FREQUENCY LAYER DISPERSION

摘要

User Equipment (UE) in receipt of a session start signal indicating a session frequency to use for a session along with other user equipment uses the session frequency until a session stop message is received and then changes to a frequency selected to avoid subsequent use of a same frequency used by the other user equipment. For instance, when the UE receives a Multimedia Broadcast Multicast Service (MBMS) session start signal and it contains a preferred frequency, the Radio Resource Control (RRC) layer of the UE could store the frequency of the serving cell for later reference. The UE then converges to the preferred frequency for the duration of the session. When the UE receives a session stop, RRC layer retrieves the previously stored information about the pre-session frequency and requests the physical layer (L1) to select a cell on the frequency where it was previously camped on.
