For ease of illustration, various descriptions herein are provided to conform to 3GPP in the communication system 100; however, the subject matter of the present disclosure is not limited in this regard and the embodiments disclosed herein may be advantageously applied to other wired or wireless communication protocols or networks. For example, in an embodiment in which the core/access network 120 includes a UTRAN, the NB 126 may take the form of an RNC, which may be configured to communicate with the UEs 132, 134, or 136. In an embodiment where the core/access network 120 includes a GERAN, the eNB 124 may represent a base station controller (BSC) configured to communicate with the UEs 132, 134, or 136 via a base transmission station (BTS).

In various embodiments, the UE 132 may access the core/access network 120 via a radio link with a base station, e.g., eNB 124. A downlink (DL) transmission may be a communication from the eNB 124 to the UE 132. An uplink (UL) transmission may be a communication from the UE 132 to the eNB 124. Only limited numbers of UEs and eNBs are illustrated in FIG. 1 for ease of illustration. However, the communication system 100 may include any number of UEs, eNBs, or other servers while practicing suitable embodiments of the present disclosure. As an example, in some embodiments, the core/access network 120 may also include other servers, such as a machine type communication (MTC) server (not shown) to facilitate MTC.
