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 implementation method that inserts MS and improve the MS voice quality of taking into account 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 provide better service quality (QoS, Quality ofService) 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 normal use is exactly speech business.Speech business has the multiple business option, and every kind of business option correspondence 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 respectively voice coding/decoding algorithms of each business option.Such as business option is 8K, and the voice coding/decoding algorithms of this business option correspondence is: encoding code stream speed is the code decode algorithm of 8K.
At the time that the corresponding voice coding/decoding algorithms of each business option occurs, the voice coding/decoding algorithms of 8K correspondence occurs the earliest, is the voice coding/decoding algorithms of 13K QCELP correspondence then, is the voice coding/decoding algorithms of EVRC correspondence at last.The voice quality that provides at the corresponding voice coding/decoding algorithms of each business option, the voice quality that the voice coding/decoding algorithms of employing 8K correspondence can provide is the poorest, adopt the voice coding/decoding algorithms of EVRC correspondence to take second place, best is the voice coding/decoding algorithms that adopts 13K QCELP correspondence.Wherein, the voice quality that the voice coding/decoding algorithms of the voice coding/decoding algorithms of EVRC correspondence and 13K QCELP correspondence can provide is more approaching, but, voice coding/decoding algorithms compared to the EVRC correspondence, the coding resource that the voice coding/decoding algorithms of 13KQCELP correspondence 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 current business option of MS first-selection was 8K or EVRC, because the coding resource that the voice coding/decoding algorithms of their correspondences needs is less, BS can satisfy the requirement of MS usually, does not need to carry out the service negotiation flow process; When the current business option of MS first-selection is 13K QCELP, because the coding resource that the voice coding/decoding algorithms of 13K QCELP correspondence 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, but finds in the application of actual Commercial deployment, 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.At 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 at 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,, page-response message is returned BS, and being packaged with business option in this page-response message is 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 at 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 just in case there is the old MS that only supports 8K, certainly will make old MS can not insert the CMDA system, thereby cause user's complaint; If BS forces to remove paging MS with business option 8k, then can the paging success, but it is pointed out that to put in order the net voice quality be cost to reduce for this, cost is excessive, also may 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.From the above balance that cdma system, adopts prior art to take into account to insert MS and improve the MS voice quality as can be known, 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, but, because the superiority-inferiority of each encoding and decoding technique, and different encoding and decoding techniques the corresponding ability grade difference of supporting MS, 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 implementation method that inserts MS and improve the MS voice quality of taking into account, can take into account the balance that inserts MS and improve 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

Wherein, this method is specially:
A1, described 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 described beep-page message;
After A2, described current MS receive described beep-page message, parse the ability grade that described 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 described BS in the page-response message, BS reduces service quality, and the ability grade of MS that code decode algorithm is supported of coupling is encapsulated into during paging disappears, and again current MS is carried out the access that paging realizes current MS.
Wherein, described current code decode algorithm supports that the ability grade of MS is a business option, and this method further is: described 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:
Described BS is encapsulated into default business option=EVRC earlier and removes the described current MS of paging in the described beep-page message; Current MS receives described 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 beep-page message of described paging second time correspondence, and encapsulated information is first-selected business option=8K in the described normal page-response message.
The present invention is by 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 the balance that inserts MS and improve 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.At service negotiation, BS in the wireless telecommunication system can according to different encoding and decoding techniques the corresponding ability grade of supporting MS, by 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 the corresponding ability grade height of supporting MS, and can insert this system by the MS that this ability grade is high, 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 could insert this system by the MS that this ability grade is low by behind this ability grade low MS and the reduction of the service negotiation between BS QoS.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.
