile station selects a frequency from the SIB 11/12 list and attempts cell selection on a suitable cell on the selected frequency. If the cell selection attempt is not successful, then initial cell selection procedures are carried out to determine to which cell the terminal should move.
