Abstract
The invention discloses a redirecting method of a called service. The Redirecting method of the called service includes that: a femto access point (FAP) base station receives paging request sent to a mobile station (MS) by a mobile switching center (MSC) through a femto gateway (FGW), and when the FAP receives the paging response of the MS and judges that the MS accords with redirecting conditions, and the FAP redirects the MS to an adjacent macro base station and does not feed back paging response to the MSC through the FGW; and after the MSC determines paging overtime or MS position updating, the MSC sends the paging request to the MS to the macro base station, and the macro base station sends the paging response fed back by the MS to the MSC. By adopting the redirecting method and the femto access point base station, paging success rate and calling building success rate can be improved.
Description
Technical field
The present invention relates to the redirecting technique of communication system, particularly a kind of reorientation method of called service and Home eNodeB.
Background technology
CDMA Femto scheme is a family or a medium-sized and small enterprises indoor application scheme end to end, and it mainly is made up of Femto gateway (FGW) and Home eNodeB (FAP).Home eNodeB FAP adopts curing net, especially the ADSL network of family or medium-sized and small enterprises to link to each other with Femto gateway (FGW) as passback, thereby the access mobile core net obtains abundant mobile service.And user mobile phone just and be located at the inner Femto base station communication of dwelling house or office, thereby signal quality is good, and bandwidth is big, and obtainable business is also abundanter, especially many new business of big, the delay sensitive of those bandwidth demands.
FAP is as a kind of small-sized access device of user side, and the access customer number of its permission is limited.When reaching maximum number of user, FAP can refuse current calling according to calling out the access strategy, and the user is redirected to adjacent macrocell.Femto supports user's access control in addition.Under non-open mode, FAP possibly refuse the service request of unauthorized user, and the user is redirected to adjacent macrocell.
The present redirected flow process of 1X voice calling service comparative maturity under the CDMA Femto, but being redirected of 1X speech called service is also not too perfect.
Fig. 1 is the reorientation method realization flow of present a kind of called service, and as shown in Figure 1, this flow process comprises:
MSC receives page-response message, thinks that MS inserts FAP, then sends assignment request through FAP to MS at subsequent step.
After step 103, therefore FAP possibly be redirected to MS in the adjacent macrocell through step a because factors such as access customer number purpose restriction can't allow MS to insert, and like this, MS does not just insert FAP.Based on above-mentioned processing, FAP owing to can't carry out assignment to MS, therefore can only pass through step 109～110 to MSC feedback Assignment Failure message after the assignment request that receives the MSC transmission.
In above-mentioned called reorientation method; FAP sends to MSC with paging response message through FGW, after MSC receives paging response message, even the terminal is redirected in the macrocell; MSC is this terminal of paging once more not also, thereby can cause paging failure (called can't the connection).
After MSC receives the paging response message of FAP transmission; Can send assignment request message to FAP through FGW; And FAP has been redirected to macrocell with terminal called this moment, and FAP replys assignment failure message to MSC, causes the call setup failure.It is thus clear that above-mentioned called reorientation method can cause the failure of paging and call setup.
Summary of the invention
The invention provides a kind of reorientation method and Home eNodeB of called service, can reduce the mortality that called service is redirected, improve paging success rate and call setup success rate.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of reorientation method of called service comprises:
Home eNodeB (FAP) receives the paging request to travelling carriage (MS) that MSC sends through femto gateway (FGW); When receiving the page response of said MS and adjudicate said MS, said FAP meets when being redirected condition; Said FAP is redirected to adjacent macro base station with said MS, and said FAP does not feed back page response through FGW to MSC;
After MSC confirmed that the overtime or definite MS of paging position is upgraded, said MSC sent the paging request to said MS to said macro base station, and said macro base station sends the page response of said MS feedback to said MSC.
Preferably, said judgement with the mode that MS meets the condition of being redirected is: whether according to current activation number of calls or said MS is authorized user, judges whether said MS meets redirected condition.
Preferably, when said FAP is operated in non-open mode,, then adjudicates said MS and meet redirected condition if said MS is a unauthorized user.
Preferably, maximum if current excited user number reaches when said FAP is operated in open mode and non-open mode, then adjudicate said MS and meet redirected condition.
Preferably, said FAP is redirected to adjacent macro base station with said MS and is: said FAP directly sends professional (service redirection) message that is redirected to the terminal.
Preferably; Said MSC confirms that the mode that the MS position is upgraded is: after said FAP is redirected to said macro base station with said MS; Said MS sends registration message to said macro base station; Said macro base station sends position updating request to said MSC, and said MSC confirms the renewal of said MS position after receiving said position updating request.
A kind of Home eNodeB (FAP) comprising: be redirected unit and interface unit;
Said interface unit is used to receive the page response to the paging request and the said MS feedback of travelling carriage (MS) that MSC sends through femto gateway (FGW), and after receiving the page response of said MS, notifies said redirected unit; Also be used for notice, carry out or do not carry out the operation to MSC feedback page response through FGW according to said redirected unit;
Said redirected unit, whether the said MS of judgement meets redirected condition after receiving the notice of said interface unit, if meet, then said MS is redirected to adjacent macro base station, and notifies said interface unit no longer to feed back page response through FGW to MSC; Otherwise, notify said interface unit to feed back page response to MSC through FGW.
Preferably, said redirected unit comprises redirected judgement subelement and redirect operation subelement;
Said redirected judgement subelement; Be used for after receiving the notice of said interface unit; Whether according to current activation number of calls or said MS is authorized user, judges whether said MS meets redirected condition, and court verdict is sent to said redirect operation subelement;
Said redirect operation subelement is used for when said MS meets the condition of being redirected, said MS being redirected to adjacent macro base station, and notifying said interface unit no longer to feed back page response through FGW to MSC; Also be used for when said MS does not meet the condition of being redirected, notifying said interface unit to feed back page response to MSC through FGW.
Preferably, when said FAP was operated in non-open mode, said redirected judgement subelement when judging whether said MS meets the condition of being redirected, if said MS is a unauthorized user, was then adjudicated said MS and is met redirected condition.

Embodiment
For making the object of the invention, technological means and advantage clearer, the present invention is explained further details below in conjunction with accompanying drawing.
In the called service reorientation method that background technology is mentioned, whether the process to the page response of MSC feedback MS is redirected MS with FAP, is two separate processes; In this case, FAP does not consider whether MS is redirected, as long as MS feedback page response, FAP will feed back page response to MSC, thereby makes MSC think that MS has inserted FAP, therefore directly sends assignment message through FAP to MS, is used for setting up calling out connecting; Yet for the MS that has been redirected, can't carry out assignment to MS, therefore can cause paging to be connected the failure of setting up with calling out through FAP.
In the present invention, on the one hand, for the MS that meets the condition that is redirected, when its behind FAP feedback page response, FAP is no longer to MSC feedback page response, fails with call setup thereby avoid MSC to send the paging failure that assignment causes through FAP to MS once more; Simultaneously, MSC sets up calling through macro base station paging MS and connects after the overtime or definite MS of paging position is upgraded, thereby improves the success rate of call setup.And, 1X voice system under the CDMA Femto that the method for the invention described above is not only applicable to mention in the background technology, suitable equally for other communication systems that comprise Home eNodeB, to carry out being redirected of called service.
Fig. 2 is the sketch map of the reorientation method flow process of called service in the embodiment of the invention.In the figure, be the concrete reorientation method of example explanation with 1X voice system under the CDMA Femto.As shown in Figure 2, this method comprises:
Step 204, MS identifies a paging request and comprises its identification code, then on access channel to page-response message of FAP loopback.
The processing of above-mentioned steps 201～204 is identical with existing processing mode, just repeats no more here.
Concrete FAP judges that whether MS satisfies the mode of the condition of being redirected, and can set according to actual needs.Consider whether FAP for the number of users quantitative limitation and for the protection of authorized user, preferably, can be authorized user according to the MS of current activation number of calls or judgement, judges whether said MS meets redirected condition.Particularly, when FAP is operated in non-open mode,, then adjudicates this MS and meet redirected condition if this MS is a unauthorized user; When FAP is operated in open mode and non-open mode, maximum if current excited user number reaches, then adjudicate this MS and meet redirected condition.
Certainly whether the above-mentioned MS that provides meets the concrete judgment mode of the condition of being redirected, and only is an example, in the practical application, can be redirected the setting of condition as required, does not do qualification here.
After judging that definite MS meets the condition of being redirected, carry out subsequent step and carry out redirect operation; After judging that definite MS does not meet the condition of being redirected, then need not carry out the re-orientation processes among the present invention, directly process ends.
After definite MS meets the condition of being redirected, no longer send page response to MSC.Like this,,, therefore, can directly not carry out assignment to MS, thereby paging failure and the call setup avoiding bringing are thus failed through FAP because MSC does not receive the page response that FAP sends for the MS that is redirected.
The processing of above-mentioned steps 206～208 is used for MS is redirected to adjacent macro base station, and sends location update request message by the macro base station that is redirected to MSC, thereby the position of this MS of notice MSC is upgraded.Processing that concrete above-mentioned steps 206～208 is redirected and the concrete mode of notice MSC are merely an example, also can adopt other processing to realize being redirected of MS and to the notice of MSC.
As previously mentioned, through step 206, for the paging of the MS that meets the condition of being redirected, FAP no longer sends page response to MSC.At this moment, MSC does not receive page response at the appointed time, and it is overtime paging to occur; Perhaps, before overtime, MSC detects the position of MS and upgrades (for example confirming the position renewal of MS through step 208); At this moment, MSC sends this MS of paging request message paging to grand BSS.
Through above-mentioned steps 210～212, MSC can arrive MS through grand BSS paging, and by the page response of grand BSS to MSC feedback MS, and begin normal called flow, connect.Like this and since MSC correctly from the grand BSS paging at MS place to MS, connect the success rate of setting up thereby improve.
So far, the called service reorientation method flow process of the embodiment of the invention finishes.As previously mentioned, the foregoing description is that example describes with 1X voice system under the CDMA Femto, and in fact; The said method flow process is suitable for for the communication system that other comprise Home eNodeB too; The message name that just wherein relates to is difference slightly, to those skilled in the art, can above-mentioned disclosed method flow process be applied to the communication system that other comprise Home eNodeB fully; Therefore comprise the idiographic flow in the communication system of Home eNodeB for other, just repeat no more here.
The present invention also provides a kind of Home eNodeB, can reduce the mortality that called service is redirected.Fig. 3 is the structure chart of Home eNodeB provided by the invention.As shown in Figure 3, the most basically, this Home eNodeB comprises redirected unit and interface unit.
Wherein, interface unit is used to receive the page response to the paging request and the said MS feedback of travelling carriage (MS) that MSC sends through femto gateway (FGW), and after receiving the page response of MS, notifies said redirected unit; Also be used for according to the notice that is redirected the unit, carry out or do not carry out the operation to MSC feedback page response through FGW.Be redirected the unit, whether the said MS of judgement meets redirected condition after receiving the notice of interface unit, if meet, then MS is redirected to adjacent macro base station, and the notification interface unit no longer feeds back page response through FGW to MSC; Otherwise the notification interface unit feeds back page response through FGW to MSC.
Further, when being redirected the concrete realization of unit, can comprising and be redirected judgement subelement and redirect operation subelement.Whether, according to current activation number of calls or MS be authorized user, judge whether MS meets redirected condition, and court verdict is sent to the redirect operation subelement if wherein, being redirected the judgement subelement, being used for after receiving the notice of interface unit.The redirect operation subelement is used for when MS meets the condition of being redirected, MS is redirected to adjacent macro base station, and the notification interface unit no longer feeding back page response through FGW to MSC; Also be used for when MS does not meet the condition of being redirected, the notification interface unit feeds back page response through FGW to MSC.
For being redirected the judgement subelement when being redirected judgement; The present invention provides two kinds of optional judgement modes; First kind: when FAP was operated in non-open mode, this was redirected the judgement subelement if confirm that MS is a unauthorized user, then adjudicates this MS and meets redirected condition.Second kind: when FAP was operated in non-open mode and non-open mode, this was redirected the judgement subelement and reaches maximum if confirm current excited user number, then adjudicates this MS and meets redirected condition.Certainly, above-mentioned two kinds of judgement modes are merely optional judgement mode, and those skilled in the art can be redirected judgement according to the actual requirements, as long as can realize being redirected judgement, the present invention does not do qualification for the judgement mode.
When being redirected MS, can realize redirect operation for the redirect operation subelement through directly sending professional redirect message to this MS.Certainly, above-mentioned only provide be merely a kind of optional redirected mode, can certainly adopt any feasible redirected mode, as long as the redirect operation subelement among the FAP of the present invention can be realized being redirected, do not do qualification for concrete redirected mode.
Concrete realization by the invention described above is visible; The reorientation method of the called service that the present invention provides and Home eNodeB; Existing procedure and Home eNodeB are optimized, can be reduced the mortality that called service is redirected, improve paging success rate and call setup success rate.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
