Example Embodiment
[0057] Considering that when the ME randomly accesses the network, there will be network congestion. When the ME needs to re-access, it needs to adopt a different random access back-off time from the H2H terminal (ordinary terminal). In this embodiment, the ME uses the adjustment factor to adjust the reference back-off time to obtain the dedicated back-off time, and when re-initiating random access, it sends a random access request according to the dedicated back-off time. The back-off time or the preset back-off time constant used when the ordinary terminal re-initiates random access may be used as the reference back-off time. The network side carries the fallback time applicable to ordinary terminals in the random access response message, and the ME adjusts the fallback time received in the random access response message as its own dedicated fallback time; the fallback time constant can be preset in the ME, It can also be preset on the network side (such as the base station),...
