Abstract
RNC divides multiple sub zones covered at same time in same sector into general sub zones and passive sub zones. RNC sends commands to request base station to build general sub zones and passive sub zones. Common transmission channels are built on and system information is updated on the said general sub zones only. Base station sends system broadcast on a general sub zones; in time of initiating to select and reselect sub zones, UE resides in a selected general sub zone, sending messages through common channel of the general sub zone and receiving messages carried by common channel. In time for allocating dedicated channel for UE, RNC allocates resources for the mobile terminal from a general sub zone and passive sub zone. The UE receives system broadcast information on a general sub zone. After releasing wireless resources, UE resides in a selected general sub zone. The invention increases capacity of TD-SCDMA system with features of modifying minor protocol and good compatibility.
Description
Technical field
The present invention relates to the method that multiple sectors at same covers in a kind of communication system, relate in particular to TD SDMA (TD_SCDMA) system and carry out the method that multiple sectors at same covers in same sector.
Background technology
The same with other mobile communication system, in order to satisfy the ever-increasing demand in mobile communication market, carrying out the covering of many sub-districts in same sector will be the important means that the TD-SCDMA system increases power system capacity.
For a plurality of sub-districts in the same sector, in present TD-SCDMA standard, all independently carry out at each sub-district for operation, the configuration of Radio Resource.Promptly to a plurality of sub-districts in the same sector, each sub-district is the complete common signal channel of separate configurations one cover separately, and wherein, the BCH of each sub-district (broadcast channel), FACH (forward access channel) and PCH (paging channel) are omnidirectional channel, cover whole sector.For portable terminal (UE), when carrying out cell selecting or gravity treatment in a plurality of sub-districts in this sector, also be independent each sub-district of distinguishing.
Many sub-districts coverage mode of this same sector of present standard definition, the base station not only requires very high when actual networking to transmitter power, and, under the situation of identical networking, the interference of minizone broadcast channel is also very serious, and the efficient of simultaneity factor is also very low.Typical case as shown in Figure 1, it is a cellular mobile communications networks that carries out the covering of many sub-districts in same sector, if this network uses the 10MHz bandwidth, there are 6 sub-districts each base station, is operated on 6 identical carrier frequencies.If a terminal is in several cell area intersections, it will face following particular problem:
The first, the Cell searching difficulty.In order to solve the initial cell search problem of time division duplex (TDD) system under Cellular Networks, TD-SCDMA has designed unique frame structure, realizes Cell searching by downward guide time slot (DwPTS).Do not have business datum in this time slot, signal to noise ratio is very high.And in network shown in Figure 1, because neighbor cell all will be at this frequency emission DwPTS, sign indicating number is different, and the position of each base station distance terminal is more or less the same again, and terminal receives the signal to noise ratio of this steering signal may be at-5dB, even poorer, and adjacent carrier is all similar.Like this, will make very difficulty of initial ranging.
The second, portable terminal is measured complicated.In network shown in Figure 1, this portable terminal may measure contiguous 18 sub-districts similar identical signal level.In present standard, terminal is only measured 6 sub-districts the strongest, faces far away more than the sub-district of this quantity, and terminal may be absorbed in the measuring process complicated, that be difficult to differentiate fully.
The 3rd, switch difficulty.Above-mentioned measurement result is delivered to RNC, will cause the difficulty that is switched and determined, and will cause the handoff procedure that do not stop, and system loading is obviously increased.The also switching determination that may lead to errors reduces the service quality of system.
The 4th, system effectiveness is low.A large amount of measurement results are delivered to RNC, and the handoff procedure that does not stop must will seriously reduce the efficient of system.
In order to address the above problem, in existing solution, adopt the mode of a plurality of carrier frequency in a sub-district (being equivalent to a sector), wherein has only a main carrier frequency, other be called assistant carrier frequency, in same sub-district, only on main carrier frequency, send DwPTS (descending pilot frequency time slot), UpPTS (uplink pilot time slot) and PCCPCH (Primary Common Control Physical Channel, fixed allocation is at TS0).This scheme is expanded the notion of a sub-district of a carrier frequency among the 3GPP, becomes a sub-district can comprise one or more carrier frequency the conceptual expansion of sub-district, to existing standard with realize bringing a lot of influences.Realize that this scheme need compare big change to the NBAP agreement, and brought some new problems for the physics of Node B and logical resource management; This scheme is also bigger to the influence of RNC when carrying out RRM simultaneously, because the notion of sub-district has been expanded, the managerial demand of Radio Resource increases the RRM of one-level carrier frequency on the basis of cell management.
Summary of the invention
The technical problem to be solved in the present invention provides the method that a kind of multiple sectors at same time in TD-SCDMA covers, and can carry out many sub-districts in same sector and cover, and increases the TD-SCDMA power system capacity, simultaneously existing protocol is changed little, compatible good.

Description of drawings
Fig. 1 is the terminal schematic diagram that is in the cellular mobile communications networks;
Fig. 2 is the flow chart that process is set up in embodiment of the invention sub-district.
Embodiment
The method that embodiment of the invention multiple sectors at same covers relates to be set up among UTRAN (UMTS Terrestrial radio access network) and allocating cell, UE carry out the resident and messaging in sub-district, are the UE assigned with dedicated channel, and processing such as order UE release dedicated channel.
The concrete steps of foundation and allocating cell are as follows in UTRAN, as shown in Figure 2:
Step 110, when carrying out the covering of many sub-districts in same sector, radio network controller (RNC) is defined as a cell set with these all sub-districts, and all sub-districts in the cell set are divided into common sub-district (normal cell) and passive sub-district (passive cell) two classes according to following definition:
Common sub-district: establish DwPCH channel (downlink pilot frequency channel) and PCCPCH channel (Primary Common Control Physical Channel) in such sub-district, also must set up S-CCPCH (auxilliary Common Control Channel), PICH (Page Indication Channel), PRACH (Physical Random Access Channel) and UpPCH (ascending pilot channel), FPACH common signal channels such as (physical access channel) in addition;
Passive sub-district: do not set up DwPCH and PCCPCH common signal channel in such sub-district, also do not set up S-CCPCH, PICH, PRACH, and UpPCH, common signal channels such as FPACH.
Each sub-district of the embodiment of the invention comprises a carrier frequency, and in a cell set, comprises a common sub-district at least, each passive cell association and only related common sub-district.If different cell parameter information is used in a common sub-district and all related passive sub-districts thereof, then the frequency of each sub-district can be the same or different; If identical cell parameter information is all used in a common sub-district and all related passive sub-districts thereof, then must all adopt different frequency to come distinguishing cell.Between the different common sub-district, same sector and the frequency between the adjacent common sub-district and cell parameter have at least one inequality.
Step 120, RNC determines the sub-district of a foundation, and send " request message is set up in the sub-district " to base station (Node B) by Iub interface, clearly indicate the kind of the sub-district of setting up, present embodiment is adopted the kind of coming distinguishing cell in the following method: if this sub-district is common sub-district, then this message comprises Primary Common Control Physical Channel information unit (PCCPCH Information LCR) and downlink pilot frequency channel information unit (DwPCH Information); If passive sub-district, then this message does not comprise Primary Common Control Physical Channel information unit and downlink pilot frequency channel information unit.Out of Memory unit in this message is identical with existing standard;
Step 130, Node B is after receiving " request message is set up in the sub-district ", set up the sub-district according to cell type, if comprise Primary Common Control Physical Channel information unit and downlink pilot frequency channel information unit in the message, be common sub-district then, when setting up the sub-district, set up PCCPCH channel and DwPCH channel respectively according to these two information units; If do not comprise Primary Common Control Physical Channel information unit and downlink pilot frequency channel information unit in the message, it then is passive sub-district, when setting up the sub-district, do not set up PCCPCH channel and DwPCH channel, the processing of out of Memory unit is identical with existing standard, then returns " response message is set up in the sub-district " to RNC after the sub-district is set up successfully;
Step 140, after RNC received " response message is set up in the sub-district ", if this sub-district is passive sub-district, the sub-district was set up process and is finished; If this sub-district is common sub-district, carry out next step;
Step 150 sends " Common transport channel is set up request message " at this common sub-district to Node B, identical in content that should " Common transport channel is set up request message " and the existing standard (3GPP TS 25.433 V4.9.0);
Step 160, Node B is after receiving " Common transport channel is set up request message ", according to the parameter that provides in the message, in respective cell, set up common signal channels such as auxilliary Common Control Channel, Page Indication Channel, Physical Random Access Channel, ascending control channel and physical access channel, return " Common transport channel is set up response message " after setting up successfully;
Step 170, after RNC receives " Common transport channel is set up response message ", send " system information updating message " at this common sub-district to Node B, identical in content that should " system information updating message " and the existing standard (3GPP TS 25.433 V4.9.0);
Step 180, Node B is after receiving " system information updating message ", according to the parameter executive system information update operation that provides in the message,, and return " system information renewal response message " to RNC if upgrade successfully then begin by PCCPCH channel transmitting system information broadcast;
Step 190 is after RNC receives this " system information renewal response message ", at the process of the setting up end of a common sub-district.
In the above-mentioned steps, if Node B then returns failed message to RNC handling that the sub-district is set up, Common transport channel is set up or system information failure when upgrading, the RNC processing of failing.
When RNC triggers UE and carries out cell selecting by " the Radio Resource control (RRC) connect set up message " or " cell update acknowledgement message " that sends to UE on common signal channel, if RNC wishes that UE carries out cell selecting on the frequency of current common sub-district, then in above-mentioned message, do not comprise frequency information unit (Frequency info), if RNC wishes that UE carries out cell selecting on other common cell frequency, will in above-mentioned message, comprise the frequency information unit.
UE carries out in cell selecting and gravity treatment and the resident process, needs DwPTS (descending pilot frequency time slot) with the descending synchronous code of determining the sub-district and frame regularly, and based on the basic midamble code and the scrambler of the further search cell of PCCPCH channel of TS0 time slot.Because network side is only set up in common sub-district and emission DwPTS and PCCPCH channel, therefore, even passive sub-district is identical with the frequency of common sub-district, UE also can only select with the common sub-district of gravity treatment and carry out resident.
Further, have only just to establish common signal channels such as Common transport channel such as auxilliary Common Control Channel, Page Indication Channel, Physical Random Access Channel, ascending control channel and physical access channel in the common sub-district, thereby UE can only use a common signal channel in the common sub-district to receive or send the message that is carried on the common signal channel.
Therefore, after adopting the method for present embodiment multiple sectors at same covering, the UE that is in free time (IDLE), cell paging (CELL-PCH), URA paging (URA-PCH) and cell forward access (CELL-FACH) state can only reside on the common sub-district, and uses the common signal channel on this common sub-district to receive or send the message that is carried on the common signal channel.This makes UE the signal quality to the PCCPCH channel of common sub-district measure, it still is example with Fig. 1, suppose that each sector comprises 6 sub-districts, wherein there are two to be common sub-district, then UE only need measure the signal quality of the PCCPCH channel of 2 common sub-districts, simplify the switching determination process of measuring process and RNC greatly, avoided frequent switching, improved system effectiveness.
RNC is that UE (common sub-district or passive sub-district) in a sub-district distributes dedicated wireless channel, and UE continues to keep or be transformed into the CELL-DCH state, sends or receive message in dedicated channel.If RNC is UE distribution dedicated radio resources in a common sub-district, then UE while receiving broadcasting information on this common sub-district; If RNC is UE and distributes dedicated radio resources in a passive sub-district, then UE with the common sub-district of this passive cell association on receiving broadcasting information.
RNC is that UE distributes the message of dedicated radio resources to comprise " cell update acknowledgement message ", " switching to the UTRAN command messages ", " physical channel reconfiguration message ", " transmission channel reconfiguration message ", " radio bearer reconfiguration message " and " radio bearer is set up message " etc.
If RNC for UE distributes private resource, only is required to be the Target cell of UE assignment of allocation Radio Resource in the message of distributing dedicated radio resources in common sub-district, UE is the receiving system broadcast message on the common sub-district of this target.Whether the frequency information of sub-district (can be common sub-district or passive sub-district) that at this moment only needs to judge the current resident or distributing radio resource of UE is identical with the common sub-district of cell parameter information and target, if both frequency informations and/or cell parameter information are inequality, should comprise the frequency information and/or the cell parameter information unit of this common sub-district of target in the message;
If RNC distributes private resource for UE in passive sub-district, in distributing the message of dedicated radio resources except being the passive sub-district of target of UE assignment of allocation Radio Resource, also need to specify the common sub-district of receiving system broadcast message for UE, therefore, whether the frequency of sub-district of judging the current resident or distributing radio resource of UE except needs is identical with the passive sub-district of cell parameter information and target, inequalityly should in message, comprise outside the corresponding information unit, whether the frequency information of common sub-district that also needs to judge the current receiving broadcasting information of UE is identical with the common sub-district of target of specifying receiving broadcasting information with cell parameter information, if both frequency informations and/or cell parameter information are inequality, should comprise the frequency information and/or the cell parameter information unit of this common sub-district of target in the message.
At Target cell is under the situation of passive sub-district, RNC is that the passive sub-district of the target of UE appointment may have identical frequency information and cell parameter information with the sub-district of specifying receiving broadcasting information, if the sub-district of the current resident or distributing radio resource of passive sub-district of target and UE at this moment, and the frequency information and/or the cell parameter information of the common sub-district of the common sub-district of appointment receiving broadcasting information and the current receiving broadcasting information of UE are inequality, also can only comprise a correspondent frequency information unit and/or cell parameter information unit in the message of distributing dedicated radio resources.
Suppose each common sub-district and the related identical cell parameter information of all passive sub-districts uses thereof, UE switches to the passive sub-district related with it from a common sub-district, because both cell parameters are identical, the frequency difference is so only need comprise the frequency information unit of the passive sub-district of target in the message of distributing radio resource.Because UE switches receiving system broadcast messages on same common sub-district of front and back, therefore do not need to comprise the frequency information unit and the cell parameter information unit of the common sub-district of specifying receiving broadcasting information simultaneously.
Suppose each common sub-district and the related identical cell parameter information of all passive sub-districts uses thereof again, UE switches to the passive sub-district of another one from a passive sub-district, and the cell parameter of the common sub-district of these two passive cell association is inequality, then in the message of distributing radio resource, the cell parameter information unit that need comprise the common sub-district of the passive cell association of target, because the cell parameter information of the passive sub-district of target is identical with it, can omit the cell parameter information unit of the passive sub-district of target.
When RNC determines common sub-district of deletion when (at this moment, in the cell set at this place, common sub-district, having two common sub-districts at least), in RNC, need will be original with all passive cell association of this common cell association to other common sub-district; And, for being in the CELL-DCH state and residing in UE on these passive sub-districts, RNC need specify the frequency and/or the cell parameter information of the new common sub-district of UE receiving system broadcast message by comprise Frequency info and/or Primary CCPCH info information unit in above-mentioned message for UE distribution dedicated radio resources;
RNC is when distributing dedicated radio resources for UE, the Radio Resource of the TS0 time slot in the passive sub-district does not use, perhaps in the radio frames resource that the PCCPCH channel in the common sub-district of its association does not take, the mode that adopts frame to distribute is that UE distributes dedicated radio resources, shares with the timesharing that the achieve frame branch is mixed.Be that passive sub-district or TS0 time slot do not use; Must be subjected to the restriction of the radio frames that the Primary Common Control Physical Channel in the common sub-district of its association takies when using.
RNC discharges dedicated wireless channel by radio bearer release message order UE, and UE leaves the CELL-DCH state.In this message, can comprise Frequency info information unit, indication UE carries out cell selecting on specified frequency, resident to select a suitable common sub-district to carry out, and uses the common signal channel in this common sub-district to receive or send the message that is carried on the common signal channel.
In sum, the inventive method is in the TD-SCDMA system, Primary Common Control Physical Channel and descending pilot frequency time slot and other common signal channel are limited on the common sub-district, reduced the presence of intercell interference of Primary Common Control Physical Channel and descending pilot frequency time slot, improved systematic function, terminal initial is searched for quick and precisely.Only on common sub-district, launch common signal channel simultaneously, will reduce the interference of native system greatly other system; Measure the sub-district when switch the terminal sub-district and reduce, measuring process is clear and definite, thereby network side is more accurate when carrying out switch decision based on measurement; In addition, the present invention is realizing that many sub-districts are carried out in same sector to be covered, and when overcoming the defective of aforesaid current standard, the NBAP agreement of existing protocol especially Iub interface is changed minimum, therefore also best for protocol compatibility.
