2., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the 4th step of step 3 Scene one, if more than one of described above community, then TD-LTE is reselected to T
cell, ithat minimum community.
3., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the 4th step of step 3 Scene two, if more than one of described above community, then TD-SCDMA is reselected to T
cell, ithat minimum community.
4., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the 4th step of step 3 Scene three, if more than one of described above community, then GSM is reselected to T
cell, ithat minimum community.
5., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the TD-LTE low priority described in step 3 Scene one, the gravity treatment of 2/3G high priority: if 3G or the 2G adjacent area of high priority all meets Srxlev>Threshx_high_TDS+T within Treselection_TDS or the Treselection_GSM time
cell, ior Srxlev>Threshx_high_GSM+T
cell, i, then TD-LTE reselects to T
cell, ithat minimum community.
6., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the TD-SCDMA low priority described in step 3 Scene two, the gravity treatment of TD-LTE high priority: if the TD-LTE adjacent area of high priority all meets Srxlev>Threshx_high_TDL+T within the Treselection_TDL time
cell, i(i=1,2 ..., N), then TD-SCDMA reselects to T
cell, ithat minimum community.
7., as claimed in claim 1 based on the TD-LTE residence reselecting of load balancing and client perception, it is characterized in that: the GSM low priority described in step 3 Scene three, the gravity treatment of TD-LTE high priority: if the TD-LTE adjacent area of high priority all meets Srxlev>Threshx_high_TDL+T within the Treselection_TDL time
