In the embodiment of the invention, when terminal is carried out the alien frequencies direct-cut operation, adopt regularly reconstruction mode, that is to say, need between second terminal and RNC (Radio Network Controller, radio network controller), redistribute DOFF (DPCH Offset Value, the DPCH deviant), so that second terminal is determined CFN, described CFN is used for the synchronous of terminal and UTRAN (Universal Terrestrial Radio Access, global terrestrial radio inserts) transmission channel.Therefore, above-mentioned first synchronization parameter can be that network side is the DOFF that first alien-frequency district in second terminal and the above-mentioned a plurality of alien-frequency district connects and distributes, and is designated as DOFF2.
Correspondingly, second terminal can obtain CFN and DPCH vertical shift according to the value of above-mentioned DOFF2, for convenience, the CFN of second terminal is designated as CFN2, and concrete formula is as follows:
CFN2=(SFN1-((DOFF2*512)/38400))MOD?256 (1)
DPCH vertical shift=ROUND (((DOFF2*512) MOD 38400)/256 (2)
Wherein, SFN1 is the sub-district frame number of above-mentioned first alien-frequency district, second terminal can use main scrambler that P-CCPCH (Primary Common Control Physical Channel, Primary Common Control Physical Channel) is decoded, and obtains the sub-district frame number of first alien-frequency district.

OFF+Tm=(SFN2-CFN1)MOD?256 (4)
Owing to there is not the synchronizing information of its first alien-frequency district that comprises and second alien-frequency district in the different-frequency measure reporting of second terminal to report, therefore, network side can pass through the synchronizing information of first terminal to report of record, determine the required synchronization parameter that connects between second terminal and second alien-frequency district, be second synchronization parameter above-mentioned, concrete computational process is as follows:
Can obtain by above-mentioned formula (4):
CFN1=(SFN2-OFF)MOD?256 (5)
Suppose that OFF1 and Tm1 are first terminal OFF and the Tm value corresponding with the synchronized relation SFN2-CFN1 of second alien-frequency district of first terminal to report, then can be obtained by above-mentioned formula (3) and (5):
(SFN1-((DOFF1*512)/38400))MOD?256=(SFN2-OFF1)MOD?256 (6)
Can obtain by above-mentioned formula (1) and (5):
(SFN1-((DOFF2*512)/38400))MOD?256=(SFN2-OFF2)MOD?256 (7)
Wherein, OFF2 is second terminal OFF value corresponding with the synchronized relation SFN2-CFN2 of second alien-frequency district that second terminal should report.

For another example, comprise three alien-frequency districts in the different-frequency measure reporting that second terminal UE 2 reports, be respectively C1, C2, C3.
First terminal UE 1 inserts in C1, the CFN1 that connects, and when soft handover, increased C2, then UE1 can report OFF corresponding with the synchronized relation SFN2-CFN1 of C2 and Tm value.
The 3rd terminal UE 3 inserts in C1, the CFN3 that connects, and when soft handover, increased C3, then UE3 can report OFF corresponding with the synchronized relation SFN3-CFN3 of C3 and Tm value.
Like this, the OFF and the Tm value of the SFN2-CFN1 correspondence that network side can report according to UE1 calculate second terminal UE 2 OFF corresponding with the synchronized relation SFN2-CFN2 of C2, and the Tm value of the SFN2-CFN1 correspondence that UE1 is reported is as the Tm value of SFN2-CFN2 correspondence, and OFF and the Tm value with the SFN2-CFN2 correspondence is handed down to C2 and UE2 respectively then.Simultaneously, the OFF and the Tm value of the SFN3-CFN3 correspondence that network side also reports according to UE3 calculate second terminal UE 2 OFF corresponding with the synchronized relation SFN3-CFN3 of C3, and the Tm value of the SFN3-CFN3 correspondence that UE3 is reported is as the Tm value of SFN3-CFN2 correspondence, and OFF and the Tm value with the SFN3-CFN2 correspondence is handed down to C3 and UE2 respectively then.
