Embodiment Construction
[0040] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0041] combine image 3 , this figure simulates the process of cross-area call transfer of field terminals. At this time, the overlapping coverage base stations of base station 3 are base stations 1, 2, 4, and 5. Assuming that the terminal is handed over from base station 3 to base station 5, the implementation process is described below:
[0042] Receive status:
[0043]The terminal locks on base station 3. After establishing a smooth group call, it goes online to traffic channel 1 of base station 3, and detects the field strength of traffic channel 1 of base station 3. When the field strength is weaker than the set value, the scanning overlaps and covers the base station. The sequence is carried out according to the order in which the four overlapping coverage base stations are written in the switching table, and the corresponding traffic channel...
