Description
Technical field
The present invention relates to the switching controls technology in cellular mobile communication field, more precisely, relate to the switching controls technology in the TDD/CDMA cell mobile communication systems of the multifrequency point that disposes shared common signal channel.
Background technology
In order to satisfy the ever-increasing demand of mobile subscriber in the Digital Cellular System of future generation, use sectorization and multi-transceiver technology can reduce system in and disturb, and thereby the capacity of increase system.The major advantage of cell sectorization is to have suppressed intersymbol interference, compare with the sub-district of non-sectorization, under the identical condition of number of users, the cell communication quality of sectorization will get a promotion, perhaps under the situation of keeping same systematic function, sectorization can increase the number of users that the sub-district holds.
When a base station of containing a plurality of frequencies covers 3 sectors, present way generally is to regard each carrier wave in three sectors of each sub-district as independently logic district, in RRM (RRM) algorithm system one to one/resource on three carrier waves in a plurality of sectors distributes and manages.For example, for the situation of three sectors, three carrier frequency, then thinking has 9 logic district, finishes independently operation at each sub-district.Also be that 9 sub-districts send pilot tone and broadcast message separately.Therefore, in this case, each carrier wave all must configuration one overlap complete common signal channel, and wherein broadcast channel (BCH), forward access channel (FACH) and paging channel (PCH) are omnidirectional channel.Like this, Multi-Carrier basestation not only requires very high when actual networking to transmitter power, and under the situation of identical networking, the interference of intercarrier broadcast channel is also very serious.The resource utilization of simultaneity factor is also lower.In order to address these problems, proposed for the time-division synchronously-code division multiple access (TD-SCDMA) system, can only on a carrier frequency of sector, send pilot tone and broadcast message, and other frequency only provides Traffic Channel.For only disposing common signal channel and other auxilliary frequency TD-SCDMA system as Traffic Channel at dominant frequency point, its changing method with each carrier wave in a plurality of sectors of each sub-district is regarded independently as logic district in employed changing method compare, bigger difference is arranged.Wherein the latter can use the handoff algorithms identical with single carrier frequency system.At present, switching for single carrier frequency system, general user's equipment (UE) is measured adjacent sub-district according to measuring control information and is reported, radio network controller (RNC) is adjudicated according to measurement result, and select target sub-district, notice UE carries out and switches, and there is not the problem that a plurality of frequencies are arranged in Target cell or the target logic sub-district in all these processes.
Existing time-division duplex (TDD/CDMA) changing method that mobile communication system adopted all be based on each contained fan as one independently logic district carry out, its measurement, judgement, admittance control and execution all are the protocol procedures of standard, and these methods are feasible, effective for single carrier frequency system and satisfy the demands.But, TDD/CDMA system for a plurality of carrier waves of configuration and common broadcast and common channel, owing to only on a carrier frequency of sector, send pilot tone and broadcast message, and other frequency only provides Traffic Channel, therefore, measuring process, judging process, admittance process and the last implementation switched are very different, and the method for handover control of originally single carrier cell can not be suitable fully.For example, in multi-carrier frequency system, the user both can be operated on the main carrier of target logic sub-district when switching, and also can be operated on the subcarrier, and the user in single carrier frequency system can only be operated in when switching on unique carrier wave in the Target cell; When admitting, originally only need adjudicate, and need admit trial to the resource on all frequencies of Target cell now the single-frequency point resource of Target cell acquiescence; In multi-carrier frequency system, switch to which target carrier no matter switch the user, public information in its system must be obtained on the main carrier of appointment such as pilot channel (Beacon channel) information etc., and in single carrier frequency system behind the selected sub-district, with regard to known employed frequency.Therefore original handoff algorithms and process can't solve existing problem, and can't give full play to the more advantage of existing system resource.

Embodiment
Switching controls (HC) is an important component part in the RRM (RRM).In mobile communication system, user terminal is after initial sub-district and network are realized being connected, might be because a variety of causes need use the service of new sub-district, handoff procedure in the overloading frequency TDD/CDMA system is exactly to switch on certain carrier frequency of other suitable sector by the connection with user terminal, thereby makes service can not produce interruption.
Specifically describe the detailed process and the realization flow that switch in the overloading frequency TDD/CDMA system below.
In overloading frequently in the TDD/CDMA system, owing to do not have pilot channel on the subcarrier, so UE can't directly obtain the strength information of subcarrier, so must adopt the judgement foundation of the pilot frequency intensity of the main carrier in each sector as switching.Promptly all will carry out based on the pilot channel on the main carrier in each sector all about the measurement of pilot frequency intensity this moment, this comprises the measurement of pilot frequency intensity in the measurement of pilot frequency intensity in this sub-district and the adjacent sub-district.
Term herein " logic district " all refers to a sector in the multifrequency point TDD/CDMA system of shared common signal channel, and this logic district comprises a plurality of carrier waves, and one of them is a main carrier, and all the other are subcarrier.
Difference according to the UE handoff procedure, switching in the overloading frequency TDD/CDMA system has two kinds of possibilities: one, UE at first switches on the main carrier frequency of Target cell (logic district), can be transformed on the minor carrier by the channel adjustment in sub-district (logic district) subsequently; Two, UE is directly switch on the corresponding carrier frequency.Respectively these two kinds of schemes are described in detail below.
First handover scheme of the present invention is that UE at first switches to main carrier frequency, transfers to subcarrier again.The process of this scheme is: UE is that target carrier is measured and switched with the main carrier in each sector during switching, UE transfers to corresponding subcarrier according to certain strategy with it by the channel adjustment algorithm and gets on after switching on Target cell (logic district) main carrier.Switch on the main carrier of a certain sector as the user after, this handoff request and process just are through with, and the user on the main carrier is finished by the channel adjustment algorithm to the adjustment process of subcarrier.
This programme can adopt the switching flow of reserved resource, but must be on main carrier reserved resource, reserved resource not on subcarrier, this is because UE only can switch on the main carrier of each logic district when switching.
Specify detailed process below with reference to Fig. 1 and 2 according to switching controls in the multiple frequency point system of first handover scheme of the present invention.Fig. 1 is the switching flow of user equipment (UE) side.Fig. 2 is the switching flow figure of radio network controller (RNC) side.
As can be seen from Figure 1, the switching flow of UE side comprises and switches relevant measurement and hand-off execution process.
In step 101, behind the measurement configuration parameter that UE obtains being correlated with (reporting form etc. as measuring object, measurement), allocating and measuring type (such as measuring or inter-frequency measurement in the frequency), measurement cell list, measurement report form (as cycle triggering or Event triggered) and measuring amount etc.
In step 102, UE carries out measurement of correlation to this sub-district (logic district) and adjacent sub-district (logic district), comprises with the pilot channel on the main carrier of each sub-district (logic district) being the measurement of the pilot frequency intensity of measurement target;
In step 103, when satisfying triggering of corresponding condition such as cycle or trigger conditions, UE reporting measurement result has finished the measuring process relevant with switching;
In step 104, UE carry out step 105, otherwise is returned step 102 as if the switching command of receiving from RNC;
In step 105, insert on the main carrier of switching command indication: if UE does not have the synchronous and power control information about this main carrier, then UE need UpPCH and main carrier carry out synchronously and power control by sending at up direction; If UE has obtained synchronously and power contorl parameters in advance, directly carry out next step;
Set up new wireless connections in step 106 and target main carrier, promptly UE sets up dedicated channel (DCH) on the target main carrier;
In step 107, if UE and target main carrier are successfully set up new wireless connections, this UE should send handoff completion message (reshuffle finish message etc. as physical channel) to RNC; Simultaneously, this UE rests on and carries out work on the main carrier, by the channel adjustment algorithm it is adjusted to subcarrier subsequently and gets on, and has finished hand-off execution process.Otherwise enter step 108;
In step 108, if since set up the overlong time of DCH or target logic cell equipment can't operate as normal etc. abnormal cause, UE does not have to set up new wireless connections on the main carrier of indication, then this UE should send switch failure information (as physical channel reconfiguration failure message etc.) to RNC, and this UE recovers original link and connects simultaneously.
In step 201, RNC obtains the measurement result that UE reports;
In step 202, Target cell (logic district) tabulation that is used to switch is safeguarded, add or delete some sub-district (logic district), need to prove, because UE only switches access on the main carrier of each logic district, in fact this cell list is represented is the main carrier of each candidate target logic district of arranging according to priority;
In step 203, if the Target cell tabulation is not empty, carry out next step, otherwise this switching flow end, UE still keeps original Radio Link;
In step 204, RNC selects the highest logic district of priority from the Target cell tabulation, also promptly select the highest main carrier of priority;
In step 205, on selected main carrier, this user is carried out acceptance judging, the main purpose of acceptance judging is to check whether this main carrier has the ability to provide service for this user: if determine that main carrier can provide service for this user, then adjudicate this user and can insert; Otherwise refuse this user's access;
In step 206, check admission judgment result, if this user can insert on selected main carrier, then carry out step 209, otherwise carry out step 207;
In step 207, check the number of remaining candidate's main carrier in the Target cell tabulation, if the main carrier in the Target cell tabulation had all carried out the acceptance judging to this user, this switching flow finishes, UE still keeps original Radio Link, otherwise carry out step 208;
In step 208, RNC selects the highest main carrier of next priority from the Target cell tabulation after, this switching flow will carry out step 205;
In step 209, RNC sends switching command, as physical channel reconfiguration message, transmission channel reconfiguration message or radio bearer reconfiguration message etc.;
In step 210, after RNC sends switching command, receive corresponding feedback message from UE, if this message shows the UE handover success, then carry out step 211, otherwise carry out step 212;
In step 211, RNC deletes this user's former link configuration information, and this switching flow finishes, and UE keeps being connected with new main carrier;
In step 212, UE recovers original link and connects, the wireless connections that the RNC deletion is set up on new target main carrier to this user, and subsequently, this switching flow finishes, and UE keeps original wireless connections.
Second handover scheme of the present invention is that UE is directly switch to target carrier.The strategy of this scheme is: in the process of switching, UE is directly switch on the corresponding carriers (subcarrier or main carrier) of Target cell (logic district) after receiving switching command, and finally resides on this carrier wave.In this programme, when sending switching command, RNC should notify the main carrier information of UE Target cell (logic district), so that UE finishes some essential tasks in follow-up process, as read system message, carry out pilot frequency intensity measuring etc.
This programme can adopt the switching flow of resource reservation equally, but all must reserved resource on each carrier wave (comprising main carrier and subcarrier), and this is because UE this moment may switch on the main carrier, also may switch on each subcarrier.
Specify detailed process below with reference to Fig. 3 and 4 according to switching controls in the multiple frequency point system of second handover scheme of the present invention.Fig. 3 is the switching flow figure of user equipment (UE) side.Fig. 4 is the switching flow figure of radio network controller (RNC) side.
As can be seen from Figure 3, the switching flow of this user equipment (UE) side comprises and switches relevant measurement and hand-off execution process.
In step 301, behind the measurement configuration parameter that UE obtains being correlated with (measuring object, measurement report form etc.), allocating and measuring type (such as measuring or inter-frequency measurement in the frequency), measurement cell list, measurement report form (as cycle triggering or Event triggered) and measuring amount etc.;
In step 302, UE carries out measurement of correlation to this sub-district (logic district) and adjacent sub-district (logic district), and this comprises with the pilot channel on the main carrier of each sub-district (logic district) being the measurement of the pilot frequency intensity of measurement target;
In step 303, when satisfying corresponding condition (cycle triggers or Event triggered), UE reporting measurement result has finished the measuring process relevant with switching;
In step 304, UE, carry out step 305, otherwise is returned step 302 as physical channel reconfiguration message, transmission channel reconfiguration message or radio bearer reconfiguration message etc. as if the switching command of receiving from RNC;
In step 305, the target carrier of indicating in switching command (subcarrier or main carrier) inserts: if UE does not have the synchronous and power control information about target carrier, then UE need be undertaken synchronously by the main carrier that sends UpPCH and target logic sub-district at up direction and power control; If UE has obtained synchronously and power contorl parameters in advance, directly carry out next step;
In step 306, and target carrier (subcarrier or main carrier) sets up new wireless connections, and promptly UE sets up DCH on target carrier;
In step 307, if UE and target carrier are successfully set up new wireless connections, this UE sends handoff completion message to RNC, reshuffles as physical channel and finishes message etc., resides in simultaneously on this carrier wave and works, and has finished hand-off execution process.Otherwise enter step 308;
In step 308, if since set up the overlong time of DCH or target logic cell equipment can't operate as normal etc. abnormal cause, UE does not have to set up new wireless connections on the target carrier of indication, then this UE should send switch failure information to RNC, as physical channel reconfiguration failure message etc., this UE recovers original link and connects simultaneously.
In a logic district, have only shared control channel is arranged on the main carrier, therefore UE and target carrier (subcarrier or main carrier) synchronously should finishing by UE and corresponding main carrier synchronously, this process can be finished before UE receives switching command, also can finish after receiving switching command.The former need set up with the main carrier of a plurality of target logics sub-district and keep can shortening the needed time of handoff procedure so synchronously; The latter after receiving switching command only with switching command in main carrier in the target logic sub-district of indicating set up synchronously, UE transfers on the corresponding carrier wave again and works then.
In step 401, RNC obtains the measurement result that UE reports;
In step 402, tabulation is safeguarded to the Target cell (logic district) that is used to switch, adds or deletes some sub-district (be logic district, comprise main carrier and subcarrier);
In step 403, judge whether this Target cell is tabulated is empty, if the Target cell tabulation is not empty, enters step 404, otherwise this switching flow end, UE keeps original Radio Link;
In step 404, RNC selects the highest logic district of priority from the Target cell tabulation;
In step 405, in selected target logic sub-district (comprising main carrier and subcarrier), this user is carried out acceptance judging, when judgement, should analyze as unified resource a plurality of carrier waves in the logic district (comprising main carrier and subcarrier) to the user, as carrying out acceptance judging according to the dynamic method of adjusting each carrier wave priority of the size of the traffic carrying capacity on each carrier wave, guaranteeing professional balanced being distributed on each carrier wave in the logic district, thereby improve the admittance ability of whole logic district;
In step 406, check admission judgment result, if this user can insert in this logic district, carry out step 409, otherwise carry out step 407;
In step 407, check the number of remaining target logic sub-district in the Target cell tabulation, if all carried out acceptance judging in this user all logic district in the Target cell tabulation, this switching flow finishes, UE keeps original Radio Link, otherwise carry out step 408;
In step 408, from the Target cell tabulation, select the highest logic district of next priority, next step changes step 405 over to;
In step 409, RNC sends switching command, and as physical channel reconfiguration message, transmission channel reconfiguration message or radio bearer reconfiguration message etc., this order should comprise target carrier information and corresponding main carrier information;
In step 410, after RNC sends switching command, can receive feedback message from UE, if this message shows the UE handover success, carry out step 411, otherwise change step 412 over to;
In step 411, RNC deletes this user's former link configuration information, and this switching flow finishes, and UE keeps being connected with new carrier wave (a certain subcarrier or main carrier);
In step 412, UE recovers original link and connects, and the RNC deletion is gone up the wireless connections to this user of setting up in target carrier (a certain subcarrier or main carrier), and subsequently, this switching flow finishes, and UE keeps original Radio Link.
