Abstract
The method suitable to broad band CDMA system includes following steps: operation and maintenance center completes configuration of label value range of system message 1 corresponding to location area code and routing area code, and the configuration is sent to database at background for conservation; in procedure for creating subzone, foreground sends message to database at background based on subzone id so as to obtain label value range of system message 1 corresponding to location area code and routing area code for the subzone, and sends to base station through request message of system message updating, and is broadcasted through base station in subzone. Network planning guarantees that label value range of system message 1 is identical in subzones in same LAC or inside RAC, and label value range of system message 1 is not identical in adjacent subzones in different LAC or RAC.
Description
Technical field
The present invention relates to the CDMA mobile telecommunication technical field, relate in particular to the technical field of cell parameter configuration.
Technical background
Code division multiple access (CDMA) is a kind of spread spectrum mobile communication technology.Spread spectrum technic mainly applies to military communication in the early stage, because its remarkable performance also will obtain to use widely in the commercial communication field.Now there has been commercial cdma cellular mobile communication system to operate in the telecommunications network.
For improving the capacity of mobile communication system, cellular system is generally adopted.In cellular mobile telecommunication system, whole network is made of some sub-districts, and different districts is by different configuration attributes, such as the PLMN zone under the sub-district, sub-district available channel type or the like.These attributes are only relevant with the sub-district usually, and little with the different user relation in the sub-district, in order effectively to improve the efficient of this category information of Network Transmission, generally adopt the mode of " broadcasting " in the various mobile communication system, promptly in the sub-district, set up broadcast channel, the general information of periodic broadcast sub-district.The travelling carriage that enters this sub-district just can obtain the essential information of sub-district, thereby finish the general controls of network terminal to the user of this sub-district by receiving broadcast channel.
And at user terminal (User Equipement, UE), each System information block all has attribute separately: what state to think that this System information block is effective (UE mode/state when block is valid) such as validity scope (Area scope), UE at, UE reads this System information block (UE mode/state when block is read), schedule information (Scheduling information) and alter mode (Modification of system information) at what state.
For the validity scope of System information block, it is meant this System information block is effective in what scope.Have only two kinds of validity scope: PLMN and CELL at all System information blocks among the WCDMA.If the validity scope of a System information block is CELL, UE only can think that the content of this System information block is effective in this sub-district so, after this UE has selected the another one sub-district, can think automatically that the content of this System information block is invalid, and read this System information block of up-to-date sub-district again; If the validity scope of System information block is PLMN, UE can think that this System information block all is effective at whole PLMN so, after UE has selected a new sub-district, the label value of this System information block that the label value and the UE of this System information block in the new sub-district can be preserved in original sub-district relatively, if these two label values are identical, UE can think that the content of this System information block in these two sub-districts is consistent so, and can not read the fast content of this system message; If these two different words of label value, UE can think that this System information block is different in these two sub-districts so, and can read the content of this System information block in the new sub-district again.
In all system messages, the validity scope of system message 1 is PLMN, according to top description, when UE from a sub-district gravity treatment behind the another one sub-district, can read the label value PLMN VALUE TAG of this cell system message 1, compare with the label value of preserving then, thereby whether decision needs the content in the read system message 1.In system message 1, broadcasted the parameter of a large amount of Non-Access Stratums (NAS), such as: Location Area Code (Location Area Code, LAC) or Routing Area Code (Routing AreaCode, RAC) and the timer under some idle pulleys and the connection mode etc.According to the network planning, LAC or RAC can comprise a lot of sub-districts, that is to say, a lot of adjacent sub-districts have identical LAC or RAC.UE is own to where for CN can be known, such as at which LAC or at which RAC, work as UE so and entered into another one LAC or RAC from a LAC or RAC, just need carry out a position upgrades or routing update, which position CN just can know UE in like this, thereby paging smoothly is to this UE.In the network planning, when two neighbor cells have different LAC or RAC, if UE from one of them sub-district gravity treatment to the another one sub-district, just need carry out position and upgrade or routing update.Does but how UE know that the LAC of these two sub-districts or RAC are different? it is different having only UE to read just can to know after the content of system message 1 of another one sub-district this sub-district and original sub-district, is necessary for the different label value PLMN VALUE TAG of these two cell configuration for this reason.
But how to be different different system message 1 label values of cell configuration? the description and the implementation method of not being correlated with in the prior protocols, and industry does not have clear and definite solution at this problem yet at present.
A kind of technical scheme is according to describing among the 3GPP agreement TS25331, the scope of the label value PLMN VALUE TAG of system message 1 is (1～256), can distribute in 1 to 256 any one for system message 1 at each sub-district, present a kind of scheme is to carry out Random assignment at 1～256.From (1～256), select a value to distribute to the system message 1 of sub-district at random in the time of each system message update, as the label value of this cell system message 1.Below " label value PLMN VALUE TAG " be referred to as " label value ".The shortcoming of this technology clearly, the first, cause adjacent sub-district to have identical label value possibly at each sub-district mean allocation with Different L AC or RAC, will occur like this when UE from one of them sub-district gravity treatment after the another one sub-district, the label value of finding the system message 1 of two sub-districts is the same, thereby the content in can read system message 1, and do not know to have changed LAC or RAC, CN does not just know that this UE has changed the position yet, will cause CN paging to arrive this UE like this.The second, have identical LAC or RAC when two sub-districts, the parameter of other system message 1 is also all identical, adopts this scheme may cause these two sub-districts to have different label values so.Can cause UE to move to the another one sub-district from one of them sub-district like this and the content of read system message 1 again, the time waste that precocity is unnecessary causes UE power consumption to increase.Three, at same sub-district, after other content in the system message 1 has taken place to upgrade, because twice label value was the same before and after this mode at random of employing caused possibly, thereby make the UE that resides in this sub-district think that the content of system message 1 does not have to upgrade, and can not read the content in the new system message 1.
Another technical scheme is that each sub-district basis is carried out cycle applications from (1～256), and the label value of the system message 1 of this sub-district was 1 after just foundation had been finished such as the sub-district, and each later on renewal just adds 1 with this label value, until 256, be again 1 then.Also there is this intrinsic defective in this method.First, if each sub-district when setting up all with the label value of system message 1 from some values, such as being 1, so these sub-districts all set up together finish after, system message 1 label value of all sub-districts is the same, if two neighbor cells have different LAC or RAC, label value also is the same so.The situation that still can occur not carrying out position or routing update at UE.The second, at several sub-districts with different LAC or RAC, if for a certain reason, (this is a kind of opposite extreme situations certainly in the system message 1 frequent renewal of one of them sub-district, but also exist this risk), to have upgraded one-period may be the same with system message 1 label value of other sub-district to the label value of the system message 1 of this sub-district so.So still can cause UE to move and do not send the position and upgrade and Routing Area Update in different LAC or RAC sub-district.
Summary of the invention
Purpose of the present invention proposes the collocation method of the label value of a kind of Wideband Code Division Multiple Access (WCDMA) (WCDMA) system message 1 exactly, can be according to the network planning, label value scope for the different system message 1 of each LAC or RAC configuration, guarantee to have identical system message 1 label value scope in the sub-district of same LAC or RAC inside, adjacent and be in the sub-district of Different L AC or RAC, the label value of its system message 1 can be not identical.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
As shown in Figure 1, at the OMC of RNC, planning personnel (perhaps user) sets up needed LAC of system and RAC according to the planning demand by OMC.In configuration LAC or RAC, just the label value scope configuration of LAC or the pairing system message 1 of RAC is finished, after the OMC configuration is finished, can send to the database on backstage by message, with the label value scope correspondence of LAC or RAC in tables of data, after database is finished configuration to all data, send response message to OMC.
Set up the sub-district according to planning, OMC sends the sub-district and is established to the foreground, in the process that the foreground carries out setting up the sub-district, the foreground sends message according to cell ID to database, obtains the label value scope of the system message 1 of pairing LAC in this sub-district (if sub-district, CS territory) or RAC (if PS territory).
Label value scope according to the pairing system message 1 in sub-district, from scope, wherein take out a value and (perhaps adopt minimum one, perhaps adopt maximum one, perhaps take or the like at random, if it is also identical need to guarantee to have the parameter of other system message 1 of sub-district of identical LAC or RAC, need the identical label value of configuration), with the label value of this value as the system message 1 of this sub-district, and send to NODEB by the system message update request message, broadcast in the sub-district by NODEB.
Upgrade the label value scope of system message 1 of certain LAC or RAC correspondence the user after, OMC sends a message to database, notification database is upgraded the scope of specifying LAC or pairing system message 1 label value of RAC, after the database change is finished, sends message informing OMC.
OMC is by the message informing foreground, the foreground is according to the scope of the label value of the pairing system message 1 in all sub-districts in content update LAC in the OMC message or the RAC scope, revise the label value of system message simultaneously, each sub-district all needs the transmitting system information updating to NODEB, requires NODEB that the updated system messages content is broadcasted in whole sub-district.
Specify the label value configuring condition of system message 1 according to Fig. 2, we can see three LAC, sub-district C0, C1, C2, C3 are wherein arranged among the LAC1, C0 wherein and C1 are the PS sub-districts, C2 and C3 are the CS sub-districts, it all is the CS sub-district that sub-district C4, C5 are arranged among the LAC2, and it also all is the CS sub-district that sub-district C7, C8 are arranged among the LAC3.Just can followingly plan in the network planning: the label value scope of the system message 1 of LAC1 correspondence is (1～10), and the label value scope of LAC2 is (11～20), and the label value scope of LAC3 is (21～30).And two RAC in LAC1 that need dispose be different with label value LAC1, but can be with LAC2 and LAC3 identical, can be configured to RAC1 (11～15), RAC2 is (16～22) etc.The words of configuration like this, according to cell configuration minimality principle, the scope that is in system message 1 label value of the CS territory sub-district C2 among the LAC1 can only change in (1～10), and the label value scope of PS territory sub-district C0 is (11～16), and the label value scope of C1 is (16～22); The label value scope that is in two CS territory sub-district C4, C5 among the LAC2 is (11～20), and the label value scope that is in C6, the C7 of the sub-district, CS territory among the LAC3 is (21～30).
So according to this detailed planning mode, move to the sub-district among the LAC2 or move to sub-district among the LAC3 no matter UE is the sub-district from LAC1, no matter also UE is from RAC1 to RAC2, more no matter UE moves between from RAC1 to LAC1, the label value of all original cell and Target cell all is different, like this UE or initiate position and upgrade or can initiate Routing Area Update one time.
The present invention can be so that adjacent and be in the sub-district of Different L AC or RAC, the label value of its system message 1 is identical never, so just guaranteed that UE is between the neighbor cell that belongs to Different L AC or RAC when mobile, content in success will follow the read system message 1, thus the completing place is upgraded or routing update smoothly.
Can offer user (perhaps customer service personnel) according to the network planning, be the label value scope of the different system message 1 of each LAC or RAC configuration, guarantee to have identical system message 1 label value scope in the sub-district of same LAC or RAC inside.In order to make full use of the scope of system message 1 label value, also can be non-conterminous LAC or the identical label value scope of RAC configuration according to planning.
Can also provide scope to dynamically update at system message 1 label value of LAC or RAC correspondence, such as the beginning planning process in the success distributed different label value scopes at LAC or RAC, but may have two or more adjacent LAC, RAC in the time of dilatation afterwards or deletion LAC or RAC and the overlapping part of label value scope occur, in order not influence normal operation, dynamically change the scope of the label value of these LAC or RAC correspondence by the Operation and Maintenance platform.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
