Abstract
The present invention discloses a method for setting a value label for a system information block type 1 (SIB1) of a cell broadcast. The value label range of SIB1 is divided into non-void subsets which are pairwise and mutually exclusive; the subsets are allocated to different routing regions to make adjacent routing regions correspond to different subsets during planning a network. The value label of SIB1 has different values within the corresponding subset range of the affiliated routing regions of the cell when SIB1 is updated. The present invention ensures that different SIB1 value labels can always be detected to further read SIBl when user equipment (UE) moves in different routing regions. The present invention has new triggered positions, and avoids the situation that the communication network can not call UE.
Description
Technical field
The present invention relates to the information discriminating technology of Wideband Code Division Multiple Access (WCDMA) (WCDMA) connecting system, be specifically related to the method to set up of a kind of cell broadcasting system type of information block 1 (SIB1) value label.
Background technology
Stipulate according to the WCDMA agreement, cell broadcasting system information is transmitted by cell broadcasting system block of information (SIB), SIB is divided into Scheduling Block (SB), type of information block 1 (SIB1), type of information block 2 (SIB2), type of information block 3 (SIB3) or the like according to its logic function, wherein mainly deposit the information of core net (CN) and the timer of subscriber equipment (UE) among the SIB1, it has comprised with the UE position upgrades relevant information.Block of informations such as SIB1, SIB2, SIB3 logically transmit respectively, and UE determines respectively according to their value labels separately whether corresponding system information changes.In actual applications, the value label is equivalent to the version number of information, the renewal degree of its expression current information, and the either field of SIB changes, and the value label will correspondingly change, and SIB upgrades with expression.In the WCDMA system, the value label of SIB is deposited among Master Information Block (MIB) and this SIB, when UE when current channel reads information, read MIB earlier, therefrom check the value label of each SIB, then relatively with the respective value label preserved among itself and the UE, if comparative result equates, show that UE has obtained up-to-date SIB, needn't remove to read this SIB again; Otherwise, if comparative result is unequal, showing that this SIB is new system information, UE need read this SIB again, and preserves new SIB information and new value label after obtaining new SIB.
The value label of SIB is divided into two classes according to effective range in the WCDMA system at present: public land mobile communication network (PLMN) and sub-district (Cell).UE carries out following processing respectively to the SIB that adopts these two kinds of method classification:
1, value label effective range be the situation of Cell: UE when entering another sub-district, if do not store the SIB of this sub-district correspondence before this, just read the SIB of current area again; If stored the SIB of this sub-district correspondence before this, then need the value label of the SIB of this Cell Broadcast CB relatively and this sub-district respective value label of being stored, if both equate, needn't read again, otherwise need read the SIB of this Cell Broadcast CB again.
2, value label effective range be the situation of PLMN: UE when entering another sub-district, only need the value label and the value label of having stored of SIB correspondence in this sub-district relatively, if both do not wait, then need to read again; If both equate, needn't read again.
According to WCDMA agreement regulation, the value label effective range of SIB1 can only be PLMN, and the value label effective range of other SIB is Cell.Do not gather division in present effective range for the value label of SIB1, but the value label of each sub-district is all chosen in this effective range, its choosing method has multiple, random value for example, perhaps it is worth label forward sequence value in the PLMN scope when SIB1 upgrades, if last value is then got first.But adopt any obtaining value method no matter be in the prior art, they all do not have the span of SIB1 value label in each sub-district is demarcated, but all in whole PLMN scope, choose, the situation that the value label of SIB1 in the sub-district in adjacent route district equates so just might appear.UE can think that this value label does not change, thereby no longer read SIB1 when moving to the new sub-district in adjacent route district so.In WCDMA, UE is that circuit domain or packet domain are carried out different position renewals according to its registration, the position renewal that is registered as the UE of circuit domain is carried out based on different lane place, and the position that is registered as the UE of packet domain is upgraded based on carrying out in different route districts, lane place and route district all are position ranges, their relation is a tree, and promptly a lane place comprises several route districts, and a route district only belongs to a lane place.Because in WCDMA, UE is registration circuit territory and packet domain simultaneously generally, and the position of UE more is based on that the route district carries out in new capital like this.Therefore, if UE thinks that the value label of SIB1 does not have to change and no longer reads new SIB1, UE can't know and enter new route district that the position updating process that should trigger can not start.Because UE is based on the route district paging receiving of its current registration under the paging idle condition, so in these cases, communication network will be at former registration route district's paging UE, and this will cause normally paging receiving of UE.
In order to address this problem, promptly SIB1 upgrades its value label of back and but equates and cause the UE can not the enable position renewal and then normal paging receiving, has proposed two kinds of solutions at present:
Whether scheme 1, change the validity scope of SIB1 value label into Cell, UE reads SIB1 in new sub-district, and whether the value label that only need compare both when resting on this sub-district is identical, determine reading of content then the problems referred to above can not occur on this comparison basis.But this scheme will cause revising the 3rd third-generation mobile communication (3GPP) agreement, and will be relatively more difficult in realization.In addition, this scheme also will cause UE frequently to read identical SIB1, and for example UE moves in same route district, and SIB1 equates just in this route district, will make relative efficiency lower like this.
Scheme 2, employing network plan method are the different value label of sub-district fixed allocation value in the adjacent route district when cell initial is set up, but will cause SIB1 to upgrade like this, because the SIB1 of each sub-district has only a unique changeless value label, even universal mobile telecommunications system land radio access web (UTRAN) has upgraded SIB1, because its value label does not change, UE also is unable to find out the variation of self-position, can cause equally can't the trigger position renewal process, to such an extent as to ICQ takes place less than the situation of UE.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of method to set up of Cell Broadcast CB SIB1 value label is provided, it does not wait the SIB1 value label of the neighbor cell that belongs to different routes district, and each sub-district SIB1 can change its value label when upgrading.
The object of the invention is achieved by following technical proposals:
The codomain of SIB1 value label is divided into more than or equal to 4 subclass, and makes each subclass comprise two values at least, and the value that all subclass comprise is different in twos; Be that adjacent route district distributes different subclass when the network planning; When SIB1 changes, in all elements that subclass comprised that distributes for this route district, select another value that is different from currency, and give type of information block 1 as the value label distribution selected another value.
In the process that dividing subset is closed, the element number in each subclass can equate, and is that the element number of each subclass is more than or equal to 8 and be less than or equal to 64 best.In value label obtaining value method, can make the value chance of each element in the subclass impartial on statistical significance, and be order value forward or backwards best.
Compared with prior art, SIB1 value label setting method provided by the present invention is divided into different non-empty subsets by the codomain with SIB1, and make adjacent route district use different subclass by network plan method, SIB1 its value label variations scope when upgrading only is confined to avoid adjacent route in-zone cell SIB1 content difference and the identical situation of value label in the subclass of self route district correspondence.UE when mobile, will inevitably find that the value label of SIB1 changes, and then read SIB1 again between these route districts, learn to enter another route district, the trigger position renewal process, thus avoided network in the prior art may paging less than the situation of UE.
