A method of controlling access to a telecommunications network is disclosed. One of a plurality of commercial UEs receives an SIB2 signal from the network. The SIB2 includes a threshold signal BF (0<BF<1) representative of network load at a given time, and a time signal BT. In response to the received SIB2, the commercial UE generates a random number RD1, between 0 and 1. The random number RD is compared with the threshold value BF and, where the value RD1 for the commercial UE is below the threshold BF, the commercial UE is denied access to the network. If the random number exceeds the threshold value BF, the commercial UE is permitted access to the network. Emergency Services UEs have priority access. The value BF is dynamically changed such that, at times of relatively higher network load, there is a relatively lower probability of the commercial UEs in the network being permitted access to the network, than the probability of access for those commercial UEs when there is a relatively lower network load. ES UEs receive priority access at all times. |
