a communication module (CM) configured to generate an initial network entry request;

an antenna assembly configured to find, in response to the initial network entry request, a satellite based on a search of a sky, wherein the search of the sky comprises sequentially changing a beam pointing direction of the antenna assembly, wherein the satellite is assigned to downlink to a geographic cell associated with the user terminal; and

a media access control (MAC) layer component configured to generate an uplink radio frame including a random access channel (RACH) request associated with the initial network entry request at a particular portion of the uplink radio frame for the satellite, wherein the CM is configured to generate the initial network entry request via a connection manager component, wherein the user terminal uses a same temporary service identifier for the initial network entry request as a second user terminal that initiates another network entry request at approximately a same time as the initial network entry request, wherein the user terminal selects a temporary service identifier independent of other user terminals and the satellite, and wherein the user terminal resends a request to initiate network entry.
