Description

Paging method and device
Technical Field
The present invention relates to communications technologies, and in particular, to paging technologies.
Background
When the paging center pages the called party, the position of the called party needs to be known, otherwise, if the called party can be successfully paged once, the whole network paging is required. For example, in a Global System for Mobile communications (GSM), there are many cells under a Mobile Switching Center (MSC). When the MSC needs to page the terminal, it also needs to know the current location of the terminal, and if the terminal is not known, it needs to page the terminal, it only needs to page all cells under the MSC. However, the paging range involved in this paging method is too large, resulting in large air interface resources for paging.
At present, in order to avoid occupying a large amount of air interface resources during paging, all cells under one MSC may be divided into a plurality of location areas, each location area includes a plurality of cells, so that when a location of a terminal changes, for example, when a cell is updated, it is determined whether an updated new cell is in a new location area, if so, a location updating procedure is initiated, that is, new location information is notified to the MSC, otherwise, the location updating procedure is not initiated. In this case, if the MSC does not obtain the accurate location information of the terminal and needs to page the terminal, it only needs to page all cells included in the location area where the terminal is located. Compared with the mode of paging all cells under the MSC, the method saves air interface resources to a certain extent. However, since the number of cells included in each location area is still large, the MSC still occupies relatively many air interface resources when paging all the cells included in the location area without obtaining accurate location information of the terminal. If a paging takes up many air interface resources during a busy period, some paging may be delayed or failed.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a paging method and apparatus, so as to implement paging on a terminal on the premise of occupying as few air interface resources as possible.
The invention provides an embodiment of a paging method, which comprises the following steps: determining a paging range related to a terminal according to related information of a cell where the terminal needing paging is possibly located currently; paging the determined paging range; the determined paging range is a cell where the terminal is possibly located currently and at least one adjacent cell; and if the paging fails, expanding the paging range or finishing the paging.
The invention provides an embodiment of a paging device, comprising: a paging range determining unit, configured to determine a paging range associated with a terminal according to information related to a cell in which the terminal that needs paging may be currently located; the paging unit is used for paging the determined paging range, and if the paging fails, the paging range is expanded or the paging is ended; the determined paging range is a cell where the terminal is possibly located currently and at least one adjacent cell.
In all the above embodiments, the paging range related to the terminal is only paged first, and since the range of activities of the user using the terminal is basically limited every day, or the user using the terminal basically activities in one cell or an adjacent cell every day, in this case, if the paging range related to the terminal is paged first, the probability of success of one paging is relatively high, and then paging of other unrelated cells is avoided, so that air interface resources can be saved.

Detailed Description
First, the overall technical solution of an embodiment of the paging method provided by the present invention is explained. Such a method embodiment comprises: determining a paging range related to a terminal according to related information of a cell where the terminal needing paging is possibly located currently; paging the determined paging range; and if the paging fails, expanding the paging range or finishing the paging.
The paging range related to the terminal may be a cell where the terminal may be currently located, and information of the cell where the terminal may be currently located may be originally stored information, obtained original information, or information deduced from the originally stored information and/or the obtained original information; the paging range related to the terminal may also be a cell where the terminal may be currently located and at least one neighboring cell, and of course, the information of the cell where the terminal may be currently located and the information of the at least one neighboring cell may also be originally stored information, obtained original information, or information deduced from the originally stored information and/or the obtained original information.
If the paging for the paging range related to the terminal fails, the paging range may be optionally expanded, and the paging may be terminated.
In addition, the call may be initiated by an MSC, or may be a Base Station Controller (BSC) under the MSC, or may be a Base transceiver Station or a Base Station (BTS) under the BSC.
The above-described method embodiments are described in detail below with reference to several preferred embodiments.
Fig. 1 is a flow chart of a first preferred embodiment of the method of the present invention. As shown in fig. 1, includes:
step S101: the MSC pages the BSC associated with the terminal that needs to be paged.
The MSC stores the relevant information of the cell where the terminal may be currently located, where the relevant information may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BSC information (e.g., a number) corresponding to the cell where the terminal may be currently located, and BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located, and may also be an identifier CI of the cell where the terminal may be currently located and an identifier of an adjacent cell thereof. The MSC may obtain the relevant information when the terminal initiates a location update request, and may also obtain the information in a previous paging response.
The MSC can determine the BSC related to the terminal according to the related information, and then initiate paging to the BSC. Further, when the MSC initiates paging to the BSC, the relevant information may be provided to the BSC.
Of course, if the BSC also stores or has the ability to obtain the relevant information, the MSC may not provide the relevant information to the BSC.
Step S102: the BSC pages the cell in which the terminal may currently be located.
The BSC may obtain and store the relevant information of the cell where the terminal may be currently located when the terminal initiates a location update request to the MSC, or may receive the relevant information sent by the MSC. The BSC can page all the cells controlled by the BSC according to the information, or only page the BTS corresponding to the cell where the terminal is possibly located currently, after receiving the paging information, the BTS can page all the cells controlled by the BSC, or only page the cell where the terminal is possibly located currently.
Step S103: the MSC judges whether the paging response is received within the preset time, if so, the MSC carries out subsequent processing, and if not, the MSC transfers to the step S104.
Step S104: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells in the location area except for the cell where the terminal may be currently located, it may page all cells in the location area, it may page at least one neighboring cell of the cell where the terminal may be currently located, and it may even page other cells where the terminal may be active or neighboring cells that are not busy currently.
If the MSC needs to page at least one neighboring cell of the cell where the terminal may be currently located, the MSC may determine which one or more neighboring cells need to be paged, possibly a part of the neighboring cells, or possibly all the neighboring cells according to the relevant information of the cell where the terminal may be currently located, which is stored or obtained. For example, the MSC may page the BSC corresponding to the neighboring cell, and after receiving the paging message, the BSC may page all the cells controlled by the BSC, may also page the BTS corresponding to the neighboring cell, and the BTS may page all the cells controlled by the BTS, or may page only the neighboring cell. It should be noted that, a cell where the terminal may be currently located and an adjacent cell may be under one BSC or BTS, or may be under one BSC or BTS, if they are under one BSC or BTS, the MSC may page different BSCs corresponding to all adjacent cells that need to be paged, or may select a BSC corresponding to one or several adjacent cells that need to be paged, and similarly, the BSC may also page different BTSs corresponding to all adjacent cells that need to be paged, or may select one or several BTSs corresponding to the adjacent cells that need to be paged.
For the case where the MSC pages other cells that the terminal may be active, the MSC may determine other cells that the terminal may be active in based on the previous activity record for the terminal. There are many ways to implement this, one way of implementing this is that the MSC can store or obtain records of the terminal activity, for example, in which cell or cells the terminal is often active, and when necessary, the MSC can determine other cells that the terminal may be active in according to these records, and then decide which cells to page again.
It should be noted that there are many implementations and many alternatives for step S103. For example, the BSC may determine whether a paging response is received within a preset time, and if so, return the paging response to the MSC, otherwise, notify the MSC that the paging response is not received. The MSC may determine whether the paging response can be received according to the result returned by the BSC, if so, perform the subsequent processing, otherwise, go to step S104. For another example, if the BTS is engaged in a call, the BTS may also determine whether a paging response is received within a preset time, and if so, return a paging response to the BSC, otherwise, notify the BSC that no paging response is received. The BSC can determine whether the paging response can be received according to the result returned by the BTS, and further determine whether to report the paging result to the MSC. Of course, the MSC or BSC may also comprehensively consider whether a paging response can be received according to the paging result returned by the BSC or BTS, in combination with the preset time.
In the first preferred embodiment described above, the MSC first pages the cell in which the terminal is currently likely to be located. Since the user using the terminal is in a relatively fixed cell in most of the time, and the location update message sent by the terminal periodically can inform the MSC of the cell where the terminal is currently located in time, generally, the cell where the paging terminal is currently likely to be located basically successfully pages the terminal, so that the problem that the MSC starts paging for the location area in a large range to occupy a large amount of air interface resources is solved.
In practice, the terminal may be located at the boundary between two cells for a long time, and may frequently switch back and forth between the two cells at the boundary, and if the first paging is successful, the paging may be performed on the cell where the terminal may be currently located and the neighboring cells during the first paging. To this end, the invention provides a second preferred embodiment.
Fig. 2 is a flow chart of a second preferred embodiment of the method of the present invention. As shown in fig. 2, includes:
step S201: the MSC pages the related BSC according to the information of the cell where the terminal needing paging is possibly located currently and the information of the adjacent cell.
The MSC may store or obtain related information of a cell where the terminal may be currently located, where the related information may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BSC information (e.g., a number) corresponding to the cell where the terminal may be currently located, BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located, or an identifier of an adjacent cell. Specifically, the MSC may also store or obtain an information table of each cell and its neighboring cells. The MSC may obtain the relevant information when the terminal initiates a location update request, and may also obtain the information in a previous paging response.
The MSC can determine the related BSC according to the related information, and then initiate paging to the BSC. Further, when the MSC initiates paging to the BSC, the relevant information may be provided to the BSC. Of course, if the BSC also stores or has the ability to obtain the relevant information, the MSC may not provide the relevant information to the BSC.
In addition, a cell where the terminal may be currently located may correspond to the same BSC as an adjacent cell, or may correspond to different BSCs, and further, these adjacent cells may correspond to the same BSC or may correspond to different BSCs, so that the MSC determines that there may be one or more BSCs to be paged, and thus there may be one or more BSCs to be paged by the MSC.
Step S202: the BSC pages the cell and/or neighboring cells in which the terminal may currently be located.
In step S201, the BSC may store or obtain the relevant information of the cell where the terminal may be currently located, or may receive the relevant information provided by the MSC. The BSC may page all cells controlled by the BSC according to the information, or may page only the BTS corresponding to the cell where the terminal may be currently located and/or the neighboring cell. It should be noted that, if the cell where the terminal may be currently located and the neighboring cell are different from each other under one BSC, there may be multiple BSCs for MSC paging, and after receiving the paging message, these BSCs need to page the cell where the terminal controlled by themselves may be currently located and/or the neighboring cell. If BSC pages the BTS corresponding to the cell where the terminal may be located and/or the adjacent cell, the BTS may page all the cells controlled by the BTS after receiving the paging message, or may page only the cell where the terminal may be located and/or the adjacent cell.
Step S203: the MSC determines whether a paging response is received within a preset time, and if so, performs subsequent processing, otherwise, goes to step S204.
Step S204: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells in the location area except the cell where the terminal may be currently located and the neighboring cell, it may page all cells in the location area, it may page the cell adjacent to the neighboring cell, and it may even page other cells where the terminal may be active or the neighboring cell that is not busy currently.
It should be noted that there are many implementations and many alternatives for step S203. For example, the BSC may determine whether a paging response is received within a preset time, and if so, return the paging response to the MSC, otherwise, notify the MSC that the paging response is not received. The MSC may determine whether the paging response can be received according to the result returned by the BSC, and if so, perform subsequent processing, otherwise, go to step S204. For another example, if the BTS is engaged in a call, the BTS may also determine whether a paging response is received within a preset time, and if so, return a paging response to the BSC, otherwise, notify the BSC that no paging response is received. The BSC can determine whether the paging response can be received according to the result returned by the BTS, and further determine whether to report the paging result to the MSC. Of course, the MSC or BSC may also comprehensively consider whether a paging response can be received according to the paging result returned by the BSC or BTS, in combination with the preset time.
In the second preferred embodiment, the MSC first pages the cell where the terminal is currently likely to be and the neighboring cells. The second preferred embodiment also largely ensures that the first paging will be successful, since a user will not leave a cell and the area formed by neighbouring cells most of the time.
In the second preferred embodiment, when the cell where the terminal may be currently located and its neighboring cell are both under one BSC, the MSC may only need to store the identifier of the cell where the terminal may be currently located, and does not need to store the identifier of its neighboring cell. That is, when the terminal initiates location update, the BSC does not need to transmit the neighboring cell information of the cell where the terminal may be currently located to the MSC, but only transmits the identification information of the cell where the terminal may be currently located to the MSC for storage, so that when the MSC initiates paging, the BSC can obtain the information of the neighboring cell according to the cell identification information in the paging message after obtaining the paging message of the MSC, and then pages the cell where the terminal may be currently located and the neighboring cell thereof. Obviously, this processing method can save signaling resources.
In the second preferred embodiment, when the MSC initiates paging to the BSC corresponding to the cell where the terminal may be currently located, the MSC may only provide the identification information of the cell where the terminal may be currently located to the corresponding BSC, and when sending a paging message to the BSC corresponding to the neighboring cell of the cell where the terminal may be currently located, the MSC may only provide the identification information of the neighboring cell to the corresponding BSC, so that the BSC corresponding to the cell where the terminal may be currently located may obtain the identification information of the neighboring cell according to the obtained identification information of the cell where the terminal may be currently located, and then page the cell where the terminal may be currently located and the neighboring cell thereof, and when the BSC not corresponding to the cell where the terminal may be currently located obtains the cell information, the BSC may directly page the cell. In addition, the paging message sent by the MSC to the BSC may further include a flag indicating whether the BSC corresponds to a cell where the terminal may be currently located, so as to assist the BSC in determining. For example, the BSC may determine whether it is the BSC corresponding to the cell where the terminal may be currently located according to the flag, and if so, obtain the information of the neighboring cell, and page the cell where the terminal may be currently located and the neighboring cell, otherwise, directly page the corresponding cell.
In the second preferred embodiment, the MSC may store information of each cell and an information table of neighboring cells of each cell under other BSCs controlled by the MSC. In this way, the MSC acquires the cell identifier from the location update message or the paging response message, and acquires the neighboring cell information of the cell from the information table according to the information of the cell, and then, the MSC can store the cell and the neighboring cell information in the data description information corresponding to the terminal.
In practical application, a cell where a terminal may be currently located and an adjacent cell thereof may be under one BSC, and an MSC may only store or obtain an identifier of the cell where the terminal may be currently located, and an appropriate paging method is also needed to ensure that the MSC can call the cell where the terminal may be currently located and the adjacent cell thereof for the first time. To this end, the present invention provides a third preferred embodiment.
Fig. 3 is a flow chart of a third preferred embodiment of the method of the present invention. As shown in fig. 3, includes:
step S301: and the MSC pages the BSC corresponding to the cell where the terminal is possibly located according to the information of the cell where the terminal is possibly located.
The MSC may store or obtain related information of a cell where the terminal may be currently located, where the related information may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BSC information (e.g., a number) corresponding to the cell where the terminal may be currently located, and BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located. The MSC may obtain the relevant information when the terminal initiates a location update request, and may also obtain the information in a previous paging response.
The MSC can determine the BSC needing paging according to the related information and further initiate paging to the BSC. Further, when the MSC initiates paging to the BSC, the relevant information may be provided to the BSC. Of course, if the BSC also stores or has the ability to obtain the relevant information, the MSC may not provide the relevant information to the BSC.
Step S302: and the BSC acquires the information of the adjacent cells according to the relevant information of the cells where the terminal is possibly located, and further pages the cells where the terminal is possibly located and the adjacent cells.
The BSC may store information of each cell under control and information of neighboring cells thereof, or may obtain the information, for example, when the BSC needs to query information of neighboring cells of a cell, the BSC may query information of neighboring cells already stored, or may obtain information of neighboring cells through other approaches. The information of the neighboring cell may be cell identity CI, cell global identity CGI, BSC information (e.g., number) corresponding to the cell, and BTS information (e.g., number) corresponding to the cell. In practical application, a cell where a terminal may be currently located and a neighboring cell thereof may be different from each other under one BSC, and in this case, the BSC may only store or obtain information of neighboring cells controlled by the BSC, and information of other neighboring cells not in the control range of the BSC may not be stored or need not be obtained. As mentioned above, in this embodiment, it is assumed that the cell where the terminal may be currently located and the neighboring cells thereof are under the same BSC, so that the BSC may store or obtain information of all neighboring cells corresponding to the cell where the terminal may be currently located.
Step S303: the MSC determines whether a paging response is received within a preset time, and if so, performs subsequent processing, otherwise, goes to step S304.
Step S304: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells in the location area except the cell where the terminal may be currently located and the neighboring cell, it may page all cells in the location area, it may page the cell adjacent to the neighboring cell, and it may even page other cells where the terminal may be active or the neighboring cell that is not busy currently.
It should be noted that there are many implementations and many alternatives for step S303. For example, the BSC may determine whether a paging response is received within a preset time, and if so, return the paging response to the MSC, otherwise, notify the MSC that the paging response is not received. The MSC may determine whether the paging response can be received according to the result returned by the BSC, if so, perform subsequent processing, otherwise, go to step S304. For another example, if the BTS is engaged in a call, the BTS may also determine whether a paging response is received within a preset time, and if so, return a paging response to the BSC, otherwise, notify the BSC that no paging response is received. The BSC can determine whether the paging response can be received according to the result returned by the BTS, and further determine whether to report the paging result to the MSC. Of course, the MSC or BSC may also comprehensively consider whether a paging response can be received according to the paging result returned by the BSC or BTS, in combination with the preset time.
The third preferred embodiment described above has many specific implementations and many alternative implementations. For example, in the third preferred embodiment, when a cell and its neighboring cells are different under a BSC, the MSC may only store the identifier of the cell and the BSC information corresponding to the neighboring cells under the MSC, and does not need to store the identifiers of the neighboring cells under the MSC. That is, when the terminal initiates location update, the BSC may only transmit the identity of the cell and the BSC information corresponding to the neighboring cell under the MSC to the MSC for storage, so that the MSC may set the cell identity in the paging message when paging the BSC, after the BSC obtains the paging message of the MSC, the BSC obtains the information of the neighboring cell according to the cell identity in the paging message, and then pages the neighboring cell of the cell.
In the third preferred embodiment, the MSC may determine whether the cell where the terminal may be currently located and the neighboring cell belong to a BSC, and set a flag indicating whether the cell belongs to a BSC in the paging message when the paging message is sent to the BSC, so that after the BSC obtains the identifier of the cell where the terminal may be currently located, the BSC does not need to determine whether the cell is within its own control range, but only needs to obtain information of the neighboring cell of the cell, and performs a subsequent paging operation. Specifically, the BSC receives a paging message, where the paging message carries an identifier of a cell where the terminal may be currently located and a flag indicating whether the cell is within a control range of the BSC, and the BSC obtains information of an adjacent cell according to the identifier of the cell where the terminal may be currently located, and directly determines whether the cell where the terminal may be currently located is within its own control range according to the flag, if the cell is within its own control range, pages the cell where the terminal may be currently located and its adjacent cell, otherwise, pages only the adjacent cell.
In the third preferred embodiment, if the paging message sent by the MSC to each BSC only carries the identifier of the cell where the terminal may be currently located, the paging message may also indicate whether the cell where the terminal may be currently located is within the control range of the BSC, so that the BSC performs paging on the cell where the terminal may be currently located and the neighboring cell if it is determined that the cell where the terminal may be currently located is within the control range of the BSC, otherwise, only performs paging on the neighboring cell.
Certainly, in order to reduce the calculation workload of the BSC, when the MSC pages the BSC, the MSC may only provide the cell information (whether the cell information where the terminal may be currently located or the adjacent cell information thereof) within the control range of the BSC to the BSC, so that the BSC may directly page the specified cells, and certainly, when the MSC pages the BSC, the MSC may also provide the information of the cell where the terminal may be currently located and the adjacent cell information within the control range of the BSC to the BSC, so that the BSC does not need to obtain the information of the adjacent cell according to the information of the cell where the terminal may be currently located before paging.
In all the above embodiments, if it is required to page the cell where the terminal may be currently located and the neighboring cells thereof, only part of the neighboring cells may be paged while the cell where the terminal may be currently located is paged, or all the neighboring cells may not be paged, and further, the neighboring cell where the terminal is most likely to be active may be selected to be paged, so that air interface resources may be further saved.
In all the above embodiments, the MSC may only store BSC information corresponding to a cell where the terminal may be currently located, so that the MSC may directly page the BSC corresponding to the cell where the terminal may be currently located when paging.
In all the embodiments, the MSC may only store the BTS information corresponding to the cell where the terminal may be currently located, so that the MSC may directly page the BSC corresponding to the cell where the terminal may be currently located when paging, and provide the corresponding BTS information to the BSC, and after receiving the paging message, the BSC may directly page the BTS according to the BTS information therein.
In all the above embodiments, when the BSC transmits the paging response message to the MSC, the BSC may carry information of a cell where the terminal may be currently located in the paging response message, and after receiving the paging response message, the MSC may determine whether the information of the cell where the terminal may be currently located changes, and if so, update the stored information of the cell where the terminal may be currently located. Of course, the MSC may not make the determination, but directly store the information of the cell where the terminal may be currently located, which is provided by the BSC, so as to be used when paging the terminal next time.
All the above embodiments take the example of MSC initiated paging, and in practical applications, BSC and BTS may also initiate paging or be triggered by MSC or BSC to initiate paging. To this end, the present invention also provides fourth, fifth, sixth and seventh preferred embodiments.
Fig. 4 is a flow chart of a fourth preferred embodiment of the method of the present invention. As shown in fig. 4, includes:
step S401: the BSC pages the BTSs associated with the terminals that need to be paged.
The BSC may store or obtain related information of a cell where the terminal may be currently located, where the related information may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located, and may even be an identifier of an adjacent cell. The BSC may obtain the related information when the terminal initiates a location update request, and may also obtain the information in a previous paging response.
The BSC may determine the BTS associated with the terminal based on the above-mentioned related information, and then initiate paging to the BTS. Further, when the BSC initiates paging to the BTS, the relevant information may be provided to the BTS. Of course, the BSC may not provide the relevant information to the BTS if the BTS also maintains or has the ability to obtain the relevant information.
Step S402: the BTS pages the cell in which the terminal may currently be located.
The BTS can page all cells controlled by the BTS, or only the cells where the terminal may be currently located.
Step S403: the BSC determines whether a paging response is received within a preset time, if so, performs subsequent processing, otherwise, goes to step S404.
Step S404: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells except the cell where the terminal may be currently located, or it may page all cells controlled by itself, if at least one neighboring cell of the cell where the terminal may be currently located is also in its control range, it may also page at least one neighboring cell of the cell where the terminal may be currently located, or even page other cells where the terminal may be active or neighboring cells that are not busy currently.
Fig. 5 is a flow chart of a fifth preferred embodiment of the method of the present invention. As shown in fig. 5, includes:
step S501: if the cell where the terminal is probably located and the at least one adjacent cell are in the control range of the BSC, the BSC pages the cell where the terminal is probably located and the at least one adjacent cell.
The cell in which the terminal may be currently located and at least one neighboring cell may be under the same BTS or may be different from one BTS, and if paging is to be performed on the cell in which the terminal may be currently located and at least one neighboring cell, the processing is performed conditionally. For example, if the cell where the terminal may be currently located and at least one neighboring cell are both under the same BTS, the BSC needs only to page the BTS; if the cell where the terminal may be currently located and at least one neighboring cell are not under one BTS, the BSC may page all BTSs corresponding to these cells.
Step S502: the BTS pages the cell in which the terminal may currently be located and/or at least one neighboring cell.
If the cell where the terminal may be currently located is under one BTS alone, the corresponding BTS may directly page the cell where the terminal may be currently located, or may page all cells within the control range, and another BTS or BTSs corresponding to the neighboring cell of the cell where the terminal may be currently located may directly page the neighboring cell controlled by itself, or may page all cells within the control range.
If the cell where the terminal may be located and the adjacent cells are under one BTS, the BTS can directly page the cells and can also page all the cells controlled by the BTS.
Step S503: the BSC determines whether a paging response is received within a preset time, if so, performs subsequent processing, otherwise, goes to step S504.
Step S504: expand the paging range or end the paging.
Fig. 6 is a flow chart of a sixth preferred embodiment of the method of the present invention. As shown in fig. 6, includes:
step S601: the BTS pages the cell in which the terminal that needs paging is currently likely to be located.
Step S602: the BTS judges whether a paging response is received within a preset time, and if so, performs subsequent processing, otherwise, goes to step S603.
Step S603: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells except the cell where the terminal may be currently located, it may page all cells controlled by itself, and it may page other cells where the terminal may be active or neighboring cells that are not busy currently.
Fig. 7 is a flow chart of a seventh preferred embodiment of the method of the present invention. As shown in fig. 7, includes:
step S701: the BTS pages the cell and part of the adjacent cells where the terminal needing paging is probably located currently. The selection of which neighbour cell or cells to page may be determined in practice, for example by selecting neighbour cells where the terminal may be active, or by selecting neighbour cells that are not currently busy.
Step S702: the BTS judges whether a paging response is received within a preset time, if so, carries out subsequent processing, and otherwise, goes to the step S703.
Step S703: expand the paging range or end the paging.
There are many ways to expand the paging range, for example, it may page other cells except the cell where the terminal may be currently located and the neighboring cell that has been paged, it may page all cells controlled by itself, and it may page other cells where the terminal may be active or other cells that are not busy currently.
Since all of the above method embodiments may be implemented by one or more apparatuses, the present invention further provides a paging apparatus embodiment, which includes: a paging range determining unit, configured to determine, according to information related to a cell where a terminal that needs to be paged may be located currently, a paging range that is related to the terminal and smaller than a location area; and the paging unit is used for paging the determined paging range, and expanding the paging range or finishing paging if the paging fails.
The relevant information of the cell where the terminal may be currently located may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BSC information (e.g., a number) corresponding to the cell where the terminal may be currently located, and BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located, or may be an identifier CI of the cell where the terminal may be currently located and an identifier of an adjacent cell thereof.
In the above embodiment of the paging device, the paging range determined by the paging range determining unit may be a cell where the terminal may be currently located, so that the paging unit may directly page the cell, and if the paging fails, the paging unit may page other cells in the location area except for the cell where the terminal may be currently located, may page all cells in the location area, may page at least one neighboring cell of the cell where the terminal may be currently located, and may even page other cells where the terminal may be active or neighboring cells that are not busy currently.
Of course, if the paging fails, the paging range determining unit may determine the paging range again after receiving the paging failure or a corresponding instruction, and then provide the determined paging range to the paging unit, and the paging unit pages the determined paging range. If the paging range is determined again by the paging range determining unit and the paging range determining unit determines at least one neighboring cell of the cell where the terminal may be currently located as the paging range again, it may be further determined which one or more neighboring cells are used as the paging range; if the paging range determination unit determines other cells that the terminal may be active as the range to page again, it may determine which cells are the cells that the terminal may be active in according to the previous activity record of the terminal.
In the above embodiment of the paging device, the paging range determined by the paging range determining unit may be a cell where the terminal may be currently located and at least one neighboring cell, so that the paging unit may directly page the cell where the terminal may be currently located and the at least one neighboring cell, and if the paging fails, the paging unit may page cells other than the cell where the terminal may be currently located in the location area, may page all cells in the location area, may page cells neighboring the neighboring cell, and may even page other cells where the terminal may be active or neighboring cells that are not busy currently.
In the above embodiment of the paging device, the paging unit may determine whether paging is successful according to whether a paging response is received within a preset time, and if the paging response is received within the preset time, determine that paging is successful, otherwise, determine that paging is failed.
In the embodiment of the paging device, the method may further include: and the storage unit is used for storing the relevant information of the cell where the terminal is probably located currently. The relevant information of the cell where the terminal may be currently located may be an identifier CI of the cell where the terminal may be currently located, a global identifier CGI, BSC information (e.g., a number) corresponding to the cell where the terminal may be currently located, and BTS information (e.g., a number) corresponding to the cell where the terminal may be currently located, or may be an identifier CI of the cell where the terminal may be currently located and an identifier of an adjacent cell thereof. It should be noted that the paging device can be applied to the MSC, BSC, and BTS.
In all embodiments of the present invention, the paging range with few cells is paged first, and the success rate of the first paging is relatively high, even if the first paging fails, the paging range can be expanded, and the expanded paging range can even be limited, so that the success rate of paging is improved, and excessive air interface resources are not occupied.
In all embodiments of the present invention, when paging for the first time or paging for the second time, a cell in which the terminal may be active may be selected for paging, which may also save air interface resources and improve the probability of successful paging.
In all embodiments of the invention, when paging again, other cells which are not busy at present can be selected for paging, so that the burden of a network, particularly a busy cell, can be relieved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
