Abstract
The invention provides a paging method, comprising: determining a paging range related to a terminal according to information related to the cell in which the terminal needed to page may be located; paging the determined paging range; and expanding the paging range or ending it up if the paging is invalid. In the invention, the one firstly paged is just the paging range related to the terminal as users using the terminal have everyday moving ranges which are basically limited, or users using the terminal basically move within a cell or an adjacent one. The successful probability of one-time paging is bigger if the paging range related to the terminal is firstly paged in this instance so as to prevent from packing other unrelated cells and save bear resource.
Description
Technical field
The present invention relates to the communication technology, relate in particular to paging technique.
Background technology
When the paging center paging is called, need know the position at called place, otherwise, if the paging that requirement once just can be successful just must be carried out the whole network paging to called.For example, in global system for mobile communications (GSM, Global System for Mobile communication), have a lot of sub-districts under the mobile switching centre (MSC, mobile switching centre).When MSC wants call terminal, need know the position at the present place of terminal equally, if do not know the position at terminal place, paging just has only paging is carried out in all sub-districts under the MSC to terminal again.But the paging range that this paging method relates to is too big, and the interface-free resources that causes paging to take is very big.
At present, for avoiding when the paging, under the MSC all can be distinguished into several lane place for a short time to a large amount of the taking of interface-free resources, each lane place has comprised a plurality of sub-districts, like this, and when terminal changes in the position, for example during cell update, whether the new sub-district after judgement is upgraded is in new lane place, if then initiate more new technological process of position, promptly, with new location information notification to MSC, otherwise, do not initiate more new technological process of position.In this case, if when MSC does not obtain the accurate location information of terminal and needs call terminal, only all sub-districts that need comprise the lane place at this terminal place are carried out paging and are got final product.With respect to the mode of all sub-districts under the paging MSC, saved interface-free resources to a certain extent.But, because the quantity of the sub-district that comprises, each lane place is still very big, so MSC when paging is carried out in all sub-districts that the lane place is comprised, still can take many interface-free resources under the condition of the accurate location information that does not obtain terminal.If in busy period of communication, a paging will take a lot of interface-free resources, just may cause some paging to be delayed or fail.
Summary of the invention
The technical problem that the present invention will solve is to provide a kind of paging method and device, takies less under the prerequisite of interface-free resources to be implemented in as far as possible, and terminal is carried out paging.
The invention provides a kind of embodiment of paging method, comprising: according to the terminal of needs paging current may the place relevant information of sub-district, determine the paging range relevant with described terminal; To described definite paging range paging; If paging failure then enlarges paging range or finishes paging.
The invention provides a kind of embodiment of paging equipment, comprising: the paging range determining unit, according to the terminal of needs paging current may the place relevant information of sub-district, be used for determining the paging range relevant with described terminal; Paging unit is used for described definite paging range paging, if paging failure then enlarges paging range or finishes paging.
In above-mentioned all embodiment, at first paging is the paging range relevant with terminal, because using the scope of user's activity every day of terminal all is limited basically, in other words, use the user of terminal all movable in a sub-district or neighbor cell basically every day, in this case, if the paging paging range relevant at first with described terminal, then the probability of a paging success can be bigger, and then avoid the paging to other irrelevant sub-districts, therefore can save interface-free resources.

Embodiment
At first the overall technical architecture to a kind of paging method embodiment provided by the invention describes.This method embodiment comprises: according to the terminal of needs paging current may the place relevant information of sub-district, determine the paging range relevant with described terminal; To described definite paging range paging; If paging failure then enlarges paging range or finishes paging.
The paging range relevant with terminal here can be the sub-district at the current possibility of terminal place, the cell information at the current possibility of terminal place can be original information of preserving, also can be the raw information that obtains, can also be the information of inferring out through the raw information of original information of preserving and/or acquisition; The paging range relevant with terminal can also be sub-district and at least one neighbor cell at the current possibility of terminal place, certainly, the cell information at the current possibility of terminal place and at least one adjacent cell information also can be original information of preserving, can also be the raw information that obtains, can also be the information of inferring out through the raw information of original information of preserving and/or acquisition.
If, can select to enlarge paging range, certainly, also can finish paging to the paging range paging failure relevant with terminal.
In addition, that make a call can be MSC, also can be the base station controller (BSC, Base Station Controller) under the MSC, can also be base transceiver station or base station (BTS, BaseTransceiver Station) under the BSC.
Below in conjunction with several preferred embodiments, embodiment is elaborated to said method.
Fig. 1 is the flow chart of first preferred embodiment of the inventive method.As shown in Figure 1, comprising:
The step S101:MSC couple of BSC relevant with the terminal that needs paging carries out paging.
Preserve the relevant information of sub-district, the current possibility place of terminal among the MSC, the relevant information here can be terminal current may the place sign CI, overall identification CGI, the terminal of sub-district current BSC information (for example numbering) and the current BTS information (for example numbering) that may sub-district, place correspondence of terminal that may sub-district, place correspondence, can also be terminal current may the sub-district, place sign CI and the sign of neighbor cell.MSC can obtain above-mentioned relevant information when terminal is initiated position updating request, can also obtain above-mentioned information when page response before.
MSC can determine the BSC relevant with terminal according to above-mentioned relevant information, and then initiates paging to BSC.Further, when MSC initiates paging to BSC, above-mentioned relevant information can be offered BSC.Certainly, if BSC has also preserved or the above-mentioned relevant information of acquisition of having the ability, then MSC can offer BSC with above-mentioned relevant information.
Step S102:BSC carries out paging to the sub-district at the current possibility of terminal place.
BSC can obtain and preserve the relevant information of sub-district, the current possibility place of terminal in terminal when MSC initiates position updating request, also can receive the above-mentioned relevant information that MSC sends.BSC can be according to these information, paging is carried out in all sub-districts of oneself controlling, also can carry out paging by a BTS to sub-district, the current possibility place of terminal correspondence, after BTS receives beep-page message, can carry out paging to all sub-districts of oneself controlling, also can only carry out paging the sub-district at the current possibility of terminal place.
Step S103:MSC judges in the default time whether receive page response, if, carry out subsequent treatment, otherwise, step S104 changeed.
Step S104: enlarge paging range or finish paging.
Enlarge paging range a variety of modes are arranged, for example, can carry out paging to other sub-districts except that sub-district, the current possibility place of terminal in the lane place, also can carry out paging to all sub-districts in the lane place, can also to terminal current may the place at least one neighbor cell of sub-district carry out paging, even can also to terminal may be movable other sub-districts or current be not that very busy neighbor cell carries out paging.
If MSC need carry out paging at least one neighbor cell of sub-district, the current possibility place of terminal, then MSC can determine that needs carry out paging to which or which neighbor cell according to the relevant information of preservation or sub-district, the current possibility place of acquisition terminal, may be that a part of neighbor cell is carried out paging, also might be that all neighbor cells are carried out paging.The mode of paging has a variety of, for example, MSC can carry out paging to the BSC of neighbor cell correspondence, after BSC receives beep-page message, can carry out paging to all sub-districts of oneself controlling, can also carry out paging to the BTS of neighbor cell correspondence, BTS can carry out paging to all sub-districts of oneself controlling, can also only carry out paging to neighbor cell.Need to prove, the sub-district at the current possibility of terminal place and neighbor cell may coexist under a BSC or the BTS, also may not coexist under a BSC or the BTS, if do not coexist under BSC or the BTS, then MSC can need the different B SC of the neighbor cell correspondence of paging to carry out paging to all respectively, also can select one of them or several BSC of the neighbor cell correspondence of paging that needs to carry out paging, in like manner, BSC also can need the different B TS of the neighbor cell correspondence of paging to carry out paging to all respectively, also can select one of them or several BTS of the neighbor cell correspondence of paging that needs to carry out paging.
For the situation that MSC carries out paging to other movable sub-districts of terminal possibility, MSC can determine that terminal may other movable sub-districts according to the activation record before the terminal.The mode that realizes has a variety of, a kind of implementation wherein is, MSC can preserve or obtain the record of end activity, for example terminal is through being everlasting which or which sub-district activity, in the time of needs, MSC just can determine other movable sub-districts of terminal possibility according to these records, and then decision is once more to which cell paging.
Need to prove that step S103 has a variety of implementations, a variety of replacement schemes are also arranged.For example, BSC can judge in the default time whether receive page response, if, then MSC is returned page response, otherwise, also to notify MSC not receive page response.The result that MSC can return according to BSC determines whether to receive page response, if, carry out subsequent treatment, otherwise, step S104 changeed.Again for example, if BTS has participated in calling, then BTS also can judge in the default time whether receive page response, if, then BSC is returned page response, otherwise, also to notify BSC not receive page response.The result that BSC can return according to BTS determines whether to receive page response, and then whether decision reports the paging result to MSC again.Certainly, the paging result that MSC or BSC can also return according to BSC or BTS in conjunction with the default time, takes all factors into consideration and whether can receive page response again.
In above-mentioned first preferred embodiment, MSC at first paging be the current sub-district that may the place of terminal.Owing to use the user of terminal in most of times, all can be in the relatively-stationary sub-district, and the location update message that terminal is regularly sent can in time be notified MSC oneself sub-district at current place, so, generally speaking, call terminal current may the place the sub-district basically all can be successful paging to terminal, like this with regard to solved MSC start large-scale at the lane place paging and the problem that takies a large amount of interface-free resources that causes.
In practice, terminal may be in the border of two sub-districts for a long time, and might switch back and forth between two sub-districts on the border of being everlasting, if for guaranteeing just success of paging for the first time, can be when first time paging, carry out paging at terminal current sub-district and neighbor cell that may the place.For this reason, the invention provides one second preferred embodiment.
Fig. 2 is the flow chart of second preferred embodiment of the inventive method.As shown in Figure 2, comprising:
Step S201:MSC as required the terminal of paging current may the sub-district, place information and the information of neighbor cell, relevant BSC is carried out paging.
MSC can preserve or obtain the relevant information of sub-district, the current possibility place of terminal, the relevant information here can be terminal current may the place sign CI, overall identification CGI, the terminal of sub-district current BSC information (for example numbering) and the current BTS information (for example numbering) that may sub-district, place correspondence of terminal that may sub-district, place correspondence, can also be the sign of neighbor cell.Concrete, MSC can also preserve or obtain the information table of each sub-district and neighbor cell thereof.MSC can obtain above-mentioned relevant information when terminal is initiated position updating request, can also obtain above-mentioned information when page response before.
MSC can determine relevant BSC according to above-mentioned relevant information, and then initiates paging to BSC.Further, when MSC initiates paging to BSC, above-mentioned relevant information can be offered BSC.Certainly, if BSC has also preserved or the above-mentioned relevant information of acquisition of having the ability, then MSC can offer BSC with above-mentioned relevant information.
In addition, the current sub-district that may the place of terminal may corresponding same BSC with neighbor cell, also may corresponding different BSC, and further, the corresponding same BSC of these neighbor cells possibilities, also possible corresponding different BSC is so MSC determines that needing the BSC of paging may be one, also may be a plurality of, therefore, the BSC of MSC paging may be one, also may be a plurality of.
Step S202:BSC carries out paging to the sub-district and/or the neighbor cell at the current possibility of terminal place.
Mention in step S201, BSC can preserve or obtain the relevant information of sub-district, the current possibility place of terminal, also can receive the above-mentioned relevant information that MSC provides.BSC can carry out paging to all sub-districts of oneself controlling according to these information, also can carry out paging by a BTS to terminal current possibility sub-district, place and/or neighbor cell correspondence.Need to prove, if terminal current possibility sub-district, place and neighbor cell do not coexist under the BSC, then the BSC of MSC paging has a plurality of, after these BSC receive beep-page message, need carry out paging to the terminal of oneself controlling current possibility sub-district, place and/or neighbor cell, because the sub-district at the current possibility of the BSC control terminal that has place, even also control one or more neighbor cells, so can call terminal current sub-district that may the place of this BSC, even can also the one or more neighbor cells of paging, because the BSC that has is sub-district, the current possibility place of control terminal not, and only control one or more neighbor cells, so this BSC can only paging the neighbor cell of control.If BSC carries out paging to the BTS of terminal current possibility sub-district, place and/or neighbor cell correspondence, after then BTS receives beep-page message, can carry out paging to all sub-districts of oneself controlling, also can only carry out paging terminal current possibility sub-district, place and/or neighbor cell.
Step S203:MSC judges in the default time whether receive page response, if, carry out subsequent treatment, otherwise, step S204 changeed.
Step S204: enlarge paging range or finish paging.
Enlarge paging range a variety of modes are arranged, for example, can carry out paging to other sub-districts except that terminal current possibility sub-district, place and neighbor cell in the lane place, also can carry out paging to all sub-districts in the lane place, can also carry out paging to the sub-district adjacent with neighbor cell, in addition can also to terminal may be movable other sub-districts or current be not that very busy neighbor cell carries out paging.
Need to prove that step S203 has a variety of implementations, a variety of replacement schemes are also arranged.For example, BSC can judge in the default time whether receive page response, if, then MSC is returned page response, otherwise, also to notify MSC not receive page response.The result that MSC can return according to BSC determines whether to receive page response, if, carry out subsequent treatment, otherwise, step S204 changeed.Again for example, if BTS has participated in calling, then BTS also can judge in the default time whether receive page response, if, then BSC is returned page response, otherwise, also to notify BSC not receive page response.The result that BSC can return according to BTS determines whether to receive page response, and then whether decision reports the paging result to MSC again.Certainly, the paging result that MSC or BSC can also return according to BSC or BTS in conjunction with the default time, takes all factors into consideration and whether can receive page response again.
In above-mentioned second preferred embodiment, MSC at first paging be current sub-district and neighbor cell that may the place of terminal.Because most of time of user can not left the zone that a sub-district and neighbor cell are formed, so second preferred embodiment can guarantee to a great extent that also paging for the first time can success.
In above-mentioned second preferred embodiment, when terminal current may the sub-district, place and neighbor cell all be in BSC following time, MSC can only need to preserve the current sign that may the sub-district, place of terminal and get final product, and does not need to preserve the sign of its neighbor cell again.Promptly, when terminal is initiated the position renewal, BSC does not need to send the adjacent cell information of sub-district, the current possibility place of terminal to MSC yet, but only with terminal current may the place identification information of sub-district send MSC to and preserve, like this, when MSC initiated paging, BSC was after obtaining the beep-page message of MSC, can obtain the information of neighbor cell according to the cell identity information in the beep-page message, so to terminal current may the sub-district, place and neighbor cell carry out paging and get final product.Obviously, this processing mode can be saved signal resource.
In above-mentioned second preferred embodiment, MSC to terminal current may the place BSC of sub-district correspondence when initiating paging, can only the identification information of sub-district, the current possibility place of terminal be offered the BSC of correspondence, and to terminal current may the place BSC of neighbor cell correspondence of sub-district when sending beep-page message, can only the identification information of neighbor cell be offered the BSC of correspondence, like this, the BSC of sub-district, the current possibility place of terminal correspondence can be according to the identification information of sub-district, the current possibility place of the terminal that obtains, obtain the identification information of neighbor cell, and then to terminal current may the sub-district, place and neighbor cell carry out paging, and those not to be terminal current may sub-district, place correspondence BSC when getting access to cell information, can directly carry out paging and get final product this sub-district.In addition, whether MSC sends to and may further include one in the beep-page message of BSC is the sign of the current BSC that may sub-district, place correspondence of terminal, judges to help BSC.For example, BSC can judge according to sign whether oneself is the BSC of sub-district, the current possibility place of terminal correspondence, if, obtain adjacent cell information, and to terminal current may the sub-district, place and neighbor cell carry out paging, otherwise directly the paging corresponding district gets final product.
In above-mentioned second preferred embodiment, MSC can preserve the information table of information and each sub-district neighbor cell under other BSC of this MSC control of each sub-district.Like this, MSC is obtaining cell ID from location update message or in the page-response message, and from information table, obtain the adjacent cell information of this sub-district according to the information of this sub-district, afterwards, this sub-district and adjacent cell information thereof can be kept in the data description information of terminal correspondence.
In actual applications, terminal current possibility sub-district, place and neighbor cell thereof may coexist under the BSC, MSC may only preserve or obtain the sign of sub-district, the current possibility place of terminal, and to guarantee that MSC just can call out terminal current possibility sub-district, place and neighbor cell thereof for the first time, then also needs a kind of suitable paging method.For this reason, the invention provides the 3rd preferred embodiment.
Fig. 3 is the flow chart of the 3rd preferred embodiment of the inventive method.As shown in Figure 3, comprising:
Step S301:MSC is the current information that may the sub-district, place of the terminal of paging as required, and current BSC that may sub-district, place correspondence carries out paging to terminal.
MSC can preserve or obtain terminal current may the place relevant information of sub-district, the relevant information here can be current sign CI, overall identification CGI, terminal current BSC information (for example numbering) and the current BTS information (for example numbering) that may sub-district, place correspondence of terminal that may sub-district, place correspondence that may the sub-district, place of terminal.MSC can obtain above-mentioned relevant information when terminal is initiated position updating request, can also obtain above-mentioned information when page response before.
MSC can determine the BSC of needs paging according to above-mentioned relevant information, and then initiates paging to BSC.Further, when MSC initiates paging to BSC, above-mentioned relevant information can be offered BSC.Certainly, if BSC has also preserved or the above-mentioned relevant information of acquisition of having the ability, then MSC can offer BSC with above-mentioned relevant information.
Step S302:BSC obtains the information of neighbor cell according to the relevant information of sub-district, the current possibility place of terminal, and then paging is carried out in terminal current possibility sub-district, place and neighbor cell.
Can preserve the information of each sub-district of control and the information of neighbor cell thereof among the BSC, also can obtain these information, for example, when BSC need inquire about the information of neighbor cell of a sub-district, can inquire about the information of the neighbor cell of having preserved, also can obtain the information of neighbor cell by other approach.The information of neighbor cell can be the BSC information (for example numbering) of cell ID CI, sub-district overall identification CGI, sub-district correspondence and the BTS information (for example numbering) of sub-district correspondence.In actual applications, terminal current possibility sub-district, place and neighbor cell thereof may not coexist under the BSC, in this case, BSC can only preserve or obtain the information of the neighbor cell of own control, and other can not preserve or not need acquisition in the information of the neighbor cell of own control range.The front was mentioned, present embodiment hypothesis terminal current may the sub-district, place and neighbor cell coexist under the BSC, so BSC can preserve or obtain the information of current all neighbor cells that may sub-district, place correspondence of terminal.
Step S303:MSC judges in the default time whether receive page response, if, carry out subsequent treatment, otherwise, step S304 changeed.
Step S304: enlarge paging range or finish paging.
Enlarge paging range a variety of modes are arranged, for example, can carry out paging to other sub-districts except that terminal current possibility sub-district, place and neighbor cell in the lane place, also can carry out paging to all sub-districts in the lane place, can also carry out paging to the sub-district adjacent with neighbor cell, in addition can also to terminal may be movable other sub-districts or current be not that very busy neighbor cell carries out paging.
Need to prove that step S303 has a variety of implementations, a variety of replacement schemes are also arranged.For example, BSC can judge in the default time whether receive page response, if, then MSC is returned page response, otherwise, also to notify MSC not receive page response.The result that MSC can return according to BSC determines whether to receive page response, if, carry out subsequent treatment, otherwise, step S304 changeed.Again for example, if BTS has participated in calling, then BTS also can judge in the default time whether receive page response, if, then BSC is returned page response, otherwise, also to notify BSC not receive page response.The result that BSC can return according to BTS determines whether to receive page response, and then whether decision reports the paging result to MSC again.Certainly, the paging result that MSC or BSC can also return according to BSC or BTS in conjunction with the default time, takes all factors into consideration and whether can receive page response again.
Above-mentioned the 3rd preferred embodiment has a variety of concrete implementations, and a variety of alternate embodiment are also arranged.For example, in above-mentioned the 3rd preferred embodiment, when a sub-district and neighbor cell thereof do not coexist BSC following time, MSC can only preserve the BSC information of the sign of this sub-district and the neighbor cell correspondence under this MSC, and does not need to preserve the sign of the neighbor cell under this MSC again.Promptly, when terminal is initiated the position renewal, BSC can only send the sign of this sub-district and the BSC information of the neighbor cell correspondence under this MSC to the MSC preservation, like this, MSC can be arranged on cell ID in the beep-page message when paging BSC, and BSC is after obtaining the beep-page message of MSC, obtain the information of neighbor cell according to the cell ID in the beep-page message, afterwards the neighbor cell of this sub-district is carried out paging and get final product.
In above-mentioned the 3rd preferred embodiment, MSC can judge that sub-district, the current possibility place of terminal is adjacent the sub-district and whether belongs to a BSC, and the time to the BSC issuing page message, also be arranged on the sign that whether belongs to a BSC in the beep-page message, like this, BSC obtain that terminal is current may the sign of sub-district, place after, needn't judge again that this sub-district is whether in the control range of oneself, and only need obtain the information of the neighbor cell of this sub-district, and carry out follow-up paging action and get final product.Concrete, BSC receives a beep-page message, carry in the beep-page message terminal current may the place sign and the sign in the control range of this BSC whether of sub-district, BSC obtains the information of neighbor cell according to the sign of sub-district, the current possibility place of terminal, and determine directly that according to sign sub-district, the current possible place of terminal is whether in the control range of oneself, if in the control range of oneself, then paging is carried out in terminal current possibility sub-district, place and neighbor cell thereof, otherwise, only neighbor cell is carried out paging.
In above-mentioned the 3rd preferred embodiment, if MSC sends to the current sign that may the sub-district, place of a carried terminal in the beep-page message of each BSC, then can also beep-page message indicate terminal current may the place sub-district whether in the control range of this BSC, like this, BSC determine terminal current may the sub-district, place be in the control range of this BSC, then paging is carried out in terminal current possibility sub-district, place and neighbor cell, otherwise, only neighbor cell is carried out paging.
Certainly, in order to reduce the amount of calculation of BSC, MSC is to the BSC paging time, can only the cell information in the BSC control range (no matter being terminal current possibility place cell information or its adjacent cell information) be offered BSC, like this, BSC can directly carry out paging to the sub-district of these appointments and get final product, certainly, MSC is to the BSC paging time, the information of sub-district, the current possibility place of terminal and the adjacent cell information in the BSC control range can also be offered BSC, like this, BSC just need be before paging, again according to the information of the current information acquisition neighbor cell that may the sub-district, place of terminal.
In above-mentioned all embodiment, call terminal is current if desired may the sub-district, place and neighbor cell, then can call terminal current may the sub-district, place the time, neighbor cell that can paging part, in other words, can not that all neighbor cells are all carried out paging, further, can select the most possible movable neighbor cell of terminal to carry out paging, can further save interface-free resources like this.
In above-mentioned all embodiment, MSC can only preserve the BSC information of sub-district, the current possibility place of terminal correspondence, and like this, MSC is when paging, and directly the BSC of sub-district, the current possibility place of call terminal correspondence gets final product.
In above-mentioned all embodiment, MSC can only preserve the BTS information of sub-district, the current possibility place of terminal correspondence, like this, MSC is when paging, directly call terminal current may the place BSC of sub-district correspondence, and the BTS information of correspondence offered BSC, after BSC receives beep-page message, directly BTS is carried out paging according to BTS information wherein and get final product.
In above-mentioned all embodiment, BSC is when MSC transmits page-response message, can be in page-response message the current information that may the sub-district, place of carried terminal, MSC is after receiving page-response message, whether the information that can judge sub-district, the current possibility place of terminal changes, if, the current information that may the sub-district, place of the terminal of then upgrade preserving.Certainly, MSC can not judge yet, but the current information that may the sub-district, place of the terminal that directly BSC is provided preserves, so that use during this terminal of next paging.
Above-mentioned all embodiment are that to initiate paging with MSC be example, and in actual applications, BSC and BTS also might initiate paging or be triggered by MSC or BSC to initiate paging.For this reason, the present invention also provides the 4th, the 5th, the 6th and the 7th preferred embodiment.
Fig. 4 is the flow chart of the 4th preferred embodiment of the inventive method.As shown in Figure 4, comprising:
The step S401:BSC couple of BTS relevant with the terminal that needs paging carries out paging.
BSC can preserve or obtain the relevant information of sub-district, the current possibility place of terminal, the relevant information here can be sign CI, the overall identification CGI of sub-district, the current possibility place of terminal and the BTS information (for example numbering) of sub-district, the current possibility place of terminal correspondence, even can also be the sign of neighbor cell.BSC can obtain above-mentioned relevant information when terminal is initiated position updating request, can also obtain above-mentioned information when page response before.
BSC can determine the BTS relevant with terminal according to above-mentioned relevant information, and then initiates paging to BTS.Further, when BSC initiates paging to BTS, above-mentioned relevant information can be offered BTS.Certainly, if BTS has also preserved or the above-mentioned relevant information of acquisition of having the ability, then BSC can offer BTS with above-mentioned relevant information.
Step S402:BTS carries out paging to the sub-district at the current possibility of terminal place.
BTS can carry out paging to all sub-districts of oneself controlling, also can only carry out paging to the sub-district at the current possibility of terminal place.
