Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method and device of switch mode conversion.
Background technology
At present many communication systems have all been used local function of exchange.Local exchange refers to that the calling and called user is meeting under the certain condition, and core net is no longer passed through in its conversation (user face data just), and the mode of directly between two base stations of calling and called, carrying out.The benefit of doing like this is, reduced the taking of resources of core network, and shortened the propagation delay time of voice.Saved Abis mouth utilized bandwidths such as (interfaces between base station and the base station controller), for operator and user provide convenience.The maximum characteristics of local exchange are: user face data no longer transmits via core net and directly carries out between the base station.When conversation adopts aforesaid way to transmit, think under local switch mode, to carry out, corresponding, traditional talking mode is then thought and is carried out under the traditional exchange pattern.
Local switch mode is a kind of special applications of legacy communications system, saved the bandwidth resources of Abis mouth etc. greatly, but also certainly will introduce new problem.Because in mobile communication, a large amount of switchings is necessarily arranged, to consider more factors in the switching of local switch mode, inevitable some new Performance Influence Factor of also just bringing.For example, two users that converse under local switch mode may be because the switching back changes because of channel type or because switching the variation of base station, place, back, therefore needs are transformed under the traditional call pattern so no longer meet the local condition that exchanges.And switch frequently, what may cause does not still switch frequently, and with conversion (conversion between traditional exchange pattern and local switch mode) frequently; Moreover the switching under local switch mode for example, is used for the situation that service channel new between the base station of local exchange is set up also because will take into account the consideration more factors.Like this, the stability of the switching under the local switch mode is obviously than the switching poor stability under the traditional exchange pattern.
In addition; in the conversation of local switch mode; the user usually can use supplementary services such as some customer call maintenances; at this moment, also need to return again under the traditional exchange pattern from local switch mode and carry out, after supplementary service is finished, return again under the local switch mode; obviously also can influence communication effect; even, when conversion is not smooth, possible call drop.
Obviously, when using the traditional exchange pattern, the stability of user's voice and business function rich more, better effects if.
As seen, use local switch mode can save the Abis port band width greatly, and use the traditional exchange pattern, can guarantee the maximum rich of the stability of user speech and business function.
Such situation is often arranged in the existing practice: given bandwidth is necessarily used, but the upper limit is limited, when conversation is busy, and can be because of pre-assigned limited bandwidth, so the phenomenon of phone occurs putting through, family or enterprise application more commonly.In the today that has local exchange to use, the conversation that can select to carry out local exchange by making all changes local switch mode over to, can solve the limited problem of bandwidth like this.But local exchange at present is dumb to the support of supplementary service, even may not advance to support supplementary service, so cause the use of calling user limited.The place that these needs that become local exchange application improve, and this is the advantage of traditional exchange pattern.
Existing common processing mode is, meet the just conversion of local exchange switch condition, for conserve bandwidth is carried out this locality exchange conversion, but this moment, can there be a lot of inconvenience in processing to supplementary service, even may not carry out supplementary service, and supplementary service to be applied in current be commonplace also, so can produce many problems.Therefore, under the bandwidth restricted condition, how to take full advantage of the superiority bandwidth of local exchange and the voice under the traditional exchange pattern are stable and business is enriched advantage, being one has problem to be solved.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is: under the bandwidth confined condition, take full advantage of advantage and the stable and professional greatly abundant advantage of the voice under the traditional exchange pattern of conserve bandwidth under the local switch mode, to improve whole call performance.
In order to solve the problems of the technologies described above, one aspect of the present invention provides a kind of method of switch mode conversion, comprising: detect Abis mouth remaining bandwidth; Local switch mode switching threshold and traditional exchange pattern switching threshold are set; When remaining bandwidth during greater than described traditional exchange pattern switching threshold, current talking is converted to the traditional exchange pattern from local switch mode; When remaining bandwidth during less than local switch mode switching threshold, current talking is converted to local switch mode from the traditional exchange pattern.
Further, when remaining bandwidth greater than described local switch mode switching threshold, and during less than traditional exchange pattern switching threshold, then current talking is not carried out the pattern conversion.
Further, the more described remaining bandwidth of real-time judge and described local switch mode switching threshold and traditional exchange pattern switching threshold.
Further, described detection remaining bandwidth comprises: when pattern is changed successfully, or conversation is set up or when discharging, Query Database obtains up-to-date remaining bandwidth resource information in real time.
Further, current talking is converted to local switch mode from the traditional exchange pattern before, further comprising the steps of: judge whether current talking satisfies local give-and-take conditions, satisfied then current talking is converted to local switch mode from the traditional exchange pattern.
Further, when being converted to local switch mode from the traditional exchange pattern, the user's communication that priority is high, or carried out the conversation of supplementary service, preferentially remain under the traditional exchange pattern; When being converted to the traditional exchange pattern from local switch mode, preferentially changing the high user's communication of priority or carried out the conversation of supplementary service.
The present invention provides a kind of device of switch mode conversion on the other hand, comprising: remaining bandwidth detection module 100, for detection of Abis mouth remaining bandwidth; Thresholding arranges module 500, is used for arranging local switch mode switching threshold and traditional exchange pattern switching threshold; Conversion and control module 200 when remaining bandwidth during greater than described traditional exchange pattern switching threshold, is converted to the traditional exchange pattern with current talking from local switch mode; When remaining bandwidth during less than local switch mode switching threshold, current talking is converted to local switch mode from the traditional exchange pattern.

Embodiment
The present invention proposes and a kind ofly utilize situation to regulate the processing method that traditional exchange pattern and local switch mode are changed according to the Abis port band width, basic principle of the present invention as shown in Figure 1: when bandwidth was rich, conversation was transformed under the traditional exchange pattern; When bandwidth was not enough, conversation was transformed into local switch mode.
Fig. 2 is method flow diagram of the present invention, and as shown in Figure 2, the basic skills flow process is: detect Abis mouth remaining bandwidth; Local switch mode switching threshold and traditional exchange pattern switching threshold are set; When remaining bandwidth during greater than described traditional exchange pattern switching threshold (upper limit), conversation under the local switch mode is transformed under the traditional exchange pattern, when remaining bandwidth less than local switch mode switching threshold (lower limit), the conversation under the traditional exchange pattern is transformed into local switch mode.
Wherein, when between local switch mode and traditional exchange pattern, changing, no matter be that thataway transforms, all can progressively affect the size of remaining bandwidth along with the carrying out of conversion, therefore, be to need in time and dynamic to the detection of remaining bandwidth.When selecting converting objects (conversation just) (no matter being towards local change of direction conversion or towards the conversion of traditional exchange direction), can adopt the mode of picked at random, or the mode of employing User Priority, or the conditions of demand of supplementary service are chosen according to the user, or the combination of above multiple mode.
Fig. 3 is module logic diagram of the present invention, as shown in Figure 3, comprises remaining bandwidth detection module 100, conversion and control module 200, and call mode modular converter 300 and conversation are set up and release module 400.
Remaining bandwidth detection module 100: be used for according to present case, inquire about in real time, in time carry out resource control and handle.This module is in time obtained the remaining bandwidth resource information according to current talking flow process situation, and in time be notified to the conversion and control module carry out related procedure control, to reach the adjusting purpose.
As shown in Figure 3, remaining bandwidth detection module 100 can in time obtain call mode flow path switch 300 and conversation and set up and release flow process 400 information, is convenient to detect timely according to the flow process situation.Such as, after a conversation foundation was finished, module 100 can be received to converse to set up and finish message, so the timely current up-to-date remaining bandwidth resource situation of Query Database.Perhaps when a conversation on-hook discharged, module 100 can be received the conversation release message, so the current up-to-date remaining bandwidth resource situation of Query Database again.During conversation keeps, when successfully changing local switch mode over to when conversing, module 100 also will be received pattern conversion success message, the timely current up-to-date remaining bandwidth resource situation of Query Database, and when successfully being transformed into the traditional exchange pattern again when conversing, module 100 also will be received pattern conversion success message, the still timely current up-to-date remaining bandwidth resource situation of Query Database.Therefore can detect current up-to-date remaining bandwidth resource situation in time and flexibly, delicately.
Conversion and control module 200: according to remaining bandwidth detection module 100 detected up-to-date remaining bandwidth information, compare with local switch mode switching threshold and traditional exchange pattern switching threshold.According to detection case, carry out switch decision.When confirming to carry out the AD HOC conversion to conversation, also to adopt ad hoc rules to choose converting objects (conversation), initiate conversation switch mode flow path switch according to particular step then.Here conversion is divided into both direction: local switch mode direction and traditional exchange pattern direction.
Call mode modular converter 300: realize realization flow and mechanism that conversation is changed between local switch mode and traditional exchange pattern.This flow process has not only been finished the desired patterns conversion of conversion and control module 200, and, complete successfully by message in conversion and in time to notify remaining bandwidth detection module 100.
Conversation is set up and release module 400: finished foundation and the release of conversing, setting up successfully or discharging when finishing, in time notified remaining bandwidth detection module 100.Simultaneously, ticketed call service conditions also, Client-initiated is professional to be supplementary service when (supplementary service needs the core net support) when being checked through, conversation is listed in outside the convertible object range at this point, allows it remain under the traditional exchange pattern.Certainly, some business is just initiated during conversing, such as, the user has initiated supplementary service during the conversation, and at this moment, therefore conversation may, need be transformed under the traditional exchange pattern and just can carry out supplementary service under local switch mode.And to parsing and the detection of this type of service, also carry out in this module this moment.
Fig. 4 is remaining bandwidth detection module figure, as shown in Figure 4, remaining bandwidth detection module 100 obtains trigger message from call mode flow path switch 300 and conversation foundation and release flow process 400, comprise: message, conversation release message are set up in conversation, or obtain converting message etc., timely Query Database, and data are in time offered conversion and control module 200.
When changing the traditional exchange pattern in conversation foundation or with the conversation under the local switch mode, can cause the minimizing of remaining bandwidth resource; Discharge or conversation is transferred to local switch mode following time in conversation, can cause the increase of remaining bandwidth resource.Both of these case remaining bandwidth detection module 100 will detect and in time notify conversion and control module 200 neatly.
Fig. 5 is the thresholding key diagram that relates in the conversion and control module 200.
As shown in Figure 5, the longest straight line is represented the remaining bandwidth resource, when conversion and control module 200 finds that the remaining bandwidth resource is higher than traditional exchange switching threshold (the abbreviation upper limit), shows that surplus resources is abundant, therefore, can consider very much the saving of Abis resource.Therefore, if having the conversation that exists in the conversation under the local switch mode now, can be transferred to this or these conversation successively under the traditional exchange pattern and carry out, so initiate the pattern flow path switch one time.When conversion and control module 200 finds that the remaining bandwidth resource is lower than local exchange switching threshold (abbreviation lower limit), show that surplus resources is fewer, if there is the conversation under the traditional exchange pattern in the existing conversation, can be transferred to this or these conversation successively under the local switch mode and carry out, so initiate the pattern flow path switch one time.
Particularly, can be by threshold value arrange to regulate converting sensitivity.Such as, when lower limit arrange more high, just when surplus resources is relatively rich, also can carry out this locality early and exchange and change; Otherwise setting more low just just begins conversion when surplus resources is relatively poor.Same reason, when the upper limit arrange more low, illustrate and also can change early to the traditional exchange pattern in the bandwidth surplus relatively not for a long time that perhaps setting is more high, explanation must be changed to the traditional exchange pattern in the bandwidth surplus more for a long time; If but too sensitive, may will cause changing frequently, therefore need adjust in conjunction with actual.
Fig. 6 selects the converting objects flow chart, as shown in Figure 6, know the remaining bandwidth resource situation after, judge according to default local switch mode switching threshold and traditional exchange pattern switching threshold, draw conversion direction after the judgement.Determine that according to conversion direction the conversion selection criterion selects the object that will change then, initiate corresponding flow path switch then.
Conversion selection criterion 1: the criterion that is transformed into local switch mode from the traditional exchange pattern:
1) present user under the traditional exchange pattern;
Shown it is the conversation of supplementary service during 2) to initiation, do not carried out the pattern conversion, remained under the traditional exchange pattern;
3) to carrying out the conversation of supplementary service in the conversation, preferentially remain under the traditional exchange pattern as far as possible;
4) user that priority is high preferentially remains under the traditional exchange pattern as far as possible;
5) to the conversation of no special circumstances, the conversion from the traditional exchange pattern to local switch mode is carried out in selection at random.
Conversion selection criterion 2: the criterion that is transformed into the traditional exchange pattern from local switch mode:
1) present user under local switch mode;
2) conversation of supplementary service was once done in preferential conversion;
3) the preferential high conversation of converting users priority;
4) as there not being above-mentioned situation, picked at random is changed.
Fig. 7 has described record supplementary service initiation situation sign in conversation foundation and the release module 400, is convenient to change the judgement of selection criterion.As shown in Figure 7,
Situation one:
Step 1: conversation is set up and is discharged flow process 400 and detects new talk business initiation.

Step 1: conversation is set up and release module 400 detects new talk business initiation.
Step 2: find in conversation foundation and the release module 400 that conversation is the general service type.
Step 3: during the conversation, the parsing that conversation is set up and release module 400 is passed through professional solicitation message finds to require the application supplementary service, this type of service is recorded in the professional addition type sign of the buffer area in the module 400.
In situation 1, because known it is the supplementary service application when initially setting up in conversation, therefore, not as converting objects, namely under the traditional exchange pattern, do not change, that is to say that two switching criterions are not used.
In situation 2, in the conversation of application conversation general service is carried out, when not receiving supplementary service request as yet during this time, can be when bandwidth conversion needs, usage criteria 1 selects suitable conversation to be converted to local switch mode, but in local switch mode following time, when finding the supplementary service application is arranged, at once pass criteria 2 to select suitable conversation to be transformed under the traditional mode in this conversation.
