Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of sending method of up expansion control bit of half-rate TRAU frame.
Background technology
Current GSM (Global System for Mobile Communications, global system for mobile communications) in the system, as TRAU (Transcoder/Rate Adaptation Unit, code conversion and Rate Adapter Unit) unit is away from BTS (Base Transceiver Station, when base station transceiver) holding, the control information exchange of voice, data and TRAU unit between the CCU of BTS (Channel Coding Unit, Channel Codec Unit) and the TRAU unit is carried out in the trau frame mode.The transmission of trau frame both can also can be carried out on the transmission channel at 8kbit/s at 16kbit/s.Agreement 3GPP (3rdGeneration Partnership Project, third generation partner program) TS 48.060 and 3GPP TS48.061 have stipulated the concrete trau frame form of transfer of data in the band.Trau frame has the fixed frame length of 20ms:
160bit (20ms)----8kbit/s (half rate)
320bit (20ms)----16kbit/s (full rate)
What agreement 3GPP TS 48.061 described is the frame format definition of the half rate transmission channel (Traffic Channel-Half-rate is abbreviated as TCH/H) of the voice-and-data of CCU unit and TRAU unit.The frame structure definition of the trau frame of HR (Half Rate, half rate) voice is as shown in table 1, and in the table 1, XC1～XC6 is up expansion control bit.Implication to up expansion control bit regulation in the prior art is the mapping relations (as shown in table 2) of an one-to-many, ambiguity will occur like this when the TRAU cell side is resolved.In the table 2, UFI is unreliable frame identification (Unreliable Frame Indication), BFI is bad frame indication (Bad Frame Indicator), TAF is time unifying sign (Time Alignment Flag), SID is silence descriptor (Silence Descriptor), and OP is parity check bit (Odd Parity of bits).Up expansion control bit is filled by the CHP (Channel Processor, channel processor) of CCU unit.
The frame structure definition of table 1TRAU frame
Provided below and occurred different example when the TRAU cell side is resolved up expansion control bit.
Example 1: when up expansion control bit XC1～XC5 was 01000 respectively, this can have three kinds of implications according to agreement:
(1)UFI＝0，BFI＝0，SID＝1，TAF＝0；
(2)UFI＝0，BFI＝1，SID＝1，TAF＝0；
(3)UFI＝0，BFI＝1，SID＝2，TAF＝0。
This needs the scheduler module oneself of TRAU unit to force a kind of implication of decision, selects implication (3) such as the scheduler module of TRAU unit, and the decoding unit of giving the TRAU unit UFI=0 of correspondence, BFI=1, SID=2 and TAF=0 is handled then.This just makes the TRAU unit can't determine the real meaning of the up expansion control bit representative of half-rate TRAU frame, thereby causes TRAU unit and CCU unit can't be consistent to the understanding of half-rate TRAU frame.

Below in conjunction with embodiment method of the present invention is further described in detail.
In the present embodiment, to the work of the up expansion control bit of half-rate TRAU frame following setting:
The XC1 position is UFI sign position: XC1=1 represents unreliable frame, and XC1=0 represents reliable frame;
The XC2 position is BFI sign position: XC2=1 represents bad frame, and XC2=0 has represented frame;
The XC3 position is TAF sign position: the XC3=1 representative time is adjusted, and the XC3=0 representative is not adjusted;
Two of XC4 and XC5 are SID and O ﹠amp; The sign position of M frame:

XC6 is the same with what stipulate in the existing protocol, still is parity check bit OP sign position.
Therefore, the up expansion control bit of back half-rate TRAU frame and the implication of its representative are set have just had man-to-man mapping relations.
On the basis of She Zhiing, the sending method of the up expansion control bit of half-rate TRAU frame comprises the steps: in the present embodiment in the above
The first step, the CHP of CCU unit judges whether decoded data are unreliable frames, if unreliable frame (being that UFI is 1) when the data of eating dishes without rice or wine to receive being carried out the up channel decoding, be 1 then, otherwise be 0 the XC1 position in the trau frame with the XC1 position in the half-rate TRAU frame;
In second step, CHP judges further whether decoded data are bad frames, if bad frame (being that BFI is 1), then the XC2 position with half-rate TRAU frame is 1, otherwise is 0 with the XC2 position of half-rate TRAU frame;
In the 3rd step, CHP judges further whether decoded data are new SID frames, is to be 1 with the XC3 position of half-rate TRAU frame then, otherwise is 0 with the XC3 position of half-rate TRAU frame;
In the 4th step, CHP further judges the affiliated type of decoded data, and type comprises good speech frame (non-SID frame), acceptable SID frame, effective SID frame and O ﹠amp under the described decoded data; The M frame, if good speech frame is 00 with XC4, the XC5 position of half-rate TRAU frame then, if acceptable SID frame, then XC4, the XC5 position with half-rate TRAU frame is 01, if effectively the SID frame is 10 with XC4, the XC5 position of half-rate TRAU frame then, if O is ﹠amp; The M frame is changed to 11 with XC4, the XC5 of half-rate TRAU frame, finishes.
Need to prove that each top step does not have sequencing, here we just for the convenience on narrating is described the method for the invention with step by step form, in other embodiments, each step can be carried out with other order.
Accordingly, in the present embodiment, the method for reseptance of the up expansion control bit of half-rate TRAU frame comprises the steps:
The first step when TRAU unit receives half-rate TRAU frame, reads the value of XC1～XC5 in the up expansion control bit and resolves, and judges the value of XC1, if the XC1 value is 1, then described half-rate TRAU frame is unreliable frame, if the XC1 value is 0, then is reliable frame;
In second step, the value of XC2 is further judged in the TRAU unit, if the XC2 value is 1, then described half-rate TRAU frame is a bad frame, if the XC2 value is 0, then has been frame;
In the 3rd step, the value of XC3 is further judged in the TRAU unit, if the XC3 value is 1, then described half-rate TRAU frame is new SID frame, if the XC3 value is 0, then is not new SID frame;
The 4th step, the value of the further XC4 in TRAU unit, XC5, if the value of XC4, XC5 is 00, then described half-rate TRAU frame is good speech frame, if the value of XC4, XC5 is 01, then is acceptable SID frame, if the value of XC4, XC5 is 10, then being effective SID frame, if the value of XC4, XC5 is 11, then is O ﹠amp; The M frame is resolved and is finished.
Below example 2 are situations at front example 1, again with the present invention to up expansion control bit be provided with the transmitting half-rate trau frame, the uncertain problem of up expansion control bit implication can not appear during the TRAU unit resolves.
Example 2: suppose that to the setting of up expansion control bit, we just can parse unique implication according to the present invention when up expansion control bit XC1～XC5 is 01000 respectively in the half-rate TRAU frame that up BTS sends up:
(1)UFI＝0，BFI＝1，TAF＝0，SID＝0。
As seen, the TRAU unit just can ambiguity not occur when resolving the implication of up expansion control bit like this.
The present invention as long as TRAU unit and control corresponding position, CCU unit are filled and resolution unit is done very little code revision, just can solve the uncertain problem of implication of up expansion control bit before on the basis that up expansion control bit is redefined.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
