In the WCDMA system, subscriber equipment (UE) is when carrying out the sub-district switching, at first issue and comprise the concrete measuring amount of neighbor cell (as path loss by universal land radio access web (UTRAN), received signal power etc.) and report criterion (as regularly reporting, surpass or be lower than a certain thresholding and report) the measurement control messages give UE, UE measures the channel quality of this sub-district and neighbor cell simultaneously, when this cell channel degradation (being lower than the UTRAN specified thresholds), when the neighbor cell channel quality strengthens (surpassing the UTRAN specified thresholds), UE is by measuring reporting message to UTRAN reporting measurement result, decision is to upgrade the Active Set of UE or determine UE is switched to adjacent alien-frequency district to UTRAN according to measurement result, upgrade Active Set if desired, then UTRAN sends activating set updating message to UE, UE receives activating set updating message and according to the corresponding Active Set tabulation of these message additions and deletions, changes new sub-district simultaneously over to and then realize the soft handover of sub-district; Switch to adjacent alien-frequency district if desired, then UTRAN sends reconfiguration message (as the physical channel reconfiguration message) to UE, UE is after the activating set updating of receiving UTRAN or reconfiguration message, reconfigure Radio Link, and be sent completely message, and then finish whole cell switch process to UTRAN.
In above-mentioned UE cell switch process, need UE to finish the measurement of cell channel quality and reporting of measurement result, to produce the battery consumption of more UE like this, whether UE carries out the sub-district switching by UTRAN decision-making judgement simultaneously, judge by the decision-making of the radio network controller (RNC) of UTRAN promptly, reconfigure by UE then and implement to switch that it is longer that so not only UE carries out time of sub-district switching, and the decision-making of RNC is also very complicated, has caused the increase of RNC complexity and cost.
Summary of the invention
The object of the present invention is to provide a kind of cell switching method of cellular high speed gruping insertion network, UE adopt this method carry out the time that the sub-district switch to need few, efficient is high, and can reduce UE battery consumption, reduce the complexity of the RNC of Access Network.
For achieving the above object, the cell switching method based on cellular high speed gruping insertion network provided by the invention comprises:
A. subscriber equipment (UE) is measured the wireless base station, source (WIB) of internet protocol-based (IP agreement) and the channel quality of adjacent WIB, when the channel quality of adjacent WIB is better than the channel quality of source WIB, UE with adjacent WIB as target WIB, read the information of its broadcasting, therefrom obtain sign (W-ID) and the colour coding of target WIB;
B.UE is according to the protocol stack and the physical layer of the common signal channel parameter configuration self of target WIB broadcasting, and to target WIB initiation connection request, the former UE temporary mark (UTI that comprises UE in the described request, UETemporary Identifier), described UTI comprises the bit that is used to distinguish the colour coding of WIB and is used to distinguish UE;
C. target WIB obtains original session configuration of this UE according to the former UTI of UE;
D. target WIB is that UE distributes new UTI, and described UTI comprises the bit that is used to distinguish the colour coding of WIB and is used to distinguish UE; Simultaneously, target WIB is the UE distributing radio resource, sets up new communication link and discharges original communication link, thereby being connected between UE and the Access Network switched among the new WIB.
Step c realizes by following step:
A1) target WIB finds out the bit that source WIB identifies according to self colour coding, subnet mapping table, the bit combination that is used to identify UE with the UTI back obtains the former UTI of whole IP address designations of this UE, the UTI of the former UE of these whole IP address designations is issued target radio network controller (RNC-IP) based on the IP agreement, original session configuration of this UE of request inquiry, whether to one's name Target RNC-IP judges source WIB control according to the former UTI of UE, if change steps A 2), otherwise change steps A 3);
A2) Target RNC-IP issues source WIB with the UTI of the former UE of whole IP address designations, original session configuration that source WIB feeds back this UE to Target RNC-IP, and RNC-IP issues target WIB with original session configuration of above-mentioned UE, finishes then;
A3) Target RNC-IP issues source RNC-IP with the UTI of the former UE of whole IP address designations, source RNC-IP is forwarded to source WIB with the UTI of above-mentioned former UE again, source WIB feeds back original session configuration of this UE to source RNC-IP, source RNC-IP is transmitted to Target RNC-IP with original session configuration of above-mentioned UE, Target RNC-IP is transmitted to target WIB with original session configuration of above-mentioned UE again, finishes then.
When source WIB and target WIB belong to a RNC-IP control, the communication link that the described foundation of steps d is new also discharges original communication link and is: set up Radio Link between target WIB and UE, and set up terrestrial links between target WIB and the RNC-IP, discharge terrestrial links between RNC-IP and the source WIB and the airlink between source of release WIB and the UE simultaneously.
When source WIB and target WIB do not belong to a RNC-IP control, the communication link that the described foundation of steps d is new also discharges original communication link and is: set up Radio Link between target WIB and UE, between target WIB and Target RNC-IP, set up terrestrial links, and between Target RNC-IP and Serving GPRS Support Node (SGSN), set up link, terrestrial links between the link between while source of release RNC-IP and the SGSN, release RNC-IP and the source WIB and the airlink between source of release WIB and the UE.
Because the present invention is in soft switching process, UE sends to target WIB with original UTI, target WIB learns according to its colour coding this UE from which WIB switches, thereby obtain the session configuration information from source WIB, target WIB reconfigures Radio Link on this basis, discharge assigned radio resource in the last sub-district again, newly set up a connection, simplified the parameter configuration process greatly with respect to UE.Compare with existing method,, can reduce battery consumption, RNC-IP need not be made decision to all measurements of UE, its complexity is reduced greatly, help product cost and reduce because the present invention does not need the frequent reporting measurement result of UE; Simultaneously, report decision process with RNC-IP owing to save the UE measurement, whole handoff procedure institute time-consuming significantly reduces, therefore, the time that employing the method for the invention is carried out sub-district switching needs is few, efficient is high, can reduce the battery consumption of UE and the complexity that reduces the RNC-IP of Access Network.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
At first with reference to figure 2, Fig. 2 is the CHPA wireless accessing network structure figure of application drawing 1 described method.Among Fig. 2, radio network controller (RNC-IP) is the radio network controller of internet protocol-based (IP agreement), base station (WIB, Wireless Internet BaseStation) be base station based on the Internet, different RNC-IP connects by interface Iur, RNC-IP is connected by interface Iub with WIB, is connected by interface Uu between WIB and the UE.RNC-IP, WIB, have with this WIB and to be tree-shaped relation between the UE that is connected.
In network shown in Figure 2, in order to support IP-based mobile UE better, with the 6th edition IP (IPv6) address compatibility, the RNC-IP in the CHPA Access Network, WIB and UE all are provided with the IP address designation of 128 (bit).Wherein RNC-IP and WIB are the static address sign, are set when laying network by operator.When WIB and UE set up session each time, WIB was temporary mark UTI of UE dynamic assignment (UE Temporary Identifier), so as in this WIB unique identification UE and and this UE between this session.When the IP address designation RNC-IP, the WIB that adopt 128bit and UE, the IP address of 128bit is divided into three sections, preceding M1bit is first section, is used to identify RNC-IP; The M2bit at middle part is second section, is used to identify the WIB under the RNC-IP, promptly adds that with preceding M1bit M2bit identifies the WIB under the RNC-IP; The M3bit at rear portion is the 3rd section, is used to identify the UE under the WIB, promptly adds M2bit with preceding M1bit, adds the UE under the M3bit sign WIB.In Fig. 2, M1 is 80bit, and M2 is 24bit, and M3 is 24bit, with reference to figure 4.
Therefore, in network shown in Figure 2, a WIB is corresponding one by one with an IPv6 subnet.Because the UE of WIB and its distribution UTI is in same subnet, WIB and these UE sign preceding 104 identical, WIB and these UE are WIB subsystem of formation jointly.And adjacent WIB preceding 104 all inequality.In addition, for the WIB of same RNC-IP control, its preceding 80bit is identical.These WIB and distribute the UE of UTI by these WIB, all identical with 80bit before the sign of this RNC-IP, they constitute a RNC-IP subsystem jointly.Therefore in Fig. 2,80bit is different before the different RNC-IP, and the identical WIB of preceding 80bit belongs to same RNC-IP control.Its preceding 104bit of different WIB is different, and its UTI of UE that connects with same WIB is by this WIB dynamic assignment, and the preceding 104bit of these UE is identical with this WIB.
Based on Fig. 2, when the described method of Fig. 1 is specifically implemented, in order to save air resource, avoid transmitting the UTI of 128bit aloft, by the preceding 104bit of colour coding with the WIB sign, promptly be used to distinguish the colour coding of the preceding 104bit boil down to 8bit of WIB, and definite WIB is identified to the mapping relations between the colour coding, this relation can be set at the beginning of networking in operator, and these mapping relations are left among each WIB, promptly in each WIB, deposit between colour coding and the adjacent WIB one, the subnet mapping table of one correspondence makes WIB comprise self 128bitIP address designation W-ID and colour coding simultaneously in the information of broadcasting.Like this, as long as adjacent WIB has different colour codings arbitrarily, identical colour coding can be reused after being spaced a distance, and the situation of corresponding two the adjacent WIB of a colour coding can not occur.WIB can obtain the preceding 104bit of a unique adjacent WIB sign according to colour coding simultaneously.
Based on aforesaid operations, after UE and WIB connect, the UTI that needn't use 128bit alternately each other, but directly use the back 24bit of 128bitIP address designation.By the 128bitIP address designation W-ID and the colour coding of WIB broadcasting self, when UE moved into another WIB, 104bit and colour coding were different with self colour coding before UE can detect, and UE knows and enters another WIB thus, needs enforcement relay soft switching process.
Fig. 3 describes a kind of mapping between WIB and the colour coding.As can be seen from Figure 3, WIB8 and WIB6 use identical colour coding, i.e. colour coding CC=6, because the segment distance of being separated by between them, thereby the adjacent WIB1 of WIB6 can distinguish it by colour coding.
Fig. 1 is the embodiment flow chart of the method for the invention.According to Fig. 1, when initial, UE and source WIB have set up one and have been connected and keep this connection, and source WIB is the interim UTI (UE temporary mark) that UE has distributed a 128bit, and the back 24bit that passes through UTI like this between UE and the source WIB alternately gets final product.In the UE moving process, at the channel quality of step 1UE measurement source WIB and adjacent WIB, the detection of channel quality is undertaken by the pilot signal that detects source WIB, target WIB.When the channel quality of adjacent WIB was better than the channel quality of source WIB, UE as target WIB, read the broadcast message of this target WIB with adjacent WIB, thereby obtained W-ID and the colour coding of target WIB.According to colour coding, UE knew and entered new WIB this moment.UE disposes self protocol stack and physical layer in step 2 according to the common signal channel parameter (Physical Random Access Channel/Random Access Channel PRACH/RACH, physical access channel FPACH, S-CCPCH Secondary Common Control Physical Channel/forward access channel SCCPCH/FACH) that target WIB broadcasts then, and to target WIB initiation connection request RADIO ACCESSREQUEST message, carried the former UTI of UE in this message, described UTI comprises the bit that is used to distinguish the colour coding of WIB and is used to distinguish UE, i.e. 32 former UTI (comprising 8 colour codings and 24 last bits).Target WIB is by preceding 8 colour codings among the contrast UE former UTI, finds differently with self colour coding, knows that promptly this UE is from adjacent WIB switching.
Target WIB is in order to obtain original session configuration of UE and source WIB, the former UTI of UE is sent to the Target RNC-IP of own correspondence in step 3, give target WIB by original session configuration concurrency that Target RNC-IP obtains UE in step 4, ideal WIB distributes new UTI in step 5 for UE, and described UTI comprises the bit that is used to distinguish the colour coding of WIB and is used to distinguish UE; Be that target WIB distributes 32 new UTI to UE, preceding 8bit is target WIB self colour coding, and back 24bit is the unique temporary identity of current UE in target WIB; Simultaneously, target WIB is the UE distributing radio resource, sets up new communication link and discharges original communication link, thereby being connected between UE and the Access Network switched among the new WIB.
The following process of the realization of above-mentioned steps 3,4 reference in this example: at first target WIB is according to preceding 8 colour codings among the former UTI of UE, and according to self colour coding, the subnet mapping table finds out source WIB sign bit, 104bit promptly, be used to identify the bit of UE with the UTI back, be the UTI that the back 24bit combination of UTI obtains the former UE of whole IP address designations, the i.e. former UTI of the 128bit of UE.Target WIB can judge source WIB and self belong to a RNC-IP control according to the preceding 80bit of WIB sign this moment.Then target WIB issues Target RNC-IP, the request inquiry original session configuration of this UE (as L2 configuration, RAB configuration etc.) with 128 former UTI.Whether to one's name Target RNC-IP judges source WIB control according to the preceding 80bit of UTI, if control to one's name then according to preceding 104bit, is mail to source WIB with the former UTI of UE, request source WIB feeds back the session configuration information of this UTI.Source WIB disposes to original session that Target RNC-IP returns this UE, and Target RNC-IP issues target WIB with this session configuration then.If source WIB is control to one's name not, then Target RNC-IP needs further clear and definite source RNC-IP, and according to the preceding 80bit of the former UTI of UE, Target RNC-IP mails to source RNC-IP with the former UTI of UE, source RNC-IP goes to source WIB with the former UTI of UE again, and request source WIB feeds back the session configuration information of this UTI.Source WIB disposes to original session that source RNC-IP returns this UE, and source RNC-IP hands to Target RNC-IP with original session configuration of UE, by Target RNC-IP target WIB is issued in this session configuration.
Above-mentioned steps 5 described target WIB are the UE distributing radio resource in this example, the realization of setting up new communication link and discharging original communication link is with reference to following process: when source WIB and target WIB belong to same RNC-IP control, target WIB is the UE distributing radio resource, set up Radio Link, set up terrestrial links between target WIB and the RNC-IP simultaneously, terrestrial links resource between release RNC-IP and the source WIB and the air link resources between source of release WIB and the UE.
When source WIB and target WIB did not belong to same RNC-IP control, target WIB was the UE distributing radio resource, sets up Radio Link, sets up between target WIB and the RNC-IP between terrestrial links and Target RNC-IP and the SGSN and sets up link; Discharge link between RNC-IP and the SGSN simultaneously, discharge the terrestrial links resource between RNC-IP and the source WIB, and the air link resources between source of release WIB and the UE.
