Abstract
The invention discloses a realizing method of both accessing a terminal and increasing terminal voice quality. The method comprises following steps: negotiating services between a terminal and a key station on a control communication channel and lowering the service quality according to capability levels of a supporting terminal which is corresponded with different coding and decoding algorithms by the key station and then enabling the terminal to be accessed into the key station according to the capability levels of the terminal from high to low. The method of the invention can both access the terminal and increase the terminal voice quality evenly, thereby old terminals with low terminal capability levels are accessed into a developed wireless communication system, and simultaneously the speech quality of majority of terminals with higher terminal capability levels can not be affected.
Description
Technical field
The present invention relates to access terminal (MS) and improve the technology of MS voice quality, relate in particular to a kind of taking into account and insert MS and the implementation method that improves the MS voice quality based on the control channel service negotiation.
Background technology
Along with the evolution development of wireless telecommunication system, the encoding and decoding technique of improvement has improved the code efficiency of channel, thereby can better service quality (QoS, Quality of Service) be provided for the MS that inserts wireless telecommunication system.With code division multiple access (CDMA) system is that example describes.At present, in cdma system, the business of the most often using is exactly speech business.Speech business has the multiple business option, and every kind of business option corresponding different QoS.Normally used business option comprises in the speech business: 8K, enhancement mode variable Rate encoding and decoding (EVRC; Enhanced Variable Rate Codec), the high make code of 13K is excited linear indication encoding and decoding (QCELP, Qualcomm Code Excited Linear Predictive Coding).Here, the corresponding different voice code decode algorithm of each business option difference.Such as business option is 8K, and the voice coding/decoding algorithms that this business option is corresponding is: encoding code stream speed is the code decode algorithm of 8K.
To the time that the corresponding voice coding/decoding algorithms of each business option occurs, the voice coding/decoding algorithms that 8K is corresponding occurs the earliest, is the corresponding voice coding/decoding algorithms of 13K QCELP then, is the corresponding voice coding/decoding algorithms of EVRC at last.The voice quality that provides to the corresponding voice coding/decoding algorithms of each business option; The voice quality that adopts the corresponding voice coding/decoding algorithms of 8K to provide is the poorest; Adopt the corresponding voice coding/decoding algorithms of EVRC to take second place, best is the voice coding/decoding algorithms that adopts 13K QCELP corresponding.Wherein, The voice quality that the voice coding/decoding algorithms that voice coding/decoding algorithms that EVRC is corresponding and 13K QCELP are corresponding can provide is more approaching; But compared to the corresponding voice coding/decoding algorithms of EVRC, the coding resource that the voice coding/decoding algorithms that 13KQCELP is corresponding needs is more; Therefore generally be the voice coding/decoding algorithms of recommending to adopt the EVRC correspondence at Commercial deployment, thereby the business option that adopts is EVRC.
For instance, the process that MS inserts cdma system is: in the call establishment of MS, MS can at first ask the business option of a first-selection, after base station (BS) receives the request of MS, can take following strategy so that insert MS.When the first-selected current business option of MS was 8K or EVRC, because the coding resource that their corresponding voice coding/decoding algorithms need is less, BS can satisfy the requirement of MS usually, need not carry out the service negotiation flow process; When the first-selected current business option of MS is 13K QCELP; Because the coding resource that the voice coding/decoding algorithms that 13K QCELP is corresponding needs is more, so BS will initiate the service negotiation flow process, and pass through service negotiation; With the current business option negotiation is EVRC or 8K, to guarantee the access of MS.
Yet the business option that usually adopts at Commercial deployment is under the situation of EVRC, in the application of actual Commercial deployment, but finds, also has a large amount of more old MS at present, can only supporting business option 8K or 8K/13K QCELP, do not support EVRC.To this MS, because BS can carry out service negotiation with MS, so caller is out of question.But for called be in-problem.
Below to above-mentioned old MS called in existing problem set forth.
In the CMDA system, during BS paging MS, generally take the strategy of fixed service option, just in beep-page message, the field of business option is extended this as EVRC.But to the old MS that does not support EVRC; MS is for the response of this beep-page message; Just the called of MS is generally: the one, and, page-response message is returned BS, and to be packaged with business option in this page-response message be 0; The expression refusal is current called, and the called failure of MS causes inserting MS; The 2nd,, page-response message is returned BS, and the business option that encapsulates in this page-response message is a selected substitution value of MS oneself, and current business option is EVRC, so the called same failure of MS, also can't insert MS.
So; Problem to the called failure of above-mentioned MS; Adopting prior art to solve can make BS be absorbed in an awkward predicament: if BS forces to remove paging MS with business option EVRC; Then, certainly will make old MS can not insert the CMDA system, thereby cause user's complaint just in case there is the old MS that only supports 8K; If BS forces to remove paging MS with business option 8k, then can success calling, but it is pointed out that whole to net voice quality be cost to reduce for this, cost is excessive, also possibly cause user's complaint; If be not with business option during the BS paging; Find in actual Commercial deployment that so it is the page-response message of 8K that script supports the MS of EVRC but to return business option; Can only enjoy the voice quality of 8K when causing supporting the MS of EVRC called; Can not give the user experience of well conversing equally, also might cause user's complaint.
In sum, only take into account and insert MS and improve the MS voice quality, just guarantee the call completion ratio of MS and the balance of whole net voice quality, could support on the basis that different business option MS inserts, bring the user experience of well conversing.Insert the CMDA system such as the MS that will support 8K/13K QCELP, simultaneously, make other users that support EVRC can also continue to enjoy the voice quality of EVRC.Can know from the above balance that cdma system, adopts prior art can't take into account and insert MS and improve the MS voice quality; Evolution development along with wireless telecommunication system; Though the encoding and decoding technique that improves can improve the code efficiency of channel, for the MS that inserts wireless telecommunication system provides better QoS; Because the superiority-inferiority of each encoding and decoding technique; And different encoding and decoding techniques corresponding support that the ability grade of MS is different, cause the low old MS of MS ability grade can't insert the wireless telecommunication system of evolution, have influence on the voice quality of the higher MS of other most MS ability grades simultaneously.
Summary of the invention
In view of this; Main purpose of the present invention is to provide a kind of taking into account to insert MS and the implementation method that improves the MS voice quality; Can take into account and insert MS and the balance that improves the MS voice quality; Thereby make the low old MS of MS ability grade can insert the wireless telecommunication system of evolution, the while can not have influence on the voice quality of the higher MS of other most MS ability grades.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of taking into account inserted MS and the implementation method that improves the MS voice quality, and this method comprises: BS carries out the service negotiation between MS and the said BS and reduces service quality at control channel according to the ability grade of the corresponding support MS of different code decode algorithms institute; Afterwards, the ability grade according to said MS makes MS insert BS from high to low; Wherein, this method is specially:
A1, said BS send to current MS with beep-page message, and are packaged with the ability grade that current code decode algorithm is supported MS in the said beep-page message;
After A2, said current MS receive said beep-page message, parse the ability grade that said current code decode algorithm is supported MS, and with the ability grade coupling of current MS;
If coupling then inserts current MS; Otherwise current MS will the information of not matching be encapsulated into and returns said BS in the page-response message, after BS receives page-response message; Judge that this paging is a speech business, current code decode algorithm is not supported at current terminal simultaneously, and current terminal is discharged into idle condition; Reduce service quality; Initiate paging for the second time, and the ability grade of the MS that code decode algorithm is supported that matees is encapsulated in the beep-page message, again current MS is carried out the access that paging realizes current MS.
Wherein, said current code decode algorithm supports that the ability grade of MS is a business option, and this method is: said BS starts the secondary beep-page message that is packaged with the different business option, the access of the MS that the fulfillment capability rank is low.
Wherein, BS starts the secondary beep-page message that is packaged with the different business option, and the access of the MS that the fulfillment capability rank is low is specially: said BS is encapsulated into default business option=EVRC earlier and removes the said current MS of paging in the said beep-page message; Current MS receives said beep-page message, and the business option that business option EVRC that discovery parses and current MS can support does not match, and in page-response message, filling in the information of not matching is to return to BS behind first-selected business option=0; BS starts paging for the second time, and business option 8K is encapsulated into removes the current MS of paging in the beep-page message; Current MS returns normal page-response message after receiving the corresponding beep-page message of the said paging second time, and encapsulated information is first-selected business option=8K in the said normal page-response message.
The present invention is through the service negotiation between MS and BS; Particularly be different from the service negotiation that has now in Traffic Channel; Service negotiation between MS and the BS carries out at control channel; Can take into account and insert MS and the balance that improves the MS voice quality, thereby make the low old MS of MS ability grade can insert the wireless telecommunication system of evolution, the while can not have influence on the voice quality of the higher MS of other most MS ability grades.To service negotiation; BS in the wireless telecommunication system can according to different encoding and decoding techniques the corresponding ability grade of supporting MS; Through and MS between service negotiation reduce QoS, the ability grade access MS from high to low according to MS provides service for the user as far as possible.For instance; If the code decode algorithm that wireless telecommunication system is current corresponding support that the ability grade of MS is high; And this system of MS that can this ability grade is high access, high QoS is provided for simultaneously the high MS of this ability grade, the MS that so current capable rank is low will insert this system; Can only be through behind this ability grade low MS and the reduction of the service negotiation between BS QoS, MS that could this ability grade is low inserts this system.And the current code decode algorithm that need to adopt is corresponding with the low MS of this ability grade.In sum, adopt new business in the wireless telecommunication system the invention solves evolution from now on use and old MS between compatibility.

Embodiment
Core concept of the present invention is: the present invention is through the service negotiation between MS and BS; Particularly be different from the service negotiation that has now in Traffic Channel; Service negotiation between MS and the BS carries out at control channel; Can take into account and insert MS and the balance that improves the MS voice quality, thereby make the low old MS of MS ability grade can insert the wireless telecommunication system of evolution, the while can not have influence on the voice quality of the higher MS of other most MS ability grades.
Below in conjunction with accompanying drawing the enforcement of technical scheme is done further to describe in detail.
A kind of taking into account inserted MS and the implementation method that improves the MS voice quality, and the method comprising the steps of: BS carries out the service negotiation between MS and the BS and reduces service quality at control channel according to the ability grade of the corresponding support MS of different code decode algorithms institute; Afterwards, the ability grade according to MS makes MS insert BS from high to low.
As shown in Figure 1, a kind of implementation method that inserts MS and raising MS voice quality of taking into account specifically may further comprise the steps:
After step 102, current MS receive this beep-page message from BS, parse the ability grade that current code decode algorithm is supported MS, and with the ability grade coupling of current MS, if coupling, then execution in step 103; Otherwise, execution in step 104.
Method embodiment one is: in cdma system, current code decode algorithm supports that the ability grade of MS is business option EVRC, and the ability grade of paged MS is lower, supports the ability grade of MS not match with current code decode algorithm.And with the ability grade ability grade that be complementary, MS that code decode algorithm is supported of paged MS be business option 8K.In the present embodiment, taking into account and inserting MS is to start the secondary paging that is packaged with the different business option through BS with the implementation method that improves the MS voice quality, and the realization business option is that the MS of 8K inserts CDMA's.The realization flow of present embodiment may further comprise the steps:
Step 201, mobile switching centre (MSC, Mobile Switch Center) initiate paging request for the first time, after BS receives the paging request first time, carry out necessary bookkeeping work, just note the information relevant with this time paging request.
Step 202, BS are encapsulated into default business option=EVRC earlier and remove paging MS in the beep-page message.MS receives this beep-page message, and the business option that the business option EVRC that discovery parses and this MS can support does not match, and in page-response message, filling in the information of not matching is to return to BS behind first-selected business option=0.
Step 203, BS reply after receiving this page-response message, and return a base station confirmation instruction.
Here, this base station confirmation instruction also is appreciated that and is the response message to this page-response message.This base station confirms that instruction is used to indicate BS to receive the page-response message that this MS sends, and informs that MS need not to have redispatched page-response message.If the unresponsive words of BS, MS can constantly send page-response message.
Step 204, BS judge that this paging is a speech business, and while MS is supporting business option EVRC not, sends this MS that releases order, and MS is discharged into idle condition.
Step 205, BS are initiated paging for the second time, and business option 8K is encapsulated into removes paging MS in the beep-page message; MS has returned normal page-response message after receiving the corresponding beep-page message of this paging second time, and encapsulated information is first-selected business option=8K in this normal page-response message.Afterwards, MS carries out normal page response access process, normally gets into talking state then.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
