Abstract

The method comprises: UE measures neighboring cells, and when determining that the current term of neighboring cells meets the term for reading out the system information saved, it reads and saves the system information of neighboring cells. Using the term for reading system information to selectively read the system information of neighboring cells will not influence the load of UE. When UE changes cell, the destination cell system information has been already read and saved by UE, and the base station of serving cell has no need to provide the system information of neighboring cells for UE after interacting with the base station of destination cell so as to reduce the signaling processing time between different cells. The base station of serving cell has no need to carry the system information of destination cell in the switch command sent down to UE so as to reduce the load of signaling transmitted in air interface.

Embodiment
Among the present invention, UE measures adjacent sub-district, determine adjacent sub-district when precondition satisfies the system message reading conditions of storage, read and store the system message of corresponding adjacent sub-district.The UE that is arranged so that by the system message reading conditions need not to read the system message of all adjacent sub-districts, can the load of UE not impacted like this.
Fig. 1 shows among the present invention UE to carry out the sub-district and changes first kind of realization flow figure, and as shown in Figure 1, subscriber equipment carries out the sub-district and changes the specific implementation process of embodiment one and may further comprise the steps:
Step 101～step 102:UE communicates at Serving cell and network side, receives the measurement control messages from network side, and adjacent sub-district is measured.
Step 103～step 104:UE determines the measurement report report condition when the satisfied storage of precondition of adjacent sub-district, reports the measurement report of corresponding adjacent sub-district to network side.Described measurement report report condition is carried in network side in the measurement control messages that UE sends, and like this, UE just can store the measurement report report condition of receiving; The measurement report report condition also can be pre-configured among the UE, this pre-configured measurement report report condition can upgrading by follow-up UE and network side alternately, for example, the measurement report report condition of renewal is carried at network side in the measurement control messages that UE sends.After UE stores the measurement report report condition, determine certain adjacent sub-district when precondition satisfies the measurement report report condition, just report the measurement report of this neighbour sub-district to network side, therefore, UE can report the measurement report of a plurality of adjacent sub-districts to network side, and the precondition of working as of these adjacent sub-districts all satisfies the measurement report report condition.
Step 101～step 104 is identical with the existing processing of carrying out measurement report, therefore, does not repeat them here.
Step 105～step 106:UE determines the system message reading conditions when the satisfied storage of precondition of the adjacent sub-district of reporting measurement reports, reads and store the system message of adjacent sub-district.Described system message reading conditions is carried in network side in the measurement control messages that UE sends, and like this, UE just can store the system message reading conditions of receiving; The system message reading conditions also can be pre-configured among the UE, for example, solidify in advance and be stored among the UE, or UE start back network side provides the system message reading conditions to UE, this pre-configured system message reading conditions can upgrading by follow-up UE and network side alternately, for example, the system message reading conditions of renewal is carried at network side in the measurement control messages that UE sends.After UE stores the system message reading conditions, determine certain reporting measurement reports adjacent sub-district when precondition satisfies the system message reading conditions, just read and store the system message of this neighbour sub-district, therefore, the system message of the adjacent sub-district of a plurality of reporting measurement reports of UE storage, the precondition of working as of these adjacent sub-districts all satisfies the system message reading conditions.The system message reading conditions can be identical with the measurement report report condition, promptly identical with the existing condition that is provided with, for example, incident 1a: Primary Common Pilot Channel signal (Primary Common Pilot Channel, P-CPICH) enter reporting range (Reporting Range) (a Primary CPICH Enters the Reporting Range (FDD Only)), incident 1b:P-CPICH signal leaves reporting range (a Primary CPICH Leaves the Reporting Range (FDD Only)), incident 1c: non-activation P-CPICH signal is better than activating P-CPICH channel (a Non-active PrimaryCPICH Becomes Better Than an Active Primary CPICH (FDD Only)), incident 1d: Frequency Division Duplexing (FDD) (Frequency Division Duplex, FDD) change to the good sub-district of signal (Changeof Best Cell (FDD Only)) in the system, incident 1e:P-CPICH signal is better than absolute thresholding (a PrimaryCPICH Becomes Better Than an Absolute Threshold (FDD Only)), incident 1f:P-CPICH signal is inferior to absolute thresholding (a Primary CPICH Becomes Worse Than an AbsoluteThreshold (FDD Only)), incident 1g: time division duplex (Time Division Duplex, TDD) change to the good sub-district of signal (Change ofBest Cell in TDD) in the system, incident 1h: signal code power disturbs (Interference on Signal Code Power, ISCP) be lower than initial (Times Lot ISCP Belowa Certain Threshold (TDD Only)), incident 1i: signal code power disturbs and to be higher than initial (Times LotISCP Above a Certain Threshold (TDD Only)) etc., and the system message reading conditions can be the above one of them or combination arbitrarily; The system message reading conditions also can be different from the measurement report report condition, it is redefined, for example, incident 5a:P-CPICH signal enters the scope of fetching adjacent domain system message, incident 5b:P-CPICH signal leaves the scope of fetching adjacent domain system message, incident 5c:P-CPICH signal is higher than the P-CPICH of Serving cell, incident 5d:P-CPICH signal is higher than sets absolute thresholding, incident 5e:P-CPICH signal is lower than sets absolute thresholding etc., and the system message reading conditions can be the above one of them or combination arbitrarily; The system message reading conditions also can combine the condition that has setting now with the condition that redefines.The above scope is carried in network side in the measurement control messages that UE sends; Also can directly be configured among the UE, and can be further mutual by with network side, the scope of configuration is upgraded.Include cell ID and system message content in the system message.
Step 107～step 109: the measurement report that network side reports according to UE, to UE indicating target sub-district, UE and Target cell are synchronous, it is invalid that the system message of current service cell is set to, the system message of Target cell is set to current system message, the system message that is about to Target cell is set to effectively, UE with Target cell as Serving cell.
Fig. 2 shows among the present invention UE to carry out the sub-district and changes second kind of realization flow figure, and as shown in Figure 2, subscriber equipment carries out the sub-district and changes the specific implementation process of embodiment two and may further comprise the steps:
Step 201～step 202 is basic identical with step 101～step 102.
Step 203～step 204:UE determines that the precondition of working as of adjacent sub-district satisfies the system message reading conditions, reads and store the system message of corresponding adjacent sub-district.
Step 205～step 206:UE determines that the precondition of working as of the adjacent sub-district of read system message satisfies the measurement report report condition, reports the measurement report of respective cell to network side.
Step 207～step 209 is basic identical with step 107～step 109.
After the system message of UE Target cell was set to effectively, further the system message of other sub-districts of this UE storage was set to invalidly, also can directly delete.
After UE changes Serving cell, need once more to read adjacent sub-district be message the time, for the adjacent sub-district that stores system message, if the precondition of working as of corresponding adjacent sub-district satisfies the system message reading conditions, then UE can read the system message of adjacent sub-district again, also can only read that part of system message that changes.
