Step 104：UE is based on the target frequency point, and RR channel request messages (RR_CHANNEL_ is sent to network
REQUEST)。
Step 105：UE receives network replies IM message, and the RR channels of network distribution are obtained by IM message.
In the above process, UE sends RR_CHANNEL_REQUEST to believe to network request random access channel, namely RR
Road, hereafter, UE wait network replies IA message, however, due to network congestion, UE does not receive what network issued always
