Description
Technical field
The present invention relates to global system for mobile communications (GSM; Global System of Mobilecommunications) network dynamic channel allocation (DCA; Dynamic Channel Allocation) technology; Relate in particular to the method for carrying out dynamic frequency and channel allocation (DFCA, DynamicFrequency and Channel Allocation) when customer call is set up.
Background technology
Under limited frequency spectrum resources, overcome interference, bigger capacity is provided, be the important topic of gsm system always.DCA is to reducing a kind of technology that interference and raising capacity have effect; It is the method for channel allocation based on interference adaptive that is the basis with the synchronizing network that wireless burst pulse BURST aligns along (rising/decline); Channel distributes (MA by moving; Mobile Allocation) (TS Timeslot) describes for tabulation, mobile distribution indicator index (MAIO, Mobile Allocation Index Offset) and time slot.When carrying out channel allocation; The interfered cell signal strength signal intensity that arrives according to mobile phone for measuring; In conjunction with each sub-district current channel actual allocated situation; Each assignable channel is carried out Signal Interference and Noise Ratio (SINR, signal to interference and noise ratio) prediction, thereby distribute channel with suitable SINR; Simultaneously, also to calculate, other connected the littler channel of influence and will select because there has been the interference of connection in new allocated channel to other, if cause the SINR of other connection not meet the demands, then this channel can not distribute.
In recent years; Be accompanied by the increase of people to the mobile voice service demand; The GSM network makes the mobile wireless resource more and more nervous also in expansion constantly, and then the technology of many raising spectrum utilization efficiencies occurred; Multi-user reusing-one-slot (MUROS, Multi-User Reusing-One-Slot) technology is wherein a kind of.The core concept of MUROS is through on a time slot, carrying two or more customer services simultaneously, thereby has improved the capacity of the utilization ratio and the whole system of frequency spectrum.If but use this technology, will certainly increase the interference strength between same time slot user, cause the decline of signal quality.
The general process of existing DFCA method is:
(1) user makes a call in this sub-district, is obtained the channel of " best " by uplink interference intensity record data; If channel does not also write down interfering data, think that then SINR is very big, the upstream sinr of this channel meets the demands; If all minimum SINR requirement of no show of channel, then channel allocation failure.
The sort method of above-mentioned channel allocation is: at first surpass in the channel of " target SINR " thresholding at SINR, preferentially select the lower channel of SINR; Then, surpass the higher channel of the preferential SINR of selection in the channel of " minimum SINR " thresholding at SINR.Wherein, " target SINR " and " minimum SINR " thresholding is directed against the special sound coding method with reference to the SINR shown in the table 1.
Table 1
| Link protection type | Target SINR | Minimum SINR |
| FR/EFR | 15dB | 10dB |
| HR | 18dB | 12dB |
| AMR?FR | 9dB | 4dB |
| AMR?HR | 15dB | 10dB |
Remarks:
EFR:Enhanced Full Rate, the EFR type;
Be a kind of coded system of GSM voice-over-net, be used for speech coding and the transmission of GSM mobile handset, can obtain more clear, more vivid voice quality, need Internet service provider to open this network function mobile phone and could cooperate realization based on full rate 13Kbps.
FR:Full Rate, the full rate type;
HR:Half Rate, the half rate type;
AMR:Adaptive Multi-Rate, AMR.
(2) calculate this user's descending SINR, see and to satisfy descending SINR requirement, if can meet the demands, then continue, otherwise select the channel of " inferior good " again to the first step.
(3) to existing the uplink interference that disturb to be connected user's (be this calling party's allocated channel and be interfered same adjacent user frequently) to calculate, see whether it still can satisfy " minimum SINR " threshold requirement; If all are already present disturb to be connected the user and satisfy this condition, then pass through, otherwise reselect a channel to the first step.
(4) disturbed the descending interference that connects the user to calculate to existing, seen whether it still can satisfy " minimum SINR " threshold requirement; Disturbed the connection user to satisfy condition if all have existed, then pass through, otherwise reselect a channel to the first step.
The problem of the existence of above-mentioned DFCA method:
In the GSM network of using the MUROS technology, a plurality of users can share a channel.For example user MS1 shares a channel with user MS2, gives an example with uplink receiver, establishes make an uproar at the bottom of the base station receiver (being the intrinsic noise of receiver) and is I0, and the reception signal of establishing from MS1 is E1, except that MS2 is I1 with the interference strength the interference frequently; Reception signal from MS2 is E2, and except that MS1 is I2 with the interference strength disturbing frequently, then the upstream sinr of user MS1 and MS2 is respectively:
SINR1＝E1/(E2+I1+I0)；
SINR2＝E2/(E1+I2+I0)；
If E1≤E2, then SINR1 < 0; Otherwise, if E1>and E2, then SINR2 < 0.Find out that thus under any condition, the SINR that among the MUROS user MS1 of a shared channel and the MS2 user must be arranged is less than 0; And when SINR1 was big, SINR2 was inevitable less, and vice versa.Though can be in the admittance process; Consider to let the similar user of channel quality share same channel; So that its SINR is suitable, yet because the complexity and the time variation of wireless channel environment, its signal quality was difficult to be guaranteed simultaneously when two MUROS users always shared same channel.And the performance performance in traditional gsm wireless channel allocation of existing DFCA method is excellent, but can't directly apply to MUROS user's channel allocation.
Therefore in the GSM network of supporting the MUROS technology, adopting reasonable method, make full use of the interference profile effect of DFCA method, is the key of raising system antijamming capability in MUROS uses.

Embodiment
Technical scheme main points of the present invention are that the base station is the individual channel of MUROS user's primary distribution N (>=2) when Serving cell has user's call setup; Promptly at first, the calling party satisfies all channels that insert the minimum SINR threshold requirement of user for finding to its link protection type; From all channels of finding out, select then and can satisfy all and existed and disturb to be connected N the channel of user, and number of channel N is more than or equal to minimum number of available channels M to the minimum SINR threshold requirement of uplink and downlink of its link protection type; After all channel allocation successes, the base station will become the channel notification of the distribution of work to give the user, and the user just takes turns to operate in N the channel that distributes in order.
Technique scheme of the present invention is described in further detail and explained below in conjunction with accompanying drawing and specific embodiment.
The used parameter of present embodiment is joins under the simulated environment, and real system is according to the concrete property configuration of base station equipment.
As shown in Figure 1, the present embodiment method comprises following process step:
101: " minimum SINR " thresholding and the minimum number of available channels M that distributes MA tabulation and all types of users moved in the base station initialization, and be as shown in table 2;
Table 2
| Link protection type | Insert the minimum SINR of user | There has been the minimum SINR of user | Minimum number of available channels M |
| FR/EFR | 6dB | -4dB | 2 |
| HR | 8dB | -2dB | 2 |
| AMR?FR | 4dB | -6dB | 2 |
| AMR?HR | 6dB | -4dB | 2 |
For example, when user MS1 made a call, if EFR (EFR, Enhanced FullRate) type need be distributed to its N=2 channel CH1, CH2, these two channels must satisfy the requirement that MS1 up-downgoing SINR is higher than 6dB; When MS1 is operated in one of above-mentioned 2 channels; If already present the interference connects FR or EFR type in user's table 2; Then its uplink and downlink SINR must be higher than-4dB, is disturbed when connecting the user if other type is already present, and its uplink and downlink SINR requires can obtain with reference to table 2 equally.
102～109: the base station begins all sub-districts of poll, wherein:
102: whether this sub-district has the user to make a call, if having, then execution in step 103; Otherwise, forward step 109 to and carry out;
103～104: according to this cell measurement reporting; In conjunction with the disturbance records data; Find out to this user's link protection type and can satisfy all channels that insert the minimum SINR threshold requirement of user uplink, and judge that the number of channel of finding out channel is whether more than or equal to the minimum number of available channels M to this user's link protection type; If execution in step 105, execution in step 108 then if not;
That is in all of available MA tabulation can the up Signal to Interference plus Noise Ratio matrix for said calling party's allocated channel, find out all L channel that can satisfy the minimum SINR threshold requirement of this user uplink, and L must be more than or equal to M; In the descending Signal to Interference plus Noise Ratio matrix of all L channel that available MA tabulates, find out all O channel that can satisfy the descending minimum SINR threshold requirement of this user, and O must be more than or equal to M then.
For example there are a broadcast channel (BCCH, Broadcast Channel) and two Traffic Channels (TCH, Traffic Channel) carrier frequency in certain sub-district; Wherein the MA list length of TCH channel is 9, and the TCH full speed channel kind number that then possibly distribute is:
8 (timeslot number) * 9 (MA length)=72;
Certainly, the actual TCH full speed channel quantity that can distribute is:
8 (timeslot number) * 2 (TCH carrier frequency number)=16
The promptly actual full speed channel quantity that can distribute is 16, greater than minimum number of available channels M (=2).
105～106: according to this cell measurement reporting; In conjunction with the disturbance records data; All already present uplink and downlink Signal to Interference plus Noise Ratio that connect the user that disturbed when distributing this user on all channels that estimation is found in step 103～104; Therefrom select and to satisfy all and already presently disturbed N channels that connect the minimum SINR threshold requirement of user's uplink and downlink, and judge that number of channel N is whether more than or equal to the minimum number of available channels M of the link protection type that is directed against this user to the already present link protection type that disturb to be connected the user; If execution in step 107, execution in step 108 then if not;
That is estimate that all are already present by up Signal to Interference plus Noise Ratio of interference connection user when on all O channel, distributing this user; Therefrom select and to satisfy already present P the channel that is disturbed the minimum SINR threshold requirement of connection user uplink, and P must be more than or equal to M to link protection type; Estimate all already present descending Signal to Interference plus Noise Ratio that connect the user that disturbed when on all P channel, distributing this user then; Therefrom select and to satisfy already present N the channel that is disturbed the descending minimum SINR threshold requirement of connection user, and N must be more than or equal to M to link protection type.
107: notification channel distributes successfully; Execution in step 109;
All channels that this sub-district record obtains by step 160; And write down all uplink interference that had link and descending interference; To on each channel of sub-district/descending interference adds up respectively; And calculate the mean value of uplink interference and the mean value of descending interference respectively, and result of calculation is stored as the disturbance records data.Simultaneously, N channel notifying this MUROS user to distribute.
In communication process, sub-district and user work (simply, can mode in order pressing the frame circulation) by frame in N channel evenly distributedly.2 channels that are assigned to like MUROS user MS1 are respectively channel 1 and channel 3, and then this user works in channel 1, the 2 frame at the 1st frame of call setup and works in channel 3; The 3rd frame works in channel 1 again; The 4th frame works in channel 3 again, by that analogy, finishes to discharge channel up to user's communication.
108: notification channel distributes failure;
109: check whether poll finishes all sub-districts; If process ends is then pointed to next sub-district if not and is returned step 102 execution.
The present invention can improve MUROS user's speech quality under the condition that does not increase base station and mobile phone complexity; Base station end only need utilize the measurement report of reporting of user to distribute a plurality of channels for the call setup user; And will become the user of a plurality of channel notification call setups of the distribution of work, then the successful user's rotation of this call setup uses a plurality of channels that distribute to get final product.The present invention can reach interference profile effect more excellent under the MUROS environment, and is all significant to improving system's antijamming capability and elevator system capacity.
The above is merely preferred embodiment of the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
