[0024] refer to figure 1 , the present invention comprises the following steps to the detection of handover failure scene:
[0025] Step 1. When the wireless link fails and the mobile terminal loses connection with the serving base station, it will generate RRCConnectionReestablishment Request Message information. For the process of generating information, refer to figure 2 as follows:
[0026] (1a) After the mobile terminal loses connection with the serving base station, it reads the base station signal detection list generated by the signal detection of the surrounding base stations. If the measured values of all the base station signals in the list are lower than the threshold value, it indicates that the wireless link fails. The reason is the coverage hole. The information field ReestablishmentCause selects the coverage hole. If the base station signal measurement value in the list is higher than the threshold value, it indicates that the wireless link failure occurs b...
