Description
Technical field
The present invention relates to the communications field, in particular to a kind of processing method of notification configuration frame and pattern transducer and Rate Adapter Unit (Transcoder and Rate AdaptorUnit, referred to as TRAU).
Background technology
In traditional mobile communication system, call out between travelling carriage (Mobile Station, referred to as MS), need the cascade operation carrying out twice encoding and decoding speech on whole transmission link, therefore can reduce voice quality.In order to address this problem, tandem free cascade operation (Tandem Free Operation is proposed in correlation technique, referred to as TFO), this TFO can make the cascade operation reducing by an encoding and decoding speech in transmitting procedure, thus improves voice quality.
At global mobile communication (Global system for Mobile Communication, referred to as GSM) in system, adaptive multi-rate (Adaptive Multi-Rate is used between MS, referred to as AMR) algorithm time, if need to set up TFO, then need to be undertaken alternately by notification configuration frame between TRAU and base station (Base Transceiver Station, referred to as BTS).
Specifically, when TFO prepares to set up, advanced scanning frequency rate adjustment, TRAU sends the TFO_SOON notification configuration frame carrying rate adjustment request to BTS, to notify that BTS enters TFO_Maybe state, scanning frequency of going forward side by side rate adjusts.Then, after completing speed adjustment, BTS also replys Rc_Ack to TRAU and configures frame.Only after TRAU receives Rc_Ack, the TFO in TRAU just can enter next TFO state, namely starts to send TFO frame to opposite end TRAU, and sets up TFO.
Specifically describe TRAU and BTS below and carry out mutual process by notification configuration frame.
First, the relevant configured parameter of AMR sends to TRAU by BTS in real time, holds consultation with the TFO activated in TRAU.
Then, TRAU sends the state information of TFO, with the TFO state consistency of the TFO state and BTS that keep TRAU to BTS.
In addition, the notification configuration frame type of interaction between above-mentioned TRAU and BTS is as shown in table 1 below.The TFO state that TRAU sends to BTS comprises three types: TFO_OFF (namely TFO closes notification configuration frame), TFO_SOON (namely TFO prepares notification configuration frame) and TFO_ON (namely TFO opens notification configuration frame).Wherein, BTS replys at once when receiving TFO_OFF notification configuration frame and TFO_ON notification configuration frame; When receiving TFO_SOON notification configuration frame, first BTS enters TFO_Maybe state, replys TRAU again after speed adjustment to be done.It should be noted that, BTS is concerning the response of TFO_SOON notification configuration frame for being a crucial event TFO, and only create this event, TFO sets up and could continue, and therefore, TRAU has very high expectation to this event.
The signal table of the notification configuration frame type of interaction between table 1TRAU and BTS
| Notification configuration frame type | Possible containing type | Location | Effect | Transmitting terminal | Receiving terminal |
| Con_Req | Switching notice, Handover_SOON, Handover_Complete | Up, descending | Parameter is mutual, requires to reply | BTS | BTS or TRAU |
| Dis_Req | TFO notifies, TFO_ON, TFO_OFF, TFO_SOON | Up, descending | Carry configuration parameter or the reply of TFO notice request | TRAU | BTS |
| Con_Ack | - | Descending | The reply of Con_Req | BTS | BTS or TRAU |
| UL_Ack | The reply of TFO notice | Up TRAU frame | The reply of Dis_Req | BTS | TRAU |
| DL_Ack | - | Descending TRAU frame | The reply of Con_Req | TRAU | BTS |
Below above-mentioned notification configuration frame is described in detail.
Notification configuration frame is usually divided into claim frame and replys frame, and TRAU and BTS will wait for reply after sending claim frame, all will reply receiving claim frame.Meanwhile, if transmitting terminal does not receive reply frame in certain hour after sending claim frame, this claim frame will be retransmitted.When carrying out voice call, because this notification configuration frame sends by stealing frame, and repeatedly re-send request may frame will affect voice call quality, therefore, specify in agreement 28.062-810, if transmitting terminal does not still receive reply frame after repeating transmission three claim frames, then TFO just will enter FAI state, namely cause TFO failure.
It should be noted that, the time that TRAU retransmits needed for three claim frames is not long, and for the notification configuration frame requiring to reply at once, this time usually can as judging the mutual failed thresholding of link.
But when BTS has needed speed adjustment to reply, the time that the regulation time needed for it retransmits three claim frames relative to TRAU is just long.If the time that BTS completes speed adjustment is slightly long, cause TRAU retransmit three claim frames after still do not receive reply frame, then TFO just will enter FAI state, namely cause TFO unsuccessfully, TFO function can not be brought into play effectively.
In addition, TFO_OFF can represent the notice that TFO does not set up, and at this moment TRAU is in the state of non-TFO, needs as early as possible this message to be notified base station, makes TRAU and BTS all be synchronized to the conventional process state of non-TFO.If cannot send, TRAU can be caused to terminate TFO, and base station also may be in the state of TFO_Maybe or TFO_Yes, namely the TFO state of base station and TRAU is inconsistent.

Step S104, TRAU determine to prepare, in notification configuration frame process, not receive the reply frame from BTS at the TFO sending pre-determined number.
Step S106, TRAU indicate its TFO to enter wait state.
Pass through above-mentioned steps, in the TFO_SOON notification configuration frame process sending pre-determined number, when TRAU does not receive the reply frame from BTS, because TRAU does not indicate its TFO to enter status of fail, but enter wait state, thus solve because TRAU does not receive reply frame from BTS, cause its TFO to enter the problem of FAI state, thus improve the success rate that TFO sets up.
Preferably, according to the processing method of above-mentioned notification configuration frame, TRAU, when sending TFO preparation notification configuration frame to BTS first, starts timer (such as this timer can be 1 second); After expiration of the timer, TRAU indicates its TFO to enter status of fail.Like this, when sending TFO_SOON notification configuration frame, eliminate to retransmit to can not receive for n time and respond just failed restriction, but the timer transferring to state machine mechanism self to arrange going restriction.TRAU, when repeating transmission still can not receive reply n time, enters the state waited for and reply and do not send, if still can not receive reply after the timer expiry of protocol state machine, just indicates its TFO to enter status of fail.Therefore, avoid TFO in TRAU and live through long wait when can not receive reply for a long time, thus improve the success rate that TFO sets up.
In addition, after the TFO in TRAU enters status of fail, no matter whether there is the configuration interactive do not completed before, send TFO to BTS immediately and close notification configuration frame.For keeping the state consistency of base station and TRAU.
