Patent ID: 8478284

Claim:
An apparatus comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions configured to, with the at least one processor, direct the apparatus at least to: control radio communication using communication resources for user data communication and control resources to indicate assignment of the communication resources; cause allocation of mobile stations to use at least one of a dynamic allocation and a persistent allocation, wherein each allocation defines a different utilization of the control resources and the communication resources in a radio system; cause monitoring of one or more reallocation conditions associated with at least one of the dynamic allocation and the persistent allocation; and cause reallocation of at least one mobile station in an instance in which at least one of the one or more reallocation conditions is fulfilled; wherein the reallocation condition associated with the persistent allocation is a number of reserved communication resources in the radio system exceeding a predetermined threshold value, the predetermined threshold value being based on system performance, and wherein the apparatus is further directed to cause reallocation, in an instance in which the reallocation condition associated with the persistent allocation is fulfilled, of at least one of the mobile stations from the persistent allocation to the dynamic allocation.
