Certainly; Those skilled in the art it will also be appreciated that the mode that other select soft-handoff parameters; For example: the selection mode that will as above mention makes up, and uses the mode of selecting through reference pilot having under the situation of reference pilot, does not have under the situation of reference pilot to use other arbitrary modes; Use above-mentioned a plurality of selection mode simultaneously, the soft-handoff parameters of selecting is respectively carried out weighted sum by the predefined weight coefficient obtain the soft-handoff parameters that is used to upgrade; Use above-mentioned a plurality of selection mode simultaneously, each component in the soft-handoff parameters of selecting is respectively averaged obtains the soft-handoff parameters that is used to upgrade; When the pilot tone number a predetermined level is exceeded that reports, select to have the peaked soft-handoff parameters of PilotAdd; When the difference of the pilot signal strength that reports is lower than predetermined value, select to have peaked soft-handoff parameters of PilotCompare or the like.And those skilled in the art it will also be appreciated that soft-handoff parameters can comprise different components, and can specify different components to assist the selection of carrying out soft-handoff parameters.

Especially; When accessing terminal 150 when being in special overlay area; Because the pilot tone in the special overlay area is provided with special soft-handoff parameters in advance; According to the selected soft-handoff parameters of predetermined selection mode normally with special overlay area in the corresponding soft-handoff parameters of certain pilot tone, can be adapted to current network environment more.For example, make according to the predetermined selected soft-handoff parameters of selection mode access terminal in the service that can be stabilized in a plurality of pilot tones, do not have the pilot tone that gets into and withdraw from Active Set repeatedly, the pilot tone that can use own preference of accessing terminal, access terminal get rid of with disturb pilot tone to add in the Active Set, accessing terminal has the pilot tone that satisfies certain intensity can use etc. all the time.

Through the selection to soft-handoff parameters, access network equipment can be confirmed suitable soft-handoff parameters according to pilot frequency information, by means of selected soft-handoff parameters, can carry out soft handover smoothly, improves the telecommunication service quality in the soft switching process.

In S260,150 send the parameter update message carry selected soft-handoff parameters to accessing terminal.

After access network equipment 100 has been selected soft-handoff parameters, it is included in to send in the parameter update message accesses terminal 150, letting accesses terminal 150 carries out parameter update according to entrained soft-handoff parameters, in time adjusts the reporting information of assist in soft handover process.

Method according to the renewal soft-handoff parameters of the embodiment of the invention; The pilot frequency information that carries in the update inquiry information that access network equipment can report according to accessing terminal is selected soft-handoff parameters; And send to access terminal and let it upgrade, change with the soft-handoff parameters that is implemented in the soft switching process.This not only makes to access terminal and can adapt to current network environment, in time adjusts the reporting information of assist in soft handover process, also successfully accomplishes soft handover fast, and because soft-handoff parameters is more reasonable, has improved the telecommunication service quality in the soft switching process.Particularly under the situation of special overlay area,, make the user who is in the special overlay area can in soft switching process, enjoy the excellent communications service equally owing to can special soft-handoff parameters be set in advance to the special networks environment.

Fig. 3 is the flow chart according to another method 300 of the renewal soft-handoff parameters of being carried out by access network equipment of the embodiment of the invention.Than the method 200 of the renewal soft-handoff parameters of Fig. 2, the S320 among Fig. 3, S340 and S360 respectively with Fig. 2 in S220, S240 and S260 basic identical, therefore repeat no more.Fig. 3 also comprised S350 before S360 sends the parameter update message of carrying selected soft-handoff parameters to accessing terminal, judge whether that according to update inquiry information needs upgrade soft-handoff parameters.
