Description
Technical field
The invention belongs to field of satellite mobile communication, and in particular to a kind of more USF processing applied to satellite communication system
Method.
Background technology
Satellite communication system has and can provide the seamless coverage of wider range at lower cost, not limited by geographical conditions
Feature.Satellite communication system capacity is very big, and can distribute according to need to each user, disclosure satisfy that education, enterprise and family
Etc. a variety of different data communication needs.
GMR（GEO-Mobile Radio interface）The GMR-1 of family of standards corresponds to GSM standard, has been applied to
Middle East Thuraya satellite communication systems, evolution version GMR-1 3G correspond to EDGE（Enhanced Data rates for GSM
Evolution）Standard.
GPRS/EGPRS at present（EDGE）Using based on USF in network（Uplink State Flag, uplink
Status Flag）The ascending resource method of salary distribution：Network is establishing uplink TBF（Temporary Block Flow, Temporary Block Flow）
When, give terminal distribution one USF, terminal monitors downlink PDCH（Packet Data Channel, grouped data share channel）On
Radio block show the end if the USF carried in the head of some radio block is identical with the USF of oneself is distributed to
End can carry out data transmission in next or multiple radio block of the corresponding uplink PDCH of downlink PDCH.But due to
USF fields only have 3 information bits, so, on a PDCH within the same TBF periods, can only at most there are 23 powers
Different USF can only at most be multiplexed 8 terminals, to limit the access of other-end.
GMR-1 3G standards use the multiplex mode being combined with frequency division the time-division.To support the grouped data of different rates to pass
It is defeated, a variety of PDCH are defined, using suffix（M, n）It distinguishes, m indicates that PDCH occupied physical channel bandwidth is m*BW1（m=
1,2,5,10；BW1For primary channel transmission bandwidth）, the occupied physical channel slot number of n expression bursts.
Various logic channel on up/down PDCH uses different types of burst, grouping normal burst to be denoted as PNB (m, n).
The wireless block structures of PNB of down direction are as shown in Figure 1, contain PUI（Public Information, public information）, one can
The ULMAP of choosing（Uplink Map, uplink map）And load.ULMAP is made of multiple USF.The PNB of up direction is wireless
Block structure is as shown in Fig. 2, contain PUI and load.
The PNB of down direction（M, n）Have in the same burst is one or more MES（Mobile Earth
Station, mobile terminal）It is multiplexed the ability of RLC/MAC blocks.On the different frequency channel of uplink, it is understood that there may be multiple
MES uses different outburst type simultaneous transmissions, as shown in Figure 3.Transmission is by corresponding downlink while uplink direction
PUI and ULMAP in burst are indicated.
Allow maximum transmission PNB in downlink（10, n）, but only allow maximum transmission PNB in up direction（5, n）, for regarding
The big datas high-rate services such as frequency passback, it is difficult to meet requirement of real-time.
The prior art concentrates on GPRS/EGPRS protocol architectures about USF processing methods, and is only at single USF
Reason.And the part PUI and ULMAP of downlink burst can carry multiple USF in GMR-1 3G standards, in having agreement, about
More USF processing, agreement only propose a kind of demand and as a result, as to how realize not related motion.In related patents skill
In art, there is no more USF for GMR-1 3G standards to handle patent.

4. a kind of more USF processing methods applied to satellite communication system, it is characterised in that：Include the downlink of (10,5) PDCH
PUI field formats, in the downlink PUI field formats of the PDCH (10,5), reverse frequency is divided into two groups, wherein USF1 and
A set of frequencies is related, and USF2 is related to the second class frequency, and it is 5*BW that every group, which all contains there are one value,1Maximum total bandwidth, this two
Between group or any group of intercarrier frequency is not required adjacent, and MES can be assigned to any class frequency, and assignation information is immediately
It is indicated in assignment messages；In the downlink PUI field formats of the PDCH (10,5), UAT fields indicate uplink assignment type, when
When the value of UAT is " 0000 ", if inverse bandwidth is an adjacent 10*BW1, while the value of USF1 is identical with USF2, then with
PNB (10,5) that the associated MES of USF are used on reversed PDCH is transmitted.
5. a kind of more USF processing methods applied to satellite communication system according to claim 4, it is characterised in that：Institute
In the downlink PUI field formats for stating PDCH (10,5), the size of ULMAP is 8 bytes, and preceding 4 bytes are used for the first class frequency, after
4 bytes are used for the second class frequency, and contain up to 8 USF according to UAT fields；When ULMAP is used for certain a set of frequencies, PUI
It is made of one group of 5 USF for 5 PNB (1,10) distribution with the USF in ULMAP, PNB (1,10) distribution starts from minimum
The carrier wave of frequency, two PNB (1,10) distribution on side frequency carrier wave with identical USF value will be considered as a PNB
(2,10) it distributes.
6. a kind of more USF processing methods applied to satellite communication system according to claim 4, it is characterised in that：Institute
In the downlink PUI field formats for stating PDCH (10,5), MES when receiving downlink burst on downlink PDCH (10,5), according to
The processing step of the downlink PUI field formats of PDCH (10,5) is as follows：
(1) MES handles E, MCS parameter successively；
(2) if UAT=0, no ULMAP fields are transferred to (3)；If UAT=1,2,3 there are ULMAP fields, it is transferred to (7)；If UAT=
Other values are transferred to (11)；
(3) two USF in PUI are assigned to in advance compared with the USF of this MES respectively, record matchFlag,
PollUsf, pollNumber, usfAbnormalflag parameter；If some USF in the PUI and USF for being assigned to this MES in advance
It is equal, then successful match；
(4) if USF successful match, and mark without exception is transferred to (5), is otherwise transferred to (11)；
(5) pollUsf number j corresponding in PUI are searched, the group of frequencies where allowing the MES to send is number j, is carried
Frequency initial position is 0；
(6) if pollNumber=1, PNB (5,5) is sent；If pollNumber=2, PNB (10,5) is sent；It is transferred to
(11)；
(7) according to UAT values, the USF in the two USF and ULMAP in PUI is formed ordered queue, USF [] is denoted as, USF
USF in [] is assigned to in advance compared with the USF of this MES respectively, record matchFlag, pollUsf, pollNumber,
UsfAbnormalflag parameters；If some USF in USF [] is equal with the USF for being assigned to this MES in advance, successful match；
(8) if USF successful match, and mark without exception is transferred to (9), is otherwise transferred to (11)；
(9) pollUsf first time number j corresponding in USF [] are searched, divide situation according to UAT values, calculate frequency group number with
Carrier frequency initial position；
(10) if pollNumber=1, and pollUsf is the USF in PUI, then sends PNB (5,5)；If pollNumber=1,
And pollUsf is the USF in ULMAP, then sends PNB (1,10)；If pollNumber=2, and pollUsf is only in ULMAP
USF, then send PNB (2,10)；If pollNumber=2, and pollUsf is both the USF in PUI and in ULMAP, then
USF mistakes are transferred to (11)；If pollNumber>2, then USF mistakes, are transferred to (11)；
(11) terminate.
