In the cooperation of TD-SCDMA and GSM, the strategy of current system bearing is: if the TD signal satisfies resident condition, preferential resident TD network, wherein, the TD network is the abbreviation of TD-SCDMA network, if the TD signal do not satisfy resident condition, the zone not yet covered with networks as TD, terminal can gravity treatment or is switched to the GSM network; After UE switched to the GSM network from the TD network, if the service ending of GSM network, terminal can be earlier resident at the GSM network, during if the TD signal satisfies resident condition, terminal gravity treatment is again returned the TD network.
In the switching of TD network and GSM network,, accurate FR(Fast Return has been proposed in order to improve the success rate of subscriber paging) technology.Concrete, if terminal carries out in the professional process at the TD network, it is better to monitor the GSM network signal, and in the process that the TD network signal progressively dies down, terminal switches to the GSM network from the TD network.Terminal can detect the TD network signal according to the network information and whether satisfy resident condition after the GSM calling network finishes, if the TD network signal satisfies resident condition, terminal directly gravity treatment is returned the TD network, reduces the off-grid time, improves the success rate of paging.
Wherein, the network information comprises: the signal quality threshold information that the TD network is returned in frequency point information that the TD Web broadcast is relevant and gravity treatment.This network information is before terminal switches to the GSM network by the TD network, by network side notice end side, therefore, terminal is after the GSM calling network finishes, can the signal strength signal intensity of the frequency that provides in the network information be detected, when its signal strength signal intensity reaches the signal quality thresholding, judge that it satisfies the resident condition of TD network signal, otherwise do not satisfy.
But at present terminal only detects the signal strength signal intensity of preceding 9 frequencies in the frequency point information, and the frequency of TD network is considerably beyond 9, so the configuration of frequency is most important.
During frequency, if the whole network disposes the TD frequency of all sub-districts according to permanent order, the workload of setting is light relatively in configuration, but is easy to occur the situation that the frequency leakage of needs configuration is joined, and causes terminal can't detect suitable frequency, can not directly switch.If the whole network is according to analyzing respectively each sub-district, according to the suitable frequency of each cell configuration, the corresponding work amount is very big, and if the network neighboring BS relationship changes, also needs the frequency of adjacent sub-district is adjusted, and can further strengthen workload.
