1, under actual conditions, has several different system cells around the sub-district, the current place of user terminal usually, thereby be difficult to determine suitable Target cell by the mode of blind switching;
2, the Target cell quality is not understood because of not measuring by the source system, and can't obtain user's particular location and moving direction, therefore when the registration of the coverage of sub-district, the current place of user terminal and the coverage of adjacent all different system cells when hanging down, handover success rate is lower between system.
Based on switching in the measuring process that has increased before the switching different system cell between the system of measuring, when satisfying certain condition, the signal strength signal intensity of different system cell or signal quality carry out switching between system.For this switching, because terminal need be measured another carrier frequency, therefore, do not possess in terminal under the situation of double-receiver condition, must support compact model, so that carry out measurement to another carrier frequency.Referring to flow chart shown in Figure 3, comprise: measure control stage, measurement report stage, switch decision stage, handover execution stage based on the canonical process that switches between the system of measuring.Measuring the control stage, the parameter that the control messages informing user terminal is measured is measured by sending by the source system; In the measurement report stage, user terminal sends measurement report message to the source system; In the switch decision stage, the source system makes switching judging according to measurement report; In handover execution stage, source system, destination system and user terminal are carried out signaling process, and make corresponding operating according to signaling.
Compare between system handover success rate with blind switching higher based on switching between the system of measuring, but the shortcoming of this mode is:
1, increased time delay for switching between system;
2, owing to will starting compact model when not possessing double-receiver, measures user terminal, and the measurement of compact model be because himself characteristics can cause the interference level of system to increase, and handover success rate, network capacity and quality of service are caused suitable influence.
