An apparatus comprising:

• a processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• obtain mobility parameters corresponding to a mobile station during an initial time interval, the mobile station being located outside of a coverage area of the wireless network during the initial time interval;
• estimate a migration probability information in accordance with the mobility parameter and a migration probability table, wherein the migration probability information specifies a likelihood that the mobile station will migrate into the coverage area during a sequence of one or more time intervals following the initial time interval;
• and
• adjust a handover margin for the coverage area in accordance with the migration probability information, wherein the instructions to estimate the number of resource units required to support the service session of the mobile station during the sequence of one or more time intervals includes instructions to estimate a usage rate associated with a traffic type corresponding to the service session, to estimate a location of the mobile station within the coverage area at a first time interval in the sequence of one or more time intervals, to estimate a spectral efficiency of the location using a prediction function in accordance with instantaneous load conditions of the wireless network, and to estimate the number of resource units required to support the service session in accordance with the estimated usage rate and the estimated spectral efficiency.

An apparatus comprising:
