Abstract
The present invention discloses a positioning paging method for short messages, which is used for solving the problem that a mobile terminal can not be receive short messages in the prior art if the mobile terminal moves to other cells in the short message positioning paging period. A mobile switching center sends a positioning paging request to a position region where the mobile terminal is placed after receiving a short message request; the mobile terminal returns a positioning paging response carrying a cell identification list of current activated cells of the mobile terminal to the mobile switching center through an affiliated base station controller after receiving the positioning paging request; the mobile switching center carries out short message paging to the mobile terminal according to the cell identification list. Thus, even if the mobile terminal moves to other cells after the positioning paging is responded, the mobile terminal can also receive short messages, and the number of the current activated cells of the mobile terminal is far smaller than the number of all cells in the position region so as to ensure that a wireless side device can not be impacted by the sending of short messages.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is carrying out in the short message paging portable terminal, still adopt the mode of positioning paging to reduce impact to wireless side, but what carry in the positioning paging response is the CELL ID tabulation of the current activation of portable terminal sub-district, even portable terminal moves to other sub-district again after the positioning paging response like this, also can receive short message, and the number of the number of the current activation of portable terminal sub-district all sub-districts in the lane place, thereby guaranteed that wireless side can not be subjected to the impact that short message sends.
As shown in Figure 3, when portable terminal A sent SMS message to portable terminal B, the process of portable terminal B being carried out the short message paging was as follows:
Step S10, SMC are to the MSC of the current visit of the portable terminal B request of sending SMS message;
When portable terminal A sends SMS message to portable terminal B, the short message that sends by the MSC of SMC mobile terminal receive A current service at first, SMC according to the number of portable terminal B (as the MSISDN in the gsm system, or the MDN in the cdma system) from HLR (the Home LocationRegister of portable terminal B, attaching position register) obtain the address of the MSC at the current place of portable terminal B, SMC sends the short message request to the MSC of the current visit of portable terminal.
Step S11, MSC send the positioning paging request to portable terminal B position district;
After MSC receives the short message request, from the current VLR of portable terminal B (Visitor LocationRegister, VLR Visitor Location Register) obtain the information in the current position of portable terminal B district in, MSC sends the positioning paging request to the BSC of the lane place correspondence at portable terminal B place.
Step S12, portable terminal are replied the positioning paging response to mobile switching centre, wherein carry the CELL ID tabulation of the current activation of portable terminal sub-district;
After portable terminal B receives this positioning paging request, reply page response to BSC, the CELL ID that has sub-district, the current place of portable terminal B in the page response, BSC upgrades according to the Active Set of this page response to portable terminal B, and the CELL ID of the current activation sub-district after will upgrading tabulation sends to MSC.
Step S13, mobile switching centre tabulate according to CELL ID portable terminal are carried out the short message paging;
In the present invention, according to CELL ID tabulation portable terminal being carried out the short message paging can adopt dual mode to carry out.
First kind of mode is the MSC paging request that sends SMS message of all sub-districts in CELL ID tabulation simultaneously;
The current activation of portable terminal sub-district is generally speaking in the coverage of same BSC, MSC is at first to the pairing BSC in the current activation sub-district paging request that sends SMS message, wherein have the CELL ID tabulation of the current activation of portable terminal B sub-district, after BSC receives short message paging request, the paging request that sends SMS message of all sub-districts in CELL ID tabulation simultaneously, after portable terminal B receives short message, can reply response message to BSC, BSC can reply the paging success message to MSC after receiving this response message; If BSC does not receive the response message of portable terminal B in limiting time, then reply paging failure message to MSC.
As shown in Figure 4, the second way is the paging request that sends SMS message of the each only sub-district in CELL ID tabulation of MSC, and concrete steps are as follows:
Step S130, MSC are to the pairing BSC in the current activation sub-district paging request that sends SMS message, wherein carry the CELL ID of first sub-district in the CELL ID tabulation, after BSC receives short message paging request, according to the CELL ID of first sub-district to its paging request that sends SMS message;
Step S131, if portable terminal B receives this short message, then reply response message to BSC, BSC replys the paging success message to MSC, flow process finishes; If BSC does not receive the response message of portable terminal B in limiting time, then reply paging failure message, execution in step S132 to MSC;
After step S132, MSC receive paging failure message, judge in the CELL ID tabulation whether have not paged sub-district, if do not exist, then flow process finishes, the short message paging failure; If exist, then execution in step S132;
Step S133, MSC are to the pairing BSC in the current activation sub-district paging request that sends SMS message, the CELL ID that wherein has a sub-district in the sub-district not paged in the CELL ID tabulation, after BSC receives short message paging request, according to this CELL ID paging request that sends SMS message;
Step S134, if portable terminal B receives short message, then reply response message to BSC, BSC replys the paging success message to MSC, flow process finishes; If BSC does not receive the response message of portable terminal B in limiting time, then reply paging failure message, execution in step S132 to MSC.
Generally speaking, the sub-district at the current place of portable terminal B is the stronger sub-district of pilot signal strength, if BSC sorts to the power of the CELL ID of MSC transmission tabulation according to the pilot signal of sub-district among the step S12, the sub-district that is the pilot signal strength maximum comes first that CELL ID tabulates, then in the second way of step S13, MSC can carry out the short message paging to the sub-district in the CELL ID tabulation according to the order of pilot signal power, thereby effectively reduce the send SMS message total degree of paging request of MSC, take less Radio Resource.
When a certain portable terminal is positioned at the overlapping area of sub-district A, B, C, system sends SMS message to it, at first MSC sends the positioning paging request to BSC, BSC is by the CELL ID tabulation of page response with the current activation of portable terminal sub-district, and promptly the cell identification list of sub-district A, B, C sends to MSC.This moment, terminal moved to the independent coverage of sub-district C, broke away from A, B sub-district fully.MSC has the CELL ID of sub-district A, B, C in short-message sending, BSC descends short-message sending to these three sub-districts, even portable terminal also can be received short message in A, B, three moving between cells of C like this.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
