Description
Technical field
The present invention relates to moving communicating field, specifically, relate to processing method and the system of base station scheduling in a kind of UTRAN (UMTSTerrestrial Radio Access Network, UMTS (Universal MobileTelecommunications System) land radio access web) system.
Background technology
In the construction of Radio Network System, in-door covering has become the most important thing of networking, rational in-door covering scheme can make network system farthest play its effect on the one hand, for operator creates larger value, also greatly can save the networking cost of operator on the other hand, really realize low input high repayment.Thus, the radio reception device that one is called Home eNodeB (Home NodeB, HNB) arises at the historic moment.Home eNodeB is deployed in the private site uses such as family, group, company or school as the dedicated resources of private user, various High-speed wireless access service can be provided to user and to provide on rate preferential, make up existing distributed cellular radio communication system simultaneously and cover not enough defect.
It is the reserved frequency resource of Home eNodeB that Home eNodeB can use operator specially, also the frequency resource identical with macro base station can be used, community under macro base station (NodeB) covers is called macrocell, and the community under Home eNodeB covers is called home base station cells.Current Home eNodeB has three kinds of access modules: open mode, closed mode and mixed mode, wherein, the Home eNodeB of open mode allows all user's accesses, corresponding community is called the home base station cells (open cell) of open mode, this community and common macrocell as broad as long, the Home eNodeB of closed mode only allows the user's access through authorizing, as the kinsfolk authorized, the users such as member of community, these constitute a closed user group (CSG through the user's (being called for short Member Users) authorized, Closed Subscriber Group), identify with CSG ID (CSGIdentity), user allows each closed user group mark accessed, be stored in subscriber equipment (UserEquipment, referred to as UE) in, community under the Home eNodeB covering of closed mode is called the home base station cells of closed mode, be called for short CSG cell, the Home eNodeB of mixed mode also has a closed user group, the Home eNodeB of mixed mode is except allowing Member Users and accessing, also allow non-member user access, but Member Users enjoys the preferential guarantee power of service quality, priority allocation power in resource and the preferential right on rate, corresponding community is called the home base station cells (Hybrid Cell) of mixed mode.
CSG cell only allows Member Users to access, Hybrid community enjoys priority to Member Users, for travelling performance excellent under meeting connected state, UE needs initially to access judgement (Preliminary Access Check) to CSG or Hybrid community, namely UE needs the System information block 3 or 4 (System Information Block3/4, SIB3/4) reading CSG or Hybrid community.Whether UE allows each CSG ID accessed according to the user preserved in CSG ID and UE broadcasted in SIB3/4, judge whether to allow this CSG or Hybrid community of access, and access with member identities.In addition each home base station cells has a main scrambling code identification (Primary Scrambling Code, PSC) and one global cell identity (Cell Global Identifier, CGI), the limited amount (512) of PSC, along with a large amount of deployment of Home eNodeB, unavoidably must there will be the situation that two or more home base station cells uses identical PSC, and CGI is unique in public land mobile network (Public Land Mobile Network, PLMN) scope.UE directly can obtain the PSC of home base station cells in Cell searching or measuring process, and CGI just can must be obtained by the SIB3/4 reading this community.Macrocell is resided in so that UE is current, if there is two or more home base station cells to use identical PSC, target household base station cell cannot be uniquely determined after macrocell receives the PSC of the home base station cells that UE reports, for solving the problem, UE is needed to read the SIB3/4 of target household base station cell, obtain CGI and reported macrocell, thus uniquely determining target household base station cell.Usual network side knows which frequency is the special frequency being exclusively used in CSG cell, and network side also knows the PSC scope (PSC Range) that on mixing frequency, CSG cell uses.
Because Home eNodeB has mobility as the equipment of plug and play, and magnanimity is disposed, generally can not configuring adjacent cell relation between macrocell and CSG cell, namely UE is the information that can not obtain adjacent C SG community when macrocell is switched to CSG cell, and UE needs the information such as CSG ID, CGI of real-time detection acquisition CSG cell just can reach the object of switching.Simultaneously because UE has preferential or preferential right in the CSG cell that some is authorized, therefore UE is in order to be switched to suitable CSG cell as soon as possible, need the CSG cell information of preserving the closed mode having accessed or accessed, this part information is called fingerprint (or footprint), by fingerprint, UE can initiatively and detect the CSG cell of mandate in time, and fingerprint can comprise the content such as neighboring BS information, address of the PSC of CSG cell, frequency, this CSG cell.UE also needs the home base station cells (i.e. Hybrid Cell) of (i.e. member) mixed mode preserving the mandate accessing or accessed, and for the Hybrid community of non-member, UE does not need to preserve fingerprint information.Due to plug and play and the mobility of Home eNodeB, if the PSC of home base station cells or frequency there occurs change, UE still needs detect within a certain period of time and complete switching flow.
The band of position that in fingerprint, information comprises is called fingerprint region.When the UE being in connection status enters fingerprint region, if (network side notifies UE by dedicated signaling to the ability that network side has to CSG/Hybrid cell merge, whether network side allows UE to report close to instruction by Survey control message arrangement), instruction (the Proximity Indication that UE informing network side is close, comprise and enter and leave two states, now UE reports and gets the hang of), frequency information and access network technology (the Radio Access Technology at place, CSG/Hybrid community is comprised in the instruction that this is close, RAT, comprise E-UTRAN or UTRAN).If network side does not configure measurement configuration (comprising measurement clearance or compact model) of place, CSG/Hybrid community frequency, network side will configure measurement configuration (comprising measurement clearance or compact model) of described frequency for this UE; UE is according to the neighbor cell of frequency described in new measurement allocating and measuring; If there is the community meeting report condition, UE sends measurement report to network side; Network side will, according to measurement report, specify UE to read the system message of suitable CSG/Hybrid community; After UE obtains the system message of network appointment CSG/Hybrid community, implement initially to access judgement (Preliminary Access Check), and report network side.If network side has configured the measurement configuration of place, CSG/Hybrid community frequency, network side can specify UE to read the system message of suitable CSG/Hybrid community according to measurement report; After UE obtains the system message of network appointment CSG/Hybrid community, implement initially to access judgement (Preliminary Access Check), and report network side.Initial access judgement information that network side reports according to UE (or handover preparation information, handoverpreparation information) implement handover decisions.
As shown in Figure 1, radio network controller (RadioNetwork Controller) is connected with base station by Iub interface the schematic layout pattern of UTRAN grid, is connected with core net by Iu interface.When the UE being positioned at RNC jurisdiction district is in connection status, when needing the system message obtaining adjacent C SG/Hybrid community, by RRC signaling (Measurement Control), RNC notifies that UE obtains the system message of specifying CSG/Hybrid community (by setting PSC), after UE receives this signaling, if obtain the system message of alien frequencies or different system CSG/Hybrid community, UE needs automatically to create measurement clearance (Autonomous measurement GAP) and goes to obtain the system message of specifying CSG/Hybrid community, in the measurement clearance automatically created, UE interrupts the communication with Serving cell.In this process, the base station that UE belongs to does not know that UE has interrupted the communication with Serving cell, also can continue to dispatch this UE, is UE Resources allocation, sends data message to this UE, and this is by interface-free resources a large amount of for waste.Special in HSDPA or HSUPA, mixed automatic retransfer entity (HARQ) is positioned at base station, if base station there is no confirmation (ACK) to the mass data that UE sends, the wireless link existing problems that this UE may be thought in base station, may cause the behavior of network side release UE.Existing agreement is not also for the processing method of this problem.

Below in conjunction with embodiment, illustrate technical scheme of the present invention further.
Embodiment one
In UTRAN system, UE is positioned at macro base station (base station 1, the radio network controller belonging to base station 1 is called source RNC or Serving RNC or control RNC) jurisdiction district 1, is in connection status.Network side is that UE is configured with measurement configuration, and UE implements measurement according to measurement configuration, reports the cell information meeting report condition.In this embodiment, base station 1 is the Current Serving BTS that UE belongs to, and this base station provides Radio Link Service for UE, and the Current Serving BTS in other embodiments is equivalent in meaning therewith.As shown in Figure 2, comprising:
Step 101, sometime, UE, according to footprint or the fingerprint information of preserving, determines CSG or the Hybrid community close to the mandate of access before certain, and UE reports close to instruction (entering) to source RNC;
Usually, when the position of UE movement is on the books in footprint, UE thinks close to the community of access in the past, reports close to instruction to source RNC.
Frequency information (frequency f 1) and the access network technology (being UTRAN in the present embodiment) of CSG cell or Hybrid community is comprised in this is close to instruction.
Step 102, source RNC receive that UE reports close to after instruction, configure owing to there is no the measurement on configuration frequency f1 before, network side sends the signaling (by Measurement Control, comprising the PSC scope of the configuration of compact model and the CSG/Hybrid community of needs measurement) newly-increased frequency f 1 being measured configuration to UE;
Step 103, after UE receives this signaling, performs the measurement in frequency f 1, and the neighbor cell in assessment frequency f 1, reports the cell information meeting report condition to network side; Such as, sometime, UE reports community frequency f 1 meeting report condition to comprise community 2, community 3 and community 4 to source RNC;
Step 104, according to the PSC of each community, source RNC determines that community 2 is CSG cell, notify that UE obtains the system message of community 2 by RRC signaling (Measurement Control);
Source RNC can obtain the temporal information of the system message of community 2 by signaling settings UE, comprise following information one or more: initial time, termination time, time span, and the mode that can adopt acquiescence.
Step 105, source RNC is by the state information of this UE of Iub interface informing base station 1;
RNC is after the decision making UE acquisition neighbor cell system message, and RNC can send to UE the RRC signaling obtaining system information in neighboring area while the state information sending this UE to base station 1, and that is, this step can be carried out with step 104 simultaneously.But this step also can perform before step 104.
The state information of UE can adopt the mode of signaling to indicate.
The state information of this UE can represent one of following state: UE obtains the state of neighbor cell system message, described UE creates the state of measurement clearance (autonomous measurement GAP) automatically, the state of described UE and Serving cell (community 1) interrupt communication.
The state information of this UE can also comprise temporal information, and described temporal information is used to indicate the time of UE status, comprises initial time and termination time, and this termination time also can be shown by time lengths table.The initial time of source RNC informing base station 1 and termination time can be absolute times, as adopted the frame number BFN of base station 1; Also can be relative time, a period of time of being separated by receive the state information of this UE as being defined as after.The state information of UE also can not comprise clear and definite persond eixis, and such as now initial time adopts default configuration, receive the time of the signaling of instruction UE state information, and time span is specified, is namely also acquiescence as being defaulted as base station by agreement.
It should be noted that, described temporal information can adopt the mode of default configuration, one or more in namely prespecified following information: initial time, termination time, time span.Preferably, initial time can be defaulted as the time corresponding to signaling that base station receives instruction UE state information, now RNC only can carry time span or termination time in the state information of UE, if time span or termination time were also preconfigured, then RNC also can not carry.
The state information of UE can also comprise the access network technology (Radio Access Technology, RAT) belonging to neighbor cell and/or frequency that UE obtains system message, is UTRAN and/or frequency f 1 herein.Because the transformat of the system message of UTRAN system and E-UTRAN system is different, as in UTRAN system, the length of system message is 20ms, and in E-UTRAN system, the length of system message is 1ms, and therefore the access network technology belonging to neighbor cell of base station acquisition UE acquisition system message can adopt different scheduling strategies.If only there is frequency information not have access technology information in state information, according to frequency information, base station can judge that UE obtains the access network technology belonging to the neighbor cell of system message.
In UTRAN system, RNC obtains the timing information of administrative base station and jurisdiction district, base station by synchronization mechanism, RNC is at the timing information for setting UE when UE connects, and therefore RNC can set initial time and/or termination time information in the status signaling of UE sending to base station.
Step 106, after base station 1 receives the state information of this UE, preserves this part information, and is applied to the scheduling of this UE, namely controls the scheduling to UE according to the state information of UE, and does not trigger abnormal flow process;
Such as, base station 1 obtains in the time period of neighbor cell system message at the UE that state information indicates reduces or avoids the scheduling to this UE, such as comprise one or more in following situation: reduce and send DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel), do not send DPCCH, reduce send DPDCH (Dedicated Physical Data Channel, Dedicated Physical Data Channel), do not send DPDCH.Especially, if UE has set up HSDPA business, because the partial function of MAC layer corresponding to this UE is realized by base station 1, HARQ entity is positioned at base station 1, distribution, the scheduling of this UE resource is responsible for by base station 1, base station 1, after the state obtaining UE, is reduced or avoids the scheduling to this UE resource (comprising the distribution of resource).The flow process of abnormal (as releasing request), when UE continuous print does not respond, can not be triggered in base station 1.
Step 107, UE is after the system message getting community 2, implement initially to access judgement (Preliminary Access Check), to judge whether it allows to access this community (such as by the CSG ID in white list and system message), initial access judgement information (or handover preparation information is reported to source RNC, handover preparation information), source RNC implements handover decisions accordingly.
If UE obtains system information in neighboring area and report initial access judgement information within the time of network settings, source RNC can send the new state of UE to base station 1, this UE of informing base station 1 has recovered normal communication, and the normal scheduling to this UE is recovered after receiving this signaling in base station 1.
Embodiment two
In UTRAN system, UE is positioned at macro base station (base station 1, the radio network controller belonging to base station 1 is called source RNC or Serving RNC or control RNC) jurisdiction district 1, is in connection status.Network side is that UE is configured with measurement configuration, and UE implements measurement according to measurement configuration, reports the cell information meeting report condition.As shown in Figure 3, comprising:
Step 201, sometime, UE, according to footprint or the fingerprint information of preserving, determines CSG or the Hybrid community close to the mandate of access before certain, and UE reports close to instruction (entering) to source RNC;
Frequency information (frequency f 1) and the access network technology (as E-UTRAN) of CSG cell or Hybrid community is comprised in this is close to instruction.
Step 202, source RNC receive that UE reports close to after instruction, wait for UE reporting measurement reports;
Due to the measurement configuration before on configuration frequency f1, therefore network side does not need newly-increasedly to measure configuration, and the measurement report notice UE on the f1 that only need report according to UE obtains the system message of suitable CSG/Hybrid community.
Step 203, sometime, UE reports community frequency f 1 meeting report condition to comprise community 2, community 3 and community 4 to source RNC;
Step 204, source RNC is according to PCI (the physical cell identify of each community, Physical Cell Identifier) determine that community 2 is CSG cell, by RRC signaling (Measurement Control), source RNC notifies that UE obtains the system message of community 2;
Source RNC can obtain the temporal information of the system message of community 2 by signaling settings UE, also can adopt the mode of acquiescence.The present embodiment adopts the mode of acquiescence, and the time defining UE acquisition system message is 150 milliseconds.
Step 205, after UE receives this signaling, automatically can create measurement clearance (autonomous measurement GAP) to obtain the system message of community 2 in back to back 150 milliseconds, after 150 milliseconds, UE needs to recover the communication with Serving cell (community 1);
If UE is in soft changing state, UE can keep connecting from multiple community (can belong to different base stations) simultaneously, and UE needs to recover the communication with this multiple community after described 150 milliseconds.
Step 206, source RNC is by the state information of this UE of Iub interface informing base station 1;
In the present embodiment, temporal information in UE state information adopts the mode of acquiescence, namely from the time of 150 milliseconds after base station receives this signaling.
Source RNC can pass through existing Iub signaling base station 1, as adopted the signaling of Radio LinkReconfiguration Prepare or UE Status Update Command etc., also can increase signaling newly for transmitting the state of UE.
In the present embodiment, the state of UE can also comprise the access network technology (Radio Access Technology, RAT) belonging to neighbor cell that UE obtains system message, is E-UTRAN herein.Because the transformat of the system message of UTRAN system and E-UTRAN system is different, the access network technology belonging to neighbor cell that base station obtains UE acquisition system message can adopt different scheduling strategies.
Step 207, after base station 1 receives the state information of this UE, preserves this part information, is applied to the scheduling of this UE, namely controls the scheduling to UE according to the state information of UE, and does not trigger abnormal flow process;
Such as, base station 1 is reduced or is avoided the scheduling to this UE within the time period that the UE that state information indicates obtains neighbor cell system message.Especially, if UE has set up HSDPA or HSUPA business, because the partial function of MAC layer corresponding to this UE is realized by base station 1, HARQ entity is positioned at base station 1, distribution, the scheduling of this UE resource is responsible for by base station 1, base station 1, after the state obtaining UE, is reduced or avoids the scheduling to this UE resource (comprising the distribution of resource).The flow process of abnormal (as releasing request), when UE continuous print does not respond, can not be triggered in base station 1.
Step 208, UE, after the system message getting community 2, implements initially to access judgement, and report initial access judgement information (or handover preparation information) to source RNC, source RNC implements handover decisions accordingly.
In the present embodiment, UE is not in soft changing state, if UE keeps being connected (establishing radio links) with multiple community simultaneously, these communities belong to different base stations, and source RNC need send the state of UE to these different base stations; Preferably, source RNC only sends the state of UE to the base station of the HARQ entity having this UE; If these different base stations belong to different RNC, source RNC sends the state of this UE to these base stations by different RNC via Iur interface.
Embodiment three
In UTRAN system, UE is positioned at macro base station (base station 1, the radio network controller belonging to base station 1 is called source RNC or Serving RNC or control RNC) jurisdiction district 1, is in connection status.Network side is that UE is configured with measurement configuration, and UE implements measurement according to measurement configuration, reports the cell information meeting report condition.As shown in Figure 4, comprising:
Step 301, sometime, UE, according to footprint or the fingerprint information of preserving, determines CSG or the Hybrid community close to the mandate of access before certain, and UE reports close to instruction (entering) to network side;
Frequency information (frequency f 1) and the access network technology (being UTRAN in the present embodiment) of CSG cell or Hybrid community is comprised in this is close to instruction.
Step 302, source RNC receive that UE reports close to after instruction, configure owing to there is no the measurement on configuration frequency f1 before, network side sends the signaling (by Measurement Control, comprising the PSC scope of the configuration of compact model and the CSG/Hybrid community of needs measurement) newly-increased frequency f 1 being measured configuration to UE;
Step 303, after UE receives this signaling, performs the measurement in frequency f 1, and the neighbor cell in assessment frequency f 1, reports the cell information meeting report condition to network side; Such as, sometime, UE reports community frequency f 1 meeting report condition to comprise community 2, community 3 and community 4 to source RNC;
Step 304, according to the PSC of each community, source RNC determines that community 2 is CSG cell, source RNC obtains the system message of community 2 by RRC signaling UE;
Step 305, UE reports the state information of this UE after receiving the signaling of the system message obtaining community 2 to base station 1;
The state information of this UE can represent one of following state: UE obtains the state of neighbor cell system message, described UE creates the state of measurement clearance automatically, the state of described UE and Serving cell (community 1) interrupt communication; Can also comprise the temporal information that UE is in above-mentioned state, described temporal information is initial time and/or termination time, and wherein the termination time can replace by time span.Initial time and termination time can the mode of signaling instruction or the modes of employing acquiescence.The state of this UE can also comprise the access network technology (such as UTRAN system) belonging to adjacent area and/or frequency information that obtain system message.
Step 306, after base station 1 receives the state information of this UE, preserves this part information, and is applied to the scheduling of this UE;
Such as, base station 1 is reduced during this period of time in UE acquisition neighbor cell system message or avoids the scheduling to this UE.Especially, if UE has set up HSDPA or HSUPA business, because the partial function of MAC layer corresponding to this UE is realized by base station 1, HARQ entity is positioned at base station 1, distribution, the scheduling of this UE resource is responsible for by base station 1, base station 1, after the state obtaining UE, is reduced or avoids the scheduling to this UE resource (comprising the distribution of resource).The flow process of abnormal (as releasing request), when UE continuous print does not respond, can not be triggered in base station 1.
Step 307, UE, after the system message getting community 2, implements initially to access judgement, and report initial access judgement information to source RNC, source RNC implements handover decisions accordingly.
UE also can after the system message getting community 2, the new state information of UE is reported to base station 1, now the state information of UE represents that UE has got the system message of neighbor cell, after base station 1 receives the new state of UE, recovers to dispatch normally this UE.
It should be noted that, UE is in HSDPA or HSUPA state, if the state information of UE is not known in the base station belonging to UE, will cause the serious wasting of resources, UE also after determining that UE obtains the system message of designated cell, can be become Cell_DCH state from HSDPA or HSUPA State Transferring by source RNC.
