Abstract
The method comprises: a) setting the relevant information about neighboring cell in serving MSC; when MS roams into the neighboring cells, the serving MSC/visit location register (VLR) carries around the location area identification of the MS and the identification of boarder MSC to the home location register (HLR) to make location register; the HLR saves the location area identification of the MS and the identification of boarder MSC; b) when said MS is used as called side, the HLR respectively sends routing request to serving MSC and boarder MSC; c) when the serving MSC and boarder MSC receive said routing request, they respectively pages said MS.
Description
Technical field
The present invention relates to wireless communication system, relate in particular to a kind of in wireless communication system mobile switching centre (Mobile Switching Center, MSC) inter-system paging travelling carriage (Mobile Station, method MS).
Background technology
See also Fig. 1, when MS roams in the service overlapping region of two MSC, if BSS is (BaseStation System, base station sub-system) be configured to the time-delay registration, MS then might occur and from the primary importance district, switch to second place district, but MS does not initiate location registers as yet in second place district, this moment if MS as called, then call out and will be routed to a MSC, a MSC is when primary importance district paging MS, and MS does not have response.In order to improve the call completing rate of calling, the common practice is that a MSC sends out message to the 2nd MSC now, and at second place district paging MS, MS will have page response in second place district by the 2nd MSC.Can improve paging success rate like this, and then improve call completing rate.
By 41 agreements, the method for the MSC inter-system paging MS that present industry is commonly used has following two kinds:
The one, the ISPAGE mode, see also Fig. 2, the principal character of this mode is: when service MSC (SERVINGMSC) receives ROUTREQ message, carry out paging earlier,, then send ISPAGE message to border MSC (Border MSC) if calling called subscriber does not have response, by border MSC called paging down, paging receiving are responded, and distribution T LDN, in ispage message, bring service MSC, send originating MS C to by routreq message, locreq message again.Originating MS C is called to border MSC again.The timer default value of LOCREQ is 16 seconds in 41 agreements, and the default value of ROUTREQ timer is 10 seconds.
Yet a distinct disadvantage of ISPAGE mode is: under the situation of the default timer value of agreement, because the default value of ROUTREQ timer is less, have only 10 seconds, MSC is under the situation of no-response paging in service, send ISPAGE message to border MSC again, at this moment very possible ROUTREQ timer is the overtime call failure that causes earlier, and perhaps system does not have adequate time to wait for ispage message.As called subscriber the time, at this moment call out and discharge, so the practicality of this mode is less at border MSC page response.
The 2nd, the ISPAGE2 mode sees also Fig. 3, and the principal character of this mode is: call out after the Incoming, service MSC calling called subscriber does not have response, then send ISPAGE2 to border MSC, to called paging down, paging receiving response, be called to border MSC by service MSC again by border MSC.
Yet significant disadvantages of ISPAGE2 mode is: called paging does not have response just to border MSC transmission ISPAGE2 after calling out Incoming, therefore the call proceeding time is long, user satisfaction is low, and take the station to station call related resource between originating MS C, service MSC and the border MSC, cause the waste on the resource.
Summary of the invention
Technical problem to be solved by this invention is to provide the practicality of a kind of MSC of raising inter-system paging MS, and guarantees the speed that continues faster, and takies the method for mobile switching centre's inter-system paging travelling carriage of interexchange circuit resource with exceeding.

HLR checks whether affiliated Location Area Identification of this MS and the sign of border MSC are arranged in the user data information that is kept at this MS among this HLR, if have, then send route request information to service MSC and border MSC respectively, be used for after serving MSC and border MSC to receive described route request information the described MS of paging in its coverage respectively.
Described MS roams into the adjacent position district and comprises that MS is from roaming into adjacent position district and MS at the interval roaming in different adjacent positions both of these case with other the non-conterminous lane place, lane place of MSC.
Described HLR checks that the step of the sign whether affiliated Location Area Identification of this MS and border MSC are arranged in the user data information that is kept at this MS among this HLR is to carry out after HLR receives the location request message LOCREQ of originating MS C transmission.
Described further comprising the steps of after the step of the described MS of paging in its coverage respectively after serving MSC and border MSC to receive described route request information:
When service MSC or border MSC receive page-response message, HLR notice originating MS C, be used for originating MS C with call proceeding to corresponding M SC.
If border MSC receives page-response message, then described originating MS C is further comprising the steps of to the corresponding M SC with call proceeding: border MSC/VLR carries out location registers to HLR.
Described border MSC/VLR carries out location registers to HLR and further may further comprise the steps:
HLR receives the enroll in notifications message that border MSC/VLR sends, and has affiliated Location Area Identification of this MS and the sign of border MSC in this message;
After HLR receives this message, preserve affiliated Location Area Identification of this MS and the sign of border MSC, and send registration cancellation REGCANC message to service MSC/VLR.
The invention has the beneficial effects as follows: because the method for mobile switching centre of the present invention inter-system paging travelling carriage is to adopt HLR to send route request information to service MSC and border MSC respectively, after service MSC and border MSC receive route request information, the described MS of paging in its coverage respectively, therefore can improve the practicality of MSC inter-system paging MS, and guarantee the speed that continues faster, and take the interexchange circuit resource with exceeding.
