System and method for obtaining identity number of user equipment in an LTE system. An identity number of a user equipment may be obtained at an eNodeB in an LTE network having an MME. In order to obtain the identity number, the eNodeB may receive a first message from the user equipment and extract a first part of an identity number of the user equipment from the received first message. The eNodeB may receive a second message from the MME and extract a second part of the identity number of the user equipment from the second message. The eNodeB may form the identity number of user equipment by combining the extracted first part of the identity number with the extracted second part of the identity number.
