In addition, DPCH is used separately by terminal, is therefore called as separate channel; Other channels, by the public use of a plurality of terminals, are therefore called as common signal channel.
Its action is then described.
First, GGSN2 takes out the multi-medium data of the content of being taken care of by service centre 1, and this multi-medium data is sent to SGSN3.
SGSN3 is when receiving multi-medium data from GGSN2,1 the above mobile communication terminal 6 that retrieves the distribution services of using this content, is transferred to the multi-medium data of these contents the base-station control apparatus 4 being connected with the base station 5 that has held these mobile communication terminals 6.
Base-station control apparatus 4, when receiving multi-medium data from SGSN3, is controlled base station 5 to utilize S-CCPCH that multi-medium data is sent from base station for 5 minutes.
But, even if mobile communication terminal 6 is just positioned in the compass of competency of the base station 5 of distributing multimedia data, for example, near the situation periphery that is positioned at compass of competency, from base station, 5 electric waves that send out can die down, and the quality of reception can variation.
Near the periphery of compass of competency, the reasons are as follows of the quality of reception variation of S-CCPCH channel.Here, for ease of explanation, suppose as shown in Figure 6, base-station control apparatus 4 is connected with base station B with base station A, and mobile communication terminal 6 is positioned near the periphery of compass of competency of base station A.
In this case, mobile communication terminal 6 is closer with the distance of base station B, and therefore, separate channel DPCH, except being set between mobile communication terminal 6 and base station A, is sometimes also set between mobile communication terminal 6 and base station B.
Between mobile communication terminal 6 and base station A, B, set in the situation of DPCH, by reception, utilized data that DPCH sends out from base station A, B and both sides' data are carried out to maximum ratio synthetic, just can improve the quality of reception of these data.
But because common signal channel S-CCPCH is only set between mobile communication terminal 6 and base station A or base station B, so it is synthetic to carry out the data that send out from base station A and base station B maximum ratio each other, its data receiver quality exists the trend of variation.
Therefore, the quality of reception in order to ensure S-CCPCH, increase the power of distributing to S-CCPCH in base station 5 and send, but, as mentioned above, when having increased base station 5 while distributing to the power of S-CCPCH, the transmitted power of distributing to other channels can reduce relatively, therefore the information quality of reception meeting variation of, utilizing other channels to send.
In the 1st execution mode, the quality of reception of distributing to the power of S-CCPCH and improving S-CCPCH in order not increase base station 5, makes mobile communication terminal 6 have structure as shown in Figure 2.
The following describes the action of the mobile communication terminal 6 of Fig. 2.Fig. 7 and Fig. 8 mean the flow chart of contents processing of the mobile communication terminal of the 1st execution mode of the present invention.
In addition, a plurality of base stations 5 and mobile communication terminal 6 between do not set stage of S-CCPCH, as wireless signal, can consider not send at once multi-medium data, but pilot signal transmitted; Also can send at once multi-medium data.
First, when antenna 11 receives the wireless signal being sent out by base station A or base station B and is multipath signal, this multipath signal is amplified in the low noise enlarging section 12 of mobile communication terminal 6.
When multipath signal is amplified in low noise enlarging section 12, the frequency of 13 pairs of these multipath signals of frequency conversion part converts and RF signal is outputed to A/D transformation component 14.
When receiving analog signal from frequency conversion part 13 and be RF signal, A/D transformation component 14 carries out analog/digital conversion by this RF signal, by digital signal, is that RF signal outputs to the synthetic portion 18 of RAKE and search section 15.
When receiving the RF signal of digital signal from A/D transformation component 14, search section 15 detects the transmission source base station 5 of this multipath signal by carrying out cell search process.That is, confirm the multipath signal received by antenna 11 be from base station A, send out or from base station B, send.
Particularly, movement along with mobile communication terminal 6, multipath signal can be subject to the impact of phasing and change, therefore, search section 15 is set the code of S-CCPCH or regularly etc. and carry out the search (step ST1) of S-CCPCH, thereby calculates corresponding S-CCPCH (S-CCPCH relevant to base station A, the S-CCPCH relevant with base station B) (step ST2) such as delay curves (profile).
Branch road distributes control part 17 to control the synthetic portion 18 of RAKE, makes to retrieve the peak value of the delay curve calculating by search section 15, and multipath signal during this peak value is assigned to the branch road portion (step ST3) of the synthetic portion 18 of RAKE.
Now, the base station 5 of monitored object is that Active Set is base station A, B, therefore, for example, if the transmission source of the multipath signal being received by antenna 11 is not yet to distribute from the RF signal of A/D transformation component 14 outputs on the 18a of branch road portion of the synthetic portion 18 of base station A and RAKE, branch road distributes 17 of control parts to control the synthetic portions 18 of RAKE so that this RF signal (hereinafter referred to as RF signal A-1) is assigned to the 18a of branch road portion.
In addition, if the transmission source of the multipath signal receiving by antenna 11 is to have distributed from the RF signal of A/D transformation component 14 outputs on the 18a of branch road portion of the synthetic portion 18 of base station A and RAKE, control the synthetic portion 18 of RAKE so that this RF signal (hereinafter referred to as RF signal A-2) is assigned to the 18b of branch road portion.
If the transmission source of the multipath signal receiving by antenna 11 is not yet to distribute from the RF signal of A/D transformation component 14 outputs on the 18c of branch road portion of the synthetic portion 18 of base station B and RAKE, branch road distributes 17 of control parts to control the synthetic portions 18 of RAKE so that this RF signal (hereinafter referred to as RF signal B-1) is assigned to the 18c of branch road portion.
In addition, if the transmission source of the multipath signal receiving by antenna 11 is to have distributed from the RF signal of A/D transformation component 14 outputs on the 18c of branch road portion of the synthetic portion 18 of base station B and RAKE, control the synthetic portion 18 of RAKE so that this RF signal (hereinafter referred to as RF signal B-2) is assigned to the 18d of branch road portion.
Code generator 16 generates the scrambler corresponding with the base station 5 detecting by search section 15.For example, if the base station 5 of the transmission source of this multipath signal is base station A, generate the scrambler corresponding with this base station A, if the base station 5 of the transmission source of this multipath signal is base station B, generate the scrambler corresponding with this base station B.
When input rf signal A-1～B-2, the 18a of the branch road portion～18d of the synthetic portion 18 of RAKE utilizes the scrambler being generated by code generator 16 by this RF signal A-1～B-2 demodulation.
When RF signal A-1, A-2 are assigned to the 18a of branch road portion, 18b, it is synthetic that the synthetic 18e of portion in the synthetic Bu18 of RAKE community carries out maximum ratio by this RF signal A-1 and RF signal A-2, and this composite signal (hereinafter referred to as composite signal A) is saved in to community input store 19a (step ST4, ST5).
In addition, when RF signal B-1, B-2 are assigned to the 18c of branch road portion, 18d, it is synthetic that the synthetic 18f of portion in the synthetic Bu18 of RAKE community carries out maximum ratio by this RF signal B-1 and RF signal B-2, and this composite signal (hereinafter referred to as composite signal B) is saved in to community input store 19b (step ST4, ST5).
When the synthetic 18e of portion in the synthetic Bu18 of RAKE community is saved in community input store 19a by composite signal A, lsb decoder 20 is processed (step ST11, ST12) by carrying out to the fast decoding of this composite signal A (TurboDecode), whereby this composite signal A is decoded and decoded composite signal A is saved in the output storage 21a of community (step ST13).
In addition, when the synthetic 18f of portion in the synthetic Bu18 of RAKE community is saved in community input store 19b by composite signal B, lsb decoder 20 is processed (step ST11, ST12) by carrying out to the fast decoding of this composite signal B, whereby this composite signal B is decoded and decoded composite signal B is saved in the output storage 21b of community (step ST13).
For example, check the CRC result (step ST14) of decoded composite signal A, B, thereby confirm that this CRC result is normal composite signal.
In addition, selecting a CRC result is normal composite signal (step ST15), and this composite signal is outputed to common down channel acceptance division 23 (step ST16).
When common down channel acceptance division 23 receives the composite signal choosing by selection portion 22, if this composite signal is control information, just this composite signal is outputed to protocol processes portion 26; If this composite signal is application data, this composite signal is outputed to application handling part 27.
When protocol processes portion 26 receives while being the composite signal of control information from common down channel acceptance division 23, according to this control information, carry out the processing relevant to Control on Communication of the setting/release of channel or handing-over etc.
; if relevant to the multipath signal sending out from base station A from the composite signal of common down channel acceptance division 23 outputs; protocol processes portion 26 just carries out for setting the Control on Communication processing etc. of S-CCPCH between itself and base station A; if relevant to the multipath signal sending out from base station B from the composite signal of common down channel acceptance division 23 output, protocol processes portion 26 just execution is used for setting the Control on Communication processing etc. of S-CCPCH between itself and base station B.
Then, the multipath signal of the S-CCPCH that search section 15 search set by protocol processes portion 26, the synthetic portion 18 of RAKE carries out maximum ratio by a plurality of multipath signals that search by search section 15 and synthesizes, and lsb decoder 20 is saved in community output storage 21a by this composite signal.
As mentioned above by protocol processes portion 26 and base station A or base station B between set S-CCPCH after, when receiving from common down channel acceptance division 23 while being the composite signal of application data, application handling part 27 is just according to conversion process such as these application data execution sound encoding and decoding or image coding and decodings.
In addition, decoded composite signal in being kept at community output storage 21a is to report in the situation of information, because selection portion 22 is not carried out the selection of composite signal and processed, so report information acceptance division 24, receive this composite signal and output to protocol processes portion 26.
Even if the decoded composite signal being kept in the output storage 21a of community is application data or control information, the in the situation that of utilizing descending separate channel to send over by base station 5, because selection portion 22 is not carried out the selection of composite signal and is processed, so descending separate channel acceptance division 25 receives this composite signal, if this composite signal is application data, just this composite signal is outputed to application handling part 27, if this composite signal is control information, just this composite signal is outputed to protocol processes portion 26.
As known from the above, by means of the 1st execution mode, the relevant multipath signal of wireless signal to utilizing S-CCPCH to send out from a plurality of base stations 5 is distributed to each transmission source base station and by be that a plurality of multipath signals that same base station 5 is relevant carry out maximum ratio synthetic with transmission source, and by this composite signal decoding, the successful composite signal of selective decompression from this decoded composite signal, due to this structure, can obtain 5 yuan of base stations needs control transmitted power also can improve the effect of the quality of reception of wireless signal.
In addition, that in the 1st execution mode, represent is relevant RF signal A-1, the A-2 of multipath signal that the 18a of branch road portion, 18b input sends out to base station A, relevant RF signal B-1, the B-2 of multipath signal that the 18c of branch road portion, 18d input sends out to base station B; Distribution for the RF signal of the 18a～18d of branch road portion can be also arbitrarily, for example, also can be relevant RF signal A-1, A-2, the A-3 of multipath signal that the 18a of branch road portion, 18b, 18c input send out to base station A, the relevant RF signal B-1 of multipath signal that the 18d of branch road portion input sends out to base station B.
In addition, in the 1st execution mode, represented that RAKE synthesizes portion 18 and carried the synthetic 18f of portion in synthetic Bu18eHe community, community, but the function that the synthetic portion in synthetic Bu，Gai community, 1 community has the synthetic 18f of portion in synthetic Bu18eHe community, community concurrently also can only be carried in the synthetic portion 18 of RAKE.
In addition because the hardware of lsb decoder 20 in general circuit scale is larger, so what represent is to carry out decoding by lsb decoder 20 timesharing to process, but 2 lsb decoders can certainly be installed in the 1st execution mode.
Further, in the 1st execution mode, represented to install 2 community input store 19a, 19b and the example of 2 community output storage 21a, 21b has also been installed, but can certainly be configured to, only possessed respectively 1 memory simultaneously.
