Embodiment two
Present embodiment is that executive agent is set forth location updating method with the travelling carriage, is elaborated below in conjunction with accompanying drawing, and referring to Fig. 2, this method may further comprise the steps:
Step 201: travelling carriage obtains the paging group sign bitmap of the regular length of base station transmission;
The method that travelling carriage obtains the paging group sign bitmap of regular length can have dual mode:
Travelling carriage obtains the paging group sign bitmap that the affiliated complete paging group in base station identifies one regular length in the bitmap that is mapped to presetting length.
Travelling carriage obtains by presetting figure place and according to prerequisite the paging group that the paging group under base station sign is mapped to the regular length that the bitmap of presetting length forms being identified bitmap, presets figure place before the bitmap of presetting length, and prerequisite is with to preset figure place corresponding.
The mode of the paging group sign bitmap of travelling carriage reception regular length is corresponding with the send mode among the embodiment one, repeats no more herein.

Embodiment two is position method for updating of setting forth from mobile station side, and the various combination form according to paging group sign bitmap has provided corresponding embodiment below.
Embodiment three
Present embodiment is that the sign of the complete paging group under the base station is mapped to a bit position method for updating in the bitmap of presetting length, is elaborated below in conjunction with accompanying drawing.Referring to Fig. 3, the method for present embodiment may further comprise the steps:
Step 301: the sign of the complete paging group under the base station is mapped in the bitmap of presetting length, is fixed the paging group sign bitmap of length, send the paging group sign bitmap of regular length to travelling carriage;
For example, referring to Fig. 4, defining the bitmap of a fixed length, for example can be 16 bitmap, by certain mapping ruler, such as hashing algorithm, the complete paging group sign under the base station is mapped to a certain position of bitmap.Belong to paging group 5 such as a base station, 7, paging group 5 and 7 all is mapped to the 0th of bitmap, the bitmap of its transmission is ' 1000000000000000 ' so, promptly need with paging group sign equal 5 and the paging group sign equal 7 pairing figure places and put 1, i.e. the 0th position 1, if having done in paging group 1 originally, a travelling carriage moved to this base station after the position is upgraded, paging group 1 is mapped to the 1st of bitmap, travelling carriage can find the figure place of paging group 1 correspondence according to known algorithm so, promptly the 1st, travelling carriage is found the 1st position 0 then, represent that then this base station does not belong to paging group 1, travelling carriage just should be initiated the position immediately and upgraded so, because travelling carriage was judged paging group variation was taken place this moment.
Above mapping ruler is that base station and travelling carriage are known, such as being the known mapping ruler that the whole network is unified or agreement is stipulated.Concrete mapping ruler can be a hashing algorithm, such as a definition hash function y=f (x), wherein imports x and be the paging group sign of base station, and the y figure place that to be paging group identify in the corresponding bitmap.Above-mentioned mapping ruler can also be a modulo operation, such as y=xmod16, adopts this mapping ruler also can find paging group to identify figure place in the corresponding bitmap.
Base station definition paging indication bitmap, this paging indication bitmap is corresponding to the pairing paging group in position of above-mentioned paging group sign bitmap mid-1, whether and identifying these paging groups has paging to send, referring to Fig. 5, for example a base station belongs to paging group 5,7, paging group 5 and 7 all is mapped to the 0th of paging group sign bitmap, the paging group of regular length sign bitmap is ' 1000000000000000 ' so, can paging indicate bitmap to be set to ' 1000000000000000 ', these paging groups of then representing the 0th correspondence have paging to send, be paging group 5 and 7, if paging group 5 has paging to send, a travelling carriage belongs to paging group 5, and according to the indication of paging indication bitmap, travelling carriage just should follow-uply go paging receiving message so.
Paging indication bitmap also can be set to distance to go, promptly corresponding to ' 1 ' number in the paging group sign bitmap, promptly has how many positions to be changed to 1, sends for whether the corresponding paging groups in ' 1 ' position have paging corresponding to these successively.Referring to Fig. 6, for example, paging group sign bitmap is ' 1010000000000000 ', can paging indicate bitmap to be set to ' 11 ', then first is ' 1 ' corresponding to the 0th in the paging group sign bitmap in the paging indication bitmap, and in the paging indication bitmap second ' 1 ' is corresponding to the 2nd in the paging group sign bitmap.If the paging group sign bitmap of base station definition is other situation, each implication of ' 1 ' by that analogy in the paging indication bitmap that is provided with so.In the paging indication bitmap each can be changed to 0 or be changed to 1, being changed to 1 corresponding paging group of expression has paging to need to send, travelling carriage needs follow-up continuation paging receiving message, and the paging group that is changed to 0 this correspondence of expression does not have paging to send, and travelling carriage can keep idle condition.
Can be placed in the broadcast channel in the superframe head according to the good paging group of above rule definition sign bitmap and paging indication bitmap and to send, further, can be placed in basic broadcast channel or the additional broadcast channel and send.
Because the broadcast channel transmission cycle in the superframe head is short, so travelling carriage can receive this bitmap timely, thereby finds timely whether paging group changes, upgrade thereby can determine whether to initiate the position.In addition, when travelling carriage has been judged paging group and has been changed, travelling carriage needn't be opened receiver and continue to wait for the paging group sign that comprises in the broadcast parameter that sends on the ordinary data channel, travelling carriage can power saving like this, simultaneously, because the length of bitmap is fixed, can not increase the complexity of broadcast channel design.
Step 302 is identical with step 102, repeats no more herein.
When travelling carriage is executive agent, also can realize said method, this moment is similar with embodiment two, repeats no more herein.
Present embodiment identifies bitmap by one paging group in the bitmap that sends the corresponding regular length of each paging group to travelling carriage, can reduce the base station and use extra Length Indication to carry several paging groups signs, and then can reduce the control expense.Further, send the paging group sign bitmap of regular length by superframe head or superframe head broadcast channel, send little at interval, can make travelling carriage find that in time paging group changes, thereby trigger position upgrades timely, and receive dynamic content dispensing message because travelling carriage need not be opened receiver always, can save the energy of travelling carriage, also reduce the expense of broadcast channel as much as possible.
Further, because paging indication bitmap indicates whether that paging is arranged, can allow the timely paging receiving of travelling carriage.
Embodiment three has set forth the sign of the complete paging group under the base station has been mapped to a bit position method for updating in the bitmap of presetting length, set forth a kind of before the bitmap of presetting length, increasing below and preset figure place, according to prerequisite paging group is identified the bitmap that is mapped to presetting length, to realize the position method for updating.
Embodiment four
Present embodiment increases before the bitmap of presetting length and presets figure place, the sign of the paging group under the base station is mapped to the bitmap of presetting length according to prerequisite, it is corresponding with prerequisite to preset figure place, the paging group sign bitmap of the regular length that the bitmap that presets figure place and presetting length is formed sends to travelling carriage, to realize the position method for updating, be elaborated below in conjunction with accompanying drawing, referring to Fig. 7, the method for present embodiment may further comprise the steps:
Step 501: before the bitmap of presetting length, increase and preset figure place, the sign of the paging group under the base station is mapped to the bitmap of presetting length according to prerequisite, it is corresponding with prerequisite to preset figure place, and the paging group sign bitmap of the regular length that the bitmap that presets figure place and presetting length is formed sends to travelling carriage;
If the chance that base station belongs to a plurality of paging groups simultaneously is little, even perhaps a base station belongs to a plurality of paging groups simultaneously, but the quantity of paging group also is limited several, therefore can adopt in the increase of the bitmap front of presetting length and preset figure place, according to prerequisite the paging group under base station sign is mapped to the bitmap of presetting length, the paging group sign bitmap of the regular length that the bitmap that presets figure place and presetting length is formed sends to travelling carriage.
For example, referring to Fig. 8, can be to increase by two in the bitmap front, to several combinations of two regulations of this increase, be 00 o'clock such as front two, what expression was carried later is a complete paging group sign, and this base station only belongs to a paging group; If front two is 01 o'clock, what then represent to carry later is two paging groups signs through overcompression, and this base station belongs to two paging groups simultaneously, paging group sign through overcompression of wherein per eight bit representations.Concrete compression algorithm can adopt certain mapping ruler, hashing algorithm for example, the paging group of sixteen bit sign hashed to the paging group sign after eight the compression, mapping ruler also can be exactly simple intercept operation, such as the high eight-bit of getting complete paging group sign or low eight.When front two was 11, then each paging group is corresponding one, and was identical with situation shown in Figure 4.
Base station definition paging indication bitmap, each in the paging indication bitmap is corresponding to the front two in the paging group sign bitmap.For example, referring to Fig. 9, when the front two of paging indication bitmap is 00, this moment, the paging group sign bitmap of regular length represented only to belong to a paging group, paging indication bitmap has only one so, whether the paging group of expression paging group sign bitmap correspondence has paging to send, and promptly this position is that the paging group of representing paging group sign bitmap correspondence at 0 o'clock does not have paging to send, and this position is that the paging group of representing paging group sign bitmap correspondence at 1 o'clock has paging to send; When the front two of paging group sign bitmap is 01, this moment, paging group sign bitmap represented to belong to simultaneously two paging groups, paging indication bitmap has two so, whether the paging group of representing the first and second part correspondences of paging group sign bitmap respectively has paging to send, being changed to the paging group of representing paging group sign bitmap correspondence at 0 o'clock does not have paging to send, and being changed to the paging group of representing paging group sign bitmap correspondence at 1 o'clock has paging to send.If the front two of the paging group of base station definition sign bitmap is other situation, the figure place of the paging indication bitmap that is provided with so and wherein each implication of ' 1 ' is by that analogy.
The base station will be put into broadcast channel according to the paging group sign bitmap of above rule assembling and paging indication bitmap and send, and also can adopt other send mode identical with embodiment one, repeat no more herein.
Step 502 is identical with step 102, repeats no more herein.
When travelling carriage is executive agent, also can realize said method, this moment is similar with embodiment two, repeats no more herein.
Present embodiment presets figure place by increasing before the bitmap of presetting length, the sign of the paging group under the base station is mapped to the bitmap of presetting length according to prerequisite, it is corresponding with prerequisite to preset figure place, the paging group sign bitmap of the regular length that the bitmap that presets figure place and presetting length is formed sends to travelling carriage, can reduce the base station and use extra Length Indication to carry several paging group signs, and then can reduce the control expense.Further, send the paging group sign bitmap of regular length by superframe head or superframe head broadcast channel, send little at interval, can make travelling carriage find that in time paging group changes, thereby trigger position upgrades timely, and receive dynamic content dispensing message because travelling carriage need not be opened receiver always, can save the energy of travelling carriage, also reduce the expense of broadcast channel as much as possible.Simultaneously, the different paging group of minimizing that can also be suitable is mapped to the situation of the identical figure place of paging group sign bitmap, and present embodiment can carry more figure place and come corresponding paging group.
Further, because paging indication bitmap indicates whether that paging is arranged, can allow the timely paging receiving of travelling carriage.
The paging indication bitmap of setting forth among the embodiment four is elongated, sets forth the embodiment that travelling carriage receives a kind of compress bitmap of the regular length that comprises paging group sign bitmap and paging indication bitmap below.
Embodiment five
Present embodiment is set forth after a kind of travelling carriage receives paging group sign bitmap, judge according to paging group sign bitmap whether paging group changes, send change if judge paging group, then initiate the position and upgrade,, then judged whether beep-page message according to the paging indication bitmap that receives if judge that paging group does not change, if beep-page message is arranged, then continue to receive follow-up beep-page message, if there is not beep-page message, travelling carriage is directly return idle condition.
At first, travelling carriage judges according to the paging group sign bitmap that receives whether paging group sends change, if paging group changes, handling process is with the step 203 among the embodiment two, if paging group does not send change, then judges according to the paging indication bitmap that receives whether corresponding paging group has paging to send, if there is paging to send, then travelling carriage continues to receive follow-up beep-page message, otherwise travelling carriage is directly return idle condition.
Referring to Figure 10, this method may further comprise the steps:
Step 1: travelling carriage obtains the paging group sign bitmap of regular length;
Step 2: travelling carriage judges whether to move to new paging group according to the paging group sign bitmap of regular length;
Step 3: when the travelling carriage judgement moves to new paging group, send position updating request to the base station;
Step 4: when the travelling carriage judgement does not move to new paging group, judge according to the paging indication bitmap that gets access to whether the paging group of the paging group sign bitmap correspondence of regular length has paging to send;
Step 5: if travelling carriage judges that according to paging indication bitmap the paging group of the paging group sign bitmap correspondence of regular length has paging to send travelling carriage paging receiving message;
Step 6: if travelling carriage judges that according to paging indication bitmap the paging group of the paging group sign bitmap correspondence of regular length does not have paging to send, travelling carriage is got back to idle condition.
The paging group indication bitmap that receives can be the regular length of separating with paging group sign bitmap or the bitmap of variation length, paging indication bitmap can be the pairing paging group in position corresponding to paging group sign bitmap mid-1, also can be corresponding to ' 1 ' number in the paging group sign bitmap, can also be corresponding to the front two in the paging group sign bitmap, draw in the paging group sign bitmap according to the prerequisite of front two correspondence and include the length that several paging groups are determined paging indication bitmap.
The paging indication bitmap that receives also can be the compress bitmap that identifies the regular length of bitmap composition with paging group, referring to Figure 11, the compress bitmap of regular length is divided into three parts, first is the front two of this compress bitmap, several combinations of these two regulations, be used for representing that it carries later is several paging groups signs, and second portion is the paging group sign bitmap of compression, this part length changes, according to the indication of first, for example, when first is 00, the paging group sign bitmap of compression is 15, and when first was 01, the paging group of compression sign bitmap was 14, and each 7 of front and back, represent two paging groups, when first is other form, the length of the paging group of compression sign bitmap and the like.Third part is a paging indication bitmap, this part also is to indicate according to first, length also can change, for example when first is 00, paging indication bitmap has only one, when first was 01, paging indication bitmap had two, and whether the paging group of the paging group sign bitmap correspondence of expression second portion has paging to send.
For example, when first was 00, the expression base station only belonged to a paging group, and then 15 paging group sign bitmap is represented the paging group that the base station is affiliated, and one paging indicating bit figure represents whether corresponding this paging group has paging to send; When first is 10, represent that then the base station belongs to 4 paging groups, 3 three paging group sign bitmap is represented the paging group under the base station, and 4 paging indication bitmap corresponds respectively to this 4 paging groups, and whether the paging group under the expression has paging to send respectively.
Length according to the new compress bitmap of this rule assembling is fixed, and also can allow the timely paging receiving of travelling carriage, has reduced sending the expense of paging indication, and has been easy to design more.
