Abstract

The method includes following steps: a) in paging process the called VLR receives request for providing roaming number for called HLR; b) the called VLR sends out pre-paging through MSC in call area where the called party is at and decides if it is succeeded, if yes, then entering into step d, otherwise entering into step c; c) it is decided if the called subscriber enables the follow-on-call in the end office according to cause of failure, if yes, then entering into step d, otherwise entering into step e; d) the called VLR returns successful response to called HLR and continues normal process, then ending; e) the called VLR returns failure response to the called HLR and makes process according to cause of failure, then ending.

Description

A kind of implementation method of optimizing the mobile subscriber as called flow

Technical field

The present invention relates to the call business in the moving communicating field, relate in particular to the call flow of mobile subscriber when called.

Background technology

The normal flow that GSM09.02 protocol description mobile subscriber does when called is, GMSC (GatewayMobile Switching Center: gateway MSC) obtain roaming number by route information query, according to roaming number, GMSC is called to the MSC at called place, and (Mobile SwitchingCenter: mobile switching centre), this MSC carries out called subscriber's paging more then.

There is certain defective in this flow process, for example the called subscriber is in the blind area of wireless signal and can't connect the time, GMSC also can arrive called VMSC to follow-up call as usual, and (Visited MSC: visit ground mobile switching centre), VMSC carries out paging more then, but final calling still ends in failure.Like this, when the called subscriber can't call accepted, network also carried out call proceeding and redundantly to called processes such as paging.This has not only wasted the traffic resource between GMSC and the VMSC and has sought the Radio Resource of base station when crying, and has prolonged the whole response time of exhaling.

Summary of the invention

Technical problem to be solved by this invention provides the implementation method of a kind of mobile subscriber of optimization as called flow, can avoid called subscriber's unnecessary continuing and paging operation of network can't call accepted the time.

In order to solve the problems of the technologies described above, the invention provides the implementation method of a kind of mobile subscriber of optimization as called flow, may further comprise the steps:

(a) in the paging, called VLR Visitor Location Register is received the request that called attaching position register Provides Roaming Number;

(b) called VLR Visitor Location Register sends pre-paging by the mobile switching centre of called place calling zone to the called subscriber, and judges whether success, if success, execution in step (d), otherwise, carry out next step;

(c) judge according to failure cause whether the called subscriber has activated the business that continues calling in this called VLR Visitor Location Register place end office (EO), if, carry out next step, otherwise execution in step (e);

(d) called VLR Visitor Location Register returns the success response that Provides Roaming Number to called attaching position register, continues the flow process of agreement regulation, finishes;

(e) called VLR Visitor Location Register returns the failure response that Provides Roaming Number to called attaching position register, handles according to failure cause, finishes.

Further, in order to reduce the ineffertive pager of system, described optimization mobile subscriber also comprises step afterwards as the described step (a) of the implementation method of called flow:

(a1) called VLR Visitor Location Register judges whether the user is in busy condition and busy time less than set point, if, carry out next step, otherwise execution in step (b);

(a2) check whether the user has activated the business that continues calling when doing in this end office (EO) of meeting, if, execution in step (d), otherwise execution in step (e).

Further, described optimization mobile subscriber can have following characteristics as the implementation method of called flow: described step (c) judge user's un-activation this end office (EO) continue to call out professional the time, in execution in step (e) before, carry out following steps earlier: judge according to failure cause whether the called subscriber has activated the business that the office's of striding continuation is called out, if, the failure cause that returns in step (e) is the absent subscriber, otherwise returns the failure cause in the pre-call response.

Further, described optimization mobile subscriber can have following characteristics as the implementation method of called flow: in the described step (e), when handling according to failure cause, if called subscriber's un-activation the business that the office of striding continue to call out under this failure scenarios, then finish whole calling.

As from the foregoing, the inventive method in sum, the inventive method by to called subscriber's chance busy check and paging in advance, make network find that in time can the called subscriber call accepted, timely end call process when the called subscriber can't call accepted.Thereby avoided unnecessary continuing and operation such as paging in the call flow of protocol description, receive the raising percept of call completed, reduced turn-on time and improved effects such as wireless resource utility efficiency.Simultaneously paging is shifted to an earlier date, also, improved the CAMEL business for the CAMEL business provides higher positional information and state information.

Embodiment

Present embodiment has adopted the method for pre-paging, promptly when receiving the roaming number that attaching position register (HLR) provides, do not return the roaming number response immediately at VLR Visitor Location Register (VLR), but in the GSM0902 agreement on the basis of normal process with the process of paging in advance, if Called Busy or paging failure and not activating changes before corresponding or during latency services, this VLR returns the failure response that Provides Roaming Number to this HLR.Thereby avoided called subscriber's unnecessary continuing of network can't call accepted the time.Following VLR and HLR all refer to called VLR and HLR.

When going out to exhale or go into to exhale, when VLR finished signal to MSC transmission call request, setting and recording user state were busy; When calling out release, CC (Call Control: call out control) notify the user spare time; VLR is provided with and the recording user state spare time.For the ineffertive pager of further minimizing system, present embodiment is according to the statistical value of average holding time, and the set point of a busy time of configuration in VLR was as 1 minute.So a mobile subscriber as called communication process in, mobile subscriber's when called (when VLR receives the request that Provides Roaming Number of HLR) again within 1 minute, just think that the busy time is less than set point, if user's un-activation divert when busy and activation Call Waiting, VLR is not to the MSC paging, provide MSRN (Mobile Subscriber Roaming Number, Mobile Station Roaming Number) failure and return to HLR.Probably account for 90% because generally make a phone call greater than 1 minute people, thereby can significantly reduce the ineffertive pager of system.

Fig. 1 shows present embodiment optimization mobile subscriber as called handling process, mainly is the called VLR processing procedure when distributing roaming number, as shown in the figure, may further comprise the steps:

Step 110, in the calling procedure, VLR receives that the MSRN that provides that HLR sends asks;

Step 120 judges whether the user is in busy condition and busy time less than set point, if, carry out next step, otherwise execution in step 140;

Step 130 checks whether the user activates divert when busy or call waiting, if, execution in step 180, otherwise execution in step 190;

Step 140, network side MSC/VLR initiates pre-paging (or crying pre-the search) request, and wait-for-response;

Step 150, VLR judges whether success after receiving the pre-paging response, if success, if execution in step 180 unsuccessful, is carried out next step;

Step 160, judge according to failure cause whether the called subscriber has activated the business that the landing office continuation is called out, present embodiment is to judge that whether failure cause is commentaries on classics before the busy and user of the user of network decision has contracted when busy, perhaps for calling out again and contracted Call Waiting and calling out of user keeps, perhaps be no-response paging and the user unreachable preceding commentaries on classics of landing of having contracted, if, execution in step 180, otherwise carry out next step;

Step 170, judge according to failure cause whether the called subscriber has activated the office of striding and continued the business of calling out, present embodiment is to judge that whether failure cause is no-response paging and the user commentaries on classics before the unreachable HLR of having contracted, if, execution in step 200, otherwise execution in step 190;

Step 180, returning to HLR provides MSRN success response, continues gsm protocol predetermined process flow process, finishes;

Step 190, returning to HLR provides MSRN failure response, finishes whole calling (also being the flow process of agreement regulation);

Step 200, returning to HLR provides MSRN failure response, and failure cause is the absent subscriber, continues gsm protocol predetermined process flow process, finishes.

Need to prove that if because the user is busy and the busy time is activated the related service that continues calling again less than set point, the failure cause that step 190 is returned is system mistake; Continue the related service called out if pre-paging failure and not having activates at landing office, the failure cause that step 180 is returned is the failure cause in the pre-call response.

In sum, the inventive method by to called subscriber's chance busy check and paging in advance, make network find that in time can the called subscriber call accepted, timely end call process when the called subscriber can't call accepted.Thereby avoided unnecessary continuing and operation such as paging in the call flow of protocol description, receive the raising percept of call completed, reduced turn-on time and improved effects such as wireless resource utility efficiency.Simultaneously paging is shifted to an earlier date, also, improved the CAMEL business for the CAMEL business provides higher positional information and state information.

The method that the present invention proposes generally is suitable for mobile communications network, in mobile communications networks such as CDMA, UMTS.In addition, whether continue the relevant business of call flow can't call accepted the time and may constantly occur, be not limited to several situations cited among the embodiment with called.

Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, technical scheme of the present invention is made amendment or is equal to replacement, and do not break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
