1. A method of operating a network infrastructure entity, the method comprising: mapping a set of data priorities to a set of radio bearers, each of said radio bearers of said set of radio bearers corresponding to a data priority of said set of data priorities; setting a minimum data priority below which low priority data having a priority below said minimum data priority should not be transmitted over any of said radio bearers, wherein said data is associated with a service; sending said minimum data priority to a mobile station along with a resource allocation, wherein prioritized data having a priority equal to or above said minimum data priority is allowed to be transmitted by said mobile station using said resource allocation; setting, by said network infrastructure entity, a time limit for which said mobile station may buffer said low priority data, wherein said mobile station may transmit said low priority data using said resource allocation after said time limit expires; and sending said time limit from said network infrastructure entity to said mobile station.
