Description
Technical field
The present invention relates to the technology of assigns packet data channel (PDCH) in communication system, particularly a kind of indicating terminal sends the method for the PDCH that data adopted.
Background technology
At present, terminal in communication system, will be when communication system network sends data as the terminal in GPRS (GPRS) system or global system for mobile communications (GSM), at first send the distribution up channel request of carrying the data service characteristic parameter to communication system network, this service feature parameter is for sending speed, time delay and the error rate etc. of data; Secondly, after the data service characteristic parameter that communication system network carries according to this request that receives is this terminal distribution PDCH, the PDCH that this distributed is indicated to this terminal; At last, this terminal sends data by the indicated PDCH of wireless communication system.
Communication system network is that the process of terminal distribution PDCH is: communication system network is terminal distribution Temporary Block Flow (TBF), and TBF specifies the current operable one or more PDCH of this terminal.Any one PDCH that terminal in the communication system can use communication system network to set in advance, but accept the control of communication system network, because a plurality of terminals that may have in the communication system in different time or identical time are used identical PDCH channel.Communication system network comes the current operable one or more PDCH of indicating terminal by uplink state sign (USF).Below describe the how uplink data sending of the current operable one or more PDCH of indicating terminal of the notion of the PDCH that wireless communication system sets in advance and USF in detail.
The PDCH schematic diagram that Fig. 1 is provided with for communication system network: the time slot that communication system network is identical with every frame is formed a PDCH, as, i, i+1 ..., the time slot 0 of i+n, i+n+1 frame forms PDCH0, when communication system network carries out the resource allocation of up channel, all be unit with PDCH.
Fig. 2 is USF current operable one or more PDCH of indicating terminal how: communication system network is that in fact the TBF of terminal distribution is exactly the current operable one or more PDCH combinations of terminal, as: the TBF that distributes for terminal 1 is PDCH0, PDCH2 and PDCH5, during the current operable one or more PDCH of USF indicating terminal, each PDCH that communication system network sets in advance has a USF value (PDCH can only have 8 USF values at most) that belongs to terminal, as communication system network is that PDCH0 among the TBF that distributes of terminal 1 is x1 corresponding to the USF of terminal 1, PDCH2 is x2 and PDCH5 corresponding to the USF of terminal 1 corresponding to the USF of terminal 1 is x3, communication system network will send to terminal corresponding to the USF of terminal by down channel for the one or more PDCH among the TBF of terminal distribution, and terminal is determined current operable one or more PDCH according to the PDCH of the USF correspondence that receives.
Thereby communication system can have multiple by down channel to the method that terminal sends the presently used PDCH of USF distributing terminals: dynamic assignment, extended dynamic allocation and dynamic assignment (B2DA) etc. back-to-back.Respectively these three kinds of methods of salary distribution are elaborated below.
Dynamic assignment
Thereby Fig. 3 sends the method schematic diagram of the presently used PDCH of USF distributing terminals for communication system adopts dynamic assignment to terminal by down channel.The PDCH's that terminal monitoring wireless communication system in the communication system is provided with for this terminal in advance is descending, and when descending when receiving corresponding to self USF, terminal sends data at this PDCH up next (Block).The use of USF as shown in Figure 3, be assumed to be terminal 1 and distribute PDCH1, terminal 1 is x1 (setting in advance PDCH1 is x1 corresponding to the USF of terminal 1) at the descending USF of receiving of first frame by PDCH1, and terminal sends data at the up next Block of PDCH1 first frame; It is x1 that terminal does not receive USF at descending second frame of PDCH1, and then terminal does not send data at the up next Block of PDCH1 second frame.
As can be seen from Figure 3, the up distribution of each PDCH all is by the USF decision of PDCH corresponding to terminal, therefore, there is the big shortcoming of terminal power consumption in this distribution method: when terminal has been assigned with a plurality of PDCH, this terminal just must be monitored the descending of the PDCH identical with distributing the PDCH data, thereby receive the USF corresponding to terminal that is distributed and send data, this can make terminal power consumption big.
Extended dynamic allocation
Extended dynamic allocation method causes the big shortcoming of terminal power consumption to develop in order to overcome dynamic allocation method.The process of extended dynamic allocation is: terminal intercept communications grid side descending for each PDCH of terminal distribution in advance one by one, but at first intercept communications grid side is the descending of the minimum PDCH of the timeslot number of terminal distribution in advance, if when receiving, then use next Block to send data more than or equal to the up present frame of the PDCH of the time slot of the timeslot number of the PDCH place time slot of being monitored corresponding to self USF; If when not receiving corresponding to self USF, then intercept communications grid side is that the PDCH of time slot of the high timeslot number of PDCH of the minimum time slot of the ratio timeslot number of terminal distribution is descending in advance, up to receive corresponding to self USF or monitored all in advance for the PDCH of the time slot of terminal distribution descending till.When carrying out extended dynamic allocation, communication system preferentially indicates the user to use up as the PDCH of the highest time slot of the timeslot number of terminal distribution, promptly at the descending transmission of the PDCH of the highest time slot of the timeslot number that is terminal distribution USF corresponding to terminal, terminal is after this PDCH receives, at the uplink data sending of this PDCH.
Thereby Fig. 4 sends the method schematic diagram of the presently used PDCH of USF distributing terminals for communication system adopts extended dynamic allocation to terminal by down channel: be assumed to be terminal distribution PDCH1, PDCH2 and PDCH3, the first behavior time slot among the figure, this time slot is represented the descending situation for the PDCH of self distribution that terminal is monitored at every frame respectively with each frame of arrow indication, and blank box is represented not monitor; Second behavior communication system network receiving terminal when the next Block of present frame sends the time slot of data, the terminal that arrow refers to of pointing to this time slot is according to the descending situation of monitoring the PDCH that is distributed, the next Block of the up present frame of the PDCH that is distributed send data or etc. data conditions to be sent.As can be seen from Figure 4, terminal is monitored descending for the PDCH of self distributed time slot number minimum time slot in that present frame is preferential, only do not listening to corresponding to behind self USF, just can monitor descending into the PDCH of number high time slot of self distributed time slot successively at present frame, and in case receive corresponding to behind self USF, just no longer monitor PDCH descending of the time slot higher, and directly use all timeslot numbers to be not less than to receive the up next Block transmission data of the PDCH of the corresponding PDCH of USF place time slot at present frame than the timeslot number that receives the corresponding PDCH of USF place time slot at present frame.
But, extended dynamic allocation method exists the not high shortcoming of telecommunication system resources utilance: the PDCH method of salary distribution of supposing to have two terminals as shown in Figure 5, the data volume that this moment, terminal 1 will send is less, only need the up of a PDCH just can send, so communication system network will distributing terminals 1 (this is determined by extended dynamic allocation method in the up transmission of the PDCH of time slot 3, preferential use the up transmission of the PDCH of high time slot), the data volume that this moment, terminal 2 will send is big, but because the up of PDCH of time slot 3 taken by terminal 1, so terminal 2 can only be used PDCH up of time slot 4, this can cause time slot 0, the ascending resource waste of the PDCH of time slot 1 and time slot 2 makes the telecommunication system resources utilance not high.
B2DA
In order to improve the telecommunication system resources utilance, B2DA has been proposed.The basic principle of B2DA is exactly to make terminal preferentially use the uplink data sending of the PDCH of institute's distributed time slot number low time slot.At this moment terminal only distribution PDCH the descending reception of PDCH of time slot of minimum timeslot number corresponding to self USF, have and be the same number of USF of PDCH of this terminal distribution at the PDCH of this minimum time slot.After terminal received the USF of certain PDCH correspondence of distributing in the PDCH of this minimum time slot descending, the next Block of present frame that uses all timeslot numbers not to be higher than the PDCH of this PDCH place time slot sent data.When carrying out B2DA, communication system preferentially indicates the user to use uplink data sending as the PDCH of the minimum time slot of the timeslot number of terminal distribution, promptly at the descending transmission of the PDCH of the minimum time slot of the timeslot number that is terminal distribution USF corresponding to the PDCH of the minimum time slot of the timeslot number of terminal, after terminal receives, use the uplink data sending of PDCH of the PDCH place time slot of this USF correspondence.
Thereby Fig. 6 sends the method schematic diagram of the presently used PDCH of USF distributing terminals for communication system adopts B2DA to terminal by down channel, as can be seen from Figure 6, terminal is only monitored at the descending present frame for the PDCH of number minimum time slot of self distributed time slot, in case after receiving the pairing USF of PDCH that distributes into self, the up next Block at present frame of the PDCH of the PDCH place time slot of the USF correspondence of just using all timeslot numbers not to be higher than to receive sends data.
The difference of Fig. 6 and Fig. 4 is terminal not only only in the descending monitoring for the PDCH of number minimum time slot of self distributed time slot, and is not the descending monitoring of the PDCH of number high time slot of self distributed time slot at other; And be that communication system allows terminal use the uplink data sending of number low PDCH of institute's distributed time slot earlier, so just can improve the telecommunication system resources utilance, the PDCH method of salary distribution of supposing to have two terminals as shown in Figure 7, the data volume that this moment, terminal 1 will send is less, only need the up of a PDCH just can send, so communication system network will distributing terminals 1 in the up transmission of the PDCH of time slot 0, the data volume that this moment, terminal 2 will send is big, communication system network will distributing terminals 2 at time slot 1, time slot 2, the uplink data sending of the PDCH of time slot 3 and time slot 4, thus the waste of telecommunication system resources can not be caused.
But, B2DA also exists shortcoming: the USF that sends the PDCH correspondence that promising this terminal distributes for the following behavior terminal of the PDCH in the time slot number minimum by terminal institute distributed time slot, at present in the PDCH that is number minimum time slot of terminal institute distributed time slot, a terminal will take and the identical USF of PDCH quantity distribution, and the USF among PDCH can only be provided with 8, this can cause into the utilance of the USF among the PDCH of number minimum time slot of terminal institute distributed time slot low.For example: communication system network is that terminal 1 and terminal 2 have been distributed time slot 0 respectively, time slot 1, time slot 2, time slot 3, the PDCH of time slot 4 and time slot 0, time slot 2, time slot 3, the PDCH of time slot 4 and time slot 5, the USF that at this moment just all can't be distributed to the PDCH of terminal 1 and terminal 2 respectively identifies in the PDCH of time slot 1, and (terminal 1 and terminal 2 are divided into and have joined 10 PDCH, and 8 USF can only be arranged among the PDCH of time slot 0, can't be corresponding one by one), therefore, caused to the utilance of the USF of the PDCH of number minimum time slot of terminal institute distributed time slot is low, made the PDCH that can't be designated as a plurality of terminal distribution for the PDCH of number minimum time slot of terminal institute distributed time slot fully with USF.Correspondingly, USF is set according to this method, for the utilance of the USF of the PDCH of other time slots of terminal distribution also low.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of indicating terminal to send the method for the PDCH that data adopted, this method can overcome the low defective of utilance for the USF of the PDCH of terminal institute distributed time slot under the situation that does not influence the telecommunication system resources utilance.
According to above-mentioned purpose, technical scheme of the present invention is achieved in that
A kind of indicating terminal sends the method for the Packet Data Channel PDCH that data adopted, is being among pre-assigned each PDCH of terminal, and the uplink state sign USF of this terminal of sign corresponding to this PDCH is set, and this method also comprises:

Before steps A 1, this method also comprises: this terminal sends the distribution up channel request of carrying the data service characteristic parameter to communication system network; One or more PDCH that the data service characteristic parameter that communication system network carries according to this request that receives uses for this terminal distribution present frame; The descending transmission of the PDCH of the time slot that the timeslot number that communication system network uses at the present frame that is this terminal distribution is the highest is corresponding to the USF of this terminal.
Communication system network for the process of one or more PDCH that this terminal distribution present frame uses is: one or more PDCH that communication system network adopts extended dynamic allocation method to use for this terminal distribution present frame; Perhaps communication system network is the PDCH of the low time slot of pre-assigned timeslot number for one or more PDCH of this terminal distribution use.
A kind of indicating terminal sends the method for the Packet Data Channel PDCH that data adopted, is being among pre-assigned each PDCH of terminal, and the uplink state sign USF of this terminal of sign corresponding to this PDCH is set, and this method also comprises:
A2, according to the timeslot number order from low to high of PDCH place time slot, whether this terminal receives the USF of self correspondence successively at the descending monitoring present frame of pre-assigned PDCH, till the highest PDCH of pre-assigned timeslot number, if, execution in step B2; Otherwise, process ends.
B2, this terminal determine that according to the timeslot number of the PDCH place time slot that receives self corresponding USF present frame can select the up next Block at present frame of the PDCH of one or more low time slots of pre-assigned timeslot number to send data with the number of PDCH place time slot in the number range of determined time slot;
Described this terminal determines that present frame can be with the process of the number of PDCH place time slot:
The timeslot number of the PDCH place time slot of self corresponding USF that this terminal will receive and the timeslot number of pre-assigned PDCH place time slot compare, the figure place that timeslot number was positioned at of the PDCH place time slot of self the corresponding USF that determines to receive, add one after the number of pre-assigned PDCH place time slot deducted definite figure place, obtaining present frame can be with the number of PDCH place time slot.

Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, below lift specific embodiment and, the present invention is described in more detail with reference to accompanying drawing.
For under the situation that does not influence the telecommunication system resources utilance, overcome the low defective of utilance for the USF of the distributed time slot PDCH of terminal institute, the present invention is in each PDCH that is terminal distribution, setting can only have one to be used to identify the USF of this terminal corresponding to this PDCH, this USF is unique in each PDCH, and being used to of being provided with among the different PDCH identifies this terminal and can be the same or different corresponding to the USF of this PDCH.Like this, a PDCH can distribute to 8 terminals at most, has improved the USF utilance among the PDCH.
Fig. 8 is the flow chart of the method embodiment one of the indicating terminal transmission PDCH that data adopted of the present invention, and its concrete steps are:
One or more PDCH that the data service characteristic parameter that step 801, communication system network carry according to this request that receives uses for the terminal distribution present frame.
At this moment, communication system network can adopt the extended dynamic allocation method of prior art, preferentially makes terminal use the PDCH of the high time slot of pre-assigned timeslot number.
In order further to avoid the waste of telecommunication system resources, communication system network also can preferentially make terminal use the PDCH of the low time slot of pre-assigned timeslot number.
Whether step 803, terminal have the USF of self correspondence at the descending monitoring present frame of the PDCH of the highest time slot of pre-assigned timeslot number, if, execution in step 804; Otherwise, execution in step 805.
Whether step 805, terminal have the USF of self correspondence at the descending monitoring present frame than the PDCH of the low time slot of time slot of current monitoring, if, execution in step 806; Otherwise, execution in step 807.
Adopt the method for extended dynamic allocation when communication system network, when preferentially making terminal use the PDCH of the high time slot of pre-assigned timeslot number, because the method for the PDCH that indicating terminal provided by the invention adopted is with the difference of the dynamic allocation method of prior art: when indicating terminal by being the descending present frame transmission of the highest PDCH of the timeslot number of this terminal distribution USF corresponding to terminal, and terminal is after receiving USF, and the up next Block at present frame of PDCH that is not higher than the time slot of the USF that receives self correspondence by timeslot number sends data.Therefore, method provided by the invention can be avoided the waste of telecommunication system resources.
Further, communication system network of the present invention can also preferentially make terminal use the PDCH of the low time slot of pre-assigned timeslot number, like this, just can avoid the waste of telecommunication system resources more.
Thereby Fig. 9 sends the method schematic diagram of the presently used PDCH of USF distributing terminals for communication system adopts the described method of Fig. 8 to terminal by down channel, as can be seen from the figure, terminal is preferentially monitored at present frame and is PDCH descending of high time slot of self distributed time slot number, only do not listening to corresponding to behind self USF, just can go successively to monitor descending for the PDCH of number low time slot of self distributed time slot at present frame, in a single day and after receiving USF corresponding to self, just no longer monitor PDCH descending of the time slot lower, and directly use one or more timeslot numbers not to be higher than to receive the up next Block transmission data of the PDCH of the corresponding PDCH of USF place time slot at present frame than the timeslot number that receives the corresponding PDCH of USF place time slot at present frame.
The present invention also provides another method can overcome the low defective of utilance for the USF of number minimum PDCH of terminal institute distributed time slot equally, but this method exists the waste of certain telecommunication system resources, but compare with extended dynamic allocation method, the waste of telecommunication system resources is so not serious.
This method is in each PDCH that is terminal distribution, also being provided with to have to be used to identify the USF of this terminal corresponding to this PDCH, this USF is unique in each PDCH, and being used to of being provided with among the different PDCH identifies this terminal and can be the same or different corresponding to the USF of this PDCH.
Figure 10 is the flow chart of the method embodiment two of the indicating terminal transmission PDCH that data adopted of the present invention, and its concrete steps are:
Whether step 1003, terminal have the USF of self correspondence at the descending monitoring present frame of the PDCH of the minimum time slot of pre-assigned timeslot number, if, execution in step 1004; Otherwise, execution in step 1005.
Terminal determines that according to the timeslot number of the PDCH place time slot of the USF that receives self correspondence the process of the number of the PDCH place time slot that present frame can be used is: terminal will receive the timeslot number of PDCH place time slot of USF of self correspondence and the timeslot number of pre-assigned PDCH place time slot compares, the figure place that timeslot number was positioned at of the PDCH place time slot of self the corresponding USF that determines to receive, add one after again the number of pre-assigned PDCH place time slot being deducted definite figure place, obtain the number of the PDCH place time slot that present frame can use.
Whether step 1005, terminal have the USF of self correspondence at the descending monitoring present frame than the PDCH of the high time slot of time slot of current monitoring, if, execution in step 1006; Otherwise, execution in step 1007.
In the described method of Figure 10, the timeslot number of the PDCH place time slot of the USF of self correspondence that terminal receives is big more, and operable PDCH is few more with regard to GC group connector; The timeslot number of the PDCH place time slot of the USF of self correspondence that terminal receives is more little, and operable PDCH is many more with regard to GC group connector.Illustrate: suppose that terminal has been assigned with PDCH0, PDCH2, PDCH5 and PDCH7, terminal is preferentially monitored the descending of PDCH0 at present frame so, if receive USF corresponding to self, then determine from present frame can with PDCH be 4 (PDCH0, PDCH2, PDCH5 and PDCH7), preferentially select PDCH0, PDCH2, PDCH5 and PDCH7 for use successively according to the order of timeslot number at the next Block of present frame; If do not receive USF corresponding to self at the descending present frame of PDCH0, then monitor the descending present frame of PDCH2, if receive USF corresponding to self, determine that then at the available PDCH of present frame self be 3 (PDCH0, PDCH2 and PDCH5), preferentially select PDCH0, PDCH2 and PDCH5 for use at the next Block of present frame successively according to the order of timeslot number; Successively, monitor the descending present frame of PDCH7,, determine that then at the available PDCH of present frame self be 1 (PDCH0), select PDCH0 for use at the next Block of present frame if receive USF corresponding to self.
From above-mentioned example as can be seen, terminal determines that according to the timeslot number of the PDCH place time slot of the USF that receives self correspondence the process of the number of available PDCH place time slot is: the timeslot number of the PDCH place time slot of self corresponding USF that terminal will receive and the timeslot number of pre-assigned PDCH place time slot compare, the figure place that timeslot number was positioned at of the PDCH place time slot of self the corresponding USF that determines to receive, add one after the number of pre-assigned PDCH place time slot deducted definite figure place, obtaining present frame can be with the number of PDCH place time slot.With above-mentioned example is example, if terminal is monitored the descending of PDCH0 at present frame, has received the USF corresponding to self, determine that then figure place is 1, because the number of pre-assigned PDCH place time slot is 4, then 4-1+1 is obtained 4, the number of available PDCH place time slot is 4.
Thereby Figure 11 sends the method schematic diagram of the presently used PDCH of USF distributing terminals for communication system adopts the described method of Figure 10 to terminal by down channel, as can be seen from the figure, terminal is preferentially monitored present frame descending for the PDCH of self distributed time slot number minimum time slot, only do not listen to corresponding to behind self USF at present frame, just can go to monitor successively present frame descending for the PDCH of number high time slot of self distributed time slot, and in case receive for behind self USF, just no longer monitor PDCH descending of the time slot higher than the timeslot number that receives USF correspondence PDCH place time slot at present frame, and directly determine to adopt the PDCH of several time slots to send data according to the timeslot number of PDCH place time slot of USF that receives corresponding to self, the preferential selection be the up next Block transmission data at present frame of PDCH of the low time slot of the timeslot number of terminal distribution in advance in the number of determining time slot.
Adopt the described method of Figure 10 to exist the waste of telecommunication system resources, Figure 12 has improved the schematic diagram of telecommunication system resources utilance for the present invention illustrates: suppose that terminal 1 adopts the described method of Figure 10 to distribute PDCH, terminal 2 adopts extended dynamic allocation method to distribute PDCH.When terminal 1 is used PDCH0 and PDCH1, need be at the descending USF that receives corresponding to self of PDCH2, so communication system network is no longer distributed to terminal 2 in current use with PDCH2 at present frame, this will cause the wasting of resources of PDCH2 at the next Block of present frame.If terminal 1 adopts the described method of Fig. 8 to distribute PDCH, just can not make the wasting of resources of PDCH2, thereby can not have the problem of telecommunication system resources waste at the next Block of present frame.
Method useful application provided by the invention as gprs system or global system for mobile communications GSM, also can be applied in the third generation system (3G) in second-generation system (2G).
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
