In code division multiple access mobile communcations systems such as (CDMA), the whole process of travelling carriage access base station system probably needs about 1 second time.In this 1 second short time, rapid deterioration may take place in the radio condition between travelling carriage and the base station.For example, in the more big city of building, because shade or turning effect occupy advantage, the deterioration of radio condition is more frequent, usually can cause the travelling carriage access failure.
In order to address this problem, in mobile communication system, introduced the access handoff technique.According to inserting handoff technique, travelling carriage can switch when carrying out access attempts, switches to strong pilot tone sub-district from weak pilot tone sub-district, and continues follow-up call flow.Wherein, the sub-district before switching can be called as the cell-of-origin, and the sub-district after the switching can be called as Target cell.Insert the access success rate that handoff technique can improve travelling carriage greatly.
As shown in Figure 1, according to the different phase of travelling carriage at an access attempts, can be divided into three kinds of different switching modes with inserting to switch: access inlet switching (Access Entry Handoff), Access Probe switch (Access Probe Handoff) and insert and reply switching (Access Handoff).
The time of inserting inlet switching generation is to receive between common beep-page message (GPM) and the initiation page response at travelling carriage.Be meant specifically: travelling carriage is paged under the cell-of-origin, takes place to insert inlet this moment and switches, and travelling carriage sends page response under Target cell.
The time that Access Probe switches generation is in mobile station calling and has received to echo and answered between the message (BS0rder message).Be meant specifically: travelling carriage the cell-of-origin rise exhale after, send the access channel detection sequence to the base station, this moment Access Probe takes place and switch, travelling carriage sends the access channel detection sequence on Target cell, and receives the BSOrder message of base station on Target cell.
It is to receive between BSOrder message and the Extended Channel Assignment Message (ECAM message) at travelling carriage that the time of switching generation is replied in access.Be meant specifically: travelling carriage the cell-of-origin rise exhale after, on the cell-of-origin, received the BSOrder message of base station calling channel, taken place this moment to insert to switch, on Target cell, received the ECAM message of base station calling channel.
Because it is very short to insert switching time, generally also with regard to about 1 second, if test inserts and switches under conventional environment, promptly adopt common handoff testing method, the people is the base station power of lifting Target cell, reduce the transmitting power of cell-of-origin, add the reaction time of radio-frequency devices lifting power, in 1 second, can't cause to insert and switch.Therefore, it is uncontrollable to adopt common handoff testing method can cause access to switch, and can't collect related data, can't verify artificially whether the base station product can support to insert switching.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.
The present inventor finds that in research and experiment generation inserts the difficult point of switching and wins the time of adjusting cell power with regard to the time interval that is how to prolong between each message point.As long as between the travelling carriage access periods, have sufficient time to adjust the power of cell-of-origin, travelling carriage just can switch, and makes to insert to switch to have controllability and measurability.
Switch for inserting inlet, if travelling carriage is in the cell-of-origin standby, and receive the beep-page message of base station at paging time-slot (Slot) the A place of cell-of-origin, when receiving beep-page message, reduces travelling carriage the power of cell-of-origin so at once, the power of lifting Target cell, inlet takes place to insert and switches in travelling carriage during this period, and at paging time-slot Slot B place, travelling carriage sends page-response message on Target cell then.In this case, the time of adjustment power can obtain by changing big slot cycle.
Switch for Access Probe, the ECAM message that has response message by the base station structure, use the ECAM retransmission mechanism that ECAM message delay a period of time is sent, and cooperate to close the BSOrder message of base station, make travelling carriage after sending call message, do not sending the access channel detection sequence owing to receive BSOrder message, always till receiving ECAM, reduce the power of cell-of-origin in the meantime, produce Access Probe with this and switch the condition that takes place.
Switch for inserting response, the ECAM retransmission mechanism by the base station sends ECAM message delay a period of time, reduces the power of cell-of-origin between BSOrder and ECAM, produces to insert response and switch the condition that takes place.
