1. A method for a contention-based random access procedure, comprising:
receiving, by a base station, a first scheduled transmission message of a mobile terminal, wherein the first scheduled transmission message comprises a medium access control (MAC) control element including a mobile terminal contention resolution identity;
in response to receiving the first scheduled transmission message, setting up, by the base station, a contention resolution message, wherein the base station is an eNodeB of a 4G LTE network, wherein the contention resolution message is configured for transmission from the base station to the mobile terminal, wherein the contention resolution message comprises a defined part of a hash value of the mobile terminal contention resolution identity, wherein the hash value of the mobile terminal contention resolution identity is calculated by the base station using a hash algorithm, and wherein the defined part of the hash value is inserted by the base station into the contention resolution message; and
transmitting, by the base station, the contention resolution message to the mobile terminal.
