Abstract
The invention discloses cell switching methods and equipment. According to one cell switching method, a switching command that is sent by a radio network controller (RNC) to a terminal is expanded and thus the switching command not only carries an uplink physical channel (UpPCH) position information of a target cell main frequency point but also carries UpPCH position information of a target cell auxiliary frequency point, so that the UpPCH positions of the main frequency point and the auxiliary frequency point are different; and under circumstances that the target cell uses high speed uplink packet access (HSUPA) resources of the auxiliary frequency point, the terminal carries out uplink synchronization respectively at the main frequency point and the auxiliary frequency point. Meanwhile, according to the other method, UpPCH positions of a main frequency point and an auxiliary frequency point are adjusted into a same position; and under circumstances that a current switching command is not changed, UpPCH position information carried in the switching command is used to express the UpPCH position of the main frequency point and the UpPCH position of the auxiliary frequency point; and moreover, it is ensured that UpPCH interference of the main frequency point and the auxiliary frequency point at the UpPCH position are in a certain range, so that the terminal carries out uplink synchronization respectively at the main frequency point and the auxiliary frequency point. According to the invention, it can be avoided that uplink synchronization fails after HSUPA switching.
Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of cell switching method and equipment thereof.
Background technology
HSUPA (High Speed Uplink Packet Access; High Speed Uplink Packet inserts) when the terminal switches to Target cell and has distributed the resource of the auxilliary frequency of HSUPA; Two kinds of methods of synchronization are arranged at present: mode one; The common uplink synchronous and the uplink synchronous of enhancing are carried out simultaneously at the auxilliary frequency of HSUPA in the HSUPA terminal, but see that from the result of practical application most of manufacturer terminal is not supported this method of synchronization; Mode two, common uplink synchronous is carried out at the dominant frequency point in the HSUPA terminal, and in the uplink synchronous that the auxilliary frequency of HSUPA strengthens, this is a kind of method of synchronization that present manufacturer terminal generally adopts.
Network side is issuing switching command to the user; Like PhyCH (Physical Channel; Physical channel) reconfigure command or TrCH (Transport Channel; Transmission channel) reconfigure command or RB (Radio Bear; Radio bearer) during reconfigure command, FPACH (Fast Physical Access Channel, physical access channel) the info IE (information unit) among the Uplink Timing Advance Control (going up line time controls in advance) extends this as FPACH (the Fast Physical Access Channel that is used for common access on the Target cell dominant frequency point; Physical access channel) resource information; FPACH info among E-RUCCH (E-DCH (Enhanced Dedicated Channel strengthens dedicated channel) inserts ascending control channel at random) the Info IE extends this as the FPACH resource information that is used to strengthen access on Target cell UE (User Equipment, the terminal) working frequency points; UpPCH Position Info (UpPCH positional information among the Multi-frequency Info (multi-frequency information); Wherein, UpPCH is that the English of Uplink Physical Channel is write a Chinese character in simplified form, and Chinese translation is a uplink physical channel) be the UpPCH position of dominant frequency point or working frequency points.
Because the UpPCH position that the UpPCH Position Info among the Multi-frequency Info can only carry a frequency, when the UpPCH position of the UpPCH position of dominant frequency point and auxilliary frequency is inconsistent, if carry the UpPCH position of dominant frequency point here; So can handover success; When but the professional up enhancing of HSUPA is synchronous,, may fail because that the user carries out up enhancing with reference to the UpPCH position of dominant frequency point is synchronous; Cause switching the up no speed in back, influence user's perception; If carry the UpPCH position of working frequency points here, common uplink synchronous can't be accomplished in the terminal when switching so, cause handoff failure, increase cutting off rate.
It is thus clear that call drop takes place or switches the no speed in back in the HSUPA that adopts the above-mentioned method of synchronization possibly cause the HSUPA terminal to switch to Target cell when assisting carrier wave, have a strong impact on handover success rate and user's perception.
Present a solution is: close the algorithm of UpPCH adjustment, promptly the UpPCH position of dominant frequency point and working frequency points is consistent, and the mode of static configuration is adopted in the UpPCH position.
Though this scheme can be evaded the deficiency of the above-mentioned method of synchronization; The disturbed condition of up UpPCH position was to change at any time during but real network was used; If can not in time adjust the UpPCH position, possibly cause the user to make a call because disturb too big, have a strong impact on call completing rate.Even in addition with UpPCH position initial configuration a position (after generally all being 0 position) that interference is relatively little, this also can increase the interference of uplink service time slot, can be influential to power system capacity.

Embodiment one
Can know according to aforementioned description prior art; The method of synchronization that existing HSUPA terminal switches to behind the Target cell causes the basic reason that up no speed is perhaps switched call drop to be: the UpPCH Position Info among the Multi-frequency Info can only carry the UpPCH position of a frequency, therefore only allows to fill in the UpPCH position of dominant frequency point or the UpPCH position of the auxilliary frequency of HSUPA.If not only having known the UpPCH position (being the UpPCH position of dominant frequency point) that is used for common uplink synchronous but also known, the terminal was used for the synchronous UpPCH position of enhanced uplink (being the UpPCH position of the auxilliary frequency of HSUPA), then head it off at all.
According to above analysis; Present embodiment proposes: in network side sends to the switching command at terminal, increase IE (information unit); Carry the UpPCH position of HSUPA enhanced uplink when synchronous, like this, the terminal just can not only have been known the UpPCH position that is used for common uplink synchronous but also know and had been used for the synchronous UpPCH position of enhanced uplink through this switching command; Thereby at dominant frequency point with to assist the UpPCH position of frequency inconsistent; And use at Target cell under the situation of the HSUPA resource of assisting frequency, carry out common uplink synchronous, assist the uplink synchronous that frequency strengthens at HSUPA at the dominant frequency point.Said switching command includes but not limited to PhyCH reconfigure command or TrCH reconfigure command or RB reconfigure command.
During practical implementation; Can be at the E-RUCCH of switching command Info (TDD only; Promptly only be used for the TDD system) UpPCH Position Info IE of increase; This IE is used to carry the UpPCH position of HSUPA enhanced uplink when synchronous, and the UpPCH position during the common uplink synchronous of HSUPA is carried by the UpPCH Position Info IE among original Multi-frequency Info IE in the switching command.Certainly, the UpPCH position when this newly-increased IE also can be used for carrying the common uplink synchronous of HSUPA, corresponding, the UpPCH Position Info IE among the Multi-frequency Info IE carries the UpPCH position of HSUPA enhanced uplink when synchronous.

To adopt TD-SCDMA (the Time Division-Synchronous Code Division Multiple Access of HSUPA; TD SDMA) system is an example; Fig. 1 shows a kind of HSUPA switching flow sketch map that the embodiment of the invention provides; As shown in the figure, this flow process can comprise:
During practical implementation, this switching command can be PhyCH reconfigure command (like the channel variation between UE and base station time) or TrCH reconfigure command (like the channel variation between UE and RNC time) or RB reconfigure command (like the channel variation between RNC and core net time).
In the switching command in the embodiment of the invention; FPACH info IE among the Uplink Timing Advance Control extends this as the FPACH resource information that is used for common access on the Target cell dominant frequency point; UpPCH Position Info among the Multi-frequency Info extends this as the UpPCH position of dominant frequency point; FPACH info among the E-RUCCH Info IE extends this as the FPACH resource information that is used to strengthen access on the auxilliary frequency of Target cell HSUPA, and the UpPCH Position Info IE among the E-RUCCH Info IE extends this as the UpPCH position of the auxilliary frequency of HSUPA.Wherein, the UpPCH position of the auxilliary frequency of the UpPCH position of dominant frequency point and HSUPA can be the same or different.
Concrete; UE carries out common uplink synchronous according to the FPACH resource information that is used for common access on the UpPCH position of Target cell dominant frequency point and the Target cell dominant frequency point at the dominant frequency point, and the FPACH resource information that is used to strengthen access on the auxilliary frequency of UpPCH position and Target cell HSUPA according to the auxilliary frequency of Target cell HSUPA is assisted the uplink synchronous that frequency strengthens at HSUPA.
Can find out through above description; The present invention implements to have solved the problem that existing HSUPA terminal switches to the method for synchronization existence behind the Target cell through agreement upgrading (promptly in switching command, increasing information unit); And do not influence UpPTS (Up link Pilot TimeSlot; Uplink pilot time slot) algorithm itself (can independently carry out by the UpPCH position adjustment of the auxilliary frequency of dominant frequency point and HSUPA; And adjust according to disturbed condition in good time), avoid exhaling failure or inserting the excessive problem of back uplink service time slot interference because the interference of UpPCH position causes the user to rise.
Embodiment two
Present embodiment is under the prerequisite of the existing protocol of not upgrading; In conjunction with disturbed condition the UpPCH position is adjusted in good time; And the UpPCH position that guarantees auxilliary frequency of HSUPA and dominant frequency point is identical; Like this, through the UpPCH positional information (dominant frequency point is identical with the UpPCH position of assisting frequency) that existing switching command carries dominant frequency point or the auxilliary frequency of HSUPA, UE can be according to this UpPCH position of Target cell dominant frequency point and the auxilliary frequency of HSUPA; And the FPACH resource information that is used to strengthen access on the auxilliary frequency of the FPACH resource information and the Target cell HSUPA that are used for common access on the Target cell dominant frequency point, carry out uplink synchronous.
Referring to Fig. 2, be a kind of HSUPA switching flow sketch map that the embodiment of the invention two provides, this flow process can comprise:
Step 201; RNC receives behind the measurement report of UE decision to carry out the sub-district to this UE and switches; So send switching command to this UE; Wherein carry the UpPCH positional information (dominant frequency point is identical with the uplink synchronous UpPCH position of assisting frequency) that is used for uplink synchronous, on this UpPCH position, the dominant frequency point and the interference of assisting frequency are all less than setting threshold.This switching command can be the PhyCH reconfigure command, or the TrCH reconfigure command, or the RB reconfigure command.
In the specific implementation, the operation of confirming the UpPCH position can be realized by the corresponding function module among the RNC (like the UpPTS algoritic module).Preferably; This module has enable switch, and under the situation that the algorithm function of this module enables, the hand-off process module among the RNC is carried on switching command with the UpPCH positional information that the UpPTS algoritic module calculates; In such cases; The UpPCH position that this UpPCH position is a dominant frequency point is again the UpPCH position of auxilliary frequency, and on this UpPCH position, and the dominant frequency point and the interference of assisting frequency are all less than setting threshold.
In the specific implementation; But the UpPCH disturbed condition of the auxilliary frequency of UpPTS algoritic module monitoring objective sub-district dominant frequency point among the RNC and HSUPA; If the UpPCH of one of them frequency disturbs greater than setting thresholding; Then adjust the UpPCH position of the auxilliary frequency of dominant frequency point and HSUPA, adjusted target UpPCH position should guarantee that dominant frequency point and HSUPA assist interference on the frequency all less than the setting thresholding.
The UpPCH position is usually used since 0 numbering that also increases progressively gradually and is carried out index.During embodiment of the invention practical implementation; UpPTS algoritic module among the RNC can be judged the UpPCH disturbed condition of locational dominant frequency point of the current UpPCH of UE and the auxilliary frequency of HSUPA earlier; If wherein there is the UpPCH of a frequency to disturb greater than setting thresholding; Then from this UpPCH position forward (direction that promptly reduces) towards the UpPCH Position Number or/and backward (direction that promptly increases) towards the UpPCH Position Number search other satisfy above-mentioned disturbed condition (be dominant frequency point with assist frequency in the locational UpPCH interference of identical UpPCH all less than setting threshold) the UpPCH position; In case find the UpPCH position of satisfying interference requirement; This position is adjusted in the UpPCH position that is about to the auxilliary frequency of dominant frequency point and HSUPA, and corresponding, the UpPCH positional information of carrying in the switching command is the adjusted UpPCH positional information of UpPTS algoritic module.
Step 202, UE carries out the sub-district according to the switching command that receives and switches, and cell switch process can adopt current mechanism to realize, does not give unnecessary details at this.
Step 203 is after UE switches to Target cell, according to the information of carrying in the switching command that receives, at Target cell dominant frequency point with assist and carry out uplink synchronous on the frequency.
Concrete; UE carries out common uplink synchronous according to the FPACH resource information that is used for common access on UpPCH position of carrying in the switching command and the Target cell dominant frequency point at the dominant frequency point, the uplink synchronous that strengthens at the auxilliary frequency of HSUPA according to the FPACH resource information that is used to strengthen access on the auxilliary frequency of the UpPCH position of carrying in the switching command and Target cell HSUPA.
The UpPCH position of satisfying disturbed condition may exist a plurality of.To this situation, in another embodiment of the present invention, the UpPTS algoritic module among the RNC can be selected the UpPCH position littler than the interference of current UpPCH position.During concrete the realization; RNC is after finding the UpPCH position (convenient for describing, as to be called UpPCH position A here) that meets disturbed condition, if found before current UpPCH position; Also exist a UpPCH position (convenient for describing; Be called UpPCH position B here), the interference of the auxilliary frequency of dominant frequency point on the B of UpPCH position and HSUPA is all less than the interference on the A of UpPCH position, and then the UpPCH position with dominant frequency point and the auxilliary frequency of HSUPA is adjusted into UpPCH position B.Preferably, relative interference threshold can be set in advance, if UpPCH position B meets the following conditions:
Disturb < interference threshold-interference relative threshold
The UPPCH position of then adjusting the auxilliary frequency of dominant frequency point and HSUPA is to UpPCH position B.
Can find out that through above description the embodiment of the invention two can be improved through the RNC algorithm, at utmost considers the dynamic adjustment of UpPCH position, the drawback of avoiding UpPCH position static configuration to introduce under the prerequisite that does not need upgrading terminals.
