Method of reducing connection set-up delay

The invention relates to method, device and retards the pressure-sensitive data of substrates are launched by predict according responds for transmitting a connection is arranged on the signal to base station subsystem from the terminal (50, 51, 52, 53 and 54) in turn arranged on early uplink wireless connection, and emitting the delay sensitive data via the early uplink connected, wherein in the delay sensitive service wireless power system came from user terminal is the same of uplink information. The region is further provided user terminal and a wireless power system (1).
