Embodiment Construction
[0017] figure 1 Shown is the process of the present invention automatically judging whether the user terminal supports low-rate services, including the following seven steps:
[0018] 1. Detect the Establishment Cause in the RRC Connection Request of the user, judge the service type of the user through the Establishment Cause, and enter step 2 when the Establishment Cause includes the packet service InteractiveCall or BackgroundCall. If not, the process terminates without further processing.
[0019] 2. Check the user's terminal support capability in the RRC Connection Setup Complete reported by the terminal, and check whether the service is supported on the FACH channel. If it is supported, go to step 3; if it is not supported, the service channel migration will not be performed, and the DCH / HS will always be used for services.
[0020] 3. Determine whether the user's real-time service rate is lower than the FACH channel admission threshold, if it is satisfied, then go to s...
