Abstract:
1. A method in a radio access arrangement operative in a wireless communication system for improving the balance between the capacity allocated to initial access for network entry and the capacity allocated to payloads in the radio access arrangement, the radio access arrangement being configured to operatively communicate with a plurality of mobile nodes via an air interface, said method comprises the steps of: setting an initial access capacity; obtaining a current initial access load; determining that the current initial access load exceeds a predetermined upper limit; temporarily increasing the initial access capacity provided by the radio access arrangement after a restart of the radio access arrangement in response to determining that the current initial access load exceeds the predetermined upper limit, wherein the step of temporarily increasing the initial access capacity comprises temporarily increasing the period during which each mobile node waits before sending a request to the radio access arrangement for a new association and/or a reestablished mobile node context; determining that the current initial access load is below a predetermined lower limit; and in response to determining that the current initial access load is below the predetermined lower limit: a) decreasing the initial access capacity provided by the radio access arrangement, and b) increasing a payload capacity provided by the radio access network.
