Patent ID: 8774211

Claim:
A method implemented by a base station in a wireless access network, the method comprising: receiving, by the base station and from a network operation center (NOC), multiple backoff period definitions for sending a re-access request to the base station by multiple classes of mobile terminals associated with the wireless access network, wherein the multiple classes are distinguished based on a last hexadecimal value of a Mobile Station Identification Number (MSIN) assigned to the mobile terminal; storing, in a memory associated with the base station, the multiple backoff period definitions; selecting, by the base station and based on a particular network condition, one of the multiple backoff period definitions to control a sequence of radio resource control (RCC) re-access requests from the multiple classes; sending over a broadcast channel, by the base station and to mobile terminals within a signal range of the base station, the selected one of the multiple backoff period definitions, wherein the selected one of the multiple backoff period definitions includes a class randomizer variable and wherein the one of the one or more backoff period definitions is applied differently by different mobile terminals based on application of the MSIN to the class randomizer variable; and receiving, by the base station and from the mobile terminals, RCC re-access requests sequenced by the multiple classes based on the selected one of the multiple backoff period definitions.
